The present application claims priority to Chinese patent application No. 201920213173X filed on Feb. 19, 2019, entitled “Oral Treatment Guide Plate,” which is hereby incorporated by reference in its entirety.
The present application relates to the technical field of oral treatment equipment, and in particular to an oral treatment guide plate.
With the promotion of oral treatment technology and the improvement of people's requirements for oral health, more and more patients choose to implant and restore missing teeth or have root canal treatment for affected teeth. Oral treatment surgery is a precise operation performed in a small space. During dental implants or root canal treatment, the position and angle of surgical instruments are key goals for the success of the operation, and the oral treatment guide plate technology is a powerful tool to achieve this goal. The oral treatment guide plate may assist a dentist in performing the surgical procedure precisely according to the predetermined surgical position. When the oral treatment guide plate is used, it is necessary to use therewith a suction device and a saliva suction tube to suck away blood, saliva or washing fluid in the patient's oral cavity in time to prevent them from entering the esophagus or respiratory tract, causing patient discomfort, and at the same time to make the operation field of view clear and reduce pollution.
At present, the traditional saliva suction tube is generally a disposable long straw made by plastic. When in use, the suction device is connected to the saliva suction tube by a hose, and then the saliva suction tube is inserted into the patient's oral cavity to manually suck fluid in the tongue and buccal areas separately. Therefore, it is impossible for a dentist to perform oral treatment operation and saliva suction operation simultaneously, and the assistance of other medical staff is often required, which not only wastes human resources, but also takes up surgical operation space in the oral cavity. In addition, due to the presence of fluid in the tongue and buccal areas, it is inconvenient to switch back and forth between the tongue and buccal areas when sucking saliva. Moreover, when using a saliva suction tube, the suction tip sticks to the mucosal flap for a long time, resulting in tissue edema.
Embodiments of the present application provide an oral treatment guide plate, so as to solve the problems of single function, inconvenience in saliva suction and poor suction effect of the existing oral treatment guide plates.
An embodiment of the present application provides an oral treatment guide plate, including a guide plate body, a saliva suction main tube and a plurality of saliva suction branch tubes; a notch is formed on the guide plate body, and the saliva suction branch tubes are arranged on both sides of the notch; outlets of the plurality of saliva suction branch tubes are connected to an inlet of the saliva suction main tube, and an outlet of the saliva suction main tube is configured to connect with a suction device.
In an embodiment, the saliva suction branch tubes comprise a lingual saliva suction tube and a buccal saliva suction tube, the lingual saliva suction tube is adhered to a side surface of the guide plate body toward the tongue, and the buccal saliva suction tube is adhered to a side surface of the guide plate body toward the buccal mucosa.
In an embodiment, the lingual saliva suction tube is provided with a plurality of first suction holes on a side toward the tongue, and the buccal saliva suction tube is provided with a plurality of second suction holes on a side toward the buccal mucosa.
In an embodiment, the first suction holes are discretely distributed on the lingual saliva suction tube, and the second suction holes are discretely distributed on the buccal saliva suction tube.
In an embodiment, the outlet of the saliva suction main tube is provided with a tapered tube joint.
In an embodiment, the saliva suction branch tube is a flat-shaped tube attached to a surface of the guide plate body.
In an embodiment, the guide plate body, the saliva suction main tube and the saliva suction branch tubes are all integrally connected.
The oral treatment guide plate according to the embodiments of the present application includes a guide plate body, a saliva suction main tube and a plurality of saliva suction branch tubes. Through the notch formed on the guide plate body, the position and angle of the surgical instruments for oral treatment may be determined and guided, and both the convenience and accuracy of the operation may be improved; through the saliva suction tubes arranged on both sides of the notch, the fluid in the patient's oral cavity may be sucked in time during the operation. The outlets of the plurality of saliva suction branch tubes are all connected to the inlet of the saliva suction main tube, and the outlet of the saliva suction main tube is configured to connect with a suction device. The suction device is used to form a negative pressure in the lumina of the saliva suction main tube and the saliva suction branch tubes, so that the fluid in the patient's oral cavity enters the saliva suction branch tubes from the inlets of the saliva suction branch tubes, and then enters the saliva suction main tube from the outlets of the saliva suction branch tubes, and then the fluid through multi-path is merged and discharged out of the oral cavity. Saliva, blood and cleaning fluid produced during the operation may be discharged in time by providing saliva suction branch tubes on both sides of the notch, which improves the effect and efficiency of saliva suction and prevents pollution caused by fluid entering the treatment site. Moreover, the saliva suction branch tubes do not occupy the surgical operation space, avoiding the impact on the operation field of view. The oral treatment guide plate has functions of both guiding an oral treatment and sucking saliva, facilitating a dentist to complete oral treatment surgery independently, thereby saving labor and time.

A notch 11 is formed on the guide plate body 1 corresponding to the missing (or affected) tooth area of the patient. The notch 11 may be provided with an aperture or fitted with a sleeve to facilitate determining and guiding the position and angle of the surgical instrument. Oral surgery applicable to the oral treatment guide plate includes dental implant surgery, root canal treatment surgery, tooth extraction surgery, and other treatment operations that require saliva suction.
Both sides of the notch 11, namely the lingual side and the buccal side, are provided with saliva suction branch tubes. Each saliva suction branch tube has a hollow interior for liquid flow-through. The saliva suction branch tube includes an inlet and an outlet, wherein the inlet of the saliva suction branch tube is configured to suck fluid in the patient's oral cavity, and the outlets of the plurality of saliva suction branch tubes are all connected to the inlet of the saliva suction main tube 2. The outlet of the saliva suction main tube 2 is configured to connect with a suction device (not shown in the FIGURE). The suction device may adopt a suction pump to generate negative pressure. The respective streams of fluid in the plurality of saliva suction tubes converge in the saliva suction main tube 2, and are uniformly discharged from the oral cavity through the outlet of the saliva suction main tube 2.
The oral treatment guide plate according to this embodiment includes a guide plate body, a saliva suction main tube and a plurality of saliva suction branch tubes. Through the notch formed on the guide plate body, the position and angle of the surgical instruments for oral treatment may be determined and guided, and both the convenience and accuracy of the operation may be improved; through the saliva suction branch tubes arranged on both sides of the notch, the fluid in the patient's oral cavity may be sucked in time during the operation. The outlets of the plurality of saliva suction branch tubes are all connected to the inlet of the saliva suction main tube, and the outlet of the saliva suction main tube is configured to connect with a suction device. The suction device is used to create negative pressure in the lumina of the saliva suction main tube and the saliva suction branch tubes, so that the fluid in the patient's oral cavity enters the saliva suction branch tubes from the inlets thereof, and then enters the saliva suction main tube from the outlets of the saliva suction branch tubes, and then the fluid through multi-path is merged and discharged out of the oral cavity. Saliva, blood and cleaning fluid produced during the operation may be discharged in time by providing saliva suction branch tubes on both sides of the notch, which improves the effect and efficiency of saliva suction and prevents pollution caused by fluid entering the treatment site. Moreover, the saliva suction branch tubes do not occupy the surgical operation space, avoiding the impact on the operation field of view. The oral treatment guide plate has functions of both guiding an oral treatment and sucking saliva, facilitating a dentist to complete oral treatment surgery independently, thereby saving labor and time.
Further, as shown in
When the number of notches 11 is one, namely a single missing (or affected) tooth is present in the patient's oral cavity, or multiple consecutive missing (or affected) teeth that form a missing (or affected) teeth area are present in the oral cavity, and when the notch 11 is located on the right or left side of the guide plate body 1, one lingual saliva suction tube 3 and one buccal saliva suction tube 4 are provided.
When the number of notches 11 is two or more, namely multiple missing (or affected) teeth are present in the oral cavity of the patient to form multiple missing (or affected) teeth areas, and when the multiple notches 11 are all located on the right or left side of the guide plate body 1, one lingual saliva suction tube 3 and one buccal saliva suction tube 4 are provided. Wherein the lingual saliva suction tube 3 and the buccal saliva suction tube 4 both extend along the surface of the guide plate body 1 to the most distal notch 11, and corresponding to each notch 11, an inlet configured to suck fluid is provided.
When the number of notches 11 is two or more, and some of the multiple notches 11 are located on the right side of the guide plate body 1, and the others are located on the left side of the guide plate body 1, two lingual saliva suction tubes 3 and two buccal saliva suction tubes 4 are provided, that is, one lingual saliva suction tube 3 and one buccal saliva suction tube 4 are provided on the left side of the guide plate body 1, while one lingual saliva suction tube 3 and one buccal saliva suction tube 4 are also provided on the right side of the guide plate body 1.
Still further, the lingual saliva suction tube 3 is provided with a plurality of first suction holes 31 on a side toward the tongue, and the buccal saliva suction tube 4 is provided with a plurality of second suction holes 41 on a side toward the buccal mucosa. The effect and efficiency of saliva suction are improved by providing the plurality of first suction holes 31 toward the lingual side and the plurality of second suction holes 41 toward the buccal side.
Still further, the first suction holes 31 are discretely distributed on the lingual saliva suction tube 3, and the second suction holes 41 are discretely distributed on the buccal saliva suction tube 4. Through the discretely distributed first suction holes and second suction holes, the problem of tissue edema caused by the existing saliva suction tube being adsorbed on the gum mucosa for a long time is avoided.
Further, as shown in
Further, the saliva suction branch tube is a flat-shaped tube attached to a surface of the guide plate body 1. The flat-shaped saliva suction branch tube can better adhere to the surface of the guide plate body 1, so that the overall streamline of the oral treatment guide plate is ensured and the patient's foreign body sensation is reduced.
Further, the guide plate body 1, the saliva suction main tube 2 and the saliva suction branch tubes are all integrally connected. Specifically, the guide plate body 1, the saliva suction main tube 2, and the saliva suction branch tubes may be integrally printed and formed by 3D printing. Integration of the saliva suction structure on the guide plate body 1 makes the saliva suction process more efficient and safe, and the surgical operation space more compact to broaden the operation field of view.
Still further, manufacturing methods of the oral treatment guide plate include a model method and a computer aided design/computer aided manufacture method (CAD/CAM method). Wherein, the model method refers to a method of making an oral treatment guide plate on a model after obtaining the physical model of the patient's oral cavity by modeling; the CAD/CAM method refers to a method of designing on a three-dimensional reconstruction virtual model based on the patient's CT data and processing the oral treatment guide plate through a computer aided production technology. In this embodiment, the CAD/CAM method is taken as an example for illustration. A three-dimensional model is generated in the computer aided design software based on the CT data of the patient's oral cavity, and then the structure of the saliva suction main tube 2 and the saliva suction branch tubes are designed on the surface of the model, and finally an oral treatment guide plate with a saliva suction structure is made by 3D printing.
The following will be specifically described in conjunction with the method of using the oral treatment guide plate in this embodiment.
When performing an oral treatment operation, the guide plate body 1 was first fixed onto the patient's tooth surface, and the surgical instrument was operated at the notch 11. During the operation, blood was produced at the notch 11, and saliva was secreted in the patient's oral cavity at the same time. Then, the negative pressure suction device was turned on, and negative pressure was formed in the lumina of the saliva suction main tube 2, the lingual saliva suction tube 3, and the buccal saliva suction tube 4. The lingual fluid in the oral cavity of the patient entered the saliva suction main tube 2 via the lingual saliva suction tube 3 through the first suction holes 31, the buccal fluid in the patient's oral cavity entered the saliva suction main tube 2 via the buccal saliva suction tube 4 through the second suction holes 41, and the saliva suction main tube 2 discharged the merged fluid out of the oral cavity via the tube joint 21.
It can be seen from the above-mentioned embodiments that the oral treatment guide plate according to the present application includes a guide plate body, a saliva suction main tube and a plurality of saliva suction branch tubes. Through the notch formed on the guide plate body, the position and angle of the surgical instruments for oral treatment may be determined and guided, and both the convenience and accuracy of the operation can be improved; through the saliva suction branch tubes arranged on both sides of the notch, the fluid in the patient's oral cavity may be sucked in time during the operation. The outlets of the plurality of saliva suction branch tubes are all connected to the inlet of the saliva suction main tube, and the outlet of the saliva suction main tube is configured to connect with a suction device. The suction device is used to generate negative pressure in the lumina of the saliva suction main tube and the saliva suction branch tubes, so that the fluid in the patient's oral cavity enters the saliva suction branch tubes from the inlets thereof, and then enters the saliva suction main tube from the outlets of the saliva suction branch tubes, and then the fluids through multi-path is merged and discharged out of the oral cavity. Saliva, blood and cleaning fluid produced during the operation may be discharged in time by providing saliva suction branch tubes on both sides of the notch, which improves the effect and efficiency of saliva suction and prevents pollution caused by fluid entering the treatment site. Moreover, the saliva suction branch tubes do not occupy the surgical operation space, avoiding the impact on the operation field of view. The oral treatment guide plate has functions of both guiding an oral treatment and sucking saliva, facilitating a dentist to complete oral treatment surgery independently, thereby saving labor and time.
Finally, it should be noted that the embodiments above are only for illustrating the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions documented in the preceding embodiments may still be modified, or parts of the technical features thereof may be equivalently substituted; and such modifications or substitutions do not depart the essence of the corresponding technical solutions from the scope of the technical solutions of various embodiments of the present application.
