Description

A kind of Kirschner wire folding forceps

Technical field

This utility model belongs to medical apparatus, especially a kind of Kirschner wire folding forceps.

Background technology

At present Kirschner wire is widely used in surgical operation, in bone surgery, is mainly used in the positions such as foot, hands, knee joint, ankle, and elbow, the tension band of knee and the auxiliary reset of various articular surface fracture pieces are fixing etc.Although for the reduction of the fracture fixedly provides a lot of convenience, also there are many complication in Kirschner wire.Mainly comprise two aspects: the tail end projection excitation that 1, Kirschner wire is sharp-pointed soft tissue around.2, Kirschner wire displacement.Therefore, must Kirschner wire bending cut short be embedded in subcutaneous.

Summary of the invention

The purpose of this utility model is to provide a kind of and overcomes Kirschner wire folding forceps in existing surgery, bone surgery and in use have the sharp tail end projection of needle point excitation soft tissue around, the defect of Kirschner wire displacement, bent external diameter is less than the Kirschner wire of 3mm, effective, accurately, can be like a cork Kirschner wire bending at an angle of 90, Kirschner wire direction along bending exits folding forceps, a kind of Kirschner wire folding forceps that labor-saving effect is definite.

Technical solution of the present utility model is such, a kind of Kirschner wire folding forceps, comprise the first clamp handle, the second clamp handle, the first binding clip, the second binding clip, boss, groove, hinged, with one voice, the first inner arc, the second inner arc, caliper, it is characterized in that caliper (11) has the first clamp handle (1), the second clamp handle (2), the first clamp handle (1), the second clamp handle (2) is overlapping hinged by hinged (7), the first clamp handle (1) front end has the second binding clip (4), the second clamp handle (2) front end has the first binding clip (3), the inner face of the second binding clip (4) has boss (5), the first binding clip (3) fluted (6), boss (5) snaps in groove (6) and coordinates, the first binding clip (3), the second binding clip (4) termination inner face interface has with one voice (8), the first inner arc (9), the second inner arc joins into one voice (8) between (10).

Penetrating one-tenth aperture, (8) top and bottom with one voice.

First inner arc (9) of (8), the second inner arc (10) have teeth with one voice.

The utility model has the advantages that Kirschner wire like a cork bending at an angle of 90, exit folding forceps along the Kirschner wire direction of bending, cut short Kirschner wire with scissor forceps and be embedded in subcutaneous.Laborsaving, accurate, effective.

Reference numeral: the first clamp handle (1), the second clamp handle (2), the first binding clip (3), the second binding clip (4), boss (5), groove (6), hinged (7), (8), the first inner arc (9), the second inner arc (10), caliper (11) with one voice.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is further described.

Embodiment 1, in the Kirschner wire internal fixation operation for the treatment of fracture, often uses the free-hand bending draw point of cutting pliers or other pliers.For the draw point bending of the fixing ossiculum piece in the abundant place of soft tissue or little tubular bone and all more difficult to the bending of about 1cm minute hand tail.Sometimes need to employ two pairs of pliers, require great effort time-consuming, movement range is large, also easily produces secondary damage, or makes the fracture end displacement that resets fixing.For this reason, we manufacture experimently into a kind of Kirschner wire folding forceps on the basis of cutting pliers, through clinical use, and the Kirschner wire of bent φ≤3mm, effect is fine, has feature laborsaving, accurate, definite effect.Using method: jaw open (jaw concave surface arm under, jaw convex surface arm is upper), push down surface of bone and bite gently the Kirschner wire of wanting bending on surface of bone, firmly close up jaw, just can be like a cork Kirschner wire bending at an angle of 90, Kirschner wire direction along bending exits folding forceps, cuts short Kirschner wire be embedded in and subcutaneously can complete operation with cutting nipper.

Embodiment 2, with reference to accompanying drawing, caliper (11) is made up of the first clamp handle (1), the second clamp handle (2), the first binding clip (3), the second binding clip (4), hinged (7), the structure of caliper (11) is with reference to the composition structure of commercially available electricians' plier, it opens the also using method of the existing electricians' plier of reference of using method of binding clip and grip objects, pull the first clamp handle (1), the second clamp handle (2), its first binding clip (3), the second binding clip (4) are opened work around point articulated (7) movable enforcement.Have with one voice (8) at the first binding clip (3) and the second binding clip (4) face of joining, (8) are joined and are formed by the first inner arc (9), the second inner arc (10) with one voice, and the first inner arc (9), the second inner arc (10) have teeth.The first binding clip (3), the second binding clip (4) inner face face of joining have boss (5), groove (6) to join, boss (5) the size high low dimensional concavo-convex with groove (6) is by intermeshing or separate adaptive and make, it is all interchangeable that its boss (5) or groove (6) are opened in the inner face of the first binding clip (3) and/or the second binding clip (4), and one side in office arranges all can.Boss (5) wing should repair round and smooth, the thorn that do not become mildewed, and groove (6) does not have wing's burr yet.

Embodiment 3, with reference to accompanying drawing, its general structure forms also with reference to embodiment 1, but the boss (5) of joining at the first binding clip (3), the second binding clip (4) inner face has teeth, groove (6) has teeth to be engaged with, and can strengthen like this clamping force, and multiple clamping points form netted joint.
