It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic structural diagram of an otoscope according to an embodiment of the present invention, and as shown in fig. 1, the otoscope according to the embodiment includes: a body 10, a detection tube 20 connected to a first end of the body 10, a camera (not shown in the figure) provided at a front end of the detection tube 20; a flushing channel 21 is provided in the probe tube. Thus, the condition in the ear of the patient can be photographed by the camera, and the ear of the patient can be cleaned by injecting the liquid into the flushing channel 21. The wash channel 21 may also be used as a surgical instrument channel. During surgery, surgical instruments may be inserted through the irrigation passage 21 and into the ear to perform the surgical procedure.

The camera can be internally provided with various photoelectric image sensors such as a CMOS image sensor, a CCD image sensor and the like according to needs. In one example, the photoelectric image sensor is a CCD image sensor with a high resolution.

As shown in fig. 2, in one embodiment, a camera is provided at the center of the cross section of the probe tube 20; the outlet of the flushing channel 21 is arranged offset from the cross-sectional center of the probe tube 20.

The front end of the detecting tube 20 is in a round table shape, the camera is positioned on the top surface, the flushing channel 21 is positioned on the side surface, and the camera and the flushing channel 21 are arranged adjacently. Therefore, the liquid flowing out of the flushing channel 21 can conveniently clean the field range shot by the camera. In addition, through the inclined ear endoscope, the flushing channel 21 is positioned above the camera, and the camera can be cleaned, so that the situation that the shot images are not clear enough due to the fact that sundries are stained on the camera is avoided.

In one embodiment, the cross-section of the irrigation channel 21 is curved, as shown in fig. 2. In other embodiments, the cross-section of the flushing channel 21 may also be a plurality of holes arranged at the side of the circular truncated cone.

The circle center of the arc of the flushing channel 21 is coincident with the circle center of the camera, and the two ends of the arc length of the arc exceed the diameter of the camera, so that the liquid flowing out of the flushing channel 21 can conveniently clean the whole camera without leaving a cleaning dead angle; compared with the mode that a plurality of holes are formed in the side face of the circular truncated cone, the water yield of the arc arrangement mode is larger, and the cleaning work is more convenient and effective.

The image detected by the camera can be displayed on the display device, and the camera is electrically connected with the display device. Referring to fig. 2, in one embodiment, a first channel 22 and a second channel 23 are provided in the probe tube 20, the first channel 22 and the second channel 23 being isolated; the camera is arranged in the first channel 22; the second channel 23 forms the flushing channel 21.

The electrical connections of the camera are provided in the first passage 22 in order to keep the first passage 22 dry, thus separating the first passage 22 from the second passage 23 by a wall.

As shown in fig. 2, in an embodiment, the first passage 22 is located at the center of the probe tube 20 and extends along the central axis of the probe tube 20; the second channel 23 is disposed off-center of the probe tube 20.

A camera is placed in the first channel 22, so that in order to avoid visual dead angles caused by the fact that the camera is far away from one side, the camera is placed in the center of the detection tube 20, namely the first channel 22 is placed in the center of the detection tube 20; the second channel 23 is separated from the first channel 22 by a wall and is therefore located off-center of the probe tube 20.

In one embodiment, the body 10 has a first cavity (not shown) communicating with the first passage 21 and a second cavity (not shown) communicating with the second passage 23; a first connecting part 11 and a second connecting part 12 are arranged on the body, the first connecting part 11 is communicated with the first cavity, and the second connecting part 12 is communicated with the second cavity; the camera is located at a position close to the front end port of the first channel 21, and an electric connection line of the camera extends to the first connection part 11 from the camera along the first channel 21 and the first cavity.

The first cavity is used to connect the first channel 21 and the first connection 11, and the second cavity is used to connect the second channel and the second connection.

The first connecting portion 11 can be used for connecting the electric connection wire of the camera in the first channel with the electric connection wire of the display device, i.e. the display device can be arranged independently, thereby reducing the volume of the ear endoscope and enabling the holding of the ear endoscope to be more stable. The second connecting portion 12 is used for injecting liquid into the flushing channel 21, and the opening area of the second connecting portion is slightly larger than the arc-shaped outlet area of the flushing channel 21, so that when the liquid enters the second channel from the second connecting portion through the second accommodating cavity, the pressure is higher, and the flushing effect of the liquid in the ear under the condition that the liquid is injected into the second connecting portion 12 with a small opening under the lower pressure is enhanced.

As shown in fig. 3, in an embodiment, the first connecting portion 11 is disposed at a connecting groove 13 at the second end of the body, and the connecting groove 13 has a through hole therein, which is communicated with the first cavity.

The connecting groove 13 is a circular groove, and the sealing of the connecting groove 13 can prevent liquid leaking out when the liquid is injected into the second connecting part from entering the first connecting part, thereby keeping the first channel communicated with the first connecting part dry; the through hole is used for the passing of the camera electric connection wire, so that the camera can be connected with the display device, and the image shot by the camera can be transmitted to the display device.

In one embodiment, the second connecting portion 12 is a pipe joint disposed at the second end of the body, the pipe joint has a hollow structure, and the hollow structure of the pipe joint is communicated with the second cavity in the body. The pipe joint is made into a hollow structure so that the injected liquid can be transferred to the second channel through the second cavity to clean the inside of the ear.

In one embodiment, an optical fiber is disposed inside the probe tube 20 and at the side of the camera, and the rear end of the optical fiber is used for connecting with the illumination unit; alternatively, an LED light source is disposed at a side portion of the camera in the detection tube 20.

The optical fiber or the LED is used for illuminating the area around the camera and providing a light source for image acquisition. The optical fiber can transmit the light generated by the illumination unit to one end of the camera for illumination, so that the illumination unit is convenient to replace, but when the light source is provided by the optical fiber, the detection tube 20 needs to have certain hardness; when the light source is provided by the LED at the side of the camera, the probe tube can be made of a softer material, but the temperature of the probe tube 20 needs to be controlled; because the probe tube 20 needs to extend into the ear, an antimicrobial material may be added to the material from which the probe tube 20 is made.

As shown in fig. 1, in one embodiment, a handle 14 is connected to a lower portion of the body 10, and a finger grip 15 is connected to an upper portion of the body 10.

Wherein, the front side of the handle 14 is provided with a finger holding part 16 for increasing the friction force between the finger and the palm, and the finger holding part 16 is concave; the finger-holding portion 15 is an annular body provided on the upper portion of the body. When the handle 14 is held, the annular body is hooked by the forefinger, so that the stability of the endoscope with the holding ear can be improved, and the definition of images shot by the camera can be further enhanced.
