A reset robot and a control method thereof

By using a tracer to acquire pose information and calculate the reset path in the reset robot, the reset ring is driven to move to the target pose, which solves the problem of interference with fluoroscopy caused by the metal linkage platform and achieves efficient and safe fracture reduction.

AI Technical Summary

Technical Problem

Existing repositioning robots use metal linkage platforms, which cause interference with intraoperative fluoroscopic imaging, increase surgical time and operational complexity, and affect repositioning accuracy and safety.

Method used

The first and second reset rings are connected to the fractured component respectively. The pose information is obtained through a tracer, the reset path is calculated using a reset planning component, and the first reset ring is driven to move to the target pose by a reset driving component. This avoids the structural adaptation difficulties caused by directly driving the fractured component and reduces the dependence on perspective.

Benefits of technology

It improves the fluoroscopic quality of surgery, shortens the operation time, reduces patient and surgical risks, and enhances the accuracy and safety of repositioning.

Abstract

Embodiments of the present application provide a reset robot and a control method thereof. The reset robot comprises a first reset ring, a second reset ring, a first tracer, a second tracer, a reset planning component and a reset driving component. The first reset ring is configured to be connected with a first bone and drive the first bone to move; the second reset ring is configured to be connected with a second bone; the first tracer is configured to obtain first pose information of the first reset ring; the second tracer is configured to obtain second pose information of the second reset ring; the reset planning component is connected with the first tracer and the second tracer, and is configured to obtain a reset path according to the first pose information and the second pose information; the reset path guides the first bone to move relative to the second bone to a target pose; and the reset driving component is connected with the first reset ring and the second reset ring, and is configured to drive the first reset ring to move relative to the second reset ring to the target pose according to the reset path, which is conducive to reducing the difficulty of surgical operation and improving the safety of surgery.
