    摘要: The present application discloses embodiments of a surgical instrument to monitor a surgical site within a patient. In one embodiment, the instrument includes an elongated extender including a distal end and a proximal end. A body may be attached to the distal end of the extender. A plurality of light elements may be permanently attached to the body. The light elements may be spaced around the body and form a perimeter to provide dispersed light to the surgical site. An optical input member may be permanently attached to the body. The optical input member may include a distal end that faces outward away from the extender and towards the surgical site.

    摘要: An expandable vertebral replacement device and method of using the same is disclosed that allows surgeons to support two adjacent vertebrae after an intermediate vertebra or a portion of an intermediate vertebra has been removed for the spine. The expandable vertebral replacement device includes a first replacement body, a second replacement body and a collar. The second replacement body includes a projecting portion that is telescopically received within an axial passage defined by the first replacement body. The collar is used to force the collet of the first replacement body into clamping engagement with the projecting portion of the second replacement body to lock the expandable vertebral replacement device at a select height.

    摘要: The application is directed to implants and methods of spacing vertebral members. The implants include a body sized to fit within the desired space. One or more relief cuts are formed within the body and may include a variety of sizes, and shapes. Resorbable material is positioned within the relief cuts. The resorbable material includes an initial stiffness to give the implant a first rigidity when initially inserted into the patient. Over time, the resorbable material is absorbed causing the stiffness to decrease thereby lessening the rigidity of the implant. In general, the implant includes a maximum rigidity when the implant is initially inserted within the patient, and a minimum rigidity after the resorbable material is absorbed within the patient.

    摘要: Apparatus and methods are disclosed for use within an image-guided surgical navigation system for the storage and measurement of trajectories for surgical instruments. An icon representing the real-time trajectory of a tracked instrument is overlaid on one or more pre-acquired images of the patient. At the surgeon's command, the navigation system can store multiple trajectories of the instrument and create a static icon representing each saved trajectory for display. The surgeon may also measure a planar angle between any two trajectories. The angle is computed in the plane of the image, and therefore will be computed separately for each image displayed. Furthermore, the surgeon has the option of computing and displaying the three-dimensional distance between two points defined by any two trajectories.
