Disposable tubular viscera tying lift apparatus

Abstract

The invention relates to the field of medical apparatuses, and discloses a disposable tubular viscera tying lift apparatus. The lift apparatus comprises a lock fastener, a lift ring and a protective cover. The lock fastener is a key component composed of a tying strap and a locking unit, one side of the tying strap is provided with antislip convex teeth, the other side is provided with length scales, the tying strap surrounds the tubular viscera by a circle, the movable end penetrates the locking unit prior to being tightened, and then the tubular viscera such as the esophagus, intestine and stomach can be tied, blocked, lifted and subjected to length measurement. In laparoscopic surgery, the lock fastener can be used individually, and the lift ring and the protective cover are designed for use in combination for laparotomy operation. The disposable tubular viscera tying lift apparatus is compact, elastic and flexible, and is convenient to use in narrow operation space. Compared with the past common gauze and other instruments, the disposable tubular viscera tying lift apparatus has the advantages that the no-tumor procedure during tumor distal bowel resection in laparoscopic radical rectectomy for rectal cancer is well realized; difficulty in open rectal carcinoma radical operation is lowered greatly; the disposable tubular viscera tying lift apparatus is taken out with specimens to be discarded at the end of operation.

Description

technical field [0001] The invention belongs to a medical operation instrument, and relates to a technique for binding, blocking and lifting tubular viscera in thoracic and abdominal operations. Background technique [0002] In thoracic and abdominal surgery operations, it is often necessary to bind, block and lift tubular viscera such as the esophagus, stomach, small intestine, and large intestine. No tumor, no bacteria, or no blood; the second is to lift the tubular viscera to expose the operative field, so as to facilitate various operations during the operation. In the past, most of the traditional methods were tied with gauze strips. The disadvantages are 1. The gauze strips are thick and not smooth, and the knots are not easy to tighten; 3. Especially in thoracic and laparoscopic operations, it is difficult to knot and lift gauze strips. Typical manifestations are in the radical operation of middle and low rectal cancer. [0003] In conventional laparotomy for middl...

AI Technical Summary

Problems solved by technology

In the past, most of the traditional methods were tied with gauze strips. The disadvantages are 1. The gauze strips are thick and not smooth, and the knots are not easy to tighten; The effect of blocking and lifting is not good; 3. Especially in thoracic and laparoscopic surgery, it is very difficult to tie knots and lift gauze strips

This technology will encounter the following difficulties in practical application: 1. In the case of obese patients, large tumors, low tumor locations, and narrow pelvis, it is often necessary to use large right-angle forceps to go down into the pelvic floor to clamp the distal intestine of the tumor. Very difficult; 2. Sometimes the patient’s intestinal canal is thick, and a large right-angle forceps cannot completely clamp the intestinal canal, and a small right-angle forceps must be added on the other side to make up the clamp, which increases the difficulty of the operation; 3. A good large right-angle forceps Afterwards, the access space of the pelvis is further limited, and it is even more difficult to send the cutting and closure device into the pelvis to cut and close the distal intestinal tract in the next step, and sometimes it is even impossible to do so.

[0004] However, in laparoscopic radical resection of middle and low rectal cancer, due to the difficulty of operation, there is no ideal and targeted special instrument at present. There are several serious defects in the distal intestinal tract of tumors: 1. The principle of tumor-free can not be guaranteed, which is reflected in: A. The distal intestinal tract of the tumor cannot be effectively lavaged, and the degree of tumor-free principle is greatly reduced; B. In the case of sealing the distal intestinal tract of the tumor, due to the narrow space in the pelvic cavity, the surgical operation is difficult. When the distal intestinal tract of the tumor is cut and closed with a cutting closer, part of the tumor tissue may be cut together, resulting in disastrous consequences for the remaining tumor tissue; C. There is no clear blocking mark of the distal intestinal tract of the tumor, and it is difficult to accurately grasp the distance and position of the resection margin when cutting the distal intestinal tract of the tumor, and it is difficult to guarantee whether a sufficient distance of the intestinal tract has been resected

2. It is more difficult to cut and close the distal intestinal tract of the tumor, which is reflected in: it is difficult to cut and close the distal intestinal tract under laparoscopy because there is no bundle binding and pulling the intestinal tract, and it is more difficult to close the distal intestinal tract of the tumor, and it will cost more expensive equipment Staple bin

3. Due to the inability to effectively lift the intestine, it is difficult to achieve satisfactory results in the exposure of the surgical field, which obviously affects the thoroughness of radical surgery and the progress of the operation

Compared with the current situation where most doctors give up sealing and lavaging the distal intestinal tract of the tumor, this technique has made some progress, but it also has obvious technical defects, which are reflected in: 1. The clamping of the pug forceps is not fixed and firm, It is easy to move or even loosen, and the tumor-free effect after lavage is reduced; 2. There is no lifting effect on the distal bowel of the tumor, and it is not helpful for the exposure of the surgical field; 3. There is no measurement of the length of the bowel
