Abstract
The invention relates to a pair of bipolar coagulation scissors. The pair of bipolar coagulation scissors comprises a handle, a hose, a scissor body, a linkage assembly and a fixing device. The fixing device is fixedly arranged at one end of the hose, a rectangular opening is formed in the fixing device, and the scissor body is inserted into the rectangular opening; the handle is arranged at the end, away from the fixing device, of the hose, the handle is connected with the scissor body through the linkage assembly, the handle comprises a pressing block, a sliding rod and a driving block, the pressing block is connected with the driving block through the sliding block, and the driving block is connected with the linkage assembly; the linkage assembly comprises a lead screw, an auxiliary device and a sliding block, the lead screw and the auxiliary device are arranged inside the hose in a sleeving mode, the driving block is connected to the end, away from the fixing device, of the auxiliary device, the lead screw is arranged at the end, close to the fixing device, of the auxiliary device, the driving block is connected to the end, away from the fixing device, of the lead screw, two connecting portions are arranged at the end, close to the fixing device, of the lead screw, each connecting portion is connected with a blade, and the sliding block is arranged between the connecting portions in a sleeved mode. According to the bipolar coagulation scissors, the occupied space is small, and rotation caused when the pair of bipolar coagulation scissors works is avoided.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bipolar electric coagulation shear. Background technique [0002] At present, with the improvement of endoscopic treatment methods, more and more endoscopic minimally invasive treatment methods and methods have been carried out, especially endoscopic polyp, tumor resection, endoscopic retrograde cholangiopancreatography (ERCP), The development of endoscopic sphincterotomy (EST), endoscopic mucosal resection (EMR), and endoscopic mucosal dissection (ESD) has enabled some patients to relieve their pain without surgery. However, these operations require incision treatment. At present, snares, thermal biopsy forceps, needle incision knives, etc. are generally used for operations. However, the existing incision tools under the microscope are not safe enough, and the operation is also inconvenient. The range is limited. For some polyps or tumors that are difficult to be...
