通过对常规的半月板切除手术的分析，得出结论，带有侧向可控尖端的冲床将改善半月板组织的可达性。这可能会导致半月板切除术更安全、更有效。此外，目前关节镜拳头的剪刀把手在人体工程学上是不够的。符合人体工程学的手柄设计有一个杠杆，允许打开和关闭仪器尖端，并侧向转向仪器尖端。手柄的设计符合文献中的人体工程学指南。在新的手柄上增加了一个仪器尖端的模型，以与传统的手柄进行比较。实验是在膝关节模型上进行的，使用客观和主观标准。结果表明，侧向可导向冲床的概念是有希望的，因为可以在不增加损害健康组织的风险的情况下实现更快的任务时间。目前符合人体工程学的手柄设计以直观的方式融入了两个自由度，手柄握持更加舒适，易于控制。新手柄的外部存储能力可以得到改善。建议进一步开发这种手柄，并增加足够的仪器尖端和力传递。
From an analysis of the routinely performed meniscectomy procedures, it was concluded that a punch with a side-ways steerable tip would improve the reachability of meniscal tissue. This potentially leads to a safer and more efficient meniscectomy. Furthermore, the current scissors handles of arthroscopic punches are ergonomically not sufficient. An ergonomic handle is designed with one lever that enables opening and closing of the instrument tip, and side-ways steering of the instrument tip. The design of the handle complies with ergonomic guidelines that were found in the literature. A model of the instrument tip was added to the new handle for comparison with conventional handles. Experiments were performed with a knee joint model, using objective and subjective criteria. The results show that the concept of a side-ways steerable punch is promising, since faster task times are achieved without increasing the risk of damaging healthy tissue. The current design of the ergonomic handle incorporates two degrees of freedom in an intuitive way, the handle is more comfortable to hold, and easy to control. The external memory capabilities of the new handle could be improved. Further development of this handle and the addition of a sufficient instrument tip and force transmission are recommended.
