An auxiliary device for craniofacial plastic surgery

Abstract

The invention provides an auxiliary device for a craniofacial plastic surgery. The auxiliary device for the craniofacial plastic surgery comprises a support module, a position control module, a gesture control module, a motor motion module and a surgery operation module, wherein the support module comprises a base bracket, a beam rod, a transversely H-shaped support frame and a round sleeve fixing member; the position control module is composed of a stepped rod and a drive rod and is connected to a spatial position needed by an adjustment surgery through a bolt; the gesture control module is formed by connecting two mutually orthogonal arc-shaped rods through a bearing, and composes a terminal end gesture needed by the surgery through spatial rotation; the motor motion module comprises a servo motor, a shaft coupler, a lead screw, a light bar, a bearing, a fixing frame and a connecting plate; motion along the axial direction is realized by connecting the shaft coupler, the connecting plate, the light bar and the like through the lead screw. The surgery operation module comprises a handle, a guide rail fixing block, a sliding block, a light bar, a clamp and a cutter. A strain foil sensor is adhered to the inner part of the clamp to display a force size in real time in the operation, so that the depth of bone cutting can be judged.

Description

technical field [0001] The invention relates to the field of minimally invasive plastic surgery robots, in particular to an auxiliary device for craniofacial plastic surgery. Background technique [0002] The application of computer-aided technology in the medical field is becoming more and more extensive, and it has become one of the routine directions of research and application in the field of surgery in the past 20 years. [0003] Robotic surgery has gradually become the mainstream of minimally invasive surgery. The robot system has stability and accuracy unmatched by human hands, and can be accurately positioned during the operation, reducing surgical trauma and complications, and improving the success rate of the operation. [0004] Plastic surgery mainly treats severe deformities of craniofacial bones and corresponding soft tissues caused by various congenital and acquired factors. Due to the complex anatomical structure of the cranio-maxillofacial region and dense ...

AI Technical Summary

Problems solved by technology

Experienced doctors hold a scalpel to perform cutting operations on the mandible. Due to the complex and uneven tangential force of the scalpel during the operation, the doctor needs to spend a lot of effort to maintain the stability of the scalpel; doctors are prone to fatigue during long-term operations, and it is difficult to ensure the stability of the operation Precisely
