Abstract
The utility model discloses a Kirschner pin with a central hole on the tail end, belonging to a surgery medical device, in particular to a fitting for a bone drill. The Kirschner pin with a central hole on the tail end comprises a pin tip and a pin bar. The structure is that the tail end of the pin bar far from the pin tip is provided with a longitudinal central hole; the diameter of he central hole is 0.3-1.5 mm, and the depth is 3-20 mm. The tail end of the novel Kirschner pin provided with a central hole can be fixed to an electronic auger for drilling on bones just like a common Kirschner pin. The drill bit is taken off from the Kirschner pin after penetrating the bone, and the steel wire is inserted into the central hole at the tail end of the Kirschner pin. With the derivation of the Kirschner pin, the steel wire penetrates into the bone hole; the surrounding soft tissue can not be damaged because the diameter of the steel wire is smaller than the diameter of the Kirschner pin, and thus patient's pain caused by the operation can not be increased.
Description
Affiliated technical field
This utility model belongs to surgical medical equipment, particularly the adnexa of bone drill.
Background technology
Kirschner wire is the apparatus that is used to hole in the clinical orthopaedics operation, during use the operator should be earlier with Kirschner wire in the boring of human body affected part, and then wear in the hole of having bored with other apparatus and to draw steel wire.This tends to occur the problem that the size of being holed and other apparatus of wearing steel wire do not match, the damage that causes incuring loss through delay operating time or increase wound surface.Chinese patent CN2378005Y discloses a kind of straight formula orthopedic kirschner pin that imports steel wire, and its technical scheme is, laterally has an aperture that can penetrate steel wire at the afterbody of Kirschner wire shank.The problem that the size that this scheme has solved boring and other apparatus of wearing steel wire do not match, but steel wire will bend to vertically after the afterbody transverse holes penetrates, because bending section is thicker, still has the possibility that increases the wound surface damage when passing boring with Kirschner wire.
Summary of the invention
The purpose of this utility model provides a kind of above-mentioned shortcoming that overcomes, and can penetrate the technical scheme that steel wire does not damage the novel Kirschner wire of wound surface again more easily.
The technical solution of the utility model is, a kind of Kirschner wire of tail end band centre bore comprises needle point, shank, and its structure is: away from the tail end of needle point a longitudinal center hole is arranged at shank.
The diameter of centre bore is 0.3-1.5mm, and the degree of depth is 3-20mm.
The diameter of preferred centre bore is 0.5-0.8mm, and the degree of depth is 5-8mm.
The beneficial effects of the utility model are, because the tail end of the novel Kirschner wire that the utility model proposes has centre bore, can equally with common Kirschner wire be fixed on the electric drill and on bone, punch, after penetrating sclerotin drill bit is unloaded from Kirschner wire, steel wire is inserted the centre bore of Kirschner wire tail end, and along with the derivation of Kirschner wire, steel wire pierces into the bone hole, so the invar filament diameter is less than the soft tissue of Kirschner wire around can not damaging, thereby a not therefore operation and increase patient's misery.This utility model is simple in structure, and is easy to use, is applicable to that all kinds of hospitals use in need be with the bone surgery of wearing steel wire after the Kirschner wire punching.
