RETRACTABLE SHAVER BUR

Abstract:

A shaver bur for resecting bone inside the joint in arthroscopic procedures. The shaver bur includes an inner assembly having an inner hub with an inner tube extending distally therefrom. The inner tube terminates in a distal bur tip. The shaver bur also includes an outer assembly having an outer hub with an outer tube extending distally therefrom. The inner tube is moveable within the outer tube between a retracted position and an extended position. The shaver bur additionally includes a deployment mechanism connected to the outer hub. The deployment mechanism is movable in a first direction and a second direction. Moving the deployment mechanism in the first direction moves the inner tube to the extended position and moving the deployment mechanism in the second direction moves the inner tube to the retracted position.
