Abstract
The present invention relates to a surgical manipulator for remotely grasping and manipulating things in response to movements of a human hand controlling the device. Movements of human fingers can be transmitted to mechanical finger-like devices through mechanical cables and linkages. In one embodiment the linkages include a mechanical movement reduction device to translate large hand movements to smaller distal movements. Various structures are provided at the proximal and distal ends for sensing and replicating the movements of a human hand.
Claims10
A mechanical hand manipulator for use in surgery, comprising:
- (a) a proximal part having a holder for receiving a human hand including a plurality of human digits;
- (b) a distal part having a plurality of independently moveable distal digits, each of said digits having at least one articulation and, wherein said distal part is of a size sufficiently small to pass through a trocar to a surgical site;
- and
- (c) a mechanical coupling portion mounted to said holder at a dorsal aspect of said human hand and connected between said proximal and distal parts to transfer movement between said proximal and distal parts,
- said mechanical coupling portion including a moveable interconnection link and a motion reducer.
A mechanical hand manipulator for use in surgery, comprising:
- (a) a proximal part having a glove for receiving a human hand including a plurality of human digits;
- (b) a distal part having a plurality of independently moveable distal digits, each of said distal digits having at least one articulation;
- (c) a coupling portion including a movable, mechanical interconnection link and a mechanical motion reducer connected between said proximal and distal parts to transfer movement of a human digit to a respective distal digit;
- and
- wherein said motion reducer is mounted on a dorsal portion of said glove.
A mechanical hand manipulator for use with a user's hand, comprising:
- a glove part, fittable on a thumb and at least one other digit of the user's hand;
- mechanical motion detectors positioned on the glove part to detect movements of the thumb and at least one other digit;
- a mechanical coupler positioned on a dorsal portion of the glove part;
- a mechanical reducer within the coupler coupled to the mechanical motion detectors;
- a shaft extending from the mechanical reducer to a distal end;
- and
- mechanical digits located at the distal end of the shaft and coupled to the mechanical reducer;
- wherein motion of the mechanical digits is controllable in response to detected movements of the thumb and at least one other digit.
