Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Example one

As shown in fig. 1-5, the hepatobiliary surgery calculus removing device provided in this embodiment includes two forceps handles 1 having a cavity therein, and the forceps handles 1 are hinged to each other to form a shearing structure; the inside of the top end of the forceps handle 1 is slidably connected with a telescopic forceps arm 2, and the top end of the telescopic forceps arm 2 is detachably connected with a forceps head 3 through a locking mechanism; an upper jack 21 communicated with the cavity of the telescopic clamp arm 2 is arranged on the telescopic clamp arm 2.

It should be noted that the shape of the binding clip 3 has two types, one is straight, the other is bent, and the two types of binding clips can be connected with the telescopic tong arm 2 through the locking mechanism.

Wherein, locking mechanism includes slide opening 31, and slide opening 31 is seted up on 3 outer walls of binding clip, is equipped with first spring 5 in the slide opening 31, and the one end of first spring 5 links to each other with slide opening 31 inner wall, and the other end of first spring 5 is connected with inserted bar 4, and inserted bar 4 sets up in slide opening 31 and can slide along slide opening 31, and inserted bar 4 and last jack 21 looks adaptation, when fixed, inserted bar 4 inserts and establishes the fixed of realizing flexible tong arm 2 and binding clip 3 in last jack 21.
