Description

Technical Field

[0001] The present invention relates to the technical field of oral medical instruments, and in particular to a supporting device for oral diseases. Background Art

[0002] Oral diseases are widespread among the population, including dental caries, periodontitis, oral mucosal diseases and many other types. These diseases not only affect patients' chewing, swallowing and language functions, but may also have adverse effects on overall health. In the treatment of oral diseases, whether it is routine filling, tooth extraction, or complex oral and maxillofacial surgery, reliable support devices are required to maintain the specific shape and position of the oral cavity, provide medical staff with a clear operating field of view, and ensure smooth treatment.

[0003] In recent years, domestic research on support devices for oral diseases has also made some progress. Many universities and research institutions have cooperated with dental hospitals to carry out research and development of related technologies. Some oral support devices are designed based on the occlusal relationship of the upper and lower teeth. They are usually made of brackets and soft materials. When the patient wears them, the support device is placed between the upper and lower teeth, and the patient's upper and lower teeth bite on the soft material on the bracket to maintain the open state of the mouth.

[0004] Numerous retrospective studies have analyzed a large number of oral surgery cases and found that the postoperative infection rate is closely related to the bacteria in the saliva. For example, a study of patients after tooth extraction showed that patients with high saliva content in their mouths before surgery had a significantly higher probability of postoperative infection than patients with low saliva content. Another retrospective study on oral and maxillofacial surgery found that the types of pathogens detected in saliva in infected cases were more complex, and the proportion of drug-resistant bacteria was higher. Therefore, when patients undergo oral surgery, reducing the saliva content in the patient's mouth is important for inhibiting postoperative infection.

[0005] However, the support device currently used in clinical practice will stimulate the patient's oral mucosa as the medical staff operates in the patient's mouth during the process of stretching the patient's mouth, causing the patient to continuously secrete saliva in the mouth. The continuous secretion of saliva not only easily blurs the surgical field of view and interferes with the medical staff's observation and operation of the oral lesions, but also because the residual saliva in the mouth often contains a large number of bacteria, the patient's immunity is reduced after surgery, which is prone to oral infection and prolonging the patient's recovery period. Summary of the invention

[0006] The purpose of the present invention is to overcome the problems in the prior art and provide a support device for oral diseases, which can prevent the saliva in the patient's mouth from affecting the operation of medical staff when supporting the patient's mouth and reduce the risk of infection after oral surgery.

[0032] The following combines the attached Figures 1-6 , and describes in detail the specific implementation manners of the present invention. However, it should be understood that the protection scope of the present invention is not limited by the specific implementation manners. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1-6 shown, a support device for oral diseases provided by the present invention, the support device for oral diseases includes a bracket 101, an upper support plate 102 and a lower pressing plate 103. The upper support plate 102 and the lower pressing plate 103 are both connected to the bracket 101 and are both arc-shaped structures. The upper support plate 102 abuts against the upper teeth of the patient. It further includes: a straw 104, a suction pump, a slide bar 107, a stop block 108 and a first spring 106. The straw 104 is vertically arranged on the concave side of the lower pressing plate 103. The lower pressing plate 103 is provided with a first liquid passage hole 105. The top end of the straw 104 is communicated with the first liquid passage hole 105; the suction pump is communicated with the straw 104 through the first liquid passage hole 105; the slide bar 107 is vertically arranged on the lower pressing plate 103. The bracket 101 is provided with a vertical slide hole, and the slide bar 107 is slidably connected in the slide hole in the vertical direction; the stop block 108 is arranged at the bottom end of the slide bar 107; the first spring 106 is arranged outside the slide bar 107. The lower end of the first spring 106 abuts against the stop block 108. The first spring 106 is used to apply a vertically downward elastic force to the slide bar 107. Under the action of the elastic force of the first spring 106, the lower pressing plate 103 is pressed tightly against the lower teeth of the patient, and the bottom end of the straw 104 is attached to the inner side of the lower jaw of the patient's oral cavity.

[0034] Now briefly describe the working principle of the above embodiments:

[0035] When the device is in use, the patient's chin rests on the bracket 101. The patient opens the mouth, then the upper support plate 102 is abutted against the patient's upper teeth, and then the lower pressing plate 103 is pulled upward. The lower pressing plate 103 drives the sliding rod 107 to move upward, thereby driving the stopper 108 to move upward. The stopper 108 presses the first spring 106, and the first spring 106 is compressed under pressure until the upper pressing plate is higher than the patient's lower teeth. Then, the lower pressing plate 103 is released. Under the action of the elastic force of the spring, the lower pressing plate 103 moves downward until the lower pressing plate 103 presses tightly on the patient's lower teeth, and the bottom end of the straw 104 fits against the inner side of the patient's oral cavity at the lower jaw. There is a gap between the upper support plate 102 and the lower pressing plate 103, thus leaving an operation window for medical staff. Then, the suction pump is turned on, and the suction pump sucks the inner side of the patient's oral cavity at the lower jaw through the straw 104 and the first liquid passage hole 105, thereby sucking the saliva secreted by the patient clean.

[0036] The support device for oral diseases of the present invention can support the patient's oral cavity to facilitate medical staff to perform surgical operations on the patient's oral cavity, and can also timely suck the saliva in the patient's oral cavity, thereby sucking the saliva secreted in the patient's oral cavity clean, preventing the saliva in the patient's oral cavity from affecting the operation of medical staff, and reducing the risk of infection after the patient's oral surgery.

[0037] On the basis of the above embodiment, in order to suck the saliva in the patient's oral cavity more thoroughly.

[0038] As Figure 1 、 Figure 3 、 Figure 4 and Figure 6 shown, wherein, a cylinder body 201 is further provided between the straw 104 and the lower pressing plate 103. The cylinder body 201 is vertically arranged, and a second spring 202 is arranged in the inner cavity of the cylinder body 201. The top end of the straw 104 is slidably connected in the inner cavity of the cylinder body 201. The bottom end of the second spring 202 abuts against the top end of the straw 104. The second spring 202 is used to apply a downward elastic force to the straw 104. The side wall of the bottom end of the straw 104 is provided with a suction port 203. The suction port 203 is communicated with the tube hole of the straw 104. The bottom end of the tube hole of the straw 104 is closed.

[0039] During the process of releasing the lower pressing plate 103, when the straw 104 has not yet contacted the lower jaw part inside the patient's oral cavity, under the action of the elastic force of the second spring 202, the lower end of the straw 104 extends out of the inner cavity of the cylinder body 201. As the lower pressing plate 103 moves downward, the straw 104 also moves downward until the straw 104 contacts the lower jaw part inside the patient's oral cavity first. Supported by the patient's lower jaw part, the straw 104 is squeezed into the inside of the cylinder body 201. Under the extrusion of the top end of the straw 104, the second spring 202 is compressed. The elastic force exerted by the second spring 202 on the straw 104 enables the bottom end of the straw 104 to fit against the lowest point of the patient's lower jaw part until the lower pressing plate 103 is pressed tightly against the patient's lower teeth. When the bottom end of the straw 104 fits against the lowest point of the patient's lower jaw part, since the lower jaw part is the lowest end inside the patient's oral cavity, the saliva inside the patient's oral cavity can be sucked more thoroughly. And closing the bottom end of the tube hole of the straw 104 can prevent the bottom end of the tube hole of the straw 104 from directly contacting the inner mucosa of the patient's lower jaw part, thereby preventing the negative pressure inside the tube hole of the straw 104 from causing harm to the inner mucosa of the patient's lower jaw part.

[0040] As a preferred solution, as Figure 1 and Figure 4 shown, wherein, a second liquid passage hole 301 is provided on the upper support plate 102, and a plurality of first spray nozzles 302 are provided on one concave side wall of the upper support plate 102. The plurality of first spray nozzles 302 are all communicated with the second liquid passage hole 301. A third liquid passage hole 303 is provided on the lower pressing plate 103, and a plurality of second spray nozzles 304 are provided on one concave side wall of the lower pressing plate 103. The plurality of second spray nozzles 304 are all communicated with the third liquid passage hole 303. The second liquid passage hole 301 and the third liquid passage hole 303 are communicated with a liquid supply device, and the liquid supply device is used to supply cleaning liquid to the second liquid passage hole 301 and the third liquid passage hole 303. Before sucking the saliva inside the patient's oral cavity, by controlling the operation of the liquid supply device, the liquid supply device injects cleaning liquid into the second liquid passage hole 301 and the third liquid passage hole 303. A part of the cleaning liquid is sprayed out from the plurality of first spray nozzles 302 through the second liquid passage hole 301 to wash the upper half of the patient's oral cavity, and another part of the cleaning liquid is sprayed out from the plurality of second spray nozzles 304 through the third liquid passage hole 303 to wash the lower half of the patient's oral cavity. Under the spraying of the plurality of first spray nozzles 302 and the plurality of second spray nozzles 304, combined with the suction of the straw 104, the residual saliva inside the patient's oral cavity can be cleaned up, further reducing the risk of infection after the patient's oral surgery.

[0041] As a preferred solution, as Figures 1-5As shown in the figure, a chute 401 is provided on both the upper support plate 102 and the lower pressing plate 103. A guard plate 403 is provided on both the upper support plate 102 and the lower pressing plate 103. The guard plate 403 abuts against the upper teeth or lower teeth of the patient. A slider 404 is connected to the guard plate 403. The slider 404 is slidably connected in the chute 401 in the vertical direction. An elastic block 402 is provided in the chute 401. The elastic block 402 abuts against the slider 404. A guide hole 405 is provided on the guard plate 403. The guide hole 405 communicates with the first spray port 302 or the second spray port 304. When the guard plate 403 moves in the vertical direction, the direction of the cleaning liquid sprayed from the guide hole 405 changes. By providing the guard plate 403, when the cleaning liquid sprayed from the first spray port 302 and the second spray port 304 sprays and washes the inside of the patient's oral cavity, the patient intermittently presses the guard plate 403 with the teeth. Under the action of the elastic force of the elastic block 402, the guard plate 403 drives the slider 404 to reciprocate in the chute 401 in the vertical direction, so as to change the position of the guide hole 405 on the guard plate 403 relative to the first spray port 302 or the second spray port 304, thereby changing the direction of the cleaning liquid sprayed from the first spray port 302 or the second spray port 304, so that the cleaning liquid sprayed from the first spray port 302 and the second spray port 304 can spray and wash the inside of the patient's oral cavity in all directions, thereby further cleaning the remaining saliva in the patient's oral cavity completely.

[0042] As a preferred solution, as Figure 1 and Figure 5As shown in the figure, the liquid supply device is communicated with the second liquid passage hole 301. A female docking head 501 is provided on the upper support plate 102, and the female docking head 501 is communicated with the second liquid passage hole 301. A male docking head 502 is provided on the lower pressing plate 103, and the male docking head 502 is communicated with the third liquid passage hole 303. A lifting mechanism is provided on the upper support plate 102, and the lifting mechanism is used to adjust the distance between the upper support plate 102 and the lower pressing plate 103. When the upper support plate 102 and the lower pressing plate 103 are attached, the male docking head 502 is docked and communicated with the female docking head 501. By providing the male docking head 502 and the female docking head 501, initially, by controlling the lifting mechanism to act, the lifting mechanism drives the upper support plate 102 to move towards the lower pressing plate 103 until the upper support plate 102 is attached to the lower pressing plate 103. At this time, the male docking head 502 on the lower pressing plate 103 is inserted into the female docking head 501 on the upper support plate 102 and is communicated. At this time, the liquid supply device is controlled to introduce cleaning liquid into the second liquid passage hole 301. Part of the cleaning liquid is sprayed out through the first spray port 302 communicated with the second liquid passage hole 301, and the other part of the cleaning liquid enters the third liquid passage hole 303 through the female docking head 501 and the male docking head 502, and then is sprayed out through the second spray port 304, so as to wash the patient's oral cavity; after the saliva in the patient's oral cavity is sucked clean, the liquid supply device is closed, and the upper support plate 102 is driven to move upward by the lifting mechanism, so as to increase the distance between the upper support plate 102 and the lower pressing plate 103, so as to leave an operation space for medical staff. At the same time, the male docking head 502 is separated from the female docking head 501. During the operation, the cleaning liquid is introduced into the second liquid passage hole 301 through the liquid supply device, so as to wash the patient's oral cavity through the first spray port 302, and then by controlling the suction pump to act, the patient's oral cavity can be intermittently washed to keep the patient's oral cavity clean at all times.

[0043] As a preferred solution, as Figure 5As shown in the figure, the female docking head 501 includes a sliding cavity 601 and a plug 602. The sliding cavity 601 is vertically arranged. One end of the sliding cavity 601 communicates with the second liquid passage hole 301, and the other end of the sliding cavity 601 is connected with a socket 603. The plug 602 is slidably connected inside the sliding cavity 601. A third spring 604 is arranged inside the sliding cavity 601. The third spring 604 is used to apply an elastic force towards the socket 603 to the plug 602. Under the action of the elastic force of the spring, the plug 602 blocks the socket 603. A fourth liquid passage hole 605 is arranged on the plug 602. The male docking head 502 is of a tubular structure. One end of the male docking head 502 communicates with the third liquid passage hole 303, and the other end of the male docking head 502 can be inserted into the socket 603 and then communicate with the fourth liquid passage hole 605. When the lifting mechanism drives the upper support plate 102 to move towards the lower pressing plate 103, the tubular male docking head 502 on the lower pressing plate 103 is inserted into the socket 603 on the female docking head 501. The top end of the male docking head 502 presses the plug 602 to move into the sliding cavity 601 until the plug 602 is separated from the socket 603. At this time, the sliding cavity 601 communicates with the pipe hole of the male docking head 502 through the fourth liquid passage hole 605, so that the second liquid passage hole 301 communicates with the third liquid passage hole 303 to supply cleaning liquid to the second spray nozzle 304. When the lifting mechanism drives the upper support plate 102 to rise, the male docking head 502 is slowly pulled out of the socket 603. Under the action of the elastic force of the spring, the plug 602 moves towards one end close to the socket 603 until the plug 602 is inserted into the socket 603 to close the socket 603. At this time, the sliding cavity 601 is isolated by the plug 602, and the cleaning liquid introduced into the second liquid passage hole 301 by the liquid supply device will not leak from the sliding cavity 601.

[0044] As a preferred solution, as Figure 1 , Figure 2 and Figure 4 shown, the lifting mechanism includes a lead screw 701, a guide rod 702 and a driving block 703. The guide rod 702 is vertically arranged. The driving block 703 is slidably connected to the guide rod 702 in the vertical direction. A threaded hole is arranged on the driving block 703. The driving block 703 is threadedly connected to the lead screw 701 through the threaded hole. The lead screw 701 is rotatably connected to the bracket 101. When driving the upper support plate 102 to move in the vertical direction, by driving the lead screw 701 to rotate, the lead screw 701 drives the driving block 703 to move in the vertical direction through the threaded hole, and the driving block 703 drives the upper support plate 102 to move in the vertical direction, so as to adjust the distance between the upper support plate 102 and the lower pressing plate 103. At the same time, the guide rod 702 can guide the movement of the driving block 703, so as to guide the movement of the upper support plate 102 and ensure the smoothness of the movement of the upper support plate 102.

[0045] As a preferred solution, as Figure 1 andFigure 2 As shown, a vertical limiting chute 801 is provided on the sliding rod 107, and a limiting slider 802 is slidably connected in the limiting chute 801. The limiting slider 802 is arranged in the sliding hole. The limiting chute 801 and the limiting slider 802 are used to prevent the lower pressing plate 103 from rotating. By providing the limiting chute 801 and the limiting slider 802, it can prevent the lower pressing plate 103 from rotating when the patient's head shakes, so that when the lifting mechanism drives the upper support plate 102 to move, the male docking head 502 can accurately insert into the socket 603 of the female docking head 501, ensuring the precise docking of the male docking head 502 and the female docking head 501.

[0046] As a preferred solution, as Figure 1 and Figure 3 shown, arc-shaped positioning grooves 9 are provided on both the upper support plate 102 and the lower pressing plate 103. The arc-shaped positioning groove 9 on the upper support plate 102 is used to position the upper teeth of the patient, and the arc-shaped positioning groove 9 on the lower pressing plate 103 is used to position the lower teeth of the patient. By providing the arc-shaped positioning grooves 9 to position the upper teeth and the lower teeth of the patient, it can prevent the upper teeth of the patient from slipping off the upper support plate 102 when the lifting mechanism drives the upper support block to move, and ensure that the lower pressing plate 103 can press the lower teeth of the patient tightly.

[0047] As a preferred solution, as Figure 1 and Figure 3 shown, a silica gel pad 10 is provided in the arc-shaped positioning groove 9. By providing the silica gel pad 10, it can play a buffering role, thereby improving the comfort of the patient.
