Description

Medical steel plate list clamps multidirectional bending plastotype pincers

Technical field

The utility model relates to a kind of improvement of medical steel plate bending machine, and specifically a kind of medical steel plate list clamps multidirectional bending plastotype pincers.

Background technology

Along with the development of communication, the complicated fracture incidence is more and more, and betides person between twenty and fifty mostly, involves on distal part of femur, the condyle, between condyle and involve knee joint etc.At present, need carry out bone surgery mostly for this type of fracture, fixing with medical steel plate, steel nail etc.Used medical steel plate all will give curved by the physiology curvature requirement of different fracture sites, in operation, also will carry out bending with bending machine for nonconforming position.Employed bending machine comprises that handle and toothed spanner constitute in operation at present, need be with two bending machines during use, bending is carried out at two positions that are stuck in medical steel plate, the weak point of this bending machine is: 1, because firmly bigger, the easy landing of medical steel plate, so to medical steel plate bending the time, need control medical steel plate with finger, more bothersome so again; 2, to the crooked difficulty of the end bending of medical steel plate and shaped face, difficulty especially along the direction bending of medical steel plate rib time the especially; 3, when the medical steel plate of bending, pulling teeth easily causes damage to medical surface of steel plate, easily produces the rust feedback behind the high-temperature sterilization.

Summary of the invention

The purpose of this utility model is to provide a kind of can prevent medical steel plate landing, again can be to any bending of medical steel plate, can also singly clamp operation, can not produce damage, and easy to operate, time saving and energy saving medical steel plate list clamps multidirectional bending plastotype pincers medical surface of steel plate.

For reaching above purpose, the technical scheme that the utility model adopted is: this medical steel plate list clamps multidirectional bending plastotype pincers, by a left side, right pincers handle and the binding clip that connects as one thereof constitute, a left side, the front end of right pincers handle is fixed by bearing pin, it is characterized in that with a left side, the right clamp headend portion that clamps the handle connection establishes steel plate respectively presss from both sides mouth and the moving folder mouth of steel plate surely, the steel plate card entry slot that steel plate presss from both sides mouthful is surely established two, perpendicular to its fixing binding clip, its two steel plate card entry slots are in the both sides with its fixing binding clip symmetrically, the moving folder mouth of steel plate is fixed on the end of the binding clip of right pincers handle, leading portion inboard at left side pincers handle is provided with pin slide groove and slide bar guide pad, block on the rear inside of left side pincers handle is fixing, the slide opening that the front end of slide bar passes the slide bar guide pad is fixed on the middle part of bearing pin through the bearing pin sliding tray, the back segment of slide bar is a screw rod, pass the circular hole of block, at rear end rotation adjusted nut, rotation by adjusting nut, slide bar can spur or promote bearing pin, thereby the binding clip that makes right pincers handle and connect as one backward or move forward, the moving folder mouth of steel plate is pulled back or to protracting, thereby make the medical steel plate that clamps crooked backward or to front curve.The utility model is also implemented by following measure: described steel plate presss from both sides mouth surely and is made of horizontal support arm and two steel plate card entry slots, the transverse width of two steel plate card entry slots is 1cm, the degree of depth is consistent with the width of medical steel plate, the width that steel plate snaps in notch gets final product than the thickness of medical steel plate is slightly wide, bottom land exceeds 0.3-0.5cm than horizontal support arm inner surface, main effect is when firmly pressing the pincers handle, can realize the direction bending of medical steel plate along its rib; Also be provided with scale on slide bar, to observe medical steel plate crooked radian, the inner surface that moving folder mouth of steel plate and steel plate press from both sides mouth surely is smooth flat, in case biting to steel plate.When using the utility model, surely two steel plate card entry slots that press from both sides mouthful with steel plate snap in from one side of medical steel plate, snap in the steel plate card entry slot of the moving folder of steel plate mouthful another side from medical steel plate, press the pincers handle, clamp medical steel plate, turn adjusting nut, the moving folder mouth of steel plate spurs medical steel plate backward or forward, can make the surface curvature of medical steel plate along medical steel plate, and its crooked radian can be represented referring to the scale on the slide bar, if need of the direction bending of medical steel plate along its rib, can realize as long as firmly hold the pincers handle, in addition, by the medical steel integrated circuit board go into the moving folder of steel plate mouthful and steel plate press from both sides surely mouth how much, appropriate regulation and control can realize the bending of other shaped face.

The beneficial effects of the utility model are: compare with the steel plate bending machine of present use, single pincers can be realized the multiple bending of medical steel plate, and are convenient to operation, not only prevent landing, also do not damage medical steel plate, be beneficial to the carrying out of bone outer operation, can improve operation quality and speed.
