Endoscopic Submucosal Dissection (ESD) is a new treatment means appearing in recent years, is a technology with good clinical application prospect, enables more early digestive tract cancers to be completely resected under an endoscope at one time, and avoids the pain of an open surgery and the resection of organs. Compared with the endoscope treatment methods such as laparotomy and EMR in the past, the ESD has the advantages that 1, the wound is small, 2, a patient can receive multiple treatments at multiple positions, 3, a doctor can obtain a complete histopathology specimen for analysis, and 4, the resection rate of tumors with large areas, irregular shapes or combined ulcers and scars is higher than 96%, so that the recurrence probability is reduced.
ESD surgery is currently the primary method of treating early cancers and precancerous lesions of the digestive tract. For mucosal dissection and submucosal dissection, various incision knives, such as a hook knife, a dual knife, an end insulated scalpel (IT knife), and a hook knife, are used. The currently used incision knife is protected with or without insulation at the front end. When the range of submucosal dissection in the ESD operation process exceeds the disease boundary, the mucosa incision is difficult and the perforation is easy to carry out by using the current incision knife because the mucosa layer and the muscle layer are not protected by submucosal layer. Therefore, an ESD-specific insulating scissors is required to be designed to satisfy the requirement of mucosa peeling after the boundary of disease is exceeded.
Therefore, it is necessary to provide an insulating scissors for endoscopic mucosal dissection.
