Problems solved by technology

However, there are currently the following problems to be solved: (1) Lack of surgical practice opportunities: there are not so many surgical practice opportunities in clinical practice. Special cases, such as tumors close to the edge of the breast, have fewer opportunities for surgeons to learn; (2) Lack of an evaluation system for surgical operation skills: when clinicians who are new to VAB surgery perform VAB surgery on patients, due to l

Embodiment 1

[0028] Such as Figure 1-3 as shown in Figure 1-3 As shown, a breast lump operation model includes an operating table body 2, on which drawers a7 and drawers b8 are installed; the operating table body 2 is connected to the instrument table 9 through the rotating pair 6; the operating table body 2 The two sides of the top surface are respectively provided with an operating table connecting module 3, the operating table connecting module 3 is connected to the operating table body 2 through a lockable universal joint 4, and the top surface of the operating table body 2 is provided with a breast lump model 1, Breast lump model 1 comprises fixed tray main body 14, and fixed tray main body 14 two ends are installed with fixed tray connecting module 15, and fixed tray connecting module 15 is installed on the operating table connecting module 3 by connecting screw 10, and fixed tray main body 14 top surface is provided with Simulation breast 11, simulation breast 11 is provided with...

Embodiment 2

[0038] In the case that other parts are the same as those in Embodiment 1, the difference between this embodiment and Embodiment 1 is that the simulated breast 11 can be stored in a refrigerator. Refrigerated storage has better surgical results because it is not fixed with fixative; however, it is only suitable for short-term use because it is not fixed with antiseptic.

Embodiment 3

[0040] In the case that other parts are the same as those in Embodiment 1, the difference between this embodiment and Embodiment 1 lies in that the artificial breast 11 can be preserved with a new type of specimen preservation solution. The new specimen preservation solution is 0.5% chitosan (main active ingredient), 0.1% sodium diacetate, 0.15% dodecyltrimethylammonium chloride, 1% potassium nitrate, 0.5% sodium sulfate, 1.5% ethylene diacetate alcohol for compounding. Among them, chitosan is the only basic polymer in natural polysaccharides, which has excellent biocompatibility. Chitosan has strong antibacterial activity against various bacteria and fungi, and is widely used in the field of medicine. The whole and free specimens using the new preservation solution have natural color, soft texture, strong hygroscopicity and no mildew phenomenon. The preservation solution is always clear and transparent, the muscles and ligaments tend to be soft, and the toughness and elastic...

Abstract

The invention discloses a breast mass operation model. The breast mass operation model comprises an operating table vehicle body, wherein operating table connection modules are arranged on the two sides of the top surface of the operating table vehicle body; the operating table connection modules are connected with the operating table vehicle body through universal joints; a breast mass model is arranged on the top surface of the operating table vehicle body, wherein the breast mass model comprises a fixed tray main body; fixed tray connection modules are installed at two ends of the fixed tray main body, and the fixed tray connection modules are installed on the operating table connection modules through connection screws; and a simulated breast is arranged on the top surface of the fixedtray main body, and the simulated breast is fixed on the fixed tray main body through an annular fixing ring. According to the breast mass operation model provided by the invention, the model can besuitable for simulating various biopsy procedures of breast surgery, comprising freeze biopsy, FNA, CNB, vacuum assisted biopsy and the like in an open operation-during operation, and has wide applicability; and convenience is brought to a breast surgeon by providing an operation opportunity and the surgical level thereof can be improved.

Description

technical field [0001] The invention relates to the field of teaching and experiment models, in particular to a mammary gland mass operation model. Background technique [0002] Many breast diseases, including breast cancer, fibroadenoma, lipoma, phyllodes tumor, etc., present as breast masses before the pathology is clear. In clinical practice, specific biopsy operations are often selected reasonably based on the imaging manifestations of breast masses and related BI-RADS classification results for pathological examination to clarify the nature of breast masses and determine the next treatment plan. Biopsy procedures include open surgery-intraoperative frozen biopsy, fine needle aspiration (FNA), core needle biopsy (CNB) and vacuum-assisted biopsy (vacuum-assisted biopsy, VAB). Effective minimally invasive techniques for pathological diagnosis, especially ultrasound-guided VAB, are widely used for their small trauma, few complications, and sufficient tissue volumes. [00...
