Abstract
The invention relates to a facet joint retractor, which is formed by hinging two tong arms a hinge pin. The facet joint retractor is characterized in that one sides of front ends of the two tong arms are respectively provided with a cantilever; each cantilever is provided with a kirschner wire hole; inner sides of rear parts of the two tong arms are respectively provided with a spring piece; free ends of the two spring pieces are mutually engaged; the tail end of one of two tong arms is connected with a trapezoidal lock by a lock pin. When the facet joint retractor provided by the invention is used, firstly, two kirschner wires respectively penetrate skeletons which correspond to a facet joint, so that the two kirschner wires are parallel. Then, the two kirschner wires are respectively led into the kirschner wire holes arranged in the cantilevers to oppositely squeeze the rear parts of the two tong arms, so that the two cantilevers are mutually separated, and therefore, the facet joint is retracted to form a joint space, and the joint retracted state is locked and kept by the trapezoidal lock. The facet joint retractor provided by the invention has the advantages that the structure is simple, manufacturing is convenient, the use is convenient, a retracting effect is stable, an operating field is clear, operation techniques are convenient, and the operation time is reduced.
Description
Technical field
The present invention relates to technical field of medical instruments, is a kind of little joint retractor specifically.
Background technology
Clinically, the little joint of ankle and foot or hand is merged or is carried out resetting and fixedly the time, usually needing the joint is retracted of intra-articular fracture, appears the joint space, so that the direct-view articular surface is operated.At present, the common method that retracts of little joint is divided into two classes.One class is the free-hand method that retracts of assistant, needs 1-2 name assistant to carry out countertraction, and this class methods joint space retracts poor effect, and assistant's fatigue easily occurs, and affects the operator operation; Another kind of the cone-plate retractor need to insert and retract in the joint space in order to adopt the cone-plate retractor to retract, and clinical practice is found, retracts the rear patient of impact to observation and the operation of articular surface, and can take operating field, affects operation technique.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of little joint retractor simple in structure, easy to use, little on operating field impact is provided.
The present invention solves the technical scheme that its technical problem takes: a kind of little joint retractor, formed through bearing pin is hinged by two clamp handles, it is characterized in that two clamp handle front end one sides are respectively equipped with cantilever, cantilever is provided with the Kirschner wire hole, two tong arm posterior medials are respectively equipped with spring leaf, two mutual interlocks of spring leaf free-end, one of them clamp handle tail end is by lock pin and trapezoidal phase-locked a connection.
The invention has the beneficial effects as follows: compare with the method for present application, simple in structure, be convenient to make, easy to use, retract effect stability, operating field is clear, is convenient to operation technique, reduces operating time.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing is structural representation of the present invention.
1. cantilevers among the figure, 2. Kirschner wire hole, 3. clamp handle, 4 bearing pins, 5 spring leafs, 6. trapezoidal lock, 7. lock pin.
The specific embodiment:
As shown in drawings, a kind of little joint retractor through bearing pin 4 hinged forming, is characterized in that two clamp handles by two clamp handles 3
Front end one side is respectively equipped with cantilever 1, and cantilever 1 is provided with 2, two tong arm 3 posterior medials in Kirschner wire hole and is respectively equipped with spring leaf
, the mutual interlock of two spring leaf 5 free-ends, one of them clamp handle 3 tail end is connected with a trapezoidal lock 6 by lock pin 7.
When the present invention uses, prior to respectively penetrating one piece of Kirschner wire on skeleton corresponding to little joint, make two Kirschner wires parallel.Then two Kirschner wires are introduced respectively in the Kirschner wire hole 2 that cantilever 2 is provided with, to squeezing the rear portion of two clamp handles 3, two cantilevers 2 are separated from each other, thereby retract the joint space, and pin with trapezoidal lock 6 and to keep the joint and retract state.
