Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: exchange stick that arthroscopic surgery used, including intervalve 1, intervalve 1's both ends are equipped with a plurality of flexible pipes 2, a plurality of annular recesses 3 have all been seted up to intervalve 1 and flexible pipe 2's interior table wall, and intervalve 1 and flexible pipe 2 lead to the axle center setting, flexible pipe 2 is close to intervalve 1's one end and has been seted up annular recess 3, the inside fixedly connected with snap ring 4 of recess 3, snap

ring

4 and 5 joints of draw-in groove, adjust the length of exchanging the stick through the flexible pipe 2 of pulling, and then make things convenient for the use and the accomodation of exchanging the stick.

Specifically, as shown in fig. 1, at least two telescopic pipes 2 are arranged at one end of the middle pipe 1, and the middle pipe 1 and the telescopic pipes 2 are made of metal materials harmless to human bodies, so that the use safety is improved.
