Abstract

Abstract An apparatus for autogenous transplantation of articular cartilage with bone from one site, such as in the knee, to another to treat chondral defects. Graft harvesters and recipient site harvesters create identically-sized donor graft osteochondral cores and recipient sockets. Collared pins disposed within the harvesters facilitate removal of the harvested cores. Windows formed in the side of the harvester tubes allow visualization of the graft, such as when being inserted into the recipient socket. A removable three-piece driver/extractor is provided to allow for impact-driving and depth control of the harvesters at the selected sites.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 89 words
Apparatus for transplanting osteochondral cores in a joint, the apparatus comprising: a cutting tube having a sharp cutting edge on a distal end and a cannulated handle on a proximal end; and a pin having a distal end and a proximal end disposed slidably within the cutting tube, the pin having a collar, with a smooth distal surface, disposed on the distal end of the pin, and a handle on the proximal end of the pin, the handle being disposed slidably within the cannulated handle of the cutting tube.
Claim 2
Dependent Claim 23 words
The apparatus of claim 1, further comprising a lumen, and a window in a side of the cutting tube for visualizing the lumen.
Claim 3
Dependent Claim 14 words
The apparatus of claim 1 or 2, wherein the sharp cutting edge is smooth.
Claim 4
Independent Claim 16 words
The apparatus of any preceding claim, further comprising a driver removably secured to the cutting tube.
Claim 5
Independent Claim 134 words
An apparatus for transplanting osteochondral cores in a joint, the apparatus comprising: a core-cutting tube, having a sharp cutting edge on a distal end, a cannulated handle on a proximal end, and an inner diameter; a socket-cutting tube, having a sharp cutting edge on a distal end, a cannulated handle on a proximal end, and an outer diameter equal to the inner diameter of the core cutting tube; and a pin disposed slidably within each of the cutting tubes, each pin having a distal end and a proximal end, each pin having a collar with a smooth distal surface disposed on the distal end of the pin, and a handle disposed on the proximal end of the pin, the handle being disposed slidably within the cannulated handle of each of the cutting tubes, respectively.
