Surgical manipulator

Claim 2

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.

Claim 3

A mechanical hand manipulator according to claim 1 wherein said moveable interconnection link comprises a cable.

Claim 4

A mechanical hand manipulator according to claim 1 wherein said independently moveable distal digits are coated with an elastomeric coating.

Claim 5

A mechanical hand manipulator according to claim 1 further comprising a mechanical protection and retraction device for releasably enclosing said plurality of independently moveable distal digits inside said mechanical protection and retraction device, said device including: (a) a protection tube having an inside diameter and an outside diameter, said inside diameter of said protection tube being of sufficient size to enclose said plurality of independently moveable distal digits and said outside diameter being of sufficient size to permit said protection tube to slide within a trocar shell, and (b) a release stopping pin to releasably hold said plurality of independently moveable distal digits inside said protection tube, said release stopping pin having a first position and a second position, wherein said plurality of independently movable distal digits is inside said protection tube when said release stopping pin is in said first position and at least one of said plurality of independently movable distal digits is outside said protection tube when said release stopping pin is in said second position.

Claim 6

A mechanical hand manipulator according to claim 1 wherein said holder is a glove for receiving at least a portion of a human hand.

Claim 7

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.

Claim 8

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.

Claim 9

A mechanical hand manipulator according to claim 6 wherein said moveable interconnection link is a cable.

Claim 10

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.

Claim 11

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.

Claim 12

A mechanical hand manipulator according to claim 8, further comprising Bowden cables forming couplings between the motion detectors and the mechanical reducer, and Bowden cables forming couplings between the mechanical reducer and the mechanical digits.

Claim 13

A mechanical hand manipulator according to claim 8, further comprising a mechanical protector at the distal end of the shaft, the protector including a tube having an inside diameter and an outside diameter, the inside diameter of the tube sufficiently large to enclose the mechanical digits, and a release stopping pin to releasably hold the mechanical digits inside the tube, the release stopping pin having a first position and a second position, the mechanical digits being inside the tube when the release stopping pin is in the first position and at least one the digits being outside the tube when the release stopping pin is in the second position.
