Abstract

When performing an end-to-side anastomosis connecting the end (10) of a firs t vessel (9) to the edge region (12) around an opening in the side wall of a second vessel (11), an instrument (1) is used having a circumferential stapling anvil (3) secured to an anvil tube (2) accommodating the first vess el (9), the end of which is everted about the anvil (3) with the intima of the end region (10) facing the intima of the edge region (12), when the instrume nt (1) with the first vessel (9) in place has been inserted into the opening in the second vessel (11). Then, a clamping tube (5) is advanced towards the anvil (3), clamping the end (10) and edge region (12) together against the anvil (3). In the next step, a number of stapling plungers (6) carrying staples (7) are advanced towards the anvil (3), the latter having staple- bending surfaces (4), thus stapling the two vessels together in a manner not shown. Finally, the clamping tube (5) and the stapling plungers (6) are withdrawn, and the whole instrument removed from the anastomosis.

Description

METHOD AND ANASTOMOTIC INSTRUMENT FOR USE W~-IEN PERFORMING
AN END'-TO-SIDE ANASTOMOSIS
TECHNICAL FIELD
The present invention relates to a method of the kind set forth in the preamble of claim 1.
BACKGROUND ART
A method of this kind is disclosed in the international application having the publication No. WO 95/17128. In this previously known method, the means used for inter-connecting the two vessels consisted of an open springy brace carrying spikes and being capable of being bent elastically so as to make its free ends cross each other, said :pikes forming angles with the brace gradually diminishing from acute angles at the free ends to substantially right angles mid-way between them. When released from the anastomotic instrument holding the brace in the elastically bent condition, it would bring the spikes into engagement with the regions to be joined so as to penetrate the latter and so to speak nail them together.
Extra-clinical trials have, however, shown that one can not always be certain that all the spikes have penetrated through the parts concerned of the two vessels to be joined, this probably being due to the limited elastic force .available from the springy brace.
DISCLOSURE OF THE INVENTION
It is the object of the present invention to provide a method of the kind referred to above, with which it is possible to achieve a more reliable connection between the two vessels forming the anastomosis, and this object is achieved by proceeding as set forth in the characteriz-ing clause of claim 1. With this arrangement, the parts concerned of the two vessels to be joined are connected to each other through a stapling operation based on the same principles as other surgical stapling devices and - inc:identally - ordinary office staplers.
As already indicated above, the use of stapling devices in surgical work is not unknown, but until now only in situations, in which it is possible to move the organ or organs to be operated upon from their normal position in Z5 the patient's body, such as in the abdominal cavity, to a position - not infrequently outside the patient's body - in which the anvil member, against which the staples are bent (corresponding to the lower part of an office stapler), can be placed on the side of the joint concerned facing away from the stapling plungers (corresponding to the p7_unger in the top part of an office stapler). Thus, the present invention is the first to offer what could be called "in-situ stapling". To make this possible, the present invention prescribes the use of an anastomosis instrument capable of performing the following four functions:
a cruidincr function, i.e. guiding the instrument carrying the first vessel into the opening having been formed in the side of the second vessel, :30 - an arranging function, i.a. urging the edge of the opening to the second vessel into a shape and position corresponding to the shape and position of t:he end region of the first vessel preparatory to - a stapling function, in which the parts of the two vessels having been brought into contact through the arranging function are positively joined by a stapling operation, and - a removal function, in which the instrument after S completion of the stapling operation is removed from the joint formed by being luxated out of the pocket formed on the everted end of the first vessel, said pocket then unfolding simultaneously with a slight withdrawal of the first vessel.
At this point it should be emphasized that, using a preferred embodiment of the instrument, in which there is a rigid mechanical connection between the anvil member and the part of the instrument adapted to be gripped manually by the operating surgeon, both the guiding function and the arranging function referred to above may be carried out with the best possible "feel", as the surgeon will be able- to sense manually any objects encountered by the anvil member, including - of course - the second vessel and the anastomotic opening formed therein.
All the functions described above may be carried out without removing the organs concerned through any significant distance away from their normal functional position in the body, making the method according to the invention eminently suitable for coronary by-pass operations. Thus, the expression "in-situ stapling" would appear justified.
The present invention also relates to an anastomotic instrument for carrying out the method according to the invention.

-3a-According to the invention, there is provided an anastomotic instrument, characterized by:
a) a first elongate member, to one end of which is rigidly secured a circumferential anvil member in such a manner, that said first vessel may be placed within said first elongate member with its end region everted about said anvil member with the terminal part of said end region facing towards the opposite end of said first elongate member, b) staple-bending recesses provided in said anvil member and facing towards said opposite end, c) a second elongate member longitudinally moveable relative to said first elongate member and adapted to be moved toward said anvil member so as to make it possible to clamp together therebetween said end region on said first vessel and an edge region on said second vessel, and d) stapling plungers longitudinally moveable relative to said first and second elongate members and adapted to insert staples penetratingly through said clamped end and edge regions into engagement with said stapling-bending recesses so as to bend permanently said staples into a shape, in which they hold said end and edge regions together.
Advantageoous embodiments of the anastomotic instrument according to the invention, the effects of which - beyond what is self-evident - are explained in the following detailed part of the present description.
A method is disclosed in EP-A-X54,990, Fig. 8, where an end-to-side anastomosis 14 - 15' is performed.
Fig. 8 of this document shows an end-14-to-side-15' ana-stomosis, but here suture 21 is used instead of clamping by moving parts, and a separate instrument 32 is used for the stapling action, i.e. not parts moving longitu-dinally in or around anvel 10.
Thus, it will be evident that the method and apparatus as described in EP-A-554,990 do not anticipate the method and apparatus of the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
In the following detailed part of the present description, the invention will be explained in more detail with reference to the exemplary embodiments of an anastomotic instrument according to the invention shown in the drawings, in which Figures 1-8 show the process of performing an end-to side anastomosis using an anastomotic instrument according to the invention, in Figures 1-7 being drawn in a highly simplified manner for ease of understanding, Figures 9-12 in perspective and with certain parts cut away show a practical embodiment of an anastomotic instru-- 4a -merit with the various possible relative positions of the relatively movable parts, and Figure 13 at a highly enlarged scale shows a part of the instrument shown in Figure 1 with modified clamping surfaces.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
As mentioned above, the embodiment shown in Figures 1-8 of the anastomosis instrument according to the present invention constitutes a simplified version with the primary purpose of explaining the invention; this does ~Myl~ ~D SaF_rs not, however, preclude the possibility of using this embodiment in actual practice.
Thus, Figure 1 shows an anastomosis instrument 1 5 consi:~ting of three main components that are movable relat:ive to each other in the longitudinal direction, i.e. :in the direction shown as the vertical direction in Figures 1:
- an anvil tube 2, - a clamping tube 5, and - a sect of stapling plungers 6.
On it~~ lower end, the anvil tube 2 carries an anvil 3 , the upper side of which is provided with a number of staple-bending recesses 4 adapted to cooperate with and bend an equal number of staples 7, in the situation shown in Figure 1 being temporarily held lightly in an equal number of staple-holding recesses 8 formed in the lower ends of the st=apling plungers 6.
Figure 2 shows the situation, in which the instrument is made ready for use by the operating surgeon. As mentioned initially, the anastomosis instrument according to the present invention is primarily developed for use when performing coronary bypass operations, and to this end, a bypass vessel 9 - that may be a vein taken from some other part of the patient's body - has been inserted in the anvil tube with its lower end evened about the anvil 3 and with its end region 10 covering the staple-bending :30 reces ses 4 in the upper surface of the anvil 3. At this point it should be noted that the bypass vessel 9 may have a considerably larger circumference than the inside of the anvil tube 2, consequently lying more or less folded in the longitudinal direction in the latter, for which reason the action of everting its end region 10 about. the anvil 3 does not necessarily entail undue stretching of the bypass vessel 9.
Figure 3 shows the instrument having been made ready as shown in Figure 2 inserted in an opening in a coronary artery 11, said opening having an edge region 12 which, due to the elasticity of the tissue of the coronary artery 11, will embrace the anvil tube 2 in a location close to the anvil 3. The opening in the coronary artery 11 may e.g. have been formed according to the method described in the international application with publication No. WO
95/17127 with the title "Method and instrument for establishing the receiving side of a coronary artery bypass graft".
As soon as the operating surgeon in the situation shown in Figure 3 has ascertained that the edge region 12 embraces the anvil tube 2 closely on all sides, he or she will proceed to the situation shown in Figure 4, in which the clamping tube 5 has been moved towards the anvil 3 so as to clamp the edge region 12 on the coronary artery 11 and the end region 10 on the bypass vessel 9 firmly together in readiness for the next step shown in Figure 5, in which the stapling plungers 6 have been moved downwardly so as to cause the staples 7 to penetrate the edge region 12 and the end region 10 and engage the staple-bending recesses 4, by which they will be bent in a tangential direction in a similar manner as is known from both surgical staplers and ordinary office staplers.
In the situation shown in Figure 6, the clamping tube 5 together with the stapling plungers 6 have been moved outwardly and away from the staples 7, the staple-holding WO 97/1b122 PCT/DK95/00430 recesses 8 due to their light holding action having let go of the staples 7, the latter also having been anchored in the end region 10 by their bent ends.
Figure 7 shows the situation, in which the operation of removing the anastomosis instrument 1 from the coronary artery 11 and its anastomosis with the bypass vessel 9 has begun. As will be seen from Figures 6 and 7, the circumferential pocket formed by the eversion of the lower end of the bypass vessel 9 will now open and allow the anvil 3 to be removed by luxation, Figure 8 showing the situation after such removal, resulting in a finished anastomosis of the intima-to-intima type considered most desirable for this type of operation.
The three main components of the anastomosis instrument 1 referred to above, i.e. the anvil tube 2, the clamping tube 5 and the set of stapling plungers 6, will, of course, have to be connected to some kind of operating members to enable the operating surgeon and his or her assistants to carry out the steps shown in Figures 1-8.
Theoretically, these operating members could consist of three tubes (not shown), viz.
- a relatively long holding tube in continuation of the anvil tube 2, - a somewhat shorter clamping tube in continuation of the clamping tube 5, and - an even shorter stapling tube, to which the stapling plungers 6 are connected.
As is well-known, however, coronary bypass operations, especially according to the method of the international application referred to above, should be carried out as rapidly as possible, and for this reason, the "theoretical" embodiment shown in Figures 1-7 is too cumbersome to work with to ensure a sufficiently rapid operating procedure. As mentioned above, Figures 9-12 illustrate an embodiment of an anastomosis instrument according to the present invention, that is highly suitable for creating' an end-to-side anastomosis in a very ;short time .
Due to the construction of the instrument shown in Figures 9-12 :it is not possible to make an easily understandable drawing in the nature of the simple drawings of Figures 1-7. F~'or this reason, the "active" parts of the instrument have been shown in perspective, and with the exception of the anvil and its supporting columns, with one half removESd along a longitudinal sectional plane, so that the remaining half can be seen partly from the inside, partly from the outside. In Figures 9-12, those of the components functionally corresponding to components shown in Figures 1-7 have been given the same reference numbers with :100 added, whereas components not having "opposite numbers" in Figures 1-7 have been given the reference numbers of the components, with which they are most closely associated, with the addition of a capital letter.
As shown in Figure 9, the anastomosis instrument 101 comprises a number of parts functionally corresponding to parts of the instrument shown in Figures 1-7, viz.:
- an anvil tube 102, - an anvil 103, - a clamping tube 105, and :30 - a set of stapling plungers 106.
Although the basic functions of these parts are the same as the basic functions of the corresponding parts in the embodiment of Figures 1-7, the arrangement differs somewhat from that of the latter, as will be evident from t:he following.
In contrast to the anvil tube 2 of Figure 1, the anvil tube 102 of Figure 9 extends on the outside of the instrument and is terminated by an end wall 102A, to which the anvil 103 is secured at a distance by means of two columns, viz . an upstream column 103A and a downstream column 103B. The expressions "upstream" and "downstream"
l0 refer to the direction of blood flow in the artery, in which the instrument 101 is intended to be used in creating an end-to-side anastomosis.
To make it possible to insert the bypass vessel (not shown) corresponding to the bypass vessel 9 shown in Figures 1-8, all transversely oriented components have suitax>le openings, of which the forwardmost opening 103C
is formed in the anvil 103, the latter being provided with staple-bending recesses 104 having the same function as the: staple-bending recesses 4 shown in Figure 1.
As will be seen from Figures 9-12, the various components are not rotationally symmetrical about the longitudinal axis of the instrument, as the anvil 103 has been made "boat-shaped" to make it easier to insert it in the opening in the artery and to make it easier for the edges of the opening to fit in with the upper side of the anvil 103 with the stapling recesses 104.
Due to the arrangement of the anvil tube 102 as the outermost component terminated by the end wall 102A, it is not. possible in this embodiment to let the clamping tube :L05 extend in its full circumferential width all the way towards the upper face of the anvil 103. For this reason, the clamping tube 105 is terminated by an end wall 105A, from which a set of clamping columns 105B
extend in the forward (downward) direction through suitable openings in the anvil tube end wall 102A.

The stapling plungers 106 are guided in the longitudinal direction in suitable guides in the clamping columns 1058, and their rearmost (uppermost) ends are secured to a stapling plunger carrier 106A, itself secured to and 10 terminating a stapling tube 1068, through which the force for actuating the stapling plungers 106 may be transmitted from a suitable operating device. Figures 9-12 show neither staples corresponding to the staples 7 of Figure 1 nor staple-holding recesses corresponding to the staple-holding recesses 8 shown in Figure 1, but it will be understood that the forwardmost (lowermost) ends of the stapling plungers 106 will be provided with suitable staple-holding recesses capable of holding staples in such a position, that when the stapling plungers 106 are advanced towards the anvil 103, the staples will be bent by the staple-bending recesses 104 in the usual manner.
The relative positions of the various parts as shown in Figure 9 correspond to those shown in Figures 1-3, i.e.
there is a sufficient distance between the rearward (upper) face of the anvil 103 and the forward (downward) ends of the clamping columns 1058 to accomodate the everted end region of the bypass vessel corresponding to the end region 10 shown in Figure 2, as well as the edge region of the coronary artery concerned corresponding to the edge region 12 of the coronary artery 11 shown in Figure 3.
The situation shown in Figure 10 corresponds to that shown in Figure 4, i.e. the clamping columns 105B have been advanced towards the anvil 103, in Figure 10 leaving a gap symbolizing the presence of the end region of the bypass vessel and the edge region of the coronary artery (all not shown). The movement of the clamping columns 1058 has, of course, been effected by advancing the clamping tube 105 to the same extent. To prevent said end and edge regions being crushed in the clamping operation, suitable stops (not shown) are adapted to stop the movement of the clamping columns 105B towards the anvil 103 so as to leave a gap just sufficient to hold them firmly together. To improve the grip, the clamping surfaces may be provided with elastically flexible fins or fingers 13 as shown in Figure 13. This Figure shows how this concept could be applied to the embodiment shown in Figures 1-7, it being - of course -equally applicable to that shown in Figures 9-12.
The relative positions shown in Figure 11 correspond to those shown in Figure 5, i.e. the stapling plungers 106 have now been advanced, guided by the clamping columns 105B so as to bring the staples (not shown) into engage-ment with the staple-bending recesses 104, thus joining the end region of the bypass vessel to the edge region of the coronary artery (a11 not shown).
The relative positions shown in Figure 12 correspond to those shown in Figures 6 and 7 and with the exception that in Figure 12, the stapling plungers 106 have not only been withdrawn from the staples joining the two vessels, but have in fact been removed completely from the instrument to make it possible to insert a new set of staples, that may be of the disposable or semi-disposable type.

y With the arrangement shown in Figures 9-12, the operating surgeon may literally have a firm grip on the situation by holding the outermost component, i.e. the anvil tube 102, which is rigidly connected to the anvil 103 through the columns 103A and 103B, so that he or she will be able to move the anvil 103 with the everted end of the bypass vessel into the opening in the coronary artery by direct manual control, and - not least - by "direct mechanical feedback", as the rigid mechanical interconnec-tion between the anvil 103 and the anvil tube 102 enables the surgeon to "feel" whatever object is encountered by the anvil. Advantageously, the rearward (upper) part (not shown) of the instrument may comprise suitable operating devices and/or mechanisms for moving the clamping tube 105 and the stapling plungers 106 relatively to the anvil tube 102 and hence relatively to the anvil 103. Due to the extremely limited time available for performing coronary bypass operations, these operating devices and/or mechanisms should be designed to enable the operating surgeon to initiate the requisite movements rapidly and with a minimum of effort.
Thus, the operating devices and/or mechanisms could be arranged to function under the control of a single operating member, such as a push-button on the rear (upper) end of the instrument adapted to be operated by the surgeon's thumb, in the following manner:
- firstly, when the operating member is moved in a first direction, e.g. a push-button is depressed, the clamping columns 105B will be advanced to their forwardmost (lower) position, in which they clamp the end region of the bypass vessel and the edge region of the opening in the artery together until said stop is reached, and then the stapling plungers 106 will immediately be A~.~~l'1~~~ s~'~'~
actuated to staple the two regions together, after which both the clamping columns 105B and the stapling plungers 106 are withdrawn, e.g. by releasing said push-button, and - secondly, immediately upon the operating member moving in the opposite directian, e.g. when the push-button has been released, the mechanism is re-set in readiness for a movement in the first direction, after which the instrument can be removed as described above with reference to Figure 7.
It should be possible for a technician skilled in the art of designing and making surgical instruments comprising operating mechanisms to design and construct an operating device or mechanism capable of operating in the manner described above, for which reason these parts have not been described or shown in detail.
