Minimally invasive surgery instrument with tail end self-rotation function

Abstract

The invention discloses a minimally invasive surgery instrument with a tail end self-rotation function. The minimally invasive surgery instrument comprises an instrument tail end and an instrument box, wherein the instrument tail end comprises an opening and closing assembly, the opening and closing assembly comprises left opening and closing pincers which are rotatably mounted on a tail end self-rotation base through a support shaft, the tail end self-rotation base is rotatably mounted on a deflection substrate, and is connected with the rotary driving device, a deflection wheel is fixed on the deflection substrate, the front end of a tail end support is rotatably connected on the deflection substrate through a rotation shaft of the deflection wheel, the front end of a connecting long shaft is fixedly connected with the tail end support, the rear end of the connecting long shaft is fixedly connected with a rotation shaft of the instrument box, and the instrument box is internally provided with an opening and closing transmission device, a tail end self-rotation transmission device, a deflection transmission device and a rotation transmission device. The minimally invasive surgery instrument adopts the novel four-degree-of-freedom configuration form, therefore, the minimally invasive surgery instrument has the relatively high flexibility, and further, the operation difficulties of surgeries including suturing and knotting of a robot can be effectively reduced.

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...
