Abstract
An instrument comprising an elongated control handle having a passage extending therethrough, an elongated flexible catheter body having at least one lumen and a distal end coupled to the control handle and an elongated flexible member extending through the passage and into the lumen and having a distal end portion. A tool 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 elongated flexible image-transmitting member extends through the passage of the control handle and into the lumen. A position controller 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.
Claims12
An instrument comprising:
- an elongated control handle having a passage extending therethrough;
- an elongated, flexible catheter body having at least one lumen and a distal end;
- means for coupling the catheter body to the control handle;
- an elongated flexible member extending into said lumen and having a distal end portion;
- a tool coupled to the distal end portion of the flexible member, said tool being sized to be received in said lumen and being capable of performing a medical task within a patient;
- an elongated flexible image transmitting member extending through the passage and into the lumen;
- a position controller mounted for sliding movement along the control handle;
- and
- means for drivingly coupling the position controller 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.
An instrument comprising:
- a control handle;
- an elongated, flexible catheter body having at least one lumen and a distal end;
- means for coupling the catheter body to the control handle;
- an elongated flexible member extending into said lumen and having a distal end portion;
- a tool coupled to the distal end portion of the flexible member, said tool being sized to be received in said lumen and being capable of performing a medical task within a patient;
- an elongated flexible image transmitting member extending into the lumen and having a distal end;
- a position control element mounted for movement on the control handle from a first position to a second position and then to an intermediate position between the first and second positions;
- and
- means for drivingly coupling the position control element to the flexible members such that the tool and the image transmitting member are within the lumen in the first position, the tool and the distal end of the image transmitting member are out of the lumen with the distal end of the image transmitting member being more proximal than the tool in the second position, and the tool and the distal end of the image transmitting member are out of the lumen with the distal end of the image transmitting member being positioned distally of the tool in the intermediate position.
