SPATIAL SERIES-PARALLEL PELVIC FRACTURE REDUCTION ROBOT - THE FIRST MEDICAL CENTER OF PLA GENERAL HOSPITAL

Title:

SPATIAL SERIES-PARALLEL PELVIC FRACTURE REDUCTION ROBOT

Document Type and Number:

WIPO Patent Application WO/2022/095289

Kind Code:

A1

Abstract:

A spatial series-parallel pelvic fracture reduction robot, relating to the field of medical robots. The spatial series-parallel pelvic fracture reduction robot comprises a base frame (I), a moving platform module (II), an arc-shaped guide rail platform module (III), a robot module (IV), and a pelvic external fixing frame (V) which are connected in sequence; the moving platform module (II) is fixedly connected on the upper part of the base frame (I) and is used for driving the arc-shaped guide rail platform module (III) to linearly move up and down and left and right; a connecting sliding block (40) of the arc-shaped guide rail platform module (III) is connected to the robot module (IV) and used for enabling the robot module (IV) to move along an arc-shaped guide rail; the robot module (IV) comprises a robot and a clamping mechanism, the robot is used for adjusting the spatial pose of the clamping mechanism, and the clamping mechanism is used for fixing bone needles; the pelvic external fixing frame (V) is used for firmly fixing the pelvis. By adopting a spatial series-parallel structure, the robot has the remarkable advantages of high rigidity, high precision, a large working space, good pose adjustment flexibility, high adaptability and the like, and can assist a doctor in accurately implementing pelvic fracture reduction surgery.
