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 in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 4, the utility model provides an aspirator for arthroscopic surgery, including lag 1, the one end fixedly connected with clamping ring 2 of lag 1, the internal fixation cover of lag 1 is equipped with water conservancy diversion piece 3, the through-hole has been seted up along the axial to water conservancy diversion piece 3, and one end extends to the outside of lag 1, the external fixed surface of water conservancy diversion piece 3 has cup jointed the viscidity film 4 that is located lag 1 outside, outlet 5 has been seted up to the outer wall of lag 1, outlet 5 is connected with drain pipe 6, the bottom cover of drain pipe 6 is equipped with fixed mounting's fixed block 7, the thread bush 8 that is located the fixed block 7 outside is cup jointed in the activity of drain pipe 6 surface.

Wherein, lag 1 is the toper form, and lag 1's internal surface is smooth, and medical personnel are operating the in-process, can prevent the rivers of water and fall, have played good collection effect to lag 1's material is whole transparent, thereby is convenient for medical personnel to observe this aspirator is inside.
