Abstract

The utility model relates to a novel Kirschner wire, which belongs to the field of medical instruments. The Kirschner wire comprises a wire point 1, a wire rod 2 and a wire tail 3, and is characterized in that the wire point 1 is tapered, a steel wire penetrating hole 4 is formed on the wire point 1 and is 1 to 1.5 mm in diameter, and in a knee joint crossed ligament fixing surgery, the steel wire can be guided to penetrate, thereby reducing tissue damage; and scales 5 are arranged on the wire rod 2, the minimal one of the scales 5 is 0.1 cm, and the scales can be used for controlling the depth that the wire enters accurately. The novel Kirschner wire has the advantages of simple structure and convenience in use; the depth that the wire enters can be accurately controlled, and the pain of a patient can be relieved; moreover, the novel Kirschner wire can serve as a steel wire guider during a surgical process, thereby reducing tissue damage.

Description

Novel Kirschner wire

Technical field: this utility model belongs to medical instruments field, particularly a kind ofly can accurately control depth of needle, alleviates patient's misery, and can in operation process, use as steel-wire inducer, alleviate tissue injury, novel Kirschner wire simple in structure, easy to use.

Background technology: it is one of orthopaedics modus operandi commonly used that the reduction of the fracture adds the Kirschner wire internal fixation, be mainly used in the internal fixation of fracture of long bone, as clavicular fracture, ulnar fracture, fracture of radius, fracture of tibia and fibula, children's's Fracture of femur etc., also can be used in some particular procedure middle punch, and then from the hole, pass steel wire, it is fixing to utilize steel wire to tie up, and as Patella fracture, cruciate ligaments of knee joint is torn internal fixation etc.At present, the Kirschner wire of clinical use does not have scale on the shank, in operation process, can not accurately control depth of needle, in some operation, bore a hole when introducing steel wire in addition, because steel wire must be soft, in penetrating process, direction is not easy to grasp, and causes operating time to prolong, damage to surrounding tissue increases, and brings bigger damage and misery to the patient.

Summary of the invention: the purpose of this utility model is to provide a kind of can accurately control depth of needle, alleviates patient's misery, and can use as steel-wire inducer in operation process, alleviates the novel Kirschner wire of tissue injury.

For achieving the above object, this utility model has been taked following technical scheme: this novel Kirschner wire, constitute by needle point, shank and backshank, and needle point is taper, needle point is provided with wire hole, the diameter of wire hole is 1-1.5mm, and in the cruciate ligaments of knee joint fixing operation, bootable steel wire penetrates, alleviate tissue injury, shank is provided with scale, and its minimum scale is 0.1cm, can be used to accurately control depth of needle.

This utility model, simple in structure, easy to use, can accurately control depth of needle, alleviate patient's misery, and can in operation process, use as steel-wire inducer, alleviate tissue injury, be a kind of ideal novel Kirschner wire.

Description of drawings: the utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

With reference to accompanying drawing 1,1, needle point, 2, shank, 3, backshank, 4, wire hole, 5, scale.

The specific embodiment: this utility model, be made with stainless steel material, constitute by needle point 1, shank 2 and backshank 3, needle point 1 is taper, and needle point 1 is provided with wire hole 4, and the diameter of wire hole 4 is 1-1.5mm, shank 2 is provided with scale 5, and the minimum scale of scale 5 is 0.1cm.

When using this utility model, earlier backshank 3 is installed on the medical rig, in the inserting needle process, in conjunction with the scale on the shank 25, accurately control depth of needle, in order to avoid cause unnecessary damage, if be used for guide wire, after boring is finished, steel wire is through on the wire hole 4, Kirschner wire is return and steel wire can be drawn along former road.
