A system for tracking an instrument in computer-assisted surgery, comprising: 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 intraoperatively at least one image of an instrument having a tracker thereon, the tracker having optical elements thereon arranged in a given pattern; calibrating the instrument by image processing the at least one image to record the given pattern relative to the instrument; and tracking the instrument optically after the calibrating by obtaining images of the given pattern of optical elements.

The present subject matter provides an orthopedic instrument may include a first end portion, a handle portion and an optical tracker. The first end portion is configured as a validation device having at least a first surface configured to validate a first resected surface of a bone of the knee. The first end portion has one or more surfaces with a plurality of teeth configured to remove material from the first resected surface. The handle portion is coupled to the first end portion. The optical tracker is coupled to the handle portion.

A system may include an implantable device having at least a first sensor configured to collect first data regarding one or more characteristics of a bone of a patient, wherein the implantable device is configured for implantation in a medullary canal of the tibia. The system may include an attachment member configured to couple with the implantable device when the implantable device is implanted in the medullary canal of the tibia. The system may further include a targeting device moveably coupled to the attachment member, wherein the targeting device is configured to reference a distal anatomy of a leg, and wherein the targeting device has at least a second sensor configured to collect second data regarding at least a position of the targeting device.

Patient-specific instrumentation for reverse shoulder surgery includes a jig having a contact surface including a patient-specific surface portion negatively shaped as a function of a glenoid surface and configured to be applied against the glenoid surface in unique complementary engagement. A first throughbore opens into the contact surface, the first throughbore having an axis corresponding to a first altered bone plane in the glenoid surface. A second throughbore opens into the contact surface, the second throughbore having an axis corresponding to a second altered bone plane in the glenoid surface. The axes of the first throughbore and of the second throughbore are not parallel to one another.

An reaming system can be connectable to a robotic surgical system including an end effector of a robotic arm. The reaming system can include a reaming guide and a reamer. The reaming guide can include a body releasably couplable to the end effector at a proximal portion of the body and a housing located at a distal portion of the body. The reamer can be operable to ream bone. The reamer can include a support releasably couplable to the housing to secure the reamer to the reaming guide and the end effector. The reamer can include a cutting head connected to the support, the cutting head rotatable with respect to the housing when the support is coupled to the housing.

A knob including an outer housing, a first magnet, a second magnet, a first crown and a second crown. The second magnet and the first magnet are configured to exert a repulsive force with respect to one another. The first crown positioned within the outer housing and restrained from translation relative to the outer housing. The second crown is coupled to the second magnet. The second crown is rotatable with the outer housing. The second crown has a second plurality of teeth on a second side thereof that interface with and selectively engage the first plurality of teeth on the first side of the first crown. The second crown overcomes the repulsive force between the first magnet and the second magnet and translates relative to the outer housing and the first crown when the first crown is threaded onto the first medical instrument to a predetermined torque.

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.

A surgical tool assembly may include a first component, a second component, a tracker device connected at least to the first component. A quick connect system for releasably connecting the first component to the second component, the quick connect system including a male and female engagement, a latch mechanism for latching the first component to the second component. Complementary features are on the first component and on the second component to ensure a planned positional alignment between the first component and the second component upon latching of the male and female engagement, for tracking of the second component with the tracker device.

A system for managing surgical hardware in computer-assisted surgery 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 for: obtaining at least one post-surgery image of a plurality of instruments used in a surgical procedure, after the surgical procedure is completed and before the plurality of instruments are stored in a storage device; processing the at least one post-surgery image to identify the instruments of the plurality; and outputting data relating to a position of at least one of the instruments in the storage device to assist a user in storing the at least one instrument.

A device for registering a bone for a robotic knee arthroplasty with a surgical robot can include a plate and a registration device. The plate can be engageable with the bone and can include a lateral portion, a medial portion, and a hinge. The registration device can be connected to the plate and can be configured to interface with the surgical robot for registration of the plate and the bone.
