Description

Abdominal wall suspension double suture for laparoscope

Technical Field

The invention relates to a material for laparoscopic surgery.

Background

Uterine prolapse is a common clinical disease, a prolapsed uterus and an abdominal wall are connected and fixed in a bridge mode by adopting a laparoscopic linear suspension method, currently adopted sutures are long, and a middle mesh part (patent number: CN201320016501. X) of the suture with long length needs to be sutured from the head ends of the suture, or a middle point single line part (patent number: CN 201610518192.4) of the suture with long length needs to be sutured from the head ends of the suture, and the middle part of the suture is fixed, so that the suturing operation is difficult because the suture is too long and a plurality of sutures are sometimes needed. More importantly, as the laparoscopic surgery is limited by the endoscopic field, the required length of the suture is very long, even a plurality of sutures appear in the abdominal cavity at the same time, the suture with very long length is usually self-phase or intertwined and knotted in the abdominal cavity, thus seriously interfering the smooth implementation of the surgery.

In order to firmly suture and fix the cervix and prevent the linear cutting action, one of the methods which can be selected is to suture through the cervix for a plurality of times at the cervix part to form a plurality of lines which are arranged to penetrate through the cervix tissue, thereby weaving the net to form a resultant force. However, at present, single-thread suture and middle-section suture are adopted, if the cervical tissue is woven into a net by itself and needs to be sutured for multiple times, only one needle can be sutured, and one thread, namely one needle and one thread, is implanted, and because the thread section for suturing and fixing is located at the middle section of the suture, the thread for suturing, pulling and drawing at each time is very long, so that the suture is time-consuming and labor-consuming and limited, and at present, the linear cutting effect for preventing the suture is achieved by means of mesh assistance in clinical practice in order to avoid the problem.

In addition, the suture adopted at present needs to be sewed from the end of the thread to the middle mesh part of the suture with long length (patent number: CN201320016501. X) or needs the middle point single line part of the suture with long length (patent number: CN 201610518192.4), the used suture needs to be preset with a middle point, the manufacturing process is complicated and the price is high.

Disclosure of Invention

In order to make up for the defects of the prior art, the invention discloses a double-suture suspended on the abdominal wall for laparoscope, which is characterized by comprising a suture needle, a suture, a protective sheath and an anti-slip knot. The suture needle is connected with the middle point of the suture, the suture is of a linear structure, one end of the suture, which is connected with the suture needle, is a suture head end, one end of the suture, which is far away from the suture needle, is a suture tail end, the suture between the suture head end and the suture tail end is a line a and a line b respectively, the periphery of the suture is a protective sheath, the protective sheath is of a tubular structure, has toughness and elasticity and is capable of automatically resetting, the suture penetrates through the protective sheath, the suture needle and a part of the suture are arranged on one side of the protective sheath, the anti-slip knot is arranged on the other side of the protective sheath. After the suture proximal end is fixed on the cervix under the laparoscope by adopting suture needles for suturing, the forceps clip pulls the tail end of the suture to reach the outside of the abdominal cavity, the anti-slip knot is cut off, the protective sheath is pulled outwards to be removed, and then the line a and the line b in the suture are mutually knotted and fixed on the abdominal wall, or the line a and the line b are respectively fixed on the point a and the point b of the abdominal wall by self-knotting.

The invention adopts the following technical scheme to solve the technical problems

1. An abdominal wall suspension double suture for laparoscope is characterized by being provided with a suture needle, a suture, a protective sheath and an anti-slip knot;

2. a double-suture suspended on the abdominal wall of a uterus for laparoscope is characterized in that the double-suture suspended on the abdominal wall is provided, a suture needle is connected with the midpoint of the suture, the suture is of a linear structure, the end of the suture connected with the suture needle is a suture head end, the end of the suture far away from the suture needle is a suture tail end, and the suture between the suture head end and the suture tail end is an a-line and a b-line respectively;

3. a suspended double suture line for the abdominal wall of uterus for laparoscope features that it has a tubular protecting sheath, which has toughness and elasticity and can automatically reset. The thread a and the thread b penetrate through the same protective sheath together to form a single-protective-sheath double-suture thread; the thread a and the thread b respectively penetrate through the independent protective sheaths to form a double-protective-sheath double-suture thread;

4. a double-suture for suspending the abdominal wall of uterus for laparoscope is characterized by comprising an anti-slip knot, wherein the anti-slip knot is fixedly connected with the far end of the suture.

After adopting above-mentioned technical scheme, compare with prior art, have following advantage:

1. the suture is sewn from the head end of the suture, and the head section of the suture is taken for fixing, so that the suture with long length is prevented from being drawn repeatedly for a long distance;

2. the double-suture is adopted to suture and penetrate through the cervical tissue, a net is woven in the cervical tissue, and one needle is used for double-suture, so that the work is doubled;

3. the protective sheath has toughness and is stiff, so that the suture lines are effectively prevented from self-phase or self-winding mutually;

4. there is no longer a need to apply a separate mesh sheet material to prevent linear cutting;

5. the middle point single line segment of the suture line does not need to be established in advance, and the manufacturing process is simplified on the premise of ensuring the equal length of the line a and the line b.

6. The midpoint net sheet of the suture is not needed to be established in advance, and the manufacturing process is simplified.
