Abstract

An instrumentarium for implanting a tendon replacement in a channel within a bone comprises a suture retention device. Said suture retention device has a plate-shaped body and a cylindrical pin projecting from said plate-shaped body. At least two openings extend through that plate-shaped body and said cylindrical pin for threading fixation threads of a tendon replacement therethrough. Said plate-shaped body having edges adapted for applying a tool for rotating said suture retention device (FIG. 13).

Claims

1. Instrumentarium for implanting a tendon replacement in a channel in a bone comprising

a suture retention device,

said suture retention device having a plate-shaped body with first and second sides,

a cylindrical pin projecting from the first side of said plate-shaped body;

a recess in the second side of said plate-shaded body for accommodating ends of fixation threads of a tendon replacement; and

at least two openings extending through said plate-shaped body and said cylindrical pin for threading of the fixation threads of the tendon replacement therethrough, wherein said recess verges into each opening via a plurality of curved surfaces, and

wherein said cylindrical pin being configured to come to snugly fit within a countersunk recess in a channel within a bone, an area of said plate-shaped body surrounding said cylindrical pin being configured to come to rest to a bone surface surrounding said countersunk recess in said bone, and wherein said plate-shaped body having edges adapted for applying a turning tool thereon for turning said device with said tool.

2. The instrumentarium of claim 1, wherein said plate-shaped body is provided with two opposite edges.

3. The instrumentarium of claim 1, wherein said cylindrical pin projects from a planar side of said plate-shaped body of said suture retention device.

4. Instrumentarium for implanting a tendon replacement in a channel in a bone comprising

a suture retention device,

said suture retention device having a plate-shaped body,

a cylindrical pin projecting from said plate-shaped body and

at least two openings extending through said plate-shaped body and said cylindrical pin for threading fixation threads of a tendon replacement therethrough wherein said cylindrical pin being configured to come to snugly fit within a countersunk recess in a channel within a bone, an area of said elate-shaped body surrounding said cylindrical pin being configured to come to rest to a bone surface surrounding said countersunk recess in said bone, and wherein said plate-shaped body having edges adapted for applying a turning tool thereon for turning said device the said tool;

and

a setting device comprising a distal setting tool by means of which setting tool a countersunk recess can be managed in said bone corresponding to said cylindrical pin projecting from said plate-shaped body.

5. The instrumentarium of claim 4, wherein said setting tool is provided with a projecting pin, a length of which pin corresponds substantially to a length of the cylindrical pin projecting from said plate-shaped body of said suture retention device.

6. The instrumentarium of claim 5, wherein said projecting pin comprises a limit stop on a proximal end thereof.

7. The instrumentarium of claim 6, wherein said stop is configured as an annular flange.

8. The instrumentarium of claim 7, wherein said projecting pin has an oval contour.

9. The instrumentarium of claim 4, wherein a lateral longitudinal slot is provided in said setting device into which slot fixation threads for fixing said tendon replacement can be placed.

10. The instrumentarium of claim 9, wherein hooks for mounting said fixation threads are provided in a position remote from said setting tool of said setting device.

11. The instrumentarium of claim 10, wherein said setting device comprising a cross-shaped handle.

12. Instrumentarium for implanting a tendon replacement in a channel in a bone comprising

a suture retention device,

said suture retention device having a plate-shaped body,

a cylindrical pin projecting from said plate-shaped body and

at least two openings extending through said plate-shaped body and said cylindrical pin for threading fixation threads of a tendon replacement therethrough wherein said cylindrical pin being configured to come to snugly fit within a countersunk recess in a channel within a bone, an area of said plate-shaped body surrounding said cylindrical pin being configured to come to rest to a bone surface surrounding said countersunk recess in said bone, and wherein said plate-shaped body having edges adapted for applying a turning tool thereon for turning said device with said tool;

and

a knot holder comprising a handle and a bar projecting distally there from, whose distal end is provided with a notch intended to hold fixation threads when they are being knotted on said suture retention device.

13. Instrumentarium for implanting a tendon replacement in a channel in a bone comprising

a suture retention device,

said suture retention device having a plate-shaped body,

a cylindrical pin projecting from said plate-shaped body and

at least two openings extending through said plate-shaped body and said cylindrical pin for threading fixation threads of a tendon replacement therethrough wherein said cylindrical pin being configured to come to snugly fit within a countersunk recess in a channel within a bone, an area of said plate-shaped body surrounding said cylindrical pin being configured to come to rest to a bone surface surrounding said countersunk recess in said bone, and wherein said plate-shaped body having edges adapted for applying a turning tool thereon for turning said device with said tool;

and

a tensiometer, whose distal end can be pulled out against an action of a spring, said distal end carrying a hook that can be engaged into a loop of fixation threads formed on said suture retention device.

14. Instrumentarium for implanting a tendon replacement in a channel in a bone comprising

a suture retention device,

said suture retention device having a plate-shaped body,

a cylindrical pin projecting from said plate-shaped body and

at least two openings extending through said plate-shaped body and said cylindrical pin for threading fixation threads of a tendon replacement therethrough wherein said cylindrical pin being configured to come to snugly fit within a countersunk recess in a channel within a bone, an area of said plate-shaped body surrounding said cylindrical pin being configured to come to rest to a bone surface surrounding said countersunk recess in said bone, and wherein said plate-shaped body having edges adapted for applying a turning tool thereon for turning said device with said tool;

and

a button turning tool that can be applied upon said edges on said device for rotating said suture retention device.
