摘要:
Systems and methods for a spinal surgical procedure are described. Specifically systems and methods for calculating global spinal alignment are described.
摘要:
A system and method for converting intraoperative 2D C-Arm images into a 3D representation of the position and orientation of surgical instruments relative to the patient's anatomy is provided.
摘要:
The present invention involves systems and methods for determining nerve proximity, nerve direction, and pathology relative to a surgical instrument based on an identified relationship between neuromuscular responses and the stimulation signal that caused the neuromuscular responses.
摘要:
This present subject disclosure provides a novel implant which is readily adjustable to provide a precise angle of lordosis. The implant may be positioned while in low profile, collapsed geometry, and may be expanded when in place to provide a precise angle of lordosis.
摘要:
A system (10) for performing somatosensory evoked potential monitoring during surgery comprises a stimulator (22) to deliver an electrical stimulation signal to a peripheral nerve, a sensor (24) to detect somatosensory responses evoked by the stimulation signal and a control unit (12) communicating with the stimulator and the sensor. The control unit is configured to direct transmission of the stimulation signal and receive the response data from the sensor. In addition, the control unit is configured to optimize signal parameters of the stimulation signal based on the response data, assess spinal cord health by identifying a relationship between the response to a first stimulation and to a second stimulation, the relationship being at least one of a change in latency and a change in amplitude between the first and second responses. The control unit is also configured to communicate the assessment to a user.
摘要:
A dynamic stabilization system including a dynamic rod with a first and second coupler assemblies, a pre-tensioned central cord and a flexible bumper, which are coupled to the bony structures of the spine by way of pedicle screws for use in spinal fixation surgery.
摘要:
A method and system (10) for discriminating tissue types, controlling the level of therapy to tissue, and determining the health of a known tissue by measuring the characteristics an electrical signal applied to conductive element located within or by the tissue.
