Technical Field

[0001] The invention relates to the technical field of rhinoplasty, in particular to a measuring device for nose alar resection. Background Art

[0002] Alar reduction surgery is mainly suitable for people with wide nose base or large nose wings. In the prior art, alar reduction surgery mainly includes the following steps: 1. Design and draw lines, and symmetrically design the excision reference line on both sides of the nose wing; 2. Use a scalpel to make a fusiform incision at the bottom of the nose wing along the reference line (the fusiform incision is made for the purpose of restoration and suturing); 3. Suture the fusiform incision.

[0003] When using the existing method to perform surgery, precise line drawing and design are required. In order to ensure symmetry of the resection on both sides, the doctor needs to spend a long time drawing the lines, which reduces the efficiency of the surgery. Summary of the invention

When in use, the center of the arc angle ruler is concentrically arranged with the hinge center of the first ruler body.

[0006] Furthermore, a hinge shaft is fixed at one end of the first scale body, a through hole is penetrated at one end of the second scale body, the hinge shaft movably passes through the through hole, and a limit plate is fixed at one end of the hinge shaft away from the first scale body, and the diameter of the limit plate is larger than the diameter of the through hole.

[0007] Furthermore, a screw is provided at one end of the arc angle ruler, a threaded hole is provided on the first ruler body, and the tail of the screw passes through the arc angle ruler thread and is adapted in the threaded hole.

[0008] Furthermore, a marking line is provided on the first ruler body, and a positioning arrow is provided on the side wall of the arc-shaped angle ruler. When the positioning arrow corresponds to the marking line, the center of the arc-shaped angle ruler is concentrically arranged with the hinge center of the first ruler body.

[0009] Furthermore, a magic hook surface is arranged at one end of the tape measure away from the first tape measure body, a magic plush surface is arranged on the first tape measure body, and the magic hook surface is magic-adhesive to the magic plush surface.

[0010] Furthermore, a thin positioning rod is fixed to one end of the first ruler away from the hinge, and the thin positioning rod is used to position the columella.

[0011] The beneficial effects of the present invention are: 1. The soft ruler can fit the nose wing for measurement, so as to adapt to the curvature of the patient's nose wing for measurement, and obtain the width of the nose wing, so that the width of the nose wing can be measured with higher measurement accuracy.

[0012] 2. Use the first ruler to correspond to the columella, and then make the second ruler contact the nose wing. Use the arc angle ruler to measure the angle between the nose wing and the columella. Combined with the width of the nose wing, the size of the nose wing resection can be obtained, so as to make accurate markings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0015] Embodiment 1 like Figures 1 to 5As shown, a measuring device for nose alar resection comprises a first ruler body 1, a second ruler body 2, a soft ruler 3 and an arc angle ruler 4. One end of the first ruler body 1 is hinged with one end of the second ruler body 2, one end of the arc angle ruler 4 is connected to the first ruler body 1, and one end of the soft ruler 3 is connected to the first ruler body 1. When in use, the center of the arc angle ruler 4 is concentrically arranged with the hinge center of the first ruler body 1. The soft ruler 3 is used to fit the nose alar to measure the width of the nose alar. The soft ruler 3 has good flexibility and can fit the curvature of the nose alar to measure the width of the nose alar. The measurement can make the width of the nose wing measured with higher measurement accuracy; a positioning thin rod 14 is fixed on the end of the first ruler 1 away from the hinge, and the positioning thin rod 14 is used to locate the columella. The positioning thin rod 14 is aligned with the columella, and then the second ruler 2 is deflected to make the second ruler 2 contact the nose wing. The arc angle ruler 4 is marked with an angle size. The angle between the nose wing and the columella is obtained through the corresponding position of the second ruler 2 on the arc angle ruler 4. The width of the nose wing resection is obtained in combination with the width size of the nose wing, so as to perform accurate marking.

[0016] Embodiment 2 Based on the first embodiment, Figure 1 As shown, a hinge shaft 5 is fixed at one end of the first scale body 1, and a through hole 7 is penetrated at one end of the second scale body 2. The hinge shaft 5 movably passes through the through hole 7. A limit plate 6 is fixed at the end of the hinge shaft 5 away from the first scale body 1. The diameter of the limit plate 6 is larger than the diameter of the through hole 7. The first scale body 1 and the second scale body 2 are hinged together by the setting of the hinge shaft 5. The limit plate 6 prevents the second scale body 2 from detaching from the hinge shaft 5, so that the connection between the first scale body 1 and the second scale body 2 is more stable.

[0017] Embodiment 3 Based on the second embodiment, Figures 1 to 5 As shown, a screw 8 is provided at one end of the arc angle ruler 4, a threaded hole 9 is provided on the first ruler body 1, the tail of the screw 8 passes through the arc angle ruler 4 and is threadedly adapted in the threaded hole 9, a magic hook surface 12 is provided at one end of the soft ruler 3 away from the first ruler body 1, a magic plush surface 13 is provided on the first ruler body 1, the magic hook surface 12 and the magic plush surface 13 are magic-adhesive, and the arc angle ruler 4 is detachably mounted on the first ruler body 1 by the screw 8, so that the arc angle ruler 4 can be conveniently disassembled for storage. When applying, loosen the screw 8 so that the arc angle ruler 4 can rotate on the first ruler body 1, so that the arc angle ruler 4, the first ruler body 1 and the second ruler body 2 are stacked together, and then use the soft ruler 3 to wind the arc angle ruler 4, the first ruler body 1 and the second ruler body 2 together. When the soft ruler 3 is wound, the screw 8 is wrapped inside to prevent the screw 8 from falling. After the soft ruler 3 is wound, the magic hook surface 12 and the magic plush surface 13 are fitted to stabilize the winding state of the soft ruler 3, so that the entire measuring ruler can be stored for easy storage.

[0018] Embodiment 4 Based on the third embodiment, Figure 1 As shown, a marking line 10 is provided on the first ruler body 1, and a positioning arrow 11 is provided on the side wall of the arc angle ruler 4. When the positioning arrow 11 corresponds to the marking line 10, the center of the arc angle ruler 4 is concentrically arranged with the hinge center of the first ruler body 1. Since the arc angle ruler 4 can be rotatably stored, when in use, it is necessary to make the center of the arc angle ruler 4 concentric with the hinge center of the first ruler body 1, otherwise the angle between the nose wing and the columella cannot be accurately measured. Therefore, the positioning arrow 11 and the marking line 10 are provided, and the arc angle ruler 4 is deflected so that the positioning arrow 11 points to the marking line 10 and then the screw 8 is tightened, so that the use position of the arc angle ruler 4 can be quickly located, and the operation is simple and quick.
