AI Technical Summary

Technical Problem

Existing methods of dissection during trans-blepharoplasty midface lift are prone to fixation deviation, affecting the precision and bilateral symmetry of the surgery.

Method used

By acquiring three-dimensional image data of the patient's mid-facial bone surface, individualized support configuration parameters matching the bone surface curvature are generated. The elastic support is deployed within the dissection cavity, and mechanical parameters are acquired in real time. A closed-loop control strategy is adopted to generate compensation commands and dynamically adjust the spreading force and local stiffness to maintain a constant cavity height.

Benefits of technology

It eliminates fixation deviation caused by tissue retraction, improves surgical precision and bilateral symmetry, ensures the safety of facial nerves and blood vessels, provides an objective and quantitative means of effect verification, and improves the reliability and repeatability of surgical quality.

Abstract

本发明涉及微创手术领域,公开了一种微创经睑缘中面部提升术中精准剥离系统及方法,该微创经睑缘中面部提升术中精准剥离方法,包括以下步骤:获取患者中面部骨面的三维影像数据;将弹性支撑体置入所述起始剥离腔隙并展开;基于所述力学参数采用闭环控制策略生成对抗组织回缩的补偿指令;根据所述补偿指令动态调整所述弹性支撑体的撑开力和局部刚度,将剥离腔隙高度维持在预设参考值;完成组织固定后,回收所述弹性支撑体并关闭切口。通过基于患者个体化骨面曲率生成匹配的支撑体构型参数,动态调整支撑体的撑开力和局部刚度以维持腔隙高度恒定,从而消除了剥离后至固定前因组织回缩造成的固定偏移,提升了手术的精准性与双侧对称性。
