Abstract

The invention discloses a multi-channel puncture apparatus, which comprises a porous operating platform placed outside the abdominal cavity, a celiac channel tube connected to the porous operating platform and is suitable for insertion into the abdominal cavity. The porous operating platform comprises a bowl-shaped shell with one end closed and the other end open, a platform fixing ring which is arranged at the opening end of the bowl-shaped shell and is suitable for forming a cavity with the bowl-shaped shell, and several separate instrument channels located at the closed end of the bowl-shaped shell and being suitable for communicating with the cavity. The celiac channel tube comprises a flexible membrane channel assembly and a channel fixing ring being suitable for the flexible membranechannel assembly. The channel fixed ring is suitable for coupling with the platform fixing ring which is provided with at least a set of locking components being symmetrically arranged for simultaneously locking the channel fixing ring and the platform fixing ring.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to 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. [0003] The porous operating platform is mainly used for the insertion of the puncture cone, and it can also be used for the insertion of other instruments such as electric knife, endosc...
