Auxiliary traction forceps for digestive endoscopy

The invention relates to the field of medical apparatuses and instruments, in particular to auxiliary traction forceps for a digestive endoscope, which comprise an outer tube, an inner tube and an outer tube, the handle is fixed with the near end of the outer tube; the hinge seat is fixed with the far end of the outer tube; the two clamp bodies are rotationally arranged with the hinge seat; the clamp body driving assembly can drive the two clamp bodies to open/close; the pinch-off piece is rotationally connected with one clamp body; when the two clamp bodies clamp the foreign matter, the pinch-off piece driving assembly drives the pinch-off piece to rotate, and the pinch-off piece applies shearing force to the foreign matter. When the foreign matter is made of easily-broken materials such as fishbone, the pinch-off piece cuts off the foreign matter into two parts. 本发明涉及医疗器械领域，特别涉及一种消化内镜用辅助牵引钳，外管，其的两端分别为近端、远端；手柄，其与外管的近端固定；铰接座，其与外管的远端固定；两个钳体，其与铰接座转动设置；钳体驱动组件能够驱动两个钳体张开/闭合；夹断件，其与一个钳体转动连接；其中，当两个钳体夹住异物时，夹断件驱动组件驱动夹断
