An inflation type passage device used for taking out a tumor sample per anum after colorectal surgery

Abstract

The invention provides an inflation type passage device used for taking out a tumor sample per anum after colorectal surgery. The inflation type passage device comprises a passage wall, an inflation pipe, supporting racks and a membrane. The passage wall is in the same of a cylinder with two open ends and comprises a head portion, a middle portion and a tail portion; the passage wall is divided into an inner layer and an outer layer, wherein a cavity is formed between the two layers of elastic thin walls; the inflation pipe is located on the outer surface of the tail portions of the passage wall and communicates with the cavity; the head portion and the tail portion of the passage wall are provided with solid annular supporting racks; the inside of the middle portion of the passage wall isalso provided with the membrane made of elastic materials; the edge of the membrane is hermetically connected with the inner wall of the passage wall. When not inflated, the device is in the shape ofa long strip, so that the device can be placed into a body of a patient without causing much pain to the patient; the supporting racks enable the passage wall to maintain the cylinder shape after inflation, so that operation space is provided to allow operating forceps to clamp a tumor and place the tumor into the passage wall, so that the difficulty of operation is reduced and the success rate is reduced; tumors are completely located in the passage wall, so that the tumors are prevented from spreading after being taken out; the membrane can effectively prevent decompression of an abdominalcavity to guarantee normal progress of surgery.

Description

technical field [0001] The invention relates to laparoscopic surgery medical equipment, in particular to an air-filled channel device for taking out tumor specimens through the anus after colorectal surgery. Background technique [0002] With the popularity of minimally invasive concepts, the rapid development of minimally invasive technology, and the development of minimally invasive equipment, surgery is undergoing an important revolution, and minimally invasive surgery has undoubtedly become the main role in the current surgical stage. Trauma, pain, scars, and negative psychological implications have long been considered inevitable outcomes of surgery. In recent years, the emergence of natural orifice specimen extraction surgery (NOSES) has found a new direction for minimally invasive treatment. Epidemiological data in my country show that 60% of the incidence of colorectal cancer in China is in the rectum, especially in the lower rectum, and 15% of the patients are youn...
