[0029] The utility model is further described in conjunction with the following embodiments.

[0030] Example 1.

[0031] like Figure 1-2 As shown, a bone repair bone grinder for preventing nerve damage comprises a handheld end 1, a connecting strip 2 is arranged on the handheld end 1, a bone grinding mechanism 3 is arranged on the connecting strip 2, and an identification head 4 is installed at the end of the connecting strip 2.

[0032] When in use, the connecting strip 2 and the bone grinding mechanism 3 on the connecting strip 2 are extended to the position to be processed by operating the handheld part to perform the bone grinding operation. At the same time, the front and back of the bone grinding mechanism 3 can be confirmed by the identification head during use to prevent the bone grinder from being inverted due to negligence.

[0033] The bone grinding mechanism 3 includes a cylindrical bone grinder 5 and a special-shaped bone grinder 6. The cylindrical bone grinder 5 and the special-shaped bone grinder 6 are integrally connected. A smooth joint 7 is provided at one end of the cylindrical bone grinder 5 close to the identification head 4, and a smooth joint 7 is also provided at the special-shaped bone grinder 6 close to the handheld end 1.

[0034] The cylindrical bone grinder 5 and the special-shaped bone grinder 6 can be used together to perform bone grinding operations at multiple angles. Smooth joints 7 are provided at the connection points between the two ends of the cylindrical bone grinder 5 and the special-shaped bone grinder 6 and the connecting strip 2 to prevent sharp connection angles from causing unnecessary damage to nerves.

[0035] Both ends of the special-shaped bone grinder 6 and the cylindrical bone grinder 5 are provided with smooth surfaces 8, and a frosted surface 9 is provided between the two groups of smooth surfaces 8. The setting of the smooth surface 8 can prevent the frosted surface 9 from causing damage to the nerves when the bone grinding mechanism 3 is extended, and at the same time can reduce the probability of nerve damage during the bone grinding process.

[0036] The connecting strip 2 is a rectangular structure, and a smooth arc chamfer 10 is provided on the connecting strip 2. The rectangular and elongated design of the connecting strip 2 can facilitate the insertion of the bone grinding mechanism 3, and occupies a small space, thereby increasing the operating space.

[0037] The special-shaped bone grinder 6 is provided with an identification coating 11, which is arranged in a ring shape in the center of the special-shaped bone grinder 6. Since the bone grinding mechanism 3 is usually used in combination with an endoscope during operation, the setting of the identification coating can more quickly determine the position of the bone grinding mechanism 3 and the required bone grinding position during the bone grinding process, improve the reference capability with the endoscope, reduce the difficulty of operation, and improve the safety of the bone grinding process.

[0038] The central diameter of the handheld end 1 is smaller than the diameters at both ends. An anti-skid layer 12 is provided on the handheld end 1. The provision of the anti-skid layer 12 can enhance the friction force, thereby preventing the operator from slipping during the holding process and reducing the probability of nerve damage by the bone grinding mechanism 3.

[0039] During the production process, the combination of the special-shaped bone grinder 6 and the cylindrical bone grinder 5 in the bone grinding mechanism 3 can improve the comfort during the bone grinding process. At the same time, the smooth surfaces 8 arranged around the special-shaped bone grinder 6 and the cylindrical bone grinder 5 can prevent damage to bone nerves. At the same time, the smooth joint 7 and the connecting strip 2 with a circular chamfer 10 arranged at the connection between the connecting strip 2 and the bone grinding mechanism 3 can also prevent damage to nerves. The anti-slip layer 12 arranged on the handheld end 1 can prevent the operator from slipping during the holding process, reduce the chance of nerve damage, improve the operating effect and reduce the injury rate. At the same time, the application is small and convenient to manufacture, reducing economic consumption.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
