Abstract

The invention discloses a connecting structure for a multi-channel puncturing device, comprising a platform fixing ring, a channel fixing ring adapted to be sleeved with the platform fixing ring, andat least a group of symmetrically arranged locking assemblies connected with the platform fixing ring. The platform fixing ring comprises a platform base body, a platform perforation arranged in the platform base body, and a platform wing part connected with the platform base body and arranged around the outer periphery of the platform perforation. The channel fixing ring comprises a ring-shaped channel base, a channel perforation coaxial with the platform perforation arranged in the channel base, and a channel wing part connected with the channel base and arranged around the outer periphery of the channel perforation. And the latch assembly includes an articulated shaft and a locking member connected to the platform retaining ring through the articulated shaft.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a connection structure for a multi-channel trocar. Background technique [0002] Minimally invasive laparoscopic surgery for cholecystectomy, appendectomy, intrahepatic bile duct cystadenoma resection, etc., often uses a multi-channel single-hole laparoscopic trocar. The multi-channel single-hole laparoscopic trocar includes a multi-hole operating platform and an abdominal channel tube connected to the multi-hole operating platform. sex. Some multi-channel single-hole laparoscopic trocars in the prior art are used to realize the connection structure between the multi-hole operating platform and the abdominal channel tube, or there are problems of cumbersome operation or lack of airtightness after connection. Contents of the invention [0003] The purpose of the present invention is to provide a connection structure for a multi-channel trocar to solve the technical pro...
