Abstract

A tissue protection sleeve for use in suprapatellar surgery is provided. The sleeve has a first end, a second end, an inner surface and an outer surface. The sleeve further comprises at least two open grooves that extend along the inner surface from the first end to the second end. The grooves are adapted to accommodate elongated fixation elements inserted into a tibia. A drill guide sleeve and a trocar for inserting a guide wire are also provided and can be accommodated by the tissue protection sleeve.

First claim

The invention claimed is:

1. A system comprising:
a tissue protection sleeve adapted for use in surgical procedures, the tissue protection sleeve having a longitudinal axis and comprising a first end, a second end, an inner surface, and an outer surface;
wherein the tissue protection sleeve further comprises at least two grooves extending along the inner surface from the first end to the second end, wherein the grooves are adapted to accommodate elongated fixation elements, the grooves open to the sleeve inner surface;
a drill sleeve adapted to be inserted into the tissue protection sleeve;
wherein an outer surface of the drill sleeve closes the grooves of the tissue protection sleeve to define at least two closed canals adapted to receive and guide the elongated fixation elements;
wherein the drill sleeve comprises a portion with an enlarged diameter at a first end of the drill sleeve;
wherein the portion of the drill sleeve with an enlarged diameter comprises at least two openings at an end facing the second end of the drill sleeve, and wherein the at least two openings are axially aligned with the at least two closed canals of the sleeve when the drill sleeve is inserted into the tissue protection sleeve;
whereby an elongated fixation element can be inserted into each of the closed canals through the respective opening; and
wherein the tissue protection sleeve comprises an elastic material which permits bending of the tissue protection sleeve along the longitudinal axis.

2. The system according to claim 1 , wherein the tissue protection sleeve has a portion along the longitudinal axis where the outer surface adjacent to the at least two grooves projects radially outwardly of the adjacent outer surface.

3. The system according to claim 1 , wherein the grooves are substantially parallel with the longitudinal axis of the sleeve.

4. The system according to claim 1 , wherein the two grooves are located substantially at opposite sides along a circumference of the inner surface.

5. The system according to claim 1 , wherein the angular distance between the two grooves along a circumference of the inner surface is less than 180°.

6. The system according to claim 1 , wherein the tissue protection sleeve further comprises a gripping flange portion radially and outwardly from the first end of the sleeve.

7. The system according to claim 1 , wherein the at least two openings in the drill sleeve are inclined relative to the longitudinal axis of the drill sleeve.

8. The system according to claim 7 , wherein the tissue protection sleeve and the drill sleeve are rotationally locked relative to each other.

9. The system according to claim 8 , wherein the drill sleeve comprises a recess at the circumference of the portion with an enlarged diameter.

10. The system according to claim 9 , wherein the system further comprises at least two fixation elements adapted to be inserted in the grooves.

11. The system according to claim 10 , wherein the system further comprises a device adapted to engage and to position at least one of the sleeve and the drill sleeve with respect to the tibia.

12. The system according to claim 1 , wherein the system further comprises a trocar adapted to be inserted into the drill sleeve.

13. A method for suprapatellar surgery, comprising: providing a system comprising;
a tissue protection sleeve adapted for use in surgical procedures, the tissue protection sleeve having a longitudinal axis and comprising a first end, a second end, an inner surface, and an outer surface;
wherein the tissue protection sleeve further comprises at least two grooves extending along the inner surface from the first end to the second end, wherein the grooves are adapted to accommodate elongated fixation elements, the grooves open to the sleeve inner surface;
a drill sleeve adapted to be inserted into the tissue protection sleeve;
a trocar adapted to be inserted into the drill sleeve;
wherein an outer surface of the drill sleeve closes the grooves of the tissue protection sleeve to define at least two closed canals adapted to receive and guide the elongated fixation elements;
wherein the drill sleeve comprises a portion with an enlarged diameter at a first end of the drill sleeve;
wherein the portion of the drill sleeve with an enlarged diameter comprises at least two openings at an end facing the second end of the drill sleeve, and wherein the at least two openings are axially aligned with the at least two closed canals of the sleeve when the drill sleeve is inserted into the tissue protection sleeve;
whereby an elongated fixation element can be inserted into each of the closed canals through the respective opening;
inserting at least two fixation elements into the tibia through a respective one of the at least two openings of the drill sleeve enlarged portion and the respective grooves of the tissue protection sleeve;
inserting a drill guide sleeve into the tissue protection sleeve;
inserting a trocar into the tissue protection sleeve;
inserting a guide wire into a tibia through the trocar;
thereafter removing the trocar;
drilling a bore in the tibia using the drill sleeve as a guide; and
thereafter inserting a bone nail in the drilled tibia.

14. The method as set forth in claim 13 wherein the trocar is inserted into the drill sleeve.

15. A system comprising:
a tissue protection sleeve adapted for use in surgical procedures, the tissue protection sleeve having a central longitudinal axis and comprising a first end, a second end, an inner surface, and an outer surface;
wherein the tissue protective sleeve further comprises at least two grooves extending along the inner surface from the first end to the second end, wherein the grooves are adapted to accommodate elongated fixation elements, the grooves open to the sleeve inner surface;
a drill sleeve having a central longitudinal axis adapted to be inserted into the tissue protection sleeve;
wherein an outer surface of the drill sleeve closes the grooves of the tissue protection sleeve to define at least two closed canals adapted to receive and guide the elongated fixation elements;
wherein the drill sleeve comprises a portion with an enlarged diameter at a first end of the drill sleeve;
wherein the portion of the drill sleeve with an enlarged diameter comprises at least two openings at an end facing the second end of the drill sleeve, and wherein the at least two openings are axially aligned with the at least two closed canals of the sleeve when the drill sleeve is inserted into the tissue protection sleeve, wherein the at least two openings of the drill sleeve and the two grooves of the tissue protection sleeve are angled towards their respective central longitudinal axis; and
whereby an elongated fixation element can be inserted into each of the closed canals through the respective opening.

16. A system comprising:
a flexible tissue protection sleeve adapted for use in surgical procedures, the flexible tissue protection sleeve having a central longitudinal axis and comprising a first end, a second end, an inner surface, and an outer surface, the flexible sleeve second end capable of flexing from a first configuration with a first orientation of the central longitudinal axis to a second configuration with a second orientation of the central longitudinal axis different than the first orientation;
wherein the flexible tissue protective sleeve further comprises at least two grooves extending along the inner surface from the first end to the second end, wherein the grooves are adapted to accommodate elongated fixation elements, the gro
