[0027] Reference Figures 1 to 4 The wound suturing aid ruler of this utility model is illustrated in the following embodiment:
[0028] A wound suturing aid ruler includes: a first ruler body 100 and a second ruler body 200.
[0029] Both the first ruler 100 and the second ruler 200 are elongated thin plates. Both the first ruler 100 and the second ruler 200 are provided with scale markings. These scale markings extend along the length of the first ruler 100 and the second ruler 200, respectively. The ends of the first ruler 100 and the second ruler 200 are rotatably hinged to each other, allowing them to rotate relative to each other, thus switching between overlapping and perpendicular positions.
[0030] In practical use, the wound suturing aid ruler of this invention is placed beside the wound to be sutured. The first ruler body 100 and the second ruler body 200 are rotated relative to each other until they are perpendicular, thereby providing reference points in different directions through the scale marks on the first ruler body 100 and the second ruler body 200, making it easy to grasp the needle insertion and exit distance. When not in use, the second ruler body 200 can be flipped to overlap with the first ruler body 100, thus facilitating storage.
[0031] like Figure 1 and Figure 2 As shown, further, in order to provide reference benchmarks for needle insertion and exit on both sides of the wound, the wound suturing auxiliary ruler also includes: a slider 300 and a third ruler body 400. The slider 300 is slidably sleeved on the second ruler body 200 along the length direction of the second ruler body 200, and one end of the third ruler body 400 is rotatably hinged to the slider 300.
[0032] In this embodiment, the third ruler 400 is in the shape of a long, thin plate, and has scale markings extending along its length. The third ruler 400 can rotate to a position perpendicular to the second ruler 200 and parallel to the first ruler 100. The slider 300 can slide along the length of the second ruler 200, allowing the distance between the third ruler 400 and the first ruler 100 to be freely adjusted. In actual use, the first ruler 100 and the third ruler 400 can be arranged parallel to each other on both sides of the wound, providing size markings for the needle insertion and exit positions on both sides of the wound. When storing, the third ruler 400 can rotate to overlap with the second ruler 200, achieving folded storage with the first ruler 100, second ruler 200, and third ruler 400 overlapping.
[0033] The first ruler 100 is located on one side of the second ruler 200, and the slider 300 and the third ruler 400 are located on the other side of the second ruler 200, so that the first ruler 100 and the third ruler 400 can overlap with the second ruler 200 without hindering each other from folding and thus maintaining a small storage volume.
[0034] A guide bar 310 and a slide groove 210 extending along the length direction of the second ruler 200 are respectively provided between the second ruler 200 and the slider 300, and the guide bar 310 is slidably embedded in the slide groove 210.
[0035] See attached document Figure 2In this embodiment, the second ruler 200 has grooves 210 on both sides of its width direction. The slider 300 has guide strips 310 on both sides, which are slidably embedded in the two grooves 210. The slider 300 and the second ruler 200 are slidably connected via the guide strips 310 and the grooves 210. In other embodiments, the grooves 210 may be provided on the slider 300, and guide strips 310 may be provided on both sides of the second ruler 200.
[0036] To avoid obscuring the skin around the patient's wound, the first ruler 100, the second ruler 200, and the third ruler 400 are all made of transparent material. Specifically, in this embodiment, the first ruler 100, the second ruler 200, and the third ruler 400 are made of transparent grade polyetheretherketone (PEEK). Polyetheretherketone is a functional polymer material that can be blow-molded into transparent tubes, calendered into sheets of different thicknesses, and injection molded into high-strength transparent plastic parts of different shapes using injection molding machines with high screw diameter ratios. In some other embodiments, for cost control purposes, the first ruler 100, the second ruler 200, and the third ruler 400 may be made of transparent acrylic. In other embodiments, the materials of the first ruler 100, the second ruler 200, and the third ruler 400 may also be: transparent polystyrene (PHB), polystyrene (commonly known as "transparent polystyrene"), high-strength plexiglass (polymethyl methacrylate), poly(p-phenylene terephthalamide) (polyarylate), etc.
[0037] In this embodiment, the corners of the first ruler 100, the second ruler 200, and the third ruler 400 are all rounded, and the edges of the first ruler 100, the second ruler 200, and the third ruler 400 are all polished to remove sharp edges, so as to avoid scratching the patient's skin or the gloves of medical staff.
[0038] In a further embodiment, a first limiting part 110 is provided between the first ruler body 100 and the second ruler body 200, the first limiting part 110 being used to limit the relative rotation angle between the second ruler body 200 and the first ruler body 100. A second limiting part 320 is provided between the slider 300 and the third ruler body 400, the second limiting part 320 being used to limit the relative rotation angle between the third ruler body 400 and the slider 300.
[0039] The first limiting part 110 restricts the rotation angle range of the second ruler 200 relative to the first ruler 100 to within 90 degrees, allowing the second ruler 200 to rotate precisely to coincide with or be perpendicular to the first ruler 100 at its two rotational limit positions, making it more convenient to use. The second limiting part 320 restricts the rotation angle range of the third ruler 400 relative to the slider 300 to within 90 degrees, allowing the third ruler 400 to be perpendicular or parallel to the second ruler 200 at its two rotational limit positions, making it more convenient to unfold for use or fold for storage.
[0040] See attached document Figure 2 With the length direction of the first ruler 100 as the front-back direction, the second ruler 200 has a rotation axis extending in the vertical direction, and the end of the second ruler 200 is rotatably connected to the front end of the first ruler 100. The second ruler 200 is located on the upper side of the first ruler 100, and the slider 300 and the third ruler 400 are both located on the upper side of the second ruler 200.
[0041] like Figure 3 As shown, the first limiting portion 110 is disposed on the upper front end of the first ruler body 100. The first limiting portion 110 has a first lateral limiting surface 111 and a first longitudinal limiting surface 112 that are perpendicular to each other. The first lateral limiting surface 111 extends in the left-right direction, and the first longitudinal limiting surface 112 extends in the front-back direction. When the second ruler body 200 rotates to extend in the front-back direction, its front end edge abuts against the first longitudinal limiting surface 112; when the second ruler body 200 rotates to extend in the left-right direction, its front end edge abuts against the first lateral limiting surface 111.
[0042] Similarly, such as Figure 3 As shown, the second limiting part 320 is disposed on the upper side of the slider 300. The second limiting part 320 has a second transverse limiting surface 321 and a second longitudinal limiting surface 322 that are perpendicular to each other. The second transverse limiting surface 321 extends along the length direction of the second ruler 200. When the third ruler 400 rotates to coincide with the second ruler 200, the edge of the end of the third ruler 400 connected to the slider 300 abuts against the second transverse limiting surface 321. When the third ruler 400 rotates to be perpendicular to the second ruler 200, its end edge abuts against the second longitudinal limiting surface 322.
[0043] In this embodiment, a hinge sleeve 120 is provided at the hinge position of the first ruler body 100 and the second ruler body 200. Both the first ruler body 100 and the second ruler body 200 are rotatably sleeved on the outside of the hinge sleeve 120. The hinge sleeve 120 is cylindrical in shape and has a through hole 121 extending along the axial direction.
[0044] The first ruler body 100 and the second ruler body 200 are hinged to each other by a hinge bushing 120. The through hole 121 can facilitate the hanging of the wound suturing auxiliary ruler or place it by a hanging rope or hook.
[0045] In this embodiment, a connecting post is provided on the upper side of the slider 300, and the end of the third ruler 400 is rotatably sleeved on the connecting post, thereby realizing the rotatable connection between the third ruler 400 and the slider 300. In other embodiments, the end of the third ruler 400 is provided with a stud that is threadedly connected to the slider 300. By screwing the stud, the third ruler 400 and the slider 300 can be locked together, thereby realizing the detachable adjustment of the third ruler 400 and the slider 300.
