TECHNICAL FIELD

[0001] The present application relates to the technical field of dental medical devices, in particular to a dental restoration clinical oral foreign body adsorption device. BACKGROUND

[0002] Oral dentistry covers the maintenance of tooth and oral tissue health, disease treatment and aesthetic improvement, and the core includes caries repair, periodontal treatment, orthodontic correction, dental implantation and aesthetic repair, etc. The oral dental restoration technology is mainly used for repairing tooth defects, decay or abnormal shape, and common methods include filling, inlay, full crown, veneer, etc. The tooth damage degree, position and patient demand need to be selected.

[0003] During dental restoration, the patient has a tooth cavity and a large amount of calculus and dirt on the tooth, and the tooth surface needs to be cleaned. During the cleaning process and the restoration process, tooth debris or dental plaque and other foreign matter will fall off and remain in the patient's oral cavity, which will affect the patient's comfort and the work progress. The common adsorption device needs to be operated by medical staff to perform adsorption work, and the adsorption work will collide with the cleaning adsorption device, which will hinder the operation, increase the operation difficulty, and make it difficult to adsorb foreign matter. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a dental restoration clinical oral foreign body adsorption device to solve the problem that the common adsorption device needs to be operated by medical staff to perform adsorption work, and the adsorption work will collide with the cleaning adsorption device, which will hinder the operation, increase the operation difficulty, and make it difficult to adsorb foreign matter.

[0005] To achieve the above purpose, the present application is realized by the following technical scheme: a dental restoration clinical oral foreign body adsorption device, comprising a hollow adsorption rod body, an adsorption head is installed at the bottom of the adsorption rod body, a filter mechanism is arranged on the side surface of the adsorption rod body, the filter mechanism comprises a filter box in communication with the adsorption rod body, an adsorption device is installed on the side surface of the filter box, and a ventilation hole is formed at the position opposite to the adsorption device in the filter box; A cleaning mechanism is arranged in the interior of the adsorption rod body, the cleaning mechanism comprises two connecting rods slidingly arranged in the adsorption rod body, a cleaning brush and a cleaning needle are respectively installed at the bottom ends of the two connecting rods, the top ends of the two connecting rods are slidingly extended to the outside of the adsorption rod body, and a driving mechanism for driving the two connecting rods to vibrate for cleaning work is arranged at the top end of the adsorption rod body.

[0006] By adopting the above technical solution, an adsorption rod, adsorption head, filter box, adsorber, filter plate, and holder are set up. The filter box works in conjunction with the adsorber, and the adsorber is turned on by control. Foreign objects inside the oral cavity can pass through the adsorption rod into the filter box to achieve adsorption and treatment of foreign objects inside the oral cavity. By setting up a cleaning brush and a cleaning needle, the cleaning brush is used to quickly clean the tooth surface, and the cleaning needle can perform detailed cleaning of the interdental areas to meet different cleaning needs. The two are used together, eliminating the need for medical staff to repeatedly change and handle instruments or hold multiple instruments during operation, thus improving the convenience of operation.

[0007] Preferably, the driving mechanism includes a mounting sleeve fixed to the top of the adsorption rod, a vibrator mounted above the mounting sleeve, a guide plate rotatably mounted on the output end of the vibrator, and two connecting rods slidably mounted in an annular slide rail on the guide plate. Two ball bearings are fixed to the outer surface of the connecting rods, and the two ball bearings respectively fit against the upper and lower surfaces of the guide plate.

[0008] Preferably, the guide disc is inclinedly disposed within the mounting sleeve, a limit frame is rotatably mounted on the mounting sleeve, and the guide disc is slidably disposed on the outer surface of the limit frame.

[0009] Preferably, a plurality of guide rods are fixedly installed on the limiting frame, a plurality of insertion holes for inserting the guide rods are provided on the mounting sleeve, and an elastic element is fixed on the limiting frame, with the other end of the elastic element fixed to the surface of the mounting sleeve.

[0010] Preferably, the filter box has a filter plate inside, and a bracket is installed at the bottom of the filter plate. The bracket is snapped onto the filter box and has a round hole in the bracket facing the vent. A partition is slidably installed inside the filter box at the vent.

[0011] Preferably, a magnetic block one is fixed on the side of the partition and the card holder near the adsorber, and a magnetic block two, which works in conjunction with the magnetic block one, is installed on the inner wall of the filter box below the vent.

[0012] Preferably, the adsorption head is rotatably mounted on the adsorption rod body via an electric rotating shaft, and the adsorption head and the adsorption rod body are connected by an elastic tube.

[0013] Preferably, an electric push rod is fixed to the side of the adsorption rod, and an oral cavity support is fixed to the side of the electric push rod. The oral cavity support consists of a horizontal plate and two rollers rotatably mounted on the horizontal plate.

[0014] Preferably, a protective sleeve is fitted on the outer surface of the two connecting rods, the protective sleeve is fixedly installed on the outer surface of the two connecting rods, and a plurality of crushing blades are installed obliquely on the outer surface of the protective sleeve.

[0015] Preferably, a camera and a light are fixed on the adsorption head near the cleaning brush and cleaning needle, and a display screen for use with the camera is fixed on the mounting sleeve.

[0016] Working principle: Place the suction rod and suction head in the patient's mouth, control the start, and the electric push rod drives the oral cavity support to move. The position of the oral cavity support can be adjusted. The oral cavity support can stretch and lift the patient's mouth. Then control the start of the suction device, which allows foreign objects in the oral cavity to enter the filter box through the suction rod, thus realizing the adsorption and treatment of foreign objects in the oral cavity. When it is necessary to clean foreign objects from teeth, turn on the vibrator. The vibrator drives the guide plate to vibrate. The vibration of the guide plate drives the connecting rod to vibrate through the ball stop. The vibration of the connecting rod can drive the cleaning brush and cleaning needle to vibrate synchronously, thereby achieving the cleaning of teeth. At the same time, the upward movement of the limiting bracket drives the guide rod away from the insertion hole, which can rotate the limiting bracket. The rotation of the limiting bracket drives the guide bracket to rotate and adjust its angle. The limiting bracket is released and, under the action of the elastic element, moves downward to drive the guide rod into the insertion hole, thereby fixing the limiting bracket. The rotating limit bracket drives the guide plate to rotate. Due to the inclined design of the guide plate, the two connecting rods slide inside the annular slide when the guide plate rotates. Simultaneously, under the action of the ball stop, they move up and down with the rotation of the guide plate, switching between the upper and lower positions. This allows for the replacement of the cleaning brush and cleaning needle. Depending on different usage needs, either the cleaning brush or the cleaning needle can be selected for operation. This invention provides a dental foreign body adsorption device for clinical use in dental restoration. It has the following beneficial effects: 1. This invention comprises a vibrator, a limiting frame, a guide plate, connecting rods, a cleaning brush, and a cleaning needle. The vibrator drives the guide plate to vibrate. Dental vibrators are existing technology and will not be elaborated upon here. The vibration of the guide plate, via a ball stop, causes the connecting rods to vibrate accordingly. The vibration of the connecting rods drives the cleaning brush and cleaning needle to vibrate synchronously, thus achieving tooth cleaning. Simultaneously, rotating the limiting frame causes the guide plate to rotate. Due to the inclined design of the guide plate, the two connecting rods slide within the annular track during rotation. Simultaneously, under the action of the ball stop, they move up and down with the rotation of the guide plate, switching between upper and lower positions. This allows for quick replacement of the cleaning brush and cleaning needle according to different usage needs, eliminating the need for additional placement or retrieval of instruments and improving operational convenience. Similarly, multiple other operating instruments can be added for combined use.

[0017] 2. This invention, by setting a guide rod and an elastic element, such as a leaf spring, helical spring, torsion bar spring, or rubber spring (preferably a helical spring), moves the limiting frame upward, causing the guide rod to move away from the insertion hole. This allows the limiting frame to rotate, which in turn rotates the guide frame to adjust its angle, thereby enabling the replacement of the cleaning brush and cleaning needle. Loosening the limiting frame allows it to move downward under the action of the elastic element, driving the guide rod to insert into the insertion hole, thus fixing the limiting frame and preventing shaking or displacement during use.

[0018] 3. This invention, by setting up an adsorption rod, adsorption head, filter box, adsorber, filter plate, and clip, allows foreign objects inside the oral cavity to pass through the adsorption rod and enter the filter box, thus achieving the adsorption and treatment of foreign objects inside the oral cavity. The filter plate and clip are designed to isolate foreign objects, preventing them from entering the adsorber and affecting its normal operation. The clip facilitates the installation and removal of the filter plate, making it easy to clean foreign objects and preventing blockage caused by prolonged use.

[0019] 4. This invention incorporates a protective sleeve and a crushing blade. The protective sleeve protects and isolates the connecting rods, preventing foreign objects from entering and causing jamming. When the two connecting rods vibrate up and down, the crushing blade vibrates synchronously, crushing any foreign objects that enter, further preventing jamming.

[0020] 5. This invention incorporates a camera, a lighting fixture, and a display screen. Both the lighting fixture and the camera are equipped with transparent protective covers. Together with the display screen, they make it easier for medical staff to view the internal condition of the oral cavity and facilitate their operation. Attached Figure Description

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a dental foreign body adsorption device for clinical dental restoration, comprising a hollow adsorption rod 1, an adsorption head 4 installed at the bottom of the adsorption rod 1, a filter mechanism 6 provided on the side of the adsorption rod 1, the filter mechanism 6 including a filter box 601 connected to the adsorption rod 1, an adsorber 602 installed on the side of the filter box 601, and a vent hole opened inside the filter box 601 directly opposite the adsorber 602. A filter plate 604 is provided inside the filter box 601, a bracket 605 is installed at the bottom of the filter plate 604, the bracket 605 is snapped onto the filter box 601, and a round hole is opened on the bracket 605 directly opposite the vent. A partition 603 is slidably provided inside the filter box 601 at the vent position.

[0025] By setting up an adsorption rod 1, an adsorption head 4, a filter box 601, an adsorber 602, a filter plate 604, and a holder 605, the filter box 601 works in conjunction with the adsorber 602 to control the opening of the adsorber 602, allowing foreign objects inside the oral cavity to enter the filter box 601 through the adsorption rod 1, thus achieving the adsorption and treatment of foreign objects inside the oral cavity. The filter plate 604 and the holder 605 are set to isolate foreign objects, preventing them from entering the adsorber 602 and affecting its normal operation. The holder 605 facilitates the installation and removal of the filter plate 604, making it easy to clean foreign objects and preventing blockage caused by prolonged use.

[0026] For details, please refer to the appendix. Figure 8 Magnetic block one is fixed on the side of the partition 603 and the card holder 605 near the adsorber 602. Magnetic block two, which works in conjunction with magnetic block one, is installed on the inner wall of the filter box 601 below the vent.

[0027] By setting up magnetic block one and magnetic block two, when the card holder 605 is inserted into the filter box 601, the card holder 605 will push the partition 603 upward, so that the partition 603 is away from the vent. The card holder 605 will move to the vent and be attracted to magnetic block two, thus fixing the card holder 605. When the card holder 605 is pulled out, the partition 603 returns to its original position under the action of gravity and comes into contact with magnetic block two, thus fixing the partition 603 and thus isolating the vent.

[0028] For details, please refer to the appendix. Figure 2 - Appendix Figure 4 The adsorption rod body 1 is equipped with a cleaning mechanism 3. The cleaning mechanism 3 includes two connecting rods 303 that are slidably disposed inside the adsorption rod body 1. The bottom ends of the two connecting rods 303 are respectively equipped with a cleaning brush 304 and a cleaning needle 305. The top ends of the two connecting rods 303 are slidably extended to the outside of the adsorption rod body 1. The top end of the adsorption rod body 1 is provided with a drive mechanism 2 for driving the two connecting rods 303 to vibrate and perform cleaning work.

[0029] By incorporating a cleaning brush 304 and a cleaning needle 305, the cleaning brush 304 is used for quick cleaning of the tooth surface, while the cleaning needle 305 can perform detailed cleaning of the interdental areas to meet different cleaning needs. Combining the two eliminates the need for medical staff to repeatedly change or handle multiple instruments during the operation, thus improving the convenience of operation.

[0030] For details, please refer to the appendix. Figure 6 and attached Figure 7 The driving mechanism 2 includes a mounting sleeve 201 fixed to the top of the adsorption rod 1. A vibrator 204 is mounted above the mounting sleeve 201. A guide plate 203 is rotatably mounted on the output end of the vibrator 204. Two connecting rods 303 are slidably mounted in an annular slide rail on the guide plate 203. Two ball stops 306 are fixed on the outer surface of the connecting rods 303. The two ball stops 306 are respectively attached to the upper and lower surfaces of the guide plate 203. The guide plate 203 is inclinedly arranged inside the mounting sleeve 201. A limit frame 202 is rotatably mounted on the mounting sleeve 201, and the guide plate 203 is slidably arranged on the outer surface of the limit frame 202.

[0031] By configuring a vibrator 204, a limiting frame 202, a guide plate 203, a connecting rod 303, a cleaning brush 304, and a cleaning needle 305, the vibrator 204 drives the guide plate 203 to vibrate. The dental vibrator 204 is existing technology and will not be elaborated upon here. The vibration of the guide plate 203 drives the connecting rod 303 to vibrate synchronously via a ball stop 306. The vibration of the connecting rod 303 drives the cleaning brush 304 and the cleaning needle 305 to vibrate synchronously, thereby achieving the cleaning of the teeth. Simultaneously, the limiting frame rotates. 202 can drive the guide plate 203 to rotate. Due to the inclined setting of the guide plate 203, when the guide plate 203 rotates, the two connecting rods 303 will slide inside the annular slide. At the same time, under the action of the stop ball 306, they will move up and down with the rotation of the guide plate 203, realizing the switching of the up and down position. The cleaning brush 304 and cleaning needle 305 can be quickly replaced according to different usage needs without the need to place and retrieve other tools, improving the convenience of operation. Similarly, multiple other operating tools can also be added for combined use.

[0032] For details, please refer to the appendix. Figure 6 and attached Figure 7 A number of guide rods 206 are fixedly installed on the limiting frame 202, and a number of insertion holes for the guide rods 206 are opened on the mounting sleeve 201. An elastic element 205 is fixed on the limiting frame 202, and the other end of the elastic element 205 is fixed to the surface of the mounting sleeve 201.

[0033] By setting a guide rod 206 and an elastic element 205, the elastic element 205 can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring. Moving the limiting frame 202 upward causes the guide rod 206 to move away from the insertion hole, which can rotate the limiting frame 202. The rotation of the limiting frame 202 drives the guide frame to rotate and adjust its angle, thereby realizing the replacement of the cleaning brush 304 and the cleaning needle 305. Loosening the limiting frame 202 allows it to move downward under the action of the elastic element 205, driving the guide rod 206 to be inserted into the insertion hole, thereby fixing the limiting frame 202 and preventing the problem of shaking and displacement during use.

[0034] For details, please refer to the appendix. Figure 1 Appendix Figure 5 and attached Figure 9 An electric push rod 7 is fixed to the side of the adsorption rod 1, and an oral cavity bracket 8 is fixed to the side of the electric push rod 7. The oral cavity bracket 8 consists of a horizontal plate and two rollers that are rotatably mounted on the horizontal plate.

[0035] By setting up an electric push rod 7 and an oral support 8, the electric push rod 7 drives the oral support 8 to move, which can adjust the position of the oral support 8. The oral support 8 can support and lift the patient's mouth, making it easier for medical staff to operate without the need for a separate pressure plate, thus further improving the ease of operation.

[0036] For details, please refer to the appendix. Figure 1 Appendix Figure 5 and attached Figure 9 The adsorption head 4 is rotatably mounted on the adsorption rod 1 via an electric rotating shaft 9, and the adsorption head 4 and the adsorption rod 1 are connected by an elastic tube 10.

[0037] By setting up an electric rotating shaft 9 and an elastic tube 10, the electric rotating shaft 9 can be controlled by a self-locking motor. A control button is set on the adsorption rod 1. The electric rotating shaft 9 controls the adsorption head 4 to rotate, which can adjust its adsorption angle, making it convenient to adsorb foreign objects on the edge or that have fallen off.

[0038] For details, please refer to the appendix. Figure 2 and attached Figure 3 The outer surfaces of the two connecting rods 303 are fitted with protective sleeves 301, which are fixedly installed on the outer surfaces of the two connecting rods 303. Multiple crushing blades 302 are installed obliquely on the outer surface of the protective sleeves 301.

[0039] By setting up a protective sleeve 301 and a crusher 302, the protective sleeve 301 protects and isolates the connecting rod 303, preventing foreign objects from entering between the connecting rods 303 and causing jamming and blockage. When the two connecting rods 303 vibrate up and down, they can drive the crusher 302 to vibrate up and down synchronously, crushing any foreign objects that enter, further preventing jamming and blockage.

[0040] For details, please refer to the appendix. Figure 1 and attached Figure 5 A camera and a light are fixed on the suction head 4 near the cleaning brush 304 and the cleaning needle 305. A display screen 5 for use with the camera is fixed on the mounting sleeve 201.

[0041] By setting up a camera, a light, and a display screen 5, both the light and the camera are equipped with transparent protective covers. Together with the display screen 5, they make it easier for medical staff to view the inside of the oral cavity and facilitate their operation.

[0042] Working principle: Place the adsorption rod 1 and adsorption head 4 in the patient's mouth, control the opening, and the electric push rod 7 drives the oral cavity bracket 8 to move. The position of the oral cavity bracket 8 can be adjusted. The oral cavity bracket 8 can support and lift the patient's mouth. Then control the opening of the adsorber 602, so that foreign objects in the oral cavity can enter the filter box 601 through the adsorption rod 1, and realize the adsorption and treatment of foreign objects in the oral cavity. When it is necessary to clean foreign objects from the teeth, the vibrator 204 is turned on. The vibrator 204 drives the guide plate 203 to vibrate. The vibration of the guide plate 203 drives the connecting rod 303 to vibrate through the ball stop 306. The vibration of the connecting rod 303 can drive the cleaning brush 304 and the cleaning needle 305 to vibrate synchronously, thereby achieving the cleaning of the teeth. At the same time, the upward movement of the limiting frame 202 drives the guide rod 206 away from the insertion hole, which can rotate the limiting frame 202. The rotation of the limiting frame 202 drives the guide frame to rotate and adjust its angle. The limiting frame 202 is released so that under the action of the elastic element 205, it moves downward and drives the guide rod 206 to insert into the insertion hole, thereby fixing the limiting frame 202. The rotating limit bracket 202 can drive the guide plate 203 to rotate. Since the guide plate 203 is tilted, when the guide plate 203 rotates, the two connecting rods 303 will slide inside the annular slide. At the same time, under the action of the ball stop 306, they will move up and down with the rotation of the guide plate 203, realizing the switching of the up and down position, realizing the replacement of the cleaning brush 304 and the cleaning needle 305. The cleaning brush 304 or the cleaning needle 305 can be selected for operation according to different usage needs.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
