Description

Technical Field

[0001] The utility model relates to the technical field of dental drill equipment, specifically a dental drill equipment for verifying cutting equipment. Background Technique

[0002] A dental drill is a professional tool used in the field of oral medicine, mainly used for drilling, repairing and treating teeth, and also for drilling holes when implanting implants. A dental drill is a medical device specifically used for dental surgery. In dental implant surgery, the main function of the dental drill is to prepare the implant bed, that is, to drill holes in the jawbone suitable for implanting implants. The shape and size of the drill bit of the dental drill will be selected according to different surgical needs and implant positions to ensure the accuracy and safety of the surgery.

[0003] Verifying the cutting force of the dental drill is crucial for ensuring the success of the surgery and the safety of the patient. The cutting force refers to the force exerted by the dental drill on the jawbone tissue during the drilling process. If the cutting force is too large, it may cause excessive damage to the jawbone tissue and increase the surgical risk; if the cutting force is too small, the drilling operation may not be effectively completed, affecting the implant effect of the implant. Therefore, verifying the cutting force of the dental drill can ensure that the dental drill has an appropriate cutting force during use, which can not only meet the surgical needs but also cause unnecessary damage to the jawbone tissue. This helps to improve the success rate of the surgery, reduce the surgical risk, and at the same time ensure the comfort and satisfaction of the patient.

[0004] For the cutting force test of the dental drill, it is necessary to test the cutting force on the top and side of the dental drill respectively. The dental drill needs to cut a fixed depth on the bone block with a fixed load and a fixed rotational speed, and at the same time measure the cutting time. The shorter the time, the stronger the cutting force; the longer the time, the weaker the cutting force.

[0005] The patent with the patent application number CN202111173609.5 discloses a dental drill cutting tester, belonging to the field of dental drill cutting testers. A dental drill cutting tester includes a base, a clamping frame and a mounting frame. A screw rod is arranged on the top of the base, and a sliding seat penetrates through the screw rod. A bracket is arranged on the top of the sliding seat. A rack is arranged on the outer side of the bracket. A lifting frame is installed around the bracket. A first rotating shaft is arranged inside the lifting frame, and a gear is arranged on the outer side of the first rotating shaft. A fixed rod is arranged on the outer side of the lifting frame, and a second rotating shaft is connected to the side of the fixed rod. The clamping frame is installed on the outer side of the second rotating shaft. A connecting shaft is arranged on the outer side of the clamping frame, and a connecting rod is arranged on the outer side of the connecting shaft. The present invention is provided with a clamping frame, which can conveniently install different test samples to detect the cutting effect of the dental drill on different materials, and the equipment can flexibly adjust different test positions for side viewing, facilitating the equipment to collect different data for testing.

[0006] The following defects exist in the prior art: only the cutting force at the top of the drill bit can be tested, and the verification of the side cutting force is lacking; the clamping of the bone block is not flexible, and it is necessary to drill holes at multiple positions on a thick bone block and also test the side cutting at the edge of a thin bone block.

[0073] Embodiment 2:

[0074] This embodiment provides a specific implementation for verifying the dental drill device of a cutting device during side cutting tests.

[0075] Workbench 1;

[0076] Lifting table 3, slidably mounted on the workbench 1 up and down through guide rails;

[0077] Dental drill 4, rotatably connected below the lifting table 3. A detachable cylindrical drill bit 41 is provided at the lower end of the dental drill 4. The other end of the dental drill 4 is connected to a motor driven at a preset speed through a hose 42. The motor is a speed-regulating motor;

[0078] Fixture 6, a fixture 6 for clamping the bone block 7 is provided in the fixture chute 5 on the workbench 1;

[0079] One side of the lifting table 3 is connected to a motor driven at a preset load. A rotating seat 31 is provided at the bottom of the other side of the lifting table 3. The rotating seat 31 is rotatably connected to the rotating block 32. The rotating angle of the rotating block 32 is 90 degrees. The drill bit 41 maintains a horizontal angle and cuts downward. A fixing seat 34 for fixing the dental drill 4 is slidably connected to the rotating block 32 through a slide bar 33;

[0080] A first lead screw 51 is provided in the fixture chute 5. The first lead screw 51 is threadedly connected to the fixture base 61 at the bottom of the fixture 6. Rotating the first lead screw 51 drives the fixture 6 to move. The fixture base 61 fits against the inner wall of the fixture chute 5, so that rotating the first lead screw 51 drives the fixture base 61 to move.

[0081] Specifically, the cylindrical drill bit 41 is a cemented carbide dental drill rotating at a speed of 6000 r / min; the bone block 7 is a polymethyl methacrylate plate with a thickness of 1 mm; the downward load of the drill bit 41 is 0.3 kgf; the downward cutting distance of the drill bit 41 is 5D (tool diameter).

[0082] Working principle: When testing the top cutting of the drill bit 41, as Figure 5 shown, use the fixture 6 to clamp the bone block 7, clamp the thick bone block 7 by adjusting the knob 661 and the screw 641, and adjust the position of the bone block 7 in the front-back direction. Then, adjust the position of the bone block 7 in the left-right direction by rotating the turning handle 52, so as to control the drill bit 41 to align with any point on the bone block 7 for drilling. At this time, the rotating angle of the rotating block 32 is 0 degrees, and the drill bit 41 maintains a vertical angle and cuts downward. Control the motor connected to the lifting table 3 through the control panel 2, so that the lifting table 3 presses down a fixed distance with a fixed load. At the same time, control the motor connected to the dental drill 4 through the control panel 2, so that the dental drill 4 cuts at a fixed speed. After the drill bit 41 completes the fixed cutting distance, the control panel 2 records the time taken; when it is necessary to test the side cutting of the drill bit 41, as Figures 6-7As shown, the rotating block 32 rotates by 90 degrees, the drill bit 41 maintains a horizontal angle and cuts downward, and the fixing seat 34 is fitted on the rotating block 32 by adjusting the bolt on the sliding rod 33, so as to reduce the offset distance when the drill bit 41 is placed sideways. Then, rotate the handle 52 to align the side of the drill bit 41 with the edge of the thin bone block 7. Then, control the motor connecting the lifting table 3 through the control panel 2 to make the lifting table 3 press down a fixed distance with a fixed load. At the same time, control the motor connecting the dental drill 4 through the control panel 2 to make the dental drill 4 cut at a fixed speed. After the drill bit 41 completes the fixed cutting distance, the control panel 2 records the time taken to complete, so as to complete the test of the top and side cutting of the same drill bit 41. It is also possible to replace the drill bit 41 at the end of the dental drill 4 for repeated testing.

[0083] In summary, for the dental drill device of this verification cutting device, a rotatably connected rotating block 32 is arranged below the lifting table 3, a slidably connected fixing seat 34 is arranged on the rotating block 32, and finally the dental drill 4 is fixedly connected to the fixing seat 34. The dental drill 4 is connected to the motor through a hose 42, so that the dental drill 4 can cut downward at two angles, vertical and horizontal, thereby enabling the testing of the cutting forces on the top and side of the drill bit 41.

[0084] For the dental drill device of this verification cutting device, a fixture 6 driven to move by a first lead screw 51 is arranged in the fixture chute 5, a second clamping seat 63 driven to move by a second lead screw 66 is arranged on the fixture 6, a second clamping block 65 is fixedly connected to the second clamping seat 63, and a first clamping block 64 controlled in position by a screw 641 is arranged on the first clamping seat 62. Thus, the positions of both the second clamping block 65 and the first clamping block 64 can be adjusted, so as to flexibly control the position where the bone block 7 is clamped, enabling the drill bit 41 to cut at any position on the thick bone block 7 or at the edge of the thin bone block 7.

[0085] For the dental drill device of this verification cutting device, by providing a detachable drill bit 41, the cutting forces of drill bits of different specifications can be measured.

[0086] For the dental drill device of this verification cutting device, a hose 42 is arranged on the dental drill 4 to connect the motor, and the motor is arranged in the lifting table 3 that moves up and down synchronously with the dental drill 4, avoiding the problem of the hose 42 being pulled.

[0087] For the dental drill device of this verification cutting device, by providing a motor that can adjust the descending load and descending distance to connect the lifting table 3, and then providing a motor that can adjust the rotation speed to connect the dental drill 4, the drill bit 41 can cut downward a fixed distance at a fixed speed and load. Then, detect and record the cutting time through the control panel 2 to verify the cutting ability of the drill bit 41.
