Abstract

A power adapter includes an adapter shaft having a first end for coupling to a rotary tool and a second end configured to be coupled to a working tool. Additionally, the second end includes a slot. The power adapter also includes a locking mechanism operatively coupled to the second end of the adapter shaft. The locking mechanism includes a dowel pin movable between a first position and a second position within the slot.

First claim

I claim:

1 . A power adapter comprising:
an adapter shaft having a first end for coupling to a rotary tool and a second end configured to be coupled to a working tool, wherein the second end includes a slot; a sliding grip housing the adapter shaft, the sliding grip including an annular abutment and a counterbore at a distal end of the sliding grip that terminates at the annular abutment; and a locking mechanism operatively coupled to the second end of the adapter shaft, the locking mechanism including:
a dowel pin movable between a working tool engaging first position and a working tool releasing second position within the slot, and
a bushing disposed between the sliding grip and the adapter shaft and movable relative to the sliding grip and the adapter shaft,
wherein the sliding grip is movable between a distal position enabling the dowel pin to assume the first position, and a proximal position enabling the dowel pin to assume the second position.

2 . The power adapter of claim 1 , wherein the slot includes a longitudinal axis angled relative to a longitudinal axis of the adapter shaft.

3 . The power adapter of claim 1 , wherein the adapter shaft includes a counterbore about its second end coaxial with a longitudinal axis of the adapter shaft.

4 . The power adapter of claim 1 , wherein the adapter shaft includes a counterbore about its second end and wherein the slot is in fluid communication with the counterbore.

5 . The power adapter of claim 1 , wherein the sliding grip is movable relative to the adapter shaft.

6 . The power adapter of claim 1 , wherein the locking mechanism further comprises a biasing member biasing the bushing into contact with the dowel pin.

7 . The power adapter of claim 1 , wherein the locking mechanism further comprises a biasing member biasing the dowel pin distally towards the second end of the adapter shaft.

8 . The power adapter of claim 1 , wherein the annular abutment is configured to engage the bushing.

9 . The power adapter of claim 1 , wherein the annular abutment is adjacent the slot of the adapter shaft.

10 . The power adapter of claim 1 , wherein the first end is configured as a quick connection.

11 . A powered surgical tool comprising:
a rotary tool; the power adapter of claim 1 coupled to the rotary tool; and a working tool coupled to the power adapter.

12 . The powered surgical tool of claim 11 , wherein the working tool includes a connection end for coupling to the power adapter, wherein the connection end includes a groove for releasably receiving the dowel pin.

13 . A power adapter comprising:
an adapter shaft having a first end for coupling to a rotary tool and a second end configured to be coupled to a working tool, wherein the second end includes a slot having a longitudinal axis angled relative to a longitudinal axis of the adapter shaft; wherein the adapter shaft further includes a counterbore about its second end and wherein the slot is in fluid communication with the counterbore; a locking mechanism operatively coupled to the second end of the adapter shaft, the locking mechanism including:
a dowel pin movable between a working tool engaging first position and a working tool releasing second position within the slot;
a sliding grip configured to house the adapter shaft, the sliding grip including an annular abutment and a counterbore at a distal end of the sliding grip that terminates at the annular abutment, wherein the sliding grip is movable between a distal position enabling the dowel pin to assume the first position, and a proximal position enabling the dowel pin to assume the second position; and a bushing disposed between the sliding grip and the adapter shaft and movable relative to the sliding grip and the adapter shaft.
