1. A bone anchor insertion device, comprising:
- a handle;
a nosepiece connected to a distal end of said handle;
a bone anchor connected to said nosepiece;
an actuator disposed on said handle for deploying said bone anchor; and
a suture tensioning mechanism disposed in said handle for tensioning suture which is associated with said bone anchor, comprising a suture knob and a suture ratchet wheel, wherein said suture knob is rotatable to rotate said suture ratchet wheel.

Abstract
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.

5. A bone anchor insertion device, comprising:
-
a handle;
a nosepiece connected to a distal end of said handle, said nosepiece comprising an outer tube having a suture opening formed in its distal end and an inner tube disposed coaxially within said outer tube, said inner tube including a longitudinal opening therein, said inner tube being fixed relative to the outer tube;
a pull tube insertable into said inner tube;
a bone anchor disposed on said pull tube, said bone anchor including a laterally deployable member for engaging adjacent bone matter to secure said bone anchor in said bone matter; and
an actuator disposed in said handle for pulling said pull tube proximally to deploy the laterally deployable member of said bone anchor by engaging said laterally deployable member with a distal end surface of said inner tube. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
