Description

A exempt from sleeve pipe intracavity temporary assembly formula retractor suit for laparoscopic surgery

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a sleeve-free intra-cavity temporary assembly type retractor set for endoscopic surgery.

Background

In recent years, minimally invasive surgery typified by endoscopic surgery has been widely used. Up to now, the proportion of laparoscopic surgery performed annually in our country has exceeded 50% of all surgical procedures. In surgery, auxiliary instruments are often required to pull, push or press organs or tissues in order to enlarge the surgical cavity and fully expose the surgical field.

For example, when freeing the proximal stomach, the liver needs to be lifted by an assistant using graspers, which requires an additional laparoscopic cannula to be placed over the abdominal wall, compromising the minimally invasive effect of the procedure. In the endoscopic thyroid surgery, the chest lock mastoid muscle, the zonal muscle and the like are required to be pulled, so that the aim is achieved, the zonal muscle and the chest lock mastoid muscle are required to be sutured by using a suture, the suture is pulled by an assistant after being led out of the skin, and time and labor are wasted.

Patent document CN110393557a discloses that "an oral cavity access cavity mirror thyroid gland excision cavity gap tractor" can realize traction to muscle after skin puncture. Although the device does not need to add an extra incision, the tip of the device is specially shaped, so that when the subcutaneous fat of a patient is too thick, the device is very difficult to puncture, and the tip of the device is thin, so that the risk of damaging important tissues such as blood vessels, nerves and the like exists.

Therefore, the existing tissue retractor technology is difficult to meet the requirements of real minimally invasive and labor-saving, and has certain defects, and a tissue retractor which is more minimally invasive, safer and more convenient is needed in the endoscopic surgery.
