Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a novel breast dilator suitable for breast endoscopy. Background Technology
[0002] Breast diseases have become one of the most common diseases among women. Nipple discharge is one of the most common clinical symptoms of breast diseases. The shape, color, and causes of nipple discharge are diverse. Among them, unilateral, single-orifice, bloody, and pathological discharge have a higher probability of cancer. Therefore, examination after nipple discharge is inevitable. Breast duct endoscopy is an examination of the breast using a breast duct endoscope. It can clarify the cause of nipple discharge and treat it at the same time. Early detection and timely treatment of breast tumors can avoid the huge pain of later treatment such as mastectomy.
[0003] Ultra-fine fiber ductoscopy allows for clear observation of the mammary duct walls and lumen secretions. If space-occupying lesions are present, their color, size, shape, and smoothness can be described. Ductoscopy is convenient, minimally invasive, and provides direct visualization, effectively improving the diagnostic rate of lesions protruding within the mammary ducts. The general clinical procedure involves disinfection and local anesthesia, followed by the use of multiple lacrimal duct probes of varying sizes, from fine to coarse, to gradually dilate the ducts before inserting a very thin ductoscope through the discharge opening. Ductoscopy involves inserting an endoscope through the opening of the mammary duct and observing the condition within the ducts on a medical monitor while probing towards the terminal duct, reaching as far as the fourth or fifth-order branches.
[0004] The above-mentioned method has the following drawbacks: during the process of nipple dilation, the nipple dilator needs to be kept as upright as possible, but medical staff need to change the size of the dilator probe multiple times, which can easily cause the probe to move or tilt, leading to patient discomfort. Therefore, a new type of breast dilator suitable for breast endoscopy is proposed to solve the above problems. Utility Model Content

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a sliding frame, which is slidably connected to the top inner wall of the ring frame. A telescopic spring is fixedly connected to one outer wall of the sliding frame. A rotating rod is rotatably connected to one inner wall of the sliding frame via a bearing. A pressure roller is fixedly connected to the rotating rod. An adjusting plate is slidably connected to the bottom inner wall of the sliding frame. A small spring is fixedly connected to one outer wall of the adjusting plate. A limit rod is fixedly connected to the outer wall of the adjusting plate away from the small spring.
[0008] As a further description of the above technical solution: there are two support rods, and the two support rods are respectively hinged to the inner walls of the left and right sides of the bra frame.
[0009] As a further description of the above technical solution: the end of the compression spring away from the T-shaped plate is fixedly connected to one end of the mounting bracket, and the T-shaped plate penetrates the inner wall of one side of the serial port.
[0010] As a further description of the above technical solution: the auxiliary tape is slidably connected to the inner side wall of the serial port, and the T-shaped plate is snapped onto the outer side wall of the auxiliary tape.
