Air-filled channel apparatus for removing tumor specimens from anus after colorectal surgery

Abstract

The invention discloses an air-filled channel apparatus for removing tumor specimens from anus after colorectal surgery. The air-filled channel apparatus comprises a plurality of channel tubes, air tubes, at least two support frames and at least one diaphragm, outer sides of the adjacent channel tubes in sequence are attached and enclosed, and each channel tube is of a cylinder with two ends enclosed and comprises a head, a middle part and a tail part; the wall surface of each channel tube is of an elastic thin wall, and the air tube is located at the tail part of the channel tube and is communicated with the cavity of the channel tube; a ventilation tube is arranged between two neighboring channel tubes and is connected with the neighboring cavities, the diaphragms are arranged in the cavities of the channel tubes, the diaphragms are made of elastic materials, and edges of the diaphragms are tightly connected with the wall surfaces of the channel tubes. By the arrangement, the rumor removed from the anus is assured not to touch the inner wall of the abdominal cavity and tissue in the same, shedding of tumor cells and occurrence of infection can be avoided, wall surface of the bowel can be supported when the air-filled channel apparatus is put into the bowel, and difficulty in operation is greatly lowered.

Description

technical field [0001] The invention relates to a medical device for laparoscopic surgery, 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 y...

Problems solved by technology

However, the above-mentioned operation process is difficult, takes a long time, and has many disadvantages, resulting in a relatively low efficiency of the operation; for example, when some simple air-filled channel devices inject gas into the cavity, the gas supports the elastic thin wall , the elastic thin wall stretches to form a regular channel, but the supported channel will inevitably collapse and sag, so the rectum cannot be completely stretched, and the removal of the tumor is complicated, which increases the difficulty of the operation for medical staff
