Technical Field

Embodiments herein generally relate to systems for closing and healing wounds.

Background

Prior to embodiments of the disclosed invention, the retention suture assembly had holes perpendicular to the plane of the plate. Some such examples are shown in U.S. patent 4,210,148 to Stivala, U.S. patent 6,120,525 to Westcott, and U.S. patent 5,127,412 to Cosmetto. Among them, Stivala is most widely used, as shown in FIG. 1.

Fig. 1 shows a wound W located in the skin S. There is a first suture assembly 1, said first suture assembly 1 further comprising a first pad 2 joined to a first plate 3. First pad hole 4 is linearly aligned with first plate hole 5, and first suture assembly 1 further includes first pad 2 joined to first plate 3. There is a second suture assembly 6, said second suture assembly 6 further comprising a second pad 7 joined to a second plate 8. The second pad holes 9 are linearly aligned with the second plate holes 10. Suture 11 travels perpendicular to skin S through first pad hole 4, first plate hole 5, second plate hole 9, and second pad hole 10.

The suture 11 generates two sets of forces. The closing forces 12, 13 are shown pushing the first edge 14 of the wound W towards the second edge 15 of the wound W. The closing forces 12, 13 shown in the x-direction are advantageous. However, the tearing forces 16, 17 tear the suture 11 through the skin S, causing significant scarring. The tearing forces 16, 17 are shown in the positive y-direction, which is advantageous. Embodiments of the disclosed invention address this problem.

As used herein, "plate" means a material that does not significantly deform under a load of five pounds of force. In some embodiments, the plates may be made of autoclavable polypropylene plastic. As used herein, "pad" means a material that deforms significantly under a load of five pounds of force. This may include medical grade and FDA approved polyurethane foams. The terms "plate" and "pad" belong to the category of "retention bar" which can be a plate, a pad or any item functionally equivalent.

Turning to fig. 3 and 4, the retention suture assembly 310 is adapted to join the first edge 312 to the second edge 314. The retention suture 310 includes a first suture component 316 proximate the first edge 312. The first suture assembly 316 further includes a first retention rod 318, the first retention rod 318 further including a first retention rod outer perimeter 320, the first retention rod outer perimeter 320 defining a first retention rod upper plane 322 and a first retention rod lower plane 324.

The first retention bar upper opening 326 further includes a first retention bar upper opening center 328, the first retention bar upper opening center 328 being disposed within the outer perimeter on the first retention bar upper plane 322. The first retention bar lower opening 330 further includes a first retention bar lower opening center 332, the first retention bar lower opening center 332 disposed within the outer perimeter on the first retention bar lower plane 324. The first retention bar orthogonal axis 334 is orthogonal to the first retention bar upper plane 322 and the first retention bar lower plane 324 and travels through the first retention bar upper opening center 328. The first retention rod channel 330 engages the first retention rod upper opening 326 and the first retention rod lower opening 330 with a channel axis 336 running through the first retention rod upper opening center 328 and the first retention rod lower opening center 332. The first angle 85 is measured clockwise from the channel axis 336 to the first retention bar orthogonal axis 334. The first angle 85 is at least five degrees, but no greater than one hundred seventy-five degrees.

The retention suture 310 includes a second suture component 416 proximate the second edge 314. The second suture assembly 416 further includes a second retention rod 418, the second retention rod 418 further including a second retention rod outer perimeter 420, the second retention rod outer perimeter 420 defining a second retention rod upper plane 422 and a second retention rod lower plane 424.

Second retention bar upper opening 426 further includes a second retention bar upper opening center 428, the second retention bar upper opening center 428 disposed within an outer perimeter on second retention bar upper plane 422. Second retention bar lower opening 440 also includes a second retention bar lower opening center 442, which second retention bar lower opening center 442 is disposed within an outer perimeter on second retention bar lower plane 424. Second retention bar orthogonal axis 444 is orthogonal to second retention bar upper plane 422 and second retention bar lower plane 424 and travels through second retention bar upper opening center 428. Second retention rod channel 440 engages second retention rod upper opening 426 and second retention rod lower opening 440 with channel axis 446 traveling through second retention rod upper opening center 428 and second retention rod lower opening center 442.

The second angle 86 is measured counterclockwise from the channel axis 436 to the second retention bar orthogonal axis 434. The second angle 86 is at least five degrees, but no greater than one hundred seventy-five degrees. The suture 450 is placed through the first retention rod channel 330 and the second retention rod channel 430 and then tied into a knot 452 over the first edge 312 and the second edge 314.

Fig. 5 shows a potential theory why the present invention works well. The suture 194 passes through the first pad second channel 170 and the first plate channel 130, the first pad second channel 170 and the first plate channel 130 traveling toward the wound W (not shown). In fig. 1, the Stivala suture is distal to the wall of the channel. The present invention variously teaches that the suture 194 should be in contact with the first plate channel wall at a first connection point 196. Occasionally, this point coincides with the first pad orthogonal axis 134, but such centrality is not required. Suture 194 applies a horizontal occlusive force 198. However, the vertical tear force 200 is partially offset from the first pad 114 by a negative vertical force 202 acting in the negative y-direction.

Fig. 6 shows another arrangement of an embodiment of the present invention. Here, the first suture assembly 512 includes a first pad 514 adjacent to a first plate 516. The first pad 514 is defined by a first pad upper plane 518 and a first pad lower plane 520. The first upper planar pad 518 also includes a first upper planar opening 522 having a first upper planar opening center 524. Similarly, the first pad lower plane 520 also includes a first pad lower plane opening 526 having a first pad lower plane opening center 528. There is a first pad channel 530 between the first pad lower planar opening 126 and the first pad upper planar opening 122. The first cushion channel major axis 532 passes through the first cushion upper planar opening center 524 and the first cushion lower planar opening center 528. For reference, the first pad orthogonal axis 534 passes through a first pad upper plane opening center 524 that is orthogonal to the first pad upper plane 518 and the first pad lower plane 520. The first pad angle 87 is measured clockwise from the first pad orthogonal axis 534 to the first pad channel major axis 532.

First plate 516 is bounded by a first plate upper plane 538 and a first plate lower plane 540. The first plate upper planar surface 138 also includes a first plate upper planar opening 542 having a first plate upper planar opening center 544. Similarly, the first plate lower planar surface 540 further includes a first plate lower planar opening 546, the first plate lower planar opening 546 having a first plate lower planar opening center 548. There is a first plate channel 550 between the first plate lower planar opening 546 and the first plate upper planar opening 542. A first plate channel radius 552 passes through the first plate upper planar opening center 544 and the first plate lower planar opening center 548.

Comparing fig. 5 with fig. 6, the first plate channel radius 152 is much larger than the first plate channel radius 552. This causes the suture 594 to distribute an increasing amount of force into the sidewalls of the first pad channel 530. The distribution of the horizontal force 560 on the sidewalls of the first pad channel 530 is no higher than in fig. 7.

Fig. 7 shows another arrangement of an embodiment of the present invention. Here, the first suture assembly 612 includes a first pad 614 adjacent to a first plate 616. The first pad 614 is defined by a first pad upper plane 618 and a first pad lower plane 620. The first upper planar pad 618 also includes a first upper planar opening 622 having a first upper planar opening center 624. Similarly, the first pad lower plane 620 also includes a first pad lower plane opening 626 having a first pad lower plane opening center 628. There is a first pad channel 630 between the first pad lower planar opening 626 and the first pad upper planar opening 622. The first pad channel major axis 632 passes through the first pad upper planar opening center 624 and the first pad lower planar opening center 628. For reference, the first pad orthogonal axis 634 passes through a first pad lower plane opening center 628 that is orthogonal to the first pad upper plane 618 and the first pad lower plane 620. The first pad angle 88 is measured clockwise from the first pad orthogonal axis 534 to the first pad channel major axis 532.

First plate 616 is bounded by a first plate upper plane 638 and a first plate lower plane 640. The first plate upper plane 638 further includes a first plate upper plane opening 642 having a first plate upper plane opening center 644. Similarly, first plate lower planar surface 640 further comprises a first plate lower planar opening 646, the first plate lower planar opening 646 having a first plate lower planar opening center 648. There is a first plate channel 650 between the first plate lower planar opening 646 and the first plate upper planar opening 642. The first plate channel radius 652 passes through the first plate upper planar opening center 644 and the first plate lower planar opening center 648.

In this example, the first pad angle 88 is substantially larger than the first pad angle 87. This simply results in the forces being distributed differently within first suture assembly 612.
