This design allows the connecting member to rotate with the drive shaft due to the toothed connection between the connecting member and one end of the drive shaft. The upper drive shaft is detachably connected to the inner cutter tube, allowing the upper drive shaft to simultaneously drive the inner cutter tube's axial movement and rotate around its circumference. Furthermore, the other end of the upper drive shaft is connected to a spring within the connecting member, ensuring that the contours of the upper and lower drive shafts are always aligned and pressed together. A groove in the inner cutter tube allows for the insertion of a pin, securing the connection between the inner cutter tube and the upper drive shaft. The groove and pin design facilitates both installation and removal of the inner cutter tube and the upper drive shaft. A steel ball hole in the lower drive shaft allows for smooth installation of the upper steel ball. The location of the steel ball hole aligns with that of the upper drive shaft, preventing direct contact between the upper and lower drive shaft contours, thus preventing frictional damage caused by direct contact between the upper and lower drive shaft contours when the upper drive shaft rotates. The magnetic induction component mounted on the upper transmission shaft can sense the rotation speed of the upper transmission shaft.

Then, the air pump can be started by controlling the switch assembly, thereby having an absorption effect on the air suction holes. Of course, a flap is installed in the suction hole, and the flap is detachably connected to the file head, that is, the flap naturally rotates toward the cavity under the absorption effect, thereby opening the suction hole. In this way, the bone chips ground off in the human body (the grinding and filing work place) can be smoothly introduced into the cavity through the suction hole. However, when the air pump stops suctioning, the flap can automatically flip toward the outside of the cavity, closing the suction hole, thereby preventing objects in the cavity from being introduced into the body through the suction hole.

[0013] Preferably, the flaps include a plurality of flaps, which are symmetrically distributed around the center of the air intake hole, and the length of the two flaps is equal to the diameter of the air intake hole. This design, by symmetrically distributing the flaps around the center of the air intake hole, allows the flaps to be flipped, and the corresponding flaps can be opened or closed smoothly. The length of the two flaps is equal to the diameter of the air intake hole, which is a structural design that smoothly closes the air intake hole, thus facilitating the passage and resistance of bone chips.

The outer ring is connected to the file head via a micro-spring. Under the suction of the air pump, the flap flips into the cavity. After absorbing the bone chips, the flap automatically flips out of the cavity under the elastic effect of the micro-spring to smoothly close the suction hole, thus preventing the bone chips from returning to the body. By installing a retaining ring on the file head, with one end of the flap groove placed on the outer edge of the suction hole and the other end placed inside the suction hole, and the retaining ring placed on the flap groove at the outer edge of the suction hole, the flap can be blocked by the retaining ring when it flips out of the cavity, preventing the flap from flipping too far and affecting the work of blocking bone chips. The diameter of the flap groove is larger than the diameter of the retaining ring, which is a structural design that allows the retaining ring to smoothly block the flap.

A steel ball 18 is installed in the steel ball hole. The steel ball 18 is connected to the lower transmission shaft 16. A magnetic induction component is set on the upper transmission shaft 17. A plurality of magnets 14 are installed in the magnetic induction component. The magnet 14 is placed in the shell 13. The plurality of magnets 14 are distributed with the center of the upper transmission shaft 17 as the reference. The file head 4 is connected to the inner knife tube 21.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the inner blade tube 21 is provided with a cavity 7, in which an air pump is installed. The air pump is electrically connected to the switch assembly 5. The file head 4 is symmetrically provided with a plurality of air intake holes 8, which are connected to the cavity 7 and are positioned between adjacent file blocks 6. A flap 11 is installed in the air intake hole 8 and is detachably connected to the file head 4. The flaps 11 are symmetrically distributed around the center of the air intake hole 8, and the length of two flaps 11 is equal to the diameter of the air intake hole 8. The file head 4 is provided with a number of flap grooves 9, the flap grooves 9 are placed in the suction hole 8, the flap 11 matches the flap groove 9, a rolling bearing 10 is installed on the flap groove 9, the rolling bearing 10 includes an inner ring and an outer ring, the inner ring is installed with a connecting shaft, the rolling bearing 10 is connected to the file head 4 through the connecting shaft, the flap 11 is connected to the outer ring, a micro spring is installed on the outer ring, the micro spring is connected to the file head 4, a number of retaining rings 12 are installed on the file head 4, one end of the flap groove 9 is placed on the outer edge of the suction hole 8, the other end of the flap groove 9 is placed in the suction hole 8, the retaining ring 12 is placed on the flap groove 9 at the outer edge of the suction hole 8, and the diameter of the flap groove 9 is larger than the diameter of the retaining ring 12.

[0028] First, the upper transmission shaft 17 and the lower transmission shaft 16 are inserted into the housing 13, and the housing 13 and the lower transmission shaft 16 are connected using a snap-fit ​​connection. The connection is simple and easy. A steel ball 18 is installed in the steel ball hole at the end of the lower transmission shaft 16. The upper transmission shaft 17 and the lower transmission shaft 16 are placed in a straight line, and the location of the steel ball hole corresponds to the location of the upper transmission shaft 17. This prevents the contour surface of the upper transmission shaft 17 and the contour surface of the lower transmission shaft 16 from directly contacting each other, preventing the contour surface of the upper transmission shaft 17 and the contour surface of the lower transmission shaft 16 from directly squeezing each other when the upper transmission shaft 17 rotates, causing damage due to friction. A magnetic induction element is installed on the upper transmission shaft 17. The magnetic induction element is equipped with a plurality of magnets 14. The magnets 14 are distributed around the center of the upper transmission shaft 17. This allows the magnetic field effect to be sensed from all angles of the magnetic induction element, and the speed is automatically adjusted by identifying the position and number of magnets 14.

[0029] Then, the connecting piece 1 is put on the outer surface of the upper transmission shaft 17, so that the connecting piece 1 and one end of the upper transmission shaft 17 are connected with a tooth shape, and a spring 15 is installed in the connecting piece 1. The other end of the upper transmission shaft 17 is connected to the spring 15. A waist groove 20 is provided on the prepared inner knife tube 21, so it can be inserted into the waist groove 20 through the control of the pin 19. In this way, the inner knife tube 21 and the upper transmission shaft 17, which are easy to disassemble and install, are stably connected. A file head 4 is installed on the other end of the inner knife tube 21, and a cavity 7 is provided on the inner knife tube 21. Not only that, the outer knife tube 3 put on the outer surface of the inner knife tube 21 can also be well connected with the lower transmission shaft 16. Then, under such a structural design, the upper transmission shaft 17 can rotate on the outer periphery of the inner knife tube 21 under the drive of the connecting piece 1. Due to the contour The surface has a special up and down undulating curved surface. When the contour surface of the upper transmission shaft 17 fits and squeezes with the contour surface of the lower transmission shaft 16, because the lower transmission shaft 16 is fixed and cannot move, the upper transmission shaft 17 performs left and right axial reciprocating motion relative to the lower transmission shaft 16. The upper transmission shaft 17 is axially fixed to the inner knife tube 21, so the upper transmission shaft 17 drives the inner knife tube 21 to reciprocate relative to the lower transmission shaft 16. Not only that, the lower transmission shaft 16 and the outer knife tube 3 are also connected by a pin 19, so the inner knife tube 21 is reciprocating relative to the outer knife tube 3, that is, the file head 4 is driven to reciprocate, so that the connecting part 1 is well connected to the planing handle, and the file head 4 can be made to perform axial reciprocating motion by controlling the rotation of the connecting part 1 to start grinding the patient's bone tissue surface.

[0030] In the process of controlling the connection member 1 to drive the movement of the outer blade tube 3, the end of the outer blade tube 3, that is, the file block 6, may be placed in a dark environment. Moreover, some organs in the human body cannot be touched, and of course bones cannot be cut. For example, there are many small bones connected under the ribs. In the state where it is not convenient to cut the ribs, the operation can only be carried out smoothly in a bright environment. A warning installation shaft 22 is installed on the file head at the top of the outer knife tube 3, and a number of file blocks 6 are distributed in a ring shape with the file head as the center, that is, a number of file blocks 6 are distributed in a ring shape with the warning installation shaft 22 as the center, and a distance sensor 1, a distance sensor 2, a camera 1 and a camera 2 are installed on the warning installation shaft 22. Here, the distance sensor 1 and the camera 1 are both placed at the top position of the warning installation shaft 22, and the number of distance sensors 2 and the number of cameras 2 are distributed in a ring shape with the warning installation shaft 22 as the center, so the distance sensor 1 can always sense the distance between the top of the warning installation shaft 22 and the organ, and the camera 1 can always shoot the organ condition in front of the top of the warning installation shaft 22. The first and second cameras are constantly sensing the distance between the organs and the warning installation shaft 22. The second camera constantly captures the state of the organs around the warning installation shaft 22 and transmits the information to the single-chip microcomputer 23. After the single-chip microcomputer 23 processes the information, the processed information is transmitted to the display 24 and the alarm bell. Then, the specific situation around the warning installation shaft 22 can be clearly understood through the display 24. If the distance between the warning installation shaft 22, that is, the file block 6, and the organ is less than the distance information stored in the single-chip microcomputer 23, the alarm bell will immediately sound an alarm to remind the person to pay close attention. In this way, the purpose of installing a component that can open the attention of the surrounding environment and provide prompt information in a timely manner is achieved. Here, the first and second cameras have a lighting effect, or are directly installed with a small light, so that the first and second cameras can capture the organs in a bright state, and this captured information can be selected to be dynamic.

[0031] During the grinding process of the bone tissue surface, the ground bone chips may remain in the patient's body, which may have an adverse effect on the grinding work and may even affect the patient's health. In this case, it is necessary to manually control the switch component 5 installed on the transmission structure 2 to start the air pump electrically connected to the switch component 5. A plug can be installed on the connector 1. By making the electrical connection between the plug and the external power supply, the air pump can work smoothly using the power brought by the plug. A number of file blocks 6 are evenly installed on the file head 4. The file blocks 6 are symmetrically distributed on the outer surface of the file head 4. Then when the file head 4 rotates, the surface of the bone tissue can be in contact with the file block 6 at all times and be ground under the friction of the file block 6. Suction holes 8 are provided between adjacent file blocks 6. The suction effect of the air pump can allow the ground bone chips to be introduced into the cavity 7 on the inner knife tube 21 through the suction holes 8. The air pump here uses a micro air pump, and several of them can also be installed. The installation position of the air pump can correspond to the installation position of the file block 6 inside and outside. This not only strengthens the installation stability of the file block 6, but also ensures that the bone chips outside each suction hole 8 can be smoothly sucked into the cavity 7, which is convenient for the discharge of bone chips.

[0032] A flap groove 9 is provided at the suction hole 8, one end of the flap groove 9 is placed on the outer edge of the suction hole 8, and the other end is placed inside the suction hole 8, and a retaining ring 12 is installed on the flap groove 9 at the outer edge of the suction hole 8, the diameter of the flap groove 9 is larger than the diameter of the retaining ring 12, and a rolling bearing 10 is also installed on the flap groove 9, the inner ring of the rolling bearing 10 is connected to the file head 4 through the connecting shaft, and the outer ring of the rolling bearing 10 is installed with a flap 11, and the flap 11 can be connected to the file head 4 through a micro spring, so that when the air pump is working, under the attraction of the air pump, the flap 11 is flipped toward the direction of the cavity 7, and the bone chips outside the suction hole 8 can be smoothly introduced into the cavity 7 through the suction hole 8 to avoid continuing to remain in the patient's body. When the air pump is not needed or stops working unexpectedly, the flap 11 can automatically flip toward the outside of the cavity 7 under the elastic effect of the micro-spring until it touches the retaining ring 12. The suction hole 8 can be smoothly closed by the retaining ring 12 to prevent the objects in the cavity 7, especially the bone chips in the cavity 7, from being discharged back into the patient's body. Here, a plurality of flaps 11 are installed on a suction hole 8, and the plurality of flaps 11 are symmetrically distributed with the center of the suction hole 8 as the center. One end of the flap 11 is connected to the outer ring of the rolling bearing 10, and the other end can be provided with a mortise and tenon, so that when the two flaps 11 corresponding to the position flip toward each other, they can be smoothly combined through the mortise and tenon, so that the suction hole 8 can be smoothly closed to prevent the objects in the cavity 7 from being discharged.

[0033] The file thus manufactured can be used for grinding the surface of the patient's bone tissue. Under the control of the connecting member 1 and the control of the switch assembly 5 on the transmission structure 2, the grinding work on the surface of the patient's bone tissue can be carried out stably. The manufacturing of the file is thus successfully completed.
