[0002] As orthopedic surgery progresses toward precision, the demand for drill bit accuracy is becoming increasingly stringent. Different bone locations (e.g., cancellous bone vs. cortical bone) and individual patient characteristics (e.g., osteoporosis in the elderly vs. density in the young) may require different drill bit types. For example, in fracture fixation surgery, a smaller diameter drill bit may be used to create a pilot hole before switching to a larger diameter drill bit to insert a screw or other fixation device.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The utility model provides Figure 1-6 A quick-replacement modular orthopedic drill bit shown includes a drill bit storage box 2 mounted on top of an electric bone drill 1, wherein a plurality of drill bits 3 are stored in the drill bit storage box 2;

[0032] Specifically, a sliding mounting slot 11 is provided on the top of the electric bone drill 1;

[0033] Reference Figure 5-6 The bottom of the drill bit storage box 2 is provided with a clamping block 21 that cooperates with the sliding installation groove 11, and a storage groove 22 is provided in the middle of the drill bit storage box 2. Positioning grooves 23 are provided on both sides of the storage groove 22. A storage tube 24 is provided in the positioning groove 23. The drill bit 3 is installed in the storage tube 24. A plurality of rotating holes 25 are also provided on the inner wall of the positioning groove 23. A limit assembly 4 is installed in the rotating hole 25. A magnetic strip 26 is provided on one side of the drill bit storage box 2;

[0034] Reference Figure 3A connecting portion 31 is provided at the tail of the drill bit 3, and magnetic heads 32 are provided at both ends of the connecting portion 31. A connecting sleeve 5 is also provided to match the connecting portion 31. The connecting sleeve 5 is installed inside the output end of the electric bone drill 1, and a magnetic seat 51 that cooperates with the magnetic head 32 is provided at the bottom end of the connecting sleeve 5. A shielding sleeve 52 is provided on the outside of the magnetic seat 51.

[0035] Reference Figure 6 The limiting assembly 4 includes a rotating shaft 41 installed in the rotating hole 25, an adjusting disk 42 is provided at one end of the rotating shaft 41, and a mounting disk 43 is provided at the other end. An arc-shaped spring piece 44 is fixed on the mounting disk 43, and the arc-shaped spring piece 44 limits the movement of the storage tube 24.

[0036] In this embodiment, the block 21 at the bottom of the drill bit storage box 2 is aligned with the sliding installation slot 11 at the top of the electric bone drill 1, and then the drill bit storage box 2 is slid into place along the sliding installation slot 11. This installation method is simple and convenient, and allows the drill bit storage box 2 to be stably installed on the electric bone drill 1.

[0037] In this embodiment, the storage tube 24 is placed in the positioning groove 23. Since the width of the storage tube 24 is smaller than the width of the positioning groove 23, it can be easily placed in. At the same time, the distance between each set of limiting components 4 on the same side can accommodate at least a single storage tube 24, and the arc-shaped spring piece 44 in the limiting component 4 is fixed on the rotating shaft 41 through the mounting plate 43, and the rotating shaft 41 is installed in the rotating hole 25. When the storage tube 24 is placed in the positioning groove 23, the arc-shaped spring piece 44 will limit the movement of the storage tube 24, ensuring that the storage tube 24 is stably placed in the positioning groove 23. The drill bit 3 is placed in the storage tube 24. Since the inner diameter of the storage tube 24 is larger than the outer diameter of the middle part of the drill bit 3, the drill bit 3 can be smoothly placed in the storage tube 24 and is protected to a certain extent in the storage tube 24. When the drill bit 3 is not in use, the magnetic head 32 at one end of the connecting portion 31 thereof will be attached to the magnetic strip 26 on one side of the drill bit storage box 2 , thereby preventing the magnetic head 32 from absorbing other metal objects and avoiding interference with the storage of the drill bit 3 .

[0038] Specifically, the distance between each set of limiting components 4 on the same side should at least be sufficient to accommodate a single storage tube 24.

[0039] Specifically, the magnetic strip 26 fits the magnetic head 32 at one end of the connecting portion 31 , and the width of the storage tube 24 should be at least smaller than the width of the positioning slot 23 .

[0040] Specifically, the inner diameter of the storage tube 24 should be at least larger than the outer diameter of the middle portion of the drill bit 3 .

[0041] Specifically, the overall length of the connecting portion 31 does not exceed the inner depth of the shielding sleeve 52 , and the overall shape of the connecting sleeve 5 matches the overall shape of the connecting portion 31 .

[0042] In this embodiment, when a drill bit 3 is needed, the drill bit 3 is taken out of the storage tube 24, and then the connecting portion 31 of the drill bit 3 is inserted into the connecting sleeve 5 inside the output end of the electric bone drill 1. Since the overall length of the connecting portion 31 does not exceed the internal depth of the shielding sleeve 52, and the overall shape of the connecting sleeve 5 matches the overall shape of the connecting portion 31, and the magnetic heads 32 at both ends of the connecting portion 31 cooperate with the magnetic seat 51 at the bottom end of the connecting sleeve 5, under the action of magnetism, the drill bit 3 can be quickly and accurately installed on the electric bone drill 1. When the drill bit 3 needs to be replaced, it is only necessary to pull the old drill bit 3 out of the connecting sleeve 5, and then install the new drill bit 3 into the connecting sleeve 5 according to the above installation steps. The magnetic connection method makes this replacement process very fast, and since the outer sleeve of the magnetic seat 51 is provided with a shielding sleeve 52, it can prevent the external magnetic field from interfering with the magnetic connection, ensuring the stability of each connection between the drill bit 3 and the electric bone drill 1.

[0043] In this embodiment, the drill bit storage box 2 is installed on the electric bone drill 1 through the cooperation of the clamping block 21 and the sliding mounting groove 11. This installation method can ensure that the drill bit storage box 2 will not shake or fall off easily during use, providing a stable environment for the storage of the drill bit 3. The installation process is simple and does not require complicated tools or operations. The doctor or operator can quickly complete the installation of the drill bit storage box 2, saving preparation time. The storage tube 24 provides an independent storage space for the drill bit 3, and is stably placed in the positioning groove 23 by the limit assembly 4, effectively preventing the drill bit 3 from being damaged by collision, friction, etc. during storage. At the same time, the protection of the magnetic head 32 by the magnetic strip 26 also avoids damage to the magnetic head 32 due to the adsorption of foreign objects. Multiple drill bits 3 can be stored in the drill bit storage box 2 in an orderly manner. Through the design of the positioning groove 23 and the storage tube 24, the position of each drill bit 3 is relatively fixed, which is convenient for searching and management.

[0044] In this embodiment, the magnetic connection between the drill bit 3 and the connecting sleeve 5 allows for extremely rapid installation and replacement. This rapid replacement capability can significantly improve work efficiency during urgent medical procedures or in situations where the drill bit 3 requires frequent replacement. The shape matching and magnetic connection between the connecting portion 31 and the connecting sleeve 5 ensures accurate installation of the drill bit 3 onto the electric bone drill 1. Furthermore, the shielding sleeve 52 prevents interference from external magnetic fields, ensuring a stable connection and preventing the drill bit 3 from becoming loose or poorly connected during use.

[0045] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
