Description

Simple meniscus stitching instrument from inside to outside

Technical Field

The invention belongs to the technical field of meniscus stitching devices, and particularly relates to a simple meniscus stitching device from inside to outside.

Background

The meniscus has important physiological functions for the knee joint, and meniscus suture can save the damaged meniscus to the maximum extent, relieve the pain symptom of the knee joint and relieve the rapid wear of the knee joint caused by the meniscus loss of the knee joint.

The existing meniscus suturing technology is divided into three types, one type is full-internal suturing, namely the current mainstream of arthroscopic surgery, meniscus is sutured in the arthroscope in the whole process, and a disposable meniscus suturing device is used for suturing; one is sewing from outside to inside; the last is stitching from inside to outside. Since the latter two tools are less convenient and improper handling is prone to scarring at the suture site, the most common meniscal suturing technique in the clinical setting at this stage is meniscal stapler direct arthroscopic total internal suturing.

These meniscal staplers still exist in a number of places worth improvement:

1. relating to the problems of patent right and import, the price is high, and the medical insurance reimbursement proportion is low.

2. All are disposable consumables, and the cost is higher.

3. The disposable meniscal stapler must be hollow, low in hardness and flexible because the thread is in the middle.

4. Disposable meniscal staplers are mostly angle-less and suturing of meniscal anterior horn lesions is relatively difficult.

5. The disposable meniscal stitching instrument is designed to be used once, and once stitching is slightly wrong, one stitching instrument needs to be opened again.

Disclosure of Invention

In order to solve the technical problem, the invention provides a simple meniscus stitching instrument from inside to outside, which can be repeatedly used, is simple and convenient to operate, and can reduce the price of a stitch of meniscus by 10-15 times compared with the existing level.

The invention relates to a simple meniscus stitching instrument from inside to outside, which comprises: a suture needle, a handle and a round needle; the handle is connected with the suture needle; the suture needle comprises a needle body and a needle head connected with the needle body, the needle head is of a solid structure, and a hole for threading a suture thread is formed in the needle head; the round needle is one, and the pointed end of the round needle is blunt.

Preferably, in the above-mentioned technical solution of the simple meniscus suture instrument from inside to outside, the circular needle is in the shape of a half arc, and the cross section is circular.

Preferably, in the above-mentioned technical scheme of the simple meniscus suture instrument from inside to outside, the included angle between the needle head and the needle body is 0 to 30 °.

The simple meniscus stitching instrument from inside to outside is used for solving the problem of high stitching instrument cost, can be recycled and provides a patient with a choice right. Secondly, the needle head of the suture needle of the meniscus suture instrument only needs one hole for threading a suture thread, and the needle head is basically of a solid structure and hard enough and not easy to bend in joints.

Detailed Description

The invention provides a simple meniscus stitching instrument from inside to outside, which can be repeatedly used, is simple and convenient to operate, and can reduce the price of stitching a meniscus by 10-15 times compared with the existing level.

The following detailed description of the present invention will be described with reference to the accompanying drawings, which are provided for illustration purposes only and are not intended to limit the scope of the present invention.

As shown in FIGS. 1-4, the simple inner-to-outer meniscus stapler of the present invention comprises: a suture needle, a handle and a round needle.

The handle is connected with the suture needle, and the handle can be a wooden handle.

The suture needle comprises a needle body and a needle head connected with the needle body, and the included angle between the needle head and the needle body is 0-30 degrees. The needle head is of a solid structure, and a hole for threading a suture thread is formed in the needle head.

As shown in fig. 15, the round needle is one, and the sharp head of the round needle is blunt. The round needle is in a half arc shape, and the cross section is circular.

As shown in fig. 6 to 14, the simple meniscus stapler from inside to outside according to the present invention comprises the following steps:

the suture needle penetrates out of the skin from inside to outside through an arthroscope, and a prepared suture thread penetrates through a hole of the suture needle outside the body, wherein a certain length is reserved on both sides of the hole;

the suture needle brings the thread passing through the hole into the joint cavity, the suture thread is ensured to be always in the hole in front of the suture needle, the next needle insertion point is searched, and the meniscus is ready to be threaded for the second time;

determining the thickness of a needle insertion point, and enabling the meniscus suture needle with the thread to penetrate out of the skin from inside to outside to ensure that the meniscus suture thread passes through the meniscus;

taking out the meniscus suture needle, and reserving two thread ends outside the skin for treatment;

ensures that two outlets of the needle can be sutured at the same point, and ensures that the appearance of the skin is not involved. Removing the front end by using a large round needle provided with the needle to form a round needle with a blunt end, wherein a thread on one side passes through the round needle;

the blunt round needle with the thread end on one side passes through the subcutaneous deep layer and is tightly attached to the other thread end to be output, so that two thread tails are ensured to be output at the same point, and soft tissues are reduced as much as possible in the middle;

preparing to tie a knot;

knotting and tightening to firmly fix the meniscus;

the knotted skin is treated to ensure that no scar is left on the skin appearance. The invention can complete the half-moon plate sewing technology from inside to outside quickly with the aid of a tool.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
