Abstract
A clip to inter-connect primary and secondary bone zones having edges, comprising in combination a first tab to extend over a surface of the secondary bone zone, above a level defined by that surface; a first projection carried by the tab and configured to penetrate the primary bone zone at the edge thereof, and below the first level; and an auxiliary tab associated with the first tab positioned to extend over a top surface of the primary bone zone to guide movement of the clip as the first projection penetrates the primary bone zone.
Claims33
A clip to interconnect primary and secondary bone zones having edges, comprising in combination:
- a) a first tab to extend over a surface of the secondary bone zone, above a first level defined by that surface,
- b) a first projection carried by the tab and configured to penetrate the primary bone zone at the edge thereof, and below said first level,
- c) and an auxiliary tab associated with the first tab to be positioned to extend over a top surface of the primary bone zone to guide movement of the clip as the first projection penetrates the primary bone zone.
The method of using a clip to interconnect primary and secondary bone zones having edges, the clip comprising
- a) a first tab to extend over a surface of the secondary bone zone, above a first level defined by that surface,
- b) a first projection carried by the tab and configured to penetrate the primary bone zone at the edge thereof, and below said first level,
- c) and an auxiliary tab associated with the first tab and positioned to extend over a top surface of the primary bone zone to guide movement of the clip as the first projection penetrates the primary bone zone,
- i) causing the first projection to penetrate said primary bone zone,
- ii) and then locating the first tab to extend over said surface of the secondary bone zone, and causing the auxiliary tab to guidingly engage and slide on the top surface of the primary bone zone during said penetration, and attaching the first tab to said surface.
A cranial clip comprising, in combination
- a) a clip having a support plate, and an auxiliary plate carried by the support plate,
- b) a flange integral with the plate and extending away from the plate,
- c) at least one push-in tang integral with and protruding from the flange and extending generally parallel to the plate,
- d) said tang having a sharp tip to be pushed into cranial soft bone tissue proximate an edge of the skull,
- e) and a slide guide on the clip to slidably engage a cranial surface as the sharp tip is pushed into cranial tissue.
A cranial clip comprising, in combination
- a) a clip having a support plate, and an auxiliary plate carried by the support plate,
- b) a flange integral with the plate and extending away from the plate,
- c) at least one push-in tang integral with and protruding from the flange and extending generally parallel to the plate,
- d) said tang having a sharp tip to be pushed into cranial soft bone tissue proximate an edge of the skull,
- e) and a slide guide on the clip to slidably engage a cranial surface as the sharp tip is pushed into cranial tissue,
- f) including an installation tool interfitting the clip support plate and flange, for forwardly pushing and guiding the clip, as the tang penetrates said soft bone tissue.
A clip to interconnect primary and secondary bone zones having edges, comprising in combination:
- a) a first tab to extend over a surface of the secondary bone zone, above a first level defined by that surface,
- b) a first projection carried by the tab and configured to penetrate the primary bone zone at the edge thereof, and below said first level,
- c) and an auxiliary tab associated with the first tab to be positioned to extend over a top surface of the primary bone zone to guide movement of the clip as the first projection penetrates the primary bone zone,
- d) and wherein said auxiliary tab has a foldable portion proximate an extension of the tab associated with the projection.
A clip to interconnect primary and secondary bone zones having edges, comprising in combination:
- a) a first tab to extend over a surface of the secondary bone zone, above a first level defined by that surface,
- b) a first projection carried by the tab and configured to penetrate the primary bone zone at the edge thereof, and below said first level,
- c) and an auxiliary tab associated with the first tab to be positioned to extend over a top surface of the primary bone zone to guide movement of the clip as the first projection penetrates the primary bone zone,
- d) and including a retention strip fitting over the first tab and extending between legs defined by the auxiliary tab, in a folded position thereof.
