International Classification:

G08B 13/14

US Classification:

3405728, 3405721, 3405731, 600300, 235375

Abstract:

An implantable orthopaedic component includes an information storage device that contains information related to the component. In the preferred embodiment, the information storage device is an RFID tag that is embedded within the component or within a housing that is configured to be removably engaged to the component. The RFID tag can be pre-loaded with information related only to the implant, or can be configured to allow additional surgery or patient specific information to be added by the caregiver at the time and point of surgery.

US Classification:

Abstract:

A telemetric tibial tray includes a lower plate that defines a plurality of cylindrical transducer cavities having circular load diaphragms. An upper plate is attached to the lower plate through support posts projecting from the load diaphragms. The support posts have a circular cross-section and a diameter of about 5. 0 mm. The lower plate further defines wiring channels communicating between the transducer cavities and a central cavity housing the circuit board for the telemetric tray. The wiring channels are arranged at a 45 degree angle relative to the sagittal plane of the knee joint in order to reduce the effects of the wiring channel intersection on the strain sensitivity of the tray. Each transducer cavity includes a radial strain gage array with four pairs of radially aligned strain gages, each pair aligned at a 45 degree angle relative to the sagittal plane of the knee joint. Each pair of strain gages includes an inner gage positioned at the point of maximum positive micro-strain across the diaphragm when loaded, and an outer gage positioned at the point of maximum negative micro-strain, to thereby increase the differential strain measured by the gages and increase the strain sensitivity of the tibial tray.

Assignee:

DePuy Products, Inc. - Warsaw IN

International Classification:

A61B 17/58

US Classification:

606 88

Abstract:

An apparatus for use in performing an orthopaedic surgical procedure on a patient includes at least one femoral paddle and a tibial paddle. At least one of the femoral paddle and the tibial paddle is movable away from the other. The apparatus also includes a sensor configured to generate a signal indicative of a force applied to the femoral paddle or the tibial paddle. The apparatus may be communicatively coupled to a computer assisted orthopaedic surgery system.

International Classification:

G01C 3/08

US Classification:

436 2, 73587, 73589, 7386123, 264407, 264411

Abstract:

A system and method for determining the operating state of a curable composition utilizes an acoustic wave or signal transmitted into a container holding the composition. In one embodiment, characteristics of a reflected component of the acoustic signal are measured and correlated to pre-determined values indicative of one or more operating states, or degrees of curing, of the composition. In another embodiment, characteristics of a transmitted component of the acoustic signal are measured and correlated. The characteristics include, for example, the speed of sound through the curable composition or the attenuation of the acoustic signal reflected by or transmitted through the composition.

Abstract:

A system, apparatus, and method for determining a position of an orthopaedic prosthesis includes a patient support platform, a sensor array coupled to the patient support platform, and a controller electrically coupled to the sensor array. The sensor array is configured to generate data signals in response to an output signal of a signal source(s) coupled to the orthopaedic prosthesis and/or a bone of the patient. The controller is configured to determine a position of the orthopaedic prosthesis and/or the bone of the patient based on the data signals.

International Classification:

A61B 5/05

US Classification:

600407, 600427

Abstract:

A registration pointer includes a camera located in an elongated shaft having a distal end configured to be contacted to a bone of a patient to register the bone to a computer assisted orthopaedic surgery system. The camera may be a hemispherical camera and may include a panoramic camera and a wide-angle camera equipped with a fish-eye lens. The registration pointer is configured to transmit images received by the cameras to the computer assisted orthopaedic surgery system for display thereon. The computer assisted orthopaedic surgery system may be configured to generate an image, such as a hemispherical image, based on the images received from the registration pointer.
