Description

Technical Field

[0001] This utility model relates to the field of rhinoplasty technology, specifically to a measuring device for nasal alar resection. Background Technology

[0002] Alar reduction surgery is mainly suitable for people with excessively wide nasal bases or excessively large nasal wings. Current techniques for alar reduction surgery mainly involve the following steps: 1. Design and drawing lines: symmetrically design resection reference lines on both sides of the nasal wings; 2. Using a scalpel, make a fusiform incision at the base of the nasal wing along the reference lines (the fusiform incision is for the purpose of restoration suturing); 3. Suture the fusiform incision.

[0003] Using existing methods for surgery requires precise line drawing and design. To ensure symmetrical resection on both sides, doctors need to spend a long time drawing the lines, resulting in low surgical efficiency. Utility Model Content

Detailed Implementation

[0020] The technical solution of this utility model is described in further detail below with reference to the accompanying drawings, but the scope of protection of this utility model is not limited to the following description.

[0021] Example 1

[0022] like Figures 1 to 5As shown, a measuring device for nasal alar resection includes a first ruler 1, a second ruler 2, a flexible ruler 3, and an arc-shaped angle ruler 4. One end of the first ruler 1 is hinged to one end of the second ruler 2. One end of the arc-shaped angle ruler 4 is connected to the first ruler 1, and one end of the flexible ruler 3 is connected to the first ruler 1. In use, the center of the arc-shaped angle ruler 4 is concentric with the hinge center of the first ruler 1. The flexible ruler 3 is used to measure the width of the nasal alar by fitting it against the nasal alar. The flexible ruler 3 has good flexibility and can conform to the curvature of the nasal alar. The measurement ensures high accuracy in measuring the width of the nasal ala. A positioning rod 14 is fixed at the end of the first ruler 1 away from the hinge. The positioning rod 14 is used to position the columella. The positioning rod 14 is aligned with the columella, and then the second ruler 2 is deflected so that it contacts the nasal ala. An angle dimension is marked on the arc-shaped angle ruler 4. The angle between the nasal ala and the columella is obtained by the corresponding position of the second ruler 2 on the arc-shaped angle ruler 4. Combined with the width dimension of the nasal ala, the width of the nasal ala resection is obtained, thus enabling precise marking.

[0023] Example 2

[0024] Based on Example 1, such as Figure 1 As shown, a hinge shaft 5 is fixed at one end of the first ruler body 1, and a through hole 7 is provided at one end of the second ruler body 2. The hinge shaft 5 moves through the through hole 7. A limiting plate 6 is fixed at the end of the hinge shaft 5 away from the first ruler body 1. The diameter of the limiting plate 6 is larger than the diameter of the through hole 7. The first ruler body 1 and the second ruler body 2 are hinged together by the hinge shaft 5. The limiting plate 6 prevents the second ruler body 2 from detaching from the hinge shaft 5, making the connection between the first ruler body 1 and the second ruler body 2 more stable.

[0025] Example 3

[0026] Based on Example 2, such as Figures 1 to 5 As shown, a screw 8 is provided at one end of the arc-shaped angle ruler 4, and a threaded hole 9 is provided on the first ruler body 1. The tail of the screw 8 passes through the arc-shaped angle ruler 4 and is threaded into the threaded hole 9. A magic hook-shaped surface 12 is provided at the end of the flexible ruler 3 away from the first ruler body 1, and a magic plush surface 13 is provided on the first ruler body 1. The magic hook-shaped surface 12 and the magic plush surface 13 are Velcro-attached. The arc-shaped angle ruler 4 is detachably installed on the first ruler body 1 by the screw 8, which facilitates the removal and storage of the arc-shaped angle ruler 4. During application, loosen screw 8 to allow the arc-shaped angle ruler 4 to rotate on the first ruler body 1, so that the arc-shaped angle ruler 4, the first ruler body 1, and the second ruler body 2 are stacked together. Then, use a flexible ruler 3 to wrap the arc-shaped angle ruler 4, the first ruler body 1, and the second ruler body 2 together. When wrapping the flexible ruler 3, the screw 8 is wrapped inside to prevent the screw 8 from falling off. After the flexible ruler 3 is wrapped, the wrapping state of the flexible ruler 3 is stabilized by the adhesion of the magic hook-shaped surface 12 and the magic plush surface 13, thereby storing the entire measuring ruler for easy storage.

[0027] Example 4

[0028] Based on Example 3, such as 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-shaped angle ruler 4. When the positioning arrow 11 corresponds to the marking line 10, the center of the arc-shaped angle ruler 4 is concentric with the hinge center of the first ruler body 1. Since the arc-shaped angle ruler 4 can be rotated and stored, it is necessary to make the center of the arc-shaped angle ruler 4 concentric with the hinge center of the first ruler body 1 during use. Otherwise, the angle between the nasal ala and the columella cannot be accurately measured. Therefore, the positioning arrow 11 and the marking line 10 are provided. After deflecting the arc-shaped angle ruler 4 so that the positioning arrow 11 points to the marking line 10, the screw 8 is tightened, so that the use position of the arc-shaped angle ruler 4 can be quickly positioned. The operation is simple and quick.
