    • The disclosure provides systems and methods of use pertaining to precise measurements of middle ear mechanics to aid physicians in the determination of pre-operative, intraoperative, and post-repair stiffness of the ossicular chain to assist in the diagnosis and treatment and/or repair of all types of conductive hearing loss. One embodiment provides a handheld diagnostic tool having a load cell operably coupled between a linear actuator and a rigid probe configured to rest against the ossicular chain. When the actuator displaces the load cell and the rigid probe a predetermined distance in an oscillating manner, the load cell measures a force required to displace the ossicular chain a corresponding distance. Force and displacement data is sent to a processing element, which calculates a stiffness of the ossicular chain and reports information regarding the stiffness to a display. Other embodiments are also disclosed.
    • 本公开提供了涉及精确测量中耳机械的系统和方法,以帮助医师确定听骨链的手术前,手术中和修复后僵硬,以帮助诊断和治疗和/或修复 所有类型的传导性听力损失。 一个实施例提供了一种手持式诊断工具,该手持式诊断工具具有可操作地联接在线性致动器和刚性探针之间的负载单元,该刚性探针被配置为抵靠听骨链。 当致动器以振荡方式将测压元件和刚性探针移位预定距离时,测力传感器测量将听骨链移位相应距离所需的力。 力和位移数据被发送到处理元件,处理元件计算听骨链的刚度,并将关于刚度的信息报告给显示器。 其他实施例也被公开。
