Description

Small intestine isolation protection device

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a small intestine isolation protection device.

Background

The small intestine is the main organ in the abdominal cavity, is about 4-5 m long, occupies most of the middle and lower abdomen, and is free and has high mobility due to the long mesentery. When abdominal surgery is performed, the appearance of the surgical site and the operation visual field is often affected by the freeness and the sliding property of the small intestine, and the abdominal surgery generally comprises middle and lower abdominal, pelvic and posterior abdominal membrane operations such as colorectal surgery, gynecological surgery, urinary surgery, lymph node cleaning operation around abdominal aorta or posterior abdominal membrane operation. At present, the method of adjusting the body position of a patient or covering the small intestine with gauze or assisting the operator to pull and the like is mainly used clinically, but the effect is not ideal, the small intestine is simply surrounded by a gauze pad to be fixed, the small intestine is often overflowed from the edge of the gauze pad due to incomplete protection, the operation is affected, and a series of problems are brought: (1) in order to fully expose the operative field after entering the abdomen, the operator usually needs to spend a lot of time and energy to pull open the small intestine, thereby invisibly increasing the operation time and possibly increasing the risk of side damage to the small intestine and the mesentery thereof; (2) in pelvic cavity surgery, in order to make the small intestine slide towards the head and the feet, the head and the feet of a patient are often high, so that the lung of the patient is pressed, the respiratory function and the circulatory system function are influenced, and the difficulties of anesthesia control and stable operation process are increased; (3) under the condition that the laparoscopic surgery is difficult to expose, puncture holes may need to be increased, and an assistant keeps off the small intestine, so that the difficulty of cooperation of the assistant is increased; (4) the risk of small bowel injury in thermo-electric surgical procedures such as ultrasonic and electrotome procedures can occur if the small bowel is not fixed and frequently slides into the surgical field; (5) during operation, especially during tumor operation, the small intestine may be infected with tumor cells, which violates the principle of tumor-free technology; meanwhile, when the large intestine is operated, bacteria in the intestinal cavity can pollute the small intestine.

There is therefore a need for a device that can separate the small intestine from the surgical site to expose the surgical site for ease of operation by the surgeon, reduced procedure time and reduced complications during lower abdominal procedures, particularly laparoscopic procedures.
