Abstract

The utility model relates to a medical apparatus, in particular to a lower meniscus sewing needle of an arthroscope, which solves the problems that most of the existing sewing needles have complicated structures limited application range and are hard to operate. The lower meniscus sewing needle of a arthroscope comprises a needle handle, a needle body and an entire sewing needle of a needle tip, wherein the joint position of the needle body and the needle tip is provided with a needle hole; the needle tip bends towards one side; an included angle between the needle tip which bends towards one side and the needle body is 15 DEG, or 30 DEG, or 45 DEG. The utility model has the advantages of wire carrying by the needle tip, wire penetration outside a joint, simple, rapid and convenient operation, and reliability and little possibility of falling after sewing wire penetration. The design of the bending needle tip is suitable for sewing for different kinds of arthroscope damage at different positions. The utility model has the advantages of simple structure, low manufacture cost, wide application, simple and convenient operation, and easy master for operators.

Description

Arthroscope lower meniscus sewing needle

Technical field

This utility model relates to a kind of medical apparatus, exactly is arthroscope lower meniscus sewing needle.

Background technology

Meniscus injury is a common disease clinically, and along with deepening continuously that meniscus injury is studied, its treatment means is also perfect gradually.Previously, often adopt open meniscus to cut art treatment meniscus injury entirely, though the damage that causes knee joint to retrieve degenerative osteoarthritis appears, in short-term effect ideal very soon because understanding is not enough.Recent study is found: meniscus can increase the contact area in joint, disperses the load of articular cartilage; Reduce contact stress, absorb impulsive force; Strengthen the kinetic stability in joint; And the effects such as lubricated nutrition in joint, have great significance to keeping knee joint function, therefore meniscus injury at present often adopts meniscus to sew up the recovery technique treatment.

Recovery technique is sewed up in meniscus injury to be had: from inside to outside suturing skill (Inside-Out technology), ecto-entad suturing skill (Outside-In technology), complete in suturing skill (T-fix technology, FasT-Fix technology, can absorb meniscus screw technology, meniscus arrow technology etc.).Suturing skill abroad just rises at present in wherein complete, and short-term effect and preceding two kinds of methods are similar, and late result remains further to be observed and checking, and costs an arm and a leg, and complicated operation is higher to patient's specification requirement.Therefore the preceding two kinds of technology of domestic normal employing are carried out meniscal repairs at present, wherein because suturing skill is simple to operate from inside to outside, are easy to reasons such as grasp, are most widely used.Used since method is sewed up meniscus from inside to outside since Henning reported first in 1980, through nearly 30 years clinical practice, its suturing skill progressively be that numerous scholars accept and application.Yet the most complex structures of the sewing needle of present domestic use are difficult to operation, and scope of application limitation can not be sewed up the dissimilar meniscus injury of different parts, and cost an arm and a leg, the fundamental realities of the country that not too suitable China economy comparatively falls behind.

Summary of the invention

For solve the most complex structures of existing sewing needle, be difficult to operate, the problem of scope of application limitation, this utility model provide a kind of simple in structure, easy and simple to handle, be applicable to the novel arthroscope lower meniscus sewing needle that the dissimilar meniscus injuries of different parts are sewed up.

The concrete structure design is as follows:

Arthroscope lower meniscus sewing needle comprises the whole sewing needle of needle handle, needle body and needle point, and characteristics are:

The joint of described needle body and needle point is provided with pin hole.

Described needle point is to a lateral bending song, is 15 degree angles or 30 degree angle or miter angles to the needle point and the angle between the needle body of a lateral bending song.

Useful technique effect of the present utility model is embodied in following several aspect:

1, the needle point of arthroscope lower meniscus sewing needle is provided with pin hole, the needle point band wire, and threading outside the joint, convenience simple to operation, suture penetrates the firm difficult drop-off in back;

2, the needle point design has the bending of different angles, is applicable to the stitching of the dissimilar meniscus injuries of different parts.

3, needle body is elongated, and certain pliability is arranged, and has flexible in certain limit, cooperates the needle point of different angles, applicable to the stitching of the dissimilar meniscus injuries of different parts.

4, this utility model is simple in structure, and is cheap for manufacturing cost, widely applicable, and operation technique is easy, and the patient is easy to grasp.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment 1:

Arthroscope lower meniscus sewing needle comprise have needle handle 1, the whole sewing needle of needle body 2 and needle point 3, needle body 2 is provided with pin hole 4 with the joint of needle point 3.

Embodiment 2

Referring to Fig. 1 and Fig. 2, arthroscope lower meniscus sewing needle comprise have needle handle 1, the whole sewing needle of needle body 2 and needle point 3, needle body 2 is provided with pin hole 4 with the joint of needle point 3; Needle point 3 is to a lateral bending song, is 15 degree angles to the needle point 3 and the angle between the needle body 2 of a lateral bending song.

The sewing process of utility model sewing needle is described below:

Detect the position and the type of impairment of meniscus injury under the arthroscope, and select the meniscus sewing needle of different angles to insert in the joint space according to its position and type of impairment, penetrate the meniscus sewing needle from the meniscus tear injury, an and additional little otch outside the joint of corresponding position, sewing needle is passed, outside the joint, put on suture, see Fig. 3.The meniscus sewing needle of putting on suture outside the joint is drawn in intraarticular, see Fig. 4, wherein suture one end is stayed outside the joint, and the other end is drawn in intraarticular by the meniscus sewing needle.The sewing needle of band wire is passed to the joint once more in the meniscus tear place, see Fig. 5.Suture is withdrawed from pinprick, and sewing needle withdraws from meniscus, sees Fig. 6.Suture is tied a knot outside the joint, sees Fig. 7, finishes sewing process one time.Identical therewith, sew up the 2nd pin, the 3rd pin gets final product.
