Description
Technical Field
The application relates to a medical instrument, in particular to an anal canal channel component for a trans-anal minimally invasive operation, which is used for the trans-anal partial excision of rectal tumors and the trans-anal complete trans-intestinal mesentery excision operation.
Background
For benign tumors of the rectum and early rectal cancers, the traditional surgical means is to cut off the rectum tumor locally through the anus through the direct vision of the anus retractor, but the exposure of the operation field is poor, and the requirement that the tumor is close to the anus (the distance between the tumor and the anal verge is generally less than 5 cm) is the main limitation of the traditional operation method. In 1985, a german doctor, buss et al, first reported the local excision of rectal tumors using a trans-anal endoscopic microsurgical platform (TEM for short), which consists of a special proctoscope, a special surgical instrument and a scope visualization system.
The doctor Atalah et al in the United states reported first that a single-port laparoscopic tunnel was placed into the anal canal, and that after CO2 inflation, a conventional laparoscopic device was used to complete the rectal tumor partial resection, and was named TAMIS (transanal minimally invasive surgery). TAMIS surgery has made "high-grade" transanal minimally invasive surgery a reality for development in hospitals that have only conventional laparoscopic equipment. Currently commercialized single port laparoscopic channels for tami procedures are: SILS (Covidien), SSL (Ethicon), triport (Olympus), gelPOINT (Applied Medical), etc. The TAMIS platform can not only perform local excision of rectal tumors, but also has been recently reported as being used for transanal TME (taTME) surgery of advanced rectal cancer, i.e., TAMIS-TME surgery. The core component of the tami platform is a commercially available single-port laparoscopic channel.

The channel is set to be large at two ends and narrow in the middle, so that the structure can be clamped with an opening of an abdominal cavity of a human body, the channel is prevented from falling off and falling into the body cavity, the channel is made of flexible materials, and a normal channel is formed after the air bag is inflated. The current laparoscopic multi-channel devices are all similarly arranged, such a configuration is very convenient in laparoscopic surgery, but in the TAMIS operation type, since the channel needs to enter the narrow and long anorectal area, the design for preventing the channel from falling off in the operation channel assembly for the abdominal cavity is not suitable for the transanal minimally invasive surgery, and the part of the channel entering the body is formed by a plastic film, so that the anal canal is difficult to support, and thus, a channel device suitable for the transanal minimally invasive surgery is needed.
