Background technology
The human limb long diaphysis, after suffering the violence factor effect of various different sizes, different directions, can form various fracture, fracture is rear owing to muscle contraction around the limbs, muscle distributes also uneven around the limbs in addition, also has the limbs action of gravity, the different factors such as mode of transport, the displacement such as fracture site can overlap after the fracture, rotation, angulation even pulverize scattered.At present, the apparatus that resets for acropathy long bone fractures both at home and abroad is beak shape automatic center bone holding forceps, when resetting, the patient is with two beak shape bone holding forceps clamping two broken ends of fractured bone of fracturing respectively, and two handss firmly pull open, rotation, involutory fracture end, the displacements such as fracture end is overlapping to correct, rotation, angulation, because of patient's muscle sometimes strongr strong, or the reason such as the time is long after the fracture, it is overlapping more that muscle contracture causes fracture end, pulling open with manpower wastes time and energy, and difficulty resets.Existing fracture reposition instrument, the structure that has is single, can't take into account simultaneously displacements such as correcting fracture end is overlapping, rotation, angulation; The structure that has is complicated heavy again, and wound is larger, complex operation, and fracture end is fixing not firm, and steel plate is put inconvenience.
Summary of the invention
The purpose of this utility model is: design a kind of fracture reposition instrument, can correct overlapping, rotation, angulation comprehensively even pulverize the displacement such as scatter, structure is relatively simple, and is easy to operate, the fracture end fixation, save doctor's muscle power, shorten operating time, reduce the wound of operative site, it is painful to reduce patient, accelerating bone healing improves success rate of operation.
Technical solution of the present utility model is: this fracture reposition instrument comprises that two bone holders, two push plate and an adjusting screw(rod), installs on the bone holder and pushes plate, pushes to connect adjusting screw(rod) between the plate, wholely consists of positor; Wherein, described bone holder comprises caliper and adjusting rod, chela is socketed in through rotating shaft and forms the side pincers on the clamp handle, the both sides pincers connect and compose caliper through axis, two chelas of caliper are the formula of filling the span of a man's arms, one end of adjusting rod is flexibly connected on the side clamp handle through transverse axis, and the other end of adjusting rod passes the through hole of opposite side clamp handle and at its end adjusting nut is installed; Wherein, the described plate of pushing comprises plate body, connecting axle, contiguous block placed in the middle, screw rod and nut, the screw rod penetration type is installed on the contiguous block placed in the middle, the top mounting nuts of screw rod, the bottom of screw rod connects plate body, plate body is fixed on through connecting axle on the axis of side pincers of bone holder, and contiguous block placed in the middle is suspended between two clamp handles of bone holder; Wherein, described adjusting screw(rod) comprises the body of rod and setscrew nut, and bulb is established in a wherein end of the body of rod, establishes screw thread on the body of rod, and the bulb of the body of rod heads in the groove of pushing plate of a side bone holder, and the other end of the body of rod passes the circular hole of pushing plate of opposite side bone holder
Fixed by setscrew nut.
Wherein, establish square section pile at the body of rod of adjusting screw(rod), square section pile cooperates spanner.
Wherein, long handle is helped in socket on the clamp handle.
During use, two bone holders are used for securely clamping fracture two ends, rotate adjusting screw(rod) by spanner, adjust two and push the plate distance, two bone holders are by actions such as rotation, folding tops, correct fracture end rotation displacement, angulation displacement, the bone cips after angulation displacement and rotation displacement are corrected can be under direct-view smooth anatomical reduction; After resetting, insert steel plate and fix.
The utlity model has following advantage: 1, the rotating shaft socket is arranged between clamp handle and chela, chela can rotate at self longitudinal axis, therefore both sides clamp together when embracing, chela can adapt to the inconsistent conical in shape of up and down bore of clamping skeleton automatically, thereby control more docilely, tightr, control securely skeleton and fracture end; 2, push plate and adjusting screw(rod) cooperatively interacts, push effectively, can fully correct the fracture overlapping displacement, and by comprehensively correction rotation of the actions such as rotation, folding top, angulation even the pulverizing displacement such as scatter; 3, bone holder is inserted from the skeleton both sides, must not peel off too much soft tissue, and is simple to operate, inserts conveniently, saves doctor's muscle power, shortens operating time, reduces the wound of operative site, and it is painful to reduce patient, and accelerating bone healing improves success rate of operation.
