20100211077 | SURGICAL UNIVERSAL POSITIONING BLOCK AND TOOL GUIDE - A positioning block for use in knee surgery includes a rotational mounting removably engageable to the bone element by a multi-axial fastener such that the mounting element is selectively rotatable relative to the bone element about at least two substantially perpendicular axes of rotation. A guide body portion is engaged with the rotational mounting element such that it is translatable relative thereto along while being rotationally fixed relative to the mounting element. The guide body portion is moveable relative to the bone element in at least three degrees of freedom, the three degrees of freedom including at least two rotational degrees of freedom and at least one translational degree of freedom. A trackable member on the guide body portion is identified and tracked by a computer assisted surgery system. | 08-19-2010 |
20130317510 | PATIENT-SPECIFIC INSTRUMENTATION AND METHOD FOR ARTICULAR JOINT REPAIR - Patient-specific instrumentation for use when performing articular joint repair is provided. A patient-specific jig is adapted to be positioned over a bone at an articular surface thereof for assisting in preparing the bone surface for reception of a prosthesis. The jig comprises a bone contacting portion adapted to matingly contact a portion of the articular surface of the bone and a cutting slot adapted to receive therein a saw blade for resecting the articular surface of the bone. The cutting slot may be press-fitted into the opening of a cut guide. A patient-specific plate and a patient-specific rotational guide are also provided for guiding a positioning of the prosthesis over the resected surface of the bone. A method for manufacturing the patient-specific jig is further provided. | 11-28-2013 |
20140025348 | PATIENT-SPECIFIC INSTRUMENTATION FOR IMPLANT REVISION SURGERY - A system and method for generating a patient specific instrumentation jig model for implant revision comprises an anchor surface identifier to identify anchor surface(s) from a patient specific bone model of a bone requiring implant revision and from data related to an implanted implant on the bone. The anchor surface is in close proximity to the implanted implant. A PSI revision jig model generator generates a jig model using at least the identified anchor surface and a model of a replacement implant, the PSI revision jig model generator outputting a jig model comprising patient specific contact surface(s) corresponding to the identified anchor surface, and at least one tool interface portion positioned and/or oriented relative to the at least one contact surface, the at least one tool interface portion adapted to be interfaced to a tool altering the bone for subsequently installing an implant on the bone. | 01-23-2014 |
20140171967 | PROXIMITY-TRIGGERED COMPUTER-ASSISTED SURGERY SYSTEM AND METHOD - A computer-assisted surgery system comprises a first surgical device with a tracking unit tracked during a surgical procedure and adapted to perform a first function associated to the surgical procedure. A second surgical device is adapted to perform a second function associated to the surgical procedure. A triggered unit is triggered when the first surgical device and the second surgical device reach a predetermined proximity relation. A surgical procedure processing unit tracks the first surgical device. A trigger detector detects a triggering of the triggered unit. A CAS application operates steps of a surgical procedure. A controller commands the CAS application to activate a selected step associated with the second function in the surgical procedure when the trigger detector signals a detection. An interface displays information about the selected step in the surgical procedure. | 06-19-2014 |
20150073424 | GLENOID IMPLANT SURGERY USING PATIENT SPECIFIC INSTRUMENTATION - A pin placement instrument for placing a pin in a bone comprises an anatomical interface with a hook-like portion being opened in a lateral direction of the instrument to receive a bone therein in a planned position. A drill guide is connected to the anatomical interface and defining at least one guide slot in a longitudinal direction of the instrument. The guide slot has a lateral opening over its full length in the drill guide to allow lateral withdrawal of the instrument in said lateral direction with the pin placed in the bone passing through the lateral opening. A bushing is removably placed in said guide slot via said longitudinal direction in a planned fit, the bushing defining a throughbore aligned with the guide slot and adapted to receive the pin extending in said longitudinal direction when the bushing is in the guide slot for pin placement. | 03-12-2015 |
