Stapes footplate surgery is complex and delicate. This surgery is carried out in the middle ear to improve hearing. High accuracy is required to avoid critical tissues and structures near the surgical worksite. By suppressing the surgeon's tremor during the operation, accuracy can be improved. In this paper, a fully handheld active micromanipulator known as Micron is evaluated for its feasibility for this delicate operation. An ergonomic handle, a custom tip, and a brace attachment were designed for stapes footplate surgery and tested in a fenestration task through a fixed speculum. Accuracy was measured during simulated surgery in two different scenarios: Micron off (unaided) and Micron on (aided), both with image guidance. Preliminary results show that Micron significantly reduces the mean position error and the mean duration of time spent in specified dangerous zones.
镫骨足板手术复杂且精细。该手术在中耳进行以改善听力。为避免手术部位附近的关键组织和结构，需要高精度操作。通过在手术过程中抑制外科医生的震颤，可以提高精度。在本文中，对一种名为Micron的全手持式主动微操作器进行了评估，以确定其在这种精细手术中的可行性。为镫骨足板手术设计了符合人体工程学的手柄、定制尖端和支撑附件，并通过固定窥镜在开窗任务中进行了测试。在两种不同场景的模拟手术中测量了精度：Micron关闭（无辅助）和Micron开启（有辅助），两种情况均有图像引导。初步结果表明，Micron显著降低了平均位置误差以及在特定危险区域停留的平均时间。
