[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 2As shown in the figure, a drilling device for orthopedic implant screws according to an embodiment of the present invention includes a motor 4, a top cover 5 mounted on the top of the motor 4, a slide rail inside the motor 4, a drilling machine 1 slidably mounted inside the slide rail, a drill bit 2 mounted on the bottom of the drilling machine 1, a protective sleeve 3 mounted on the bottom of the motor 4, the protective sleeve 3 enclosing the drilling machine 1, and a fixing structure inside the protective sleeve 3. During operation, the doctor holds the protective sleeve 3 and adjusts the position of the drilling machine 1 by adjusting the fixing structure inside the protective sleeve 3 in conjunction with the slide rail inside the motor 4 to adjust the drilling machine 1 to a comfortable position. The motor 4 is then started, and the motor 4 drives the bottom tip of the drilling machine 1 to rotate, which in turn drives the drill bit 2 to rotate, drilling the required location. Through the above structure, the drilling depth of the device can be freely adjusted, and the addition of an anti-slip structure reduces the doctor's slippage during use, increasing the practicality of the device.

[0026] like Figure 3As shown, the motor 4 has a second rotating shaft 21 connected to its side wall. A second irregularly shaped part 29 is rotatably mounted on the other end of the second rotating shaft 21.

The second rotating shaft 21 is rotatably mounted on the other end of the second rotating shaft 21. The first irregularly shaped part 27 is rotatably mounted at one end. A second rotating shaft 21 is rotatably mounted on the circular sidewall of the first irregularly shaped part 27. An irregularly shaped connector 26 is rotatably mounted on the other end of the second rotating shaft 21. The second rotating shaft 21 is rotatably mounted on the bottom of the irregularly shaped connector 26. A second telescopic rod 25 is rotatably mounted on the second rotating shaft 21. A connecting block 24 is fixedly mounted on the bottom of the second telescopic rod 25. Second fixing blocks 22 are provided on both sides of the connecting block 24. Circular openings are provided on the sidewalls of the second fixing blocks 22 and the connecting block 24. A connecting shaft 23 is provided inside the openings. A base 12 is fixedly connected to the bottom of the second fixing block 22. During operation, the motor 4 is powered by the second rotating shaft 21. Connected to the side wall of the second irregular part 29, the second rotating shaft 21 is rotated to allow the motor 4 to rotate freely. The second rotating shaft 21 on the side wall of the second irregular part 29 allows the second irregular part 29 to rotate freely, extending the third telescopic rod 28. This, combined with the second irregular part 29, provides the motor 4 with better freedom of movement. Rotating the second rotating shaft 21 at the other end of the third telescopic rod 28 allows it to rotate freely, further enhancing its flexibility. Rotating the second rotating shaft 21 between the irregular connector 26 and the first irregular part 27 allows the first irregular part 27 to change the position of the third telescopic rod 28. Rotating the irregular connector... 26. The second rotating shaft 21 between the second telescopic rods 25 allows the irregularly shaped connector 26 to change the position of the first irregularly shaped part 27, stretches the second telescopic rod 25, and allows the position of the irregularly shaped connector 26 to change. The rotating connecting block 24, in conjunction with the connecting shaft 23, allows the position of the second telescopic rod 25 to change. The second fixing block 22 is fixed to the base 12 to fix the entire device. Through the above structure, the addition of a robotic arm not only greatly reduces the labor intensity of doctors and reduces their fatigue during long surgeries, but also reduces the impact of fatigue on surgical outcomes, increasing the practicality and flexibility of the device.

[0027] like Figure 4As shown, the drill bit 2 has a U-shaped groove inside, with conveying pipes 6 installed at both ends of the U-shaped groove. The conveying pipes 6 pass through the drilling machine 1, motor 4, and top cover 5 and are installed on both sides of the connecting pipe 7. The connecting pipe 7 is installed on the top of the base 12. The other end of the connecting pipe 7 is connected to the first water pump 8 and the second water pump 10. The first water pump 8 and the second water pump 10 are installed on the top of the base 12. During operation, by starting the first water pump 8, the first water pump 8 delivers coolant to the inside of the connecting pipe 7. The connecting pipe 7 delivers coolant to the conveying pipe 6, and the conveying pipe 6 delivers coolant to the inside of the drill bit 2. The coolant flows through... The coolant is transported through the U-shaped groove inside the drill bit 2 to the delivery pipe 6 at the other end. The delivery pipe 6 delivers the coolant to the connecting pipe 7, which in turn delivers the coolant to the second water pump 10. By starting the second water pump 10, the above process is reversed, which cools the heat generated by the drill bit 2 during drilling and makes efficient use of the coolant. Through the above structure, adding coolant to the device reduces the high heat generated during operation, which could lead to bone tissue necrosis and adversely affect the surgical outcome. It could even cause additional pain and recovery time for the patient, thus increasing the practicality of the device.

[0028] like Figures 1 to 2 As shown, the base 12 has mounting holes 13 fixed to its side. The mounting holes 13 have connecting grooves inside, which connect to the first telescopic rod 14. A circular opening is located at the top of the connection between the mounting holes 13 and the first telescopic rod 14, and a fixing bolt 30 is installed inside the opening. A first fixing block 15 is fixed to the other end of the first telescopic rod 14. A circular opening is located inside the first fixing block 15, and a first rotating shaft 18 is installed inside the opening. A knob 17 is fixed to the top of the first rotating shaft 18. The outer wall of the first rotating shaft 18 and the inner wall of the first fixing block 15 have the same threads. A movable block 19 is rotatably mounted on the bottom of the first rotating shaft 18. Two auxiliary stabilizing rods 16 are located on both sides of the first rotating shaft 18. The bottom is fixed to the movable block 19, and the auxiliary stabilizing rod 16 passes through the first fixed block 15. The above structure has four sets, with one at each end of the base 12. In operation, the device needs to be fixed on a table of different sizes. By stretching the first telescopic rod 14, the first fixed block 15 is moved to the required position. Rotating the knob 17 drives the first rotating shaft 18 to rotate. Through the threaded engagement, the movable block 19 is pulled up and clamped to the edge of the table. The device is fixed to the tabletop by the engagement of the four structures. Through the above structure, the device can be installed in more required positions, while improving the stability of the device during use and increasing the practicality and stability of the device.

[0029] like Figures 1 to 2As shown, the bottom of the first fixed block 15 is equipped with an anti-slip pad 20, and the top of the movable block 19 is equipped with an anti-slip pad 20. During operation, the anti-slip material of the anti-slip pad 20 enables the device to achieve better stability. Through the above structure, the device is better fixed, increasing the practicality of the device.

[0030] like Figures 1 to 2 As shown, the base 12 has a tray 11 on top, and there are two trays 11. During operation, the remaining necessary tools are placed on top of the trays 11.

[0031] like Figures 1 to 2 As shown, the first water pump 8 is equipped with a water inlet 9 on its top. During operation, the coolant is replaced and inspected through the water inlet 9. The above structure enables the coolant used in the device to be quickly inspected and replaced, improving the practicality of the device.

[0032] During operation, the doctor holds the protective sleeve 3 and adjusts the internal fixing structure of the protective sleeve 3, along with the internal slide rail of the motor 4, to adjust the position of the drilling machine 1. Once the drilling machine 1 is adjusted to a comfortable position, the motor 4 is started. The motor 4 drives the bottom tip of the drilling machine 1 to rotate, which in turn drives the drill bit 2 to rotate, drilling the required location. The motor 4 is connected to the side wall of the second irregular part 29 via the second rotating shaft 21. Rotating the second rotating shaft 21 allows the motor 4 to rotate freely. The second irregular part 29 can also rotate freely via the second rotating shaft 21 on its side wall, extending the third telescopic rod 28. By combining the second irregular part 29, the motor 4 gains greater freedom of movement. Rotating the second rotation shaft 21 at the other end of the third telescopic rod 28 allows the third telescopic rod 28 to rotate freely, further enhancing its flexibility. Rotating the second rotation shaft 21 between the irregular connector 26 and the first irregular part 27 allows the first irregular part 27 to change the position of the third telescopic rod 28. Rotating the second rotation shaft 21 between the irregular connector 26 and the second telescopic rod 25 allows the irregular connector 26 to change the position of the first irregular part 27. Stretching the second telescopic rod 25 allows the irregular connector 26 to change its position. Rotating the connecting block 24 engages the connecting mechanism. Shaft 23 allows the position of the second telescopic rod 25 to be changed. The second fixing block 22 is fixed to the base 12 to fix the entire device. By starting the first water pump 8, the first water pump 8 delivers coolant to the inside of the connecting pipe 7. The connecting pipe 7 delivers coolant to the delivery pipe 6. The delivery pipe 6 delivers coolant to the inside of the drill bit 2. The coolant is delivered through the U-shaped groove inside the drill bit 2 to the delivery pipe 6 at the other end. The delivery pipe 6 delivers coolant to the inside of the connecting pipe 7. The connecting pipe 7 delivers coolant to the second water pump 10. By starting the second water pump 10, the above process is reversed, causing the drill bit 2 to rotate. The heat generated during the drilling process is cooled, and the coolant is used efficiently. To fix the device on tables of different sizes, the first fixed block 15 is moved to the desired position by stretching the first telescopic rod 14. The knob 17 is rotated, which drives the first rotating shaft 18 to rotate. The moving block 19 is pulled up and clamped to the edge of the table through the threaded engagement. The device is fixed to the tabletop by the engagement of the four structures. The anti-slip material of the anti-slip pad 20 makes the device more stable. The remaining necessary tools are placed on top of the tray 11, and the coolant is replaced and checked through the water inlet 9.
