Abstract
A surgical device according to an exemplary aspect of the present disclosure includes, among other things, a tube and a cutting blade movable between a first position in which the cutting blade is concealed inside the tube and a second position in which the cutting blade is exposed through a sidewall of the tube.
Claims21
A surgical device, comprising:
- a tube;
- a cutting blade movable between a first position in which said cutting blade is concealed inside said tube and a second position in which said cutting blade is exposed through a sidewall of said tube;
- a clutch assembly configured to rotate to move said cutting blade between said first position and said second position;
- and
- a deflection pin configured to deflect said cutting blade radially outward of said tube as a tapered edge of said cutting blade is moved into contact with said deflection pin.
2 more elements
An expandable reamer, comprising:
- a tube;
- at least one cutting blade configured to incrementally advance to a cutting position radially outward from said tube to create a socket in bone;
- and
- a clutch assembly mounted to said tube and configured to move said at least one cutting blade in response to rotational movement of a portion of said clutch assembly, said clutch assembly including a clutch hub and a threaded hub, wherein teeth of one of said threaded hub and said clutch hub are removably received within recesses of the other of said threaded hub and said clutch hub, and wherein a distance between said teeth corresponds to a specific radially outward incremental advancement of said at least one cutting blade.
1 more element
A surgical device, comprising:
- a tube;
- a shaft surrounded by said tube;
- a cutting blade mounted to said shaft and movable between a first position in which said cutting blade is concealed inside said tube and a second position in which said cutting blade is exposed through a sidewall of said tube;
- a clutch assembly configured to move said cutting blade between said first position and said second position, said clutch assembly including a clutch hub and a threaded hub, and wherein rotational movement of a portion of said clutch assembly causes linear movement of said tube or said shaft;
- and
- a deflection pin configured to deflect said cutting blade radially outward of said tube as a tapered edge of said cutting blade is moved into contact with said deflection pin.
