摘要：
An instrument (10) comprising: a light (12) having a proximal end and a distal end a handpiece (16) attached to the proximal end of the lumen (12) and including an actuator (24) a proximal articulable segment (14) having a proximal end and a distal end, the proximal end of the subject proximal articulable segment (14) pivotally to the distal end of the light (12) by a pin proximal joint (50 ) extending in a direction generally perpendicular to a longitudinal axis of the light (12) a drive cable (44) extending from the actuator (24) through the lumen (12) and into the proximal segment articulated (14) and a guiding device cable (46, 48, 52, 56 47, 54) comprising a set of proximal pulleys (247A, 247B) rotatable about pin proximal joint (50), wherein the cable (44) is wound around the set of proximal pulleys (247A, 247B), also the tool having a distal articulable portion (15) having a proximal end and a distal end, the subject proximal end of the distal pivotable segment (15) so that it can swing the distal end of the proximal articulable segment (14) by a pin distal joint (58) extending in a direction generally perpendicular to a longitudinal axis of the light (12) and wherein said pin distal joint (58) is parallel to the direction in which the pin proximal joint (50) extends, wherein the guiding device cable (46, 48, 52, 56 47, 54) further comprises a linkage assembly distal patella comprend and a set of distal pulleys (254A, 254B) rotatable about the pin distal joint (58), wherein the cable (44) is wound around the set of distal pulleys (254A, 254B), wherein the articulable proximal segment (14) has limited movement around the proximal joint pin (50) to a range of about 0 to about 90 degrees from the longitudinal axis of light (12) the distal articulable portion (15) has limited movement around the pin end joint (58) to a range of about 0 to about 90 degrees from a longitudinal axis of proximal articulable segment (50), so that the distal articulable segment ( 15) i
