Mechanical arm of medical diagnosis and treatment surgery robot

Abstract

The invention discloses a mechanical arm of a medical diagnosis and treatment surgery robot. The mechanical arm comprises a fixing plate, a first-grade arm, a second-grade arm and a rotary disk, wherein a first electric push rod is arranged on the upper surface of the fixing plate; a first servo motor is connected to the lower part of the first electric push rod; a second servo motor is arranged on the outer wall of the first-grade arm, and is in transmission connection with the second-grade arm through a coupler; and a limiting rod is arranged on the outer wall of the second-grade arm, and isconnected with the inner wall of a limiting groove formed in the outer wall of the rotary disk. The mechanical arm of the medical diagnosis and treatment surgery robot disclosed by the invention adopts a plurality of driving equipment having independent structures, so that the rotary disk can be driven to perform multi-angle multi-height regulation operations, and the situation that the regulation range of the rotary disk is too large or too small, so that the diagnosis and treatment process of a surgery is influenced is avoided; and besides, a corresponding rolling manner of the limiting rodand the limiting groove is used for cooperation, so that the safety and the stability of the rotating course of the rotary disk are effectively guaranteed, and the running accuracy of the mechanicalarm is improved.

Description

technical field [0001] The invention relates to the technical field of medical surgical robots, in particular to a mechanical arm of a medical diagnosis and treatment surgical robot. Background technique [0002] Robotic surgery is a combination of many modern high-tech means, mainly used in the surgery of the modern medical system, so that the surgeon can operate the machine away from the operating table, completely different from the traditional concept of surgery, minimally invasive in the world The field of surgery is a well-deserved revolutionary surgical tool, and in the operation of surgical robots in medical diagnosis and treatment, it is necessary to cooperate with the mechanical arm to fix the spreader fixture to spread the incision of the patient's skin for subsequent diagnosis and treatment. Surgical operation. [0003] When the mechanical arm of the existing medical diagnosis and treatment robot adjusts the fixed fixture, it can only adjust the height and angle...

AI Technical Summary

Problems solved by technology

[0003] When the mechanical arm of the existing medical diagnosis and treatment robot adjusts the fixed fixture, it can only adjust the height and angle of a single range, which cannot meet the high precision requirements of the diagnosis and treatment operation, and is not conducive to the operation of the operation. At the same time, the number of installation structures of the fixing fixtures is also insufficient, often requiring medical personnel to frequently disassemble and replace the type of fixing fixtures, which is not conducive to the surgical operation of medical personnel
