摘要
An instrument comprising an elongate control handle (15) having a passage extending therethrough, an elongate flexible catheter body (17) having at least one lumen (23) and a distal end (25) coupled to the control handle and an elongate flexible member (19) extending through the passage and into the lumen and having a distal end portion (33). A tool (21) is coupled to the distal end portion of the flexible member, and the tool is capable of performing a medical task within a patient. An elongate flexible image-transmitting member (45) extends through the passage of the control handle and into the lumen. A position controller (69) is mounted for sliding movement along the control handle and is drivingly coupled to the flexible members so that the axial positions of the tool and the image-transmitting member can be adjusted with respect to the distal end of the catheter body.
