Description

Technical Field

[0001] This utility model relates to the field of oral assistive device technology, specifically to a saliva suction mouth mirror for dental use. Background Technology

[0002] Gingival separators, mouth mirrors, and saliva aspirators are all medical devices used for oral examinations and treatments. Among them, mouth mirrors are used to pull the corners of the mouth and tongue, reflect to assist in examination, and obtain indirect vision during surgery. Saliva aspirators use the negative pressure generated by water flow and suction to remove saliva, intraoperative cooling fluid, debris, etc. from the mouth, improving the clarity of the surgeon's field of vision while protecting the patient's soft tissues.

[0003] In current oral treatment procedures, doctors typically need to hold the instrument in one hand and the mouth mirror in the other for traction and exploration. The saliva suction device is operated by an assistant doctor. This process is relatively cumbersome. In addition, due to the small oral cavity space, the mouth mirror and saliva suction device make the already cramped oral cavity even more crowded. The combined use of the mouth mirror and saliva suction device is not conducive to the doctor's observation of the oral cavity, which affects the treatment effect. Furthermore, the saliva suction device hanging at the corner of the patient's mouth can easily cause discomfort.

[0004] Gingival separators are used to retract and expose the gums for oral treatment and surgical procedures. When it is necessary to observe the condition of the gums during oral treatment of a patient, gingival separators are required, which requires the doctor to change handheld instruments, which is time-consuming and laborious.

[0005] Chinese Patent No. CN202321388822.2 discloses a saliva suction mouthpiece, including a mouthpiece rod, a mouthpiece lens, and a saliva suction head. The mouthpiece lens is disposed at one end of the mouthpiece rod. Both the mouthpiece lens and the mouthpiece rod are hollow and interconnected. The mouthpiece lens is provided with a plurality of saliva suction holes communicating with the interior of the mouthpiece lens, and the mouthpiece lens is also provided with a suction port communicating with the interior of the mouthpiece lens. The suction port is provided with a mating part for installing the saliva suction head. The suction port itself can be used as a saliva suction port, and can also be used as a mounting and positioning part for the saliva suction head.

[0006] The aforementioned saliva suction mouth mirror includes a suction port and a suction hole for suctioning saliva. However, since both the suction port and the suction hole are connected to the hollow inner cavity of the mouth mirror and the mouth mirror rod, the suction negative pressure inside the mouth mirror rod is diverted during suction, affecting the overall suction effect of the saliva suction mouth mirror. At the same time, when the doctor needs to observe the condition of the gums during the oral treatment of the patient, a gingival separator is required, which requires the doctor to change the handheld instrument, which is time-consuming and laborious.

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1-3 As shown, a dental suction mouth mirror includes a mouth mirror rod 1 and a mouth mirror lens 2 connected to the end of the mouth mirror rod 1; the mouth mirror lens 2 includes a mirror frame 22 and a lens 23 embedded in the surface of the mirror frame 22, a suction channel 21 is formed in the mirror frame 22, a suction channel 11 communicating with the suction channel 21 is formed in the mouth mirror rod 1, and a suction opening 3 communicating with the suction channel 21 is formed at the end of the mirror frame 22; a flap 4 is formed on the mirror frame 22, the flap 4 including a flap body 41 connected to the mirror frame 22 and a flap tip 42 formed at the end of the flap body 41; a hand grip section 12 is formed in the middle of the mouth mirror rod 1 to facilitate the gripping of the flap tip 42.

[0025] The surface of the frame 22 has a recessed structure for mounting the lens 23. Under the action of the recessed structure, the lens 23 is stably embedded in the frame 22. The suction channel 11 and the saliva suction channel 21 are connected to form an overall saliva suction channel, and both ends of the saliva suction channel are in a connected state. The suction channel 11 is connected to the air pump to realize the synchronous suction of the suction channel 11 and the saliva suction channel 21. The saliva suction port 3 is used to receive saliva in the patient's mouth and extract it through the suction channel 11 and the saliva suction channel 21.

[0026] The frame 22 is circular, and the mouth endoscope rod 1 is connected to the outer wall of the frame 22, forming an angle between the frame 22 and the mouth endoscope rod 1. Since the mouth endoscope 2 is located inside the patient's mouth during use, the circular frame 22 ensures comfort inside the patient's mouth. The mouth endoscope rod 1 moves the frame 22, thereby adjusting the position of the lens 23 under the action of the mouth endoscope rod 1. At the same time, the angle formed between the frame 22 and the mouth endoscope rod 1 meets the physician's needs for observing different positions inside the patient's mouth.

[0027] A suction channel 11 is formed in the middle of the mouth mirror rod 1 and is arranged along the length direction of the mouth mirror rod 1. A saliva suction channel 21 is formed in the middle of the mirror frame 22 and is arranged along the diameter direction of the mirror frame 22. A saliva suction port 3 is formed at the end of the saliva suction channel 21. The saliva suction channel 21, the suction channel 11 and the saliva suction port 3 are located on the same plane.

[0028] Because there is an angle between the frame 22 and the mouth mirror rod 1, the smallest gap between the suction channel 11 and the saliva suction channel 21 is located at the connection between the suction channel 11 and the saliva suction channel 21. Under the action of the saliva suction channel 21, the suction channel 11 and the saliva suction port 3 on the same plane, the overall channel is kept in a relatively straight state, which facilitates the suction of impurities when there are impurities in the patient's mouth.

[0029] The frame 22 has two opposing flaps 4, which are positioned around the suction port 3. During use, at most one flap 4 will contact the patient's gums. Under the action of the flap 4, the patient's gums will be pulled, exposing the bone tissue to the field of vision, which will facilitate the doctor's observation of the bone tissue.

[0030] The flap body 41 forms an arc-shaped structure for raising the flap tip 42. Under the action of the flap tip 42 of the raised structure, it is easy for the flap tip 42 to contact the gum while the frame 22 does not contact the gum, thus preventing interference during use.

[0031] The upward direction of the flap tip 42 is consistent with the installation direction of the lens 23, and the upward direction of the flap tip 42 is consistent with the illumination direction of the lens 23, so that the flap operation can be carried out through the flap tip 42 while illuminating through the lens 23.

[0032] The mouth mirror rod 1 includes a suction section 13 and a grip section 12 connected to each other. The suction section 13 is a circular structure formed at the end of the grip section 12. The grip section 12 has a regular polygonal cross-section and anti-slip texture 14 is formed on the surface of the grip section 12 along the length direction of the mouth mirror rod 1.

[0033] The grip section 12 with its regular polygonal structure and the anti-slip texture 14 increase the friction for the doctor's hand during use, thereby enabling precise control of the flap tip 42.

[0034] In actual use, the suction port 3 is approximately 1mm*2.4mm in size. Suction is performed when the suction port 3 is close to the gum line. The two flaps 4 are respectively positioned at approximately 20° on both sides of the suction port 3, symmetrically distributed. The flap body 41 is 3mm long and 3mm wide at the root end. The thicker root end ensures the strength of the connection point of the flap body 41, transitioning to a thinner and upward-pointing flap tip 42, facilitating flap traction operations and exposing the bone tissue to the field of vision.

[0035] The front end of the mouth mirror rod 1 is connected to the mouth mirror lens 2, and the rear end of the mouth mirror rod 1 is connected to the suction device. The narrowest part of the suction channel is the connection between the mouth mirror rod 1 and the mouth mirror lens 2, with a diameter of 1 mm. Saliva and coolant inside the oral cavity are sucked in through the suction port 3 and finally sucked away by the suction device along the channel inside the mouth mirror lens 2 and the mouth mirror rod 1.

[0036] The cross-section of the mouth mirror rod 1 transitions from a small circular cross-section to a regular hexagonal cross-section. The middle hexagonal cross-section is the part that the doctor holds when operating. The cross-section is larger than the two ends and is provided with a row of thin strip-shaped raised anti-slip textures 14, which increases friction and makes it easier for the doctor to hold.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0038] Although this document uses numerous reference numerals from the accompanying drawings—such as mouthpiece rod 1, suction channel 11, hand grip section 12, suction section 13, anti-slip texture 14, mouthpiece lens 2, saliva suction channel 21, frame 22, lens 23, saliva suction opening 3, flap 4, flap body 41, and flap tip 42—the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
