Technical field
The present invention relates to medical orthopaedic technique field more particularly to a kind of dedicated episome withdrawing devices of Orthopedic Clinical.
Background technique
The episome being frequently necessary in Orthopedic Clinical in cleaning glenoid, it is common practice to use surgical clamp under arthroscope
Episome is clamped into taking-up.And the advantage that arthrocsopic surgery is small with its wound, recovery is fast, curative for effect has pushed rapidly joint micro-
Create the development of surgery.Spur episome cleaning art becomes preferred operation plan under arthroscope.Most of joint bodies is in flat ellipse
Circle, it is smooth, free, it takes out difficult.
Currently used episome withdrawing device is usually surgical clamp, due to being used exclusively for taking episome to design
There is limitation in the process.And it is difficult to enter rear clamp from mini-incision due to not being arthroscope special equipment for traditional surgical clamp
With open, operate it is more troublesome, and even if clamping after and also built on the sand, clamp after easily slip, bring inconvenience to operation, because
This, a kind of new scheme of urgent need solves the technical problem, for this purpose, that the present invention provides a kind of Orthopedic Clinicals is dedicated free
Body withdrawing device.
