Main St, Wilmington, ()hio Filed Nov. 2, 1362, er. No. 23$,tl12 i @iairns. (Ci. 128-3ti5) This invention relates to novel methods and surgical instruments useful in performing tracheotomies.
The methods and instruments of this invention facilitate the provision of an opening in a patients trachea to receive a trachea tube. Although the methods and instruments are not so limited, they are especially useful under emergency conditions, particularly where professional medical assistance is not available.
A number of methods and devices exist for use in preparing a patients trachea for receiving a trachea tube. In accordance with all of those methods it is necessary to provide an incision or opening in the trachea itself, into which the trachea tube may be inserted. The methods and devices of this invention facilitate the very rapid preparation of an incision suitable for reception of a trachea tube by permitting easy removal of a portion of the tracheal tissue, including portions of the tracheal rings or cartilage.
In performing a tracheotomy it is first necessary to expose the trachea itself. That is generally done by making a transverse incision in the patients neck intermediate the third and fourth cartilage rings. The edges of the tissue adjacent the incision are then spread so that the trachea itself is visible.
The preparation of the opening in the trachea can be very ditficult at times, particularly where a portion of the trachea is to be removed. Under such circumstances great care must be exercised to anchor the tracheal rings or to hold them in a predetermined position while a portion of the tracheal tissue is being removed. And frequently when a portion of the tracheal tissue, such as portions of the tracheal rings, has been but partially severed, the areas from which the portion is being cut out may become covered with blood and foam and the face of the operator may become sprayed with blood, mucus and foam, thereby hampering his vision. That is particularly a problem under emergency circumstances where facilities for keeping areas upon which operations are being performed cleared of blood, mucus, and the like, are not available.
Difiiculties may also be encountered in removing tracheal tissue from a patients neck where the patients trachea is located deep within his neck. Similarly, difficulties in preparing an opening in a patients trachea may be encountered when the trachea, as it extends inferiorly in the neck, is directed rapidly posteriorly. In such cases, particularly under emergency conditions, it is extremely hard to perform a safe and rapid tracheotorny.
With the methods and instruments of this invention the foregoing hardships are minimized and in many cases eliminated.
Therefore it is a principal object of this invention to provide novel and simple methods and surgical instruments for performing a tracheotomy.
It is another principal object of this invention to provide novel and simple methods and surgical instruments for removing a segment of tracheal tissue from a patients trachea preparatory to inserting a trachea tube.
Also an object within the contemplation of this invention is the provision of a novel surgical punch especially adapted for removing a segment of tracheal tissue.
Yet another object of this invention is the provision of a novel surgical punch, a portion of which is designed to be inserted into a trachea through a slit therein and which portion is adapted to cooperate with another portion of the punch located exteriorly of the trachea to remove and to retain a segment of tracheal tissue.
In accordance with this invention once the trachea has been exposed in any conventional manner, a transverse slit is made in the trachea, preferably between the third and fourth cartilage rings. As will be described in greater detail, a button end of the tracheal punch is first pushed through the slit superiorily and is then depressed inferiorly. That places the button end completely within the trachea. A cooperating portion of the trachea punch of this invention is then pushed towards the trachea and the button end, sufficient force being exerted so that the sharpened cutting segment of the cooperating portion of the punch cuts through the trachea. end and sharpened portion move into an overlapping relationship, a disc shaped opening in the trachea is provided. The tracheal tissue, that is the portions of the third and fourth cartilage rings and the adjacent tissue, is trapped within the punch, thereby eliminating the possibility and danger of their being lost in the trachea itself. The opening in the trachea having been thus prepared, the trachea tube maybe inserted in a routine manner.
Thus it will be appreciated that the punch and the method of using it are. quite simple but very effective.
Further objects and advantages of this invention will become apparent from the following description and drawings of which:
FIGURE 1 is a side elevation of a trachea punch of this invention;
FIG. 2 is a side view partially in section of the trachea punch of FIG. 1;
FIG. 3 is a side view, partially in section, of the trachea punch of FIG. 1 showing the punch element in its fully retracted position;
FIG. 4 shows a patient having had a transverse slit made in the trachea in accordance with the method of this invention;
FIG. 5 shows how the button end of the trachea punch is inserted into the slit in the trachea;
FIG. 6 shows the trachea punch with the button end fully inserted in the trachea;
FIG. 7 shows the sinuous cutting edge as it begins to sever the tracheal tissue; and
FIG. 8 shows the opening which has been provided in the trachea by the trachea punch.
FIGS. 1 to 3 illustrate a presently preferred embodiment of the trachea punch of our invention. The trachea punch 1 there shown consists of two main elements, the body 10 and the punch element 12.
Body 10 comprises a generally elongated cylindrical hollow housing 14 having an opening 16 adjacent its upper end. A head '18 is connected to the upper end of housing 14 and has a generally convex top 20 of a diameter somewhat greater than the diameter of housing 14. At two diametrically opposed locations head 18 is provided with chamfered segments 21 to facilitate gripping head 18 and to prevent its rotation when in use.
Head 18 at its lower surface terminates in a shaft 22 having a reduceddiameter segment 24 of substantially the same diameter as the inside diameter of housing 14. Reduced diameter segment 24 has a tapped hole 26 adapted to receive a lock bolt 28 when reduced diameter segment 24 resides in housing 14. An annular shoulder 30 at the base of shaft 22 limits the extent to which reduced diameter segment 24 of head 18 may be inserted inwardly of housing 14.
When tapped hole 26 is aligned with opening 16, lock bolt 28 may be screwed into tapped hole 26 to lock head 18 to housing 14.
When the button At the end opposite the endto which head 18 is connected, housing 14 terminates in la sharpened sinuous cutting edge 32, the purpose of which will become apparent. Completing the structure of housing 14 are two diametrically opposed longitudinally disposed slots 34 communicating with the interior and with the exterior of the housing.
Although we do not intend to be so limited, housing 14- may be fabricated of norumagnetic stainless steel and head 13 of aluminum. So also may punch element 12 be fabricated of non-magnetic stainless steel.
Referring now to FIGS. 2 and 3, punch element 12 is seen to include an upper cylindrical guide portion 36. A first hole 38, circular in cross section, is provided therein. An axially disposed tapped hole :0, communicating with hole 38 and with the upper end 42 of guide portion 35 is adapted to receive a set screw for a purpose to be described.
The other end of guide portion 36 of punch element 12 terminates in a truncated conical segment 4-6. Guide portion 36 is sufiiciently long so that When the punch element is in its fully extended position, the truncated conical segment 46 is disposed entirely outside of housing 14- thereby largely preventing accidental cutting by the sinuous cutting edge 32. Extending downwardly from the truncated conical segment is an elongated cylindrical button carrying shaft 4S, circular in cross section. A button 59 is provided at the end of button carrying shaft 48. Button is itself circular in cross section throughout and comprises a cylindrical segment 52 of uniform diameter and a rounded convex end 54' in which it terminates. The diameter and the peripheral dimensions of the cylindrical segment 52 are substantially identical to those of housing 14 adjacent sinuous cutting edge 32. It will be appreciated therefore that edge se of button 5-6 and sinuous cutting edge 32 are adapted to cooperate to cut tissue when tissue is interposed between them and they are drawn together into an overlapping relationship in the manner which will be described.
Punch element 12 also includes a bar 58 removably connected thereto. The dimensions of bar 58 are such that it is slidably received by hole 38 in which hole it is locked by set screw 44. Longitudinal slots 34 are also dimensioned so that they will slidingly receive bar 58.
To assemble trachea punch l, punch element 12. is inserted into housing 14. Then bar 53 is passed through one of the longitudinal slots 34, through hole 38 in guide portion 36 of punch element 12, then outwardly through the other longitudinal slot 34. When bar 58 has been properly centered with respect to punch element 12 and housing 14, set screw 44 is tightened thereagainst. Then the reduced diameter segment 24 of head 1% is disposed inwardly of the upper end of housing 14, opening 16 and tapped hole as are aligned, and lock bolt 28 is inserted and tightened to maintain the connection between head 18 and housing 14.
The peripheral dimensions of guide portion 36 and the internal peripheral dimensions of housing 14 have been predetermined to very close tolerances so that upon reciprocation of one part with respect to the other, sliding movement with substantially no wobble is obtained. Thus guide portion-36 serves to guide punch element 12 as it reciprooates within housing 14-. The same close tolerances exist between the cylindrical segment 52 of button 5% and the inside of housing 14 adjacent the sinuous cutting edge 32, thereby providing an effective cutting means similar in operation to a punch and die.
Punch element 12 is proportioned with respect to longitudinal slots 34- and housing 14- so that button 519 may extend forwardly and outwardly of cutting edge 32 about one inch. Those elements have also been proportioned so that button 5% may be drawn completely inwardly of housing 14 as is best seen in Fifi. 3,-into an overlapping relationship. That is the instruments retracted position.
The overall size of the trachea punch is not critical.
In one embodiment, one particularly useful for adults, in
its extended position, the trachea punch is about 4 /2 inches long. In its retracted position, that is with button 59 lying completely within housing 1- 2, the instrument is approximately 3% inches long. It is possible, and also desirable, to use a trachea punch which is of somewhat smaller dimensions for children and for babies. The most suitable dimensions and the most suitable size of the segment to be removed from the trachea of a given patient will depend upon many factors, all of which will be apparent to those of ordinary skill in the art in View of the description herein given.
An un erstanding of the method of this invention and the manner in which the trachea punch of this invention is used will be facilitated by referring to FIGS. 4 to 8 particularly.
FEGURE 4 shows a patient whose trachea has first been exposed in a conventional manner. Then a transverse slit S is made in the trachea, preferably between the third and fourth cartilage rings with a scalpel-such longer than the diameter of the cylindrical segment 52 of button 5%} of the trachea punch to be used for prepar ing the opening.
As shown in FIG. 5, button 59 of the trachea punch is inserted into the trachea through slit S. The button is held in its extended position by the operators thumb and index finger, the housing being held back by the operators grip upon head 13. Then, much like one inserts a button on a shirt into a button-hole, one side of;
button 5% is inserted into slit S.
The inserted segment of'button 50 is then disposed against the inside of the trachea adjacent the slit, thereby 1 serving as a fulcrum so that as the operator moves his hand downwardly as indicated by the arrow in FIG. 5, the convex top 54 pushes against the outer lower side of slit S until the entire button 5t is forced into the trachea. With the insertion having thus been completed,
as best seen in FIG. 6, the punch is positioned to remove the desired segment of tracheal tissue.
By placing his third and fourth fingers beneath bar 58; as best seen in FIG. 7, and by squeezing downwardly upon head 13 the operator causes sinuous cutting edge 32 to contact and penetrate the tracheal tissue surrounding slit S. Edge 56 of button 5%) cooperates with sinuous cutting edge 32 as edge 32- completes its penetration of the trachea and its severance of the tracheal tissue.
Finally edge 55 and button 5% are disposed inwardly of housing 14 as is illustrated in FIGS. 3 and 8. In that manner the tracheal tissue severed is retained within the housing, between the inside wall of housing 14, button 50 and truncated conical segment 46.
The tracheal segment removed is generally disc-like in shape as can be appreciated from FIG. 8 which shows the opening 0 provided in the trachea in accordance As shown in FIG;
with the method of this invention.
8, the trachea is ready for the insertion of the trachea tube. I
Both the instruments and the methods of this inventionhave been exemplified by the presently preferred embcdi-meuts thereof. Both provide new and extremely useful tools for the medical profession.
