A robotic surgical system includes an instrument driver and an instrument assembly operatively coupled to the instrument driver such that mechanisms of the instrument driver operate or control movement, operation, or both, of components of the instrument assembly. The instrument assembly components include an elongate flexible guide instrument, an optical light source, a camera and a working tool, wherein the light source, camera, and working tool are carried in one or more lumens of the guide instrument. An operator control station is operatively coupled to the instrument driver via a remote communication link. The instrument assembly further includes an inflatable visualization balloon carried on a distal end portion of the guide instrument, the light source and camera having distal ends located within an interior of the balloon, the balloon comprising a lumen extending from the guide instrument to a distal facing wall of the balloon, such that the working instrument may extend from a respective lumen of the guide instrument through the balloon lumen to contact body tissue when the distal end of the guide instrument is positioned in an interior body region.

A method using a robotic system to perform a procedure on a patient, includes moving a control interface provided on a master input device, generating control signals corresponding, at least in part, to movement of the interface, moving one or more drive elements of an instrument driver in response to the control signal, the one or more drive elements operatively coupled to a corresponding plurality of control elements of an elongate guide instrument, the control elements secured to a distal end of the guide instrument and moveable axially relative to the guide instrument such that movement of the drive elements causes a corresponding movement of the guide instrument. The method may further comprise providing tactile feedback through the interface.
摘要:
The apparatus of one embodiment of the present invention is comprised of a flexible sheath instrument, a flexible guide instrument, and a tool. The flexible sheath instrument comprises a first instrument base removably coupleable to an instrument driver and defines a sheath instrument working lumen. The flexible guide instrument comprises a second instrument base removably coupleable to the instrument driver and is threaded through the sheath instrument working lumen. The guide instrument also defines a guide instrument working lumen. The tool is threaded through the guide instrument working lumen. For this embodiment of the apparatus, the sheath instrument and guide instrument are independently controllable relative to each other.
摘要:
A robotic medical system comprises an operator control station having a master input device, a catheter instrument, and an instrument driver in communication with the operator control station. The catheter instrument includes an elongate flexible catheter member, a flexible control element, such as, e.g., a cable, extending within the catheter member, and a proximal drivable assembly configured to axially move the control element relative to the catheter member to perform a kinematic function at a distal end of the catheter member, such as a deflection of the distal end of the catheter member. The instrument driver is configured to operate the drivable assembly to axially move the control element in response to control signals generated, at least in part, by the master input device. The drivable assembly is mounted to the instrument driver, thereby providing mechanically close relationship between the drivable assembly and the instrument driver and minimizing the errors between the actual and predicted kinematic functions otherwise introduced into the system via intervening structure between the drivable assembly and instrument driver.
