First Claim
Patent Images
1. A device for manually implanting a bone anchor coupled to a suture into a bone, comprising:
- a handle including a proximal end and a distal end;
a shaft including a first end and a second end, said first end being connected to said distal end of said handle; and
a bone anchor mount for releasably engaging said bone anchor coupled to a suture, said bone anchor mount connected to said second end of said shaft and oriented toward said handle so that said bone anchor coupled to a suture may be implanted into the bone by manually applying a retrograde force to said bone anchor coupled to a suture;
wherein said bone anchor mount comprises;
an outer cylinder;
an inner cylinder rigidly connected to said outer cylinder and extending proximally therefrom; and
a tapered bone anchor receptacle for releasably engaging the bone anchor, said bone anchor receptacle rigidly connected to said inner cylinder and extending proximally therefrom.

8. A device for manually implanting a bone anchor coupled to a suture into a bone, comprising:
-
a handle including a proximal end and a distal end; a hook shaped shaft including a first end and a second end, said first end being connected to said distal end of said handle; a bone anchor mount for releasably engaging said bone anchor coupled to a suture, said bone anchor mount connected to said second end of said shaft and oriented toward said handle so that said bone anchor coupled to a suture may be implanted into the bone by manually applying a retrograde force, wherein the longitudinal axis of said bone anchor mount is aligned with the longitudinal axis of said handle, said bone anchor mount comprising outer cylinder including a cavity and an annular shoulder, and a tapered bone anchor receptacle for releasably engaging the bone anchor; and a protective sheath connected to said bone anchor mount for isolating said bone anchor from contact with tissue prior to implantation of said bone anchor into the bone, said protective sheath comprising; a first telescoping cylinder including a proximal end, a distal end and a lumen extending therethrough, a first shoulder at said distal end of said first telescoping cylinder and a second shoulder at said proximal end of said first telescoping cylinder; a second telescoping cylinder including a proximal end, a distal end and a lumen extending therethrough, a first shoulder at said distal end of said second telescoping cylinder and a second shoulder at said proximal end of said second telescoping cylinder; and a spring, wherein said first shoulder of said first telescoping cylinder engages said shoulder of said outer cylinder, said second shoulder of said first telescoping cylinder engages said first shoulder of said second telescoping cylinder, and said spring is disposed between said second shoulder of said second telescoping cylinder and said outer cylinder, whereby said first and second telescoping cylinders are movable between a first position in which they are extended from said outer cylinder to cover said bone anchor and a second position in which they are retracted in said cavity of said outer cylinder to expose said bone anchor.
