Description

Technical Field

[0001] The utility model relates to the technical field of nasal bone punching, in particular to a nasal bone puncher. Background Art

[0002] In the field of medical aesthetics, plastic surgery is often performed on the nose. During the surgery, it is often necessary to use a nasal bone punching instrument to punch holes, so as to further assist other instruments in intraoperative operations such as sutures. In plastic surgery, calcification of the nasal cartilage often occurs, resulting in the hardness of the nasal cartilage and making it inconvenient to punch holes. In order to facilitate the punching, in the prior art, punching pliers are usually used to extend into both sides of the nasal cartilage to punch holes, such as the patent with publication number CN217020701U, which discloses anterior nasal spine punching pliers. Specifically, a punching head and a punching sleeve are arranged at the ends of a pair of hinged pliers handles, and the punching head and the punching sleeve are placed on both sides of the nasal cartilage to operate the pliers handle to achieve punching;

[0003] However, in actual plastic surgery, due to the different shapes of nasal deformities and the shapes and sizes of nasal bones of the patients, especially for those with smaller nostrils and smaller nasal bones, the punching head and the punching sleeve may not be able to be inserted into the nostrils at the same time to perform precise punching operations. In addition, if the force is insufficient at the moment of punching, the operation will be required again, and repeated operations may easily lead to nasal bone splitting, and there will be tissue residue after punching. The diameter of the nose hole is small, and there will be residue after punching that blurs the hole, thereby interfering with the operator's judgment of the hole position.

[0004] Based on the above description, there is an urgent need for a nasal bone puncher that is easy to punch accurately and not prone to splitting. Utility Model Content

[0006] The embodiments of the present invention are implemented by the following technical solutions:

[0007] A nasal bone puncher comprises a pair of hinged pliers handles, a punching elbow, a punching sleeve and a telescopic assembly; the telescopic assembly comprises a pair of connecting pieces and a tension spring; the tension spring is connected between the pair of pliers handles through the pair of connecting pieces; the punching elbow and the punching sleeve are respectively detachably connected to the pair of pliers handles.

[0008] Preferably, the pliers handle comprises a connecting end; the connecting end is provided with a screw hole; the punched elbow is embedded in the screw hole and is screwed to the connecting end.

[0009] Preferably, the pliers handle comprises a connecting end; the connecting end is provided with a clamping hole; the punched elbow is embedded in the clamping hole and clamped with the connecting end.

[0010] Preferably, the connecting member includes a screw and a connecting plate; one end of the connecting plate is connected to the tension spring; the other end of the connecting plate is connected to the pliers handle via the screw; and the screw is passed through the pliers handle.

[0011] Preferably, the punching sleeve comprises an outer cover body, a buffer groove and a first bent rod; the notch of the buffer groove faces the punching elbow; the buffer groove is arranged in the outer cover body; the outer cover body is sleeved on the first bent rod; the end of the outer cover body away from the bent rod is sealed with a multi-petal elastic sheet for the punching elbow to pass through.

[0012] Preferably, a through hole is arranged around the middle of the multi-petal elastic sheet; the through hole is opposite to the notch of the buffer groove.

[0013] Preferably, the perforating elbow comprises a puncturing end and a second curved rod; an annular spring piece is provided on the outside of one end of the puncturing end close to the second curved rod; and the diameter of the annular spring piece is larger than the aperture of the perforation.

[0014] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

After determining the position, operate the pliers handle 1, and at the same time, the stretched tension spring 42 is restored, thereby pulling the pair of pliers handles 1 together, and then through the elastic force generated during contraction and the cooperation of manual force, the punching elbow 2 quickly approaches the punching sleeve 3, so that the punching elbow 2 is used to perform rapid and accurate puncture and drilling, and the nasal bone splitting caused by insufficient force is effectively avoided; wherein, the punching elbow 2 and the punching sleeve 3 are both inserted at the end of the pliers handle 1 and are detachably connected to the pliers handle 1, so that it is convenient to replace the punching elbow 2 and the punching sleeve 3 according to the shape of the nose and the punching requirements, thereby improving the scope of application, and facilitating the recycling of the pliers handle 1.

[0026] Specifically, Figure 1 As shown, the pliers handle 1 includes a connecting end 11 ; the connecting end 11 is provided with a screw hole; the punched elbow 2 is embedded in the screw hole and is screwed to the connecting end 11 .

[0027] In this embodiment, the clamp handle 1 and the punch elbow 2 are detachably connected by screw connection. Similarly, the clamp handle 1 and the punch sleeve 3 are also detachably connected by screw connection.

[0028] Specifically, Figure 1 As shown, the pliers handle 1 includes a connecting end 11 ; the connecting end 11 is provided with a clamping hole; the punching elbow 2 is embedded in the clamping hole and clamped with the connecting end 11 .

[0029] In the present embodiment, the pliers handle 1 and the punching elbow 2 are detachably connected by replacing the screw connection with a snap-in connection. Similarly, the pliers handle 1 and the punching sleeve 3 are also detachably connected by a snap-in connection. Specifically, a slot is provided in the connecting end 11 of the pliers handle 1, and an elastic block is provided on the outer side wall of one end of the pliers handle 1 through which the punching elbow 2 or the punching sleeve 3 passes.
