Single-hole multi-channel approach equipment and method for endoscopic surgery

Abstract

The invention discloses single-hole multi-channel approach equipment for endoscopic surgery, belongs to the technical field of medical equipment. The single-hole multi-channel approach equipment is characterized by comprising a cover body and a channel pipe, wherein a mounting base is fixedly connected to the top of the cover body, and a first surgical instrument pipe, a second surgical instrument pipe, a third surgical instrument pipe and a fourth surgical instrument pipe respectively communicate with the top of the mounting base; and the first surgical instrument pipe, the second surgical instrument pipe, the third surgical instrument pipe and the fourth surgical instrument pipe sequentially pass through the mounting base, and the cover body extends to the inner part of the cover body. By arranging a clamping ring, when a medical worker mounts the cover body, the cover body is placed in a connecting sleeve, so that the bottom of the clamping ring makes contact with the top of the sealing ring, and then the cover body is rotated to enable the clamping ring to rotate in the connecting sleeve. Inclined blocks which are fixedly connected to the top of the clamping ring and are annularly distributed are clamped into the bottoms of inner wall pressing blocks of the connecting sleeve, and pressure between the clamping ring and the sealing ring can be increasingly increased under the rotating action of the inclined blocks till clamping of the clamping ring is achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more specifically, to a single-hole multi-channel access device and method for laparoscopic surgery. Background technique [0002] Compared with traditional multi-hole laparoscopic surgery, single-port laparoscopic surgery has fewer incisions and is more beautiful. It is one of the development directions of minimally invasive surgery. The surgical channel is a key instrument for single-port laparoscopic surgery. Single-port laparoscopic surgery needs to place a surgical channel in the only incision. There are multiple instrument holes on the surgical channel, and multiple surgical forceps, surgical scissors and other operating instruments are placed in the surgical channel. [0003] At present, the existing single-hole multi-channel access device for laparoscopic surgery, when the device is placed at the patient's opening through a minimally invasive abdominal incision for installa...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing single-hole multi-channel access device for laparoscopic surgery, when the device is placed at the patient's opening through a minimally invasive abdominal incision for installation, the device is mostly clamped to the patient according to the elasticity of the device itself. The installation of the collar placed at the opening is dangerous and cumbersome, and there is no good sealing. When the medical staff places the surgical tools from the channel to the inner wall of the patient's abdominal cavity, there is no good fixing device for the surgical tools, so , those skilled in the art provide a single-hole multi-channel access device for endoscopic surgery to solve the problems raised in the above-mentioned background technology
