Abstract
A kit including a guiding system and a bone material removal device, including an arcuate element, a guiding element configured to be attached to the arcuate element, a cannula, slidably insertable into a portion of the arcuate element, a cannulated bone material removal device having a longitudinal shaft, which is axially displaceable within the cannula.
Claims24
A kit including a guiding system and a bone material removal device, comprising:
- a guiding cannula;
- and
- a bone material removal device axially displaceable within said cannula, said bone material removal device comprising a longitudinal shaft having distal and proximal ends, and
- a cutting portion comprising a radially extendable cutting tooth selectively positionable in an open and closed orientations, said tooth having a longitudinally-oriented cutting edge and is pivotably attached to a hinge member longitudinally oriented along said longitudinal shaft, said radial extension causes an increase of a cross-sectional diameter of said cutting portion of the said bone material removal device.

A kit including a guiding system and a bone material removal device, comprising:
- a guiding cannula sized and fitted to receive said bone removal device;
- a connecting member comprising a tunnel, wherein said guiding
- cannula is slideable in a longitudinal direction within said connecting member tunnel;
- a guide arm having a base end and a terminal structure end, and attachable to said connecting member at said base end, wherein said terminal structure is located at or at least partially surrounding a region along said longitudinal direction when said guide arm and said connecting member are attached.
26-28. (canceled)
A method of drilling a bone tunnel in a bone comprising:
- positioning a guiding cannula on the bone;
- inserting a bone material removal device into said cannula;
- forming a bone tunnel in the anterograde direction through the bone while advancing said bone material removal device;
- extending an extendable cutting tooth of said bone material removal device to assume an open position;
- and
- expanding the bone tunnel in the retrograde direction while withdrawing said bone material removal device;
- wherein said bone material removal device rotates in a first direction when advancing and rotates in an opposite direction when withdrawing said bone material removal device.
