SURGICAL DEVICES, SYSTEMS, AND METHODS USING MULTI-SOURCE IMAGING

In general, devices, systems, and methods for multi-source imaging are provided.

System for determining the shape of a bendable instrument

A system comprises an instrument having a bendable portion with first and control elements extending in the bendable portion and a control system operably coupled to an actuator and a sensor. The control system operates to, while the bendable portion is in a neutral position, command the actuator to move the first control element a first amount until slack is removed from the first control element and command the actuator to move the second control element a second amount until slack is removed from the second control element. The control system also receives a first control element calibration position after moving the first control element the first amount and receives a second control element calibration position after moving the second control element the second amount. The control system also commands the actuator to bend the bendable portion from the neutral position and determine a resulting shape of the bendable portion.

Catheter with removable vision probe

A robotic system comprises an instrument including proximal distal sections. 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 record a position of a working configuration of the distal tip, determine, based on a sensor signal, a movement of the distal tip in response to insertion of a probe into the main lumen, and 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 to return the distal tip towards the working configuration recorded before the movement occurred.
