Abstract
Abstract A robot for surgical operation which comprises arm means (A) mounted at its one end on a vertical support means (3) and extending in a predetermined direction. The robot comprises a drive means (B) mounted on the other end of the arm means (A) and adapted to extend substantially horizontally further in said predetermined direction. A head or trepan (C) is mounted at the extended end of and driven by said drive means (B). Light transmissive fiber or the like mounted on the trepan takes an image of the patient and a controller process the image through video data processing for driving the arm means, thereby controlling the position and tilt of the trepan with respect to the patient.

Claim 2
Dependent Claim
82 words
A robot for surgical operation which comprises (A) vertical support means; (B) arm means having a first end and a second end, said arm means being mounted at said first end on said vertical support means and extending in a predetermined direction; (C) a first drive means mounted on said second end and adapted to extend substantially horizontally further in said predetermined direction; and (D) a head mounted at the extended end of said drive means and driven by said drive means.
Claim 3
Dependent Claim
132 words
A robot for surgical operation as defined in claim l, wherein said robot further comprises a second drive means for driving the arm means to control the position of the head; said first drive means comprising a vertically movable member driven upwardly and downwardly by a drive source mounted at said second end and a drive mechanism for supporting and driving the head at its end; said drive mechanism comprising a rotary shaft for driving a cutter or the like mounted at lower end of the head, a rotary pipe mounted coaxially with and slidably rotatable around said rotary shaft for causing the head to swing left and right, and a moving pipe mounted coaxially with and slidably movable over said rotary pipe for causing the head to swing back and forth.
Claim 4
Dependent Claim
