Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a net bag set for removing polyps. Background Art

[0002] In clinical applications, endoscopic submucosal dissection (ESD) is a new technology developed based on endoscopic mucosal resection (EMR). It uses a high-frequency electric knife and special instruments under endoscopy to gradually peel off gastrointestinal lesions larger than 2 cm (including early gastrointestinal tumors) and the normal submucosal layer underneath to achieve the purpose of complete resection of the lesions.

[0003] In some ESD procedures, since the specimens to be collected are large in size, multiple instruments such as electric snares, specimen net bags, and biopsy forceps are required to cut and remove the specimens. The clinical operation is cumbersome and inefficient.

[0004] To this end, we combined clinical experience and designed a net bag set that is convenient for polyp removal based on the working principles of the electric snare, specimen net bag and biopsy forceps. The upper end of the net bag is designed as a passable electric coil with the same function as the snare, and a biopsy forceps is designed above the net bag and integrated into an outer sheath. By operating the handle at the end of the outer sheath, the multiple functions of the electric snare, specimen net bag and biopsy forceps can be realized, which optimizes the tedious steps of traditional specimen removal, eliminates the need to replace different instruments, and improves clinical surgical efficiency.
