Description

Technical Field

[0001] This utility model relates to the field of stoma positioning ruler technology, specifically a stoma positioning ruler. Background Technology

[0002] Preoperative stoma localization can effectively reduce the incidence of postoperative enterostomy complications. The World Association of Ostomy Therapists recommends that stoma localization be completed preoperatively for both elective and non-elective surgeries, and has proposed the triangular stoma localization method, which achieves a better stoma position than traditional methods. The triangular stoma localization method is as follows: Figure 1 As shown, a triangle is formed by connecting the umbilicus, pubic symphysis, and anterior superior iliac spine. Each of the three points is connected to the midpoint of the opposite side, and the three lines intersect at a single point, which is the centroid of the triangle. This point is the pre-planned location for the stoma. Currently, in clinical practice, a ruler and pen are used to connect the three points, and the centroid is found after connecting the three points to the midpoint of the opposite side line. This method is relatively complicated and inconvenient for locating the stoma.

[0003] To facilitate the positioning of stomas, a stoma positioning ruler has become an urgent problem to be solved by the whole society. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a stoma positioning ruler, including a first positioning ruler, a second positioning ruler and a third positioning ruler;

[0005] The second positioning ruler is installed below the side end of the first positioning ruler, and a first positioning device is provided at the connection between the first positioning ruler and the second positioning ruler.

[0006] The third positioning ruler is installed above the side end of the first positioning ruler, and a second positioning device is provided at the connection between the first positioning ruler and the third positioning ruler.

[0007] A stoma mold is slidably connected to the second positioning ruler, and an indicator needle is rotatably connected to the third positioning ruler.

[0008] Furthermore, the first positioning device and the second positioning device have the same structure. The first positioning device includes a positioning threaded rod and a fixing nut. A first elliptical hole is provided at both ends of the first positioning ruler, and a second elliptical hole is provided on the second positioning ruler. The positioning threaded rod passes through the first elliptical hole and the second elliptical hole, and the first positioning ruler and the second positioning ruler are fastened together by the fixing nut.

[0009] Furthermore, the third positioning ruler is provided with a third elliptical hole.

[0010] Furthermore, the first positioning ruler has a first scale line evenly distributed on it, the second positioning ruler has a second scale line evenly distributed on it, and the third positioning ruler has a third scale line evenly distributed on it.

[0011] The advantages of the utility model compared to the prior art are:

[0012] This invention employs multiple structures, including a first positioning ruler, a second positioning ruler, a third positioning ruler, a stoma mold, and an indicator needle. By adjusting the end of the third positioning ruler, the first positioning device, and the second positioning device, they are aligned with the umbilicus, the pubic symphysis, and the anterior superior iliac spine, respectively. The stoma mold on the second positioning ruler is then adjusted until it reaches the center of gravity of these three points. This structure overcomes the inconvenience of using a pen and ruler for positioning in existing technologies, thus improving the efficiency of stoma positioning.

[0013] This invention installs a second positioning ruler below the side of the first positioning ruler and a third positioning ruler above the side of the first positioning ruler. By loosening the fixing nut and rotating the second and third positioning rulers to make them coincide with the first positioning ruler, the above structure can fold and store the stoma positioning ruler, solving the problem of the large space occupied and inconvenient storage of the triangular stoma positioning ruler in the prior art.

[0027] The specific operation process of this utility model is as follows:

[0028] (1) First, prepare the above-mentioned stoma ruler before the operation. When positioning the stoma, the positioning ring 10 on the outside of the second positioning ruler 2 can be aligned with the patient's umbilicus.

[0029] (2) Loosen the fixing nut 7 in the second positioning device, move the positioning threaded rod 6 in the second positioning device along the second elliptical hole 2-1 on the second positioning ruler 2 to the pubic symphysis point, and tighten the fixing nut 7 on the positioning threaded rod 6 in the second positioning device to lock its position.

[0030] (3) Loosen the fixing nut 7 in the first positioning device. After loosening, the first positioning ruler 1 can be rotated, or the positioning threaded rod 6 in the middle of the first positioning device can be moved. By adjusting the angle and position of the positioning threaded rod 6 in the first positioning device as described above, it can be made to coincide with the anterior superior iliac crest. Tightening the fixing nut 7 on the positioning threaded rod 6 of the first positioning device can achieve locking and positioning.

[0031] (4) Rotate the second positioning ruler 2 so that the end of the second positioning ruler 2 is adjusted to the midpoint between the umbilicus and the pubic symphysis. At this time, the indicator needle 5 can be rotated so that the end of the indicator needle is at the midpoint between the pubic symphysis and the anterior superior iliac spine. At this time, the intersection of the indicator needle 5 and the second positioning ruler 2 is the center of gravity of the three points of the umbilicus, the pubic symphysis and the anterior superior iliac spine. This is the location for stoma positioning. The stoma mold 4 on the second positioning ruler 2 can be moved to the stoma positioning position to achieve positioning.

[0032] After the stoma positioning ruler is used, the fixing nut 7 can be loosened, and the second positioning ruler 2, the third positioning ruler 3 and the first positioning ruler 1 can be folded and stored.
