A system for creating at least one model of a bone and implanted implant comprises a processing unit; and a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for: obtaining at least one image of at least part of a bone and of an implanted implant on the bone, the at least one image being patient specific, obtaining a virtual model of the implanted implant using an identity of the implanted implant, overlaying the virtual model of the implanted implant on the at least one image to determine a relative orientation of the implanted implant relative to the bone in the at least one image, and generating and outputting a current bone and implant model using the at least one image, the virtual model of the implanted implant and the overlaying.

Patient-specific instrumentation for implant revision surgery

A surgical assistance system includes a processing unit; and a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for: obtaining a video feed of a surgical procedure and monitoring the surgical procedure from the video feed; detecting, from an image processing of the video feed, a condition requiring a deviation from the surgical procedure, the deviation being defined as being outside of a standard surgical flow; and outputting a recommendation of deviation by intra-operatively providing the recommendation to an operator of the surgical procedure.

Surgery assistance system

Methods and surgical system for performing a surgical procedure. The surgical system includes a robotic system with a robotic arm having a surgical instrument attached thereto. A computer system of the robotic system receives at least one image and forms a model of a surgical area. A computer operated tracking system of the robotic system obtains position data related to a patient's bone from tracking elements. Based on the model of the surgical area and the tracked bone position, the robotic arm then performs the surgical procedure with the surgical instrument, and the robotic system adjusts the procedure as a result of the tracked bone position.

Robotic shoulder repair and reconstruction

A method or system for storing an instrument, such as in a sterile environment. For example, a surgical robotic system may include a surgical robotic arm and a sterilization unit enclosing the sterile environment and storing the instrument. A processor may be used to determine that the instrument is needed (e.g., during a surgical procedure or portion of a surgical procedure or for a future surgical procedure or portion of a future surgical procedure). The processor may provide access to the instrument.

Robotic device and sterilization unit for surgical instrument

A surgical sensor system for collecting internal patient data comprises a sensor module comprising a housing and a sensor disposed within the housing, and an attachment device comprising a socket for receiving the housing and an exterior anchor feature for attaching the attachment device to biological matter. A method of implanting a sensor module for use with an orthopedic implant device comprises making an insertion portal in anatomy of a patient, positioning a sensor module in the anatomy in a first position relative to the insertion portal, and positioning an orthopedic implant in the anatomy in a second position relative to the insertion portal such that the orthopedic implant is separate from the sensor module.

Independently implantable sensors for orthopedic implants

Systems and methods may be used to perform robot-aided surgery. A system may include a robotic controller to monitor a position and orientation of an end effector coupled to an end of a robotic arm. The robotic controller may apply a force to a bone using the end effector, such as via a soft tissue balancing component. The robotic controller may determine soft tissue balance using information from a tracking system, such as a position of a first tracker affixed to the bone. The soft tissue balance may be output, such as to a display device.

Soft tissue balancing in articular surgery

Systems and methods for femoral medial condyle spherical center identification and tracking are described herein. Once the spherical center of the medial condyle is identified, the spherical center is tracked using a pin or internal reference. The spherical center may be used to provide a key kinematic motion reference, such as when the medial condyle is adjusted during a surgical procedure. The tracking may be used to provide optical tracking, inertial tracking, or other tracking. In contrast with surface-mounted optical trackers, the spherical center tracking is not lost during resection (e.g., removal) of a bone surface. Tracking the medial condyle spherical center may reduce or eliminate the need for a surface-mounted optical tracker or preoperative 3-D modeling or of the joint.

Femoral medial condyle spherical center tracking

A system and method may be used to evaluate soft tissue. A knee arthroplasty soft tissue evaluation may use an adjustable spacer, such as varying sized physical spacers or an inflatable bladder, along with a sensor to measure force, pressure, gap distance, or the like during a range of motion test. A method may include maintaining an equal pressure or gap distance for a medial component and a lateral component of an adjustable spacer during a range of motion test. Information, including, for example a maximum or minimum gap distance or pressure may be determined during the range of motion test. The determined information may be output for display or used to update a surgical plan.

Soft tissue balancing in robotic knee surgery

A system and method may be used to evaluate soft tissue. A hip joint evaluation may use an adjustable spacer, such as varying sized physical spacers or an inflatable bladder, along with a sensor to measure force, pressure, gap distance, or the like, for example during a range of motion test. A method may include using a maximum pressure during the range of motion test to determine a maximum pressure during the range of motion test. The maximum pressure may be output for display on a user interface.

A system for tracking at least one object in computer-assisted surgery may include a processing unit and a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for: obtaining orientation data from at least one inertial sensor unit on at least one object; concurrently obtaining position and orientation data for a robot arm relative to a frame of reference; registering the at least one object with the robot arm to determine a position of the at least one object in the frame of reference; and continuously tracking and outputting the position and orientation of the at least one object in the frame of reference, using the orientation data from the at least one inertial sensor unit on the at least one object and the position and orientation data for the robot arm.

Tracking system for robotized computer-assisted surgery

A system for controlling a tourniquet pressure may have a processing unit and a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit. The system may obtain ultrasound readings indicative of a blood flow in a limb having a tourniquet applying pressure on the limb; determine characteristic(s) of the blood flow from the ultrasound readings; and adjust a tourniquet pressure as a function of the at least one characteristic of the blood flow. An integrated robotic surgery system is also provided.

To address technical problems facing knee arthroplasty resection validation, the present subject matter provides a tracked knee arthroplasty instrument for objective measurement of resection depth. By performing a precise comparison between the location of the tracked knee arthroplasty instrument and a reference location, the knee arthroplasty instrument measures and validates each tibial and femoral resection. To address technical problems facing validation of joint laxity following knee arthroplasty, the tracked knee arthroplasty instrument is shaped to validate the flexion gap and extension gap. When the tracked knee arthroplasty instrument is inserted between the resected tibial plateau and femoral head, the instrument shape validates whether the desired flexion gap and extension gap have been achieved.
