Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a novel inverted triangle single-hole laparoscope inserter. Background Art

[0002] Single-port laparoscopic surgery only requires cutting a hole in the patient's navel and inserting a surgical inserter. The surgical instruments enter the pelvic and abdominal cavities through the inserter for operation. Compared with traditional multi-port laparoscopy, single-port laparoscopic surgery does not leave obvious abdominal scars on patients. The surgery is minimally invasive and beautiful, and is well received by patients. It has been widely performed in many hospitals in recent years.

[0003] The existing inserter includes two circular support rings and an elastic membrane connected and fixed to the two support rings. A circular top cover is arranged on the elastic membrane, and a through hole is arranged on the top cover. However, since the support rings of the existing inserters are all circular, for a single-port laparoscope, the visualization lens and two operating instruments all enter from one umbilical hole. During the surgical operation, the intersection of the visualization lens and the two instruments is easy to converge on the edge of the top support ring, which will cause mutual interference between the instruments. For the surgeon, it undoubtedly increases the difficulty of the surgical operation and raises the threshold of surgical technology. Especially for complex operations, the surgeon may worry about the mutual interference of the instruments of the single-port laparoscope and choose a multi-port laparoscope instead, which limits the better promotion and application of the single-port laparoscope in clinical practice.
