Provided in accordance with the present disclosure are systems for identifying a position of target tissue relative to surgical tools using a structured light detector. An exemplary system includes antennas configured to interact with a marker placed proximate target tissue inside a patient's body, a structured light pattern source, a structured light detector, a display device, and a computing device configured to receive data from the antennas indicating interacting with the marker, determine a distance between the antennas and the marker, cause the structured light pattern source to project and detect a pattern onto the antennas. The instructions may further cause the computing device to determine, a pose of the antennas, determine, based on the determined distance between the antennas and the marker, and the determined pose of the antennas, a position of the marker relative to the antennas, and display the position of the marker relative to the antennas.

The present disclosure includes systems for surgical navigation, the system comprising a tracking array attachable to a medical instrument, an image capturing device, and a navigation system that communicates with the image capturing device and generates tracking information of the medical device.

Systems and methods of providing augmented reality assisted surgery are disclosed. Certain aspects provide a method including generating a virtual scene comprising one or more virtual elements comprising one or more anatomical elements corresponding to one or more anatomy parts. The method further includes identifying one or more references in an actual physical scene comprising the one or more anatomy parts. The method further includes registering the virtual scene to the one or more references to generate an augmented scene. The method further includes displaying the augmented scene on a display device.

A sensor coil assembly comprises a positioning sensor comprising a wound coil formed by a first conductive wire segment wound around a longitudinal axis. The first conductive wire segment can include a first coil end and a second coil end. A second conductive wire segment can extend from the first coil end of the first conductive wire segment. The second conductive wire segment can be wound around a first bobbin. A third conductive wire segment can extend from the second coil end of the first conductive wire segment. The third conductive wire segment can be wound around a second bobbin.

A method and device for determining a radius of a spherically shaped surface portion of a tip of an instrument. A first pose of a first tracker and a second pose of a second tracker may be determined while the spherically shaped surface portion is in abutment with a calibration structure. A reference position of a first reference point relative to the second tracker may be determined when the first tracker is in the first pose and the second tracker is in the second pose based on the first pose, the second pose, and a first predetermined relationship. A third pose of the first tracker and a fourth pose of the second tracker may be determined. The radius of the spherically shaped surface portion may be determined based on the third pose, a second predetermined relationship, a reference position, the fourth pose, and an opening angle.

Devices, systems, and methods for automatically exchanging a first end-effector on a robot arm with a second end-effector housed in a docking station. The first end-effector has a clamp that either engages or disengages the robot arm based upon an application of force of the robot arm onto the end-effector. The clamp has a spring loaded clip that disengages the first end-effector to allow the robot arm to move away from the released first end-effector. The robot arm is configured to automatically move to a port of a docking station housing the desired second end-effector using magnetic coils on the robot arm and the docking station to guide the robot arm.

A device for interventions within the body, the device comprising: an end piece 6 for insertion into the body at a distal end thereof, the end piece 6 including a rigid lumen for holding an instrument 10 and guiding the instrument 10 to the distal end of the end piece; and a body section 4 supporting the lumen and being rigidly connected thereto, the body section including a navigation array 14 for guidance of the device using a surgical navigation system and/or including an anchor point 20 for a standard navigation array.

A method performed by a computing system comprises receiving shape information for an elongate flexible portion of a medical instrument. The medical instrument includes a reference portion movably coupled to a fixture having a known pose in a surgical reference frame. The fixture includes a constraint structure having a known constraint structure location in the surgical reference frame. The elongate flexible portion is coupled to the reference portion and is sized to pass through the constraint structure. The method further includes receiving reference portion position information in the surgical reference frame; determining an estimated constraint structure location in the surgical reference frame from the reference portion position information and the shape information; determining a correction factor by comparing the estimated constraint structure location to the known constraint structure location; and modifying the shape information based upon the correction factor.

Provided herein are systems, devices, assemblies, and methods for generating exciter signals, for example, to activate a remotely located tag. The systems, devices, assemblies, and methods find use in a variety of application including medical applications for the locating of a tag in a subject.

A smart marking system for a surgical video and a method thereof are disclosed. The image recognition is performed for each surgical video to generate object information corresponding to each surgical video. The object information is used as feature data of the surgical video corresponding thereto. After a video to be analyzed is loaded, eigenvalue analysis and statistics are performed according to the video to be analyzed and all the feature data to calculate a similarity rate between the video to be analyzed and each surgical video. A surgical name corresponding to the surgical video with the highest similarity rate is selected to mark as a surgical name corresponding to the video to be analyzed. The video to be analyzed and the surgical name corresponding thereto are stored in a database as the surgical video. Thus, the efficiency of marking the surgical videos is improved.
