Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings, and embodiments of the present invention will be given.

[0026] This invisible endoscopic channel for flexible abdominal minimally invasive surgery includes a porous operating platform 14 placed outside the abdominal cavity, an abdominal channel tube 15 that is connected to the porous operating platform and can be inserted into the abdominal cavity, and is characterized in that:

[0027] The multi-hole operating platform 14 is provided with a plurality of individual instrument channels 11 and at least one air inlet pipe 12 and one air outlet pipe 13 .

[0028] The abdominal passage tube 15 is a section of approximately circular flexible film passage, the upper end of which is connected to the porous operating platform 14, and the lower end is connected to a circular turning ring 19; Freely displaceable inner ferrule 16 with lifting strap 17.

[0029] In use: the porous...

Abstract

The invention relates to a multi-channel single-hole laparoscopic puncture outfit which comprises a multi-hole operating platform and a laparoscopic channel tube, wherein the multi-hole operating platform is arranged outside the abdominal cavity; and the laparoscopic channel tube is connected with the multi-hole operating platform and can be inserted into the abdominal cavity. The multi-channel single-hole laparoscopic puncture outfit is characterized in that the multi-hole operating platform is provided with a plurality of independent instrument channels having double-layer linkage air tightness, and at least one air inlet tube and one air outlet tube; the laparoscopic channel tube is an approximately circular flexible film channel, the upper end is connected with the multi-hole operating platform, and the lower end is connected with a circular overturn ring; and an inner ring with a lifting belt, capable of making a vertical free displacement, is arranged outside the laparoscopic channel tube composed of the flexible film. The puncture outfit has the air tightness function, and can ensure that the instrument maintains a pneumoperitoneum pressure when being moved in vivo; and the simple air inlet tube mechanism ensures the maintained pneumoperitoneum pressure and facilitates the quick removal of fume generated when human tissues are subjected to electric knife cauterization. The entire puncture outfit is so flexible that surgeons can freely operate the instrument, thereby shortening the surgery time.

Description

technical field [0001] The invention relates to an auxiliary instrument for abdominal cavity operation, in particular to a multi-channel single-hole laparoscopic operation puncture device. Background technique [0002] With the development of medical technology, minimally invasive surgery using laparoscopic technology has been increasingly popularized and used in China. In laparoscopic surgery, 2-4 hole operations are often used, one of which is opened on the navel (or other parts of the abdomen) of the human body to avoid leaving long scars on the patient's abdominal cavity. After recovery, only in the abdominal cavity There are 1-3 linear scars of 0.5-1 cm left on the site, which can be said to be a small wound and less painful surgery, so some people call it "keyhole" surgery. The development of laparoscopic surgery reduces the pain of surgery for patients, shortens the recovery period of patients, and relatively reduces the expenditure of patients. It is a surgical item...
