Description

Technical Field

[0001] This utility model relates to the field of stoma positioning, and in particular to a measuring and positioning device for a surgical abdominal stoma. Background Technology

[0002] An ostomy is an artificial opening made in the abdominal wall by a surgeon to treat certain intestinal diseases. Preoperative ostomy positioning can effectively reduce the incidence of postoperative enterostomy complications. One method of ostomy positioning is the triangular positioning method. The triangular ostomy positioning method is to draw a triangle 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. The three lines intersect at one point, which is the centroid of the triangle. This point is the preoperative ostomy location.

[0003] A search revealed that Chinese Patent Publication No. CN217186123U discloses a stoma positioning measuring ruler, including a first scale, a second scale, and a third scale. The surfaces of the first scale, the second scale, and the third scale are all provided with rectangular movable holes. There are three rectangular movable holes. The interior of every two rectangular movable holes is movably connected to the same first threaded post. One end of the first threaded post is fixedly connected to a circular plate, and the other end of the first threaded post is threadedly connected to a first threaded cap. The surface of the third scale is movably connected to a movable shell.

[0004] The aforementioned patent facilitates the adjustment of the device and the determination of the center position of the umbilicus, phalangeal symphysis, and anterior superior iliac spine. By loosening the rotating plate, the rotating plate drives the third threaded column to rotate, moving the third threaded column away from the locking rod and moving the fixed shell to the center position, which facilitates the determination of the stoma position. However, after determining the triangle point of the umbilicus, phalangeal symphysis, and anterior superior iliac spine, the aforementioned patent cannot directly obtain the line connecting the three vertices of the triangle to the midpoint of the opposite side, making it inconvenient to find the surgical stoma position that coincides with the centroid of the triangle, thus reducing the convenience of stoma positioning. Therefore, a measurement and positioning device for surgical abdominal stoma is proposed to solve the above problems. Utility Model Content

[0030] Reference Figure 1 , Figure 2The present invention provides an embodiment of a measuring and positioning device for a surgical abdominal stoma, comprising a first ruler 1 and a second ruler 2, which can rotate relative to each other to adapt to measurement requirements at different angles. A first stud 3 is fixedly connected to the top of the first ruler 1, and the second ruler 2 is rotatably mounted on the surface of the first stud 3. A first nut 4 is threadedly connected to the top of the first stud 3. The first nut 4 is used to fix the relative position of the first stud 3 and the second ruler 2 to prevent accidental rotation during measurement.

[0031] Reference Figure 2 , Figure 3 The surfaces of the first ruler 1 and the second ruler 2 are both provided with sliding grooves 5 that cooperate with the second stud 14. The top of the first ruler 1 and the top of the second ruler 2 are both fixedly connected with scale lines 6 for measurement and positioning. When moving the card block 9, the scale lines 6 are used for precise measurement and positioning to improve the accuracy of operation. A positioning mechanism is provided between the first ruler 1 and the second ruler 2.

[0032] Reference Figure 1 , Figure 3 The positioning mechanism includes a connecting block 7 and a connecting rod 8. The connecting rod 8 is slidably installed on the inner wall of the connecting block 7. When the locking block 9 moves in the locking groove 10, the overall length of the connecting block 7 and the connecting rod 8 will change accordingly. The number of connecting blocks 7 and connecting rods 8 is set to two sets. The connecting rod 8 is set to a Z shape. The end of the connecting rod 8 away from the connecting block 7 is fixedly connected to a locking block 9, which is set to a cylinder. The locking block 9 is located on the extension line of the center line of the connecting block 7.

[0033] Reference Figure 1 , Figure 3 The first ruler 1 and the second ruler 2 each have a groove 10 that cooperates with the locking block 9 on their adjacent sides. The locking block 9 is movably installed inside the groove 10 and can move inside the groove 10. The connecting block 7 has a sleeve 11 inside, and the sleeve 11 has a through hole 12 for passing a marking pen. The upper and lower sides of the sleeve 11 are fixedly connected with rings that serve as limiters. The surface of the rings fits against the surface of the connecting block 7 so that the sleeve 11 will not fall out of the groove 13. The connecting block 7 has a groove 13 that cooperates with the sleeve 11. The sleeve 11 is movably installed inside the groove 13 and can move inside the groove 13.

[0034] Reference Figure 1 , Figure 3The end of the connecting block 7 away from the connecting rod 8 is fixedly connected to a second stud 14. The number of second studs 14 is set to two. The second studs 14 are movably installed inside the slide groove 5. The cross section of the second stud 14 is set to I-shape. The top of the second stud 14 is threadedly connected to a second nut 15. The second nut 15 is used to fix the position of the second stud 14 on the first ruler 1 and the second ruler 2 to prevent displacement during the measurement process.

[0035] Working principle: In use, first clean the patient's abdominal skin to ensure there is no dirt, grease or other impurities. Then assemble the measuring and positioning device and check its stability and accuracy. Next, gently attach the measuring and positioning device to the patient's abdomen, ensuring it fits tightly against the patient's skin. Adjust the relative angle and position of the first scale 1 and the second scale 2, and slide the second stud 14 in the groove 5 so that the first stud 3 and the two second studs 14 correspond to the patient's umbilicus, phalangeal symphysis and anterior superior iliac spine, respectively. After adjusting the position, tighten the first nut 4 and the second nut 15 to fix the relative position of the first scale 1 and the second scale 2, and determine the center position of the umbilicus, phalangeal symphysis and anterior superior iliac spine.

[0036] Then adjust the relative position of the locking block 9 and the locking groove 10 so that the locking block 9 is located in the middle of the first stud 3 and the second stud 14, and at the midpoint of the line connecting the first stud 3 and the second stud 14. When moving the locking block 9, use the scale line 6 for precise measurement and positioning to improve the accuracy of the operation. When the locking block 9 moves in the locking groove 10, the connecting rod 8 will slide in the connecting block 7, and the position of the sleeve 11 will also move accordingly in the two sets of grooves 13. The final position of the sleeve 11 is the centroid of the triangle formed by the patient's umbilicus, phalangeal symphysis and anterior superior iliac crest. At this time, a water-resistant and abrasion-resistant oil pen is passed through the inside of the sleeve 11 to leave a mark on the patient's skin surface, which facilitates high-precision marking of the patient's surgical stoma position. The measured stoma position should be accurately recorded and carefully checked during the operation to ensure the accuracy and suitability of the stoma.
