摘要:
An inserter head (210) for an intervertebral disc implant is disclosed comprising: a body (212) having a leading end with a concave surface (214); said concave surface having an upper end and a lower end; a first pin (222) projecting from said concave surface adjacent said upper end of said concave surface; a pair of second pins (224A, 224B) spaced from one another and projecting from said concave surface adjacent said lower end of said concave surface; a wedge (220) projecting from said concave surface and being disposed between said first pin and said pair of second pins.
摘要:
Apparatus and methods for preparing a disc space and inserting an intervertebral disc implant therein are disclosed. Among the various instruments disclosed are a midline marker (1000), a reference pin drill and insertion guide (1060), a fin drill guide (1314), a chisel guide (1450), a sizer (1508), a serrated broach (1636), an implant dispenser (1756), and an implant insertion tool (1800). Methods of utilizing these tools are also disclosed.
摘要:
A kit for preparing an intervertebral disc space for receiving an implant (100) includes a plurality of trials (152) having different sizes. Each trial (152) includes a body (154) insert ible into an intervertebral disc space, the body (154) having a leading end (162), a trailing end (164), a top surface (156) and a bottom surface (160), the top surface of the body having a first groove (176) formed therein. Each implant also includes a flange (166) secured to the trailing end (164) of the body (154), the flange (166) having a first channel (180) aligned with the first groove (176), wherein each of the different sized trials has a different flange thickness. The flange thickness controls advancement of a cutting tool such as a chisel (192) into the first groove at the top surface of the trial body, which controls the depth of the cut into vertebral bone.

The device comprises anchoring means (3) in the form of an arrowhead or wedge applied at the free extremities of a tape (2) made of a synthetic macro-porous material or a prosthetic material replacing the facial tissue, where said anchoring means are fitted with gripping elements provided along the profile and on the surface in the form of projecting crests (4, 5, 7, 8) and pins (9) and a concavity (6) provided on each of the opposite faces to position the extremities of a forceps or other suitable instrument, while said cavities (6) are fitted with transversal gripping elements (13) and the anchoring means are optionally curved in their main plane.
摘要:
An instrumentation set may include insertion instruments for forming an implant between bone structures. The insertion instruments may include a spreader (400) and a separator (300). The bone structures may be vertebrae. Implant members (12) may be attached to the spreader and positioned between the bone structures. The separator may be inserted into the spreader to establish a desired separation distance between the implant members. Connectors (14) may be inserted into the implant members to join the implant members together and form the implant. The insertion instruments may be removed. A seater (1100) may be used to set the position of the connectors relative to the implant members to inhibit disassembly of the implant.
