Partial hand prosthesis
First Claim
1. A partial hand prosthetic system compromising:
- a liner for surrounding the remnant portion of a hand;
a harness adapted to fit about said remnant portion of said amputated hand and having an opening for accommodating said liner;
at least one moveably mounted opposition member supported by said harness;
at least one sensor positioned about said harness and arranged to detect a force exerted by an area of said remnant portion;
wherein a force exerted by said remnant portion of said amputated hand is detected by said sensor and causes said opposition member to move.

Abstract
A prosthetic device (12) and liner (14) form a prosthetic system (10) that can substantially mimic the cosmetic and functional qualities of a human hand. A harness (22) is adapted to fit about a remnant portion (16) of a hand (18). The harness has an opening (26) for accommodating the liner (14). A moveably mounted opposition member (24) is supported by the harness (22) and sensors (60, 62) positioned about the harness (22) detect a force exerted by an area (40) in proximity to the hypothenar eminence of remnant portion. Once a force is detected by either sensor (60, 62) a signal is communicated to a controller (70) which activates a motor (100) causing motion of the opposition member (24).

10. A partial hand prosthesis comprising:
-
a harness having an opening with a shape accommodating the remnant portion of a hand;
at least one moveably mounted opposition member supported by said harness;
an electro-mechanical subsystem configured to cause said opposition member to move in response to a movement of an area substantially proximate the hypothenar eminence of said remnant portion of said amputated hand. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. In connection with a partial hand prosthetic device having at least one finger member with one end rotatably mounted to a shaft member, a prosthetic drive control system comprising:
-
a motor having an input for initiating a torque drive and an output;
a drive subsystem coupling said motor to said shaft member, said drive subsystem operably connected to said output of said motor for coupling a force to said shaft member that controls the motion of said prosthetic finger member; and
sensor for causing the actuation of said motor, said sensor adapted to detect the movement of an area substantially proximate the hypothenar eminence of a remnant portion of a hand. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

30. In connection with a partial hand prosthesis having an opposition member moveably attached to prosthetic harness, the prosthetic harness providing a platform for a plurality of electro-mechanical components, a method of causing said opposition member to move comprising the steps of:
-
a sensor detecting the movement in a first direction of an area substantially proximate the hypothenar eminence of a remnant portion of a hand;
the sensor communicating a signal to a controller indicating movement has been detected;
the controller activating a motor operably coupled to said opposition member through a drive subsystem;
the drive subsystem transferring a force from said motor to said opposition member thereby causing said opposition member to move in a first direction towards a thumb of said amputated hand. - View Dependent Claims (31, 32, 33)
