Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features described in the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
The magnetic nasal septum fixing device of this example includes the backup pad 1 that the fig. 1 shows and the magnetism that the fig. 4 shows inhale post 2, is provided with a plurality of fixed orificess 11 in the backup pad 1, and the magnetism is inhaled post 2's quantity and is corresponding to the quantity of fixed orificess 11, and magnetism is inhaled post 2 and is fixed in fixed orificess 11. The two are combined as shown in fig. 7.
The magnetic nasal septum fixing device provided by the embodiment is generally used by two matched modes, and the nasal septum is clamped by the magnetic attraction force through one nasal cavity on the left and the right.
The support plate 1 shown in fig. 1, 2 and 3 is made of silica gel by 3D printing, has certain flexibility and elasticity, and is of a rectangular structure.
A plurality of fixing holes 11 are arranged in the supporting plate 1, 10 fixing holes 11 are arranged in the length direction, and 6 fixing holes 11 are arranged in the width direction. As shown in fig. 3, the fixing hole 11 is a blind hole, the bottom end of the fixing hole 11 is closed, and the outer end has an open end (i.e., the lower end in fig. 3). The open end is inserted by the magnetic attraction column 2. The fixing holes 11 of this example are distributed in an array, and the number of the fixing holes 11 in the longitudinal direction and the width direction is not particularly limited.
The fixing hole 11 is a columnar body having a circular cross section. In other embodiments, the cross-section may also be polygonal.
As shown in fig. 4, the magnetic attraction column 2 is cylindrical in whole, narrow in tip and wide in bottom, and comprises a shell 21, a main core 22 and a spring 23. The shell 21 and the spring 23 are made of insulated metal, the shell 21 is made of stainless steel, the spring 23 is made of high-carbon steel, and the main core 22 is made of neodymium iron boron permanent magnet.
The housing 21 and the spring 23 may also be made of degradable or non-degradable materials.
As shown in fig. 5, the housing 21 has a sliding cavity 212 inside, the sliding cavity 212 has an opening 213, and the housing 21 at the edge of the opening 213 is retracted to form a limit stop bar 211.
As shown in fig. 6, the main core 22 includes a first section 221 and a second section 222. The diameter of the first section 221 is smaller than that of the second section 222, so that the front end of the second section 222 forms a stopper surface 2221 around the outer circumferential surface of the first section 221. The stop surface 2221 is blocked by the stop bar 211 shown in fig. 5, producing an effect that the second section 222 is defined within the housing 21. In this example, although only the second section 222 is defined in the housing 21, that is, only a portion of the main core 22 is defined in the housing 21, in other embodiments, the entire main core 22 may be defined in the housing 21, and then a soft pad or the like may be adhered to the front end of the main core 22 for abutting against the nasal septum.
As shown in fig. 4, a spring 23 is provided between the inner end of the main core 22 and the bottom surface of the housing 21. The spring 23 is in a compressed state for urging the main core 22 to protrude upward. The spring 23 may be further compressed to provide a sliding space for the downward movement of the main core 22. The position of the spring 23 is not limited as long as the spring 23 functions to urge the main core 22 to move outside the housing 21.
The first section 221 is exposed outside the housing 21. The outer peripheral surface of the first section 221 has a zinc plating layer. In this example, the entire outer peripheral surface of the main core 22 has a zinc plating layer, that is, the outer peripheral surfaces of the first section 221 and the second section 222 have zinc plating layers. And the front end periphery of the first section 221 has rounded corners to prevent scratching of soft tissue.
After the magnetic attraction post 2 is placed into the fixing hole 11 from the open end of the fixing hole 11 shown in fig. 1, the magnetic attraction post 2 can be fixed with the inner wall or the bottom wall of the fixing hole 11 by using an adhesion or welding mode, and the magnetic attraction post 2 can also be fixed with the inner wall and the bottom wall of the fixing hole 11 at the same time.
In this example, although the fixing holes 11 are arranged in an array on one surface of the support plate 1, there may be various arrangements, such as a plurality of rows or columns, and the rows and columns may or may not be aligned. The fixing holes 11 can be distributed on one side surface of the supporting plate 1 irregularly, and the positions of the fixing holes 11 on the supporting plate 1 of the left nasal cavity and the right nasal cavity are corresponding.
The backup pad 1 of this example is printed by silica gel 3D and is made, has certain compliance and elasticity, does benefit to the installation and the fixed of post 2 are inhaled to the magnetism. At this time, the doctor can cut and tailor according to the shape of the wound surface of the patient. The support plate 1 may also be made of other polymer materials.
The support plate 1 may also be made of a metal material and preset with a square, rectangle, trapezoid or diamond shape for post-operative selection.
The support plate 1 may also be manufactured by laser sintering, laser engraving or injection moulding.
As shown in fig. 7, when two magnetic nasal septum fixing devices are used in cooperation, they are disposed on two sides of the nasal septum 3, and the corresponding main cores 22 have opposite magnetic poles, so as to generate an attractive effect. Due to the scalability of the main core 22, the main core 22 is better attached to the tissues, and can be well adapted to the concave-convex tissue structure of the nasal cavity.
In summary, the advantages of the magnetic nasal septum fixing device of the present embodiment can be summarized as follows:
1. the main core 22 has a telescopic function, can adapt to the concave-convex structure of the nasal cavity, and ensures that the fitting performance of the fixing device is better;
2. the magnetic force of the main core 22 is utilized to achieve the fixing effect, so that complex operations such as sewing and the like can be avoided;
3. the main core 22 achieves the telescopic function by using the spring 23, so that the spring has good elasticity and better telescopic effect;
4. the support plate 1 made of silica gel is good in flexibility and elasticity, and is convenient for the installation and fixation of the magnetic suction column.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
