Description

Technical Field

[0001] The present invention mainly relates to the technical field of oral mirrors, and specifically to an intelligent oral mirror for oral diagnosis and treatment. Background Art

[0002] With the awakening of people's health awareness, more and more people have begun to pay attention to their own all-round health issues. Teeth, as important organs for chewing and eating, assist in the supply of nutrition to the body. In addition, teeth can cooperate with the tongue to assist people in pronunciation accurately and reduce the problem of inaccurate pronunciation caused by air leakage due to lack of teeth. They play an important role in people's lives. When conducting dental examinations and treatments, oral medical workers usually need to use oral mirrors to assist in observing the specific conditions in the patient's mouth for diagnosis and treatment.

[0003] An oral endoscope is a conventional inspection instrument that is widely used in the clinical diagnosis of oral diseases. A traditional oral endoscope generally includes a handle and a convex mirror that is tilted at one end of the handle. During oral treatment, a lot of saliva will form in the patient's mouth, and the humidity of the oral gas during exhalation or the debris and moisture during drilling and grinding can cause the mirror surface to fog or become unclear, making it inconvenient for doctors to observe. As a result, some oral mirrors with saliva suction devices have appeared on the market, that is, a saliva suction port is opened at the end of the oral mirror, and the saliva suction port is connected to the connecting tube built into the handle, and the connecting tube is connected to the water circuit and circuit on the external dental chair. The saliva is absorbed by the adsorption force of the saliva suction port, and the water mist on the mirror surface is sucked away at the same time.

[0004] In order to allow dental medical staff to better observe the patient's oral cavity, the lens used in the dental mirror is basically a convex mirror. After the dental mirror is inserted into the patient's mouth, the medical staff will constantly turn the dental mirror to adjust the angle to achieve the best observation angle. Therefore, the dental mirror is in a tilted state in most cases, that is, the convex mirror is tilted, such as the figure in the manual. Figure 1 , which is a cross-sectional view of the oral mirror when tilted, and includes a frame 101, a convex mirror 102 disposed inside the frame 101, and a plurality of saliva suction ports 103 disposed on the inner side of the frame 101. If the patient's saliva falls on the drawing of the specification Figure 1 When it is at the position of the middle arrow, it is difficult to slide downwards into the lower saliva suction port, and it is also difficult to move upwards into the upper saliva suction port. In addition, the adhesion of saliva itself makes the saliva stay in place, which greatly affects the observation of medical staff. Summary of the invention

[0005] The technical solution of the present invention aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. Specifically, the present invention mainly provides an intelligent dental mirror for oral diagnosis and treatment, which is used to solve the technical problems raised in the above background technology.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: A smart oral mirror for oral diagnosis and treatment, comprising a handle and a mirror frame head connected to each other, and a convex lens installed inside the mirror frame head, wherein a ring plate is rotatably arranged inside the mirror frame head, and the ring plate is located above the convex lens, and the left and right sides of the ring plate are respectively connected to a plurality of saliva suction tubes and a plurality of air blowing tube groups, each of the air blowing tube groups comprises a lower tube with a tube opening obliquely upward and an upper tube with a tube opening obliquely downward; A cavity is provided inside the frame head, and a counterweight half ring and a hollow half ring connected to each other are provided inside the cavity. A plurality of equidistantly arranged adjustment components are installed on the hollow half ring, and each of the adjustment components includes a mounting plate, and a driving wheel and a driven wheel are rotatably installed on one side of the mounting plate, as well as a sliding frame and an adjustment box are fixedly installed. The driving wheel and the driven wheel are connected by a friction belt transmission, and a vertical weight rod is connected to the side of the driving wheel. A moving rod is slidably provided on the sliding frame, and a connecting rod is rotatably connected to the side of the moving rod and the driven wheel at an eccentric position. A pushing rod is slidably provided on the moving rod, and the other ends of the lower tube and the upper tube extend into the interior of the adjustment box. A combination plate that slides at the pipe mouths of the lower tube and the upper tube is provided inside the adjustment box, and the pushing rod extends into the adjustment box and is connected to the combination plate.

[0007] Preferably, a pressure sensor is provided on the back side of the convex lens.

[0008] Preferably, a straw and a blow pipe are provided inside the handle, and the straw and the blow pipe pass through the handle, an upper box body and a lower box body are rotatably provided at the upper and lower ends of the center of the cavity, the straw is connected to the upper box body through a rotating joint, and the blow pipe is connected to the lower box body through a rotating joint.

[0009] Preferably, the counterweight half ring and the hollow half ring are installed on the side wall of the lower box body through a plurality of connecting rods, the counterweight half ring and the hollow half ring form a complete circular ring, and the axis line of the lower box body coincides with the axis line of the complete circular ring.

[0010] Preferably, the plurality of saliva suction tubes are all connected to the upper box body, one side of the regulating box is connected to an air inlet pipe, and the other end of the air inlet pipe is connected to the lower box body.

[0011] Preferably, the combined plate includes a central vertical plate and movable plates arranged on both sides of the vertical plate, each of the movable plates is connected to the vertical plate with an elastic telescopic rod, and when the movable plate and the vertical plate are connected, a vent is formed between the movable plate and the vertical plate.

[0012] Preferably, a guide tube is rotatably provided inside the regulating box, a counterweight piston is slidably provided inside the guide tube, and the guide tube is connected to the elastic telescopic rod through a hose penetrating the vertical plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) The blowpipe delivers the airflow to the lower box body, and then the airflow enters the interior of each adjustment box through each air inlet pipe, and then flows out through the lower pipe and the upper pipe to blow air to the surface of the convex lens. At the same time, the suction pipe generates suction, so that the saliva suction tube also has suction. The blowing and suction are carried out simultaneously, which can not only quickly remove the saliva and water mist on the convex lens, but also form an airflow protection layer on the surface of the convex lens, making it more difficult for water mist to be generated and saliva to fall to the center of the convex lens, making it easier to clean the saliva; and because the lower pipe opening is inclined upward and the upper pipe opening is inclined downward, the airflow direction is easier to fit the upper side of the convex lens, so it is easier to clean the saliva.

[0014] (2) When the convex lens is horizontal, the airflow blown out of the lower tube is used to send saliva from the low point of the convex lens to the high point, and the airflow blown out of the upper tube is used to send saliva from the high point of the convex lens to the low point and allow the saliva to enter the saliva suction tube. Since the saliva is sent from the high point of the convex lens to the low point, it will not only be assisted by gravity, but also by suction. Therefore, the air flow of the lower tube should be larger than that of the upper tube in order to achieve reasonable utilization of resources. At this time, the combination plate does not block the lower tube, but blocks most of the upper tube opening, so that most of the airflow inside the adjustment box enters the lower tube, thereby improving the demisting and saliva removal effects while reducing the air flow consumption, so that the oral mirror can intelligently allocate resources and improve the use effect.

[0015] (3) When the convex lens rotates, since the counterweight half ring is much heavier than the hollow half ring, the counterweight half ring will always be below the level of the hollow half ring, so that the blowpipe will always be above the level of the suction pipe, so that when removing saliva, the gravity of the saliva will be used to assist the saliva removal operation, which is more convenient for saliva removal and reduces the air flow consumption; at the same time, since the vertical weight rod will always be perpendicular to the horizontal plane, as the convex lens rotates, the driving wheel will rotate and drive the driven wheel to rotate. The rotation of the driven wheel will push the moving rod to move, so that the pushing rod pushes the combination plate to move, so that the combination plate gradually blocks the lower tube opening and gradually reduces the blocking of the upper tube opening, thereby avoiding the large lower tube airflow directly blowing the saliva on the convex lens away from the convex lens when the convex lens is tilted, so that the saliva returns to the patient's mouth and affects the treatment effect of medical staff. The present oral mirror can intelligently allocate resources and improve the use effect.

[0016] (4) When the pressure sensor suddenly detects that the convex lens is suddenly subjected to a large pressure, that is, a large volume of saliva suddenly falls on the convex lens and covers the convex lens, at this time, the restoration of the convex lens (removal of saliva from the convex lens) should be the first task, and the impact of the large airflow on the treatment work of medical staff should be ignored for a short period of time. The air flow rate should be increased strongly. Since there is a large amount of gas inside the adjustment box, the air pressure continues to rise, causing the counterweight piston inside the guide tube to move upward, squeezing the gas inside the guide tube into each elastic telescopic rod, causing the elastic telescopic rod to extend, and the moving plate and the vertical plate to separate, ensuring that the combined plate will not cause any obstruction to the lower and upper tube openings, so that the airflow impact force of the lower and upper tubes reaches the maximum, and the saliva on the convex lens is removed as quickly as possible, so that the oral mirror can respond to emergencies intelligently.

[0020] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0023] Example 1: Please refer to the attached Figure 2 - Figure 4 A smart oral mirror for oral diagnosis and treatment includes a handle 4 and a mirror frame head 3 connected to each other, and a convex lens 2 installed inside the mirror frame head 3. A ring plate 301 is rotatably arranged inside the mirror frame head 3, and the ring plate 301 is located above the convex lens 2. A plurality of saliva suction tubes 302 and a plurality of air blowing tube groups are connected to the left and right sides of the ring plate 301, respectively. Each air blowing tube group includes a lower tube 303 with an oblique upward orifice and an upper tube 304 with an oblique downward orifice. Since the orifice of the lower tube 303 is obliquely upward and the orifice of the upper tube 304 is obliquely downward, the airflow direction is easier to fit the upper side of the convex lens 2, so it is easier to clean saliva.

[0024] Please refer to the attached Figure 2 - Figure 5, a cavity is provided inside the frame head 3, a counterweight half ring 307 and a hollow half ring 308 are connected inside the cavity, a plurality of equally spaced adjustment components are installed on the hollow half ring 308, each adjustment component includes a mounting plate 309, a driving wheel 310 and a driven wheel 311 are rotatably installed on one side of the mounting plate 309, and a sliding frame 313 and an adjustment box 315 are fixedly installed, the driving wheel 310 and the driven wheel 311 are connected by a friction belt transmission, and the side of the driving wheel 310 is connected with a vertical A straight weight rod 312, a moving rod 314 slides on the sliding frame 313, the moving rod 314 and the driven wheel 311 are rotatably connected with a connecting rod at an eccentric position on the side, a pushing rod 320 is slidably installed on the moving rod 314, the other ends of the lower tube 303 and the upper tube 304 extend to the inside of the adjusting box 315, and a combination plate 316 that slides at the pipe mouth position of the lower tube 303 and the upper tube 304 is arranged inside the adjusting box 315, and the pushing rod 320 extends into the adjusting box 315 and is connected to the combination plate 316. When the convex lens 2 is horizontal, the airflow blown out of the lower tube 303 is used to send the saliva from the low point of the convex lens 2 to the high point, and the airflow blown out of the upper tube 304 is used to send the saliva from the high point of the convex lens 2 to the low point and allow the saliva to enter the saliva suction tube 302. Since the saliva is sent from the high point of the convex lens 2 to the low point, it will not only be assisted by gravity, but also by suction. Therefore, the airflow of the lower tube 303 should be larger than that of the upper tube 304 to achieve reasonable utilization of resources. At this time, the combined plate 316 does not block the lower tube 303, but blocks most of the tube openings of the upper tube 304, so that most of the airflow inside the adjustment box 315 enters the lower tube 303, thereby improving the defog and saliva removal effects while reducing the airflow consumption. Please refer to the attached Figure 2 - Figure 5A suction pipe 401 and a blow pipe 402 are arranged inside the handle 4, and the suction pipe 401 and the blow pipe 402 pass through the handle 4, and an upper box body 305 and a lower box body 306 are rotatably arranged at the upper and lower ends of the center of the cavity, the suction pipe 401 is connected to the upper box body 305 through a rotating joint, and the blow pipe 402 is connected to the lower box body 306 through a rotating joint, and a counterweight semi-ring 307 and a hollow semi-ring 308 are installed on the side wall of the lower box body 306 through a plurality of connecting rods, and the counterweight semi-ring 307 and the hollow semi-ring 308 form a complete circular ring, and the axis line of the lower box body 306 coincides with the axis line of the complete circular ring, and a plurality of saliva suction tubes 302 are all connected to the upper box body 305, and an air inlet pipe 317 is connected to one side of the adjustment box 315, and the other end of the air inlet pipe 317 is connected to the lower box body 306. When the convex lens 2 rotates, since the weighted semi-ring 307 is much heavier than the hollow semi-ring 308, the weighted semi-ring 307 will always be below the level of the hollow semi-ring 308, so that the blowpipe 402 will always be above the level of the suction pipe 401, so that when saliva is removed, the gravity of the saliva can be used to assist the saliva removal operation, which is more convenient for saliva removal and reduces the air flow consumption; at the same time, since the vertical weight rod 312 is always perpendicular to the horizontal plane, when the convex lens 2 rotates, The driving wheel 310 rotates and drives the driven wheel 311 to rotate. The rotation of the driven wheel 311 pushes the moving rod 314 to move, so that the pushing rod 320 pushes the combined plate 316 to move, so that the combined plate 316 gradually blocks the tube opening of the lower tube 303 and gradually reduces the blocking of the tube opening of the upper tube 304, thereby preventing the larger airflow of the lower tube 303 from directly blowing the saliva on the convex lens 2 away from the convex lens 2 when the convex lens 2 is tilted, so that the saliva returns to the patient's mouth and affects the treatment effect of the medical staff. Example 2: Based on Example 1, please refer to the attached Figure 3 A pressure sensor 201 is provided on the back of the convex lens 2. The pressure sensor 201 is electrically connected to the master control circuit on the external dental chair. The master control circuit can be realized by simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection will not be described in detail.

[0025] Please refer to the attached Figure 2 - Figure 6The combined plate 316 includes a central vertical plate 3161 and movable plates 3162 arranged on both sides of the vertical plate 3161. Each movable plate 3162 is connected to the vertical plate 3161 by an elastic telescopic rod 3163. When the movable plate 3162 is connected to the vertical plate 3161, a vent 3164 is formed between the movable plate 3162 and the vertical plate 3161. A guide tube 318 is rotatably arranged inside the adjustment box 315, and a counterweight piston 319 is slidably arranged inside the guide tube 318. The guide tube 318 is connected to the elastic telescopic rod 3163 through a hose that penetrates the vertical plate 3161. When the pressure sensor 201 suddenly detects that the convex lens 2 is suddenly subjected to a large pressure, that is, a large volume of saliva suddenly falls on the convex lens 2 and covers the convex lens 2, at this time, the first task should be to restore the vision of the convex lens 2 (remove saliva from the convex lens 2), and the influence of the large airflow on the treatment work of the medical staff should be ignored for a short period of time, and the airflow should be increased strongly. Since there is a large amount of gas inside the adjustment box 315, the air pressure continues to rise, causing the counterweight piston 319 inside the guide tube 318 to move upward, squeezing the gas inside the guide tube 318 into each elastic telescopic rod 3163, so that the elastic telescopic rod 3163 is extended, and the movable plate 3162 and the vertical plate 3161 are separated, ensuring that the combined plate 316 will not cause any obstruction to the lower tube 303 and the upper tube 304, so that the airflow impact force of the lower tube 303 and the upper tube 304 reaches the maximum, and the saliva on the convex lens 2 is removed as quickly as possible. Specific steps: The oral mirror is connected to the water circuit and the circuit on the external dental chair, and the suction tube 401 and the blowpipe 402 are respectively connected to the suction port and the air outlet of the suction pump on the external dental chair. The medical staff holds the handle 4 to hold the oral mirror, and then inserts the mirror head 3 into the patient's mouth, and rotates the handle 4 to rotate the convex lens 2 until the patient's oral disease site is found. The medical staff holds the oral mirror in one hand to observe the patient's oral disease site, and uses the other hand to treat the patient's oral disease site with a medical device; When the medical staff observes through the oral mirror, the blowing tube 402 sends the airflow into the lower box body 306, and then the airflow enters the inside of each adjustment box 315 through each air inlet pipe 317, and then flows out through the lower tube 303 and the upper tube 304, blowing air on the surface of the convex lens 2. At the same time, the suction tube 401 generates suction, so that the saliva suction tube 302 also has suction. Blowing and sucking are carried out simultaneously, which can not only quickly take away the saliva and water mist on the convex lens 2, but also form an airflow protection layer on the surface of the convex lens 2, making it more difficult for water mist to be generated and saliva to fall into the center of the convex lens 2, making it easier to clean the saliva; Because the opening of the lower tube 303 is inclined upward and the opening of the upper tube 304 is inclined downward, the airflow direction is easier to fit with the upper side of the convex lens 2, so it is easier to clean saliva; when the convex lens 2 is horizontal, the airflow blown out of the lower tube 303 is used to send the saliva from the low point of the convex lens 2 to the high point, and the airflow blown out of the upper tube 304 is used to send the saliva from the high point of the convex lens 2 to the low point and allow the saliva to enter the saliva suction tube 302. Since the saliva is sent from the high point of the convex lens 2 to the low point, it will not only be assisted by gravity but also by suction. Therefore, the airflow of the lower tube 303 should be larger than that of the upper tube 304 to achieve reasonable use of resources. At this time, the combined plate 316 does not block the lower tube 303, but blocks most of the openings of the upper tube 304, so that most of the airflow inside the adjustment box 315 enters the lower tube 303, thereby improving the demisting and saliva removal effects while reducing airflow consumption; When the convex lens 2 rotates, since the weighted semi-ring 307 is much heavier than the hollow semi-ring 308, the weighted semi-ring 307 will always be below the level of the hollow semi-ring 308, so that the blowpipe 402 will always be above the level of the suction pipe 401, so that when saliva is removed, the gravity of the saliva can be used to assist the saliva removal operation, which is more convenient for saliva removal and reduces the air flow consumption; at the same time, since the vertical weight rod 312 is always perpendicular to the horizontal plane, when the convex lens 2 rotates, The driving wheel 310 rotates and drives the driven wheel 311 to rotate. The rotation of the driven wheel 311 pushes the moving rod 314 to move, so that the pushing rod 320 pushes the combined plate 316 to move, so that the combined plate 316 gradually blocks the tube opening of the lower tube 303 and gradually reduces the blocking of the tube opening of the upper tube 304, thereby preventing the larger airflow of the lower tube 303 from directly blowing the saliva on the convex lens 2 away from the convex lens 2 when the convex lens 2 is tilted, so that the saliva returns to the patient's mouth and affects the treatment effect of the medical staff; When the pressure sensor 201 suddenly detects that the convex lens 2 is suddenly subjected to a large pressure, that is, a large volume of saliva suddenly falls on the convex lens 2 and covers the convex lens 2, at this time, the first task should be to restore the vision of the convex lens 2 (remove saliva from the convex lens 2), and the influence of the large airflow on the treatment work of the medical staff should be ignored for a short period of time, and the airflow should be increased strongly. Since there is a large amount of gas inside the adjustment box 315, the air pressure continues to rise, causing the counterweight piston 319 inside the guide tube 318 to move upward, squeezing the gas inside the guide tube 318 into each elastic telescopic rod 3163, so that the elastic telescopic rod 3163 is extended, and the movable plate 3162 and the vertical plate 3161 are separated, ensuring that the combined plate 316 will not cause any obstruction to the lower tube 303 and the upper tube 304, so that the airflow impact force of the lower tube 303 and the upper tube 304 reaches the maximum, and the saliva on the convex lens 2 is removed as quickly as possible, and reset after completion.

[0026] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
