Abstract

A Kirchner needle bending device belongs the technical field of orthopaedics surgical equipment. The utility model relates to a needle holder, the structure is that the needle holder is a rigid, hollow long tubular sleeve whose end is open and is provided with loose matching gap with the Kirchner needle; the other end of the sleeve is fastened at the top of the handle. The long tubular sleeve is longer than that of the Kirchner needle exposed of the bone. The positive effect of applying the utility model is that the Kirchner needle is clinched and then bent, the operator will be concentrated and nervous; nowadays, the Kirchner needle exposed of the bone will be sleeved and then bent, reducing the unnecessary energy and action in the operation, and the energy can be concentrated on the crucial position of the operation; moreover, the bending position of the Kirchner needle can closely contact the bone surface, and the bending effect is fine; the utility model is a practical design in the orthopaedics operation.

Description

A kind of Kirschner wire lever

Technical field

Belonging to the surgical operating instrument technical field, exactly is a kind of bone surgery set.

Background technology

After the reduction of the fracture, often adopt the fixed method of Kirschner wire to fix adjacent two or some sclerites, the Kirschner wire afterbody that exposes at bone surface then needs to be cut off.Before cutting off the Kirschner wire afterbody, generally need earlier to carry out bending to Kirschner wire at the intersection of surface of bone and Kirschner wire, sting out skin or submerge surface of bone and can't take out from now in case stay the backshank of bone surface.Normal at present application needle holder or pliers are finished the work of bending, often relatively require great effort, and owing to the width of needle holder or pliers itself stops, make the bending part of Kirschner wire can't be close to surface of bone, cause the afterbody of Kirschner wire to be projected on surface of bone and to push up skin.

Summary of the invention

This utility model provides a kind of machine tool simple in structure, and the bending that makes Kirschner wire was both easily convenient, again can be fully and a kind of Kirschner wire lever of surface of bone applying.

The technical scheme that this utility model is taked:

A kind of Kirschner wire lever comprises a needle holder, and its scheme is: needle holder is the elongated tubular sleeve that a rigidity, hollow, open-ended and Kirschner wire have the loose fit gap, and the telescopic other end is fastened on the top of the handle of managing for hands.The elongated tubular sleeve is longer than and is exposed at the outer Kirschner wire length of bone.

Good effect behind enforcement this utility model is:

Be originally and use pliers, will vise Kirschner wire earlier, then vise under the state bending of reuse power it, concentrate and nervous; As long as after nowadays putting the Kirschner wire that exposes outside bone, stoop smoothly and get final product, reduced inessential energy and the action in the operation technique, energy can be concentrated to be used to the key position of performing the operation; And can make the bending part of Kirschner wire be close to surface of bone again, bending is effective.

The specific embodiment

Now the utility model is described in further detail in conjunction with the accompanying drawings

A kind of Kirschner wire lever has a needle holder, and its structure is: needle holder be a rigidity, hollow, open-ended 2 with Kirschner wire 4 the elongated tubular sleeve 1 in loose fit gap is arranged, the telescopic other end is fastened on the top of the handle of managing for hands 3.Elongated tubular sleeve 1 is longer than and is exposed at the outer Kirschner wire length of bone.As long as after the Kirschner wire lever put the Kirschner wire that exposes outside bone, stoop smoothly and get final product during concrete the use, as shown in Figure 2.

Claims

1. Kirschner wire lever, comprise a needle holder, it is characterized in that: needle holder be a rigidity, hollow, open-ended (2) with Kirschner wire (4) the elongated tubular sleeve (1) in loose fit gap is arranged, the telescopic other end is fastened on the top of the handle of managing for hands (3).

2. a kind of Kirschner wire lever according to claim 1 is characterized in that: described elongated tubular sleeve (1) is longer than and is exposed at the outer Kirschner wire length of bone.
