Microfracture pick
A microfracture pick having features configured to aid a user in advancing the microfracture pick through bone. The microfracture pick has an elongated member with a proximal end, a distal end, a sharp, optionally angled tip disposed adjacent the distal end of the elongated member, and at least one engaging feature disposed at one or more locations on the elongated member for engaging a complementary feature of a strike instrument. By striking an impact surface of the strike instrument, the user can produce a force that is translated via the elongated member of the microfracture pick through the tip, thereby making penetration of the tip through the bone more effective.
1. A system for use in performing a microfracture procedure, comprising:
a strike instrument including a first elongated member having a proximal end, a distal end, and a hole in the first elongated member near its distal end, a strike pin configured to pass through the hole in the first elongated member, and an impact surface located at one end of the strike pin; and
a surgical device including a second elongated member having a distal end, an engaging feature located on the second elongated member, and a tip disposed adjacent the distal end of the second elongated member,
wherein the strike instrument further includes a complementary feature located at another end of the strike pin,
wherein the engaging feature of the surgical device is operative to engage the complementary feature of the strike instrument, and
wherein the first elongated member is configured to be disposed generally parallel to a longitudinal axis of the surgical device to allow engagement of the engaging feature with the complementary feature,
whereby, upon striking the impact surface of the strike instrument, a three is produced that is translated via the second elongated member through the tip.
2. The system of claim 1 wherein the first elongated member is configured to be at least temporarily fixated to the surgical device.
3. The system of claim 1 wherein the engaging feature of the surgical device is configured as a female connector, and the complementary feature of the strike instrument is configured as a male connector.
4. The system of claim 1 wherein the engaging feature of the surgical device is configured as a male connector, and the complementary feature of the strike instrument is configured as a female connector.
