Abstract

A bone joint inserter device for accessing and manipulating a facet joint is provided. The bone joint inserter device improves surgical control in bone anchor location, placement, and insertion into target bone, while the inserter device also improves efficiency in engaging the target bone joint. The surgical instrument provides improved control of cutting device location and orientation, including directional control for precise bone anchor component insertion. Methods to use the bone joint inserter device in surgical procedures are also provided.

Dependent claims

A system comprising a bone joint inserter device comprising:

(a) a proximal section comprising an inserter head, wherein said inserter head comprises:
(i) a face, wherein said face is configured to engage a bone surface;
(ii) at least one prong, wherein said at least one prong is configured to engage a bone joint by sliding the at least one prong into the bone joint until the face engages the corresponding bone surface or other material near the bone joint;
(iii) a first channel comprising a first entry port and a first exit port, wherein said first entry port is at least as wide as said first exit port, and wherein said first channel is oriented at an acute angle relative to a center line of said inserter head;
and
(iv) a second channel comprising a second entry port and a second exit port, wherein said second entry port is at least as wide as said second exit port, and wherein said second channel is oriented at an acute angle relative to the center line of said inserter head;
wherein said first channel and said second channel are laterally oriented at opposite angles relative to the center line of said inserter head;
(b) a distal section comprising a notch operably receiving and positively orienting a drill, a cutting tool, a stylet, or a tamp;
(c) a shaft disposed between said proximal section and said distal section;
and
(d) a lumen extending along a central axis of the inserter device from said distal section through said shaft and through said proximal section.

A system comprising a bone joint inserter device comprising:

(a) a proximal section comprising an inserter head, wherein said inserter head comprises:
(i) a superior portion comprising a face, wherein said face is configured to engage a bone surface;
(ii) an inferior portion comprising at least one prong, wherein said at least one prong is configured to engage a bone joint by sliding the at least one prong into the bone joint until the face engages the corresponding bone surface or other material near the bone joint;
(iii) a first channel comprising a first entry port and a first exit port, wherein said first entry port is at least as wide as said first exit port, and wherein said first channel is oriented at an acute angle relative to a center line of said inserter head;
and
(iv) a second channel comprising a second entry port and a second exit port, wherein said second entry port is at least as wide as said second exit port, and wherein said second channel is oriented at an acute angle relative to the center line of said inserter head;
wherein said first channel and said second channel are laterally oriented at opposite angles relative to the center line of said inserter head;
(b) a distal section comprising a notch operably receiving and positively orienting a drill, a cutting tool, a stylet, or a tamp;
(c) a shaft disposed between said proximal section and said distal section;
and
(d) a lumen extending along a central axis of the inserter device from said distal section through said shaft and through said proximal section.
