A system with integrated tracking includes a procedure-specific hardware component (112 or 116) disposed at or near a region of interest. A field generator (114) is configured to generate a field with a field of view covering the region of interest. A mounting device (115) is connected to the field generator and is coupled to the procedure-specific hardware. The field generator is fixedly positioned by the mounting device to permit workflow access to the region of interest without interfering with the field generator and to provide a known position of the field generator relative to the region of interest. A tracking device (110) is configured to be inserted in or near the region of interest to be tracked within the field of view of the field generator to generate tracking data.

Systems, methods and devices for use in tracking are described, using optical modalities to detect spatial attributes or natural features of objects, such as, tools and patient anatomy. Spatial attributes or natural features may be known or may be detected by the tracking system. The system, methods and devices can further be used to verify a calibration of a tool either by a computing unit or by a user. Further, the disclosure relates to detection of spatial attributes, including depth information, of the anatomy for purposes of registration or to create a 3D surface profile of the anatomy.

Disclosed are systems and methods of lymphatic specimen tracking, visualization, and lymph node drainage pathway determination. An exemplary method includes receiving computed tomographic (CT) image data corresponding to a CT scan, generating a three-dimensional (3D) model of at least a portion of a patient's body based on the CT image data, identifying one or more lymph nodes in the 3D model, performing a registration of the 3D model with one or more physical locations in the patient's body, determining an expected lymph node drainage pathway away from a region of interest through one or more lymph nodes, and displaying the 3D model and the expected lymph node drainage pathway.

A system includes a console assembly, a trocar assembly operably coupled to the console assembly, a camera assembly operably coupled to the console assembly having a stereoscopic camera assembly, and at least one rotational positional sensor configured to detect rotation of the stereoscopic camera assembly about at least one of a pitch axis or a yaw axis. The console assembly includes a first actuator and a first actuator pulley operable coupled to the first actuator. The trocar assembly includes a trocar having an inner and outer diameter, and a seal sub-assembly comprising at least one seal and the seal sub-assembly operably coupled to the trocar. The camera assembly includes a camera support tube having a distal and a proximal end, the stereoscopic camera operably coupled to the distal end of the support tube and a first and second camera module having a first and second optical axis.

An implant delivery system includes a catheter, an implant, and a push body. The catheter extends from a first proximal end to a first distal end. The catheter defines an inner lumen extending through the first distal end. The implant includes a second proximal, a second distal end, and a plurality of resilient barbs. The implant is slidably housed within the inner lumen. The implant is compressed in the inner lumen such that the implant bears against an inner diameter of the inner lumen and the implant is retained within the inner lumen by friction. The push body is slidably housed within the inner lumen of the catheter. The push body is adjacent to the second proximal end of the implant.

A wireless localization system including a pad with an exciter coil and a sensor coil, a tool or surgical robot including a wireless tag configured to generate a signal in response to a magnetic field generated by the exciter coil. The signal is detected by the sensor coil and a processor configured to determine the location of the tool.

An electromagnetic intramedullary nail screw positioning system is used to assist an orthopaedic surgeon to correctly aligned a screw drill guide with a screw receiving aperture in an intramedullary nail during surgery. However due to the large number of different types of intramedullary nail, the system must be calibrated during each surgery. An improved calibration system is described that no longer requires the surgeon to perform the calibration during the surgery in order to save time and improve robustness. The system is periodically calibrated and a memory stores offset information for a range of nails types relative to a reference nail. During surgery, the surgeon enters a nail identifier, and the system looks up the associated offset and applies this offset to the measured signals to guide alignment of the screw drill guide with the screw receiving aperture.

A surgical bone cutting device, including a handle configured to facilitate operation and control of said device by an operator, and an elongated hollow member extending from the handle, the hollow member having a proximal end and a distal end; wherein the hollow member includes an opening at the distal end thereof and a rotatable cutting element extending through the opening, and wherein the hollow member includes a first bend at the proximal end thereof, such that the part of the hollow member distal to the proximal bend is offset a central axis of the hand.

The invention relates to a surgical instrument with an instrument handle, an instrument shank connected to the instrument handle, an instrument tip with a work point, which instrument tip is connected to the instrument shank, and a first locator arranged on the instrument handle or the instrument shank. During a use of the surgical instrument, the instrument shank can be deflected, e.g. on account of transverse forces, at least between the first locator and the work point. A second locator is arranged at a distance from the first locator and, by comparison with the latter, closer to the work point, wherein the second locator is designed to detect five degrees of freedom.

In one embodiment, a medical apparatus, includes a medical instrument configured to move within a passage in a body of a patient, a position tracking system to track coordinates of the medical instrument within the body, a display screen, and a processor to register the position tracking system and a 3D computerized tomography (CT) image of at least a part of the body within a common frame of reference, find a 3D path of the medical instrument through the passage from a start point to a termination point within the common frame of reference, compute a direction to the 3D path from the medical instrument responsively to the tracked coordinates, and render and simultaneously display on the display screen respective 2D CT slices, based on the 3D CT image, including respective 2D indications of the direction to the 3D path from the instrument projected onto the respective 2D CT slices.
