AI Technical Summary
Technical Problem
目前脑深部电刺激手术常用头皮切开方法为直切口或弧形切口，前者因切口经过颅骨钻孔(即电极进颅点)存在较大的感染风险，后者为目前常用的切口设计，但依赖术者主观目测，存在以下问题：1.切口过大导致非必要的头皮创伤、增加切口愈合不良、感染风险；2.切口过小无法显露电极进颅点或无法安装电极固定装置；3.因双侧电极进颅点较邻近导致头皮切口相互影响导致缺血、感染可能
Benefits of technology
[0021]本实用新型的有益效果包括：本实用新型提供的一种脑深部电极植入手术头皮切口辅助器，能够根据术前的立体定向方法在头皮表面标记的电极进颅的颅骨穿刺点，同时参考置入电极固定装置所需的颅骨磨除范围，对头皮弧形切口进行精准的量化设计，可有效避免头皮切口过大、过小或两侧头皮切口相互影响等不良事件，令脑深部电刺激手术的微创理念从头皮切口开始、贯穿手术全程。根据切口凹槽的设计，凹槽间隙为5mm，凹槽外弧形结构宽度为5mm，因此，切口可根据不同患者的头颅大小，在切口凹槽内圈弧形、外圈弧形内侧以及外圈弧形外侧进行选择，达到以5mm的间隔进行弧形切口的调整。
