具有可机械操作的手指或脚趾构件的假肢
摘要：
一种用于提供至少一个可机械操作的手指或脚趾构件的假肢(1)。该假肢(1)具有至少一个手指或脚趾构件(3)，该手指或脚趾构件(3)大致正切于假肢的支撑构件上的固定式蜗轮装置(5)延伸，且被安装用于绕蜗轮装置转轴(8)旋转。手指或脚趾构件具有可操作的驱动电机(7)以驱动蜗杆装置(13)。蜗杆装置(13)与蜗轮装置(5)啮合以便在假肢的使用中，当操作驱动电机时，手指或脚趾构件(3)在蜗轮装置(5)周围移动，其中蜗杆装置(13)设置在手指或脚趾构件(3)外。
摘要（英）：

A prosthesis (1) for providing at least one mechanically operable digit member. The prosthesis (1) has at least one digit member (3) extending generally tangentially with respect to a fixed worm gear wheel means (5) on a support member of the prosthesis and mounted for rotation about the worm gear wheel means axis (8). The digit member has a drive motor (7) operable to drive a worm means (13). The worm means (13) is in engagement with the worm gear wheel means (5) so that when the drive motor is operated, in use of the prosthesis, the digit member (3) moves around the worm gear wheel means (5), in which the worm means (13) is disposed out of the digit member (3).
