Abstract

A surgical device for arthroscopy includes an insertion arm having a folded contact end, a handle connected to a connection end of the insertion arm, opposite to the folded contact end, and extending transversely to the insertion arm, and a retrieval element connected to the insertion arm and mobile along the insertion arm between a retracted position and an extracted position in which it intercepts a leading end of a suture thread at the folded contact end, and mobile between the extracted position and the retracted position in which it holds the leading end. The retrieval element is a basket made of flexible material defining a containment volume for receiving said leading end of the suture thread. The containment volume is configured to expand in the transition between the retracted position and the extracted position and to shrink in the transition between the extracted position and the retracted position.

First claim

1 .- 15 . (canceled)

16 . A retrieval group for a surgical device comprising:
a retrieval element configured to receive one leading end of a suture thread, a switch configured to switch the retrieval element between a non-operational configuration, wherein the retrieval element is in a retracted position and does not intercept the leading end of the suture thread, and a semi-operational configuration, wherein the retrieval element is in an extracted position to intercept said leading end, and between the semi-operational configuration and an operational configuration, wherein the retrieval element is in the retracted position and holds said leading end, and at least one attachment element configured to reversibly connect the retrieval group to an insertion arm of a pointer, said pointer comprising an insertion arm that has a folded contact end configured to abut the surgical device against a patient's bone, and a handle connected to a connection end of the insertion arm, opposite to said folded contact end, and extending transversely to said insertion arm.

17 . The retrieval group according to claim 16 , comprising a containment channel of the retrieval element, wherein said retrieval element is located completely inside of said containment channel in the retracted position and emerges at least partially beyond an outlet section of said containment channel in the extracted position.

18 . The retrieval group according to claim 16 , wherein said retrieval element is a basket made of flexible material, wherein the basket defines a containment volume suitable for receiving said leading end of the suture thread.

19 . The retrieval group according to claim 18 , wherein said containment volume is configured to expand in transition from the retracted position to the extracted position and to shrink in transition from the extracted position to the retracted position.

20 . The retrieval group according to claim 18 , wherein the basket is a cage defined by a plurality of threads spaced apart by interstices, said interstices configured to enable passage of the suture thread.

21 . The retrieval group according to claim 18 , wherein said basket is made of a shape memory material.

22 . The retrieval group according to claim 18 , wherein said basket is made of Nitinol.

23 . The retrieval group according to claim 16 , wherein the switch comprises a slider configured to move the retrieval element.

24 . The retrieval group according to claim 23 , wherein the slider is a sliding block.

25 . The retrieval group according to claim 23 , wherein the slider is a castor.

26 . The retrieval group according to claim 16 , comprising a spring connected to the switch and configured to keep the retrieval element in the retracted position.
