Abstract
A driven fastener guide for guiding a fastener into a hole of a bone plate. The driven fastener guide includes an elongated driver configured for connecting to a drill and a fastener guide member operably connected to the elongated driver. The fastener guide member includes a split body and a through-bore configured for receiving the fastener. The fastener guide member is configured for aligning the fastener relative to the hole of the bone plate.

A driven fastener guide for guiding a fastener into a hole of a bone plate, comprising:
- an elongated driver configured for connecting to a drill;
- a fastener guide member operably connected to the elongated driver, the fastener guide member comprising a split body and a through-bore configured for receiving the fastener, the fastener guide member being configured for aligning the fastener relative to the hole of the bone plate;
- a housing;
- and
- a plurality of gears housed within the housing and configured for being driven by the elongated driver, wherein the plurality of ears comprises an input gear fixedly connected to the elongated driver, an output gear, and a pair of intermediary gears connected in between the input gear and the output gear, wherein the pair of intermediary ears are configured for reversing direction of rotation such that the input gear and the output gear can rotate in opposite directions.
A driven fastener guide for guiding a fastener into a hole of a bone plate, comprising:
- an elongated driver configured for connecting to a drill;
- a fastener guide member operably connected to the elongated driver, the fastener guide member comprising a split body and a through-bore configured for receiving the fastener, the fastener guide member being configured for aligning the fastener relative to the hole of the bone plate, wherein the split bod comprises a first portion having a first end, a second portion having a second end, and a connecting member connecting the first portion and the second portion together such that the first portion and the second portion are flexible relative to one another, wherein the first end and the second end are configured for engaging the bone plate to align the fastener relative to the hole of the bone plate;
- and
- a flexible spacer connected to the fastener guide member and extending in between the first portion and the second portion, the flexible spacer being configured for temporarily preventing the first portion and the second portion from collapsing to facilitate initially engaging the first end and the second end with the hole of the bone plate and for inwardly flexing upon engaging with the hole of the bone plate such that the first portion and the second portion can collapse to facilitate subsequently disengaging the first end and the second end from the hole of the bone plate.
A method for securing bone portions of an individual, comprising:
- providing or obtaining a bone plate and a driven fastener guide configured for guiding a fastener into a hole of the bone plate, the driven fastener guide comprising an elongated driver configured for connecting to a drill and a fastener guide member operably connected to the elongated driver, the fastener guide member comprising a split body and a through-bore with the fastener received therein and aligned relative to the hole of the bone plate via a threaded connection between the fastener guide member and the hole of the bone plate;
- and
- rotating the elongated driver in a first rotational direction to thereby simultaneously cause via said rotating:
- (i) the fastener to rotate in the first rotational direction to screw the fastener into the hole of the bone plate;
- and (ii) the fastener guide member to rotate in a second rotational direction opposite the first rotational direction to unscrew the fastener guide member from the hole of the bone plate.
