The bifurcated structure 200 is provided with a first leg 210 and a second leg 220, and one end of the first leg 210 and one end of the second leg 220 are integrally connected to the plant body 100.

It should be noted that the first leg 210 and the second leg 220 of the bifurcated structure 200 of the present invention can straddle the piriformis nasal crest, thereby being fixed at the front and lower end of the nasal septum cartilage to form an effective and stable nasal tip and columella bracket mechanism, and avoiding the occurrence of the phenomena of deviation, movement, displacement, abnormal sound and columella thickening of the columella implant.

An included angle A exists between the first supporting leg 210 and the second supporting leg 220, and the included angle A is larger than or equal to 30 degrees and smaller than or equal to 60 degrees. The length of the first supporting leg 210 and the length of the second supporting leg 220 are both B, and B is more than or equal to 5mm and less than or equal to 10 mm; the thickness of the first supporting leg 210 and the thickness of the second supporting leg 220 are both C, and C is larger than or equal to 1mm and smaller than or equal to 2mm, as shown in FIGS. 3 and 4.

Through multiple experiments, the integral stability of the columella nasi implant is best and the appearance after operation is better when the included angle of the first supporting leg 210 and the second supporting leg 220 is in the range of 30-60 degrees. The length of the first leg 210 and the length of the second leg 220 are both within 5mm to 10mm, and the thickness of the first leg 210 and the thickness of the second leg 220 are both within 1mm to 2mm, because too long and too thick will affect the appearance after operation, and too short and too thick will affect the stability of the whole, so the length and thickness are within the above range with the best effect.

When the columella nasi implant is used normally and the user is in the supine posture, the side abutting against the nasal crest of the piriform aperture is defined as the lower end, the side opposite to the lower end is the upper end, the upper side and the lower side of the head of the user are defined as the rear end and the front end of the columella nasi implant, and the bifurcating structure 200 is located at the lower end of the implant body 100, as shown in fig. 1.

The columella nasi implant of the utility model is also provided with at least a pair of wing-shaped structures 300 for preventing the implant main body 100 from shifting, and the pair of wing-shaped structures 300 are respectively and integrally connected with two sides of the rear end surface of the implant main body 100. The present embodiment is specifically provided with a pair of wing structures 300.

It should be noted that the wing-like structure 300 is used to place the front end of the cartilage of the nasal septum, i.e. both sides of the caudal lobe, and can be sutured and fixed to prevent the implant body from moving.

The length of the wing-shaped structure 300 is defined as F, and F is more than or equal to 5mm and less than or equal to 30 mm; the width of the wing-shaped structure 300 is defined as G, and G is more than or equal to 5mm and less than or equal to 10 mm; a parallel space exists between the pair of wing-shaped structures 300, the width of the parallel space is defined as H, and H is more than or equal to 1mm and less than or equal to 2mm, as shown in FIGS. 5 and 6.

It should be noted that, after many experiments, when the wing-like structure 300 has a length of 5mm to 30mm and a width of 5mm to 10mm, the stability of the whole columella implant is the best and the appearance after operation is better. The length and width are optimized within the above ranges because too long and too wide both affect the appearance after operation, while too short and too wide affect the overall stability. And when the parallel space is within the range, the nasal septum cartilage front end can be tightly attached, so that the qualitative performance is greatly improved.

The junction of the bifurcation structure 200 and the plant main body 100 is a transition structure 400; the connection between the wing-shaped structure 300 and the planting main body 100 is a transition structure 400.

It should be noted that the filter structure 400 of the present invention has the function of preventing the abrupt angle at the connection, so that the appearance after the operation is good.

The thickness of the plant body 100 is defined as I, and I is present in a range of 2mm < I.ltoreq.3 mm. It should be noted that when the planting body 100 is within the above range, the planting body 100 is in a sheet structure, and the original columella nasalis is not widened or thickened.

The columella nasi implant straddles on the piriformis nasal crest through the bifurcation structure 200, thereby preventing the columella nasi implant from displacement, deflection, movement, abnormal sound and columella nasi thickening; thereby greatly improving the overall stability, and simultaneously, the utility model does not need to take the cartilage of the user, thereby avoiding the cartilage taking operation.

Example 2.

A columella nasi implant, as shown in fig. 7, having other features the same as those of example 1 except that: the present embodiment does not have the wing-shaped structure 300, but the implant body 100 is provided with a groove 110 for clamping the nasal septum cartilage, the groove 110 is located at the rear end of the implant body 100, and the groove 110 penetrates through the rear end surface of the implant body 100 from top to bottom.

The groove 110 functions to hold the anterior end of the nasal septum cartilage therein, increasing the stability of the posterior end.

The depth of the groove 110 is defined as D, and D is more than or equal to 3mm and less than or equal to 6 mm; the maximum width of the groove 110 is defined as E, and there is 1 mm. ltoreq. E.ltoreq.2 mm, as shown in FIGS. 8 and 9.

It should be noted that, when the maximum width of the groove 110 is too large, the thickness of the implant body 100 is increased, and when the maximum width of the groove 110 is too small, the implant body cannot be clamped at the anterior end of the nasal septal cartilage.

Compared with embodiment 1, this embodiment does not need to add the wing-like structure 300, so that the width of the columella nasalis implant can be reduced, and the overall structure of the columella nasalis implant is simple.

Example 3.

A columella nasi implant, other features are the same as those of embodiment 1, further provided with: the implant body 100 is provided with a groove 110 for nasal septum cartilage clamping.

The present embodiment is integrally fixed by the bifurcated structure 200, the wing-like structure 300 and the recess 110, so that the columella implant of the present embodiment has the best stability compared to embodiments 1 and 2.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and any changes or substitutions that are not thought of by the inventive labor should be covered within the protection scope of the present invention.
