Description

A kind of Kirschner wire bending device

Technical field

The utility model is related to technical field of medical instruments, and in particular to a kind of Kirschner wire bending device.

Background technology

Kirschner wire is the internal fixation material commonly used in a kind of bone surgery, and its specification is generally fixed to length for 20 centimeters Left and right, diameter are usually used in that Treat Hand Fracture is fixed and dislocation is fixed between 1～3.5 millimeter.Fixation terminate after need by Kirschner wire backshank bending, prevents Kirschner wire displacement and the excitation to tail end soft tissue, infection etc..Still no Kirschner wire bending at present Special implement, is typically two people cooperation in prior art, a people is clamped with nipper plier, and another carries out bending, and two people must be same When exert oneself, and power thrusts are conversely, coordinate difficulty big, it is sometimes desirable to repeatedly carry out just can smooth bending Kirschner wire backshank, easily Cause Kirschner wire metal fatigue and fracture to shift again, so that affecting knitting, pain is brought to patient.

Utility model content

For the deficiencies in the prior art, the utility model provides a kind of Kirschner wire bending device, its reasonable in design, behaviour Make convenient, bending easily, be difficult to shift the withdraw of the needle, it is to avoid the excitation of tail end soft tissue, infection etc..

For realizing object above, the utility model is achieved by the following technical programs：

A kind of Kirschner wire bending device includes left clamp arm and right clamp arm, the left clamp arm and right clamp arm chain connection, the left side The affixed solid torus in tong arm front end, the solid torus are provided with multiple circular pin holes, and the front end face of the right clamp arm has boss, described Boss is connected to hollow draw ring on right clamp arm, and the rear end of the left clamp arm and right clamp arm is arranged with holds handle ring, described to hold handle Band tooth clamp-buckle is equipped with ring, and two band tooth clamp-buckles are mutually twisted.

The circular pin hole number is 1-6.

The circular pinhole aperture is 1-3.5mm.

The circular pin hole number is more than 1, and the aperture in the plurality of hole is different.

The circular pin hole entrance is rounding corner structure.

The utility model reasonable in design, the handle ring of holding on bending machine are conveniently held, the hollow draw ring and reality on tong arm The bending that thimble acts synergistically for Kirschner wire tail end, during bending, cavity ring pushes down the tail end of Kirschner wire, with contact point as fulcrum Bending is carried out, and by adjusting the regulation for realizing bending radian with tooth clamp-buckle, the rounding corner structure of circular pin hole is easy to Kirschner wire Penetrate, easy to operate, bending is easy, be difficult to shift the withdraw of the needle, it is to avoid the excitation of tail end soft tissue, infection etc..

Description of the drawings

In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.

Fig. 1 is the structural representation of Kirschner wire bending device.

Fig. 2 is the profile of circular pin hole on Kirschner wire bending device.

Fig. 3 is right clamp arm upper end enlarged drawing on Kirschner wire bending device.

Specific embodiment

It is for making purpose, technical scheme and the advantage of the utility model embodiment clearer, new below in conjunction with this practicality Accompanying drawing in type embodiment, is clearly and completely described to the technical scheme in the utility model embodiment, it is clear that retouched The embodiment stated is a part of embodiment of the utility model, rather than the embodiment of whole.Based on the enforcement in the utility model Example, the every other embodiment obtained under the premise of creative work is not made by those of ordinary skill in the art are belonged to The scope of the utility model protection.

A kind of Kirschner wire bending device includes left clamp arm 1 and right clamp arm 2,2 chain connection of the left clamp arm 1 and right clamp arm, institute The affixed solid torus 3 in 1 front end of left clamp arm is stated, the solid torus 3 is provided with multiple circular pin holes 4, and pin hole entrance is rounding corner structure, Be easy to penetrating for Kirschner wire, its number is 1-6, and the aperture in multiple holes is different, aperture be respectively 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, the front end face of right clamp arm 2 have boss 6, and a hollow draw ring 5 is connected to right clamp arm by boss 6 On 2, hollow draw ring 5 can move in a circle, the bending that hollow draw ring 5 and solid torus 3 act synergistically for Kirschner wire tail end, bending When hollow draw ring 5 push down Kirschner wire, be arranged with as the rear end that fulcrum carries out bending, left clamp arm and right both sides with contact point and hold handle Ring 7 conveniently holds, and holds, and two band tooth clamp-buckles 8 are mutually twisted, and is realized by adjusting band tooth clamp-buckle The regulation of bending radian.The Kirschner wire bending device is rational in infrastructure, easy to operate, and bending is easy, be difficult to shift the withdraw of the needle, it is to avoid tail The excitation of end soft tissue, infection etc..

Above example only to illustrate the technical solution of the utility model, rather than a limitation；Although with reference to aforementioned reality Apply example to be described in detail the utility model, it will be understood by those within the art that：Which still can be to front State the technical scheme described in each embodiment to modify, or equivalent is carried out to which part technical characteristic；And these Modification is replaced, and does not make the essence of appropriate technical solution depart from spirit and the model of each embodiment technical scheme of the utility model Enclose.
