Abstract

Disclosed is a system to engage one or more tools. In the system a drive shaft and collet may be assembled to engage and disengage, selectively, a plurality of tools. Further, a tracking device may be used to track a location of at least a portion of the tool.

First claim

What is claimed is:

1 . A trackable powered drill assembly, comprising:
a powered drill motor housing; a collet assembly adapted to operably couple to the powered drill motor housing; an attachment member including an internal surface defining a bore, the bore dimensioned to at least partially receive the collet assembly and form a first locking assembly; a second locking assembly operably engaged to at least one of the attachment member or the collet assembly, the second locking assembly axially movable between a first position allowing rotational movement of the attachment member relative to the collet assembly and at least one additional position preventing rotational movement of the attachment member relative to the collet assembly; a wave spring disposed on the collet assembly; a D-ring biased by the wave spring towards an indent defined in an external surface of the collet assembly; and a protrusion extending from an internal surface of the attachment member and configured to engage the D-ring, wherein the wave spring is further configured to bias the attachment member towards the indent by biasing the D-ring that engages the protrusion.

2 . The trackable powered drill assembly according to claim 1 , wherein the second locking assembly is configured to rotationally fix the attachment member to the collet assembly.

3 . The trackable powered drill assembly according to claim 1 , further comprising:
a tool having a tool tip extending from the attachment member.

4 . The trackable powered drill assembly according to claim 1 , wherein the second locking assembly includes:
a tab extending from an internal surface of the attachment member; and an indent formed in an external surface of a collet housing of the collet assembly, wherein at least a portion of the tab is configured to engage the indent.

5 . The trackable powered drill assembly according to claim 1 , wherein the second locking assembly includes a first portion disposed on the collet assembly, a second portion disposed on the attachment member, and a wedge, and
wherein:
the first portion includes a first groove formed in an external surface of a collet housing of the collet assembly,
the second portion includes a second groove formed in an internal surface of the attachment member,
the wedge is selectively moveable within the second groove relative to the collet housing and the first groove, and
the wedge is configured to engage between the internal surface of the attachment member and the external surface of the collet housing.

6 . The trackable powered drill assembly according to claim 1 , further comprising:
a tracking device engaged to an exterior surface of the powered drill motor housing and configured to allow navigation of the trackable powered drill assembly.

7 . The trackable powered drill assembly according to claim 6 , further comprising:
a tracking connector extending from the tracking device including an annular member having an internal surface, the internal surface configured to slide over and engage the external surface of the powered drill motor housing.

8 . The trackable powered drill assembly according to claim 6 , wherein the tracking device is fixed to the powered drill motor housing via friction-fit engagement.

9 . The trackable powered drill assembly according to claim 6 , further comprising:
a tracking device mount having a bore defined therethrough, the tracking device mount configured to operably secure to an exterior surface of the powered drill motor housing, the tracking device mount dimensioned to support a tracking device configured to allow navigation of the trackable powered drill assembly.

10 . The trackable powered drill assembly according to claim 5 , wherein the first portion of the second locking assembly is formed on the collet housing is a rotational locking seat and the second portion of the second locking assembly formed on the attachment member is a rotational locking member.

11 . A trackable powered drill assembly, comprising:
a powered drill motor housing; a collet assembly adapted to operably couple to the powered drill motor housing; an attachment member including an internal surface defining a bore, the bore dimensioned to at least partially receive the collet assembly and form a first locking assembly; a second locking assembly operably engaged to at least one of the attachment member or the collet assembly, the second locking assembly axially movable between a first position allowing rotational movement of the attachment member relative to the collet assembly and at least one additional position preventing rotational movement of the attachment member relative to the collet assembly, wherein the second locking assembly includes a first portion disposed on the collet assembly, a second portion disposed on the attachment member, and a wedge, and wherein:
the first portion includes a first groove formed in an external surface of a collet housing of the collet assembly,
the second portion includes a second groove formed in an internal surface of the attachment member,
the wedge is selectively moveable within the second groove relative to the collet housing and the first groove, and
the wedge is configured to engage between the internal surface of the attachment member and the external surface of the collet housing.

12 . The trackable powered drill assembly according to claim 11 , wherein the first portion of the second locking assembly is formed on the collet housing and is a rotational locking seat and the second portion of the second locking assembly is formed on the attachment member and is a rotational locking member.
