A flexible chain implant for insertion into an interior volume of a vertebral body. The implant may be implanted in an insertion position for sliding through a cannula and is flexible for packing into the interior volume in an implanted configuration. The implant randomly separates in the implanted configuration. The implant includes a top member and a bottom member, wherein the top and bottom members are coupled to one another at a coupled portion. The top and bottom members preferably each include an inner surface such that the inner surfaces include a plurality of alternating projections and recesses so that the projections are received within the recesses in an insertion position. Alternatively, the implant may include a plurality of substantially non-flexible bodies and a plurality of substantially flexible links interconnecting the bodies. The non-flexible bodies include a plurality of facets and/or abutment surfaces.

Flexible chain implants and instrumentation

Self-locating active markers (SLAMs) can locate themselves with respect to patient's internal anatomy and be physically located and visible in an operating room (OR) coordinate space, which can increase precision of co-registration between augmented reality (AR) systems and medical imaging. Each SLAM may include 9-axis accelerometers and ultrasound technology to locate themselves by orientation and distance to internal skeletal and/or soft tissue anatomy. Multiple SLAMS affixed to skin near operative site at a location visible to a surgical navigation system and/or the surgeon's AR Headset during a procedure may report relative distance changes between their location and internal skeletal anatomy in order to maintain surgical navigation system or AR coordinate system co-registration to the imaged internal coordinate systems. Sequential time of flight calculations from ultrasound array alone or in combination with 9-axis accelerometer data may be used.

Self-locating, active markers for navigated, augmented reality, or robotic surgery

Systems and methods are disclosed in which changes in the position and/or orientation of an anatomical structure or of a surgical tool can be measured quantitatively during surgery. In some embodiments, a surgical electronic module can be configured to attach to a surgical device, to continually detect changes in a position and/or orientation of the surgical device during surgery, and to communicate the changes to a user. In this way, where the surgical device is attached to a portion of a patient's anatomy and/or is used to manipulate the patient's anatomy, the surgical electronic module can detect changes in the position and/or orientation of said anatomy. In embodiments where more than one module is used during surgery, the modules can continually detect changes in their positions and/or orientations relative to one another, which correspond to changes in relative positions and/or orientations of the surgical devices to which the modules are attached.

Systems and methods for intraoperatively measuring anatomical orientation

Systems and methods are disclosed in which changes in the position and/or orientation of an anatomical structure or of a surgical tool can be measured quantitatively during surgery. In some embodiments, the systems and methods disclosed herein can make use of inertial motion sensors to determine a position or orientation of an instrument or anatomy at different times and to calculate changes between different positions or orientations. In other embodiments, such sensors can be utilized in conjunction with imaging devices to correlate sensor position with anatomical landmarks, thereby permitting determination of absolute angular orientation of a landmark. Such systems and methods can facilitate real-time tracking of progress during a variety of procedures, including, e.g., spinal deformity correction, etc.

A surgical tool is disclosed. The surgical tool includes a functional tool, a functional tip, at least one sensor, and a control unit. The functional tool has a shaft and a distal end. The functional tip is positioned at the distal end of the housing; at least one sensor is configured to generate a first signal indicative of at least one of an acoustic signal or a vibration signal generated by the functional tool. The control unit receives the first signal, analyzes the first signal to determine tissue type in contact with the functional tip and supplies a second signal to the functional tool to control at least one operation of the functional tool based upon the tissue type in contact with the functional tip.

Surgical tool with feedback

A neurophysiological monitoring system includes at least one surgical instrument having at least one magnetometer and a control unit configured to receive magnetic field data generated by the at least one magnetometer. The control unit may provide stimulation to a nerve at a known stimulation time and receive magnetic field data from the at least one magnetometer indicative of a response to stimulation of the nerve at a receive time. An interpretation of the magnetic field data based upon the receive time and the stimulation time may be generated.

Intraoperative magnetometry monitoring system

Electronic devices that detect their position and/or orientation with respect to earth's frame of reference are described. A coupler can removeably maintain the electronic devices in physical proximity of one another. Each electronic device can have a housing and the coupler can be included on the housing and arranged to physically connect the housing of the electronic device to the housing of at least one other electronic device. Alternatively, the coupler can be a packaging that maintains the electronic devices in physical proximity of one another. Each electronic device can be calibrated using the orientation or position information obtained by other electronic devices maintained by the coupler. Further, each electronic device can include a power source that remains inactive until the device is ready for use.

Method and apparatus for intraoperative measurements of anatomical orientation

A device for spinal surgery that may be used for tightening a locking cap onto at least a portion of a pedicle screw. The device may include a torque-generating body having a proximal end and an opposing distal end and a drive shaft rotatably driven by the torque-generating body. A proximal end of the drive shaft may be operatively engaged to the distal end of the torque-generating body and an opposing distal end of the drive shaft may engage at least a portion of one of the locking cap and the pedicle screw. An anti-torque device is provided that has an elongated and generally hollow member defining a longitudinal axis. The member has a proximal end and an opposing distal end, where the proximal end of the anti-torque device may be fixed from rotating relative to at least a portion of the torque-generating body and the distal end may be fixed from rotating relative to a spine rod or a pedicle screw.

Tightening device for spine surgery

A method and apparatus are disclosed. The method includes removably attaching an input device of a surgical feedback system to a surgical tool having a handle. The input device has at least one sensor configured to collect a plurality of original signals. The plurality of original signals has at least one of an acoustic signal or a vibration signal. The surgical tool contacts tissue of a patient. And, a notification of the type of tissue being contacted by the surgical tool is received.

Accuracy enhancing systems, devices and methods are provided using data obtained from inertial measurement units (IMUs). IMUs are provided on one or more of a patient, surgical table, surgical instruments, imaging devices, navigation systems, and the like. Data from sensors in each IMU is collected and used to calculate absolute and relative positions of the patient, surgical table, surgical instruments, imaging devices, and navigation systems on which the IMUs are provided. The data generated by the IMUs can be coupled with medical images and camera vision, among other information, to generate and/or provide surgical navigation, alignment of imaging systems, pre-operative diagnoses and plans, intra-operative tool guidance and error correction, and post-operative assessments.
