Abstract

A surgical device for tissue perforation (1) includes a perforation member (2), characterized in that it includes a stop (4) that presses on the outer surface of tissue (1) and is mobile relative to the perforation member, and reaction elements (3) configured to resist the movement of the stop (4) relative to the perforation member (2). The device will be used for the perforation of all types of tissue and especially bone tissues during which the withdrawal of the perforation member from the tissue is difficult.

Claims

1. Surgical device for a tissue (1) perforation comprising perforation means (2) characterized in that it comprises a stop (4) that presses on the outer surface of tissue (1) and is mobile relative to perforation means (2), and reaction means (3) configured to resist the movement of the stop (4) relative to the perforation means.

2. Device according to claim 1 wherein the stop (4) cooperates with the perforation means (2) to form a seal that limits undesirable material entering between the perforation means (2) and the stop (4).

3. Device according to claim 1 wherein the stop (4) surrounds the perforation means (2).

4. Device according to claim 1 wherein the stop (4) comprises an application surface peripheral to the perforation means (2).

5. Device according to claim 1 wherein the stop (4) comprises an end-of-travel stop (8) that limits the displacement of the perforation means (2) relative to the stop (4).

6. Device according to claim 5 wherein the end-of-travel stop (8) is located in the proximal part of the stop (4) pressing on the outer surface of a tissue (1).

7. Device according to claim 1 wherein the reaction means (3) are elastically deformable.

8. Device according to claim 1 wherein the reaction means (3) are compressible.

9. Device according to claim 1 wherein the reaction means (3) comprise a spring.

10. Device according to claim 1 wherein the reaction means (3) are made of an elastically deformable material.

11. Device according to claim 1 wherein the stop (4) is formed by the distal end of the reaction means (3).

12. Impulse impactor for surgical perforation of a tissue comprising the surgical device according to claim 1 and impulse generating means.
