This paper presents a novel force-sensing silicone retractor that can be attached to a surgical suction pipe to improve the usability of the suction and retraction functions during neurosurgery. The retractor enables simultaneous utilization of three functions: suction, retraction, and retraction-force sensing. The retractor also reduces the number of tool changes and ensures safe retraction through visualization of the magnitude of the retraction force. The proposed force-sensing system is based on a force visualization mechanism through which the force is displayed in the form of motion of a colored pole. This enables surgeons to estimate the retraction force. When a fiberscope or camera is present, the retractor enables measurement of the retraction force with a resolution of 0.05 N. The retractor has advantages of being disposable, inexpensive, and easy to sterilize or disinfect. Finite element analysis and experiments demonstrate the validity of the proposed force-sensing system.
本文介绍了一种新型的力传感硅胶牵开器，它可以连接到手术吸引管上，以提高神经外科手术中吸引和牵开功能的可用性。该牵开器能够同时实现三种功能：吸引、牵开和牵开力传感。它还减少了器械更换的次数，并通过可视化牵开力的大小确保安全牵开。所提出的力传感系统基于一种力可视化机制，通过该机制，力以彩色杆的运动形式显示出来。这使外科医生能够估计牵开力。当存在纤维镜或摄像头时，该牵开器能够以0.05 N的分辨率测量牵开力。该牵开器具有一次性使用、价格低廉且易于消毒或灭菌的优点。有限元分析和实验证明了所提出的力传感系统的有效性。
