METHOD AND APPARATUS FOR RE-ATTACHING THE LABRUM TO THE ACETABULUM, INCLUDING THE PROVISION AND USE OF A NOVEL SUTURE ANCHOR SYSTEM

摘要

Apparatus for securing an object to bone, the apparatus comprising:
an anchor assembly comprising an anchor and an actuation element extending from the anchor, wherein applying a force to the actuation element when the anchor is disposed in a hole formed in a bone secures the anchor to the bone; andan inserter for deploying the anchor assembly in a hole formed in a bone, the inserter comprising:
a shaft for releasably engaging the anchor; anda force delivery mechanism mounted to the shaft and connected to the actuation element, the force delivery mechanism being constructed so as to receive an input force from an external source and to selectively apply an output force to the actuation element, with the force delivery mechanism being constructed so that the magnitude of the output force is limited regardless of the magnitude of the input force.

1. An inserter for deploying an anchor assembly in bone, wherein the anchor assembly comprises an anchor and an actuation element extending from the anchor, and further wherein deploying the anchor assembly in bone comprises positioning the anchor assembly in a hole formed in the bone and applying a force to the actuation element so as to secure the anchor to the bone, the inserter comprising:
a shaft for releasably engaging the anchor; and a force delivery mechanism mounted to the shaft and connected to the actuation element, the force delivery mechanism being constructed so as to receive an input force from an external source and to selectively apply an output force to the actuation element, with the force delivery mechanism being constructed so that the magnitude of the output force is limited regardless of the magnitude of the input force.
