An arthroscopic anchor insertion tool and method for inserting consecutive, longitudinally aligned anchors from a common deployment channel of a cannulated needle by employing positive stops to prevent travel of an actuator from simultaneously advancing multiple anchors into a surgical site.
Claims15
An anchor insertion system comprising:
- a needle, the needle having a proximal end, a distal end, and a hollow shaft extending between the proximal and distal ends, the proximal end of the needle comprising a handle, the distal end of the needle comprising a needle tip assembly for housing at least two anchors;
- an actuator assembly for deploying at least one of the at least two anchors from the needle tip assembly, at least a portion of the actuator assembly slidably disposed within the needle;
- a cylindrical disk rotatably attached to the actuator assembly, a surface of the cylindrical disk comprising a hole for receiving a guide pin;
- a sleeve disposed around the cylindrical disk, a portion of a surface of the sleeve defining an angled slot therethrough;
- wherein the guide pin is configured to engage the angled slot;
- and
- wherein the angled slot defines first and second stops for preventing the actuator assembly from simultaneously deploying the at least two anchors into a surgical site.
