The basic principles defined in the following description of the present utility model can be used in other implementation schemes, deformation schemes, improvement schemes, equivalent schemes, and other technical schemes without departing from the spirit and scope of the present utility model.

[0028] Please refer to Figures 1-6 , an orthopedic clinical drilling device shown in the figure, includes a base 1 and a drill bit 8; the base 1 is made of high-strength stainless steel material, and the drill bit 8 is made of a medical alloy material with extremely high hardness. It also includes: an adjusting rod 2 installed on the base 1, the adjusting rod 2 is made of aluminum alloy material, and lightweight design is achieved on the premise of ensuring a certain strength, which is convenient for medical staff to flexibly adjust the position according to the surgical needs. An air cylinder 9 is installed outside the adjusting rod 2, and the specific model of the air cylinder 9 is selected according to the usage situation. The output end of the air cylinder 9 is fixedly connected with a slider 10. A slide rail 3 is installed outside the adjusting rod 2, and a limiting plate 4 is connected to the top of the slide rail 3. The slider 10 is slidably connected with the slide rail 3. The two cooperate with each other, which can not only guide the slider 10 to move horizontally along the adjusting rod 2 smoothly and accurately, but also prevent the slider 10 from slipping off accidentally, ensuring the safety and accuracy of the surgical operation. And an adjusting mechanism 5 installed outside the slider 10, the adjusting mechanism 5 is used to adjust the angle of the drill bit 8; and a moving part 6 installed on the adjusting mechanism 5, the moving part 6 is used to move the drill bit 8; and a rotating part 7 installed on the moving part 6, the rotating part 7 is used to assist the adjusting mechanism 5.

[0029] Further, the adjusting mechanism 5 includes a connecting plate 11, the connecting plate 11 is made of aviation aluminum alloy material, the connecting plate 11 is fixedly installed outside the slider 10, a limiting frame 13 is installed at the bottom of the connecting plate 11, through holes 19 are symmetrically opened on the limiting frame 13, and a servo motor 12 is installed outside the limiting frame 13. The servo motor 12 is the power core of the adjusting mechanism 5, and adopts high-resolution encoder feedback control technology. The internal winding is made of copper material with high temperature resistance and high conductivity, and the shell is made of aluminum alloy material with good heat dissipation. It can accurately control the rotation angle and speed of the output shaft. The output end of the servo motor 12 is fixedly connected with a screw rod 14 through a coupling. The screw rod 14 is made of high-quality alloy steel by grinding, with high surface hardness and high thread precision. The other end of the screw rod 14 is rotatably connected to the inner wall of the limiting frame 13 to ensure flexible and stable rotation.

[0030] Further, please refer to Figure 5, an external thread of the screw rod 14 is connected with a moving block 15. The moving block 15 is slidably connected with a guiding groove inside the limiting frame 13. The contact part between the guiding groove and the moving block 15 is treated with a wear-resistant coating with a low friction coefficient. An external part of the moving block 15 is fixedly connected with a long rod 16. The long rod 16 passes through a through hole 19 and is rotatably connected with a connecting rod 17. Self-lubricating spherical plain bearings are used at these rotating connection parts to reduce maintenance costs and movement resistance. One end of two connecting rods 17 away from the long rod 16 is rotatably connected with a mounting frame 18, and the mounting frame 18 is rotatably connected with the connecting plate 11.

[0031] Specifically: The moving component 6 includes a driving motor 20. The driving motor 20 is also selected as a motor with high-precision speed regulation performance and high shell protection level. The driving motor 20 is fixedly installed outside the mounting frame 18. An output end of the driving motor 20 is fixedly connected with a lead screw 21 through a coupling. The lead screw 21 is selected as a ball screw structure. The lead screw 21 is rotatably connected with an inner wall of the mounting frame 18. An external thread of the lead screw 21 is connected with a positioning block 22. A bottom of the positioning block 22 is fixedly connected with a connecting block 23. The positioning block 22 is slidably connected with the inner wall of the mounting frame 18. Driven by the lead screw 21, the positioning block 22 drives the connecting block 23 and subsequent components to achieve precise linear displacement, meeting the rapid adjustment requirements of the drill bit 8 at different planar positions.

[0032] In a preferred embodiment, according to Figure 1 , Figure 3 and Figure 6 shown, the rotating component 7 includes a fixed disk 24. The fixed disk 24 is fixedly connected with the connecting block 23. A rotating shaft 25 is rotatably connected inside the fixed disk 24. One end of the rotating shaft 25 is fixedly connected with a turntable 26. An external part of the turntable 26 and the drill bit 8 adopt a convenient quick-release connection structure, facilitating the rapid replacement of drill bits 8 with different specifications according to requirements during the operation (not shown in the figure). One end of the rotating shaft 25 away from the turntable 26 is fixedly connected with an adjusting cap 30. The surface of the adjusting cap 30 is designed with anti-slip patterns, facilitating the manual fine-tuning operation by medical staff.

[0033] Specifically, referring to Figure 3 and Figure 6As shown in the figure, a groove 32 is provided on the side of the turntable 26 close to the fixed disk 24. An elastic sheet 27 is installed inside the groove 32. The elastic sheet 27 is made of high-elastic stainless steel and undergoes a special heat treatment process to ensure that it can maintain stable elasticity under long-term repeated stress. The outer part of the elastic sheet 27 is rotatably connected with a steel ball 29. The steel ball 29 is made of high-hardness bearing steel, has a high surface finish, and rolls smoothly. A gasket 28 for limiting its position is provided outside the steel ball 29. The gasket 28 is made of wear-resistant rubber, which can not only effectively restrict the position of the steel ball 29 but also buffer the impact during rotation. A plurality of limiting holes 31 are evenly provided on the side of the fixed disk 24 close to the turntable 26. The diameter of the limiting holes 31 is the same as that of the steel ball 29. When the turntable 26 rotates to a specific angle, the steel ball 29 is clamped into the limiting holes 31 under the action of the elastic sheet 27, realizing precise angle fine adjustment and positioning of the turntable 26, that is, the drill bit 8, to meet the extremely fine surgical drilling angle requirements.

[0034] It should be noted that the driving cylinder 9, the servo motor 12, the transmission motor 20, etc. are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.

[0035] In this solution, the principle is as follows:

[0036] First, when starting the orthopedic clinical drilling device, first, the cylinder 9 is started according to a preset program or manually controlled by medical staff, and the slider 10 is pushed to move rapidly horizontally along the slide rail 3 of the adjusting rod 2, quickly positioning the drill bit 8 approximately above the surgical site.

[0037] Then, the servo motor 12 is started to drive the screw rod 14 to rotate. Due to the threaded transmission relationship between the screw rod 14 and the moving block 15, and the restriction of the moving block 15 by the guiding groove of the limiting frame 13, the moving block 15 can only move linearly along the screw rod 14. The movement of the moving block 15 drives the long rod 16 to displace synchronously. The long rod 16 drives the mounting frame 18 to swing at multiple angles relative to the connecting plate 11 through the connecting rod 17, thereby realizing fine adjustment of the angle of the drill bit 8 to accurately fit the arc of the patient's bone and the drilling angle requirements.

[0038] Finally, after the angle adjustment is in place, the transmission motor 20 is started to drive the lead screw 21 to rotate, and then drive the positioning block 22 to move linearly along the inner wall of the mounting frame 18, finally realizing the accurate position movement of the drill bit 8 in another dimension perpendicular to the angle adjustment plane, and accurately positioning the drill bit 8 at the target drilling point on the bone. When fine angle adjustment of the drill bit 8 is required, the medical staff can manually rotate the adjusting cap 30, the rotating shaft 25 drives the turntable 26 to rotate, and the steel ball 29 cooperates with the limiting holes 31 on the fixed disk 24 under the action of the elastic sheet 27 to realize adjustment to a tiny angle, ensuring high precision and high adaptability during the drilling process and providing strong technical support for the successful implementation of orthopedic surgery.

Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present utility model.
