[0034] like Figures 1 to 5As shown, an embodiment of the present invention provides a periosteal stripper for nose plastic surgery and repair, comprising a handle 1, a telescopic rod 2 is sleeved in the handle 1, and a stripping head 5 is fixedly connected to one end of the telescopic rod 2 extending to the outside of the handle 1, and a sleeve groove 10 adapted to the shape of the telescopic rod 2 is opened in the handle 1. The sleeve groove 10 opened in the handle 1 provides an assembly area for the telescopic rod 2, allowing the telescopic rod 2 to be telescopically and slid in the handle 1, thereby adjusting the length of the telescopic rod 2 extending from the handle 1 to meet the usage requirements in different scenarios, and a paddle 3 is symmetrically installed on the outside of the handle 1. The handle 1 is the main gripping area of ​​the entire device. The doctor can drive the telescopic rod 2 and the stripping head 5 to produce corresponding displacement by gripping the handle 1 to perform a periosteum stripping operation; a locking assembly is used to fix the relative position between the telescopic rod 2 and the handle 1, and the locking assembly is connected to the paddle 3. The locking assembly is used to lock the telescopic rod 2 after it is telescopically adjusted in the handle 1, so that the relative position between the adjusted telescopic rod 2 and the handle 1 remains fixed, ensuring the stability of the entire device during the periosteal stripping operation.

[0035] like Figures 1 to 3 As shown, a semicircular groove is provided on the telescopic rod 2, and the semicircular groove extends to the end of the telescopic rod 2 away from the stripping head 5. The semicircular groove on the telescopic rod 2 can increase the contact area between the telescopic rod 2 and the sleeve groove 10 after the telescopic rod 2 is sleeved in the sleeve groove 10, thereby enhancing the stability of the connection between the telescopic rod 2 and the handle 1. A pinching groove 4 is provided at one end of the telescopic rod 2 close to the stripping head 5, and the pinching groove 4 and the outside of the handle 1 are both provided with evenly distributed friction lines. The pinching groove 4 provided on the telescopic rod 2 can facilitate the doctor to adjust the telescopic rod 2. When adjusting, the pinching groove 4 area can be pinched. The pinching groove 4 is an arc-shaped groove structure, and its shape is adapted to the shape of the finger, which can increase the fit effect with the doctor's finger and increase the contact between the doctor's finger and the doctor's finger through the friction lines on the pinching groove 4. The contact area increases the friction between the doctor's fingers and the telescopic rod 2, which plays an anti-slip role during the telescopic adjustment of the telescopic rod 2. The friction lines on the handle 1 are similar, which play an anti-slip role when holding the handle 1 to perform the periosteum stripping operation. A guide surface 9 is provided at the end of the telescopic rod 2 away from the stripping head 5. The guide surface 9 provided at the end of the telescopic rod 2 away from the stripping head 5 makes the area at the end smaller than the area at the entrance of the sleeve groove 10, making the assembly operation of the telescopic rod 2 into the handle 1 simple and convenient, and easy to replace the stripping head 5 on the telescopic rod 2 after use. The handle 1 has a hollow structure. The hollow structure of the handle 1 can reduce the weight of the handle 1 without affecting the overall structural strength of the handle 1 too much, thereby reducing the weight of the entire device and making it more labor-saving for the doctor to use the device.

[0036] like Figure 3 and Figure 5As shown, the cross-section of the paddle 3 is trapezoidal, and an arc-shaped groove is provided in the middle of the paddle 3. The outside of the paddle 3 is provided with evenly distributed friction patterns. Squeezing the paddle 3 can drive the locking assembly to work. The trapezoidal structure of the cross-section of the paddle 3 forms an inclined surface on the top of the paddle 3. When the doctor's thumb presses the paddle 3, the pressing force can be decomposed through the inclined surface structure, thereby driving the paddle 3 to move toward the outside of the handle 1, and then the paddle 3 drives the locking assembly to work.

[0037] like Figures 2 to 5 As shown, the locking assembly includes a connecting plate 6 fixedly connected to the bottom of the paddle 3, the bottom end of the connecting plate 6 extends into the handle 1 and is fixedly connected to a movable piece 15, and the movable piece 15 is fixedly connected to evenly distributed fixing columns 16. The outer side of the telescopic rod 2 is provided with a fixing hole 8 that is adapted to the shape of the fixing column 16. When the paddle 3 is pressed so that the paddle 3 pulls the locking assembly to work, the paddle 3 drives the movable piece 15 to move in the handle 1 through the transmission of the connecting plate 6, and drives the fixing column 16 to withdraw from the fixing hole 8 on the telescopic rod 2, releasing the limit lock on the telescopic rod 2, allowing the telescopic rod 2 to be telescopic in the handle 1. When no force is applied to the paddle 3, the fixing column 16 on the movable piece 15 is embedded in the fixing hole 8 on the telescopic rod 2, locking the telescopic rod 2, thereby ensuring the stability of the telescopic rod 2 in the fixed state.

[0038] The sleeve groove 10 is provided with a through circular hole 12 that is adapted to the shape of the fixed column 16, and the outside of the handle 1 is provided with a sliding groove 11 that is adapted to the shape of the connecting plate 6. The through circular hole 12 is connected to the sleeve groove 10. The through circular hole 12 provided on the sleeve groove 10 can facilitate the passage of the fixed column 16 on the movable piece 15. The telescopic rod 2 is sleeved in the sleeve groove 10. When the locking assembly locks the telescopic rod 2, the movable piece 15 is attached to the outside of the sleeve groove 10, and the fixed column 16 passes through the through circular hole 12 on the sleeve groove 10 and is embedded in the fixing hole 8 on the telescopic rod 2.

[0039] A fixed plate 13 is fixedly connected to the inner side wall of the handle 1. The position of the fixed plate 13 corresponds to the position of the movable plate 15, and the fixed plate 13 and the movable plate 15 are connected by a deformable plate 14. The fixed plate 13 and the movable plate 15 have the same thickness. The deformable plate 14 is wavy and has a thickness less than that of the fixed plate 13 and the movable plate 15. When the paddle 3 is displaced, the movable plate 15 is driven to displace in the handle 1 by the transmission of the connecting plate 6. When the movable plate 15 is displaced, it squeezes the deformable plate 14. The thickness of the deformable plate 14 is thinner and weaker than that of the fixed plate 13 and the movable plate 15, making it more susceptible to deformation when subjected to external force. Therefore, the squeezing of the movable plate 15 can cause the deformable plate 14 to bend and deform, allowing the deformable plate 14 to accumulate elastic force. After the squeezing force on the paddle 3 is removed, the deformable plate 14 can drive the movable plate 15 to return to its original position under the action of its own elastic force, allowing the locking assembly to return to the locked state.

[0040] like Figures 4 and 5 As shown, the movable piece 15 is fixedly connected to the limiting piece 7 at a side away from the fixed column 16, and the fixed piece 13 is fixedly connected to a limiting sleeve 17 corresponding to the position of the limiting piece 7 at a side close to the movable piece 15. The limiting piece 7 is slidably sleeved in the limiting sleeve 17. The ends of the movable piece 15 and the fixed piece 13 away from the deformation piece 14 are in an open structure. In order to avoid misalignment during the displacement of the movable piece 15, a limiting piece 7 and a limiting sleeve 17 are provided to limit the end of the movable piece 15 in the open structure during the displacement process, provide guidance for the displacement of the movable piece 15, and ensure the stability of the locking assembly during operation.

[0041] The working principle of the technical solution provided by the utility model is as follows:

[0042] When in use, one hand holds the handle 1 and squeezes the paddle 3 with the thumb of the hand holding the handle 1. After the paddle 3 is squeezed, the movable piece 15 is driven to displace in the handle 1 through the transmission of the connecting plate 6. When the movable piece 15 is displaced, it slides along the guide of the limiting piece 7 and the limiting sleeve 17. The movable piece 15 drives the deformable piece 14 to bend and deform, and drives the fixing column 16 to withdraw from the fixing hole 8 on the telescopic rod 2, thereby releasing the limit lock on the telescopic rod 2.

[0043] After the telescopic rod 2 is unlocked, use the other hand that is not holding the handle 1 to pinch the pinching groove 4 area on the telescopic rod 2 and pull the telescopic rod 2, so that the telescopic rod 2 can be telescoped in the handle 1. After adjusting the extended length of the telescopic rod 2 from the handle 1 to an appropriate length, release the thumb that squeezes the paddle 3, and the deformable piece 14 drives the movable piece 15 to reset due to its own elasticity. The movable piece 15 drives the fixed column 16 again to be inserted into the fixed hole 8 on the outside of the adjusted telescopic rod 2, and the telescopic rod 2 can be locked again. After that, the handle 1 can be held to drive the stripping head 5 through the telescopic rod 2 to perform the periosteal stripping work of nose plastic surgery repair, completing the entire use process of the nose plastic surgery repair periosteal stripper.

[0044] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
