Abstract

The invention discloses a seven-degree of freedom (DOF) mechanical slave-hand device for a minimally invasive surgery, which comprises a mechanical slave-hand mechanism, a processing controller, a drive module and a sensor, wherein the processing controller is connected with the drive module which is connected with the mechanical slave-hand mechanism; and the sensor is connected with the drive module and the processing controller respectively so as to transmitting angular displacement and rotating speed information. The transmission form of the mechanical slave-hand mechanism is linear transmission; and in the linear transmission, the mechanical motion and moment between master and slave pieces are transmitted by means of a transmission line which is tightly wound on a line wheel. The seven-degree of freedom (DOF) mechanical slave-hand device for the minimally invasive surgery has the advantages of steady and continuous linear transmission, no transmission gap, small motion inertia, smooth drive and low cost, can realize complex operation of common minimally invasive surgeries, and has high flexibility.

Description

technical field [0001] The invention relates to a device in the technical field of medical devices, in particular to a seven-degree-of-freedom minimally invasive surgical mechanical slave device. Background technique [0002] Minimally Invasive Surgery MIS (Minimally Invasive Surgery, minimally invasive surgery) can reduce the patient's pain, reduce the risk of wound infection, reduce surgical scars, and patients recover quickly after surgery. At present, minimally invasive surgery has become one of the important directions of medical development in the 21st century. [0003] Surgical manipulator technology is a new interdisciplinary research field integrating medicine, biomechanics, mechanical engineering, materials science, computer science, robotics and many other disciplines. The biggest advantage of the surgical manipulator is that it can eliminate the trembling of the hands of the surgeon in different degrees and make the surgical anatomy more delicate and stable. Thi...
