    • A surgical tool assembly typically includes a drive unit and a surgical tool. The drive unit includes a female drive recess for receiving the proximal end of the surgical tool. A guard is disposed in front of the drive recess and acts as a filter to limit the possible surgical tools that may be mated with the drive unit. The guard includes a non-circular filter opening with a minimum cross dimension that is larger than a minimum cross dimension of the drive recess, but smaller than the maximum cross dimension of the drive recess. Proper surgical tools include a non-round keying section that is configured to fit through the guard opening in at least one orientation. The guard is spaced sufficiently forward relative to the drive recess so that only properly keyed surgical tools may be mated with the drive recess.
    • 手术工具组件通常包括驱动单元和手术工具。 驱动单元包括用于接收外科手术工具的近端的阴性驱动凹部。 防护件设置在驱动凹槽的前面,并用作过滤器以限制可能与驱动单元配合的可能的外科手术工具。 护罩包括非圆形过滤器开口,其最小横向尺寸大于驱动凹槽的最小横向尺寸,但小于驱动凹槽的最大横向尺寸。 适当的手术工具包括非圆形键入部分,其被配置成以至少一个方向穿过防护开口。 防护件相对于驱动凹槽足够地向前间隔开,使得只有适当地键合的手术工具可以与驱动器凹槽配合。
