Background
Saw blades have been widely used in orthopedic surgery as a basic tool, but electric bone saws have not been fully optimized in the application process. Through the research on the cutting mechanism of the saw blade and the bone tissue, the poor saw blade generates a high temperature of about 200 degrees Fahrenheit and about 93 degrees Celsius when the bone tissue is cut, so that the high temperature can damage the bone tissue and cause the thermal damage of the bone tissue. At present, the bone saw generally has the following four problems in an operation scene:
1. the temperature during the bone sawing process cannot be guaranteed not to exceed the temperature causing the thermal injury of the bone tissue, namely, the thermal injury of the bone tissue cannot be guaranteed not to be generated during the operation process.
2. The manual work can not accurately judge whether the saw blade of the bone saw is well installed.
3. The manual work can not accurately judge whether the bone saw has faults in the operation process.
4. The video in the operation process can not be recorded, and other video recording equipment is required to be added for recording the video in the operation.

Further, the temperature of the heat injury of the bone formation bone tissue is an artificial set value, and the temperature of the sawn bone is a real-time measured value.
Further, when the obtained vibration information has no larger deviation with the no-load operation vibration information of the bone saw without faults, the installation of the saw blade of the bone saw is finished; if the bone saw blade has large deviation, the bone saw blade is replaced again, the bone saw can be judged to have problems when the vibration information has large deviation after the bone saw blade is replaced for 3 times, and the operation is performed after the bone saw is replaced.

Furthermore, the reason for adjusting the rotating speed of the bone saw motor is that the rotating speed of the bone saw motor is too high, and the temperature of the bone to be sawn is too high, so that the rotating speed of the bone saw motor needs to be reduced to keep the temperature below the temperature for forming the thermal injury of the bone tissue; on the contrary, the rotating speed of the bone saw motor is slow, and the temperature of the bone to be sawed is much lower than the temperature of the bone tissue to be formed with thermal injury, so that the rotating speed of the bone saw motor can be properly increased.
Further, the basis for judging whether the bone saw has a fault according to the vibration information is that the saw blade vibration information of the normal bone sawing state corresponding to the age and the bone density of the patient in the database is acquired before the operation, the saw blade vibration information is compared in real time in the operation process, if the deviation between the saw blade vibration information and the normal bone sawing information is large, the possibility that the bone saw has a problem is displayed, and the operation is performed after the bone saw is checked or the saw blade of the bone saw is replaced; if the deviation of the saw blade vibration information and the normal bone sawing information is extremely large or the saw blade of the bone saw is replaced for 3 times to ensure that the saw blade of the bone saw still has large deviation after being completely installed, the problem of the bone saw is displayed, and the operation is carried out after the bone saw is replaced.
Furthermore, the temperature and vibration information of the bone saw in the working process can be stored, the two data in the operation can be analyzed after the operation, and the range of adjusting the rotating speed of the bone saw motor in the operation can be optimized according to the information.
Furthermore, the bone sawing process video is recorded and stored, and other operators can learn the bone sawing process video conveniently.
