Embodiment Construction
[0022] The specific structure of the novel single-hole laparoscopic sheath design of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] The component assembly includes a flexible sheath (1), a catheter (2), wherein the flexible sheath (1) is composed of a flexible channel (1-1), an air bag (1-2) in the sheath, and an external fixation ring (1- 3), corrugated elastic retractor tube (1-4), internal fixation ring (1-5), corrugated elastic device (1-6), catheter (2) consists of double air-closing valve (2-1), instrument guide tube ( 2-2) Composition. The single-hole laparoscopic sheath is used to retract the surgical incision on the body surface, provide the operating channel for surgical instruments, and ensure the airtightness of the operating channel while retracting the incision; when in use, put the internal fixation ring (1-3) through the small incision on the abdominal wall In the abdomen, the extracorporeal fixa...
