Abstract
The utility model discloses a tumor extraction device for endoscopic surgery, which relates to the technical field of minimally invasive surgery and comprises a pair of clamping forceps, a long handle, an operating grip and a collecting bag, and the clamping forceps and the collecting bag are adjustably arranged at the front end of the long handle. Adjusting assemblies are arranged between the clamping forceps and the long handle and between the collecting bag and the long handle. A first driving part and a second driving part which are used for driving the two adjusting assemblies to move respectively are movably arranged in the long handle in a penetrating manner; the operating grip is fixedly arranged at the tail end of the long handle and fixedly connected with the first driving piece. The tumor clamp is scientific and reasonable in structural design, capable of clamping and receiving tumors at the same time, easy to operate and high in efficiency; the L-shaped driving rod and the threaded cap are matched with the first rhombic support to control opening and closing of the opening of the collecting bag, and the device can enter and be taken out of the notch conveniently. The tumor taking-out device can effectively solve the problems that an existing tumor taking-out device for the endoscopic surgery is difficult to plug in and take out from an incision, and the function is single.
