Technical Field

[0001] The utility model belongs to the field of oral appliances, in particular to an air bag mouth corner retractor. Background Art

[0002] Digital oral photography is an important technical means in the field of stomatology. It uses digital equipment, such as oral cameras and sensors, to take precise and clear photos of the inside of a patient's oral cavity. This technology can capture subtle oral structures and lesion details, providing an accurate basis for diagnosis. Images can be quickly acquired after shooting, saving time and improving diagnosis and treatment efficiency. It facilitates the storage, management and transmission of images, and helps to establish oral health records for patients.

[0003] When taking photos of teeth in the mouth through digital oral photography, you must use a retractor to open the mouth angle and then use a reflector. When the reflector is placed in the mouth, it will be foggy because the temperature is lower than the oral temperature, which affects the quality of the photo. Currently, most retractors are ordinary plastic retractors without anti-fog function.

[0004] With the existing oral photography retractors, after the mouth angle is pulled, due to the temperature difference between the inside and outside of the mouth, fog will appear on the reflector, and an additional defogger is still needed, such as an electric hair dryer or a defogger reflector, which requires the cooperation of additional personnel in addition to the patient. The Y-shaped plastic retractor or other shaped metal retractors can only pull the mouth angle, and it is difficult to perform defogger operations.

[0005] Therefore, those skilled in the art have proposed an airbag corner hook to solve the problems raised in the background art. Utility Model Content

The Y-shaped plastic retractor or other shaped metal retractors can only pull the mouth corner, and it is difficult to perform defog operation.

[0007] An airbag mouth corner retractor comprises a retractor body, a three-way pipe and a pressing balloon, wherein the retractor body is an integrally formed metal rod, ventilation grooves are passed through the two ends of the rod body of the retractor body, the retractor body is bent to form a "Y"-shaped structure, the two ends of the retractor body are gathered into one to form a gripping part, an expansion component is provided at the end of the retractor body, and an air outlet component is provided at the end of the expansion component;

[0008] The air outlet component comprises an arcuate portion arranged at the end of the hook body and a plurality of air outlet holes arrayed around the arcuate portion; the pressing balloon is connected to the ventilation groove through a three-way pipe.

[0009] Through the above technical solution, the mouth angle can be expanded by the expansion component, and since the hook body is in a "Y" shape structure, it is ensured that the mouth angle can be stably supported and a stable support can be maintained; by pressing the balloon, gas can be quickly ejected from the air outlet component, thereby directly drying the fog on the reflector. This method greatly improves the defogging efficiency.

[0010] Preferably, the expansion component includes an extension part connected to one end of the holding part, a support part bent from the extension part, and a connecting part connected to the support part and bent downward.

[0011] Through the above technical solution, setting the extension part can expand the mouth angle more stably; through the support part, the two sides of the mouth angle can be stably supported, so that the mouth angle can remain open during the shooting process.

[0012] Preferably, the tee includes an air inlet pipe and two groups of air outlet pipes.

[0016] Preferably, the hook body is made of stainless steel.

[0017] Preferably, the tee is made of plastic material.

[0018] Preferably, the tee is made of rubber material.

[0019] Compared with the prior art, the present utility model has the following beneficial effects:

[0020] By setting the pressing balloon and the air outlet component, pressing the balloon makes the gas eject from the air outlet hole and directly act on the fog on the reflector, greatly improving the defogging efficiency, ensuring that the taken oral photos are clear and accurate. The user can hold the holding part and press the balloon to perform the defogging operation, without complex steps and the assistance of additional personnel, saving manpower and time; the "Y" - shaped hook body structure can stably expand the mouth angle, providing good and stable shooting conditions for oral photography; integrating the functions of expanding the mouth angle and defogging into one reduces the operation tools and steps, improving the work efficiency.

[0028] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] Embodiment 1: As shown in the attached Figure 1 To Attachment Figure 5 As shown: the utility model provides an airbag mouth corner retractor, comprising a retractor body 1, a three-way pipe 2 and a pressing balloon 3, the retractor body 1 is an integrally formed metal rod, and ventilation grooves 101a are passed through the two ends of the rod body of the retractor body 1, the retractor body 1 is bent to form a "Y"-shaped structure, and the two ends of the retractor body 1 are gathered into one to form a gripping portion 101, and the gripping portion 101 is formed by bending a metal rod, and the two rods are easy to hold, and an expansion component is provided at the end of the retractor body 1, and the mouth corner can be supported by the expansion component, and because the retractor body 1 is a "Y"-shaped structure, it is guaranteed that the mouth corner can be stably supported and maintained stably, and an air outlet component is provided at the end of the expansion component;

[0030] The air outlet component includes an arched portion 105 arranged at the end of the hook body 1 and a plurality of air outlet holes 106 arrayed around the arched portion 105; the pressing balloon 3 is connected to the ventilation groove 101a through the three-way pipe 2; by pressing the balloon 3, the ventilation groove 101a can be repeatedly ventilated through the three-way pipe 2 at the gripping part. Since the pressing balloon 3 is arranged below the gripping portion 101, the air is released after the airbag is pressed by holding the handle, and the air is ejected from the plurality of air outlet holes 106 around the arched portion 105. Since the arched portion 105 is located in the corner of the mouth, fog will appear on the reflective board due to the temperature difference between the inside and outside of the mouth. The gas ejected from the air outlet holes 106 can directly dry the fog on the reflective board. This method greatly improves the demisting efficiency and is easy to operate.

[0031] The three-way pipe 2 includes an intake pipe 202 and two groups of outlet pipes 201. The intake pipe 202 is connected to the pressing balloon 3, and the two groups of outlet pipes 201 are respectively connected to the two groups of holding parts 101.

[0032] A number of air outlet holes 106 are arranged in different directions. The hook body 1 is made of stainless steel, and the three-way pipe 2 is made of plastic; the hook body 1 is made of stainless steel, with good strength and corrosion resistance; the three-way pipe 2 is made of plastic to control costs while meeting functional requirements.

[0033] As can be seen from the above, the expansion part at the end of the hook body 1 spreads the oral angle, and the "Y" - shaped structure of the hook body 1 ensures stable support, keeping the oral angle in an open state during shooting. The user holds the holding part 101 formed by bending the metal rod by hand, and the pressing balloon 3 located below the holding part 101 is in an operable position; when pressing the pressing balloon 3, gas enters through the intake pipe 202 of the three-way pipe 2; the gas entering the intake pipe 202 then splits into two groups of outlet pipes 201, and these two groups of outlet pipes 201 are respectively connected to the two groups of holding parts 101; the gas flows along the outlet pipes 201 into the ventilation grooves 101a that run through both ends of the rod body of the hook body 1; finally, the gas sprays out from a number of air outlet holes 106 arranged in different directions on the periphery of the arched part 105 at the end of the hook body 1. Since the arched part 105 is located inside the oral angle, the sprayed gas can directly act on the fog generated on the reflector due to the temperature difference between the inside and outside of the oral cavity, thus achieving the effect of defogging. And because the air outlet holes 106 are arranged in different directions, the range of the jet gas can be increased, so as to stably defog the reflector.

[0034] Embodiment 2: On the basis of Embodiment 1, the three-way pipe 2 is made of rubber. The expansion part includes an extension part 102 connected to one end of the holding part 101, a support part 103 formed by bending the extension part 102, and a connecting part 104 connected to the support part 103 and bent downward.

[0035] As can be seen from the above, through the extension part 102, the two sides of the hook can be spread to a larger angle, and with the cooperation of the support part 103, it can stably support both sides of the oral angle, keeping the oral angle in an open state during shooting, which is convenient for the user to operate the hook more conveniently.
