Description

Air inflation type channel device for taking out tumor specimen through anus after colorectal operation Technical Field The invention relates to the technical field of operation channels, in particular to an inflatable channel device for taking out tumor specimens through anus after colorectal operation. Background With the deep penetration of the minimally invasive concept and the rapid development of minimally invasive technology, the development of minimally invasive devices, the surgical operation is undergoing an important revolution, and the minimally invasive operation is also becoming the main role of the current surgical stage without dispute. Wounds, pain, scars, and adverse psychological implications have been considered as the necessary product of surgery. In recent years, the advent of natural transluminal specimen retrieval surgery (naturalorificespecimenextractionsurgery, NOSES) has found new directions for minimally invasive treatments. Epidemiological data in China show that 60% of colorectal cancers in China are seen in the rectum, especially in the lower rectum, 15% of patients are less than 30 years old, and BMI data of the patients in China are relatively smaller, so that the method is more technically feasible. Literature shows that colorectal cancer NOSE operation is technically feasible in the operation process, the safety is basically similar to that of the traditional laparoscopic operation, the concurrency is not obviously increased, the aesthetic effect is better, and the patient acceptability is strong; When the tumor of the patient is collected, an air inflation channel is often needed to expand the anus of the patient, but the existing device basically achieves the aim of expansion by injecting air into the air bag to expand the air bag when the patient is inflated, but when the patient is inflated, the sphincter muscle at the anus is more elastic than in the rectum, and when the patient is inflated through the air bag, the sphincter muscle can locally squeeze the air bag, the squeezing force can locally deform the air bag, so that some parts of the air bag can be excessively expanded, and other parts of the air bag are not sufficiently expanded, so that the treatment effect is affected.
