Abstract: A distractor for separating adjacent elements, such as vertebrae. The distractor preferably has a scissors-type distracting mechanism, either in a simple scissors or double-acting scissors configuration. A set of blades is provided on each jaw such that an implant may be inserted between the spaced apart blades. The set of blades includes at least two blades.

Abstract: The present invention includes a portable power supply having a housing that encloses a battery. Booster cables protrude from the housing and are electrically connected to the battery. Electrical clamps are attached to the booster cables and may connect to electrical terminals. The housing may include a clamp anchor integral thereto. The clamp anchor may include an anchor base and an anchor finger, wherein the anchor finger is generally perpendicular to the anchor base. The electrical clamp may be secured on the clamp anchor. The present invention further includes a booster cable with an electrical clamp that has a clamp cover rotatably mounted on the electrical clamp. The clamp cover may cover some of the electrically conductive portions of the electrical clamp and/or provide additional positioning of the electrical clamp on the clamp anchor.

Abstract: An instrument may be used to move a rod attached to vertebrae to an opening of a fixation device. Positioning the rod in the opening may properly align the vertebrae with respect to the vertebra attached to the fixation element. A fixation holder may be coupled to the fixation element. The holder may include a protrusion. The protrusion may engage a guide of the instrument during use. The protrusion and the guide may ensure that the rod is properly positioned within the opening in the connector. The instrument and holder may automatically align the rod to the opening without requiring manual manipulation of the rod or the fixation element. The fixation element may include a connector. The connector may be positioned within the fixation element so that removal of the connector from the fixation element is inhibited.

Abstract: A distractor for separating adjacent elements, such as vertebrae. The distractor preferably has a scissors-type distracting mechanism, either in a simple scissors or double-acting scissors configuration. The distractor includes blades that are removable from the jaws of the distractor such that different blades may be used depending on the patient and situation with which the distractor is to be used. The jaws include a mating fixture and the blades include a mating portion for removable association with the mating fixture.

Abstract: A retraction apparatus and method for separating human tissue during surgical procedures is described for use. The retraction apparatus may include two elongated members, a first end having two protrusions located on the first end and on the mid-shaft, a second end having grips, a retainer, and a fastener. The retraction apparatus includes protrusions for coupling to human tissue. The retraction apparatus includes grips that enable separation of the first ends of the elongated members when the second ends are brought together. The grips may be attached to the retainer, located at the second end, for fixing the position of the first ends. Locking the retraction apparatus into a fixed position consists of engaging a fastener attached to the grips to the retainer such that the first ends substantially resist any force to move or disengage from human tissue.

Abstract: A distractor for separating adjacent elements, such as vertebrae. The distractor preferably has a scissors-type distracting mechanism, either in a simple scissors or double-acting scissors configuration. Additionally, one or more of the blades, distracting mechanism, and handles are offset with respect to the other to facilitate visualization and to increase the space available for an implant holder. The blades are configured to enhance versatility of the distractor. In a first embodiment, the blades are removable from the jaws of the distractor such that different blades may be used depending on the patient and situation with which the distractor is to be used. In a second embodiment, curved portions are provided between the blades and jaws such that the blades are offset from the jaws in a smooth transition which does not expose sharp edges to internal organs or vasculature of the patient.

Abstract: An inter-vertebral implant having of a frame-like cage (1) enclosing a space (20), with a top and bottom surface (11,12), two side surfaces (13, 14), a front (16) and a rear wall (15). The top and bottom surfaces (11, 12) have a plurality of perforations (24), the total area of which amounts to 40 to 55% of the total area of said surfaces (11, 12). The individual area of a single perforation (24) is at most 20% of the total area of the top and bottom surfaces (11, 12). The ratio VH/VK between the volume VH of the space (20) and the total volume VK of the cage (1) is in the range from 70 to 90%. The cage (1) is substantially wedge-shaped with top and bottom surfaces (11, 12) diverging towards the front wall (16). This gives the advantage that, owing to the large bone bearing area of the top and bottom surfaces, the implant is prevented from sinking into the end plates of the body of the vertebra.
