Abstract

The invention discloses a mechanical arm with a shearing function for an abdominal surgery, and belongs to the field of medical treatment. The mechanical arm with the shearing function for the abdominal surgery comprises a control end mechanism, an executing end mechanism, a first steel wire, a second steel wire, a hose, a shearing executing mechanism, a shearing control mechanism and a third steel wire, wherein the executing end mechanism and the shearing executing mechanism are mounted at one end of the hose; the control end mechanism and the shearing control mechanism are mounted at the other end of the hose; the executing end mechanism is connected with the control end mechanism through the first steel wire and the second steel wire; and the shearing executing mechanism is connected with the shearing control mechanism through the third steel wire. The mechanical arm with the shearing function for the abdominal surgery is simple in structure and convenient and speedy to operate, andmisoperation cannot be caused easily. The steel wires are tensioned and separated by double tensioning wheels, and thus, mutual interference and winding of the steel wires are avoided effectively. Byarrangement of a fine-adjusting gear, fine action control can be carried out, and the precision of the surgery is improved. During the surgery, the shearing function can be fulfilled, and thus, the surgery efficiency is improved effectively.

Description

technical field [0001] The invention relates to a mechanical arm for abdominal surgery, in particular to a mechanical arm for abdominal surgery with a cutting function, belonging to the field of medical devices. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. At present, the structure of the mechanical arm used in laparoscopic surgery is too complicated, and it is easy to cause misoperation during operation. When cutting operation is required, other surgical instruments are needed to assist, which affects the effect and progress of the operation. Contents of the invention [0003] In order to solve the problem that the structure of the mechanical arm used in the current laparoscopic surgery is too complicated, misoperation is easy to occur during operation, and when cutting operation is required, other surgical instruments are needed to assist, wh...
