[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1:

[0025] Please refer to Figures 1-4 , a nasal septum chisel, comprising a cutting head 1, a connecting rod 2 and a handle 3. It is characterized in that a semi-circular groove 101 is provided at the front end of the cutting head 1, the edge of the groove is sharp, and both sides are used to align the cutting target to improve the cutting force and accuracy;

[0026] The front end of the connecting rod 2 is bent twice by high-temperature treatment to form a first bending part 201 and a second bending part 202. The bending parts are bent by high-temperature treatment, and the front end is an integral part with the cutting head 1, and the rear end is welded to the handle 3;

[0027] The front end of the handle 3 is welded to the connecting rod 2, and the rear end of the handle 3 is a hammering handle 5, and the hammering handle 5 is in a fish-tail structure;

[0028] The side surface of the handle 3 is provided with an anti-slip pattern 4, and the shape of the anti-slip pattern 4 is grid-like, but the anti-slip pattern 4 does not extend to the hammering handle 5;

[0029] A guiding groove 102 is provided at the upper end of the cutting head 1, extending along the upper surface of the connecting rod 2 to the first bending part 201;

[0030] The connecting rod 2 is a seamless part, reducing the jamming of dirt, and the outer surface is smooth and easy to clean;

[0031] The rear end of the second bending part 202 is connected to the handle 3, and the bending arcs of both the first bending part 201 and the second bending part 202 are 140°, and the cutting head 1 is parallel to the handle 3.

[0032] In this embodiment, after the connecting rod 2 is heat-treated at high temperature and bent twice, a first bent portion 201 and a second bent portion 202 are formed. The bending arcs of the first bent portion 201 and the second bent portion 202 in the connecting rod 2 are both 140°. Moreover, the connecting rod 2 is a seamless part. The bent first bent portion 201 and second bent portion 202 in the connecting rod 2 can be used to excise nasal septum polyps and the like in a deviated nasal septum for patients with nasal septum deviation. The semi-circular groove 101 provided at the front end of the cutting head 1 has sharp groove edges, which can provide more accurate cutting force and precision for the cutting target. The grid-shaped anti-slip pattern 4 provided on the surface of the handle 3 can prevent the nasal septum chisel from slipping out of the doctor's hand when the doctor corrects the patient by hammering the hammering surface of the hammering handle 5 with too much force, causing harm to the patient. Moreover, the cutting head 1 is parallel to the handle 3, which can reduce the error in nasal septum correction.

[0033] Embodiment Two:

[0034] Please refer to Figures 1-4 , this embodiment provides a technical solution on the basis of Embodiment One: The hammering handle 5 has a fish-tail structure, with a thinner connecting part and a wider rear end. The side shape is similar to the tail of a fish, and the rear end has a larger bottom area, which is convenient for hammering force. At the same time, the surface is treated by high temperature, smooth and seamless.

[0035] In this embodiment, the hammering handle 5 is set to have a fish-tail structure. The end face connected to the handle 3 is thinner, and the end face receiving the hammering is wider, and the force-receiving area is large. It is beneficial to precisely control the cutting action of the nasal septum chisel by hammering the hammering handle 5 with different forces when correcting or excising the nasal septum. The hammering handle 5 increases the force-receiving surface through the fish-tail structure, so that during the process of hammering the hammering handle 5, it is possible to better exert force on the hammering handle 5, and it will not easily break away from the hammering surface during hammering. There is a buffer block inside the hammering handle 5 to prevent the nasal septum chisel cutting head 1 from causing harm to the patient's nasal septum when the hammering force on the hammering surface of the hammering handle 5 is too large.

[0036] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0037] During operation, first hold the handle 3. According to the condition of the patient's nasal septum, select a suitable nasal septum chisel. Adjust the nasal septum chisel to an appropriate angle according to the nasal septum, insert the connecting rod 2 into the nose, and through the semi-circular groove 101 provided at the front end of the cutting head 1, cut the nasal septum polyps with neoplastic lesions in the nasal septum. The sharp edge of the semi-circular groove 101 can precisely cut the nasal septum polyps. At the same time, through the guiding groove 102, the cut nasal septum polyps slide down through the guiding groove 102. When the patient's nasal septum is severely deviated, the nasal septum chisel can enter the deviated part of the nasal septum through the first bending part 201 and the second bending part 202 provided at the connecting rod 2, and excise the brown soft tissue that needs to be removed therein to prevent its regeneration, and expand the channels of the nasal cavity and sinuses to promote drainage, reducing symptoms such as sinus obstruction and inflammation. By hammering the hammering handle 5 with different forces, the doctor can precisely control the cutting action of the nasal septum chisel. The hammering handle 5 with a fish-tail structure increases the force-bearing area, making it possible to exert force on the hammering handle 5 better during the process of hammering the hammering handle 5, and it will not easily break away from the hammering surface during hammering. There is also a buffer block inside the hammering handle 5 to prevent the cutting head 1 of the nasal septum chisel from causing harm to the patient's nasal septum when the hammering force on the hammering surface of the hammering handle 5 is too large. The surface of the handle 3 is provided with anti-slip patterns 4. The grid shape of the anti-slip patterns 4 can increase the friction between the hand on the handle 3 and the handle 3 when hammering the hammering surface of the hammering handle 5, so that the nasal septum chisel will not easily slip out of the hand, preventing the nasal septum chisel from slipping out of the hand when hammering too hard and causing harm to the patient.
