Abstract
The invention discloses a pair of reduction forceps. The pair of the reduction forceps comprises at least two bone clamping forceps bodies and a connection rod connecting the two bone clamping forceps. The connection rod comprises a connection rod body, an adjusting rod and a longitudinal adjusting mechanism enabling the connection rod body to move relative to the adjusting rod in the longitudinal direction. According to the reduction forceps, people only need to adjust rotation of a gear so that broken bones can move relatively along the connection rod in the longitudinal direction, and accordingly reduction of the broken bones is achieved. Manual adjustment is not needed, the positions of the broken bones do not need to be fixed, after broken bone reduction is finished, the relative position of the two bone clamping forceps bodies can be locked through the connection rod body, and accordingly the relative position of the broken bones is locked. The situation that the broken bones are dislocated after subsequent operation of an operation is avoided, so that labor intensity of medical staff is lightened, and pains of patients are relieved.
Description
Technical field
The present invention relates to medical instruments field, particularly a kind of reduction forceps.
Background technology
After fracture, generally need to adopt bone holding forceps that knochenbruch is resetted, and be fixed by steel plate, screw etc.Conventional reduction forceps, main two hinged forming of tong arm by X-type, front end is as clamp, rear end is as handle, after fracture, two sections of knochenbruch that disconnect, due to pullling under traction at muscle, there will be and be overlapping, in the time that knochenbruch is resetted, need to use at least two reduction forceps to clamp respectively two sections of knochenbruch, and by medical worker, two sections of end bones are pulled open to reset position and with steel plate and fixed, the shift position size of two sections of knochenbruch need to be leaned on manual adjustment, knochenbruch is difficult to justify align, even sometimes, after knochenbruch resets, take away bone holding forceps and carry out steel plate when fixing, knochenbruch recovers original dislocation state, brought the inconvenience of work to doctor, also increased patient's misery simultaneously.
Therefore,, for overcoming the above problems, need one can clamp respectively two sections of knochenbruch and knochenbruch is drawn to reset position knochenbruch position is effectively locked, the reduction forceps of avoiding knochenbruch again to misplace.
Summary of the invention
In view of this, the object of the invention is to overcome defect of the prior art, provide a kind of knochenbruch can traction to reset position and to knochenbruch position to carry out the effectively reduction forceps of locking.Reduction forceps of the present invention, comprise at least two splenial bone pincers and the connecting rod that is connected adjacent two splenial bones pincers, longitudinal guiding mechanism that connecting rod comprises gonnecting rod body, adjusting lever and gonnecting rod body is longitudinally moved with respect to adjusting lever along it, longitudinally guiding mechanism comprises along gonnecting rod body and is longitudinally fixedly arranged on the tooth bar on gonnecting rod body, the lock-nut that is rotationally connected with adjusting lever and coordinates the gear of transmission and longitudinally move with respect to adjusting lever along it for locking gonnecting rod body with described tooth bar;
Further, described connecting rod also comprises makes the transverse adjusting mechanism of adjusting lever along gonnecting rod body transverse shifting, transverse adjusting mechanism comprises the screw that is connected with the rotatable single-degree-of-freedom of gear and the screwed hole along adjusting lever horizontally set, and screw and screwed hole are in mating connection and can carry out worm drive;
Further, described gear face is provided with interior hexagonal boss, and described screw is socket head screw;
Further, described splenial bone pincers comprise the caliper I and the caliper II that are hinged, caliper I and caliper II include the tong arm and the clamping part that are mutually permanently connected, clamping part is provided with the through hole that is communicated with its inner side and outside, in through hole, being provided with grip block and grip block governor motion and grip block can slide axially along through hole, grip block governor motion comprises screw rod, fixing head, Compress Spring and screws nut, and fixing head is fixed on and on clamping part and by through hole, covers and fixing head is provided with via hole; Screw rod one end is fixedly connected with grip block along grip block glide direction, the screw rod other end through the via hole on fixing head with screw nut and be connected by threaded engagement, Compress Spring is located in through hole also bullet and is peaked between fixing head and grip block;
