Quick release handle assembly

Claim 2

Handle assembly for retaining a tool, comprising: (a) a first member defining a bore for receiving the tool and a channel disposed at an angle to and communicating with the bore; (b) a pin member disposed within the channel and movable from a first locked position extending at least partially into the bore and a second unlocked position; (c) a movable collar slidable over the first member; (d) means for biasing the collar to retain the pin in communication with the bore; (e) a slide lever adapted to slide the sleeve; and (f) a pivot pin interconnecting the lever and the first member whereby the lever moves between a position adjacent and a position away from the first member.

Claim 3

A tool for reaming a bone canal, comprising: a first member having distal and proximal ends; a post extending from the proximal end of the first member, said post having a substantially D-shaped cross-section defining a substantially flat side with a notch therein; and a quick release handle having, a post-receiving member defining a bore for receiving said post and a channel disposed at an acute angle to and communicating with the bore, a pin member disposed within the channel and moveable from a first locked position extending at least partially into the bore and into said notch when the post is received in said bore and a second unlocked position, and means for retaining the pin member in said first position such that the post received in the bore is retained thereby.

Claim 4

A tool for reaming a bone canal, comprising: a first member having distal and proximal ends; a post extending from the proximal end of the first member, said post having a substantially D-shaped cross-section defining a substantially flat side with a notch therein; and a quick release handle having, a post-receiving member defining a bore for receiving said post and a channel disposed at an acute angle to and communicating with the bore, a pin member disposed within the channel and moveable from a first locked position extending at least partially into the bore and into said notch when the post is received in said bore and a second unlocked position, and means for retaining the pin member in said first position such that the post received in the bore is retained thereby.

Claim 5

Handle assembly for retaining a tool, comprising: first member defining a bore for receiving and orienting the tool with the handle and a channel disposed at an angle to and communicating with the bore; pin member disposed within the channel and movable from a first locked position extending at least partially into the bore and a second unlocked position; means for retaining the pin member in said first position such that the tool received in the bore is retained thereby, wherein said means for retaining the pin member comprises a movable collar slidable over the first member and biasing means for biasing the collar to retain the pin in communication with the bore: means for releasing the pin from said first position comprising a movable sleeve adapted to move the collar against the biasing means to release the pin; and a lever means to move the sleeve, the lever means comprises a slide lever adapted to slide the sleeve and a pivot pin interconnecting the lever and the first member whereby the lever moves between a position adjacent and a position away from the first member.

Claim 6

Handle assembly for retaining a tool, comprising: first member defining a bore for receiving and orienting the tool with the handle and a channel disposed at an angle to and communicating with the bore; pin member disposed within the channel and movable from a first locked position extending at least partially into the bore and a second unlocked position; means for retaining the pin member in said first position such that the tool received in the bore is retained thereby, wherein said means for retaining the pin member comprises a movable collar slidable over the first member and biasing means for biasing the collar to retain the pin in communication with the bore: means for releasing the pin from said first position comprising a movable sleeve adapted to move the collar against the biasing means to release the pin; and a lever means to move the sleeve, the lever means comprises a slide lever adapted to slide the sleeve and a pivot pin interconnecting the lever and the first member whereby the lever moves between a position adjacent and a position away from the first member.

Claim 7

A handle comprising an elongate body portion and a post-retaining portion; the retaining portion comprising: (a) a core member having a front and back end with a longitudinal bore formed in the front end and a channel in communication with said bore and formed in said core member at an acute angle to the bore; (b) a pin movable within the channel between a locked position wherein said pin protrudes and is retained within said bore and a released position wherein the pin is free to move within said channel; (c) a movable collar adapted to slide over said core member to move said pin within said channel and retain said pin in said locked position; (d) a spring mounted over the core and configured to bias the collar toward the front end of the core and to move said collar against said pin in said locked position; (e) a movable sleeve mounted over the collar and adapted to retract said collar to free the pin within the channel; (f) a slide lever adapted to slide said sleeve to thereby move said collar toward the rear end of the core; and (g) pivot means interconnecting the lever and the body portion whereby the lever is free to move between a locked position adjacent and an unlocked position away from the body position.

Claim 8

A handle comprising an elongate body portion and a post-retaining portion; the retaining portion comprising: (a) a core member having a front and back end with a longitudinal bore formed in the front end and a channel in communication with said bore and formed in said core member at an acute angle to the bore; (b) a pin movable within the channel between a locked position wherein said pin protrudes and is retained within said bore and a released position wherein the pin is free to move within said channel; (c) a movable collar adapted to slide over said core member to move said pin within said channel and retain said pin in said locked position; (d) a spring mounted over the core and configured to bias the collar toward the front end of the core and to move said collar against said pin in said locked position; (e) a movable sleeve mounted over the collar and adapted to retract said collar to free the pin within the channel; (f) a slide lever adapted to slide said sleeve to thereby move said collar toward the rear end of the core; and (g) pivot means interconnecting the lever and the body portion whereby the lever is free to move between a locked position adjacent and an unlocked position away from the body position.

Claim 9

The handle of claim 4 wherein the channel is at 30° to the bore.

Claim 10

The handle of claim 4 wherein said bore has a substantially D-shaped cross-section defining a substantially flat side.

Claim 11

The handle of claim 6 wherein said channel communicates with the substantially flat side of the D-shaped bore.
