The invention discloses a medical object picker comprising a plurality of belt rails, comprising a specimen bag, the specimen bag comprising an openable and foldable bag mouth and a bag body extending from the bag mouth, the bag body comprising a first a pocket surface and a second pocket surface; the pocket opening includes a surrounding pocket opening track, characterized in that: the outer surface of the first pocket surface and the second pocket surface of the bag body includes a belt track; the waistband track is formed by an additional The thin film is welded on the first bag surface and the second bag surface; the extractor also includes a waist belt running through the waist belt track, and also includes a spreader mechanism, a catheter assembly and a handle assembly; the spreader mechanism includes elastic a body and a fixing seat for fixing it; the elastic body includes an elastic ring, the elastic ring is built in the pocket track, and the fixing seat is installed at the distal end of the handle assembly; the specimen bag is wound around the outer circumference of the elastic ring, The entire elastic ring is forced to deform, thereby receiving the specimen bag, spreader mechanism and handle assembly in the catheter assembly.
Description
technical field [0001] The invention relates to minimally invasive surgical instruments, in particular to a medical object extractor comprising multiple belt tracks. Background technique [0002] In minimally invasive surgery (especially rigid endoscopic surgery), it is usually necessary to take out internal tissue or diseased organs through a small incision in the patient's skin or through a puncture catheter. How to safely and conveniently remove intraluminal tissues or diseased organs has always been a difficult problem for 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 structure and usage of the specimen bags are different, they can generally be divided into two categories: the first type, a single specimen bag. The second category includes extraction instruments containing specimen bags, catheters and distraction...
