Description
Technical field
The utility model relates to medical instruments field more particularly to a kind of detachable Intertrochanter fracture of femur debriders.
Background technique
Reduction, fixation and the functional training of fracture are three big principles of fractures and the basic principle of rehabilitation,
The reduction of fracture is clinically divided into anatomical reduction and functional reduction, and repositioning method is divided into manipulative reduction and open reduction two
Kind, functional training is the main means of rehabilitation after fracture, patient should be encouraged early stage to carry out functional training, to promote fracture to be cured
It closes, prevents or reduces the generation of sequelae, complication.In recent years, with the rapid development of medical instrument, the reduction of fracture is usual
Using functional reduction.And when femur and fracture of tibia reduction, since bone is long, only by manually carry out reduction need medical staff compared with
Big strength and only by naked eyes it cannot be guaranteed that bone by reduction in place.
For example, a kind of detachable fracture of neck of femur debrider is disclosed in Publication No. CN2085655U patent document, by
Interior mandril and hollow rotating lever composition, it is characterized in that the front end of hollow rotating lever has tapered thread to revolve head, there is spanner in rear end
Plane, there is in a cross crotch that mandril is in hollow rotating lever on the body of rod of front, when the front end precession internal taper hole of interior mandril, cone
Shape screw thread revolves head and is divided into pintongs outward by cross crotch.This patent, which overcomes, is easy to damage sclerotin with several bone nails, is easy dislocation,
The low disadvantage of success rate of operation, thus keep operation simple, patient's pain is reduced, and patients ' recovery is fast.However, this patent needs doctor
