Modular joints for a collaborative positioning arm of a minimally invasive surgical robot

Abstract

A modular joint for a collaborative positioning arm of a minimally invasive surgical robot, comprising: a housing, a drive mechanism fixedly disposed in the housing, and an output mechanism rotatably disposed in the housing, wherein: the drive mechanism is connected to the output mechanism, and the drive The mechanism is connected with the output mechanism or frame of other modular joints, and the output mechanism is connected with the driving mechanism or mechanical claws of other modular joints. The invention adopts the interval layered structure of the rotating part and the fixed part in the transmission shaft; the active work of the cooperative positioning arm is realized through the operation of the motor, which has a large output torque and a reasonable movement speed, high control precision, small size and weight It is light, and the parts are easy to install, which ensures the personal safety of medical staff.

Description

technical field [0001] The invention relates to a technology in the field of medical robots, in particular to a modular joint for a cooperative positioning arm of a minimally invasive surgical robot. Background technique [0002] Minimally invasive surgical robots need to work collaboratively with medical staff during use, which puts high demands on their safety. In the existing product technology, in order to ensure safety, the robotic arm used for preoperative positioning in minimally invasive surgery is usually passive, and there are few active positioning robotic arms, which cannot collect control and safety detection data in real time. The output torque and movement speed of the mechanical arm cannot be well controlled, which is likely to pose a threat to the personal safety of medical staff. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a modular joint for a cooperative positioning arm ...
