Description

Liver suspension needle under laparoscope

Technical Field

The utility model belongs to the technical field of liver suspension needles, and particularly relates to a liver suspension needle under a laparoscope.

Background

The operation refers to the treatment of excision, suture and the like of a patient body by a doctor by using medical instruments, in the human body laparoscopic surgery, sometimes the liver can block the surgical field and interfere with the operation, at this time, the liver needs to be dragged, pulled and suspended, the liver suspension device is an operation auxiliary device for dragging, pulling and suspending the liver, and the existing liver suspension device in the laparoscopic surgery has the following problems in use:

1. the original straight needle needs to penetrate through liver (or uterus) tissues twice, and is knotted in vitro after penetrating through the abdominal wall twice, so that the injury to the abdominal wall and organs needing to be suspended and pulled is relatively large due to the two punctures, and when the needle is knotted in vitro, roving needs to be padded below the knotted part, so that the operation is inconvenient, and the body surface skin injury is easily caused.

2.2-0 type straight needle, which is actually used for intestinal anastomosis, has sharp needle point and is easy to puncture hepatic blood vessels to cause bleeding

The 3.2-0 type straight needle is a blood vessel suture and has a cutting effect on blood vessels of the liver, and when the body position is changed in the operation, the suture has the cutting effect, so that tissue bleeding is easily caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a laparoscopic liver suspension needle, which aims to solve the problem that the existing laparoscopic liver suspension needle in the background technology has relatively large damage to the abdominal wall and organs needing suspension and traction due to the existing liver suspension equipment in laparoscopic surgery, so that the skin on the body surface is easily damaged.

In order to achieve the purpose, the utility model provides the following technical scheme: liver suspends needle in midair under peritoneoscope, including blunt-headed needle, the outer wall welding of blunt-headed needle has the suture, the one end fixedly connected with needle tail hose of blunt-headed needle is kept away from to the suture.

Preferably, the material of suture is the suture of thick type absorbable suture or the thread of the firm silica gel material.

Preferably, the suture is made of high-elasticity materials.

Preferably, the blunt-ended needle is made of a shape and material similar to those of a liver needle.

Preferably, the needle tail hose is made of silica gel materials, and the blunt-ended needle is the same as the suture in diameter.

Preferably, the blunt-headed needle penetrates through the liver and the abdominal wall, the needle tail hose is clung to the outer wall of the liver, and the suture is fixedly connected with the abdominal wall through the mosquito clamp.

Compared with the prior art, the utility model has the beneficial effects that:

1. the blunt-head needle with the needle point designed like a liver needle can avoid blood vessels when passing through liver tissues, so that liver bleeding is avoided, and the damage to the liver caused by the fact that the existing suspension needle head is too sharp is reduced.

2. By using a suture that does not cut liver tissue, such as a thick absorbable suture or a strong silicone suture, which is a high-elasticity suture, the cutting effect of the suture on the liver tissue is reduced, and bleeding does not occur even when the body position is changed during surgery.

3. The blunt needle penetrates through the liver and the abdominal wall, when the blunt needle penetrates through liver tissues, blood vessels can be avoided, the liver can be prevented from bleeding, after the blunt needle penetrates through the liver and the abdominal wall, a needle tail hose is left in the abdominal wall and is tightly attached to the outer wall of the liver tissues, and a suture passing through the abdominal wall is clamped by a curved clamp or a mosquito clamp for fixation.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: liver suspends needle in midair under peritoneoscope, including blunt-headed needle 1, the outer wall welding of blunt-headed needle 1 has suture 2, and the one end fixedly connected with needle tail hose 3 that blunt-headed needle 1 was kept away from to suture 2.

In the embodiment, the blunt-headed needle 1 penetrates through the liver and the abdominal wall, when the blunt-headed needle 1 penetrates through liver tissues, blood vessels can be avoided, liver bleeding is avoided, after the blunt-headed needle 1 penetrates through the liver and the abdominal wall, the needle tail hose 3 is left in the abdominal wall and is tightly attached to the outer wall of the liver tissues, and a suture 2 penetrating through the abdominal wall is fixed by clamping a curved clamp or a mosquito clamp.

Specifically, the material of the suture 2 is a thick absorbable suture 2 or a firm silica gel suture 2.

In this embodiment, a suture 2 that does not cut liver tissue is used, such as a heavy gauge absorbable suture 2 or a strong silicone suture 2 or better.

Specifically, the suture 2 is made of a high-elasticity material.

In the embodiment, the 2-0 type straight needle is a blood vessel suture 2, which has a cutting effect on blood vessels of the liver, and when the body position is changed in the operation, the suture 2 has the cutting effect, so that the tissue bleeding is easily caused.

Specifically, the blunt-ended needle 1 is made of a shape and material similar to those of a liver needle.

In the embodiment, the original liver suspension needle adopts a 2-0 type straight needle which is actually used for intestinal anastomosis, the needle point is sharp and is easy to puncture the blood vessel of the liver to cause bleeding, and the blunt needle 1 with a blunt needle point is adopted in the utility model to avoid the bleeding injury to the liver caused by the excessively sharp needle point.
