[0002] Pneumatic tools for medical devices are mainly used in operating rooms or medical equipment maintenance, and can effectively improve work efficiency and safety. The advantage of pneumatic tools is that they can be operated without direct contact, avoiding the risk of cross infection. In addition, the power and speed of pneumatic tools can be adjusted, which is convenient for precise control of operating force and precision, and is very suitable for scenarios such as medical equipment maintenance and surgical operations. Specifically, there are many kinds of pneumatic tools for medical devices, such as pneumatic drills, pneumatic grinders, pneumatic saws, etc. These tools can be used for cutting, grinding, drilling and other operations during surgery, and can be used for tasks such as disassembly, installation, and maintenance in medical equipment maintenance.

[0003] Some existing medical devices have some problems. Since pneumatic tools use compressed air as power, they will generate loud noise, which may cause discomfort to operators and medical subjects. Operators are prone to symptoms such as headaches, deafness, hearing loss, insomnia, etc. when exposed to high noise environments for a long time, and may even have adverse psychological effects such as anxiety and irritability. When medical subjects are undergoing medical operations, if the noise in the surrounding environment is too loud, it may cause emotional reactions such as uneasiness, fear, anxiety, etc., affecting the treatment effect. For this reason, we have proposed a pneumatic tool for medical devices. Utility Model Content
