Embodiment Construction

[0130] figure 1 with figure 2 A surgical instrument 1.1 is disclosed. The surgical instrument 1.1 includes a handle part 2.1 and a joint part 3.1. The joining part 3.1 includes a first post 8 and a second post 9. The handle part 2.1 is connected to the joint part 3.1 through a first cracking point 4 and a second cracking point 5.

[0131] The first post 8 and the second post 9 of the joint part 3.1 are connected by a connecting piece (Steg) 10. The post 9 of the joint 3.1 and the connecting piece 10 form an angle α. in figure 1 with figure 2 In the embodiment, the angle α is 26°.

[0132] The free ends of the posts 8 and 9 each have a tip 11. The tip is preferably polished. In addition, each of the posts 8 and 9 includes a plurality of barbs 12.

[0133] The joint part 3.1 includes a joint part collision surface 13. The collision surface 13 of the joint part is located on the surface of the connecting piece 10 of the joint part 3.1.

[0134] The handle part 2.1 includes a han...

Abstract

The invention provides a surgical instrument (1.1, 1.2) with an implant, which comprises a handle part (2.1, 2.1) and a predetermined breaking point (4, 5, 6, 7).The predetermined breaking point (4, 5, 6, 7) connects the implant with the handle part (2.1, 2.2), wherein the implant is a joining profile (3.1, 3.2).

Description

Technical field [0001] The present invention relates to a surgical instrument according to the features of the general concept of claim 1, as well as an insertion instrument (Einbring instrument) for the surgical instrument and a drilling jig (Bohrschablone) for the surgical instrument. Background technique [0002] Nails or clips are used to connect bone parts, for example in hand and foot surgery according to Weil, Scarf, Austin, Chevron and Cheil and many other operations. Clips are used to fix and / or compress bone parts and in most cases stay in the body. Sometimes these nails and / or clips are very small implants and are difficult to grasp due to their shape. With the insertion device according to the prior art, only a very time-consuming insertion of clips and / or nails is possible. Another problem when inserting nails and / or clips is that it is usually pre-drilled before inserting the clips. Pre-drilled holes are difficult to find after removing the drill bit. The drilli...
