Abstract
A cannulated retrograde reamer that is adjustable to create tunnels of multiple different diameters. The cannulated retrograde reamer substantially reduces the risk of tunnel malposition and/or misalignment, and can be adjusted to create a range of tunnel diameters, thereby allowing inventory levels to be reduced for a surgical case.
Claims25
A retrograde reamer for use in surgical procedures, comprising:
- a first tubular shaft;
- at least one second shaft movably disposable within the first tubular shaft;
- and
- at least one cutting member movably coupled to one of the first tubular shaft and the second shaft,
- wherein, in response to relative movement of the first tubular shaft and the second shaft, the cutting member is adapted to be displaced from a collapsed position to at least one deployed position, thereby defining at least one cutting diameter.
