The aperture of the guide hole 121 is larger than the outer diameter of the OCT probe. For example, the first interface 13 is provided with a first through hole 131, and the first through hole 131 is connected to the opening 113. The OCT probe 20 passes through the first through hole 131 and the opening 113 and enters the guide hole 121. The end of the OCT probe extends out of the bottom end of the guide hole 121.

The side wall of the support tube 22 is provided with a light-transmitting hole 221. The first optical fiber 23 passes through the spring tube 21 and enters the support tube 22. Optionally, the end of the first optical fiber 23 is fixed to the support tube 22 by adhesive glue, and the support tube 22 and the spring tube 21 are fixed by adhesive glue. The microlens 24 is arranged between the first optical fiber 23 and the light-transmitting hole 221, and the microlens 24 can prevent external substances from entering the first optical fiber 23 and avoid contamination of the first optical fiber 23. The light emitted by the first optical fiber 23 can pass through the microlens 24. The micro-reflector 25 is arranged on the side of the light-transmitting hole 221 away from the microlens 24, and the micro-reflector 25 can reflect the light emitted by the microlens 24 to the light-transmitting hole 221, and the light is irradiated to the inner wall of the mammary duct 200 through the light-transmitting hole 221.

[0069] The mammary duct 200 reflects the light emitted from the light transmission hole 221 to form an inspection light. The inspection light passes through the light transmission hole 221 and enters the micro-reflector 25 , and is reflected by the micro-reflector 25 to the micro-lens 24 . The inspection light transmitted by the micro-lens 24 enters the first optical fiber 23 .

[0070] One side of the rotary connector 26 is respectively connected to the spring tube 21 and the first optical fiber 23. The rotary connector 26 uses an existing optical fiber rotary connector. The spring tube 21 has a torque transmission function. The rotary connector 26 can drive the spring tube 21 and the first optical fiber 23 to rotate, and the spring tube 21 drives the support tube 22 to rotate accordingly, so as to collect more comprehensive internal images of the mammary duct 200.

[0071] The first driver 27 is used to drive the rotary connector 26 to rotate. Optionally, the first driver 27 is a motor. The first driver 27 is connected to the rotary connector 26 via a flexible belt 271 .

[0072] The second optical fiber 28 is respectively connected to the other side of the rotary connector 26 and the OCT imaging device 30. The inspection light is sequentially transmitted through the first optical fiber 23, the rotary connector 26 and the second optical fiber 28 to the OCT imaging device 30, and the OCT imaging device 30 converts the optical signal into a digital signal to display the OCT real-time image.
