Abstract

The invention provides a positioning mechanical arm. The positioning mechanical arm comprises a tail pulley component (100), a big arm (200), a middle pulley component (300), a small arm (400), a front wheel component (500), a lifting arm (600) and a small connecting arm (700). A way of simultaneously locking a plurality of rotating joints through a band-type brake is adopted by the positioning mechanical arm, the limitation of locking single rotating joint through single band-type brake can be solved, accumulated gaps brought by the plurality of band-type brakes can be reduced, the integral quality of the mechanical arm can be reduced, and the operating precision can be improved.

Description

technical field [0001] The invention relates to the field of rotatable mechanical arms, in particular to a single brake multi-steel belt transmission positioning mechanical arm used for surgical positioning in medical equipment. Background technique [0002] As the incidence of vascular diseases such as cardiovascular and cerebrovascular diseases continues to rise, the utilization rate of minimally invasive vascular interventional surgery is also increasing. During minimally invasive vascular interventional surgery, it is necessary to feed tubes or wires into human blood vessels. The main function of the positioning robot arm is to fix the tube and wire feeding mechanism and make the tube and wire feeding mechanism reach the required spatial position. [0003] The positioning principle of existing positioning manipulators mostly uses brakes for positioning. When the brakes are energized and tightened, the corresponding rotary joints can rotate freely; when the brakes are de-...
