Abstract

The invention discloses a medical fetching device comprising a loose state. The medical fetching device comprises a fetching bag, wherein the fetching bag comprises a bag opening and a bag body, and the bag opening can be opened and closed, and the bag body is formed by extending from the bag opening; the bag opening comprises a surrounding tunnel; the fetching bag further comprises a binding wire; the far end of the binding wire comprises a sliding joint; the far end of the binding wire penetrates through the tunnel, and the near end of the binding wire penetrates through the sliding joint, and a binding wire ring with the size roughly the same as that of the bag opening is formed; the fetching device further comprises a flexible hollow pipe, and the hollow pipe comprises a far-end pipe part, a middle-end pipe part, a near-end pipe part and an axis; and a specimen bag is curled or folded to be accommodated in the hollow pipe.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a medical fetcher including a loose state. Background technique [0002] In minimally invasive surgery (especially rigid endoscopic surgery), it is usually necessary to remove internal tissues or diseased organs through a small incision in the patient's skin or through a puncture catheter. How to safely and conveniently remove intracavitary tissue or diseased organs has always been a difficult problem in minimally invasive surgery. Since the first clinical application of rigid endoscopic surgery, a variety of special specimen bags for endoscopic surgery have been developed at home and abroad. Although the structures and usage methods of the specimen bags are different, they can be generally divided into two categories: the first category, a single specimen bag. US Patent No. 5,037,379 discloses a lined specimen bag with a unilateral opening. When in use, the specimen ...
