Description

Laparoscopic script taking-out device

Technical Field

The invention belongs to the technical field of medical supplies, and particularly relates to a laparoscopic specimen taking-out device.

Background

With the continuous progress of human medical technology, endoscopic minimally invasive surgery, represented by laparoscopic surgery, is increasingly becoming the trend and mainstream of surgical development. At present, the amount of laparoscopic surgery in China is gradually increased year by year, not only more and more hospitals have the technology and conditions for carrying out laparoscopic surgery, but also along with the continuous proficiency and perfection of the operation technology of doctors, a plurality of open operations in the past are replaced by intracavity surgery. Compared with the traditional operation, the laparoscopic operation has the characteristics of small wound to a patient, light pain, quick healing after the operation and the like. However, in laparoscopic surgery, how to safely and thoroughly remove surgical excision and residues is always a key point and a difficult point, which is not only directly related to success or failure of the whole laparoscopic surgery, but also related to postoperative rehabilitation of patients. For a long time, the domestic laparoscopic surgery does not have a medical tool specially for taking out the resection objects, and a hospital for carrying out the laparoscopic surgery can only use homemade gloves or homemade plastic bags to finish the critical step after simple processing and disinfection. Such self-made gloves or self-made plastic bags are troublesome to manufacture, and it is difficult to ensure that surgical excision and residues are completely and thoroughly taken out, so that a greater risk of infection exists, and a great deal of inconvenience and hidden danger are brought to surgical operators.
