Description

A kind of screw driver for orthopaedics

Technical field

A kind of medicine equipment is the utility model is related to, particularly a kind of screw driver for orthopaedics.

Background technology

In the bone surgery of medical science, for case of fracturing, generally require and treated by way of fixation steel plate, steel Plate needs to be fixed together by screw and bone, and Medical screw is smaller, and handling are very inconvenient, and screw with screwdriver when being fixed It usually can from it drop, very big inconvenience is brought to bone surgery.And because screw is smaller, use current screwdriver When being fixed, it is necessary to by the position and direction for holding pincers adjustment screw, when operative site otch is smaller, it has not been convenient to make With pincers is held come the position of adjusting screw, inconvenience is brought to medical worker.In addition, the cutter head of existing screwdriver is consolidated with knife bar Surely connect as one, be not easy to change.

The content of the invention

The technical problems to be solved in the utility model is in view of the shortcomings of the prior art, to propose a kind of screw driver for orthopaedics, It is simple in construction, be conveniently adjusted with fixing screws position, avoid toner screw, reduce operation time, safe operation, be medical matters Personnel bring conveniently.

The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of screw driver for orthopaedics, Including cutter head, knife bar and handle of a knife, one end of the knife bar is threadedly coupled with cutter head, and the other end is fixedly connected with handle of a knife, the knife Sleeve pipe is provided with by screw thread on bar, described sleeve pipe bottom is concordant with head top surface, and the both sides of described sleeve pipe have been respectively fixedly connected with " L " shape support, the bottom of two " L " shape supports are connected to arc card, and one end of two arc cards is hinged, and the other end passes through Have contact with and connected with multiple snap rings；The handle of a knife surface is provided with multiple grooves for being used to fix draw point.

Screw driver for orthopaedics provided by the utility model, it is simple in construction, it is easy to operate, it can fix and adjust when in use spiral shell Adjusting screw, avoid screw from coming off, when draw point needs bending, groove only need to be placed in bending at exposed draw point afterbody, Operating time is shortened, is palliated the agonizing sufferings for patient.

Preferably, the handle of a knife is annular hand grip.Annular hand grip, the moment of torsion of screwdriver is added, operation is time saving and energy saving, just In quickly screw is back-outed.

Preferably, the handle of a knife is provided with anti-slip veins.Occur skidding now between hand and handle of a knife when avoiding operating screwdriver As.

Preferably, it is covered with absorbent cotton on the arc card.When screw is screwed onto correct position by screwdriver, on arc card Absorbent cotton is by trace of blood wiped clean.

Preferably, described sleeve pipe is provided with hinged seat, and " L " the shape support is articulated with hinged seat.

Preferably, the cutter head front end is coated with magnetosphere.Be advantageous to accurate setscrew, there is absorption to screw Effect, avoids screw from deviateing.

Compared with prior art, the beneficial effects of the utility model are：Screw driver for orthopaedics provided by the utility model, knot Structure is simple, easy to operate, is easy to fixed and adjusts screw, can avoid skidding occur when operating screwdriver, shorten Operating time, reduce patient's pain.
