Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of multiplex orthopaedics screwdriver.
Background technology
The screwdriver that uses of orthopaedics mostly is integrative-structure clinically, if be screwed into or the screw of the different model of back-outing needs frequently to change the screwdriver of different model, extends operating time, also causes the wasting of resources.In addition, because screw and screwdriver are not relatively fixed, often occur the phenomenon of screwdriver slippage in operation process, bring operating difficulties to the doctor, directly affect the operation process.
Summary of the invention
The purpose of this utility model is to provide a kind of multiplex orthopaedics screwdriver that is convenient for changing cone, effectively avoids slide fastener.
This utility model is that the technical scheme that adopts of its technical problem of solution is as follows: multiplex orthopaedics screwdriver, comprise cone, cone bar, cone handle, described cone is one-shot forming, described cone front end has conehead, sleeve, hollow-core construction between described conehead and sleeve, described conehead cross section is regular polygon, described sleeve inner cross section is regular polygon concentric with the conehead cross section and that the limit number equates, described cone bar front end has the endoporus that matches with cone, and described cone bar has the screw that matches with nut at the side correspondence position with cone.
Described regular polygon is equilateral triangle, square or regular hexagon.
Described cone is being provided with anti-skidding projection.
The utlity model has following beneficial effect: outside cone of the present utility model, sleeve is arranged, during use, energy and the corresponding dual interlock of screw, effectively avoid slide fastener; This utility model cone is demountable structure with the cone bar, can be convenient for changing as required cone; Frictional force when cone can effectively increase gripping to upper anti-skidding projection, easy to operate, laborsaving.
