Description

Technical Field

[0001] The utility model relates to the technical field of medical oral cavity cleaning, and particularly relates to a precise pericoronitis irrigation device for wisdom teeth. Background Art

[0002] Wisdom teeth, that is, the third molars at the innermost part of the alveolar bone in the human oral cavity. When they erupt incompletely or are impacted, part or all of the tooth crown is covered by a blind pouch; food residues and bacteria often remain in the blind pouch. Such conditions make it easy for bacteria to grow and reproduce. When the body's resistance declines, pericoronitis is extremely likely to occur. The inflammation can spread directly or through lymphatic vessels, causing infections in adjacent tissues or fascial spaces, as well as complications such as osteomyelitis of the jawbone and septicemia. Therefore, for patients with recurrent pericoronitis of impacted wisdom teeth, the best treatment is to extract the wisdom teeth as early as possible; however, in many cases, patients' impacted wisdom teeth cannot be extracted, for example: when the patient's physical condition is poor (such as having blood system diseases, after radiotherapy, during pregnancy, having bacteremia, etc.), or when the patient is taking bisphosphonates, anticoagulants, etc., or when the operation of extracting wisdom teeth is difficult (such as nerve injury of the inferior alveolar nerve may occur during the extraction process). For the above patients who cannot extract impacted wisdom teeth, in order to reduce the incidence of pericoronitis and the occurrence of complications, it is necessary to maintain good oral hygiene in real time.

[0003] The oral irrigator is a way to effectively maintain oral hygiene and treat pericoronitis of wisdom teeth. However, the existing oral irrigators still have the following problems: First, the positioning of the pericoronal blind pouch is inaccurate. Since wisdom teeth are the last teeth in the upper and lower jaws and are located at the innermost end, it is difficult for the irrigation head to reach into the blind pouch for effective irrigation when the wisdom teeth are impacted; second, the diameter of the irrigation nozzle is large, and it cannot reach deep into the pericoronal blind pouch when the patient has limited mouth opening, resulting in poor irrigation effect; third, the oral irrigator usually has a single water column, making it difficult to clean the distal mesial interproximal space of the second molar; fourth, it cannot be adjusted according to the irrigation part. Content of the Utility Model

[0004] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide a precise pericoronitis irrigation device for wisdom teeth, which can achieve precise positioning and efficient irrigation of the pericoronal area of wisdom teeth, effectively remove plaque in the wisdom tooth blind pouch, food residues retained on each tooth surface of the wisdom tooth and in the mesial interproximal space of the wisdom tooth, achieve the hygiene maintenance of impacted wisdom teeth, prevent and treat pericoronitis, and reduce the occurrence of caries in wisdom teeth and the second molar.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A precise pericoronitis irrigation device for wisdom teeth, comprising an irrigation head, a retention part and a connecting hose. Among them, the irrigation head includes a water spraying end, an infusion catheter and a connecting end. The water spraying end and the connecting end are respectively arranged at both ends of the infusion catheter, and the central axes of the water spraying end, the connecting end and the infusion catheter are collinear; the retention part is a columnar structure as a whole and its longitudinal section is an arched structure. A clamping groove is correspondingly opened in the middle of the longitudinal section of the retention part for the mandibular teeth in the oral cavity, and a through positioning hole is opened corresponding to the infusion catheter on the upper side of the clamping groove; one end of the connecting hose is communicated with the connecting end and the other end is communicated with an external water supply device.

[0007] Based on the further optimization of the above solution, an anti-rotation block is arranged on the outer wall of the end of the infusion catheter close to the water spraying end, and an anti-rotation clamping groove is opened corresponding to the anti-rotation block in the positioning hole, and the anti-rotation clamping groove is communicated with the side surface of the fixing part far away from the connecting end, so as to facilitate the clamping between the anti-rotation block and the anti-rotation clamping groove.

[0008] Based on the further optimization of the above solution, the positioning hole is an inclined structure (that is, the central axis of the positioning hole forms a certain angle with the bottom plane of the fixing part), and the positioning hole is inclined from the connecting end to the water spraying end (that is, the height of the end of the positioning hole close to the connecting end is greater than the height of the end of the positioning hole close to the water spraying end).

[0009] Based on the further optimization of the above solution, a plurality of installation holes are opened at the end of the water spraying end for installing nozzles in different directions and with different lengths (such as nozzles in the blind pocket, nozzles in the mesial adjacent space of wisdom teeth, etc.).

[0010] Based on the further optimization of the above solution, the inner diameter of the infusion catheter is φ1.8mm - φ2.2mm, and the outer diameter is φ3.2mm - φ3.8mm.

[0011] Based on the further optimization of the above solution, the length of the retention part is 20mm - 25mm, and the angle between the central axis of the positioning hole and the bottom plane of the retention part is 1° - 20°; the length of the infusion catheter is greater than the length of the positioning hole, so as to ensure that both ends of the infusion catheter are exposed on both side surfaces of the retention part.

[0012] Based on the further optimization of the above solution, the length of the anti-rotation block is 6.5mm - 7.5mm, the height is 0.8mm - 1.2mm, and the thickness is 0.3mm - 0.8mm.

[0013] Based on the further optimization of the above solution, the length of the connecting hose is 60mm - 600mm, the inner diameter of the connecting hose is φ2.3mm - φ2.7mm and the inner diameter of the connecting hose is greater than the inner diameter of the infusion catheter, and the outer diameter of the connecting hose is φ3.4mm - φ4.0mm and the outer diameter of the connecting hose is greater than the outer diameter of the infusion catheter.

[0014] The following are the technical effects of the method of the present utility model:

[0015] Through the arrangement of the fixing part, the whole flushing device can be effectively clamped on the lower jaw teeth (such as the lower molar teeth) in the oral cavity, and the accurate and stable positioning of the flushing nozzle can be realized by gently biting the end face of the retention part with the upper teeth, effectively avoiding problems such as that it is difficult for the flushing head to extend into the blind pocket when the wisdom tooth is impacted, or the nozzle deviation caused by the flushing force and the shaking of the user's hand during the flushing process; at the same time, this method does not require the user to open the mouth too wide, ensuring the comfort of the user during the tooth flushing process. The flushing head composed of the water spraying end, the infusion catheter and the connecting end can, firstly, install nozzles with multiple directions and lengths, so that the flushing liquid is sprayed in multiple directions, and personalized and all-round targeted flushing is carried out on the pericoronal blind pocket, each tooth surface of the wisdom tooth and the mesial adjacent space of the wisdom tooth, thoroughly removing bacteria and food residues; secondly, it does not need to be held by the user, reducing the operation difficulty, and thus forming effective flushing.

[0016] The structure of the present application is simple and the operation is convenient. It can effectively realize the precise flushing around the pericoronal of the wisdom tooth, and can be operated by the patient with one hand, so as to realize the long-term hygiene maintenance around the impacted wisdom tooth, prevent and treat pericoronitis, and reduce the patient's medical follow-up rate.
