Abstract
In a surgical instrument for forming a flared region of a hole, a tool radially extends in response to the instrument engaging a surface of a hole in a substrate. The instrument can include a passage sized to receive a guide wire.
Claims24
A surgical instrument comprising:
- a body defining a passage sized to slidably receive a guide wire along an axis, at least a portion of the body being sized for insertion into a hole in a substrate;
- and
- a tool carried by the body and configured to perform shaping of the substrate when the tool is rotated to form a flared region therein;
- wherein the body comprises an actuator configured to move the tool between a first position located a first radial distance from the axis and a second position located a second radial distance, greater than the first radial distance, from the axis.

4 more elements
A surgical instrument comprising:
- a member having an axis and sized for at least partial insertion into a hole in a substrate;
- a tool carried by the member;
- and
- an actuator configured to move the tool between a first position located a first radial distance from the axis and a second position located a second radial distance, greater than the first radial distance, from the axis;
- the member having a surface configured to bear against a bottom surface of the hole and support the member while the actuator moves the tool from the first position to the second position.
2 more elements
A surgical instrument comprising:
- a member having an axis and sized for at least partial insertion into a hole in bone;
- a tool carried by the member;
- and
- an actuator configured to move the tool between a first position located a first radial distance from the axis and a second position located a second radial distance, greater than the first radial distance, from the axis in response to a surface of the member engaging the bottom surface of the hole;
- wherein the tool is sharp in a direction of rotation of the member to remove bone material to form a flared region in the bone.
