[0002] Rhinoplasty is the most common surgery in the field of plastic surgery, which is to change the height and shape of the nose by implanting appropriate materials to make it harmonious with other parts of the face.

[0003] In medicine, there are many kinds of rhinoplasty materials, such as medical silicone rubber, autologous cartilage, animal tendons or ligaments, expanded polytetrafluoroethylene, hyaluronic acid, etc. There are also many methods for preparing nose bridge prostheses. Among them, autologous cartilage will not be rejected because it comes from the body, and has become the mainstream implant material. The rib cartilage needs to be carved before implantation. The shape, size and thickness of the rib cartilage must be carved. Because it is used for rhinoplasty, the rib cartilage needs to be carved very thinly. Traditional carving is to place the rib cartilage on the operating table for carving. Then the height difference between the operating table and the doctor is large. The doctor carves the rib cartilage while looking down, which makes it difficult to observe the carving thickness of the rib cartilage. It is necessary to squat down for observation many times, which is very inconvenient. At the same time, the carving error when looking down is large, and the carving is easily scrapped.

[0025] Furthermore, an elastic rubber pad 21 is fixed to the outer end of the abutment block 3, and the elastic rubber pad 21 is compressed by the abutment block 3 to press against the inner wall of the hollow tube body, and the high friction force generated by the elastic rubber pad 21 is used to fix the installation position of the installation tube 1.

[0026] Embodiment 2

[0027] Based on the first embodiment, Figures 1 to 3 As shown, an inner cavity 4 is opened in the mounting tube 1 along its own axial direction, and a slide groove 5 is opened on the side wall of the mounting tube 1 at the position where the abutment block 3 is set, and the slide groove 5 is connected to the inner cavity 4. A pressure plate 6 is set in the inner cavity 4, and the pressure plate 6 has the freedom to move along the axial direction of the mounting tube 1. The abutment block 3 is slidably set in the slide groove 5, and a wedge surface 7 is provided on the top of the abutment block 3 close to one end of the pressure plate 6, and the wedge surface 7 is located on the moving path of the pressure plate 6. An elastic member is connected to the bottom of the abutment block 3, and the elastic member includes a spring 22, a pull wire 23 and a fixed pulley 24. The spring 22 is vertically set in the inner cavity 4, one end of the spring 22 is connected to the mounting tube 1, and the other end is connected to the pull wire 23, the fixed pulley 24 is installed on the side wall of the mounting tube 1 and is located below the abutment block 3. The pull wire 23 bypasses the fixed pulley 24 to connect the abutment block 3. A screw rod 8 is arranged in the inner cavity 4. The screw rod 8 is rotatably connected to the mounting tube 1. The pressure plate 6 is threadedly sleeved on the screw rod 8. A vertical slide groove 9 is opened along the inner wall of the mounting tube 1 along its own axial direction. A guide slider is fixed to the side wall of the pressure plate 6. The guide slider is slidably adapted in the vertical slide groove 9. A main shaft 10 is rotatably arranged on the inner wall of the mounting tube 1. One end of the main shaft 10 is connected to a first bevel gear 11. A second bevel gear 12 is sleeved on the screw rod 8. The second bevel gear 12 meshes with the first bevel gear 11. The main shaft 10 is rotated. The main shaft 10 passes through the first bevel gear The meshing of the wheel 11 and the second bevel gear 12 drives the screw 8 to rotate, and the rotational freedom of the pressure plate 6 is limited by the cooperation of the guide slider and the vertical slide groove 9, so that the pressure plate 6 moves linearly along the axial direction of the screw 8, and the pressure plate 6 moves downward to squeeze the wedge surface 7 of the abutment block 3. Under the action of the wedge surface 7, the abutment block 3 slides out of the slide groove 5 and moves close to the inner wall of the hollow tube body, so that the elastic rubber pad 21 is compressed and pressed against the inner wall of the hollow tube body. In the process of the abutment block 3 moving close to the inner wall of the hollow tube body, the spring 22 will be stretched through the pull wire 23, so that the spring 22 is in a stretched state. When it is necessary to disassemble the mounting tube 1, the main shaft 10 is rotated in the opposite direction to make the pressure plate 6 moves upward away from the abutment block 3, so that the pressure plate 6 is separated from the abutment block 3, and the abutment block 3 moves close to the screw rod 8 under the reaction force of the spring 22 and resets; it should be noted that since the radial space of the mounting tube 1 is limited and the axial space is larger, the axial space of the mounting tube 1 is used to install the spring 22 to ensure that the spring 22 of the required length can be installed. In order to ensure that the abutment block 3 can smoothly stretch the spring 22, the direction of the force is changed by the pull wire 23 and the fixed pulley 24, so that the force of the abutment block 3 to stretch the spring 22 is offset from the spiral line of the spring 22, so that the spring 22 can be smoothly stretched and deformed under the action of the component force, ensuring that the elastic member can smoothly drive the abutment block 3 to reset.

[0028] Embodiment 3

[0029] Based on the second embodiment, Figures 1 to 4 As shown, a driving shaft 13 is slidably penetrated at the other end of the main shaft 10, and a circular groove 14 is provided on the outer wall of the mounting tube 1. One end of the driving shaft 13 extends into the circular groove 14 and is connected to a limiting plate 15. A limiting tooth 16 is fixed to the side wall of the limiting plate 15. A plurality of tooth grooves 17 are provided on the inner wall of the circular groove 14 along its circumferential direction. The limiting tooth 16 is adapted in one of the tooth grooves 17. A rotation limiting groove 18 is provided on the inner wall of the main shaft 10 along its axial direction. A rotation limiting block 19 is fixed on the side wall of the driving shaft 13. The rotation limiting block 19 is slidably adapted in the rotation limiting groove 18. In order to prevent the main shaft 10 from accidentally deflecting and driving the screw rod 8 to rotate during the engraving process, resulting in an unstable connection of the mounting tube 1, a driving shaft 13 and a limiting plate 15 are further provided. When the main shaft needs to be rotated, When the shaft 10 is moved, the limit plate 15 is pulled out from the circular groove 14 to separate the limit teeth 16 from the tooth groove 17. The drive shaft 13 is driven to rotate by rotating the limit plate 15, so that the drive shaft 13 drives the main shaft 10 to rotate. The main shaft 10 drives the screw rod 8 to rotate through the engagement of the first bevel gear 11 and the second bevel gear 12, and the position adjustment of the abutment block 3 is completed. When the mounting tube 1 is installed on the hollow tube body, the limit plate 15 is pushed back into the circular groove 14, and the limit teeth 16 are adapted in one of the tooth grooves 17, thereby locking the rotational freedom of the limit plate 15, ensuring that the position of the abutment block 3 will not change during the engraving process, and having strong installation stability; the elastic deformation of the elastic rubber pad 21 can eliminate the error, so that the limit teeth 16 can be adapted to fit in the tooth groove 17.

[0030] Embodiment 4

[0031] Based on the third embodiment, Figures 1 to 3 As shown, an elastic sleeve 20 is fixed on the drive shaft 13, and the elastic sleeve 20 is interference fit in the inner hole of the main shaft 10. The elastic sleeve 20 increases the friction between the drive shaft 13 and the main shaft 10 to ensure that the drive shaft 13 will not cause the limit plate 15 to accidentally slip out of the circular groove 14.
