Abstract
The utility model discloses a smooth silk screw of orthopedics takes out instrument relates to orthopedic surgical instrument, mainly includes handle, connecting rod and work platform, and work platform is provided with the dead slot, and the dead slot can be for cross, in -line, triangle -shaped, square etc.. During the use, aim at the tail cap of sliding the silk screw with the dead slot on the work platform earlier, hole to the tail cap in the dead slot with the electric drill, drill out the recess of corresponding shape on the tail cap, then can take out the screw with supporting screwdriver. The utility model discloses the cooperation electric drill will be slided a screw very easily and take out to be applicable to all kinds of smooth silk screws, convenient to use shortens operation time greatly, reduces operation complication.
Description
Technical field
This utility model relates to a kind of bone surgery specific purpose tool, is specifically related to a kind of orthopedic slipped screws and takes out instrument.
Background technology
Steel plate screw internal fixation is one of chief surgical method for the treatment of fracture, and after union of fracture, most inside-fixtures need to be performed the operation taking-up again.But overlong time, screw bear the reasons such as bigger stress in vivo in patient operates lack of standardization, the problem of screw own, screw indwelling body, when screw all can be caused to take out, there is stripped thread.When occurring that this when problem doctor would generally use destruction screw tail cap separation screw or cut off the methods such as steel plate, its shortcoming is that complex operation, operating time are obviously prolonged, infect probability and increase, in some instances it may even be possible to cause the extra wound of bone and surrounding soft tissue.
Summary of the invention
The purpose of this utility model is the defect for prior art or deficiency, it is provided that a kind of orthopedic slipped screws takes out instrument.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of orthopaedics slipped screws takes out instrument, and it includes handle, connecting rod and work platforms, and work platforms is provided with dead slot.
Specifically, described connecting rod end is provided with external screw thread, and work platforms side inner face is provided with female thread, and connecting rod carries out coupling with work platforms by screw thread and is connected.
Specifically, the dead slot of described work platforms can be provided with different models according to screw tail cap diameter.
Specifically, dead slot can be cross, in-line, triangle, square etc..
During use, first the tail cap according to slipped screws selects the work platforms of respective model, the dead slot of work platforms is directed at the tail cap of slipped screws, tail cap is holed in being drilled in dead slot by electricity consumption, tail cap gets out the groove of respective shapes, then with the groove in screwdriver kit alignment tail cap, screw can be taken out.
The beneficial effects of the utility model are: this instrument can be according to different screw tail cap diameter unrestricted choice work platformses, it is adaptable to all kinds of slipped screws of orthopaedics, coordinate electric drill, it is easy to taken out by slipped screws, easy to use, reduce postoperative complication.
