[0048] The following is a clear and complete description of the technical solution of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this application.

[0049] like Figure 1 As shown, an embodiment of the present application provides a breast sheath tube 10, which includes a gripping column 11, a tube body 12, a first interface 13, and a second interface 14. The breast sheath tube 10 can be inserted into the mammary duct to provide guidance for an OCT probe, thereby applying OCT (Optical Coherence Tomography) technology to examine the interior of the mammary duct. Optionally, the breast sheath tube 10 is made of metal.

[0050] like Figure 2 As shown, the gripping column 11 includes a first end 11a and a second end 11b opposite each other. Optionally, the gripping column 11 is in the shape of a stepped shaft, including a large diameter portion 111 and a small diameter portion 112 connected to each other, with the first end 11a located in the small diameter portion 112 and the second end 11b located in the large diameter portion 111. The end surface of the first end 11a is provided with an opening 113, which extends along the axis of the gripping column 11 and is open at one end. The diameters of the large diameter portion 111 and the small diameter portion 112 are set as required. For example, the diameter of the large diameter portion 111 is 30 mm, and the diameter of the small diameter portion 112 is 20 mm.

[0051] The tube body 12 is disposed at the first end 11a of the gripping column 11. Optionally, the axis of the tube body 12 is collinear with the axis of the gripping column 11. The tube body 12 is provided with a guide hole 121, which is a through hole extending along the axis of the tube body 12. The guide hole 121 is connected to the opening 113.

[0052] like Figure 3As shown, the tubular body 12 is optionally detachably connected to the gripping column 11. A boss 114 is provided at the first end 11a of the gripping column 11. The sidewall of the boss 114 is provided with external threads. The end of the tubular body 12 is provided with internal threads that mate with the external threads of the boss 114, thereby achieving detachable connection between the tubular body 12 and the gripping column 11. If desired, the tubular body 12 and the gripping column 11 can also be integrally formed.

[0053] like Figure 4 and Figure 5 As shown, the first interface 13 is provided at the second end 11b of the holding column 11. The first interface 13 is connected to the guide hole 121 of the tube body 12. The first interface 13 can guide the OCT probe 20 into the guide hole 121. 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 tube body 12 is inserted into the mammary duct, and the OCT probe can examine the inside of the mammary duct.

[0054] The second interface 14 is provided at the second end 11b of the holding column 11, and the second interface 14 is connected to the guide hole 121 of the tube body 12, and is used to inject fluid into the guide hole 121. Optionally, the fluid is a liquid or a gas, for example, the fluid is a cleaning fluid. The second interface 14 is provided with a second through hole 141, and the second through hole 141 is connected to the opening 113. The fluid injected by the second interface 14 enters the mammary duct through the second through hole 141, the opening 113 and the guide hole 121 to clean the inside of the mammary duct, which is beneficial for the OCT probe 20 to obtain clear inspection images. When the OCT probe is located in the guide hole 121, the fluid flows in the gap between the OCT probe and the guide hole 121.

[0055] Optionally, the delivery device is connected to the second interface 14 via a connecting tube 41 , and the delivery device can deliver fluid to the second interface 14 . The connecting tube 41 is a flexible tube.

[0056] The mammary sheath tube 10 of this embodiment provides a passage for the OCT probe to enter the mammary duct, enabling OCT technology to be applied to the internal examination of mammary ducts. During use, the OCT probe 20 is inserted into the tube body 12 through the first interface 13. The connecting tube 41 is connected to the second interface 14. The tube body 12 is then inserted into the mammary duct along the pathological ostium. The end of the OCT probe 20 extends out of the tube body 12 to examine the mammary duct. To flush the mammary duct, the delivery device is activated to inject a cleaning fluid into the duct.

[0057] In some embodiments, the breast sheath 10 further includes a third interface 15, which is disposed at the second end 11b of the gripping column 11 and communicates with the guide hole 121 of the tube body 12. For example, the third interface 15 is provided with a third through hole 151, which communicates with the opening 113 to connect the third through hole 151 with the guide hole 121. The third interface 15 is used to connect to an invasive device, such as a puncture device or a surgical sampling device such as an ablation / basket.

[0058] The lesion position in the mammary duct is detected by the OCT probe, and the lesion position is located through the mammary sheath 10. The invasive device is connected to the third interface 15, and the invasive device passes through the tube body 12 to perform an invasive operation on the lesion position.

[0059] Optionally, when performing an invasive operation, it is determined as needed whether to remove the OCT probe from the breast sheath 10. For example, if there is enough space for the invasive operation, it is not necessary to remove the OCT probe from the breast sheath 10.

[0060] like Figure 3 As shown, in some embodiments, the length L of the tube body 12 is 5 to 15 cm, and the inner diameter D of the tube body 12 is 0.2 to 2 mm. The tube body 12 can be manufactured into various models to meet the needs of different patients.

[0061] In some embodiments, a scale (not shown) is provided on the outer wall of the tube body 12. The scale is used to remind the operator of the depth to which the tube body 12 enters the mammary duct.

[0062] like Figure 6 As shown, an embodiment of the present application provides a breast duct inspection device 100 , which includes the breast sheath 10 , the OCT probe 20 , the OCT imaging device 30 , and the delivery device 40 as described above.

[0063] The OCT probe 20 can pass through the first interface 13 of the breast sheath 10 and enter the guide hole 121 of the tube body 12. For example, the OCT probe 20 is detachably connected to the first interface 13, and the inspection end 20a of the OCT probe 20 passes through the first through hole 131, the opening 11, and the guide hole 121, and extends out of the guide hole 121.

[0064] The OCT imaging device 30 is connected to the OCT probe 20 and is used to display images acquired by the OCT probe 20. The OCT imaging device 30 can utilize an existing OCT imaging device. The OCT imaging device 30 converts the optical signals acquired by the OCT probe 20 into digital signals to display real-time OCT images, facilitating accurate diagnosis of breast diseases. Optionally, the OCT imaging device 30 also has the function of storing and analyzing examination images.

[0065] The delivery device 40 is connected to the second port 14 of the mammary sheath 10. For example, the delivery device 40 is connected to the second port 14 via a connecting tube 41. The delivery device 40 can inject fluid into the second port 14, and the mammary sheath 10 guides the fluid into the mammary ducts to clean the mammary ducts and obtain clearer examination images. Optionally, the delivery device 40 is a delivery pump.

[0066] When using the mammary duct inspection device 100 of this embodiment, the OCT probe 20 and delivery device 40 are connected to the mammary sheath 10, and the OCT probe 20 is connected to the OCT imaging device 30. The tube 12 passes through the diseased nipple and enters the mammary duct. The OCT probe 20 acquires a three-dimensional structural image of the interior of the mammary duct, and the OCT imaging device 30 displays the acquired image in real time.

[0067] like Figure 7 As shown, in some embodiments, the OCT probe 20 includes: a spring tube 21, a support tube 22, a first optical fiber 23, a microlens 24, a micromirror 25, a rotary connector 26, a first driver 27 and a second optical fiber 28. Figure 7 The arrow in the middle is the direction of light propagation.

[0068] The support tube 22 is connected to one end of the spring tube 21. Optionally, the support tube 22 is a metal hard tube that is not easily deformed. 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, and the support tube 22 is fixed to the spring tube 21 by adhesive. The microlens 24 is arranged between the first optical fiber 23 and the light-transmitting hole 221. The microlens 24 can prevent foreign matter from entering the first optical fiber 23 and avoiding contamination of the first optical fiber 23. The light emitted by the first optical fiber 23 can pass through the microlens 24. The microreflector 25 is arranged on the side of the light-transmitting hole 221 away from the microlens 24. The microreflector 25 can reflect the light emitted by the microlens 24 to the light-transmitting hole 221, and the light is irradiated onto 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 . The micro-reflector 25 reflects the inspection light 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 connects the spring tube 21 and the first optical fiber 23. Rotary connector 26 uses an existing optical fiber rotary connector. The spring tube 21 transmits torque, driving the spring tube 21 and the first optical fiber 23 to rotate. The spring tube 21 then drives the support tube 22 to rotate, allowing for more comprehensive internal image capture 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, and the first driver 27 is connected to the rotary connector 26 via a flexible belt 271 .

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

[0073] like Figure 8 As shown, in some embodiments, the OCT probe 20 further includes a translation mechanism 29. The translation mechanism 29 connects the rotary connector 26 and the first driver 27. The translation mechanism 29 can drive the rotary connector 26 to translate, thereby driving the inspection end 20a of the OCT probe 20 to translate, so as to better obtain a three-dimensional structural image of the interior of the mammary duct.

[0074] In some embodiments, the translation mechanism 29 includes a base 291 , a bracket 292 , a second driver 293 and a screw rod 294 .

[0075] Bracket 292 is slidably mounted on base 291. For example, base 291 is provided with a guide rail 295, and bracket 292 is slidably mounted on guide rail 295. Rotary connector 26 and first actuator 27 are both mounted on bracket 292. Bracket 292 can drive translation of rotary connector 26 and first actuator 27. Bracket 292 is provided with a threaded hole.

[0076] A second driver 293 is mounted on the base 291. Optionally, the second driver 293 is a motor. A screw 294 is connected to the output end of the second driver 293 and fits into a threaded hole in the bracket 292. Rotation of the screw 294 drives the bracket 292 to translate along the guide rail 295. Optionally, both the first driver 27 and the second driver 293 are controlled using existing control methods.

[0077] like Figure 9 As shown, the support tube 22 includes a thick-walled portion 222 and a thin-walled portion 223 connected to each other. The end of the thin-walled portion 223 is connected to one end of the thick-walled portion 222. The microlens 24 and micromirror 25 are both mounted on the thin-walled portion 223. The wall thickness of the thin-walled portion 223 is smaller than that of the thick-walled portion 222, and the aperture of the thin-walled portion 223 is larger than that of the thick-walled portion 222, facilitating the installation of the microlens 24 and micromirror 25.

[0078] In some embodiments, the mammary duct inspection device 100 further includes an invasive device (not shown), which can pass through the third port 15 of the mammary sheath 10 and enter the guide hole 121 of the tube body 12. When the third port 15 is not in use, the third through hole 151 of the third port 15 is sealed with a sealing plug to reduce the possibility of contamination of the third port 15.

[0079] Optionally, the invasive device includes at least one of a puncture device, an ablation device, a laser generator, and a surgical device. The mammary duct inspection device 100 of this embodiment applies OCT technology to inspect the interior of mammary ducts and can locate the location of lesions through the mammary sheath. Based on this location, corresponding positioning, sampling, or treatment is performed, thereby enhancing the diagnostic efficiency of mammary duct lesions, improving the accuracy of mammary duct inspection, and making treatment more minimally invasive.

[0080] The embodiments of the present application are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application.
