Abstract

A minimally invasive surgery instrument having a self-rotating terminal and an instrument terminal (1) thereof. The instrument terminal (1) comprises an openable component (1-1) configured to provide a degree of freedom in opening and closing, a self-rotating terminal base (1-2), a deflection base (1-3), a deflection wheel (1-5), and a terminal support (1-6). The self-rotating terminal base (1-2) can be rotatably installed on the deflection base (1-3), and is configured to rotate with respect to the deflection base (1-3) to implement a degree of freedom (R2) in terminal self-rotation of the instrument terminal (1). A front end of the terminal support (1-6) can be rotatably connected to the deflection base (1-3) so as to implement a degree of freedom (R2) in deflection.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a surgical instrument for a minimally invasive surgical robot. Background technique [0002] Minimally invasive surgery refers to the surgical operation performed by doctors using modern medical equipment such as abdominal and thoracoscopes and supporting equipment. The derivation of minimally invasive surgical technology has made important contributions to the promotion of human development and civilization progress, and has become a global surgical field in the 21st century. main theme. Compared with open surgery, minimally invasive surgery has many advantages such as less trauma, less bleeding, and faster recovery, and has been more and more widely used in clinical operations. In recent years, with the development of science and technology and the improvement of medical needs, minimally invasive surgical robots for assisting minimally invasive surgery have emerged a...
