In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figure 1 , Figure 2 As shown, a specific implementation of the nasal surgical instrument provided in this embodiment includes: a handle 1, a blade head 2 and a stripper, the blade head 2 is installed at one end of the handle 1, and the stripper is installed at the other end of the handle 1. One side of the blade tip 3 of the blade head 2 is an outer arc-shaped blade 4, and the other side is a diagonal blade 5.

[0032] The nasal surgical instrument provided in this embodiment has a blade tip 3 of the blade head 2 with an outer arc-shaped blade 4 on one side and an oblique blade 5 on the other side. When performing surgery in the nasal cavity, the outer arc-shaped blade 4 of the blade tip 3 is first used to open the incision, and then the blade head 2 is rotated to cut along the incision with the oblique blade 5 on the other side of the blade tip 3. There is no need to replace the blade head 2, thereby saving surgical time.

[0033] like Figure 1 , Figure 2As shown, in the nasal surgical instrument provided in this embodiment, the blade head 2 is installed on the handle 1 through the first extension rod 7. The first extension rod 7 is a cylindrical structure.

There is an angle of 30° between the blade head 2 and the first extension rod 7, which is convenient for surgery in the nasal cavity. In addition, as an alternative embodiment, the first extension rod 7 can also be omitted, and the end of the handle 1 connected to the blade head 2 can be set to a cylindrical structure.

[0034] like Figure 1 , Figure 2 As shown, in the nose surgical instrument provided in this embodiment, the outer arc blade 4 and the oblique blade 5 are integrally formed on the first extension rod 7. The integrally formed blade does not need to be subsequently installed, and the assembly is more convenient. In addition, as an alternative embodiment, the blade head 2 and the first extension rod 7 can also be a separate structure, connected together by welding or the like.

[0035] like Figure 1 , Figure 2 As shown, in the nasal surgical instrument provided in this embodiment, the first extension rod 7 has a scale structure along the length direction, and the scale structure can measure the distance that the blade head 2 extends into the nasal cavity, which is convenient for the staff to judge whether the blade head 2 reaches the surgical site and improve the surgical accuracy.

[0036] like Figure 1 , Figure 2 As shown, in the nasal surgical instrument provided in this embodiment, the periosteal stripper 6 is installed on the handle 1 through the second extension rod 9. The second extension rod 9 can increase the working range of the periosteal stripper 6, making it easier to perform surgery deep in the nasal cavity and more convenient to use. In addition, as an alternative embodiment, the second extension rod 9 can also be omitted, and the periosteal stripper 6 can be directly installed on the handle 1.

[0037] like Figure 1 , Figure 2 As shown, in the nasal surgical instrument provided in this embodiment, the periosteal stripper 6 and the second extension rod 9 are integrally formed, and the integrally formed manner does not require subsequent assembly of the various components, making installation more convenient. In addition, as an alternative embodiment, the periosteal stripper 6 and the second extension rod 9 can also be a split structure, connected together by welding or the like.

[0038] like Figure 1 , Figure 2 As shown, in the nasal surgical instrument provided in this embodiment, the second extension rod 9 has a scale structure along the length direction. In this embodiment, the scale structure of the second extension rod 9 is also a scale groove 8. The scale structure can measure the length of the second extension rod 9 extending into the nasal cavity, which is convenient for the staff to accurately control the working position of the periosteal stripper 6.

[0039] like Figure 1 , Figure 2 As shown, in the nose surgical instrument provided in this embodiment, the handle 1 is provided with a friction structure in the area used for holding, and the friction structure can increase the friction between the handle 1 and the palm, making the holding more stable. In addition, as an alternative embodiment, a groove for placing fingers can also be provided on the handle 1 to replace the friction structure, and the groove is a circular structure concave inward.

[0040] like Figure 1 , Figure 2 As shown, in the nasal surgical instrument provided in this embodiment, the friction structure is a friction block 10 arranged in a uniform array. In this embodiment, the friction block 10 can be a rubber block, and multiple friction blocks 10 are in contact with the palm to ensure sufficient friction. In addition, as an alternative embodiment, the friction structure can also be an annular rubber ring, which is sleeved on the outside of the handle 1.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present utility model.
