Description
INSTRUMENT FOR MANIPULATING A SURGICAL STAPLE AND METHOD
FOR PRODUCING THIS INSTRUMENT
The present invention relates to an instrument for manipulating a surgical staple, and a method for producing this instrument. In the surgery field, the use of staples to hold two tissues, particularly in performing osteosynthesis, is well known. These staples are generally made of a shape-memory metallic material, also called "hyperelastic", or may be made of a resorptive material.
This type of staple often comprises two lateral branches which, when the staple is in its undistorted state, are in a first position in which they converge toward each other in the direction of their free ends, and which, when the staple is in its elastically distorted shape, are in a second position in which they are parallel to each other.
The staple is implanted in the two tissues to be joined together, in particular by impaction when these tissues are bones, while its lateral branches are in said second position; the return of these lateral branches to said first position makes it possible to press the two tissues against each other.
To manipulate the existing staples, there are instruments forming staple grippers which make it possible, by sliding staples on a part forming a cam comprised by these grippers, to spread the lateral branches of the staple apart in order to bring these lateral branches into said second position, then to implant and release the staples.
These existing instruments are not, however, fully satisfactory, being relatively complex and expensive to manufacture. Since they may only be used one time, they must be sterilized after each use.
The present invention aims to resolve these essential drawbacks. To this end, the instrument in concerns comprises:
- a first part comprising, at one end, a transverse groove for receiving the central branch of a staple, adjusted to the shape of this central branch, and
- a second part comprising a curved end, having a size slightly greater than the distance between the inside edges of the two lateral branches of a staple at the point where these lateral branches are connected to the central branch of this staple, such that this curved end may be forcefully inserted between these two lateral branches and is able to maintain these two
branches in a position in which these lateral branches are parallel to each other, said second part of the instrument being mobile relative to said first part between a position maintaining a staple in the instrument, in which said curved end covers said groove in such a way as to tightly hug the central branch of the staple in said groove, and a position releasing the staple, in which said curved end is freed from said groove, thereby making it possible to release the staple from the instrument.
Thus, in the instrument according to the invention, the branches of the staple are maintained in the open position through the forceful insertion of said curved end between the two branches, and the staple is maintained relative to the instrument, or is released, through the cooperation or non-cooperation of the two parts of the instrument.
The instrument according to the invention may then have a simple structure, making its production relatively simple and inexpensive. This instrument may even be intended for one single use.
The instrument preferably comprises pivot means to make it possible for said second part to move relative to said first part by pivoting.
Advantageously, in this case, one of the two parts, preferably the second part, comprises an integral cylindrical boss, having an axis parallel to the pivot axis of said second part relative to said first part, and the other of said parts comprises a cylindrical recess intended to receive said boss snugly, with the possibility of pivoting this boss in this recess.
Said pivot means are simple to produce by conforming of said parts.
According to another possibility, the instrument comprises a deformable bridge connecting the two parts to each other, the deformation of this bridge allowing said second part to pivot relative to said first part.
The instrument according to the invention may thus be made of just one piece.
Said second part may comprise a branch extending on one side opposite said curved end relative to said pivot means.
This branch forms a lever which may be manually actuated to cause said second part to pivot with respect to said first part.
According to a preferred embodiment of the invention, said first part forms, from the side opposite its end comprising said groove, a resistant
portion able to withstand the necessary strike to implant the staple by impaction.
The instrument according to the invention thus not only enables manipulation of the staple, said resistant portion serving as a gripper, but also impaction of this staple.
Said first part or said second part may comprise two holes through it, the pitch of which corresponds to the pitch of the lateral branch of the staple at the point where these lateral branches are connected to the central branch of the staple. These two holes also enable the instrument to constitute a guide for piercing the bones, or other tissues, intended to receive the staple.
These holes may be aligned parallel to the axis of said first part or said second part, or perpendicular to this axis.
The method for producing an instrument according to the invention comprises steps consisting of:
- cutting a bar of material to individualize said first and second parts, and to develop a passage allowing the mobility of said first part relative to said second part,
- developing said groove in said first part thus formed. The instrument according to the invention may thus be obtained from a same bar, by simple cuts or machining making it possible to develop said first and second parts and said groove.
Advantageously, the material of this bar is sufficiently resistant so that the uncut part of this bar constitutes a resistant portion able to undergo the strike necessary for implantation of the staple by impaction.
The bar may, in particular, be made of a metallic or plastic material, according to the standards in force and manufacturing constraints, in particular molded in only one piece by injection.
The method according to the invention may also comprise a step consisting of developing, through said uncut part of this bar, two holes, the pitch of which corresponds to the pitch of the lateral branches of the staple at the point where these lateral branches are connected to the central branch of the staple.
The invention will be well understood, and other characteristics and advantages will appear, in reference to the annexed schematic drawing,
illustrating, as a non-exhaustive example, a preferred embodiment of the instrument it concerns.
Figure 1 is a side view, before placing a staple and assembling the two parts forming the instrument; Figure 2 is a view according to a direction perpendicular to the view in figure 1 ;
Figure 3 is a partial view, similar to figure 2, after placing a staple on it and assembling said parts;
Figure 4 is a similar view to figure 3, as a perspective view; Figure 5 is a view similar to figure 4, during placement of a staple in a bone;
Figure 6 is a side view after releasing the staple, and
Figure 7 is a view similar to figure 6, as a perspective view.
The figures illustrate an instrument 1 for manipulating an osteosynthesis staple 2, meaning making it possible to bring this staple 2 opposite its implantation site, impact this staple in order to place it in a bone 3 and release this staple 2 once it has been put into place.
The staple 2, known in itself, is made of a metallic shape-memory or
"hyperelastic" material, or perhaps a resorptive material. It comprises two lateral branches 2a and a central branch 2b. When the staple 2 is in its undistorted state, shown in figure 2, the lateral branches 2a are in a first position in which they converge toward each other in the direction of their free ends; when the staple 2 is in its elastically distorted state, shown in figures 3 and 4, these lateral branches 2a are in a second position in which they are parallel to each other.
As shown more specifically in figure 1 , the instrument 1 comprises a first part 5 and a second part 6. It appears in figures 4 and 5 that these two parts 5 and 6 were obtained by cutting a same square section bar, so as to individualize these parts 5 and 6. This bar is made of a resistant material, particularly a metallic material.
Said first part 5 comprises, on its side intended to receive a staple 2, a transverse groove 10, a cylindrical recess 11 and a recess 12 forming a passage. On its opposite side, the part 5 comprises an uncut portion 13, and comprises two holes 14 which passes right through this portion 13.
The transverse groove 10 is developed in the surface of the end of the part 5 and is sized to snugly receive the central branch 2b of a staple 2. This groove 10 is the same shape as the central branch of the staple.
The cylindrical recess 11 has an axis parallel to the groove 10 and is intended to receive, snugly but with the possibility of pivoting, a corresponding cylindrical boss 17 comprised by the part 6, such as to allow pivoting of this part 6 relative to the part 5, as shown by figures 6 and 7.
The passage formed by the recess 12 allows the part 6 to pivot between a position in which a staple 2 is kept in the instrument 1 (cf. figures 3 to 5) and a position releasing the staple 2 (cf. figures 6 and 7).
The portion 13, uncut, is resistant and able to undergo the strike necessary to implant the staple 2 in the bone 3 by impaction.
The two holes 14 have a pitch which corresponds to the pitch of the lateral branches 2a of the staple 2 at the point where these lateral branches 2a are connected to the central branch 2b, such that they allow the instrument 1 to also constitute a guide for piercing the bone 3 intended to receive the staple
2.
The second part 6 comprises, on the side of the instrument 1 intended to receive the staple 2, an end 15 forming a curved lip, a recess 16 forming a passage, the aforementioned cylindrical boss 17 and an actuating branch 18.
The end 15 has a size slightly greater than the distance separating the inner edges of the two lateral branches 2a of a staple 2 at the point where they are connected to the central branch 2b of this staple, such that this curved end 15 may be forcefully inserted between these two lateral branches 2a and can maintain these two branches in a position in which these lateral branches are parallel to each other, as shown in figures 3 and 4.
The passage formed by the recess 16 enables the engagement of the part 6 around the zone of the part 5 which delimits the groove 10, in order to make it possible for the part 6 to enter the aforementioned maintaining position. In this maintaining position, the end 15 covers said groove 10 so as to tightly hug the central branch 2b of the staple 2 in this groove 10.
The boss 17 becomes engaged in the corresponding recess 11 , in order to make it possible to guide the pivoting of the part 6 relative to the part 5.
The branch 18 extends on the side of the part 6 opposite the end 15 relative to the boss 17, and forms a lever able to be actuated manually to cause this part 6 to pivot relative to the part 5.
In practice, the lateral branches 2a are separated by a separate instrument comprising tilted walls forming a separation cam, then the central branch 2b of the staple 2 is inserted in the groove 10; the end 15 is then engaged closely between the lateral branches 2a at the same time as the boss
17 is engaged in the recess 11.
In this state of assembly, shown in figures 3 and 4, the instrument 1 forms a unit, the piece 6 being held in position thanks to the friction existing between its end 15 and the lateral branches 2a of the staple 2.
Thanks to the holes 14, the instrument may be used to pierce the bone 3 with pre-holes for receiving the lateral branches 2a, then, as shown in figure 5, the instrument may be used to impact the staple 2 in the bone 3, this impaction being done by striking on the portion 13.
Once the staple 2 is impacted in the bone 3, pressure is exerted on the branch 18 in such a way as to pivot the part 6 relative to the part 5 in order to bring this part 6 into its position releasing the staple 2 shown in figures 6 and 7. The instrument 1 may then be removed. As shown by the preceding, the invention provides an instrument 1 for manipulating a surgical staple having, relative to similar instruments of the prior art, the determining advantages of being relative simple and inexpensive to manufacture, and being able to be used only once while also being completely functional regarding the immobilization of the staple relative to it, impaction of this staple and release of this staple.
It goes without saying that the invention is not limited to the embodiment described above as an example, but that it extends to all embodiments covered by the annexed claims. In particular, the instrument may be made of just one piece and comprise a deformable bridge connecting its two parts to each other, the deformation of this bridge enabling said second part to pivot relative to said first part.
