Abstract: Examples of an orthopedic surgical device for use in operating on a target bone and methods for operating a system for use in orthopedic surgery on a bone are generally described herein. An orthopedic surgical device can include an primary positioning block, and a secondary positioning component removably coupled to the primary positioning block. The secondary positioning component can be configured to: engage a prepared engagement feature machined into the target bone, and guide the primary positioning block to a predetermined position on a target bone. The orthopedic surgical device can include a first cutting block configured to: removably couple to the primary positioning block, and guide a cutting tool to cut the target bone.

Abstract: Systems and methods for positioning a cut guide using navigation-based techniques are discussed. For example, a system for use in an orthopedic surgery on a target bone can comprise a cut guide adjustably positionable onto the target bone via two or more coupling receptacles created on the target bone. The coupling receptacles can include one or more guide members and a plurality of landing members. The system also includes an input interface that can receive a target bone representation, and a model receiver module that can receive a generic post-coupling bone model. The target bone representation can include a data set representing two or more landing sites of the target bone, and the generic post-coupling bone model can include a data set representing a bone having two or more coupling receptacles each sized, shaped or otherwise configured to receive and secure the respective coupling feature of the landing members.

Abstract: The apparatus provides for injecting therapeutic agents at precise locations into the bodily tissue. The apparatus comprises an end effector that is guided to a precise location by motion controllers on a handle. At a precise location, the end effector attaches via a vacuum to the cardiac tissue. A flexible needle is advanced through a deflecting tunnel in the end effector to a desired depth. A therapeutic agent is then introduced via the flexible needle into the cardiac tissue. All these manipulations can be controlled by one hand and can be viewed via imaging methods.

Abstract: A handpiece arrangement for a tool having a retaining member configured to receive a portion of the tool in a secure position, a guard configured to cover a portion of the tool, at least one mounting member configured to receive a portion of a tracking system and an actuator mounted to the handpiece. The actuator may be configured to control the exposure of the tool. A navigated surgery kit is also provided including a tracking system, a tool in communication with the tracking system, a platform in communication with the tracking system and the tool. The platform may have a processor, a computer readable storage medium having computer readable program code configured to selectively control shaping of an object with the tool via at least one hidden object associated with a predetermined navigated surgical operation.

Abstract: Systems and methods for virtual implant placement to implement joint gap planning are discussed. For example, a method can include operations for receiving a first implant parameter set based on a surgical plan that was generated while moving the joint through a range of motion. The method can include generating a first set of candidate implant parameter sets that are the result of an incremental change, relative to the first implant parameter set, to at least one parameter of the first parameter set. The method can include calculating a result for at least one candidate implant parameter set and providing a graphical representation of the result according to at least one candidate implant parameter set. The result can be color-coded to correlate to a candidate implant parameter set. The display can include color-coded user interface controls to allow a user to execute incremental changes corresponding to candidate implant parameter sets.

Abstract: Systems and methods for navigation and control of an implant positioning device are discussed. For example, a method can include operations for accessing an implant plan, establishing a 3-D coordinate system, receiving tracking information, generating control signals, and sending the control signals to the implant positioning device. The implant plan can include location and orientation data describing an ideal implant location and orientation in reference to an implant host. The 3-D coordinate system can provide spatial orientation for the implant positioning device and the implant host. The tracking information can identify current location and orientation data within the 3-D coordinate system for the implant positioning device and implant host during a procedure. The control signals can control operation of the implant positioning device to assist a surgeon in positioning the implant according to the implant plan.

Abstract: An augmented reality device to combine a real world view with an object image. An optical combiner combines the object image with a real world view of the object and conveys the combined image to a user. A tracking system tracks one or more objects. At least a part of the tracking system is at a fixed location with respect to the display. An eyepiece is used to view the combined object and real world images, and fixes the user location with respect to the display and optical combiner location.
