Abstract

The invention relates to the field of medical instruments, in particular to an opening and closing mechanism and a surgical robot. The opening and closing mechanism comprises an opening and closing actuator, an opening and closing transmission component and an execution component. The opening and closing transmission component comprises an opening and closing transmission rope and an opening and closing shaft, the opening and closing transmission rope is taken up and paid off under the driving action of the opening and closing actuator, a free end of the opening and closing transmission rope is connected to the opening and closing shaft, the opening and closing shaft is slidably assembled, and the opening and closing transmission rope pulls the opening and closing shaft to overcome the acting force of a reset part and slide forwards when the opening and closing transmission rope is taken up. When the opening and closing transmission rope is paid off, the opening and closing shaft slides reversely under the acting force of the reset part. The execution component comprises two hinged execution fingers, two ends of the opening and closing shaft are movably connected with the two execution fingers of the execution component, and the opening and closing shaft slidably pushes the two execution fingers to swing, open and close. The opening and closing mechanism solves the technical problems of more parts and complicated structure of an opening and closing mechanism in the prior art.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an opening and closing mechanism and a surgical robot. Background technique [0002] In 1987, the world's first laparoscopic cholecystectomy was successfully completed, opening a new chapter in the development of minimally invasive technology. Subsequently, a large number of advanced surgical instruments emerged, which promoted the development process of minimally invasive technology and gradually matured. Compared with traditional surgery, minimally invasive surgical treatment with less trauma, less pain, and faster recovery is widely used in clinics. Minimally invasive surgery technology has become a new direction representing medical development. [0003] In the prior art, traditional minimally invasive endoscopic surgical instruments are all slender rod structures, and surgical instruments (such as needle holders, separating forceps, surgical instruments, etc.) knife, sci...
