Document Type and Number:
Japanese Patent JP2000508209
Kind Code:
A
Abstract:
A system (10) for ocular ultramicrosurgery a ring (12) for immobilising eye (14) of a patient. The incision point (P) on the eye (14) for surgical tools is marked by a marker (16) that is generated by intersecting tire beams of lasers (104 and 106). The intersection point of the laser beams is fixed in space. In order to move the patient's eye (14) so that point (P) coincides with that fixed point in space, the patient's head (52) is fixed to a head positioner (24). The head positioner is operated by a surgeon (26) through joystick (34) and computer (32) to ensure registration of point (P) and the point designated by the intersecting laser beams. All surgical tools used in the system (10) are supported, positioned and operated or worked by a tool support and positioning system (18). The system (18) comprises a stereotactic manipulator (20) and a tool translation table (22) which is supported on the manipulator (20). The manipulator (20) is used to position a surgical tool (50) on table (22) so that tip (51) of the tool (50) can be aligned with point (P). Thereafter, the manipulator (20) and/or table (22) can separately or in combination be used to pivot the tool (50) about point (A) so that the tip (51) of the tool is positioned at any desired location within the eye and subsequently worked or operated to perform ultramicrosurgery. Surgeon (26) is able to control the manipulator (20) and table (22) via computer (32) and input devices such as joysticks (34, 35) and keyboard (36). In this way, the surgeon's hands are isolated from the movement of the tool (50).
