Problems solved by technology

The ductoscopy system involves a lot of equipment, and the configuration cost is high. At the same time, the operation of the ductoscopy inspection is complicated. The endoscope used for inspection is easily damaged due to its small diameter. The biggest problem with this equipment is that it cannot be used. Effective fixation, when the internal pressure of the breast duct is too high, it is easy to cause the endoscope to slip, which is not conducive to diagnosis; and glutaraldehyde is required for 30-40 minutes before use, which limits the wide use of large areas each time, and the waiting time is long. Currently, it is routinely carried out There are not many hospitals for this examination, which cannot meet the examination needs of many patients

Embodiment 1

[0025] Such as Figure 1 to Figure 3 As shown, a mammary duct positioning device includes an outer sleeve end piece 1, an outer sleeve 6, an annular balloon 3, a ceramic sleeve 11, and a guide wire 12 arranged in the catheter.

[0026] Outer sleeve 6 is made of TPU material, 80 mm, outer diameter 1 mm, with narrow cavity 5 inside, outer sleeve 6 is provided with a branch tube 7, one end of branch tube 7 is open, and the other end is connected with outer tube 6 cavity 5 connected. The branch pipe 7 is sequentially connected with a valve, a flexible pipe and a 5ml syringe.

[0027] The annular balloon 3 is arranged at the front end of the overtube 6, and the inside of the annular balloon 3 is a filling cavity 4 communicated with the lumen 5. The lumen 5 of the overtube 6 and the front end surface of the overtube 6 have at least one connection port, and each connection The mouth corresponds to a connecting tube, which communicates with the filling cavity 4 of the annular balloo...

Embodiment 2

[0034] This embodiment is basically the same as Embodiment 1, and the improvement is that the cooperation between the porous member and the inner wall of the ceramic inner core is further optimized.

[0035] Please refer to figure 1 , Figure 4 As shown, the front end of the guide wire 12 is provided with a protrusion matching the concave surface. The concave surface of the porous member 8 is a conical surface 15, and the porous member 8 is provided with a number of narrow holes 16 distributed radially from the center. The concave surface of the porous member 8 accommodates one or more patina balls, which are made of flexible film material and contain specific solutions such as physiological saline and methylene blue. The radial narrow hole design prevents clogging and facilitates solution outflow.

[0036] In order to further improve the tightness of the connection, a slot structure is also provided between the front end of the outer sleeve 6 and the annular balloon 3, and...

Abstract

The invention discloses a mammary duct positioning device, which comprises an outer casing, an annular balloon, an end part of the casing, a ceramic sleeve core, and a guide wire arranged in the catheter; A porous part that limits the limit distance of the guide wire moving forward is fixed in the sleeve core, and the porous part can accommodate the coated ball of methylene blue reagent. The positioning device is easy to operate and low in cost. It assists the operator to display the direction of the lesion duct and the distance from the nipple before the operation, formulates the operation plan for the operator before the operation, and assists the complete resection of the lesion during the operation.

Description

technical field [0001] The invention relates to a diagnostic device in the medical field, in particular to a breast duct positioning device. Background technique [0002] Breast cancer is one of the most common malignant tumors among Chinese women, and its incidence has been on the rise in the past 10 years. The key to the treatment of breast cancer lies in the early detection, early diagnosis and early treatment of the disease. That is, timely treatment at the early stage of the disease is of great help to the healing of breast cancer and the improvement of the quality of life. [0003] Nipple discharge is one of the common abnormalities of the breast, and it is often associated with intraductal lesions of the breast, which are also closely related to the development of breast cancer. Nipple discharge is divided into two categories, physiological discharge and pathological discharge (Pathological Nipple Discharge, PND). Pathological discharge usually manifests as unilate...
