Description

Medical winder

Technical Field

The utility model relates to medical equipment, in particular to a medical winder used for bundling and fixing bones.

Background

In the prior art, bones need to be bundled and fixed in many orthopedic operations, and steel wires or silk threads need to be wound around the bones before the bundling and the fixing. At present, a winder head is generally used as a winder with a tubular arc structure, when the winder is used, the winder head firstly bypasses a skeleton, then a steel wire or a silk thread passes through the winder head, and the winder head is withdrawn, so that the steel wire can bypass the skeleton; however, the silk thread is too soft and can not directly pass through the head of the winder, and the silk thread guide wastes time and labor; and the winder head is tubular, the tip is blunt, and the resistance is large when surrounding the bone, and the surrounding is difficult. In addition, a frequently used winder is an arc-shaped structure with a hole at the front end of a winder head, when the winder is used, the winder head is firstly wound around a skeleton, then a steel wire or a silk thread passes through the hole of the winder head, the winder head is drawn back, the steel wire or the silk thread can be wound around the skeleton, the silk thread and the steel wire can be guided, but the operation is difficult when the steel wire or the steel wire passes through the hole, and particularly, the operation is more difficult to pass the silk thread or the steel wire through the hole when the operation field is unclear, so that the time is wasted.

During the surgical operation, the medical staff are highly concentrated and extremely tired, and the shorter the operation time is, the more beneficial the patient is. The winding time of the steel wire or the silk thread is saved, namely the time for binding and fixing the skeleton is shortened, namely the operation time is shortened, so that the medical steel wire or the silk thread winder which can quickly and labor-saving wind the skeleton and save time and labor when the silk thread or the steel wire is connected with the winder is needed. Which is a disadvantage of the prior art.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a technical scheme of a medical winder, which is simple in structure, quick and labor-saving in operation, aiming at the defects in the prior art.

The technical scheme adopted by the utility model is as follows: the utility model provides a medical spooler, includes the spooler body, characterized by: the winder body include winder head and winder body, the shape of winder head is arc, the one end of winder body even have handle, characterized by: the tip of the winder head is provided with a threading groove, and the opening direction of the threading groove is opposite to the direction of the tip of the winder head.

Preferably, one end of the winder body is connected with the handle through a screw.

Preferably, a blind hole with a regular hexagon section is formed in one end, connected with the winder body, of the handle.

Preferably, the cross-sectional shape of the connection part of the winder body and the handle is a regular hexagon.

Preferably, the circular arc-shaped structure of the winder head has a central angle of 225 degrees.

Preferably, the threading groove is located on an inner side surface of the winder head.

Preferably, the threading groove is located on an outer side surface of the winder head.

Preferably, the distance between the threading groove and the tip of the winder head is 5-10 mm.

Preferably, the depth of the threading groove is 0.1-2 mm.

The utility model has the beneficial effects that:

1. the tip of the winder head is provided with a threading groove, and after the winder head winds the skeleton, the threading groove is hung with the silk thread or the steel wire and then pulled back, so that the silk thread or the steel wire can wind the skeleton. Because silk thread or steel wire need not pass the hole, so can touch the threading groove with the hand convenience when the art field is unclear, hang the line simply labour saving and time saving.

2. The winder body and the handle can be separated, so that batch manufacturing can be carried out, and the production cost is reduced; during operation, different winder bodies can be replaced according to needs, and the winder bodies are installed simply, conveniently and quickly.

3. Through the rational design of the structure of the tip of the winder head, the winder has small resistance when surrounding the skeleton, saves time and labor, is easy to expose the skeleton and greatly saves the operation time.

4. The handle and the winder body are fixed through the screw, the contact area of the handle and the winder body is large, the fixing is reliable, and the winder head can rotate greatly under the condition that the handle is fixed.

In the figure, 1-1 is a threading groove, 1-2 is a threading groove, 2 is a tip, 3 is a winder head, 4 is a winder body, 5 is a screw, 6 is a handle, and 7 is a blind hole.

Detailed Description

In order to clearly illustrate the technical features of the present solution, the following explains the present solution by a specific embodiment in combination with the accompanying drawings.

As can be seen from the attached drawings, the medical winder comprises a winder body, wherein the winder body comprises a winder head 3 and a winder body 4, and one end of the winder body 4 is connected with a handle 6 through a screw 5. The handle 6 is connected with the winder body 4, a blind hole 7 with a regular hexagonal section is formed in one end of the handle, and the section of the connection part of the winder body 4 and the handle 6 is in a regular hexagonal shape. When the winding device needs to surround the bone, the winding device body is firstly inserted into the blind hole 7 of the handle, and then the screw 5 is screwed, so that the winding device body is fixed on the handle 6.

The shape of the winder head 3 is circular arc, the central angle of the circular arc structure is 225 degrees, the tip 2 of the winder head 3 is provided with a threading groove 1-1, the threading groove 1-1 is positioned on the inner side surface of the winder head 3, and the opening direction of the threading groove 1-1 is opposite to the direction of the tip 2 of the winder head.
