Description

Technical Field

[0001] The present invention relates to the technical field of oral endoscopes with an anti-fog function, and in particular to an oral endoscope with an anti-fog function. Background Art

[0002] The existing Chinese patent publication number (CN117814735A) discloses a defogging electric heating mouth mirror device for dentists, which includes a frame housing, an installation chamber provided in the frame housing, a hand-held rod detachably connected to the outer wall of the frame housing, a sealing cover plate detachably connected to the center position at the bottom of the frame housing, an integrated circuit board and a rotating mechanism detachably connected to the sealing cover plate, an angle adjustment mechanism connected to the rotating mechanism, an electric heating mechanism movably connected to the angle adjustment mechanism, a lens provided on the electric heating mechanism, and a limit sealing mechanism detachably connected to the electric heating mechanism;

[0003] Although the heating component can prevent the lens from fogging, such a design structure still has several deficiencies. On the one hand, the structure design is complex, there are many internal parts and a large installation size is required, which is not convenient to insert into the mouths of patients with smaller oral cavities (such as children). And in cold conditions, uneven heating of the lens can cause it to crack easily. In addition, during the actual use in the dental clinic, a simple examination needs to be carried out first. If the heating lens method is used every time, it is relatively energy-consuming and the lens heating requires waiting for warming up, which will lead to an extended waiting time for the patient.

[0004] This case is proposed to solve or improve the shortcomings or deficiencies of the existing technology. Summary of the Invention

[0005] The present invention is implemented by adopting the following technical solutions:

[0006] An oral endoscope with an anti-fog function, which includes;

[0007] An endoscope outer frame, which is internally provided with a rotating component;

[0008] An endoscope lens, the back of which is fixed to the upper end of the rotating component inside the endoscope outer frame, and the endoscope lens can rotate relative to the endoscope outer frame;

[0009] An anti-fog strip, one end of the anti-fog strip is fixed on the endoscope outer frame, and the rest of the working part of the anti-fog strip is attached to the mirror surface of the endoscope lens. When the endoscope lens rotates relative to the endoscope outer frame, the endoscope lens also rotates relative to the anti-fog strip, and then absorbs or scrapes the water mist through the contact part between the anti-fog strip and the endoscope lens, so that the endoscope lens can maintain a good reflective effect for the doctor to observe the internal situation of the oral cavity through the reflection.

[0010] In a preferred embodiment, a lens rotating seat is provided inside the endoscope outer frame. The back of the endoscope lens is fixed to the top of the lens rotating seat, and the outer edge of the endoscope outer frame is higher than the lens position of the endoscope lens.

[0011] In a preferred embodiment, the endoscope outer frame is fixedly connected to the endoscope lens rod, and the endoscope lens rod is fixedly connected to the endoscope handle. The endoscope handle is for holding. The diameter of the endoscope lens rod is smaller than that of the endoscope handle, which facilitates insertion into the oral cavity and reduces the occlusion area.

[0012] In a preferred embodiment, the endoscope lens rod is a bendable and shape-setting flexible tube. The endoscope lens rod is bent at a certain angle under manual action and remains convenient for the endoscope lens to enter the oral cavity at a specific angle, facilitating the doctor's observation.

[0013] In a preferred embodiment, a torsion spring is provided between two relative rotating components of the lens rotating seat. When the endoscope lens rotates, the torsion spring is tightened and stores energy. A traction rope is wound around the rotating component of the lens rotating seat. The traction rope passes through the inside of the endoscope lens rod and bypasses the endoscope traction guide pulley rotatably arranged inside the endoscope handle and then is connected to the push plate. A controller chute is configured on the endoscope handle, and the push plate is slidably arranged within the stroke of the controller chute. As shown in the figure, when the finger pushes the push plate upward, the traction rope is pulled, so that the endoscope lens rotates. When the finger leaves the push plate, the potential energy of the torsion spring will rewind the traction rope to complete the reset.

[0014] In a preferred embodiment, the diameter of the endoscope lens is smaller than the inner diameter of the endoscope outer frame, and a water-absorbing sponge insert ring is fixedly provided at the annular gap between the endoscope outer frame and the endoscope lens. The water-absorbing sponge insert ring absorbs the water scraped by the defogging strip and wraps around the outer edge of the endoscope lens to prevent foreign objects from entering the endoscope outer frame.

[0015] In a preferred embodiment, the end of the defogging strip is provided with threads, and a threaded hole is provided on the inner wall of the endoscope outer frame. The defogging strip and the endoscope outer frame are connected by threads.

[0016] In a preferred embodiment, an endoscope auxiliary lamp is embedded at the upper end of the endoscope lens rod, and the light of the endoscope auxiliary lamp does not directly shine on the endoscope lens.

[0017] The advantages and positive effects of the present invention are:

[0018] 1. It is convenient to carry, has a simple structure, does not need to be connected to the AC power grid, can quickly perform basic examinations on patients. During the examination, by pushing the push plate with a finger, the endoscope lens can rotate relative to the defogging strip, thereby removing the water droplets condensed by the fog. Its effect can meet the needs of general oral examinations, has low energy consumption, is easy to operate, and can bend and adjust the endoscope lens rod so that the endoscope lens can be adjusted to a more convenient observation position. And after the endoscope lens rod is bent, the endoscope lens can also rotate in the same way to achieve the defogging effect. BRIEF DESCRIPTION OF THE DRAWINGS
