Description

CA 0220~636 1997-0~-30 SETTING TOOL FOR A FASTENING PIN

The present invention relates to a setting tool for inserting a fastening pin for fixing a covering membrane to a defective bone area filled with reconstructive bone material with surrounding endogenous bone.
It is common practice, for example in the field of oral surgery, to fill defective areas in an endogenous bone with a bone substitute or reconstructive material which consists of, for example, hydroxylapatite granules, possibly mixed with endogenous bone granules. The defective area filled with the reconstructive bone material is then covered with a covering membrane made of a biologically compatible synthetic material or the like which adjoins the endogenous bone adjacent to the defective area, so that the reconstructive bone material is ossified by the endogenous bone. Should other types of connective tissue, in particular mucous tissue, grow through the substitute bone material, the defective bone area would not be satisfactorily filled with regrowing bone material.
It has hitherto been difficult to securely and tightly fasten the covering membrane about the defective area on the endogenous bone, and accordingly, undesired growth of non-bone tissue into the defective bone area has not been avoidable with sufficient reliability.
An object of the present invention is to provide a setting tool for inserting a fastening pin, by which it is possible to connect a covering membrane securely and tightly, in a simple manner, with the endogenous or body bone, so that it can be assured that the reconstructive bone material is grown through only, or at least to a great extent, with bone tissue.
Accordingly, the present invention provides a setting tool for inserting a fastening pin for securing a covering membrane to a defective bone area filled with reconstructive bone material with surrounding endogenous bone, said tool comprising an elongated pencil-type handle, on one end of which is provided a pressure/striking head CA 0220~636 1997-0~-30 and on the other end of which is provided a holder for a fastening pin, having at least two resilient clamping jaws.
The fastening pin forms the subject matter of copending application No. 2,112,755, filed January 4, 1994, of which the present application is a divisional.
The parent application defines a fastening pin for securing a covering membrane to a defective bone area filled with reconstructive bone material with surrounding endogenous bone, said pin comprising an enlarged diameter head capable of being acted upon by a pressure and/or striking tool, and a pin shaft adjacent the head of a smaller diameter and having a generally cylindrical holder and, adjacent thereto, a portion essentially tapering to a point, wherein the transitional area between the holder and the pointed portion has an annular shoulder of a larger diameter than the holder, which shoulder extends towards the point of the pin with a conical surface diagonally into the surface of the pointed portion and adjoins the holder in a barb-like manner with an annular surface extending essentially at right angles to the longitudinal axis of the fastening pin.
The conical surface of the annular shoulder of the fastening pin extends from the outer periphery of the annular surface to the surface of the point without any essential change in conicity. The conical surface of the annular shoulder may also comprise a larger angle with the longitudinal axis of the fastening pin than the area of the surface of the point adjoining it.
In a further embodiment of the fastening pin, the angle between the conical surface of the annular shoulder and the longitudinal axis of the fastening pin is approximately 25~.
Furthermore, the fastening pin can be constructed in such a way that the surface of the holder smoothly transitions, by way of a slope, into the pressure surface of the pinhead extending essentially at right angles to the longitudinal axis of the fastening pin.

CA 0220~636 1997-0~-30 Alternatively, the head of the pin has, on its periphery adjoining the pressing surface, a peripheral slope increasing from it in direction of the top surface of the pin facing away from the pin shaft.
In addition, the head surface of the pinhead is rounded. Titanium alloy(s) or the like are suitable for use as a manufacturing material for the pin.
The setting tool of the present invention for inserting the fastening pin comprises an elongated pencil-type handle, on one end of which a pressure/striking head is provided and on the other end of which a holder for a fastening pin, having at least two clamping jaws, is provided. In one embodiment, the holder has four clamping jaws separated by a cross-slotted arrangement.
The invention further provides for the jaws to be made in one-piece with the area of the surface of the handle adjacent thereto.
The invention also proposes that the clamping jaws each have a contact shoulder for the head surface of the fastening pin, whose distance from the face end of the holder, facing away from the handle, is less than the height of the head of the pin.
A further embodiment of the setting tool of the invention is characterized by an auxiliary setting tool independent of the handle, having a handle, a fixing part adjacent thereto which has a hold-down foot which is provided with a set opening and which can be brought to rest against the bone, the diameter of which opening is slightly larger than the outside diameter of the holder.
A drill template is provided which can be longitudinally displaced in the fixing part, and is made of a flexible sheet metal or the like. The template has a borehole on its end adjoining the set opening and can be retracted from a bore position in which the set opening is closed, with the exception of the borehole, into a set position in which the set opening is uncovered.

CA 0220~636 1997-0~-30 It can thereby be provided that the hold-down foot has at least two pointed retaining pegs on the bottom side to be placed against the bone.
The invention also proposes that a retaining peg be provided on each of the two diametrically opposite sides of the set opening.
In another embodiment of the invention, the drill template is provided with a control element in the vicinity of the handle which can be controlled by a surgeon without releasing the handle.
The invention is based on the surprising discovery that it is possible to solve problems which occurred previously when covering defective areas filled with a reconstructive bone material, by providing a covering membrane fastened to the body bone around the defective area by means of a fastening pin which, due to its barb-like construction, ensures that the covering membrane is pressed tightly against the endogenous bone. In the preferred embodiment of the setting tool of the invention in which an auxiliary setting tool is used, the covering membrane can first be accurately and firmly fixed to the bone with the help of the auxiliary setting tool by laterally securing it in position by means of the retaining pegs of the foot of the auxiliary setting tool. After a set bore has been inserted which is in exactly the centre of the set opening, a fastening pin can be accurately, and without lateral displacement, inserted into the set bore and deeply and firmly into the bone, after the drill template is withdrawn through the set opening by means of the setting tool, as a result of which the covering membrane is reliably and tightly fixed to the bone.
The invention will be more readily understood from the following description of a preferred embodiment thereof given, by way of example, with reference to the accompanying drawings, in which:

CA 0220~636 1997-0~-30 Figure 1 shows an embodiment of a setting tool of the invention in connection with an embodiment of a fastening pin, shown in exploded position;
Figure 2 shows a holder for the setting tool of Figure 1, in axial longitudinal section with fastening pin held therein;
Figure 3 is an axial longitudinal sectional view of the fastening pin of Figure 1 and Figure 2 on an enlarged scale;
Figure 4 shows a further embodiment of a setting tool according to the invention with auxiliary insertion tool, in axial longitudinal section;
Figure 5 is a top view of the auxiliary insertion tool of the setting tool of Figure 4;
Figure 6a shows the hold-down foot of the auxiliary insertion tool of Figure 5, in an enlarged detail drawing, also in a top view;
Figure 6b shows a section along the line VIb - VIb of Figure 6a, seen in direction of the arrows;
Figure 7a shows the hold-down foot of the auxiliary insertion tool of Figure 5 with drill template advanced into the drill position; and Figure 7b shows a section along the line VIIb -VIIb of Figure 7a, seen in direction of the arrows.
As can be seen in Figure 1, the embodiment shown there of a setting tool 10 according to the invention has an elongated, "pencil-type" handle 12, on the end of which, shown at the top in the drawing, a pressure/striking head 14 is provided for striking with e.g. a hammer. On the end of the setting tool 10, opposite the pressure/striking head 14, is a holder 16 which has four clamping jaws 18, 20, as can be better seen in the enlarged illustration of Figure 2, which are separated from one another by a cross-slotted arrangement 22 and which project spring-like from the handle 12. The jaws 18, 20 are provided with contact shoulders 24, 26 on their front ends, facing away from the handle 12.

CA 0220~636 l997-0~-30 A head 28 of a fastening pin 30, which will be described in greater detail with reference to Figure 3, has a pressure surface 32 and a head surface 34. The distance between the pressure surface 32 and the "highest" point of 5 the head surface 34, as seen in the axial direction, is greater than the distance between the contact shoulders 24, 26 and the front end of the clamping jaws 18, 20.
As can be seen in Figure 3, the illustrated embodiment of the fastening pin 30 has, in addition to the already mentioned head 28 provided with head surface 34 and pressure surface 32, a pin shaft 36 which consists of an essentially cylindrical holder 38 and an integrally formed pointed portion 40, shown at the bottom in the drawing. An annular shoulder 42 iS provided between the holder 38 and 15 the pointed portion 40. The annular shoulder 42 passes over into the covering surface of the holder 38 with an annular surface 44 essentially at right angles to the longitudinal axis of the fastening pin 30. A conical surface 46 adjoins the annular surface 44 in direction of the tip of the pin, the angle of said conical surface being 25~ with respect to the longitudinal axis of the fastening pin. This angle is greater than the angle which the covering surface 48 of the pointed portion 40 forms with the longitudinal axis of the fastening pin.
The surface of the holder 38 of the fastening pin 30 merges with the pressure surface 32 of the head 28 of the pin through a sloped or bevelled portion 50. A
peripheral slope 52 ascends from the pressure surface 32 of the head 28 of the pin to its largest outer periphery.
The entire pin is made of a biologically compatible material such as titanium alloy.
In the embodiment shown in Figure 4, the setting tool has an auxiliary insertion tool 54 which consists essentially of a handle 56 and a fixing part 58. The 35 fixing part 58 has a hold-down foot 60 which is provided with a set opening 62 on both sides of which two retaining pegs 64, 66 are arranged diametrically opposite each other, CA 0220~636 l997-0~-30 as shown more clearly in Figures 6 and 7. A drill template 68, formed of flexible sheet metal, has a borehole 70 on its end facing away from the handle 56 and a control element 72 on its end facing the handle 56.
In the simplest cases, if it is not necessary to first insert a set bore into the endogenous fixed bone, a fastening pin 30 iS inserted into the holder 16 of the setting tool 10 in the form seen in Figure 2. The clamping jaws 18, 20 thereby hold the head 28 of the pin in a spring-like manner, whereby the head surface 34 adjoins the contact shoulders 24, 26 of the clamping jaws 18, 20. Due to the dimensioning, which was described above, the pressure surface 32 of the fastening pin 30 iS in front of the front ends of the clamping jaws 18, 20, seen from the 15 "direction of the bone", as can be clearly seen in Figure 2. The handle 12 of the setting tool 10 is gripped with the hand by the surgeon, after which the fastening pin 30 is pressed into the bone or driven into the bone with aid of a hammer hitting the pressure/striklng head 14. As a 20 result of this, the covering membrane lying on the bone is firmly clamped between the pressure surface 32 of the head 28 of the pin and the bone surface adjacent thereto, whereby the slope 50 prevents undesirable mucous residues or the like from collecting in a "blind spot". Due to the 25 tight fit of the covering membrane on the bone, which is not shown, soft connective tissue, in particular mucous tissue, is prevented from penetrating and growing into the defective area of the bone which is covered by the covering membrane and filled with substitute bone material, as a 30 result of which ossification of the bone substitute or reconstructive material is assured. The contact shoulder 42, which is barb-like, thereby assures a firm fit of the fastening pin 30 in the bone. The peripheral slope 52 makes it possible to again remove the fastening pin 30 from 35 the bone, if desired, by using forceps or the like.
Generally, the endogenous bone is sufficiently hard enough however, that the fastening pin 30 cannot be CA 0220~636 l997-0~-30 inserted into the bone without first providing a setting bore or hole. The process proceeds such that the covering membrane is pressed against the bone by means of the auxiliary setting tool 54 shown in Figures 4 to 7, whereby 5 the retaining pegs 64, 66 fix the membrane at predetermined points, so that it cannot shift. The hold-down foot 60 of the auxiliary setting tool 54 thereby lies flat against the bone or the covering membrane covering it. When the drill template 68 iS advanced, that is, whereby the set opening 10 62 iS completely sealed with the exception of the hole 70 (Figure 7), a set bore is inserted into the bone through the borehole 70 by means of a drill 74. The drill 74 iS
then pulled out and the drill template 68 pulled back without it being necessary to lift the hold-down foot 60 15 from the endogenous bone covered with the covering membrane. The fastening pin 30 iS then inserted into the set bore through the set opening 62 (which is now open) by means of the setting tool 10, the handle 12 of which is held by the surgeon with his free hand. The diameter of 20 the setting hole is thereby selected in such a way that it corresponds approximately to the outside diameter of the holder 38 for the fastening pin 30, yet is smaller than the outside diameter of the annular shoulder 42, SO that the latter can exert its barb-like retaining function.
