Abstract: A medical instrument including a shaft and an actuated structure mounted at a distal end of the shaft can employ a pair of tendons connected to the actuated structure, extending down the shaft, and respectively wound around a capstan in opposite directions. A passive preload system may maintain minimum tensions in the tendons.

Abstract: Techniques for instrument insertion control include a manipulator system. The manipulator system includes a manipulator configured to support an instrument and a control system coupled to the manipulator. The control system is configured to determine an insertion profile associated with at least one of the instrument or a cannula through which the instrument is configured to be inserted and resist or assist a manual insertion of the instrument through the cannula according to the insertion profile, wherein the resisting or assisting causes a velocity of the manual insertion to be uniform in response to a uniform force applied by the manual insertion.

Abstract: A medical instrument system includes a plurality of joints, a plurality of actuators, and a plurality of transmission systems. The transmission systems have proximal ends respectively coupled to the actuators. Each of the transmission systems have a distal end attached to an associated one of the joints to allow the transmission of a force for articulation of the medical instrument system. The system also includes a sensor coupled to measure a configuration of the medical instrument; and a control system coupled to receive configuration data, including a current configuration of a tip of the medical instrument from the sensor and a desired configuration of the tip of the medical instrument. Using the difference between the desired configuration and the current configuration of the tip of the medical instrument, the control system generates control signals for the actuators that cause the actuators to apply a set of tensions to the plurality of transmission systems.

Abstract: A surgical device comprises a tube including a proximal segment and a distal segment and a plurality of force transmission elements coupled to the tube. The force transmission elements are actuatable to alter the distal segment of the tube between a flexible state and a stiffened state. The device also comprises a plurality of routing members. Each routing member is coupled to a wall of the tube. The routing members are configured to receive and route the force transmission elements along a length of the tube while permitting the length of the tube to flex and compress. The device also comprises a decoupling structure that generates a reduced force transmitted to the proximal segment when an applied force is applied to the distal segment by the force transmission elements.

Abstract: A robotic system comprises an instrument including a proximal section and a distal section. The distal section comprises a steerable segment and a distal tip. The instrument also includes a main lumen and a pull wire. The system also comprises a sensor to detect a position of the distal tip of the instrument and a computing device that causes the system to determine, based on a sensor signal, a movement of the distal tip of the instrument in response to insertion of a probe into the main lumen and to generate a control signal based on the determined movement. The system also comprises a drive interface connected to the pull wire at the proximal section of the instrument. The drive interface adjusts a tensioning of the pull wire based on the control signal. The tensioning returns the distal tip of the instrument towards a working configuration before the movement occurred.

Abstract: A robotic system includes a master device and a slave manipulator configured to support an instrument. The instrument includes an instrument shaft having a proximal end and a distal end, and an end effector coupled to the distal end. The instrument shaft is optionally configured to be inserted into an inserted position through a port so as to provide the end effector with access to a site. A control system is operably coupled to the master device and to the slave manipulator. In response to input at the master device, the control system controls the slave manipulator to move the instrument based on modeling the end effector as being positioned along a line coincident with a longitudinal axis of the distal end of the instrument shaft. The line does not intersect the port when the instrument shaft is in the inserted position through the port. Methods relate to robotic systems.

Abstract: A robotic medical system with a flexible guide tube such as a lung catheter can record the shape of the guide tube in a target configuration. If the shape includes a bend that is sharper than a sharpest permitted bend for insertion or removal of a tool such as a biopsy needle, a control system can find any locations of sharp bends and automatically retract the guide tube to a location associated with a sharp bend. With the tip backed up to that location, the needle can be inserted into or removed from the catheter. The control system can automatically move the catheter between the target configuration and the retracted configuration of the guide tube.

Abstract: A system includes an actuator couplable to a flexible guide tube, a processor, and memory. The actuator is configured to move the flexible guide tube. The memory stores instructions that, when executed by the processor, cause the system to: identify at least one factor associated with insertion or removal of a tool configured to be inserted through or removed from the flexible guide tube; identify, in a first configuration of the flexible guide tube and based on the at least one factor, a section of the flexible guide tube having a bend that the tool cannot traverse; inform a user that the first configuration includes the section having the bend; and command the actuator to move the flexible guide tube to a second configuration. A distal portion of the flexible guide tube is disposed adjacent a target site in the first configuration. The second configuration does not include the bend.
