20110263971 | Reconfigurable Navigated Surgical Tool Tracker - A reconfigurable tracking arrangement for an object includes a repositionable mounting arrangement that may be configured to releasably connect to an object for selectively positioning the same. The mounting arrangement may further include a first piece attached to the object and a second piece that can be repositioned relative to the first piece. In addition, the mounting arrangement may be configured to be secured in at least two stable pre-configured positions about the object. | 10-27-2011 |
20110264107 | Navigated Freehand Surgical Tool and Kit - 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. | 10-27-2011 |
20120016339 | Method and Apparatus for Intraoperative Cardiac Tissue Injection - 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. | 01-19-2012 |
20120123418 | STABILIZERS FOR SURGICAL TOOLS - Described herein are stabilizers for surgical tools. One aspect provides a surgical tool stabilizer, comprising: a support configured to engage at least a portion of a surgical tool and configured to receive at least a portion of a tracking system; and a retractable stabilizer configured to surround at least a portion of an end effector of said surgical tool. Other embodiments are described. | 05-17-2012 |
20140135791 | SYSTEMS AND METHODS FOR NAVIGATION AND CONTROL OF AN IMPLANT POSITIONING DEVICE - 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. | 05-15-2014 |
20140278322 | SYSTEMS AND METHODS FOR USING GENERIC ANATOMY MODELS IN SURGICAL PLANNING - Systems and methods for generating a surgical plan for altering an abnormal bone using a generic normal bone model are discussed. For example, a system for planning a surgery on an abnormal bone can include a model receiver module configured to receive a generic normal bone model. The generic normal bone model, such as a parametric model derived from statistical shape data, can include a data set representing a normal bone having an anatomical origin comparable to the abnormal bone. An input interface can be configured to receive an abnormal bone representation including a data set representing the abnormal bone. A surgical planning module can include a registration module configured to register the generic normal bone model to the abnormal bone representation by creating a registered generic model. A surgical plan formation module can be configured to identify one or more abnormal regions of the abnormal bone using the registered generic model. | 09-18-2014 |
20140282194 | SYSTEMS AND METHODS FOR DETERMINING A POSITION FOR PLACING OF A JOINT PROSTHESIS - 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. | 09-18-2014 |
20150250553 | COMPUTER-AIDED PROSTHESIS ALIGNMENT - Systems and methods for computer-aided alignment and positioning of a prosthesis component onto a target host bone, such as in joint resurfacing arthroplasty, are discussed. A system for can include a processor unit and a user interface unit. The processor unit can receive a target bone model including a first data set representing a target bone surface, and a prosthesis model including a second data set representing a prosthesis surface. The prosthesis, when positioned against the target bone, is configured to at least partially replace the articulation surface. The processor unit can generate an articulation interface representation that indicates spatial misalignment between one or more portions of the prosthesis surface and one or more portions of the target bone surface when the prosthesis model is positioned against the target bone model. | 09-10-2015 |
