Abstract

The invention relates to electric tissue holding forceps. The electric tissue holding forceps comprise a forceps holder fixer, a rotary shaft, a steel wire, a power device, a handle, a forceps holder controller and a rotation controller, wherein the forceps holder fixer is fixedly connected with the rotary shaft, the rotary shaft is connected with the power device through the steel wire, the other end of the power device is connected with the handle, the forceps holder controller is arranged outside the power device, and the power device is electrically connected with the rotation controller; the power device comprises a micro stepping motor and a transmission haft, the micro stepping motor is electrically connected with the rotation controller, and the micro stepping motor is connected with the steel wire through the transmission shaft; the forceps holder fixer is of a fine toothed structure; the micro stepping motor can be powered through an external power supply or a battery. The electric tissue holding forceps can reach the interior of the body through a treatment pipe of a double-cavity endoscope or a pipe outside the endoscope. The electric tissue holding forceps can help lift target tissue to be removed, an incisal edge can be fully exposed, operation difficulty can be reduced, and the risk of complications is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a motorized tissue holding forceps for auxiliary use in endoscopic submucosal resection. Background technique [0002] Endoscopic submucosal resection (ESD) is mainly based on various forms of electric knife. The purpose of continuous improvement of electric knife is to remove lesions faster, stop bleeding and avoid perforation. However, a clear surgical field of view is essential for performing ESD regardless of the type of electrosurgical scalpel used to remove the lesion, avoid perforation, and perform hemostasis. In actual operation, most of the complications are caused by blind operation when the visual field is not satisfactory. In addition, the unsatisfactory exposure of the surgical field of view and the fear of doctors to operate are important reasons for the prolonged operation time. [0003] At present, the technical means for exposing the surgical field of view are very limited, ...
