Control module for a powered surgical tool having active seals

A powered surgical tool (30) with a housing (32) that contains a power generating unit (34) such as a motor. A control module (40) is disposed in a shell that is mounted in the housing. The control module contains a plurality of polyimide energized active seals (79) for protecting internal components from the effects of sterilization. Also internal to the control module shell is a plurality of inner (77) and outer (76) stops, a plurality of O-rings, and a lid (60). Control module is sealed by inserting a fastener (55) through a lid opening and into a module shell post (57). O-rings (61,62) disposed between the lid and the shell also protect internal components from the effects of sterilization. Sensors (162, 168) secured to a mount internal the control module regulate the actuation of thepower generating unit. 一种带有包含动力产生单元(34)例如电机的外壳(32)的电动手术工具(30)。控制模块(40)被设置在安装于外壳中的壳体内。控制模块包含多个聚酰亚胺激励的主动密封件(79)用于保护内部的部件不受消毒杀菌操作的影响。控制模块壳体内部还具有多个内止挡件(77)和外止挡件(76)，多个O形圈，和盖(60)。通过将紧固件(55)插入穿过盖开口并且进入模块壳体柱(57)内，控制模块被密封。设置在盖和壳体之间的O
