摘要:
Each of an osteochondral plug graft and a kit comprises a trapezoid shaped construct configured for osteochondral implanting. An osteochondral regeneration method comprises forming a recipient socket in a chondral area of an articular joint in need of repair; harvesting a trapezoid shaped graft from another chondral area; and implanting the trapezoid shaped graft into the recipient socket.
摘要:
An implantable tissue growth stimulator is disclosed. The implantable tissue growth stimulator includes electronic circuitry to alter the voltage output by the stimulator. The implantable tissue growth stimulator may be controlled from an external device via wireless communication. The implantable tissue growth stimulator may be configured for use with an implant. In particular, the implantable tissue growth stimulator may be incorporated into an orthopaedic device such as a hip prosthesis. The implantable tissue growth stimulator may be used to stimulate bone growth.
摘要:
A system and method are provided for monitoring the condition of the skeletal system and adjusting a treatment device to provide appropriate treatment in response to the sensed signal. More particularly, in one aspect the present invention is directed to a sensor for detecting changes at a spinal level and a dynamic treatment system adjustable in response to the detected changes.
摘要:
A surgical procedure for preparing a damaged area of a human knee to receive at least one graft, according to which a moldable material is positioned over the damaged area and removed after it hardens. The mold is used as a template to determine the number and/or a dimension of the openings to be formed in the damaged area for receiving corresponding grafts.
摘要:
A surgical instrument for implanting a prosthetic member. The instrument includes an orientation sensor that detects an initial orientation of the prosthetic member and an implanting orientation of the prosthetic member. The instrument further includes a memory module and an input device that receives a user input to transfer the initial orientation detected by the orientation sensor into the memory module for storage. Furthermore, the instrument includes an orientation feedback device that selectively provides an orientation feedback signal to a user. Moreover, the instrument includes a controller that causes the orientation feedback device to provide the orientation feedback signal when the implanting orientation detected by the orientation sensor is substantially equal to the initial orientation stored in the memory module.
摘要:
A surgical procedure for implanting tissue from a cadaver/autograft bone into a recipient site at an anatomical area of a patient, and a computer-readable medium encoded with a computer program for use in the surgical procedure.
摘要:
An apparatus and method for interrogating and automatically identifying a radio-frequency tagged surgical instrument tray and its contents of RFID-tagged surgical instruments are disclosed. The surgical instrument tray and its contents come into contact with an RF signal transmitted by the RFID reader, and as a result, the RFID tags affixed on the instrument tray and the surgical instruments respond by transmitting back to the RFID reader data pertaining to the history of the surgical instruments. A data terminal, which is connected to the RFID reader, may contain data pertaining to the radio frequency tagged surgical instruments during packaging, and during the return of the surgical instrument trays to the packager, identifies the surgical instruments.
摘要:
A training apparatus, model, system, and method are disclosed that allows any trainee to train to perform surgeries in areas of the human body that include one or more nerves. The training model is configured to mimic one or more areas of the human anatomy in which the procedure is going to be performed that contains nerves by providing a realistic anatomical model of the area of interest. A neural element is positioned in the anatomical area of interest that is configured to behave like a real nerve. A neural monitoring system is utilized to ensure that while using specially designed surgical tools or devices during the procedure, the surgeon is trained to avoid taking actions that would adversely affect the functionality of the nerves located in this area after the surgery.
摘要:
A chisel system for harvesting an implantable graft from an area of a human having a cartilage overlying a condyle, according to which a module is provided that has one end connected to a handle. A cutting surface is formed at the other end of the module that cuts through the cartilage and condyle.
摘要:
A system for detecting the integrity of a previously implanted prosthetic device may include a detector including a sensor configured to detect signals from the implant and securing means for securing the sensor in a sensing position relative to the implantable device. The system also may include a power source configured to provide power to the sensor and a computation means for processing data communicated by the detector and for displaying the processed data for diagnosing.
