INTRA-OPERATIVE ACL GRAFT INSTRUMENTATION
A line lock system may include a line routed through a plate. The plate may have an elongated body with a plurality of passageways. The line is routed to form at least one one-way slide so no knots are required. The system may include filaments routed through the passageways of the plate or around a dogbone feature of the plate. The filaments may be used to toggle the plate after passage through a hole to prevent withdrawal of the plate back through the hole. The system may include a line lock stabilizer or counter-tension tool to stabilize the line lock as the line is adjusted, a compression limiter to selectively reduce compression in the one-way slide to facilitate adjustment of the line, means for adjusting the line, or a line cutter.
1 . A system comprising:
a line lock, wherein the line lock comprises a body at least partially bounding a plurality of passageways;
a line comprising a standing portion and a locking portion, wherein the line is routed through at least some of the passageways, wherein the locking portion comprises a constricted section and a compression section, wherein the compression section fixes the constricted section on the body;
a line lock stabilizer, wherein the line lock stabilizer stabilizes the line lock against a structure while the length of the standing portion is adjusted; and
a compression limiter, wherein the compression limiter releases the compression section to allow a length of the standing portion to be adjusted.
2 . The system of claim 1 , wherein the line lock stabilizer comprises a first surface, wherein the first surface contacts the line lock, wherein when the first surface contacts the line lock, the line lock is secured against the structure.
3 . The system of claim 3 , wherein the structure is selected from the group consisting of a bone, a tendon, a ligament, a muscle, a connective tissue, a graft, an implant, and a prosthesis.
4 . The system of claim 1 , wherein the compression limiter comprises an engaging feature, wherein the engaging feature connects the compression limiter to the compression section.
5 . The system of claim 4 , wherein when the engaging feature connects the compression limiter to the compression section, actuation of the compression limiter releases the compression section from the body.
6 . The system of claim 1 , comprising:
a means for adjusting the line, wherein the means for adjusting the line adjusts the length of the standing portion.
7 . The system of claim 6 , wherein the means for adjusting the line comprises a line-engaging feature, wherein the line-engaging feature connects the means for adjusting the line to the line.
8 . The system of claim 7 , wherein when the line-engaging feature is connected to the line, actuating the means for adjusting the line adjusts the length of the standing portion.
9 . The system of claim 7 , wherein the line-engaging feature connects the means for adjusting the line to a connection point on the line, wherein the means for adjusting the line pulls the line along the body to move the connection point a first distance from the body.
10 . The system of claim 9 , wherein the compression limiter releases the compression section by moving the compression section a second distance from the body.
11 . The system of claim 10 , wherein the first distance is larger than the second distance.
12 . A system comprising:
a line lock, wherein the line lock comprises a body at least partially bounding a plurality of passageways;
a line comprising a standing portion and a locking portion, wherein the line is routed through at least some of the passageways, wherein the locking portion comprises a constricted section and a compression section;
a line lock stabilizer, wherein the line lock stabilizer stabilizes the line lock against a surface while the length of the standing portion is adjusted; and
a means for adjusting the line, wherein the means for adjusting the line adjusts the length of the standing portion.
13 . The system of claim 12 , wherein the line lock stabilizer comprises a first surface, wherein the first surface contacts the line lock, wherein when the first surface contacts the line lock, the line lock is secured against the structure.
14 . The system of claim 13 , wherein the structure is selected from the group consisting of a bone, a tendon, a ligament, a muscle, a connective tissue, a graft, an implant, and a prosthesis.
15 . The system of claim 12 , comprising:
a compression limiter comprising an engaging feature, wherein the engaging feature connects the compression limiter to the compression section.
16 . The system of claim 15 , wherein when the engaging feature connects the compression limiter to the compression section, actuation of the compression limiter releases the compression section from the body.
17 . The system of claim 12 , wherein the means for adjusting the line comprises a line-engaging feature, wherein the line-engaging feature connects the means for adjusting the line to the line.
18 . The system of claim 17 , wherein when the line-engaging feature is connected to the line, actuating the means for adjusting the line adjusts the length of the standing portion.
19 . The system of claim 17 , wherein the line-engaging feature connects the means for adjusting the line to a connection point on the line, wherein the means for adjusting the line pulls the line along the body to move the connection point a first distance from the body.
20 . The system of claim 19 , comprising:
a compression limiter, wherein the compression limiter releases the compression section to allow a length of the standing portion to be adjusted, wherein the compression limiter releases the compression section by moving the compression section a second distance from the body.
21 . The system of claim 20 , wherein the first distance is larger than the second distance.
22 . A system comprising:
a line lock comprising a body at least partially bounding a plurality of passageways, a line comprising a standing portion and a locking portion, wherein the line is routed through at least some of the passageways, wherein the locking portion comprises a constricted section and a compression section, wherein the compression section fixes the constricted section on the body;
a line lock stabilizer, wherein the line lock stabilizer stabilizes the line lock against a structure while the length of the standing portion is adjusted; and
a cutter, wherein the cutter is actuatable to cut the line.
