In order to solve the problems of operation failure or multiple tools, inconvenience in operation, bone fracture and the like caused by insecure fixation after the existing nasal septum is corrected and easy to tear off and loosen, the utility model provides anterior nasal spine perforating pliers, which comprise a pliers handle I1 and a pliers handle II 2 which are hinged with each other as shown in figure 1, wherein the pliers handle I1 and the pliers handle II 2 are hinged in an X shape.

In the embodiment, the head end (i.e. the upper end in fig. 1) of the forceps handle I1 is provided with a bent arm I101, the end of the bent arm I101 is provided with a punching head 3, and the punching head 3 is of a pointed structure so as to punch a hole on the bone of the anterior nasal spine.

In order to realize stable and firm fixation, the size of the punching head 3 is set to be larger than the diameters of the curved needle and the suture for fixing the nasal septum, so that the diameter of the punched hole is larger than the diameters of the curved needle and the suture, and the curved needle and the suture can pass through the hole diameter once or for many times according to the fixation requirement, thereby achieving stable and firm fixation.

In this embodiment, the head end of the forceps handle II 2 is provided with a bent arm II 201, the bent arm II 201 is arranged opposite to the bent arm I101, the end of the bent arm II 201 is provided with a punching sleeve 4, the punching sleeve 4 is matched with the punching head 3, and the punching head 3 can penetrate through the front nasal spine to enter the punching sleeve 4 after punching.

Specifically, the cover 4 that punches of this embodiment is the infundibulate of fretwork, and punches the heavy-calibre end orientation head 3 that punches of cover 4, makes things convenient for head 3 that punches to insert like this. It should be noted that the shape of the punching sleeve 4 is not limited to the hollow funnel shape, and in other embodiments, the punching sleeve 4 may also be arranged in a cylindrical shape.

In order to realize operation in a narrow space, the inner contour formed by the curved arm I101 and the curved arm II 201 is a symmetrical pear shape in the present embodiment, as shown in fig. 2, the curved arm I101 of the present embodiment also forms an included angle of 25 to 35 ° with the extending direction (i.e. the vertical direction in fig. 2) of the forceps handle I1 or the forceps handle II 2, i.e. the middle section of the curved arm I101 is curved downwards in an arc shape, and the curved arm II 201 and the curved arm I101 have the same structure, thereby facilitating operation.

When the front nasal spine perforating clamp is used, force is applied by kneading the clamp handle I1 and the clamp handle II 2 to drive the perforating head 3 to perforate the sclerotin of the front nasal spine, and in order to enable the perforating head 3 to penetrate through the sclerotin of the front nasal spine, the hinging point of the clamp handle I1 and the clamp handle II 2 is arranged at 5/7-3/4 of the length of the clamp handle I/II to amplify the force applied at the perforating head 3.

Specifically, as shown in fig. 1, in this embodiment, a finger cot I5 is disposed at a tail end (i.e., a lower end in fig. 1) of the forceps handle I1, a finger cot II 6 is disposed at a tail end of the forceps handle II 2, a distance between a bottom end of the finger cot I5 and a hinge point is 2.5 to 3 times a distance between a bending point and a hinge point of the curved arm I101, and a distance between a bottom end of the finger cot II 6 and a hinge point is 2.5 to 3 times a distance between a bending point and a hinge point of the curved arm II 201, according to a lever principle, when the forceps handle I1 and the forceps handle II 2 are pressed and pinched, an amplification force of 2.5 to 3 times can be generated between the punching head 3 and the punching sleeve 4, so that the punching head 3 can penetrate anterior nasal spine bone.
