Abstract

The invention provides a mucous membrane traction device and an endoscopic system, and relates to the field of medical devices. The mucous membrane traction device comprises a tube body, a first clampand a traction piece, the first clamp is arranged at a far end of the tube body, the traction piece is provided with a first acting part and a second acting part, the first acting part acts on the far end of the tube body, the second acting part is used for acting on a far end of an endoscope, under a condition that the traction piece is pulled, the far end of the tube body and the far end of theendoscope are close to each other and keep fixed, and under a condition that the traction piece is loosened, the far end of the tube body and the far end of the endoscope can move independently. Theendoscopic system comprises the mucous membrane traction device. The mucous membrane traction device and the endoscopic system can keep a traction force of the traction piece on the premise that the first clamp is not added, the first clamp cannot be retained in human body after an operation is completed, and risks of safety accidents are reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a mucosa traction device and an endoscope system. Background technique [0002] Endoscopic submucosal dissection (ESD) is a relatively mature minimally invasive surgery for early gastrointestinal cancer. Due to its advantages of small trauma, no change in the structure of the digestive tract, avoiding surgical risks, and reducing the decline in postoperative quality of life, it has become more and more popular. more popular. However, for some lesions that are difficult to treat with ESD, it is necessary to cooperate with endoscope-assisted traction technology to obtain a good field of view for surgical operation. [0003] At present, endoscope-assisted traction technology includes metal clip wire combined traction technology, metal clip elastic ring combined traction technology, metal clip pull ring traction technology, S-O metal clip traction technology, magnetic anchor tract...
