[0003] However, there are some disadvantages in the use of the existing flat polyp surgery snare. In use, the first is that the polyp is not fixed and reliable, which increases the difficulty of polyp excision and reduces the efficiency of use. Second, it cannot be removed. The polyps are collected and stored. Third, the surface of the polyps cannot be cleaned, which is inconvenient for the observation of polyps. Fourth, the operation is cumbersome, inconvenient to install and disassemble, and inconvenient to use.

The invention discloses a snare for a flat polyp operation. The snare comprises a supporting mechanism, wherein a snare fixing mechanism is mounted at one side of the supporting mechanism in a threaded manner, a vacuum suction mechanism is fixedly mounted on the supporting mechanism, a storage mechanism is fixedly mounted on the supporting mechanism, the vacuum suction mechanism is in threaded connection with the storage mechanism, a storage groove is fixedly formed in the internal wall of a fixed cylinder, a limiting block is fixedly connected to one side, located at the storage groove, of the fixed cylinder, and a cutting wire is in sliding connection with the limiting block. The snare for the flat polyp operation, disclosed the invention, has the advantages that a reliable fixed structure can be provided, the difficulty of cutting is lowered, the working efficiency is increased, the surface of a flat polyp can be cleaned up, the determination of a position and size of the flat polypis facilitated, meanwhile, the cut flat polyp can be stored, the structural connection can be closer, assembly and disassembly can be more convenient, and the use is convenient.
Description
technical field [0001] This patent relates to technologies related to polyps, in particular to a technology of a snare for flat polyp surgery. Background technique [0002] In simple terms, polyps have pedunculated polyps and polyps with a wider base. Most polyps with wide bases are flat polyps, pedunculated polyps are more benign, and flat polyps are prone to malignant transformation. [0003] However, there are some disadvantages in the use of the existing flat polyp surgery snare. In use, the first is that the polyp is not fixed and reliable, which increases the difficulty of polyp excision and reduces the efficiency of use. Second, it cannot be removed. The polyps are collected and stored. Third, the surface of the polyps cannot be cleaned, which is inconvenient for the observation of polyps. Fourth, the operation is cumbersome, inconvenient to install and disassemble, and inconvenient to use. Contents of the invention [0004] The object of the present invention is ...
