Abstract

The invention discloses a pair of Kirschner needle bending pliers. The Kirschner needle bending pliers comprise a first plier handle, a second plier handle, a first plier head, a second plier head, a boss, a groove, a hinge, a crossed opening, a first inner arc, a second inner arc and a plier body. The Kirschner needle bending pliers are characterized in that the plier body is provided with the first plier handle and the second plier handle, the first plier handle and the second plier handle are hinged in an overlapping mode through the hinge, the first plier head is arranged at the front end of the second plier handle, the second plier head is arranged at the front end of the first plier handle, the boss is arranged on the inner face of the first plier head, the groove is formed in the second plier head, the boss is clamped in the groove and matched with the groove, the crossed opening is formed in the connected face of the inner face of the end of the first plier head and the inner face of the end of the second plier head, and the first inner arc and the second inner arc are connected to form the crossed opening. The upper face and the lower face of the crossed opening are through to form a hole opening, the first inner arc and the second inner arc of the crossed opening are provided with teeth, the pliers are used for the surgical operation and the orthopedic operation and can easily bend a Kirschner needle by 90 degrees, the bending pliers are retreated in the direction of the bent Kirschner needle, and the Kirschner needle is cut short by shear pliers so as to be buried subcutaneously.

Description

A kind of Kirschner wire folding forceps

?

Technical field

The invention 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 object of the present invention is to provide and a kind ofly overcome 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 invention 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.

Advantage of the present invention be Kirschner wire like a cork bending at an angle of 90, along the Kirschner wire direction of bending, exit folding forceps, with scissor forceps, cut short Kirschner wire and be embedded in subcutaneous.Laborsaving, accurate, effective.

accompanying drawing explanation:

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.

The specific embodiment

Below in conjunction with accompanying drawing, the invention will be 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 fixedly draw point bending of ossiculum piece or little tubular bone and all more difficult to the bending of about 1cm minute hand tail of the abundant place of soft tissue.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 comprised 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, its using method of opening binding clip and grip objects is also with reference to the using method of existing electricians' plier, 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.At the first binding clip (3) and the second binding clip (4) face of joining, have with one voice (8), (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) made by intermeshing or separated adaptation, 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), one side in office, arrange and 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, and 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 clamping force like this, and a plurality of clamping points form netted joint.
