Abstract

The invention discloses a mechanical arm. The mechanical arm comprises arm racks and a swing device arranged between the arm racks; the swing device comprises a first sleeve, a second sleeve, a speed reducer and a brake; the output shaft of the speed reducer is fixed to the first sleeve; the input shaft of the speed reducer is fixed to a braking rack of the brake; the second sleeve is fixed to a brake component of the brake; the brake is released to enable the braking rack to be separated from the brake component, at the moment, the position of the mechanical arm can be adjusted through mutually rotating the first sleeve and the second sleeve, after the mechanical arm reaches a specific position, the brake is locked, the brake torque of the brake is amplified through the output shaft of the speed reducer, the output shaft of the speed reducer cannot rotate and thus the first sleeve and the second sleeve cannot rotate relatively. The position of the mechanical arm is adjusted mutually and intuitively, and large torque braking is realized through the brake and the speed reducer, as a result, the swing operation of the mechanical arm is simple and rapid, and the locking is safe and reliable. The invention further discloses a surgical robot comprising the mechanical arm.

Description

technical field [0001] The invention relates to the field of surgical machinery, in particular to a mechanical arm of a surgical robot. In addition, the present invention also relates to a surgical robot comprising the above-mentioned mechanical arm. Background technique [0002] With the development of robotic technology, surgical robots have gradually entered people's field of vision. Because surgical robots can achieve precise control of surgical instruments, they can be precisely positioned and operated, reducing patient trauma and surgical errors. They can also replace doctors for continuous long-term operations. To alleviate the shortage of medical personnel, surgical robots are becoming more and more popular with patients and doctors, and they play an increasingly important role in modern medical care. [0003] The passive arm is an important part of the surgical robot. It must be adjusted before the operation so that the surgical instruments reach the designated wor...
