Description

Technical Field

[0001] The invention relates to the technical field of oral medicine, and in particular to a dental pulp treatment device for oral medicine. Background Art

[0002] When the pulp of a tooth is infected or damaged, such as due to deep caries, trauma that exposes the pulp, excessive tooth wear, etc., the pulp tissue will become inflamed. If not treated in time, the inflammation will further spread to the tissues around the root tip, causing apical periodontitis. The purpose of root canal treatment is to remove the infected pulp tissue, clean the root canal system, prevent the infection from spreading further, and thus save the affected tooth.

[0003] Root canal treatment is usually divided into multiple stages, and the requirements for oral dilation in each stage are different. In the root canal preparation stage, a larger dilation range is required to facilitate instrument operation; while in the root canal filling stage, more emphasis may be placed on the stability and accuracy of the dilation, and the requirements for the dilation range are relatively small. However, the existing scissor-type dilators are difficult to fine-tune according to the characteristics of different treatment stages, and doctors can often only use the same dilation state to complete the entire treatment process.

[0004] In summary, how to solve the problem that the existing scissor-type distractors are difficult to fine-tune according to the characteristics of different treatment stages and doctors can only use the same distraction state to complete the entire treatment process has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a device for endodontic treatment in oral medicine. Summary of the invention

[0005] To solve the above problems, the present invention provides an endodontic treatment device for oral medicine, which is used to finely adjust the amplitude and state of oral expansion in different stages of root canal treatment according to different requirements for oral expansion in each stage, such as the need for a larger expansion amplitude in the root canal preparation stage and the requirement for expansion stability and accuracy in the root canal filling stage.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an oral endodontic treatment device for oral medicine, comprising an oral opening assembly for opening the patient's oral cavity, the oral opening assembly comprising a lower support rod, one end of the lower support rod is hingedly connected to an upper support rod, and both the lower support rod and the upper support rod are provided with sliding grooves; a sliding block is slidably fitted in the sliding groove of the lower support rod, a nut seat is slidably fitted in the sliding groove of the upper support rod, a screw rod is threadedly fitted in the nut seat, one end of the screw rod is rotatably fitted with the upper support rod, and the other end of the screw rod passes through the upper support rod and is coaxially fixedly connected with a hand-tightened piece.

[0007] A first connecting rod is hinged on one side wall of the upper support rod, and the first connecting rod is hinged on one end away from the upper support rod and the slider in the slide groove of the lower support rod; a second connecting rod is hinged on one side wall of the nut seat, and the second connecting rod is hinged on one end away from the nut seat and the first connecting rod is hinged on one end away from the upper support rod.

[0008] An upper tooth support and a lower tooth support are respectively fixedly connected to one side wall of the upper support rod and the lower support rod.

[0009] A flushing component for flushing the patient's oral cavity is provided on the top of the lower tooth tray.

[0010] The technical principles of the above scheme are as follows:

[0011] The patient bites the upper and lower tooth supports with his teeth, and the medical staff rotates the hand-tightened parts to drive the screw rod that is coaxially fixed to it to rotate. Due to the threaded cooperation between the screw rod and the nut seat, the nut seat will make a linear motion along the slide groove of the upper support rod. When the nut seat moves in the slide groove, the second connecting rod hinged to it will move accordingly, and the second connecting rod is hinged to the first connecting rod, thereby driving the first connecting rod to move. The other end of the first connecting rod is hinged to the slider in the slide groove of the lower support rod, so that the slider slides along the slide groove of the lower support rod. Under this series of linkage effects, the upper support rod and the lower support rod rotate relative to each other with the hinge point as the axis, thereby changing the angle of the upper support rod and the lower support rod, and then changing the distance between the upper and lower tooth supports, so as to adjust the degree of opening of the patient's mouth. Doctors can increase the distance between the upper and lower tooth trays according to different stages of root canal treatment, such as in the root canal preparation stage, by rotating the hand screw to obtain a larger opening range and facilitate instrument operation; in the root canal filling stage, the hand screw can be precisely adjusted to keep the upper and lower tooth trays at a suitable distance. The flushing assembly is arranged on the top of the lower tooth tray to facilitate flushing of the patient's mouth during treatment. The flushing pipe in the flushing assembly is connected to a pump assembly for extracting and supplying flushing liquid. The pump assembly flushes the inside of the mouth to remove debris and bacteria generated during treatment. At the same time, the sewage suction pipe sucks away the sewage and impurities after flushing. Sewage suction and flushing operations can be achieved using a pump assembly.

[0012] The above scheme has the following beneficial effects:

[0013] 1. The present invention realizes fine adjustment of the distance between the upper tooth support and the lower tooth support by rotating the hand-tightening part to drive the screw to rotate, and utilizing the threaded fit between the screw and the nut seat and the linkage of the connecting rod mechanism. This allows the doctor to change the amplitude and state of oral dilation at any time according to the different stages of root canal treatment, overcoming the defect that the existing scissor-type dilator can only be used in the same dilation state, and improving the convenience and accuracy of treatment.

[0014] 2. The present invention sets the flushing assembly on the top of the lower tooth tray, which can conveniently flush and suck out the patient's mouth while opening the mouth. Using one pump assembly to suck out and flush water simplifies the device structure, reduces the space occupied by the equipment, and improves the treatment efficiency.

[0015] 3. In the present invention, the upper support rod and the lower support rod are hingedly connected, and the slide block and the slide groove are designed to make the device move smoothly when adjusting the expansion range. In addition, the setting of the upper and lower tooth supports, combined with the self-locking characteristics of the screw and nut transmission, does not require an additional locking structure, simplifies the operation, and can ensure the stability of the expansion state in the stage where stability is required, such as root canal filling.

[0016] Furthermore, the flushing component includes a fixed block, to which a flushing pipe and a sewage suction pipe are fixedly connected, and the flushing pipe is connected to a pump component for extracting and supplying flushing liquid.

[0017] Beneficial effect: The support rod fixes the flushing pipe and the sewage suction pipe together, ensuring that the relative positions of the two in the oral cavity are stable, making it easy to perform flushing and sewage suction operations simultaneously.

[0018] Furthermore, the pump assembly includes a piston cylinder and a controller, a funnel-shaped upper bucket is fixedly connected to the top of the piston cylinder, and an inverted funnel-shaped lower bucket is fixedly connected to the bottom of the piston cylinder; an L-shaped bracket is fixedly connected to the side wall of the piston cylinder, and a base is fixedly connected to the bottom of the L-shaped bracket; a driving member is fixedly connected to the top of the horizontal end of the L-shaped bracket, and the controller is used to control the rotation of the output shaft of the driving member; the output shaft of the driving member passes through the L-shaped bracket and is fixedly connected to a "ㄑ"-shaped inclined rod, and the inclined rod is rotatably matched with a rotating shaft at one end away from the output shaft of the driving member, and a rotating ball is fixedly connected to the end of the rotating shaft away from the inclined rod, and the rotating ball is located between the upper bucket and the lower bucket, and the rotating ball is rotatably matched with the bottom of the upper bucket and the top of the lower bucket; a circular plate is fixedly connected to the rotating ball.

[0019] A partition is fixedly connected to the inner wall of the piston cylinder, and the partition is fixedly connected to both the upper bucket and the lower bucket; the partition penetrates the circular plate and slides with the circular plate, and the circular plate divides the piston cylinder into a first chamber and a second chamber arranged up and down; the rotating ball and the partition rotate in cooperation;

[0020] The flushing pipe is connected to the first chamber on one side of the partition, and the first chamber on the other side of the partition is connected to a water tank; the sewage suction pipe is connected to the second chamber on one side of the partition, and the second chamber on the other side of the partition is connected to a sewage tank.

[0021] Beneficial effects: The rotational motion of the driving member can be converted into a special piston motion of the circular plate in the piston cylinder, realizing the alternating change of the volume of the first chamber and the second chamber. When the volume of the first chamber increases, the sewage suction pipe can suck the sewage in the oral cavity; when the volume of the second chamber increases, the flushing liquid can be drawn from the water tank and transported to the oral cavity through the flushing pipe. Only one driving member is used to achieve the dual functions of suction and flushing, simplifying the structure of the device.

[0022] Furthermore, both the upper tooth support and the lower tooth support are covered with silicone sleeves.

[0023] Beneficial effects: The silicone sleeve is soft and elastic, and can fit the patient's teeth and gums, preventing the hard tooth tray from directly contacting the teeth and gums and causing damage or discomfort. At the same time, the silicone sleeve can also increase the friction with the teeth, making the tooth tray more firmly fixed in the mouth and preventing the device from shifting during treatment.

[0024] Furthermore, a mouth opening scale line is engraved on a wall of the upper support rod away from the upper tooth support.

[0025] Beneficial effect: The scale line provides doctors with a reference for the oral expansion range. When doctors adjust the hand-twisted parts to change the oral expansion range, they can accurately control the expansion degree according to the scale line to ensure that the expansion range meets the requirements of different stages of root canal treatment.

[0026] Furthermore, the outer surface of the hand-tightened part is engraved with anti-slip patterns.

[0027] Beneficial effect: The anti-slip texture increases the friction between the hand and the hand-twisted piece. When the doctor rotates the hand-twisted piece, the hand is not easy to slip and the operation is more stable.

[0028] Furthermore, the edge of the circular plate is arc-shaped.

[0029] Beneficial effects: The arc-shaped edge can reduce the frictional resistance between the circular plate and the partition plate and the cylinder wall when the circular plate moves in the piston cylinder, making the circular plate slide more smoothly. At the same time, the arc-shaped design can also reduce the wear on the inner wall of the piston cylinder and the partition plate.

[0030] Furthermore, the upper support rod and the lower support rod are both made of medical stainless steel.

[0031] Beneficial effects: Medical stainless steel has good corrosion resistance and strength, and can withstand various external forces generated during treatment without deformation. At the same time, it can also resist the erosion of oral fluids and chemicals.

[0032] Furthermore, the flushing pipe and the sewage suction pipe are both made of medical silicone material.

[0033] Beneficial effects: Medical silicone material has good flexibility and biocompatibility, and will not cause irritation or damage to oral tissue when used in the mouth. Its soft texture can also adapt to the complex spatial structure in the mouth, making it easy to adjust the position and direction of the pipe to ensure the flushing and suction operations.

[0034] Furthermore, the piston cylinder is made of a transparent material, and the transparent material includes polymethyl methacrylate and polycarbonate.

[0035] Beneficial effects: The transparent piston cylinder enables the doctor to clearly observe the flow of the internal liquid, whether there is any blockage by impurities, and the remaining amount of liquid.

[0036] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following is further described in detail through specific implementation methods:

[0044] Embodiment 1:

[0045] As attached Figure 1 and Figure 2 As shown: a device for oral endodontic treatment, including an oral opening component for opening the patient's oral cavity, the oral opening component including a lower support rod 1, one end of the lower support rod 1 is hinged to an upper support rod 2, and a slide groove is provided on the lower support rod 1 and the upper support rod 2; a slider 3 is slidably fitted in the slide groove of the lower support rod 1, a nut seat 4 is slidably fitted in the slide groove of the upper support rod 2, a screw rod 5 is internally threaded on the nut seat 4, one end of the screw rod 5 is rotatably fitted with the upper support rod 2, and the other end of the screw rod 5 passes through the upper support rod 2 and is coaxially integrally formed with a hand-tightening piece 6.

[0046] A first connecting rod 7 is hinged on one side wall of the upper support rod 2, and the first connecting rod 7 is hinged to the slider 3 in the slide groove of the lower support rod 1 at one end away from the upper support rod 2; a second connecting rod 8 is hinged on one side wall of the nut seat 4, and the second connecting rod 8 is hinged to the end away from the nut seat 4 and the end of the first connecting rod 7 away from the upper support rod 2.

[0047] An upper tooth support 9 and a lower tooth support 10 are formed integrally on one side wall of the upper support rod 2 and the lower support rod 1. The upper tooth support 9 and the lower tooth support 10 are both covered with a silicone sleeve.

[0048] A scale line for the oral opening is engraved on a side wall of the upper support rod 2 away from the upper tooth support 9 .

[0049] The outer surface of the hand-tightening member 6 is engraved with anti-skid patterns.

[0050] The upper support rod 2 and the lower support rod 1 are both made of medical stainless steel.

[0051] The specific implementation process is as follows:

[0052] The patient is asked to sit comfortably on the treatment chair and adjust the head to a suitable position for the doctor's operation. Then, the medical staff guides the patient to open his mouth, and the upper tooth support 9 and the lower tooth support 10 are respectively placed against the patient's upper teeth and lower teeth, and the patient is asked to bite gently to make the silicone sleeve fit the teeth. The silicone sleeve is soft and elastic, and can fit the patient's teeth and gums, avoiding direct contact between the hard tooth support and the teeth to cause damage or discomfort. At the same time, the silicone sleeve can also increase the friction with the teeth, making the upper tooth support 9 and the lower tooth support 10 more firmly fixed in the oral cavity, and preventing displacement during treatment.

[0053] by Figure 1 For example, according to the requirement of a larger opening range in the root canal preparation stage, the doctor pinches the hand screw 6 with his fingers and rotates it slowly. Since the outer surface of the hand screw 6 is engraved with anti-skid patterns, the doctor's fingers are not easy to slip, and the operation is more stable. At this time, the hand screw 6 drives the screw rod 5 to rotate, and since the screw rod 5 and the nut seat 4 are threaded, the nut seat 4 can move linearly along the slide groove on the upper support rod 2. When the doctor needs to open the patient's mouth, the nut seat 4 moves to the left, and the nut seat 4 can drive the second connecting rod 8 hinged thereto to rotate counterclockwise, so that the first connecting rod 7 rotates clockwise, driving the slider 3 to slide to the left, thereby increasing the angle between the upper support rod 2 and the lower support rod 1, so that the upper tooth support 9 and the lower tooth support 10 can open the patient's mouth to a larger extent; when the doctor twists the hand-screwed piece 6 in the opposite direction, the nut seat 4 can move to the right, and then drive the second connecting rod 8 to rotate clockwise, so that the first connecting rod 7 rotates counterclockwise, driving the slider 3 to move to the right, thereby reducing the angle between the upper support rod 2 and the lower support rod 1, so that the upper tooth support 9 and the lower tooth support 10 can open the patient's mouth to a smaller extent.

[0054] Since patients usually feel fear when undergoing oral surgery, they will subconsciously clench their mouths, which will increase the inconvenience of the doctor during the operation. When the patient subconsciously clenches his mouth due to fear, the self-locking characteristics of the screw rod 5 and the nut seat 4 can stably maintain the adjusted open state. For example, in the root canal preparation stage, the doctor has opened the mouth to a suitable extent to facilitate the operation of the instrument. Even if the patient suddenly clenched his mouth, the angles of the upper support rod 2 and the lower support rod 1 will not change due to the patient's bite force.

[0055] Embodiment 2:

[0056] As attached Figure 2-Figure 5 As shown, the difference from Embodiment 1 is that a flushing component for flushing the patient's oral cavity is provided on the top of the lower tooth tray 10 .

[0057] The flushing assembly includes a fixed block 11, to which a flushing pipe 12 and a sewage suction pipe 13 are fixedly connected. The flushing pipe 12 and the sewage suction pipe 13 are both made of medical silicone material. The flushing pipe 12 is connected to a pump assembly for extracting and supplying flushing liquid.

[0058] The pump assembly includes a piston cylinder 14 and a controller. A funnel-shaped upper bucket 15 is integrally formed on the top of the piston cylinder 14, and an inverted funnel-shaped lower bucket 16 is integrally formed on the bottom of the piston cylinder 14; an L-shaped bracket 17 is fixedly connected to the side wall of the piston cylinder 14 by screws, and a base 18 is fixedly connected to the bottom of the L-shaped bracket 17 by screws; a driving member 19 is fixedly connected to the top of the horizontal end of the L-shaped bracket 17 by screws, and the controller is used to control the rotation of the output shaft of the driving member 19; the output shaft of the driving member 19 passes through the L-shaped bracket 17 and is fixedly connected to a "ㄑ"-shaped inclined rod 20 by screws, and the inclined rod 20 is rotatably matched with a rotating shaft 21 at one end away from the output shaft of the driving member 19, and a rotating ball 22 is integrally formed at one end of the rotating shaft 21 away from the inclined rod 20, and the rotating ball 22 is located between the upper bucket 15 and the lower bucket 16, and the rotating ball 22 is rotatably matched with the bottom of the upper bucket 15 and the top of the lower bucket 16; a circular plate 23 is integrally formed on the rotating ball 22, and the edge of the circular plate 23 is arc-shaped.

[0059] A partition plate 24 is integrally formed on the inner wall of the piston cylinder 14, and the partition plate 24 is integrally formed with the upper bucket 15 and the lower bucket 16; the partition plate 24 passes through the circular plate 23 and slides with the circular plate 23, and the circular plate 23 divides the piston cylinder 14 into a first chamber 25 and a second chamber 26 arranged up and down; the rotating ball 22 and the partition plate 24 are rotatably matched.

[0060] The flushing pipe 12 is connected to the first chamber 25 on one side of the partition 24, and the first chamber 25 on the other side of the partition 24 is connected to the water tank; the sewage suction pipe 1 is connected to the second chamber 26 on one side of the partition 24, and the second chamber 26 on the other side of the partition 24 is connected to the sewage tank.

[0061] The piston cylinder 14 is made of a transparent material. In this embodiment, the transparent material is polymethyl methacrylate.

[0062] The specific implementation process is as follows:

[0063] by Figure 3 For example, an appropriate amount of flushing liquid is injected into the water tank, and the doctor uses the oral dilator assembly to dilate the oral cavity to an appropriate extent before performing the surgical operation; during the surgical operation, the pump assembly is used to flush the water pipe 12 and the sewage suction pipe 13 to clean the patient's teeth during the operation. When cleaning is required, since the flushing pipe 12 and the sewage suction pipe 13 are both made of medical silicone material with a soft texture, the doctor can use oral tweezers to clamp the flushing pipe 12 and the sewage suction pipe 13 and aim them at the part that needs to be flushed at the same time, and the doctor uses the controller to control the rotation of the output shaft of the driving member 19. In this embodiment, the driving member 19 is a DC motor; at this time, the rotation of the output shaft of the DC motor drives the "ㄑ"-shaped inclined rod 20 to rotate, and the inclined rod 20 drives the rotating ball 22 to rotate between the upper bucket 15 and the lower bucket 16 through the rotating shaft 21, and the circular plate 23 integrally formed on the rotating ball 22 then performs piston movement in the piston cylinder 14.

[0064] by Figure 4 and Figure 5 For example, when the circular plate 23 moves from a "\" shape to a " / " shape, the volume of the left part of the first chamber 25 increases, and the left part of the first chamber 25 can generate negative pressure. Since the left part of the first chamber 25 is connected to a water tank, the negative pressure can suck the water in the water tank into the left part of the first chamber 25. When the circular plate 23 moves from a " / " shape to a "\" shape, the volume of the left part of the first chamber 25 decreases, and positive pressure is generated. At this time, the circular plate 23 can drive the water to the right part of the first chamber 25, and then spray the water from the flushing pipe 12 to the position in the patient's mouth that needs to be cleaned, so as to flush the debris, blood and bacteria generated during the operation; driven by the continuous up and down reciprocating motion of the circular plate 23, water can be continuously pumped from the water tank to the position that needs to be cleaned, so that the oral cavity opening component can support the patient's mouth while flushing the patient's mouth.

[0065] Likewise Figure 4 and Figure 5 For example, when the circular plate 23 moves from the “ / ” shape to the “\” shape, the volume of the left part of the second chamber 26 increases. At this time, the left part of the second chamber 26 can generate negative pressure. Since the left part of the second chamber 26 is connected to the sewage suction pipe 13, the sewage suction pipe 13 can suck the flushed sewage and impurities into the left part of the second chamber 26.

[0066] When the circular plate 23 moves from the "\" shape to the " / " shape, the volume of the left part of the second chamber 26 decreases, and the volume of the right part of the second chamber 26 increases. At this time, the sewage can enter the right part of the second chamber 26 and then be discharged into the sewage box connected to the right part of the second chamber 26. Driven by the continuous up and down reciprocating motion of the circular plate 23, the sewage and impurities can be continuously sucked from the patient's mouth into the sewage box, achieving the effect of simultaneously absorbing sewage while flushing water, using one pump assembly to achieve sewage absorption and flushing water, simplifying the device structure, reducing the space occupied by the equipment, and improving the treatment efficiency.

[0067] Doctors can adjust the speed of the DC motor through the controller according to the actual situation of the operation, thereby controlling the flow rate and flow of the flushing water to achieve the best flushing effect.

[0068] During the flushing process, the doctor can observe the flow of the internal liquid through the transparent piston cylinder 14 made of polymethyl methacrylate. If impurities are found to be blocked, the doctor can stop the DC motor in time and clean the pump assembly.

[0069] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
