Description

Technical Field

[0001] The utility model belongs to the technical field of breast ductoscope assistance, in particular to an auxiliary device for breast ductoscope inspection. Background Art

[0002] Nipple discharge is a common symptom of breast disease and can be divided into physiological and pathological discharge. Most pathological nipple discharges are early manifestations of intraductal lesions, usually indicating benign or malignant breast diseases, and require further examination to identify the cause. Ductoscopy, also known as electronic breast microendoscope, can visually display the situation inside the milk duct and can identify lesions as small as 0.01mm in diameter in the duct. It is the preferred method for diagnosing the cause of nipple discharge and an auxiliary treatment tool for some intraductal lesions. It can also provide a reliable basis for the early diagnosis of breast cancer.

[0003] Clinically, the procedure for ductoscopy is generally to first disinfect the affected breast, gently squeeze the nipple and areola, find the discharge duct, inject local anesthetic into the duct, then use No. 5 to 10 lacrimal probes to insert the diseased duct in turn to dilate it, and finally insert the ductoscope into the duct to check the cause of nipple discharge under the guidance of the ductoscope.

[0004] During the dilation process, it is necessary to replace the lacrimal duct probes with different diameters many times, which is cumbersome. In addition, the nipple conditions of patients are different. During the above operation, it is easy for the replaced probes to be inserted into different ducts. Even the target duct may be lost during the operation. Utility Model Content

The milk duct is dilated for the second time through the sheath tube 3. After the dilation is completed, the sheath tube 3 stays in the milk duct to provide a channel for the insertion of the milk ductoscope, avoid the milk duct from retracting after dilation, and ensure that the milk ductoscope is smoothly inserted into the milk duct.

[0024] A fixing plate 10 is fixed to the right end of the sheath tube 3. A through hole communicating with the left and right sides is opened in the fixing plate 10. The right end of the sheath tube 3 is inserted into the through hole.

[0025] A protective sleeve 5 is fixed on the left side wall of the fixing plate 10. The protective sleeve 5 is a tubular structure. The right end of the protective sleeve 5 is fixed on the left side wall of the fixing plate 10. The protective sleeve 5 is made of medical silicone material. The medical silicone has little stimulation to the skin and is ductile. The protective sleeve 5 is sleeved on the outside of the nipple. When the sheath tube 3 fixing plate 10 is fixed to the nipple, the sheath tube 3 is fixed in the milk duct. This paragraph of text as a whole constitutes a fixing component for fixing the fixing plate 10 on the nipple. When the fixing component is used, after the sheath tube 3 is inserted into the milk duct, the fixing plate 10 moves to the nipple. At the head end, the doctor uses his fingers to open the left end of the protective sleeve 5, puts the protective sleeve 5 on the outside of the nipple, fixes the fixing plate 10 on the fixing plate 10, and fixes the sheath 3 in the milk duct to provide a channel for the milk ductoscope; of course, the fixing component can also open a through hole communicating with the inside and outside at the right end of the side wall of the protective sleeve 5, pass a trachea through the through hole, install an air valve on the trachea, and after putting the protective sleeve 5 on the nipple, connect the negative pressure device to the trachea, extract the excess gas in the protective sleeve 5, make the inner wall of the protective sleeve 5 fit the nipple, and improve the fixing effect of the protective sleeve 5.

[0026] When using this embodiment, the expansion tube 2 is inserted into the expansion tube 2, the second fixing block 9 is against the right side of the fixing plate 10, the central tube 1 is inserted into the expansion tube 2, the first fixing block 8 is against the right side of the second fixing block 9, after the nipple is locally anesthetized, the nipple is gently squeezed, the milk duct with overflowing fluid is found, the first fixing block 8 is held, the central tube 1 is inserted into the milk duct, and the second fixing block 9 is rotated to insert the expansion tube 2 into the milk duct to expand the milk duct for the first time. After the expansion tube 2 is inserted into the milk duct, the central tube 1 is held The first fixing block 8 draws the central tube 1 out of the expansion tube 2, and then the fixing plate 10 is rotated to insert the sheath tube 3 into the milk duct to expand the milk duct for the second time. After the sheath tube 3 is inserted into the milk duct, the second fixing block 9 is held to draw the expansion tube 2 out of the sheath tube 3, and the fixing plate 10 is fixed to the nipple by the fixing assembly, while the sheath tube 3 is retained in the milk duct to provide a channel for the ductoscope to avoid the milk duct from retracting after expansion, to ensure that the ductoscope can be smoothly inserted into the milk duct, and the cause of nipple discharge is detected by the ductoscope.

[0027] In this embodiment, handles may be installed on both the two fixing blocks and the fixing plate, so that the medical staff can control the fixing blocks and the fixing plate during the operation through the handles.

[0028] Example 3

[0029] This embodiment further illustrates the technology. Figure 1 and Figure 2 As shown, a silicone pad 4 is mounted on the left end of the protective sleeve 5, and the silicone pad 4 is in a hollow disc structure. When the protective sleeve 5 is put on the nipple, the silicone pad 4 is flipped over from the outer wall of the protective sleeve 5 and fit on the areola to further improve the fixing effect of the protective sleeve 5. In actual use, medical glue can also be applied on the side wall of the silicone pad 4, and the silicone pad 4 is adhered to the areola by the medical glue to improve the fixing effect of the protective sleeve 5.

[0030] Example 4

[0031] This embodiment further illustrates the technology. Figure 1 and Figure 2 As shown, the left end of the expansion tube 2 has an inverted bevel, and the left end of the expansion tube 2 is in an inclined state. The outer diameter of the left end of the expansion tube 2 is smaller than the outer diameter of the right end of the expansion tube 2. When the expansion tube 2 is inserted into the milk duct, the left end of the expansion tube 2 with a smaller outer diameter is first inserted into the milk duct, and the expansion tube 2 is rotated back and forth, similar to the twisting method of silver needles in traditional Chinese medicine, so that the expansion tube 2 is slowly inserted into the milk duct, and the milk duct is slowly expanded. While achieving the purpose of milk duct expansion, tearing of the milk duct is avoided.

[0032] In this embodiment, the left end of the sheath tube 3 adopts the same structure, which also plays the effect of slowly dilating the milk duct and protecting the patient.

[0033] Example 5

[0034] This embodiment further illustrates the technology. Figure 1 As shown, the right side walls of the fixing plate 10 and the second fixing block 9 are inlaid with metal blocks 6, and the right side walls of the fixing plate 10 and the second fixing block 9 are both provided with grooves, and the two metal blocks 6 are respectively inlaid in the corresponding grooves;

[0035] The corresponding metal block 6 is inlaid with a magnetic block 7 for adsorbing the metal block 6 on the left side wall of the second fixed block 9 and the first fixed block 8; the metal block 6 on the right side of the corresponding fixed plate 10 is provided with a groove on the left side wall of the second fixed block 9, in which the magnetic block 7 is inlaid; the metal block 6 on the right side wall of the corresponding second fixed block 9 is provided with a groove on the left side wall of the first fixed block 8, in which the magnetic block 7 is inlaid; the first fixed block 8, the second fixed block 9 and the fixed plate 10 are connected together through the adsorption effect of the magnetic block 7 on the metal block 6, so that the doctor does not need to keep the three fixed blocks stable at the same time during the operation, simplifies the operation steps, and improves the efficiency and safety of the operation. The metal block 6 is made of a material that can be adsorbed by the magnetic block 7, such as iron.

[0036] Example 6

[0037] This embodiment further illustrates the technology. The length of the sheath 3 is 1.5 cm to 2 cm. The length of the sheath 3 will affect the patient's safety and the accuracy of the operation. A longer sheath 3 will cause the sheath 3 to contact the patient's breast, affecting the subsequent ductoscope examination of the breast. A shorter sheath 3 will make it difficult for the doctor to control the sheath 3 and will not play a role in maintaining the milk duct channel. The length of the sheath 3 can be selected to be any length between 1.5 cm, 2 cm, 1.7 cm and 1.5 cm-2 cm. The length of the sheath 3 should be selected to be as easy as possible for the doctor to operate while ensuring the patient's safety.

[0038] The outer diameter of the central tube 1 is 0.5 mm to 0.6 mm, and the outer diameter of the central tube 1 is the same as the diameter of the No. 5 lacrimal duct probe. The outer diameter of the central tube 1 can be selected from any length between 0.5 mm, 0.6 mm, 0.55 mm and 0.5 mm-0.6 mm. In the prior art, the nipple is expanded by the No. 5 lacrimal duct probe. The outer diameter of the central tube 1 is the same as that of the No. 5 lacrimal duct probe, and plays the same role as the lacrimal duct probe.

[0039] The inner diameter of the sheath 3 is 1 mm to 1.1 mm, and the inner diameter of the sheath 3 is the same as the diameter of the No. 10 lacrimal duct probe. The inner diameter of the sheath 3 can be selected to be any length between 1 mm, 1.1 mm, 1.05 mm and 1 mm-1.1 mm. In the prior art, the final expansion of the nipple is performed by expanding the No. 10 lacrimal duct probe, and the inner diameter of the sheath 3 is the same as it, and a channel of the same diameter is formed, so that the ductoscope can be smoothly inserted into the nipple duct.
