AI Technical Summary
Traditional nostril periosteal peelers are difficult to effectively peel off the periosteal when the internal operating space of the nostrils are small, and they need to frequently replace the clips and strippers, which makes it difficult to operate.
A nostril periosteal peeling assembly is designed, including a handle, a stripping shovel, a rotary handle and a clip. Through the dual functions of the elastic rotation of the rotary handle and the clamping, the periosteum is quickly and efficiently stripped in a narrow space.
Through dual-function clips and stripping shovels, the assembly can quickly and effectively peel off the periosteum in a narrow space inside the nostril, reducing operational difficulty and improving work efficiency.

Description
Technical Field
[0001] The utility model relates to the field of plastic surgery instruments, in particular to a nasal periosteum stripping component. Background Art
[0002] Maxillary ASO surgery, nasal alignment and other surgeries often require the peeling of the periosteum from the nostrils. Since the periosteum is very densely attached to the bone surface, tools are needed to assist in peeling the periosteum. Traditionally, a shovel-shaped peeler or blade is used to peel the periosteum, but the operating space inside the nostril is small, and clamps need to be frequently used to adjust the position of the peeled periosteum. The peeler and clamps are frequently replaced, making the operation difficult. Utility Model Content
[0003] The utility model aims to solve the following problems existing in the prior art: conventionally, a shovel-shaped stripper or a blade is used to strip the periosteum, but the operating space inside the nostril is small, and a clamp needs to be frequently used to adjust the position of the stripped periosteum. The stripper and the clamp are frequently replaced and used, which makes the operation more difficult.
[0004] In order to solve the problems existing in the prior art, the utility model provides a nasal periosteum stripping assembly, comprising a handle;
[0005] A stripping shovel, which is arranged at the front end of the handle;
[0006] A rotating handle, a groove is provided on the surface of the handle, the rotating handle is elastically rotated in the groove by a torsion spring, and the rear end of the rotating handle has a curved portion protruding from the surface of the handle;
[0007] A clip is fixed at the front end of the rotating handle, and a receiving groove for receiving the clip is provided on the surface of the stripping shovel.
[0008] Preferably, a stop column is fixed in the strip groove, and the stop column blocks the elastic rotation of the turning handle.
[0009] Preferably, the thickness of the stripping shovel gradually decreases from the center to the edge, and the stripping shovel is in an arc shape.
[0010] Preferably, the bottom surface of the clip has rough lines, the front edge of the clip is semicircular, and when the clip is placed in the receiving groove, the surface of the clip is flush with the surface of the stripping shovel.
[0011] Preferably, the rear end of the handle has an expanded diameter portion, and the surface of the expanded diameter portion is provided with anti-slip grooves.
[0012] Compared with the related art, the nasal periosteum stripping assembly provided by the utility model has the following beneficial effects:
[0013] The utility model controls the rotation of the clip by pressing the rotating handle, so that the clip can be attached to the surface of the stripping shovel to form a completed plane for stripping the periosteum. When the clip is tilted, it cooperates with the stripping shovel to clamp the periosteum. The dual functions are used in a coordinated manner, which is convenient for quickly stripping the periosteum in the narrow space of the nostril. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0022] like Figure 1 , Figure 2 As shown, the front and rear ends of the cylindrical handle 1 are integrally fixed with the stripping shovel 2 and the enlarged diameter portion 11, respectively. The surface of the enlarged diameter portion 11 is provided with anti-slip grooves to increase the hand-holding stability. The surfaces of the handle 1 and the enlarged diameter portion 11 are provided with grooves 12, which extend to the front end of the handle 1.
[0023] like Figure 3 As shown, the stripping shovel 2 is elliptical in shape, and the thickness of the stripping shovel 2 gradually decreases from the center to the edge, so that the edge of the stripping shovel 2 is sharp, and the left and right ends of the stripping shovel 2 are upturned, so that the stripping shovel 2 forms an arc shape, and a receiving groove 21 is formed through the surface of the stripping shovel 2, and the receiving groove 21 is connected to the strip groove 12;
[0024] like Figure 2As shown, the handle 4 is made of a round rod, and the handle 4 is placed in the groove 12. The front end of the handle 4 is elastically rotated to connect the front end of the groove 12 through a torsion spring, and the rear end of the handle 4 has a bent portion 41 that bends upward and protrudes from the surface of the handle 1. The clip 3 is fixed to the front end of the handle 4, and the clip 3 is adapted to the shape of the receiving groove 21.
[0025] like Figure 1 , Figure 4 As shown, the front edge of the clip 3 is semicircular, and when the clip 3 is placed in the receiving groove 21, the surface of the clip 3 is flush with the surface of the stripping shovel 2;
[0026] A stopper 5 is fixed in the strip groove 12, and the stopper 5 blocks the elastic rotation of the rotating handle 4, so that the clip 3 fits in the receiving groove 21, and the stripping shovel 2 forms a complete surface. When performing the stripping of the internal periosteum of the nostril, the enlarged diameter portion 11 is held, and the stripping shovel 2 is inserted from the incision position, and the periosteum is separated by the sharp edge of the stripping shovel 2. When the stripped periosteum needs to be clamped and adjusted, it is only necessary to withdraw the stripping shovel 2 to the incision position, and the hand presses the curved portion 41 to sink into the strip groove 12, and the rotating handle 4 overcomes the elastic force and rotates, so that the clip 3 is rotated out of the receiving groove 21, and the stripping shovel 2 is placed on the inner side of the periosteum, and the clip 3 is placed on the outer side of the periosteum. The curved portion 41 is released, and the rotating handle 4 is elastically rotated, and the clip 3 and the stripping shovel 2 clamp the periosteum, and then the periosteum is adjusted;
[0027] like Figure 5 As shown, the bottom surface of the clip 3 has rough texture, so that the clip 3 and the stripping shovel 2 can stably clamp the periosteum and prevent slipping.
