Detailed Description
In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.
As shown in fig. 1 to 6, an intervertebral foramen mirror for preventing overflow of a tail end provided in an embodiment of the present invention includes a main body 1, a video interface 2, a light source interface 3, a water inlet interface 4, a water outlet interface 5, an instrument interface 6 and a working mirror tube 7 disposed at one end of the main body 1, wherein one end of the working mirror tube 7 away from the main body 1 is an inclined plane, a working channel 8 communicated with the instrument interface 6, a water inlet channel 9 communicated with the water inlet interface 4, a water outlet channel 10, and a light source channel 11 connected with the light source interface 3 are disposed in the working mirror tube 7, and a camera 12 connected with the video interface 2 is mounted at one end of the light source channel 11;
the light source channel is internally provided with the optical fiber to transmit the light source, so that the visual field is clear, the camera 12 cannot completely block the light source channel 11, and a part of the optical fiber extends out from the periphery of the camera 12, so that a good operation visual field is provided for a doctor;
a first channel 13 and a second channel 14 are arranged in the main body 1, one end of each of the first channel 13 and the second channel 14 is communicated with the water outlet port 5, the other end of the first channel 13 is communicated with the working channel 8, and the other end of the second channel 14 is communicated with the water outlet channel 10;
