A system for assisting endoscope tracking used to track a travel path of an endoscope probe within an organ includes three position sensors and three distance sensors which are surrounding an endoscope probe, and a computing device. The said three position sensors respectively sense a first coordinate, a second coordinate and a third coordinate relative to a navigation origin. The said three distance sensors respectively sense a first distance, a second distance and a third distance apart from an inner wall of the organ. The computing device obtains a position coordinate of the endoscope probe relative to the navigation origin according to the first coordinate, the second coordinate and the third coordinate. The computing device further determines whether to send a warning message according to the first distance, the second distance and the third distance.

Aspects of the present disclosure are presented for managing simultaneous outputs of surgical instruments. In some aspects, methods are presented for synchronizing the current frequencies. In some aspects, methods are presented for conducting duty cycling of energy outputs of two or more instruments.

This invention is in relation to a thermosensitive plate for qualitative measurement of the component temperature of living organisms by means of thermosensitive silica used in the field of medical surgery.

A probe generates location signals, and has an electrode at a distal end that acquires from heart chamber surface positions electrical signals due to a conduction wave traversing the surface. A processor derives LATs from the electrical signals, calculates a first time difference between LATs at a first pair of positions and a second time difference between LATs at a second pair of positions. The processor calculates first and second LAT-derived distances as products of the first and second time differences with a conduction wave velocity, identifies an arrhythmia origin at a surface location where a first difference in distances from the location to the first pair of the positions is equal to the first LAT-derived distance, and a second difference in distances from the location to the second pair of the positions is equal to the second LAT-derived distance, and marks the origin on a surface representation.

A robotic system is integrated with the laparoscope effectively creating a 3D scanner which can be used during laparoscopic surgery. This enables advanced surgical navigation and visualization to aid with the surgical process. It also acts as a core data set to be used by the Digital Health Platform. This acts as the starting point for Virtual Reality reconstruction of the surgical procedure for both real time surgical guidance and advanced AI/ML development. Furthermore, diagnostic capabilities could also be integrated into the system to enable real time diagnostic data to be generated for use during the procedure. Coupling the diagnostic capabilities with the vision system of the laparoscope and the ground truth reference coordinate system of the robot enables quick Augmented Reality visualization through the Digital Health Platform.

A tool path generator utilizes a solid body model of a volume to generate a tool path for a manipulator to remove material of the volume with an energy applicator in a semi-autonomous mode. A material logger monitors movement of the energy applicator according to a cutting path taken by a practitioner in the manual mode, identifies material of the volume to which the energy applicator has been applied in the manual mode, and updates the solid body model based on the identified material. The tool path generator modifies the tool path based on the updated solid body model such that, for the semi-autonomous mode, the modified tool path accounts for the identified material of the volume to which the energy applicator has been applied in the manual mode.

Systems and methods are described herein for resurfacing bones, and in particular, for detecting and resurfacing one or more femoroacetabular impingements (FAIs). A FAI resurfacing controller may be used to perform this detecting and resurfacing of FAIs. The FAI resurfacing controller may include a bone model generator to receive bone imaging and to generate a model of at least one osteophyte and of a surface of a native bone surrounding the at least one osteophyte. The FAI resurfacing controller may include an osteophyte identifier to set a virtual 3D boundary surface between native bone surface and the at least one osteophyte. The FAI resurfacing controller may include a resurfacing navigator to generate and output a navigation file. The navigation file may include the model with the 3D boundary surface between native bone surface and the at least one osteophyte.

During both invasive and non-invasive treatments and therapies, health professionals need to accurately locate areas of interest. Inaccuracies may mean that not all the area is treated, or the treatment is incomplete. Electro-magnetic and RFID (Radio-Frequency Identification) markers have been developed, but these are bulky and prone to failure. For example, any inaccuracy may result in an incomplete resection or removal of the lesion, requiring additional treatments. A magnetic field probe 100, 101 is provided for determining an angular disposition 180, 190 of an implantable magnetic marker 200, the probe comprising: a first magnetic sensor 110 close to the distal end 160, and a second magnetic sensor 120, closer to a proximal end 165, configured to determine two or more magnetic field vectors of the marker 200; the probe being further configured: to define two or more marker detection zones 170, 171, 172, 173, 174, extending from the distal end 160; to determine the angular disposition 180, 190 to the implantable marker 200; and to determine whether the angular disposition 180, 190 substantially coincides with one of the two or more marker detection zones 170, 171, 172, 173, 174, thereby determining that the marker falls within the one marker detection zones. By defining two or more marker detection zones, and configuring the probe to determine whether the magnetic marker appears to be within the one marker detection zone, a simplified and intuitive decision algorithm is provided for indicating the disposition of the marker relative to the probe.
