    摘要： A cutting instrument and method of use for preparing an osteochondral plug for implantation into a bone defect site. The instrument includes a dual function cutting block, a base holder, a rod mechanism and a trimming mechanism. The cutting block has a bore sized to receive the plug, at least one trimming channel and a transverse paring slot. The cutting block functions to hold the plug within the bore to allow for length and cross-sectional sizing. The base holder is constructed to fix the cutting block in a first orientation that allows the rod mechanism to position the plug within the cutting block for accurate length sizing. The base holder is also constructed to fix the cutting block in a second orientation which aligns the cutting block with the trimming mechanism so that an angled blade may engage the trimming channel and cut at least two sides of the plug.

    摘要： A surgical instrument and method are provided for positioning an osteochondral plug within a bone defect site. The instrument includes an elongate shaft, a ribbon, an elongate sleeve and a locking mechanism. The shaft has proximal and distal ends, with the distal end being shaped to contact the osteochondral plug. The ribbon extends along two sides of the shaft and around the distal end, forming a loop that is used to secure the osteochondral plug to the distal end. The sleeve is movably mounted to the shaft for reciprocating relative thereto between retracted and extended positions. The sleeve includes a slot that allows for visualization and cutting of the ribbon. The locking mechanism locks the ribbon in place and thereby controls the size and tension of the loop that surrounds the osteochondral plug, securing it to the distal end of the shaft.

    摘要： A dilator for adapted to implant a graft in a bone. The dilator includes a hollow frusto conical configuration having a distal and proximal end, a continuous tapered outer surface extending from said distal end to said proximal end of said dilator, the continuous tapered outer surface configured to engage a bone in order to radially expand the bone outwardly as the dilator is advanced into an opening, one end of dilator having a cross-section less than the cross-section of the opening for insertion into the opening, and the other end of the dilator having a cross-section greater than the cross-section of the opening so that insertion of the body member in the opening expands the opening.

    摘要： A surgical cutting attachment that may include an elongated first member with a proximal end and a distal end including a first blade and an elongated second member with a proximal end and a distal end including a second blade. The second member may be positioned in a side-by-side orientation with the first member and may be connected to the first member at a pivot. A first set of apertures may extend through the first member and a second set of apertures may extend through the second member. A connector may be positioned on the proximal end of at least one of the first and second members. The first and second members may be movable between a first orientation with the first set of apertures aligned with the second set of apertures and the first blade spaced away from the second blade, and a second orientation with the first and second sets of apertures spaced away from each other and the first blade in proximity to the second blade. The first and second blades may form a scissor mechanism and the first and second set of apertures may form a shear mechanism. Methods of using the surgical cutting attachment are also disclosed.
