A system for extracting information of objects from video captured during a medical procedure that includes an image repository configured to store image data representing views within a luminal network, a log repository configured to store commands and/or states associated with an object within the luminal network, and control circuitry. The control circuitry can be configured to generate change data representing changes of visual states of the object over a time period, access the log repository to determine logs including at least one command or at least one state associated with the object over the time period, and generate contextual information associated with the object based at least in part on (i) the change data and (ii) the at least one command or the at least one state associated with the object.

A system for surgical planning and assessment of spinal pathology or spinal deformity correction in a subject, the system comprises a control unit configured to align one or more vertebral bodies of a biomechanical model to one or more vertebral bodies of the radiograph. The control unit is configured to receive one or more spinal correction inputs. The control unit is configured to, based on the received one or more spinal correction inputs, simulate the biomechanical model in a predetermined posture. The control unit is configured to provide for display one or more characteristics of the simulated biomechanical model.

A surgical tool includes an elongate shaft, an end effector arranged at a distal end of the shaft and including opposing jaws, and an articulable wrist interposing the end effector and the shaft and comprising a plurality of articulation links arranged in series along a longitudinal length of the wrist. A closure redirect mechanism includes first and second rigid links arranged proximal to the wrist, first and second transfer mechanisms pivotably mounted to the first and second rigid links, respectively, first and second transfer links interposing the end effector and the wrist, and first and second tension members extending distally from the first and second transfer mechanisms, respectively, and being secured to the first and second transfer links, respectively. Moving the first rigid link relative to the second rigid link, and vice versa, causes the first and second transfer links to correspondingly move and thereby open or close the jaws.

A drive system for achieving supra-aortic access and neurovascular treatment site access includes a guidewire hub configured to adjust an axial position and a rotational position of a guidewire, a procedure catheter hub configured to adjust an axial position and a rotational position of a procedure catheter, a guide catheter hub configured to adjust an axial position of a guide catheter, and an access catheter hub configured to adjust an axial position and a rotational position of an access catheter, the access catheter further configured to laterally deflect a distal deflection zone of the access catheter.

A system and method include operation of a device coupled to a base to hold a catheter to the base, the catheter defining a lumen in which a portion of an elongated medical device is disposed, and a portion of the catheter being disposed in a hemostasis valve, movement of the base relative to the hemostasis valve along a first path while the catheter is held to the base such that the catheter moves relative to the hemostasis valve, and operation of a mechanism coupled to the base to maintain a position of the elongated medical device within the lumen relative to the hemostasis valve while the base and the mechanism are moved along the first path and the catheter is held to the base.

A steerable catheter comprises a plurality of control elements, a proximal section, a transition section, and a distal section. The proximal section includes a plurality of conduits to transfer actuation forces applied to one or more of the control elements from a distal end to a proximal end of the proximal section. Each control element extends within a respective conduit. The transition section includes a stopper to prevent the conduits from moving axially along the steerable catheter. The stopper comprises grooves for receiving the control elements. The distal section includes an axial support structure to support the distal section against axial loads generated by the control elements. The axial support structure extends from the transition section to a distal end of the distal section. The stopper prevents the conduits from extending into the distal section and allows the control elements to extend into the distal section.

A multi-instrument cooperative flexible ureteroscope surgical robot is provided, which relates to the field of medical surgical robots. The system specifically includes a flexible ureteroscope driving device, a ureteral guide sheath driving device, a flexible ureteroscope rapid assembly device, a sheath rapid assembly device, a guide wire feeding device, a control box and other components. Firstly, the ureteral guide sheath driving device accurately positions a ureteral guide sheath into the urethra and ureter of the patient. Then, the flexible ureteroscope driving device drives a disposable flexible ureteroscope to enter into the body through the positioned ureteral guide sheath, and the guide wire feeding device controls the introduction of the laser guide wire along the flexible ureteroscope. In addition, a lifter provides necessary height adjustment according to the patient's physical condition. The control box provides an intuitive operation interface for surgeons.

The present invention is directed to a surgical instrument with a robotics system, a memory device and an end effector having an elongate channel, knife position sensor(s) and a firing bar coupled to a knife. In response to drive motions initiated by the robotics system, the firing bar may translate within the elongate channel. As the firing bar translates, the sensor(s) transmit a signal to the memory device. The position of the knife may be determined from the output signals and may be communicated to the robotics system or instrument user. The sensors may be Hall Effect sensors.

A catheter driving system is configured to navigate various medical catheters through complex narrow tissue openings or between organs and tissue planes, which may include lung bronchi pathway openings of 3 millimeters or less. These catheters may comprise one or more sections and optional steering cables. The catheter driving device comprises at least one rotary actuator configured to rotate at least one region of the catheter and at least one steering cable actuator configured to apply flexing force to control the direction of the catheter. To prevent the rotary actuator from tangling the steering cables, the system is further configured to rotate at least one steering cable along with the rotation of the rotated catheter region. This cable rotation may be 1:1 (e.g., synchronously) with the catheter rotation or may be configured to vary somewhat to accommodate catheter twisting, spring action, windup, and other effects.

A robotic system includes a medical instrument comprising an elongate shaft dimensioned to be disposed at least partially within an access sheath and control circuitry configured to cause the elongate shaft to be retracted at least partially within the access sheath, determine a position of a distal end of the elongate shaft relative to the access sheath, and modify a speed of retraction of the elongate shaft based on the determined position of the distal end of the elongate shaft relative to the access sheath.
