Description

Technical Field

[0001] The present invention relates to the technical field of dental handpieces, and particularly to a multi-angle adjustable high-speed dental handpiece. Background Art

[0002] A high-speed dental turbine handpiece is a high-speed rotating cutting medical device driven by air flow, with a rotational speed ranging from 200,000 revolutions per minute to 600,000 revolutions per minute. It is mainly used for cutting tooth bodies, preparing tooth cavities, preparing tooth shapes, and trimming tooth shapes, etc.

[0003] However, most of the existing high-speed dental handpieces have the problem of limited angle adjustment. Traditional high-speed dental handpieces usually adopt a fixed-angle design or can only be adjusted at a limited angle, which makes it difficult for doctors to flexibly adjust the orientation and angle of the high-speed handpiece according to the specific position and shape of the teeth during operation, bringing many inconveniences to the treatment. For example, when dealing with special parts such as the adjacent surfaces and tooth roots of teeth, due to angle limitations, doctors may need to adjust the patient's body position or their own operating posture multiple times, which not only increases the operation difficulty and time, but also may affect the treatment effect and the patient's comfort.

DETAILED DESCRIPTION OF THE INVENTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 7 , the present invention provides a technical solution: a dental high-speed handpiece with multi-angle adjustment, including an upper housing sleeve 1 and a lower housing sleeve 2. One end of the upper housing sleeve 1 is fixedly installed with a grinding shell 3. A turbine grinding assembly is installed inside the grinding shell 3. Six connecting pipes 23 are fixedly installed inside the upper housing sleeve 1. One end of the upper housing sleeve 1 far from the grinding shell 3 is fixedly installed with an inner rotating seat 24. An adjusting gear two 25 is fixedly installed on the outer side of the inner rotating seat 24. A rotating sleeve 5 is fixedly installed on the outer side of the upper housing sleeve 1 far from the grinding shell 3. A rotating magnetic ring 13 is fixedly installed at the bottom of the rotating sleeve 5. A fixed sleeve 4 is fixedly installed on the outer side of one end of the lower housing sleeve 2. An annular rotating groove 32 is opened at the top of the fixed sleeve 4. The upper housing sleeve 1 is rotatably installed on the top of the lower housing sleeve 2. The rotating sleeve 5 is rotatably installed on the top of the fixed sleeve 4. The rotating magnetic ring 13 is rotatably installed inside the annular rotating groove 32. An electromagnet 33 is fixedly installed inside the annular rotating groove 32. A protective shell 7 is fixedly installed on the outer side of the fixed sleeve 4. Two adjusting wheels 8 are rotatably installed inside the protective shell 7. An adjusting gear one 9 is fixedly installed between the adjusting wheels 8. The adjusting gear one 9 and the adjusting gear two 25 are in the same horizontal plane. The outer sides of the adjusting gear one 9 and the adjusting gear two 25 are meshed with each other. A button 10 is installed on the outer side of the fixed sleeve 4. One end of the lower housing sleeve 2 far from the fixed sleeve 4 is fixedly installed with an outer sleeve ring 19. An inner rotating ring 21 is rotatably installed inside the outer sleeve ring 19. A wiring head 20 is fixedly installed inside the inner rotating ring 21.

[0024] Working principle of the above technical solution: First, externally connect a matching dental chair through the terminal 20, and then place the grinding shell 3 inside the patient's oral cavity. The turbine grinding assembly is used to trim the patient's teeth. When it is necessary to change the orientation of the turbine grinding assembly, it is divided into coarse adjustment and fine adjustment. First, the rotating sleeve 5 can be rotated to make the rotating magnetic ring 13 rotate inside the annular rotating groove 32, and make the upper housing sleeve 1 rotate at the end of the lower housing sleeve 2, thereby driving the grinding shell 3 to rotate, so as to coarsely adjust the orientation of the turbine grinding assembly. Then, the medical staff manually pushes the adjusting wheel 8 to rotate, thereby driving the first adjusting gear 9 to rotate, thereby driving the second adjusting gear 25 to rotate, and then driving the upper housing sleeve 1 to rotate through the inner rotating seat 24. Since the tooth number ratio between the first adjusting gear 9 and the second adjusting gear 25 is 1:8, when the first adjusting gear 9 rotates one circle, the second adjusting gear 25 rotates one-eighth of a circle, thereby driving the upper housing sleeve 1 to rotate slowly, prompting the grinding shell 3 to drive the turbine grinding assembly to rotate slowly, so as to finely adjust the orientation of the turbine grinding assembly and improve the adjustment accuracy. In addition, after the adjustment is completed, the button 10 can be pressed to energize the electromagnet 33 to generate magnetic force, thereby adsorbing and fixing the rotating magnetic ring 13, so as to prevent the upper housing sleeve 1 from rotating during use and ensure the normal use of the device.

[0025] In another embodiment, such as Figures 1 - 7As shown, the turbine grinding assembly includes a master turbine block 27 and a slave turbine block 31. One side of the master turbine block 27 is clamped with one side of the slave turbine block 31. A rotating column 26 is rotatably installed at the top of the master turbine block 27. One end of the rotating column 26 away from the master turbine block 27 is fixedly installed with an assembly clamping plate 22. The assembly clamping plate 22 is clamped and installed on one side of the grinding shell 3. One side of the slave turbine block 31 away from the master turbine block 27 is fixedly installed with an assembly seat 30. A grinding head 14 is clamped and installed inside the assembly seat 30. A clamping groove 28 is opened inside one end of the master turbine block 27 away from the rotating column 26. One side of the top of the slave turbine block 31 away from the assembly seat 30 is fixedly installed with a clamping column 29. The specification size of the outer contour of the clamping column 29 matches the specification size of the inner contour of the clamping groove 28. And one end of the clamping column 29 away from the slave turbine block 31 is clamped and installed inside the clamping groove 28. An installation shell one 11 is fixedly installed on the outer side of the grinding shell 3. An endoscope 12 is fixedly installed inside the installation shell one 11. An installation shell two 15 is fixedly installed on the outer side of the grinding shell 3. An LED lamp 16 is fixedly installed inside the installation shell two 15. An atomizing nozzle 18 is fixedly installed on one side of the grinding shell 3. Two filter membranes 17 are fixedly installed on the side of the grinding shell 3 where the atomizing nozzle 18 is installed. One end of a connecting pipe 23 is fixedly connected to a wiring head 20. One end of two of the connecting pipes 23 away from the wiring head 20 is communicated with the grinding shell 3. A connecting wire is sleeved inside two of the connecting pipes 23. And the connecting wires are respectively connected to the endoscope 12 and the LED lamp 16. One of the connecting pipes 23 is communicated with the atomizing nozzle 18. One of the connecting pipes 23 is communicated with the two filter membranes 17.

[0026] After being connected to a matching dental chair through the wiring head 20, gas can be output through one of the connecting pipes 23 to blow the master turbine block 27, so that the master turbine block 27 rotates. Thus, the slave turbine block 31 is driven to rotate through the clamping column 29. Thus, the grinding head 14 is driven to rotate at a high speed through the assembly seat 30 to grind and repair the patient's tooth body. In addition, the gas inside the grinding shell 3 will be discharged through another connecting pipe 23. In addition, cleaning water can be conveyed through one of the connecting pipes 23 and then atomized and sprayed out through the atomizing nozzle 18 to wash during the grinding of the patient's tooth by the grinding head 14. In addition, through one of the connecting pipes 23, the airflow inside the oral cavity can be extracted through the two filter membranes 17 during the grinding of the patient's tooth by the grinding head 14. In addition, the endoscope 12 can be used to photograph the inside of the oral cavity, which is convenient for medical staff to timely understand the situation inside the patient's oral cavity and confirm the area that needs to be repaired on the patient's tooth, confirm the repair amount, and facilitate the subsequent grinding of the patient's tooth by the grinding head 14. The LED lamp 16 can be used to illuminate the inside of the oral cavity.

[0027] In another embodiment, as Figures 1 - 7As shown, a hand-rotating sleeve 6 is fixedly installed on the outer side of the rotating sleeve 5. The hand-rotating sleeve 6 is made of soft rubber, and a notch is provided on the outer side of the hand-rotating sleeve 6.

[0028] The hand-rotating sleeve 6 is provided to facilitate the rotation of the rotating sleeve 5.

[0029] Working principle: First, externally connect the matching dental chair through the wiring head 20, and then place the grinding shell 3 inside the patient's oral cavity. The patient's teeth are trimmed by the turbine grinding assembly. When it is necessary to change the orientation of the turbine grinding assembly, it is divided into coarse adjustment and fine adjustment. First, the rotating sleeve 5 can be rotated to make the rotating magnetic ring 13 rotate inside the annular rotating groove 32, and make the upper shell sleeve 1 rotate at the end of the lower shell sleeve 2, thereby driving the grinding shell 3 to rotate, so as to coarsely adjust the orientation of the turbine grinding assembly. Then, the medical staff manually pushes the adjusting runner 8 to rotate, thereby driving the first adjusting gear 9 to rotate, thereby driving the second adjusting gear 25 to rotate, and then driving the upper shell sleeve 1 to rotate through the inner rotating seat 24. Because the tooth number ratio between the first adjusting gear 9 and the second adjusting gear 25 is 1:8, when the first adjusting gear 9 rotates one circle, the second adjusting gear 25 rotates one-eighth of a circle, thereby driving the upper shell sleeve 1 to rotate slowly, prompting the grinding shell 3 to drive the turbine grinding assembly to rotate slowly, so as to finely adjust the orientation of the turbine grinding assembly and improve the adjustment accuracy. In addition, after the adjustment is completed, the button 10 can be pressed to energize the electromagnet 33 to generate magnetic force, thereby adsorbing and fixing the rotating magnetic ring 13, so as to prevent the upper shell sleeve 1 from rotating during use and ensure the normal use of the device. After being connected to the matching dental chair through the wiring head 20, gas can be output through one of the communicating pipes 23 to blow the main and slave turbine blocks 27, so that the main and slave turbine blocks 27 rotate, and then drive the driven turbine block 31 to rotate through the clamping column 29, and then drive the grinding head 14 to rotate at a high speed through the assembly seat 30 to grind and repair the patient's tooth body. In addition, the gas inside the grinding shell 3 will be discharged through another communicating pipe 23. In addition, cleaning water can be conveyed through one of the communicating pipes 23 and then atomized and sprayed out through the atomizing nozzle 18 to wash during the grinding of the patient's teeth by the grinding head 14. In addition, through one of the communicating pipes 23, the air flow inside the oral cavity can be extracted through the two filter membranes 17 during the grinding of the patient's teeth by the grinding head 14. In addition, the endoscope 12 is provided to photograph the inside of the oral cavity, which is convenient for the medical staff to timely understand the situation inside the patient's oral cavity and confirm the area that needs to be trimmed of the patient's teeth, and confirm the repair volume, which is convenient for subsequent grinding of the patient's teeth by the grinding head 14. The LED lamp 16 is provided to illuminate the inside of the oral cavity. The hand-rotating sleeve 6 is provided to facilitate the rotation of the rotating sleeve 5.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
