BONE ANCHOR INSERTION DEVICE

摘要

A bone anchor insertion device comprises a handle, a nosepiece connected to a distal end of the handle, a bone anchor connected to the nosepiece, and an actuator disposed on the handle for deploying the bone anchor, which suture is also fixed to a portion of soft tissue to be attached to a portion of bone. A suture ratchet or tensioning mechanism is disposed in the handle for tensioning suture which is associated with the bone anchor. This mechanism permits precise tensioning, while also permitting one-handed operation, thereby allowing the practitioner to use his or her other hand for other activities, such as camera operation or the like.

1. A bone anchor insertion device, comprising:
a handle assembly comprising;
a housing;a hand lever pivotally attached to the handle housing, the hand lever having a drive arm;a rack mechanism having at least two teeth operable to successively engage with the drive arm so as to move the rack mechanism as the hand lever is actuated; and at least one elongate sleeve extending from the distal end of the housing; and a pull tube coaxially disposed with the at least one elongate sleeve and coupled to the rack mechanism, a distal end of the pull tube selectively coupled to a bone anchor.
