Abstract
A surgical procedure for preparing a graft for insertion in an opening in a human body, according to which a mold is formed in the opening and transferred from the opening to a position adjacent a stylus. A contour of the mold is traced with the stylus; and the tracing movement of the stylus is transferred to corresponding movement of a cutting member so that the cutting member cuts the same contour in the graft.
Claims15
A surgical procedure for preparing a harvested graft for implantation in an opening in a human body, the procedure comprising:
- forming a mold in the opening;
- transferring the mold from the opening to a position adjacent a stylus;
- tracing a contour of the mold with the stylus;
- providing the harvested graft having a size and shape that generally corresponds to the opening;
- and
- transferring the tracing movement of the stylus to corresponding movement of a cutting member so that the cutting member cuts the same contour in the graft, wherein the cut graft precisely fits the opening.
A surgical procedure for preparing a harvested graft for implantation in a defect, the procedure comprising:
- scanning the defect region;
- forming a model of the defect;
- placing the model into a copy mill;
- manually manipulating a stylus to trace tracing a contour of the model mold with a stylus in the copy mill;
- providing the harvested graft having a size and shape that generally corresponds to the opening;
- and
- transferring the tracing movement of the stylus to corresponding movement of a cutting member so that the cutting member cuts the same contour in the graft, wherein the cut graft precisely fits the opening.
