Patent number: 11931270Abstract: Features for a prosthetic digit actuator. The various systems and methods allow for smaller volume actuators, which in turn allows for smaller digits and/or more space for other features of the digit. The actuator includes a motor that causes rotation of a worm gear along a fixed worm wheel. The worm gear is unibody with the output shaft. The worm gear climbs along the worm wheel to cause rotation of a digit or digit segment. The arrangement of the actuator parts allows for transmitting axial forces in first and second directions corresponding respectively to performing opening and closing rotations of the digits.Type: GrantFiled: November 13, 2020Date of Patent: March 19, 2024Assignee: Touch Bionics LimitedInventors: Rodrigo Mercader Rivera, Hugh Gill

Patent number: 11786381Abstract: Features for a powered prosthetic thumb are described. The thumb provides for rotation of a digit that mimics the natural movement possible with a sound thumb. The thumb may attach to a full or partial prosthetic hand or socket on a residual limb. The thumb may include an upper assembly, including a prosthetic thumb digit, rotatably attached to a mount about a pinch axis and a lateral axis. The digit may rotate about only the pinch axis, only the lateral axis, or both the pinch and lateral axes simultaneously. A first actuator may actuate to cause rotation of the digit about the pinch axis. A second actuator may actuate to cause rotation of the digit about the lateral axis. The first and second actuators may be actuated together at appropriate speeds to cause rotation about both the pinch and lateral axes simultaneously. A swaying chassis may be rotatably connected with the upper assembly and a lower assembly about various offset axes to provide for rotation about the lateral axis.Type: GrantFiled: March 11, 2021Date of Patent: October 17, 2023Assignee: Touch Bionics LimitedInventors: Hugh Gill, Robertus Meijer

Patent number: 11547581Abstract: Routines and methods disclosed herein can increase a power efficiency of a prosthetic hand without drastically reducing the speed at which it operates. A prosthesis can implement an acceleration profile, which can reduce an energy consumption of a motor, or an amount of electrical and/or mechanical noise produced by a motor, as the motor transitions from an idle state to a non-idle state. A prosthesis can implement a deceleration profile, which can reduce the energy consumption of the motor, or an amount of electrical and/or mechanical noise produced by a motor, as the motor transitions from a non-idle state to an idle state.Type: GrantFiled: December 19, 2019Date of Patent: January 10, 2023Assignee: Touch Bionics LimitedInventors: Steven Byrne, Neil Alexander Shaw
