Adjustable microfracture handle
A microfracture device for creating small holes in a bone. The microfracture device includes a handle having a body extending along a central longitudinal axis with a proximal end and a distal end; a shaft connected to the distal end of the body, the shaft having a distal tip; wherein the distal tip extends at first angle relative to the central longitudinal axis; a sliding mechanism slidably engaged with a surface of the body and moveable between a first configuration and a second configuration; and wherein the sliding mechanism further comprises a striking surface extending therefrom, wherein the striking surface is positioned at a second angle to the central longitudinal axis that is at least substantially similar to the first angle.
1. A microfracture device, comprising:
a handle having a body extending along a central longitudinal axis with a proximal end and a distal end;
a shaft connected to the distal end of the body, the shaft having a distal tip;
wherein the distal tip extends at first angle relative to the central longitudinal axis;
a sliding mechanism slidably engaged with a surface of the body, the sliding mechanism fits over and partially around and is movable with respect to an outside surface of the shaft between a first configuration and a second configuration; and
wherein the sliding mechanism further comprises a striking surface extending therefrom, wherein the striking surface is positioned at a second angle to the central longitudinal axis that is at least substantially similar to the first angle.
2. The microfracture device of claim 1 , wherein the sliding mechanism also comprises an elongated portion extending proximally from the striking surface.
3. The microfracture device of claim 2 , wherein in the first configuration, a portion of the sliding mechanism is within the body of the handle and in the second configuration, a portion of the sliding mechanism is positioned over at least a portion of the shaft.
4. The microfracture device of claim 3 , further comprising a thumb rest positioned along the elongated portion, the thumb rest located proximally relative to the striking surface.
5. The microfracture device of claim 2 , wherein the striking surface is circular.
6. The microfracture device of claim 5 , further comprising a striking body extending from the striking surface, the striking body having a rectangular cross-section.

12. The microfracture device of claim 11 , wherein the distal tip extends at a 110° angle relative to the central longitudinal axis.
13. A microfracture device, comprising:
a handle having a body extending along a central longitudinal axis with a proximal end and a distal end;
a channel extending through the body from the proximal end to the distal end;
a cavity within the channel;
a sliding mechanism movable within the channel over the cavity between a first configuration and a second configuration;
a shaft extending between a proximal raised portion and a distal tip, the proximal raised portion removably connected within the cavity in the channel; and
wherein the sliding mechanism fits over and partially around and is moveable with respect to an outside surface of the shaft, and the distal tip extends at an angle relative to the central longitudinal axis.
14. The microfracture device of claim 13 , wherein the distal tip extends at an angle equal to or less than 90° relative to the central longitudinal axis.
