[0025] In order to make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0026] The present utility model provides an opening device for a medical bone plate. Through the mutual cooperation of the provided opening installation component and the auxiliary opening component, after the bone plate is opened, the entire bone plate placement groove is automatically pneumatically impacted, so as to stably open the hole for the next placed bone plate, avoid the influence of debris on the accuracy of bone plate hole opening, and eliminate the need for the user to spend time cleaning, facilitating efficient hole opening.

[0027] Figures 1 - 4 Shown is a schematic diagram of the overall structure of an embodiment of an opening device for a medical bone plate of the present utility model. Please refer to Figures 1 - 4 , the main structures of this embodiment include: an opening installation component and an auxiliary opening component.

[0028] The opening installation component is used for the installation and use of the opening device. Specifically, the opening installation component includes a base plate 11 provided, a support frame 12 fixed on the top surface of the base plate 11, a concave mounting frame 13 connected to the support frame 12, a first rotating shaft 14 passing through the concave mounting frame 13, a handle 15 connected to the first rotating shaft 14, a second rotating shaft 16 passing through the handle 15, a U-shaped connecting frame 17 connected to the second rotating shaft 16, a guide rod 18 movably connected to the end of the U-shaped connecting frame 17, and a driving motor 19 provided at the end of the guide rod 18;

[0029] During specific use, the user pulls the handle 15 with their hand. The handle 15 rotates through the first rotating shaft 14. At this time, the handle 15 rotates downward and pushes the U-shaped connecting frame 17. The two ends of the U-shaped connecting frame 17 are movably connected. At this time, the U-shaped connecting frame 17 can push the guide rod 18 downward, and the guide rod 18 drives the drill bit 22 to move downward, and then the hole can be drilled.

[0030] The auxiliary hole-drilling assembly is used to assist in hole-drilling to avoid the influence of hole-drilling debris on the next bone plate hole-drilling. Specifically, the auxiliary hole-drilling assembly includes a transmission shaft 21 connected to the output end of the driving motor 19, a drill bit 22 connected to the end of the transmission shaft 21, a long strip chute 23 opened on the top surface of the base plate 11, a slider 24 clamped into the long strip chute 23, a moving plate 25 connected to the slider 24, a bone plate placement groove 26 opened on the top surface of the moving plate 25, an air inlet cavity 28 located inside the moving plate 25, a threaded pipe 27 communicated with the air inlet cavity 28, a ventilation pipe 29 connected to the threaded pipe 27, and air outlet holes 261 opened on the inner side wall of the bone plate placement groove 26;

[0031] During specific use, the user places the bone plate to be drilled in the bone plate placement groove 26 and pushes the moving plate 25. The moving plate 25 drives the slider 24 to slide horizontally in the long strip chute 23 until the bone plate to be drilled moves to directly below the drill bit 22. At this time, the user uses a threaded long rod to penetrate the edge of the moving plate 25 for locking. At this time, the user pulls the handle 15 with their hand. The handle 15 rotates through the first rotating shaft 14. At this time, the handle 15 rotates downward and pushes the U-shaped connecting frame 17. The two ends of the U-shaped connecting frame 17 are movably connected. At this time, the U-shaped connecting frame 17 can push the guide rod 18 downward, and the guide rod 18 drives the drill bit 22 to move downward. The driving motor 19 drives the drill bit 22 to rotate for hole-drilling operation. When the hole-drilling is completed and the bone plate in the bone plate placement groove 26 is taken out, at this time, the external air compressor injects compressed air into the air inlet cavity 28 through the ventilation pipe 29 and the threaded pipe 27. Finally, the gas quickly sprays out through the air outlet holes 261. The distributed air outlet holes 261 quickly blow away the residues in the entire bone plate placement groove 26. In this way, when the next bone plate is placed, the flatness of the bone plate is ensured, thereby ensuring the accuracy of the bone plate hole-drilling and avoiding problems such as inclined hole-drilling and inaccurate hole-drilling.

[0032] Furthermore, through the set auxiliary hole-drilling assembly, the hole-drilling position can be pre-indicated to avoid the problem that the hole-drilling position is prone to deviation, which is convenient for the user to drill holes accurately and quickly. Specifically, it further includes an indication assembly. The indication assembly includes an installation cylinder 31 arranged outside the driving motor 19, an installation groove 32 opened on the bottom surface of the installation cylinder 31, and an infrared ray lamp 33 arranged in the installation groove 32;

[0033] During specific use, three mounting cylinders 31 are provided, and a corresponding infrared ray lamp 33 is provided in each mounting cylinder 31. The three infrared ray lamps 33 are inclined, and the light rays emitted by the three infrared ray lamps 33 converge at a point. In this way, when the drill bit 22 moves downward, the point where the light rays converge is indicated, and the converging light spot is the landing position of the drill bit 22, facilitating accurate hole opening.

[0034] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
