Surgical tools and methods for their use
Surgical tools and kits for performing methods include a grommet with cylindrical shaft, cutting tip, annular flange with suture retaining anchoring fixture; a grommet jig for extending between adjacent grommets and guiding a needle therebetween; a family of needles with single and double pointed ends, reinforced eyelets, stops to limit inadvertent exiting, double shaft construction with a longitudinal gap and sharpened, slicing ends, including a “J” shape embodiment; a bone anchor with ring to secure sutures about a patient's clavicle; a tissue dissector having radially extending cones to nick taut connecting tissues; a tissue rasp having a series of crisscrossing grooves along an end; a tissue mesher comprising one or more blocks having a matrix of holes for clamping a plurality of needles and a supporting framework; and a kit device and a method of surgically inserting an internal mesh brassiere under the breast skin.
1. A double-pointed needle comprising:
an elongated body having a double J shape having a first end region, a second end region, and a central more linear region disposed between the first and second end regions;
the first end region of the elongated body forming a curved shape relative to the central region wherein the curved shape includes a sharp elongated cutting tip with a pointed end forming a blade to cut tissue along a curve and not upwardly to stay level and in a same plane throughout the curve;
the second end region of the elongated body forming a curved shape relative to the central region wherein the curved shape of the second end region includes a sharp elongated cutting tip with a pointed end forming a blade to cut tissue along the curve and not upwardly to stay level and in the same plane throughout the curve; and
an opening within the second end region for receiving a thread maintained in the same plane along the curve, the opening extending entirely transversely through the elongated body and at a fixed position through the elongated body and spaced from the central region, the opening being closer to the pointed end of the first region than to a midpoint of the needle.
2. The needle of claim 1 , wherein the central region is straight.
3. The needle of claim 1 , wherein the central region has a circular cross-section.
4. The needle of claim 1 , wherein the opening disposed in the second end region includes a metal sleeve oriented around the opening.
5. The needle of claim 1 , wherein the opening disposed in the second end region comprises a cross section that is different than a cross section of the central region.
6. The needle of claim 1 , wherein the opening disposed in the second end region is formed of a non-linear passageway configured to hook a suture.
7. The needle of claim 1 , wherein the opening disposed in the second end region includes a deflectable arm that, in a deflected state, forms a slot in a perimeter of the opening to allow a suture to pass through the slot and into the opening, and, in a non-deflected state, closes the slot to form a continuous perimeter of the opening.
8. The needle of claim 1 , further comprising a second opening located at the first end region or the central region.
9. The needle of claim 1 , wherein at least one of the first end region and the second end region includes at least one of a graduation mark, a groove, or a ring to indicate a depth of needle penetration.
10. The needle of claim 1 , wherein the curved shape of the first end region has a first curvature that is different than a second curvature of the curved shape of the second end region.
11. The needle of claim 1 , wherein the central region is curved in the same plane as the first and second end regions.
12. The needle of claim 1 , wherein the opening is configured to be swaged such that the thread is secured in place.
13. The needle of claim 1 , wherein the elongated body is 20-50 centimeters in length.
14. The needle of claim 1 , wherein the elongated body has a diameter in the range of 1.5 to 3.5 millimeters.
15. The needle of claim 1 , wherein at least a portion of the first end region is wider than the central region.
16. The needle of claim 1 , wherein the cutting tip of the first end region and the cutting tip of the second end region have the same shape.
17. The needle of claim 1 , wherein the cutting tip of the second end region comprises a cross section and only two cutting edges, the cross section having a long axis and a short axis, the long axis extending along the same plane as the curved shape of the second end region, the short axis being oriented perpendicular to the plane of the curved shape of the second end region, and the two cutting edges being disposed on opposite ends of the long axis and extending along the same plane as the curved shape of the second end region.
