Problems solved by technology

[0006] Although the above two methods can be applied to most situations, when there are obese people, especially those who are severely obese, the above two methods are difficult
The reason is that there is a large amount of fat in the abdomen of obese patients, and the depth of the umbilical incision is significantly increased, which leads to a significant increase in the travel of the inner sleeve of the multi-channel single-hole laparoscopic trocar into the abdomen.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings, and embodiments of the present invention will be given.

[0024] Such as figure 1 , 2 The introducer of the trocar for laparoscopic surgery shown is composed of an outer guide tube 12 and an inner push rod 11. The outer guide tube 12 has a trumpet-shaped upper opening, and the lower end is asymmetrically sloped. Opening, and a guide groove 15 from top to bottom is arranged on the outer wall of the outer guide tube 12 .

[0025] The upper part of the guide groove 15 is a trumpet-shaped inlet, and the notch at the lower end is symmetrical to the tip of the slope-shaped opening of the outer guide tube 12 .

[0026] The outer guiding tube 12 is a metal tube or a non-metal tube.

[0027] The slope-shaped opening at the lower part of the outer guide tube 12 is in the shape of a cutting edge.

[0028] The inner wall of the outer guide tube 12 is coated with a lubricating co...

Abstract

The invention relates to an introducer for a laparoscopic surgery puncture outfit, which consists of an outer guide pipe (12) and an inner push rod (11), wherein the outer guide pipe (12) is provided with an upper horn-shaped opening; the lower end part of the outer guide pipe (12) is an asymmetric slope-shaped opening; and the outer wall of the outer guide pipe (12) is provided with a guide slot (15) from top to bottom. According to the newly designed syringe-like introducer, the required installation action requirement can be simply and conveniently finished so as to satisfy a higher clinic requirement.

Description

technical field [0001] The invention relates to a laparoscopic operation auxiliary instrument, in particular to a laparoscopic operation puncture guide which can help the laparoscopic operation puncture device quickly enter the abdominal cavity, belonging to the medical device category. Background technique [0002] Minimally invasive surgery using laparoscopic technology is also increasingly popularized and used in China. Some hospitals at home and abroad use single-hole or multi-hole laparoscopic technology to implement transumbilical single-hole endoscopic cholecystectomy, appendectomy, and intrahepatic bile duct cystadenoma. resection etc. During the operation, these small incisions made in different parts of the abdomen with a diameter of 5-12 mm must be placed with an abdominal tunnel to facilitate the insertion of camera lenses and various special surgical instruments. The abdominal cavity captured by the camera inserted into the abdominal cavity The images of variou...
