[0002] With the continuous advancement of medical technology, medical devices are increasingly widely used in surgery and treatment. However, during use, especially in the surgical environment, medical devices are susceptible to microbial contamination, leading to postoperative infections and complications. To improve the safety and effectiveness of medical devices, the research and application of antibacterial coatings have gradually become a hot research area. Antibacterial coatings can effectively inhibit or kill pathogenic bacteria, reduce the risk of infection, and improve the durability and functional stability of devices. Research on antibacterial coatings for medical device saw blades mainly focuses on selecting suitable antibacterial materials and their coating processes to ensure the durability and antibacterial effect of the coating. Common antibacterial materials include silver ions, copper-based alloys, and various organic antibacterial agents. These materials have excellent antibacterial properties and can effectively adhere to the saw blade surface, thus forming a durable protective layer.

[0003] During the use of medical saw blades, since they come into direct contact with the patient's tissues during surgery, bacteria may attach to and multiply on their surface if there is no proper antibacterial treatment, thus increasing the risk of infection. Utility Model Content

The fixed restraint plate 203 will not move when touched. The bottom of the restraint plate 203 presses down on the tops of the two coating plates 204, preventing the coating plates 204 from sliding upwards. Symmetrical coating plates 204 are fixedly fitted onto the annular sidewall of the fixed shaft 201. The two coating plates 204 are located on either side of the right end of the saw blade 104, and a coating soft plate 205 is installed on the sidewall of each of the two coating plates 204. The coating soft plate 205 and the coating... When the two coating plates 205 are in contact, they will not wear out. The side walls of the two coating plates 205 are in contact with the two sides of the coating 105 respectively. During the rotation of the saw blade 104 and the coating 105 with the antibacterial liquid, the side walls of the two coating plates 205 will spread the antibacterial liquid evenly on the saw blade 104 and the coating 105. The bottom plate 3 is fixedly installed at the bottom of the support frame 1, and universal wheels are installed at the four corners of the bottom. Universal wheels are installed at the bottom of the bottom plate 3 to facilitate the movement of the entire device.

[0025] The support frame 1 has a through-cutting groove 101 in the middle of its upper end, and the lower end of the saw blade 104 passes through the cutting groove 101. A base 102 is fixedly installed in the rectangular groove of the support frame 1, and a groove is provided at the upper end of the base 102. Side plates are fixedly installed on both sides of the base 102, and through bolts are inserted at both ends of the side plates. The bolts on the side plates of the base 102 are rotated and inserted into the threaded grooves of the support frame 1 to fix and restrict the base 102. When the base 102 is touched, it will not... The movement will occur, so that the base 102 can stably support the motor 103. The motor 103 is fixedly installed in the groove of the base 102. When the motor 103 is started, the saw blade 104 on the shaft will rotate rapidly. The rotating saw blade 104 cuts the object with its upper end. A retaining ring is fixedly fitted at the rear end of the motor 103 shaft. The saw blade 104 is installed on the shaft of the motor 103.

The machine will rotate, and the two pumps 303 will start to draw the antibacterial liquid from the antibacterial liquid tank 301 up through the suction pipe 304. Then it will be discharged from the nozzle of the drain pipe 305. At this time, the discharged antibacterial liquid will fall on the coating 105 on both sides of the saw blade 104, applying a layer of antibacterial liquid to the surface of the lower coating 105, thereby protecting the surface of the coating 105 on both sides. The drain pipes 305 are fixedly installed at the opposite ends of the two pumps 303, and the head of the drain pipe 305 is equipped with a conical nozzle. The nozzle on the drain pipe 305 is aimed at the lower end of the coating 105.

[0027] Example 2, based on Example 1, such as Figure 1 and Figure 4 As shown, side plates are fixedly installed on both sides of the base 102, and through bolts are inserted at both ends of the side plates. Remove the side plates and bolts on the base 102, and then fix the base 102 to the support frame 1 to stabilize and restrict the base 102. In this way, the base 102 will not tilt when touched, avoiding the bolts from loosening and failing to stabilize the base 102 after long-term use, and also saving the cost of parts.

[0028] The working principle of this embodiment is as follows: When in use, the saw blade 104 on the shaft of the start motor 103 will rotate rapidly. The upper end of the rotating saw blade 104 cuts the object. During the cutting process, the coating 105 on the saw blade 104 will rotate. The two pumps 303 are started and the antibacterial liquid in the antibacterial liquid tank 301 is drawn up through the liquid extraction pipe 304 and then discharged from the nozzle of the drain pipe 305. At this time, the discharged antibacterial liquid will fall on the coating 105 on both sides of the saw blade 104, applying a layer of antibacterial liquid to the surface of the lower coating 105, thereby protecting the surface of the coating 105 on both sides. The side walls of the two coating soft plates 205 are respectively attached to the two sides of the coating 105. During the rotation of the saw blade 104 and the coating 105, the side walls of the two coating soft plates 205 will evenly coat the antibacterial liquid on the saw blade 104 and the coating 105.
