[0002] An otoscope is an endoscope used to examine the eardrum, tympanic cavity (when the eardrum is perforated), diagnose diseases of the middle ear and external auditory canal, and perform surgical imaging of the middle ear and lateral skull base. An otoscope can observe areas that are difficult to observe with a surgical microscope, such as the upper tympanic cavity and the posterior tympanic cavity, so as to detect middle ear lesions in a timely manner and reduce the recurrence rate of lesions. Generally, an otoscope consists of an optical imaging system and a lighting system. When used in conjunction with a camera system and a cold light source, medical staff can observe the patient's ear lesions through a high-definition display.

[0003] The existing technology has the following problems: Since the surgeon holds the scope with one hand and operates with the other hand, in order to stop bleeding and keep the surgical field clear, the operation needs to be interrupted to stop bleeding, which is time-consuming and laborious. In order to remove some bones during the operation, an assistant is required to continuously flush and suction, which makes it difficult to ensure the consistency of flushing direction and field of view, and also reduces the efficiency of the operation.

[0004] In summary, how to improve surgical efficiency is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a sustainable underwater otoscope, which can be used to perform surgery without interrupting the operation to stop bleeding, and can continuously flush bones and bleeding in the ear.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The core of the present invention is to provide a sustainable underwater otoscope, which can be used to perform surgery without interrupting the operation to stop bleeding, and can continuously flush bones and bleeding in the ear.

[0029] Please refer to Figures 1 to 6 , Figure 1 A cross-sectional view of the sustainable underwater operable otoscope provided by the present invention; Figure 2 This is an external structural diagram of the sustainable underwater operation otoscope provided by the present invention; Figure 3 Schematic diagram of a sustainable underwater operated otoscope using the first water injection tube; Figure 4 Schematic diagram of a sustainable underwater operated otoscope using a second water injection tube; Figure 5 A cross-sectional view of a second water injection pipe provided by the present invention; Figure 6 This is a schematic diagram of the connecting piece provided by the present invention.

[0030] A sustainable underwater operable ear endoscope comprises: a shell, an imaging device for inserting into the ear and taking pictures, a lighting system for providing lighting to the shooting area of ​​the imaging device, and a cleaning system for inserting into the ear to clean the shooting area. The cleaning system, the imaging device, and the lighting system are all arranged on the shell, the cleaning system is arranged on the imaging device so that the cleaning system and the imaging device can be inserted into the ear at the same time, and the lighting system is connected to the imaging device.

[0031] It should be noted that the shell can be set to any structure. The shell does not need to be inserted into the ear, so the shell can be set to a shape that is easy to hold. The shell is used to install the cleaning system, imaging device and lighting system. Since the imaging device needs to be inserted into the ear, the imaging device includes an imaging instrument for inserting into the ear, such as an imaging tube and other slender devices, and an external display instrument for observing the captured image. The cleaning system needs to clean the shooting area of ​​the imaging device, so in order to reduce the overall volume of the cleaning system and the imaging device, the cleaning system and the imaging device are installed together to reduce the occupied space. The cleaning system includes a cleaning pipeline, and the water outlet 12 of the pipeline is close to the front end of the imaging device for shooting. The shooting area of ​​the imaging device can be set according to the actual application situation and is not particularly limited.

[0032] The lighting system is used to provide illumination. In order to reduce the occupied space, the light source provided by the lighting system can be transmitted along the imaging device and emitted from the front end of the imaging device to illuminate the area photographed by the imaging device. In this way, the imaging device can be inserted into the ear alone.

[0033] Under the action of external force, the shell drives the imaging device and the cleaning system into the ear. The imaging device can capture the situation inside the ear and generate images to check the situation inside the ear. Since there is no light inside the ear, a lighting system is needed to provide lighting to the area captured by the imaging device so that the image is displayed clearly. During surgery, since the cleaning system is arranged on the imaging device, and the cleaning system and the imaging device are inserted into the ear at the same time, when the area captured by the imaging device is bleeding or bone needs to be cleaned, an external water source can be used to connect the cleaning system to continuously irrigate and circulate the area captured by the imaging device, so that the field of view can always be kept clear, no other auxiliary devices are required, and there is no need to interrupt the surgical operation, thereby improving the efficiency of the operation.
