    • A wrist device for a prosthetic limb is provided. The device (1) comprises a base member (3) connectable to the wearer of the device, and a support member (13) connectable to the limb. The support member (13) is pivotably connected to the base member (3) such that the support member can pivot about a pivot axis (A) relative to the base member. A damping mechanism is located between the base (3) member and the support member (5). The damping mechanism comprises a pinion (47) connected to the support member (5) and rotatable about the pivot axis (A) relative to the base member (3). A rack (35) is engaged with the pinion (47) such that rotational motion of the pinion causes a linear motion of the rack, and at least one biasing member (41) extends between the base member (3) and the rack. The biasing member (41) biases the rack (35) and support member (13) into a neutral position. A prosthetic limb incorporating the wrist device is also provided.
    • 提供用于假肢的腕部装置。 装置(1)包括可连接到装置佩戴者的基座构件(3)和可连接到肢体的支撑构件(13)。 支撑构件(13)可枢转地连接到基座构件(3),使得支撑构件可相对于基座构件绕枢转轴线(A)枢转。 阻尼机构位于基部(3)构件和支撑构件(5)之间。 阻尼机构包括连接到支撑构件(5)并可相对于基座构件(3)绕枢转轴线(A)旋转的小齿轮(47)。 齿条(35)与小齿轮(47)接合,使得小齿轮的旋转运动引起齿条的线性运动,并且至少一个偏置构件(41)在基座构件(3)和齿条之间延伸。 偏置构件41将齿条35和支撑构件13偏置到中立位置。 还提供了包含手腕装置的假肢。
