Instruments and methods for subperiosteal tunneling and related surgical procedures
The present invention is a group of surgical instruments with improved function and design for dental and craniofacial surgery, especially subperiosteal tunneling and related procedures. The instruments include surgical elevators for vestibular incision or incisions in the gingival sulcus. The instruments have varying angles and shapes to create a mucosal tunnel in any oral or maxillofacial region. The instrument suite also optionally includes specially designed forceps for introduction of graft material inside the subperiosteal tunnel and to assist with suturing of the graft to surrounding tissue.
1. A suite of surgical instruments for subperiosteal tunneling comprising:
a first elevator having a base portion comprised of a handle having an ergonomic grip, a first elongated shaft region, a second elongated shaft region and terminating in a distal curved and rectangular atraumatic tip;
a second elevator having an ergonomic grip, a first elongated shaft region, a second shaft region having a curved transitional portion and terminating in a distal curved atraumatic tip, wherein a combination of an angled portion of the first elongated shaft region and a second curved transitional portion and the second shaft region have positive values for at least two angles along the length of the second elevator such that the distal curved atraumatic tip is comprised of an arc region that disposes a most distal portion of the distal tip outside an axis of the first elongated shaft region; and
a third elevator having an ergonomic grip, and first, second, and third shaft regions having an angled portion therebetween such that the third shaft region has an angled portion relative to the first shaft region greater than 90° and less than 180°.
2. The suite of surgical instruments of claim 1 wherein the first, second, or third elevators is further comprised of a mating fixture.
3. The suite of surgical instruments of claim 1 wherein the first and second elongated shaft regions of the first elevator are oriented by angle having a range between 0° and 45°.
4. The suite of surgical instruments of claim 1 wherein at least a portion of any shaft region of the first, second, or third elevator is comprised of an anodized dark color for visualization through tissue.
5. The suite of surgical instruments claim 1 wherein the distal curved atraumatic tip of the first elevator is comprised of an arc region.
6. The suite of surgical instruments of claim 5 , wherein the arc region of either the first or the second elevator is contiguous with the second shaft region.
7. The suite of surgical instruments of claim 5 , wherein the arc region of the first or second elevator is between approximately one-eighth circle and approximately one-half circle.
8. The suite of surgical instruments of claim 1 wherein the third elevator is comprised of a distal atraumatic tip proximate to the third shaft region.
9. The suite of surgical instruments of claim 1 wherein the first and second shaft regions of the third elevator are disposed in a first plane and the third shaft region is disposed in a second plane.
10. The suite of surgical instruments of claim 1 , wherein the first shaft region of the third elevator is disposed in a first plane and the second and third shaft regions of the third elevator are disposed in a second plane.
