Description

A kind of wedge angle reduction forceps

Technical field

The utility model relates to the wedge angle reduction forceps of a kind of reduction forceps, especially bone surgery, belong to medical instrument skill Art field.

Background technique

On Orthopedic Clinical, the operation for needing to reset knochenbruch after fracture is frequently encountered, generally requires and adopts in such operation Knochenbruch is resetted with reduction forceps, and is fixed by steel plate, screw etc..Currently used reduction forceps, mainly by X type Two calipers hingedly form, surgery location is fixed in using knochenbruch to be resetted is clamped at the top of caliper, in operation Pullling traction and knochenbruch can be made to misplace due to muscle, to guarantee firm clamping knochenbruch, the front end of reduction forceps caliper generally in Tip-angled shape clamps knochenbruch by the wedge angle of caliper end, it is ensured that do not slip from reduction forceps in surgical procedure knochenbruch, but such The drawbacks of structure reduction forceps is: for the patient of old man or osteoporosis, since bone matrix is reduced, the intensity of bone ontology is low, The wedge angle insertion bone ontology of caliper end is too deep during surgery, unnecessary damage can be caused to diaphysis, or even bone split occurs etc. Contingency etc. occurs, while in order to guarantee clamping force, there are also the manual methods such as cooperate with screw rod and nut to adjust at present And keep the openings of sizes of caliper, the disadvantage is that, using the tools such as screw rod carry out manual setting method its fasten dynamics to behaviour Make personnel without any feedback, so that the tightness of knochenbruch is difficult to control, is also easy that not tight, cause is caused to damage or clamped to diaphysis Make fracture two broken ends of fractured bone closed reductions after again Yi Yiwei, it has to again clamping reset, delay treatment time, increase medical matters people The workload of member, while also increasing the pain of patient.

Summary of the invention

To solve the above-mentioned problems in the prior art, the purpose of this utility model is that: a kind of wedge angle reset is provided Pincers, can to avoid the insertion of pincers point, sclerotin is too deep damages to patient, while medical worker's holding when clamping knochenbruch can be made Suitable dynamics, the slip phenomenon for preventing clamping tension or occurring when clamping pine.

In order to achieve the above object, the technical solution adopted in the utility model are as follows: a kind of wedge angle reduction forceps, including two pass through The hinged caliper of pin shaft, two caliper front ends are respectively arranged with clamping binding clip, and fixation is set respectively for the bottom of two calipers It is equipped with finger ring, gripper clamp crown end is provided with wedge angle clamping part, the connecting portion setting of wedge angle clamping part and clamping binding clip There is the top expanded outward to hold body, the clamping binding clip ontology that the connection of body lower end is held on top is hollow arc ontology, hollow arc sheet Internal portion is radially fixed to be provided with binding clip block machine, and binding clip block machine center is provided with through-hole, and caliper upper end is the interconnecting piece of arc, arc The interconnecting piece of shape is threaded through in the hollow arc ontology of clamping binding clip, and the interconnecting piece top of arc is fed through in binding clip block machine Through-hole is provided with caliper block machine on caliper, is provided with compression spring between caliper block machine and binding clip block machine；Further, two It is respectively left caliper and right caliper body by the hinged caliper of pin shaft, locking dress is provided between left caliper and right caliper body Set, the locking device include the fixed sleeving being arranged on left caliper, the fixing axle being arranged on right caliper body and with fixation The fixed pin of casing connection, the fixed sleeving are arc hollow casing, and fixing axle is arc shaft, and fixing axle is threaded through fixing sleeve Guan Zhong offers the screw hole of perforation fixed sleeving side wall on the fixed sleeving side wall, and fixed pin is arranged on screw hole, fixed pin It is connect between screw hole by being threadedly engaged；Further, it is that body is held on hemispherical top that body is held on the top, and the wedge angle clamping part is solid Surely it is connected to the hemispherical sphere end pushed up and hold body；Further, the clamping binding clip lower end is fixedly installed sliding block, the sliding block It is slidably arranged on caliper；Further, the linear bearing with caliper cooperation is provided on the sliding block.

The positive advantageous effects of the utility model are: by being arranged between the wedge angle clamping part and caliper of caliper Body is held on the top expanded outward, wedge angle clamping part insertion bone can be prevented too deep, moreover it is possible to increase the friction between caliper and bone Power can make more stable fixation diaphysis；It, can be by chucking power by the way that compression spring is arranged between caliper and clamping binding clip Effective Feedback is buffered by compression spring to operator, can be prevented from clamping too tight or too loose situation and is occurred, The locking device of bushing type is set between two calipers, chucking power can not be interfered to feed back to operator when clamping, Caliper state can be fixed by tightening fixed pin after being clamped to suitable dynamics, conducive to the subsequent operation of operation；In gripper clamp The lower setting sliding block of head and linear bearing, can be such that gripper clamp head slides on caliper more smooth, reduce operation difficulty.
