Abstract
An orthopedic instrument having a quarter-turn disconnect apparatus. A female socket is provided on a broach or cutting instrument and a male plug with a locking mechanism is provided on a cutting apparatus. The male plug is inserted into the socket and pushed forward slightly against the resistance of a spring. The plug or socket are then turned one-quarter turn at which point the locking mechanism falls into place.
Claims22
A surgical apparatus comprising
- means for manipulating the apparatus,
- means for affecting the body of a patient, and
- means for selectively connecting said manipulating means and said body affecting means, said manipulating means and said body affecting means being connected to said connecting means and said connecting means comprising
- plug means having
- a shaft connected to one of said manipulating means and said body affecting means, said shaft having at least one radially extending tab on a distal end thereof, said tab having an axial length and
- a sleeve slidingly mounted on said shaft, said sleeve having at least one axially extending tab on a distal end thereof, means for preventing rotation of said sleeve relative to said shaft and
- socket means connected to the other of said manipulating means and said body affecting means, said socket means having
- a proximal cavity for receiving said distal end of said shaft, said cavity having an axial depth, and
- at least one internal tab extending radially inwardly within said proximal cavity at a proximal end thereof and having an axial length less than said axial depth of said proximal cavity, said radially extending tab of said shaft being configured to seat axially beyond said internal tab and said axially extending tab of said sleeve being adapted to fit adjacent said internal tab and forming a means for inhibiting relative rotation of said plug means with respect to said socket means.

An apparatus for connecting two surgical devices, said apparatus comprising
- plug means having
- a shaft for connection to one surgical device, said shaft having at least one radially extending tab on a distal end thereof, said tab having an axial length and
- a sleeve slidingly mounted on said shaft, said sleeve having at least one axially extending tab on a distal end thereof, means for preventing rotation of said sleeve relative to said shaft and
- socket means for connection to another surgical device, said socket means having
- a proximal cavity for receiving said distal end of said shaft, said cavity having an axial depth, and
- at least one internal tab extending radially inwardly within said proximal cavity at a proximal end thereof and having an axial length less than said axial depth of said proximal cavity, said radially extending tab of said shaft being configured to seat axially beyond said internal tab and said axially extending tab of said sleeve being adapted to fit adjacent said internal tab and forming a means for inhibiting relative rotation of said plug means with respect to said socket means.
