Abstract
The invention discloses a kirschner wire bending device. the device comprises a circular straight-rod hand rod, a handle is arranged at one end of the hand rod, two U-shaped snapping grooves formed and produced integrally with the hand rod are formed in the other ends, and the two U-shaped snapping grooves are vertical to form a cross U-shaped snapping groove. Two bending devices are required to be matched to be used, and during usage, a kirschner wire is sleeved in the U-shaped snapping groove of the first bending device and is held tightly; meanwhile, the kirschner wire is sleeved in the second bending device which is needed to be adjacent to the first bending device, the position of the first bending device is kept unchanged, a T-shaped handle of the second bending device is rotated clockwise or anticlockwise, bending can be performed through two hands by one person or single hands of two persons, the kirschner wire tail can be bent lightly, and the maximum bending angle can reach 180 degrees. Displacement of the kirschner wire tail can be prevented after the first bending device is held tightly; meanwhile, the two bending devices act on the kirschner wire simultaneously, and a couple action is provided; a pry bar point only acts on the kirschner wire bending point and cannot produce shearing force on the fracture end, so that re-displacement of fracture blocks can be prevented.
Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of Kirschner wire bending device.
Background technology
In the operative treatment of fracture, often application Kirschner wire fixation fracture.Need, by the bending of Kirschner wire backshank, to prevent Kirschner wire to be shifted after fixing end.Traditional method is two people's synergetic approaches, and a people clamps with needle-nose pliers, and another carries out bending, and two people must exert oneself simultaneously, and power thrusts is contrary, forms couple, just can bending Kirschner wire backshank smoothly.Sometimes need repeatedly to carry out, easily cause Kirschner wire metal fatigue and displacement fracture, affect surgical effect and there is hidden danger.Particularly periarticular fracture, more need accurate, stable reset and fix, therefore Kirschner wire bending is particularly important.Other lever volumes are comparatively large simultaneously, are difficult to insert operation near Minor articulus, affect the scope of application.
Summary of the invention
The present invention, in order to solve the problems of the technologies described above, provides a kind of Kirschner wire bending device, achieves the bending to Kirschner wire, this lever make simple, with low cost, be especially convenient to small space use, be easy to use at clinical expansion.
The present invention is achieved through the following technical solutions:
A kind of Kirschner wire bending device, it is characterized in that, comprise circular straight-bar hand lever, one end of hand lever is provided with handle, and the other end is provided with two U-shaped draw-in grooves of the one-body molded making with hand lever, and two U-shaped draw-in grooves vertically form the U-shaped draw-in groove of " ten " word mutually.
Described handle, hand lever and U-shaped draw-in groove adopt medical stainless steel material to make.
Described medical stainless steel material hand lever and medical stainless steel material handle form " T " font structure.
The draw-in groove width of described U-shaped draw-in groove is 1mm ~ 4mm, is highly 2mm ~ 6mm, wherein, the width of two U-shaped draw-in grooves on hand lever, highly different.
In two described U-shaped draw-in grooves, the draw-in groove width of a U-shaped draw-in groove is 4mm, is highly 5mm, and the draw-in groove width of another U-shaped draw-in groove is 2mm, is highly 3mm.
Compared with prior art, the present invention has following useful technique effect:
Lever of the present invention need 2 with the use of.After first first lever being inserted in Kirschner wire, closely hold Kirschner wire; Meanwhile, the second lever next-door neighbour first is inserted in Kirschner wire, keeps the first lever position motionless, clockwise or rotate counterclockwise the T-shaped handle of the second lever and single both hands or double one hand can carry out bending.Can bending Kirschner wire backshank like a cork, and bending angle is maximum can to 180 degree.First lever holds closely, can avoid Kirschner wire displacement; Meanwhile, because 2 lever act on Kirschner wire simultaneously, be force couple role; Ripping bar point only acts on Kirschner wire bending point, can not produce shearing to fracture end, therefore can not cause the displacement again of sclerite.
This apparatus fabricate is simple, with low cost, be convenient to small space especially uses, and is easy to use at clinical expansion.
Accompanying drawing explanation
Fig. 1 is Kirschner wire bending device structural representation provided by the invention;
Fig. 2 is that Kirschner wire bending device provided by the invention faces structural representation;
Fig. 3 is the left TV structure schematic diagram of the Kirschner wire bending device provided of the present invention.
Wherein: 1 is hands handle; 2 is hands bar; 3 is U-shaped draw-in groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See Fig. 1, a kind of Kirschner wire bending device, comprise the handle 1, hand lever 2 and the U-shaped draw-in groove 3 that adopt high-strength medical stainless steel to make, hand lever 2 is circular straight-bar hand lever, one end of hand lever 2 is provided with handle 1, and described medical stainless steel material hand lever 2 forms " T " font structure with medical stainless steel material handle 1.Hand lever 2 other end is provided with the one-body molded making of hand lever 2 and orthogonal two U-shaped draw-in grooves 3.Described two U-shaped draw-in grooves 3 form " ten " word draw-in groove.Wherein, the draw-in groove width of described U-shaped draw-in groove 3 is 1mm ~ 4mm, is highly 2mm ~ 6mm, wherein, the width of two on hand lever 2 U-shaped draw-in grooves 3, highly different.
Concrete, in two U-shaped draw-in grooves 3, the draw-in groove width of a U-shaped draw-in groove 3 is 4mm, is highly 5mm, and the draw-in groove width of another U-shaped draw-in groove 3 is 2mm, is highly 3mm, the Kirschner wire bending of reply different-diameter and holding.
It should be noted that, this Kirschner wire bending device can be used as holder, during use need 2 lever with the use of.Wherein, lever is T-shaped, high-strength medical stainless steel, and head end is U-shaped cross clamping groove, is respectively 2,4mm.
Use procedure of the present invention:
Lever hold concurrently holder need 2 with the use of.After first U-shaped for first lever draw-in groove being inserted in Kirschner wire, closely hold Kirschner wire; Meanwhile, second lever next-door neighbour first lever is inserted in Kirschner wire, keeps the first lever position motionless, clockwise or rotate counterclockwise the T-shaped handle of the second lever and single both hands or double one hand can carry out bending.Can bending Kirschner wire backshank like a cork, and bending angle is maximum can to 180 degree.First lever holds closely, can avoid Kirschner wire displacement; Meanwhile, because 2 lever act on Kirschner wire simultaneously, be force couple role; Ripping bar point only acts on Kirschner wire bending point, can not produce shearing to fracture end, therefore can not cause the displacement again of sclerite.
