Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a nasal prosthesis. Background Art

[0002] At present, prosthetic rhinoplasty is a common operation in plastic and cosmetic surgery. Silicone nasal prosthesis is the commonly used material. The principle is to place the carved nasal prosthesis into the peeled cavity through a small incision in the nasal vestibule, and gradually heal with the nasal tissue over time, thereby improving the facial image of the human body.

[0003] Before a prosthetic rhinoplasty operation, it is usually necessary to simulate the postoperative effect through a computer. Then, the doctor selects the original nasal prosthesis with the most matching shape according to the effect, and uses a scalpel to perform secondary processing on the nasal prosthesis in comparison with the expected postoperative effect, and finally obtains a personalized nasal prosthesis. Most of the existing nasal prostheses are manufactured based on related products from abroad. Because they do not conform to the nasal shape characteristics of the yellow race, doctors need to perform extensive carving and trimming. However, this operation method is not only time-consuming, but also highly dependent on the doctor's carving skills, which can easily affect the effect of the operation. Utility Model Content

[0038] First embodiment

[0039] The utility model provides a nasal prosthesis. Figure 1 and Figure 2 The first embodiment of the nasal prosthesis provided by the utility model is shown.

[0040] See also Figure 1 and Figure 2 In the first embodiment, the nose prosthesis 100 includes a nose tip 1 and a nose dorsum 2, the nose tip 1 includes a first nose tip segment 11 and a second nose tip segment 12, the first end of the first nose tip segment 11 is connected to the first end of the second nose tip segment 12, and the angle between the first nose tip segment 11 and the second nose tip segment 12 is set to be an acute angle; one end of the nose dorsum 2 is connected to the second end of the first nose tip segment 11, and the extension direction of the nose dorsum 2 is inclined by 6° to 10° relative to the extension direction of the first nose tip segment 11 in a direction away from the second end of the second nose tip segment 12.

[0041] Specifically, the nasal prosthesis 100 includes a nasal dorsum 2 , a nasal tip 1 , and a nasal columella 3 which are connected in sequence. The nasal dorsum 2 , the nasal tip 1 , and the nasal columella 3 are integrally formed to form an L-shaped nasal prosthesis 100 .

[0042] The nose tip 1 includes a first nose tip segment 11 and a second nose tip segment 12 connected to each other. The first nose tip segment 11 has a first end and a second end opposite to each other in the extension direction of the first nose tip segment 11. Similarly, the second nose tip segment 12 also has a first end and a second end opposite to each other in the extension direction of the second nose tip segment 12. The first end of the first nose tip segment 11 is connected to the first end of the second nose tip segment 12. Since the extension direction of the first nose tip segment 11 intersects with the extension direction of the second nose tip segment 12, an angle is formed between the first nose tip segment 11 and the second nose tip segment 12. The angle between the first nose tip segment 11 and the second nose tip segment 12 is usually 90°, and the angle between the first nose tip segment 11 and the second nose tip segment 12 is set to an acute angle, so that the nose tip 1 can better conform to the nose shape characteristics of the yellow race. For example, in the first embodiment, the angle between the first nose tip segment 11 and the second nose tip segment 12 is 85° or approximately 85°.

[0043] One end of the nasal dorsum 2 in the extension direction of the nasal dorsum 2 is connected to the second end of the first nose tip segment 11, and the nasal dorsum 2 includes a front side surface and a rear side surface that are opposite to each other in the thickness direction of the nasal dorsum 2, and the rear side surface of the nasal dorsum 2 is used to fit the human face. The nasal dorsum 2 is tilted forward by 6° to 10° relative to the first nose tip segment 11, so that the nasal dorsum 2 can better conform to the nose shape characteristics of the yellow race. For example, in the first embodiment, the extension direction of the nasal dorsum 2 is tilted by 6.74°, 7.15° or 8° relative to the extension direction of the first nose tip segment 11 in the direction away from the second end of the second nose tip segment 12.

[0044] Optionally, see Figure 1 and Figure 2 In the first embodiment, the length of the nose dorsum 2 is equal to or approximately twice the length of the first nose tip segment 11. By optimizing the length ratio of the nose dorsum 2 to the first nose tip segment 11, the nose prosthesis 100 can better conform to the nose shape characteristics of the yellow race.

[0045] The nose tip 1 of the nose prosthesis 100 of the present invention is set at an acute angle, and the nose dorsum 2 is set to be inclined at 6° to 10° relative to the first nose tip section 11 of the nose tip 1, so that the nose prosthesis 100 can better conform to the nose shape characteristics of the yellow race, thereby reducing the workload of the doctor in carving and trimming the nose prosthesis 100 when using the nose prosthesis 100.

[0046] One end of the columella 3 in the extension direction of the columella 3 is connected to the second end of the second nose tip segment 12. Figure 1 and Figure 2 In the first embodiment, the extension direction of the columella 3 is inclined by 5° to 9° relative to the extension direction of the second nose tip segment 12 toward a direction away from the second end of the first nose tip segment 11 .

[0047] Specifically, the columella 3 includes an upper side surface and a lower side surface that are opposite to each other in the thickness direction of the columella 3, and the upper side surface of the columella 3 is used to fit the human face. The columella 3 is tilted downward by 5° to 9° relative to the second nose tip segment 12, so that the columella 3 can better conform to the nose shape characteristics of the yellow race. For example, in the first embodiment, the extension direction of the columella 3 is tilted by 7° or 8° relative to the extension direction of the second nose tip segment 12 toward the direction away from the second end of the first nose tip segment 11.

[0048] Optionally, see Figure 1 and Figure 2 In the first embodiment, the length of the columella 3 is equal to or approximately twice the length of the second nose tip segment 12. By optimizing the length ratio of the columella 3 to the second nose tip segment 12, the nose prosthesis 100 can better conform to the nose shape characteristics of the yellow race.

[0049] Optionally, see Figure 1 and Figure 2 In the first embodiment, the length of the columella 3 is smaller than the length of the nasal dorsum 2 .

[0050] Optionally, see Figure 1 and Figure 2 In the first embodiment, the width of the columella 3 is smaller than the width of the nasal dorsum 2 .

[0051] Optionally, see Figure 1 and Figure 2 In the first embodiment, the thickness of the columella 3 is smaller than the thickness of the nasal dorsum 2 .

[0052] Specifically, by setting the size of the columella 3 to be smaller than the size of the nasal dorsum 2, the workload of the doctor in carving and trimming the nasal prosthesis 100 can be reduced when using the nasal prosthesis 100. The size includes at least one of a length value, a width value, and a thickness value.

[0053] Second embodiment

[0054] The utility model provides a nasal prosthesis. Figure 3 A second embodiment of the nasal prosthesis provided by the utility model is shown.

[0055] See also Figure 3 In the second embodiment, the nose prosthesis 100 includes a nose tip 1 and a nose dorsum 2, the nose tip 1 includes a first nose tip segment 11 and a second nose tip segment 12, the nose tip 1 includes the first nose tip segment 11 and the second nose tip segment 12, the first end of the first nose tip segment 11 is connected to the first end of the second nose tip segment 12, and the angle between the first nose tip segment 11 and the second nose tip segment 12 is set to be an acute angle; one end of the nose dorsum 2 is connected to the second end of the first nose tip segment 11, and the extension direction of the nose dorsum 2 is inclined by 6° to 10° relative to the extension direction of the first nose tip segment 11 in a direction away from the second end of the second nose tip segment 12.

[0056] Specifically, the nasal prosthesis 100 includes a nasal dorsum 2 and a nasal tip 1 which are connected in sequence. The nasal prosthesis 100 does not include the columella 3 in the first embodiment.

[0057] The nose tip 1 includes a first nose tip segment 11 and a second nose tip segment 12 connected to each other. The first nose tip segment 11 has a first end and a second end opposite to each other in the extension direction of the first nose tip segment 11. Similarly, the second nose tip segment 12 also has a first end and a second end opposite to each other in the extension direction of the second nose tip segment 12. The first end of the first nose tip segment 11 is connected to the first end of the second nose tip segment 12. Since the extension direction of the first nose tip segment 11 intersects with the extension direction of the second nose tip segment 12, an angle is formed between the first nose tip segment 11 and the second nose tip segment 12. The angle between the first nose tip segment 11 and the second nose tip segment 12 is usually 90°, and the angle between the first nose tip segment 11 and the second nose tip segment 12 is set to an acute angle, so that the nose tip 1 can better conform to the nose shape characteristics of the yellow race. For example, in the second embodiment, the angle between the first nose tip segment 11 and the second nose tip segment 12 is 85° or approximately 85°.

[0058] One end of the nasal dorsum 2 in the extension direction of the nasal dorsum 2 is connected to the second end of the first nose tip segment 11, and the nasal dorsum 2 includes a front side surface and a rear side surface that are opposite to each other in the thickness direction of the nasal dorsum 2, and the rear side surface of the nasal dorsum 2 is used to fit the human face. The nasal dorsum 2 is tilted forward by 6° to 10° relative to the first nose tip segment 11, so that the nasal dorsum 2 can better conform to the nose shape characteristics of the yellow race. For example, in the second embodiment, the extension direction of the nasal dorsum 2 is tilted by 6.74°, 7.15° or 8° relative to the extension direction of the first nose tip segment 11 in a direction away from the second end of the second nose tip segment 12.

[0059] Optionally, see Figure 3 In the second embodiment, the length of the nose dorsum 2 is equal to or approximately twice the length of the first nose tip segment 11. By optimizing the length ratio of the nose dorsum 2 to the first nose tip segment 11, the nose prosthesis 100 can better conform to the nose shape characteristics of the yellow race.

[0060] The nose tip 1 of the nose prosthesis 100 of the present invention is set at an acute angle, and the nose dorsum 2 is set to be inclined at 6° to 10° relative to the first nose tip section 11 of the nose tip 1, so that the nose prosthesis 100 can better conform to the nose shape characteristics of the yellow race, thereby reducing the workload of the doctor in carving and trimming the nose prosthesis 100 when using the nose prosthesis 100.

[0061] Optionally, see Figure 3 In the second embodiment, the width and thickness of the second nose tip segment 12 are gradually reduced in the direction away from the first nose tip segment 11, which can reduce the workload of the doctor in carving and trimming the nose tip 1 when using the nose prosthesis 100.

[0062] Optionally, see Figure 3In the second embodiment, the end surface of the second end of the second nose tip segment 12 is a curved surface that protrudes in a direction away from the first nose tip segment 11. The end surface of the second end of the second nose tip segment 12 is a curved surface that protrudes backward.

[0063] Optionally, see Figure 3 In the second embodiment, the angle between the center line of the second nose tip segment 12 and the extension direction of the second nose tip segment 12 is 5° to 9°. For example, in the second embodiment, the angle between the center line of the second nose tip segment 12 and the extension direction of the second nose tip segment 12 is 7.5°.

[0067] Specifically, the nasal prosthesis 100 is arranged in a rod shape, and by setting the size value of the columella 3 to be smaller than the size value of the nasal dorsum 2, the workload of the doctor in carving and trimming the nasal prosthesis 100 when using the nasal prosthesis 100 can be reduced.
