Methods for forming a tunnel in bone
An orthopedic tool includes a main body and a reference member. The reference member may be configured to engage an anatomical feature of a patient, such as the patient's bone. The angle of the reference member may be adjusted using a knob.
1 . A method of forming a tunnel in tissue, comprising:
providing an orthopedic tool, wherein the orthopedic tool comprises:
a main body;
a drill guide having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end, the drill guide configured to engage the main body;
a reference member having a distal end, the reference member configured to engage the main body, and the reference member comprising an engagement component on the distal end, the engagement component configured to engage a patient's tissue; and
introducing the reference member to a surgical site such that the reference member engages the patient's tissue;
engaging the drill guide with a plurality of spring-loaded caps configured to engage a threaded portion of the drill guide and a ball plunger configured to engage the drill guide to lock the drill guide with respect to the main body of the orthopedic tool; and
advancing a drill pin through the lumen of the drill guide such that a tunnel is formed in the patient's tissue.
2 . The method of claim 1 , further comprising, with a reference member knob, adjusting a position of the reference member relative to the main body.
3 . The method of claim 1 , further comprising advancing a suture through the drill guide and the tunnel.
4 . The method of claim 1 , further comprising forcing a drill bit on the distal end of the drill guide into the patient's tissue, the drill bit having a circular cross-section.
5 . The method of claim 1 , wherein positioning the plurality of spring-loaded caps and the ball plunger such that the drill guide is locked in place with respect to the main body comprises rotating the drill guide such that a plurality of grooves of the drill guide engages at least one of the plurality of spring-loaded caps and the ball plunger.
6 . An orthopedic tool, comprising:
a main body;
a drill guide having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end, the drill guide configured to engage the main body;
a plurality of spring-loaded caps configured to engage a threaded portion of the drill guide and a ball plunger configured to engage the drill guide to lock the drill guide with respect to the main body; and
a reference member having a distal end, the reference member configured to engage the main body, and the reference member comprising an engagement component on the distal end.
7 . The orthopedic tool of claim 6 , further comprising a reference member knob configured to engage the main body and the reference member, the reference member knob configured to adjust a position of the reference member relative to the main body.
8 . The orthopedic tool of claim 7 , wherein the reference member knob is configured to adjust an angle of the reference member relative to the drill guide.
9 . The orthopedic tool of claim 6 , wherein the engagement component comprises curved components extending laterally from the distal end of the reference member.
10 . The orthopedic tool of claim 6 , further comprising a drill bit having a circular cross-section on a distal end of the drill guide.
11 . The orthopedic tool of claim 6 , wherein the reference member comprises a first arm configured to engage the main body, a second arm configured to engage a patient's tissue, and an angle between the first arm and the second arm.
12 . The orthopedic tool of claim 6 , wherein the engagement component comprises a fork component.
13 . A method of forming a tunnel in tissue, comprising:
providing an orthopedic tool, wherein the orthopedic tool comprises:
a main body;
a drill guide having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end, the drill guide configured to engage the main body;
a reference member having a distal end, the reference member configured to engage the main body, and the reference member comprising an engagement component on the distal end, the engagement component configured to engage a patient's tissue; and
introducing the reference member to a surgical site such that the reference member engages the patient's tissue;
engaging the drill guide with a plurality of spring-loaded caps configured to engage a thread portion of the drill guide and a ball plunger configured to engage the drill guide to lock the drill guide with respect to the main body of the orthopedic tool; and
advancing a drill pin through the lumen of the drill guide such that a tunnel is formed in the patient's tissue.
14 . The method of claim 13 , further comprising, using a reference member knob, adjusting a position of the reference member relative to the main body.
15 . The method of claim 13 , further comprising advancing a suture through the drill guide and the tunnel.
16 . The method of claim 13 , further comprising forcing a drill bit on the distal end of the drill guide into the patient's tissue, the drill bit having a circular cross-section.
17 . The method of claim 13 , wherein positioning the plurality of spring-loaded caps and the ball plunger such that the drill guide is locked in place with respect to the main body comprises rotating the drill guide such that a plurality of grooves of the drill guide engages at least one of the plurality of spring-loaded caps and the ball plunger.
