Description
Technical Field
The invention belongs to the technical field of medical endoscopic surgery auxiliary instruments, and particularly relates to a laparoscopic object taking bag, aiming at a resected tissue taking instrument used in a laparoscopic surgery process.
Background
Compared with the traditional operation, the laparoscopic surgery is popular with patients because the postoperative scar is small and meets the aesthetic requirement. Currently, most common surgical procedures, laparoscopic procedures, are accomplished. Such as appendectomy, gastric, duodenal ulcer perforation repair, hernia repair, colectomy, splenectomy, adrenalectomy, ovarian cyst removal, ectopic pregnancy, hysterectomy, hysteromyoma removal, etc., which can be employed in almost all surgical procedures with the increasing sophistication of laparoscopic techniques and the increasing level of laparoscopic surgeon procedures.
At present, large tissues cut off under a laparoscope, such as hysterectomy, hysteromyoma excision and excision of other neoplastic tissues, are usually taken out after being cut up or smashed, the time required for the cutting up process of the large tissues is long, a doctor needs to operate for many times to finish the cutting up process of the large tissues, liquid leakage is easy to generate in the operation process, the large tissues are not easy to clear, and the missing tissues and cells can cause metastasis and diffusion of tumor tissues in the in-vivo cutting up or smashing process of inaccurate malignant tumor tissues before operation, so that larger diseases are caused. There is therefore a need for an effective solution to the above-mentioned technical problems.
The invention relates to a laparoscopic fetching bag, which aims at solving the problem that the prior art does not have an instrument for effectively and reasonably cutting and fetching massive tissues during laparoscopic surgery.
Disclosure of Invention
The invention provides a laparoscopic fetching bag, which aims to solve the technical problems that a large piece of tissue cannot be effectively cut during laparoscopic surgery, the time consumption is long when the cut tissue is taken out and the like in the prior art.
