Description
Technical field
This utility model relates to a kind of bone surgery medical apparatus and instruments, is specifically related to a kind of Kirschner wire tail end lever.
Background technology
The application of Kirschner wire in Orthopedic Clinical operation is very extensive, as the surgical menopause of hands, sufficient fracture dislocation, the internal fixtion etc. of extremity setting board of skeleton end fracture.In operation, the bending problem of Kirschner wire tail end annoyings bone surgery doctor always.
1909, this formula pin was improved as Kirschner wire by Martin Kirschner first.Although Kirschner wire is the reduction of the fracture fixedly provide many convenience, but Kirschner wire tail end also brings many common complications, as Kirschner wire displacement, tail end excitation soft tissue, stab out skin surface, even formed infect etc. happen occasionally, Kirschner wire tail end bending problem becomes a great problem, affect surgical effect and there is hidden danger, therefore Kirschner wire bending is particularly important.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of Kirschner wire tail end lever, and easy to operate, bending easily, is not easily shifted the withdraw of the needle, avoids the excitation of tail end soft tissue, infection etc.
Kirschner wire tail end lever described in the utility model, formed by left and right sides clamp handle cross-articulation, one end of clamp handle is provided with sleeve, sleeve is provided with opening, opening is towards the side of two clamp handle centrages, and the other end of clamp handle is provided with holds handle ring, and the handle ring place of holding of left and right clamp handle is equipped with band tooth locking bar, two band tooth locking bars engage each other, hinged place and the clamp handle bending forming V-shape held between handle ring.
Lever hold handle ring holding for medical worker, sleeve is used for the bending of Kirschner wire tail end, concentrates, so opening is towards side because sleeve side during bending is stressed, prevent stress from concentrating and damage lever, realized the fine setting of sleeve diameter by adjustment belt tooth locking bar.
The bending angle scope of described V-arrangement bending part is 20 °-40 °.
The inside diameter ranges of described sleeve is 0.5mm-3mm, is applicable to various sizes model Kirschner wire.
The length range of described sleeve is 5mm-8mm, meets the length of Kirschner wire tail end bending.
Operation principle and process:
In operation, Kirschner wire is accurately squeezed in bone behind precalculated position, Kirschner wire is exited 5mm, then use fixation clamps fixation Kel's needle tail end.After fixing, the sleeve of lever is inserted in Kirschner wire tail end, is about 10mm place at distance surface of bone and Kirschner wire tail end is fractureed, by predetermined direction by disposable for Kirschner wire pre-bending to 160 °-170 °, remove sleeve.Finally, press from both sides the tail end after bending to 180 ° by fixation clamps, be then driven in sclerotin along Kirschner wire direction by tail end, Kirschner wire tail end bending arch section flushes with surface of bone.
Because of visual area soft tissue stop do not reach pre-bending angle time, the sleeve of the lever of band V-arrangement bending can be reversed 180 ° and use, tail end pre-bending angle can be reached.
The beneficial effect that this utility model is compared with prior art had is:
Kirschner wire tail end lever reasonable in design, easy to operate, bending easily, is not easily shifted the withdraw of the needle, avoids the excitation of tail end soft tissue, infection etc.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation;
Fig. 2 is side-looking clamp handle V-arrangement bending structure schematic diagram.
In figure: 1, hold handle ring; 2, tooth locking bar is with; 3, clamp handle; 4, sleeve; 5, hinged place; 6, V-arrangement bending part; 7, opening.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As depicted in figs. 1 and 2, Kirschner wire tail end lever is formed by left and right sides clamp handle 3 cross-articulation, one end of clamp handle 3 is provided with sleeve 4, sleeve 4 is provided with opening 7, opening 7 is towards the side of two clamp handle 3 centrages, and the other end of clamp handle 3 is provided with holds handle ring 1, and handle ring 1 place of holding of left and right clamp handle 3 is equipped with band tooth locking bar 2, two band tooth locking bars 2 engage each other, hinged place 5 and the clamp handle 3 bending forming V-shape held between handle ring 1.
The bending angle of V-arrangement bending part 6 is 30 °.
The inside diameter ranges of sleeve 4 is 0.5mm-3mm.
The length of sleeve 4 is 6mm.
Kirschner wire is accurately squeezed in bone behind precalculated position, Kirschner wire is exited 5mm, then use fixation clamps fixation Kel's needle tail end in using by operation.After fixing, the sleeve 4 of lever is inserted in Kirschner wire tail end, is about 10mm place at distance surface of bone and Kirschner wire tail end is fractureed, by predetermined direction by disposable for Kirschner wire pre-bending to 160 °-170 °, remove sleeve 4.Finally, press from both sides the tail end after bending to 180 ° by fixation clamps, be then driven in sclerotin along Kirschner wire direction by tail end, Kirschner wire tail end bending arch section flushes with surface of bone.
Because of visual area soft tissue stop do not reach pre-bending angle time, the sleeve 4 of the lever of band V-arrangement bending can be reversed 180 ° and use, tail end pre-bending angle can be reached.
Clinical practice shows, and seldom occurs Kirschner wire displacement with the Kirschner wire tail end of this lever process, exits the excitation diabrosis of strong-willed soft tissue and infection etc.
