AI Technical Summary

Problems solved by technology

However, as mentioned above, the heat sealing process of the retrieval bag is a special process, and factors such as the error of the heat sealing (welding) fixture, the error of the heat sealing (welding) pressure, the uneven temperature of the heat sealing (welding) and other factors are strictly controlled, which leads to differences in small batch customization. Retrieval bags of standard sizes are very expensive, so far no individual or organization has proposed or provided a feasible customized product or solution for the retrieval bag

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to an object retrieval bag and an object retrieval device. 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 retrieval bags for endoscopic surgery have been developed at home and abroad. Although the structures and usage methods of the retrieval bags are different, they can be generally divided into two categories: the first category, a single retrieval bag. US Patent No. 5,037,379 discloses a one-sided opening with a threaded retrieval bag. When in...
