Abstract

The utility model relates to a stair shape tracting needle fixing device, belonging to a medical instrument for traction therapy or fixed traction of human limbs after fractured. The utility model overcomes the defects of the existing tracting needle fixing devices that the tracting needle can not pass through occasionally, that slippage and inconvenient operation exist, etc. The success ratio and the accuracy of operative procedures are raised, the pain of patients is reduced, and the operation time is shortened. The device is composed of a tracting needle fixer, a traction bow body, a stair shape opening, a semicircular tracting needle channel and a fixing bolt. The utility model with the advantages of light weight, simple structure, convenient operation and low cost is practical, quick and simple.

Description

Stair shape tracting needle fixing device

Step pull needle holder is a kind of traction therapeutic after the human limb fracture or medical equipment of fixed traction of being used for.

Existing pull needle holder is airtight poroid, pull needle is by passing in the hole, because the deviation in position, build and traumatic condition or the operation, usually causing pull needle to pass from closed pore or to pass is obstructed, and need thread a needle again, not only increase misery, and brought many inconvenience to medical worker's work to patient.

This utility model is intended to propose a kind of step pull needle holder, defectives such as it has solved that existing pull needle holder can't make sometimes that pull needle passes, slippage or operation inconvenience, the success rate and the accuracy of operation technique have been improved, alleviated patient's misery, shortened operating time, very big application value has been arranged.

This utility model is finished like this:

Pull needle holder 6 one ends are individually fixed in an end of traction bow, about each one, the central part of holder bore 5mm fixedly needle track 3 1/3 place, one side sawing thereon become 1/2 of the oblique needle track half garden shape of open wide 5mm to form step, establish the set bolt of diameter 3mm so that make it fixed into and out of adjusting at the vertical of traction needle track according to the pull needle of different-diameter.

The utlity model has following advantage:

1, be not subjected to the restriction of pull needle length and thickness, the 2-5mm fine steel needle all is suitable for;

2, allow the deviation of needle angle in the operating process, do not influence traction effect, improved the success rate and the accuracy of traction operation;

3, be not subjected to the position, the restriction of build and traumatic condition is all applicable;

4, easy to operate, rapidly, simply,, pull needle slips into the traction needle track as long as being hung up suitable its step from opening part, regulate the width of traction bow, tighting a bolt gets final product.

The utility model is described in further detail below in conjunction with implementing legend:

Fig. 1 implements illustration for this utility model:

1, traction bow body 2, stepped openings 3, half garden shape traction needle track 4, set bolt 5, pull needle 6, pull needle holder

Traction bow body 1 connects pull needle holder 6, the fixedly needle track 3(side that is provided with diameter 5mm at the central part of pull needle holder 6 is seen), 1/3 place is designed to 1/2 of open wide 5mm45 ° of oblique needle track half garden shape and forms the sight of step 2(side on a side of fixing needle track 3); Be provided with the full tooth set bolt 4 of a diameter 3mm in the outside of stepped openings, pull needle 5 slips into half garden shape traction needle track 3 along its stepped openings formula arc groove.

Claims

1, step pull needle holder contains traction bow, set bolt, it is characterized in that being stepped openings formula arc groove in pull needle holder middle and upper part one side.

2, step pull needle holder according to claim 1, its feature is provided with half garden shape traction needle track at stepped openings formula arc trench bottom.
