Guiding and positioning robot

Abstract

The invention provides a guiding and positioning robot. The guiding and positioning robot comprises a bracket, an operation arm and at least two groups of moving units, wherein the bracket comprises at least two circular chutes which are coaxially arranged; each circular chute is in one-to-one correspondence to the corresponding group of the moving units; the bracket comprises a passing hole located in the middle parts of the circular chutes; each group of moving units comprises a rotating seat which is suitable for performing rotation along the corresponding circular chute, a guide rail arranged on the rotating seat, a sliding block suitable for moving along the corresponding guiding rail, a ball hinge mounted at each sliding block and a driving device; each guide rail is perpendicular tothe axis center of the corresponding circular chute; a mounting hole is formed in the center of each ball hinge; each driving device is used for adjusting the rotating position of the corresponding rotating seat relative to the corresponding circular chute and / or the moving position of the corresponding sliding block relative to the corresponding guide rail; the ball hinges of the groups of themoving units are separated from each other in the axial direction; and the operation arm penetrates through the passing hole of the bracket, and penetrates the mouthing holes of the ball hinges of theat least two groups of the moving units.

Description

technical field [0001] The invention relates to the field of medical devices, and more specifically, to a guiding and positioning robot. Background technique [0002] Cancer is a major threat to human health today. A commonly used diagnostic measure, biopsy is the gold standard for diagnosing cancer. Biopsy procedures are usually performed manually by a surgeon using a biopsy needle or a biopsy gun. However, the lesion is usually located in the subcutaneous tissue or organ, and it is difficult for the surgeon to accurately locate the target location, which often leads to false negative results and affects the timely control and treatment of the disease. [0003] Medical robots are more and more widely used in various operations because of their accuracy and stability. With the development of technology, medical robots will gradually become the basic configuration of hospitals. Biopsy robots with guided positioning can improve the accuracy and effectiveness of cancer diagn...

AI Technical Summary

Problems solved by technology

Biopsy robots with guided positioning can improve the accuracy and effectiveness of cancer diagnosis. However, at present, many biopsy robots are transformed from traditional serial robotic arms.

In addition, due to the huge volume and the existence of various metal parts, it cannot be MRI compatible.
