The tracking system is configured to provide tracking data representing multiple positions of the sensor in a spatial coordinate system. The computing device is configured to generate a data point cloud based on the tracking data, generate a parametric model corresponding to at least a portion of the vessel based on the data point cloud and store the parametric model in non-transitory memory.

A sphincter sizing instrument includes a body that defines a lumen and a shaft that longitudinally translates through the lumen relative to the body. The body includes opposing proximal and distal ends. The distal end includes a first magnetic coupling feature and a first mechanical coupling feature. The shaft includes opposing proximal and distal ends and a coupler coupled with the distal end. The coupler includes a second magnetic coupling feature and a second mechanical coupling feature. The second magnetic coupling feature is configured to attract and couple with the first magnetic coupling feature to form a magnetic connection. The second mechanical coupling feature is configured to couple with the first mechanical coupling feature to form a mechanical connection.

Medical or surgical devices, instruments, systems, and methods for use in optically sensing loads acting on a patient's anatomy may include a surgical device or instrument configured for insertion to a surgical site and an interrogator coupled to the surgical device or instrument via an optical fiber having a sensing area at a location of the surgical device or instrument at which a load is to be sensed. The measured load may be used as being indicative of a load acting on a patient's anatomy. Such measured or determined load may be used to make decisions before, during, or after a patient procedure.

A method for generating intraoperative surgical guidance during a knee arthroplasty includes: preceding resection of a first bone and a second bone in a knee of a patient, generating a first ligament tension curve for a first ligament in the knee; generating a second ligament tension curve for a second ligament in the knee; storing a first target tension curve for the first ligament based on the first ligament tension curve; and, succeeding resection of the first bone and succeeding placement of a first test implant on the first bone, generating a third ligament tension curve for the first ligament; characterizing a first phase difference between the third ligament tension curve and the first target tension curve; and in response to the first phase difference exceeding a threshold negative phase difference, outputting a first prompt to a surgeon to further resect the first bone proportional to the first phase difference.

An endodontic robotic surgical system is provided. The endodontic robotic surgical system includes a robot arm and an endodontic robotic surgical assembly electrically connected to the robot arm. The endodontic robotic surgical assembly includes a multiple-axis force sensing device, a treatment assembly and an assistive device. The treatment assembly includes a housing, a drawstring-positioning structure disposed on the housing, a plurality of drawstrings connected to the drawstring-positioning structure, and an endodontic surgical element fitted to the housing. The drawstring-positioning structure is electrically connected to the multiple-axis force sensing device. The assistive device is adapted to be put on a tooth structure in a human oral cavity. The drawstrings are connected to different points on the assistive device. An endodontic robotic surgical assembly is further provided.

In various embodiments, a surgical instrument, systems including the surgical instrument, and methods of use of the surgical instrument are disclosed. The surgical instrument includes a handle body extending from a proximal end to a distal end substantially along a longitudinal axis. The handle body defines a first channel sized and configured to receive a guide element therein. A plurality of indicators are formed on the handle body. Each of the plurality of indicators correspond to a size of one of a plurality of fixation elements sized and configured for insertion into a bone. A countersink element is coupled to a distal end of the body. The countersink element defines a second channel sized and configured to receive the guide element therethrough that is circumferentially located with and coupled to the first channel. The countersink element includes a head sized and configured to form a countersink in the bone.

Embodiments of a simulated valve device can be used to determine whether a valve device would fit within a particular airway. The simulated valve device can include a shaft having at least one strut extending radially therefrom. The strut and at least part of the shaft can be surrounded by a membrane for viewing through a bronchoscope. In some embodiments, the membrane can include markings for viewing by a user.

This disclosure includes surgical depth gauges and related methods. Some gauges have a probe assembly including a probe having proximal and distal ends, the distal end including one or more prongs, each having a distal-most tip, being movable between a retracted position and a deployed position in which the tip is farther from a longitudinal axis of the probe than when the prong is in the retracted position, and being biased toward the deployed position. Some probe assemblies include a cannula having proximal and distal ends, where the probe is disposable within the cannula such that moving the distal end of the probe toward and away from the distal end of the cannula causes each of the prongs to move between the retracted and deployed positions. Some depth gauges include a sleeve disposable over the probe assembly.

A spinal construct comprises at least one member that defines a first implant cavity and a second implant cavity oriented transverse to the first implant cavity. The at least one member has a surface that includes a lock disposed with the first implant cavity. Systems, implants, surgical instruments and methods of use are disclosed.

A surgical drill for drilling a hole in a workpiece includes a housing, a probe moveably mounted to the housing, and a transducer assembly. The transducer assembly includes a gear coupled to the probe and at least two rotational sensor devices coupled to the gear to determine an amount of movement of a probe relative to a housing to determine a bore depth of the hole. The gear has reference point having an angular path of rotation about a gear axis subdivided into separate first and second arcuate regions. A first sensor device is configured to detect a rotational position of the reference point in the first arcuate region, and a second sensor device is configured to detect a rotational position of the reference point in at least the second arcuate region, with the first sensor device incapable of detecting the reference point in the second arcuate region.
