In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0022] Example 1

[0023] like Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a rhinoplasty micro-surgery rib cartilage slicer, including a box body 1, a pushing component 2 is arranged at the rear end of the inner cavity of the box body 1, the pushing component 2 includes a slide groove 201, a through hole 202, a push plate 203, a connecting rod 204, a slider 205, a first spring 206 and a fixing block 207, the pushing component 2 is used to push the rib cartilage to move, a slicing component 3 is arranged at the front end of the inner cavity of the box body 1, the slicing component 3 includes a mounting plate 301, a push rod 302, a pressing block 303 and a cutting knife 304, the slicing component 3 is used to cut the rib cartilage, and a limiting component 4 is also arranged at the front end of the inner cavity of the box body 1, the limiting component 4 includes a limiting rod 401, a second spring 402 and a limiting hole 403, and the limiting component 4 is used to limit the movement trajectory of the slicing component 3.

[0024] like Figure 1-4As shown, the rib cartilage is placed at the front end of the inner cavity of the box body 1, and the rib cartilage can be fixed by means of a pressure plate, and then the fixing block 207 is pushed, and the fixing block 207 pushes the connecting rod 204 to move forward through the slider 205. When the connecting rod 204 moves, it pushes the push plate 203 to move forward along the inner cavity of the through hole 202. When the push plate 203 moves, it pushes the rib cartilage forward, presses the pressing block 303, and the pressing block 303 drives the push rod 302 to move downward, so that the push rod 302 pushes the mounting plate 3 01 moves downward, and when the mounting plate 301 moves downward, it drives the cutter 304 to cut the rib cartilage. When the mounting plate 301 moves downward, it moves downward along the surface of the limiting rod 401 through the limiting hole 403, and squeezes the second spring 402, so that the second spring 402 is deformed under the force. The restoring elastic force of the second spring 402 can buffer the impact force of the mounting plate 301, and the limiting rod 401 and the limiting hole 403 can limit the movement trajectory of the mounting plate 301.

[0025] Example 2

[0026] Reference Figure 1-3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0027] In this embodiment, the slide groove 201 is opened at the top of the box body 1, the through hole 202 is opened on the inner wall of the box body 1, the connecting rod 204 and the first spring 206 are both installed at the rear end of the inner cavity of the box body 1, the push plate 203 is installed at the front end of the inner cavity of the box body 1, and the fixed block 207 is located at the top of the box body 1.

[0028] One end of the connecting rod 204 passes through the through hole 202 and is fixedly connected to the push plate 203 , the other end of the connecting rod 204 is fixedly connected to the first spring 206 , and one end of the first spring 206 away from the connecting rod 204 is fixedly connected to the inner wall of the box body 1 .

[0029] One end of the slider 205 is fixedly connected to the connecting rod 204 , and the other end of the slider 205 passes through the slide groove 201 and is fixedly connected to the fixing block 207 , and is slidably connected to the inner cavity of the slide groove 201 .

[0030] like Figure 1-3 As shown, the fixed block 207 is pushed, and the fixed block 207 pushes the connecting rod 204 forward through the slider 205. When the connecting rod 204 moves, it pushes the push plate 203 forward along the inner cavity of the through hole 202. When the push plate 203 moves, it pushes the rib cartilage forward, thereby facilitating the cutting of the rib cartilage. When the slider 205 moves, it moves along the inner cavity of the slide groove 201. The slide groove 201 can limit the movement trajectory of the slider 205. The first spring 206 can increase the resistance of the push plate 203 and improve the stability of the movement of the push plate 203.

[0031] Example 3

[0032] Reference Figure 1 , 2 and 4, which are the third embodiment of the present utility model, and this embodiment is based on the first two embodiments.

[0034] The limiting hole 403 is opened on the surface of the mounting plate 301, and both ends of the limiting rod 401 pass through the limiting hole 403 and are fixedly connected to the inner wall of the box body 1. The second spring 402 is sleeved on the surface of the limiting rod 401, one end of the second spring 402 is fixedly connected to the mounting plate 301, and the other end of the second spring 402 is fixedly connected to the inner wall of the box body 1.

[0035] like Figure 1 , 2 As shown in Figure 4, the pressing block 303 is pressed, and the pressing block 303 drives the push rod 302 to move downward, so that the push rod 302 pushes the mounting plate 301 to move downward. When the mounting plate 301 moves downward, it drives the cutter 304 to cut the rib cartilage. When the mounting plate 301 moves downward, it moves downward along the surface of the limiting rod 401 through the limiting hole 403, and squeezes the second spring 402, so that the second spring 402 is deformed by the force. The restoring elastic force of the second spring 402 can buffer the impact force of the mounting plate 301, and the limiting rod 401 and the limiting hole 403 can limit the movement trajectory of the mounting plate 301.

[0036] When in use, the rib cartilage is first placed at the front end of the inner cavity of the box body 1, and then the fixing block 207 is pushed. The fixing block 207 pushes the connecting rod 204 forward through the slider 205. When the connecting rod 204 moves, it pushes the push plate 203 forward along the inner cavity of the through hole 202. When the push plate 203 moves, it pushes the rib cartilage forward and presses the pressing block 303. The pressing block 303 drives the push rod 302 to move downward, so that the push rod 302 pushes the mounting plate 301 to move downward. When the mounting plate 301 moves downward, it drives the cutter 304 to cut the rib cartilage. When the mounting plate 301 moves downward, it moves downward along the surface of the limiting rod 401 through the limiting hole 403, and squeezes the second spring 402, so that the second spring 402 is deformed by the force. The restoring elastic force of the second spring 402 can buffer the impact force of the mounting plate 301, and the limiting rod 401 and the limiting hole 403 can limit the movement trajectory of the mounting plate 301.
