Set Screw Driver
A tool for use with a fastener includes a drive shaft extending along a longitudinal axis from a proximal end to a distal end. The tool includes an engaging tip extending from the distal end, the engaging tip sized and shaped to detachably engage a receiving portion of the fastener, wherein the engaging tip is rotationally fixed to the fastener when the engaging tip is engaged with the fastener. The tool includes a compressible winged member extending distally from the drive shaft, the compressible winged member moveable between compressed and uncompressed positions. In the uncompressed position, the compressible winged member spans a distance greater than an internal diameter of a portion of the receiving portion.
1 . A tool for use with a fastener, the tool comprising:
a drive shaft extending along a longitudinal axis;
an engaging tip extending from the drive shaft, the engaging tip adapted to detachably engage a receiving portion of the fastener;
a compressible winged member having a proximal end and an open-ended distal end located farther from a handle of the tool than the proximal end, the compressible winged member movable between compressed and uncompressed positions, the compressible member engaged with the drive shaft such that an outer surface of the compressible winged member is engaged with the fastener when the engaging tip is engaged with the fastener.
2 . The tool of claim 1 , wherein the compressible winged member is compressed by the fastener when the engaging tip is engaged with the fastener.
3 . The tool of claim 1 , wherein the compressible winged member is biased radially outward to retain the fastener when the engaging tip is engaged with the fastener.
4 . The tool of claim 1 , wherein the engaging tip is rotationally fixed to the fastener when the engaging tip is engaged with the fastener.
5 . The tool of claim 1 , wherein the compressible winged member is configured to engage with the receiving portion when the engaging tip is engaged with the fastener.
6 . The tool of claim 1 , wherein the compressible winged member includes a first wing and a second wing connected by a base.
7 . The tool of claim 1 , wherein the compressible winged member is disposed within a slot defined by the engaging tip.
8 . The tool of claim 1 , wherein the compressible winged member includes a first wing disposed within a first slot of the engaging tip and a second wing disposed within a second slot of the engaging tip.
9 . A tool for use with a fastener, the tool comprising:
a drive shaft extending along a longitudinal axis;
an engaging tip extending from the drive shaft, the engaging tip adapted to detachably engage a receiving portion of the fastener;
a compressible winged member extending from a cavity defined by the drive shaft, the compressible winged member movable between compressed and uncompressed positions,
wherein the engaging tip includes a corrugated portion defining a plurality of ridges and grooves between each adjacent pair of ridges, the corrugated portion defining at least a portion of a slot adapted to receive the compressible winged member.
10 . The tool of claim 9 , wherein the engaging tip includes a proximal stem positioned within the drive shaft, the proximal stem defining at least a portion of the slot.
11 . The tool of claim 10 , wherein the engaging tip includes a circular base coupled to a distal end of the proximal stem, the circular base defining at least a portion of the slot.
12 . The tool of claim 11 , wherein the corrugated portion extends distally from the circular base.
13 . The tool of claim 9 , wherein the engaging tip includes a distal head extending distally from the corrugated portion and defining a circumference, the distal head defining at least a portion of the slot.
14 . The tool of claim 13 , wherein the compressible winged member includes a first wing protruding radially beyond the circumference of the distal head when in the uncompressed position, defining a first gap between the first compressible wing and a center portion of the distal head.
15 . The tool of claim 14 , wherein the first wing is biased toward the uncompressed configuration and is configured to be compressed radially inward to close the first gap and have an outer edge of the first wing align with the circumference of the distal head when in the compressed configuration.
16 . The tool of claim 14 , wherein the compressible winged member includes a second wing protruding radially beyond the circumference of the distal head when in the uncompressed configuration, defining a second gap between the second wing and the center portion of the distal head.
17 . The tool of claim 16 , wherein the second wing is biased in the uncompressed configuration and is configured to be compressed radially inward to close the second gap and have an outer edge of the second wing align with the circumference of the distal head when in the compressed position.
18 . The tool of claim 9 , wherein the engaging tip is rotationally fixed to the fastener when the engaging tip is engaged with the fastener.
19 . The tool of claim 9 , wherein the cavity extends along the longitudinal axis and is configured to receive a portion of the compressible winged member.
20 . A system comprising:
a fastener; and
a tool for use with the fastener, the tool comprising:
a drive shaft extending along a longitudinal axis;
an engaging tip extending from the drive shaft, the engaging tip sized and shaped to detachably engage a receiving portion of the fastener, wherein the engaging tip is rotationally fixed to the fastener when the engaging tip is engaged with the fastener;
a compressible winged member extending from the drive shaft, the compressible winged member movable between compressed and uncompressed positions,
wherein the compressible winged member includes a proximal connecting base with wings extending distally therefrom to a distal end, the distal end being farther away from a handle of the tool than the proximal connecting base, wherein the compressible winged member is configured to be compressed by engagement with the fastener.
