Description
Technical Field
The utility model relates to a teaching and experimental model field especially relate to a mammary gland lump operation model.
Background
Many breast diseases, including breast cancer, fibroadenoma, lipoma, lobular tumors, etc., manifest as breast lumps before no clear pathology is established. Clinically, the nature of the breast mass is often determined by appropriate selection of a specific biopsy procedure for pathological examination based on the imaging performance of the breast mass and the associated BI-RADS classification results to determine the next treatment regimen. Biopsy surgery, including open intraoperative frozen biopsy, Fine Needle Aspiration (FNA), hollow needle biopsy (CNB), vacuum-assisted biopsy (VAB), and the like, is an effective minimally invasive technique for obtaining early pathological diagnosis, particularly ultrasound-guided VAB, and is widely used because it has small trauma, few complications, and can obtain sufficient tissue mass.
Generally speaking, the skilled manipulation technique comes from a large amount of clinical experience, the surgeon can not grow out of daily and monthly accumulated practical experience, especially the vacuum assisted breast biopsy operation, the learning curve is long, and professional training can improve the business level of the doctor. However, there are several problems to be solved at present: (1) lack of practical opportunities for surgery: in addition, the special cases that the tumor is close to the skin, the tumor is close to the nipple-areola complex, the tumor is close to the chest wall, the tumor is close to the edge of the breast and the like have less learning opportunities for the operating doctor; (2) lack of a surgical procedure skill level evaluation system: when a clinician who newly learns the VAB operation performs the VAB operation on a patient, due to less operation experience, the clinician inevitably causes residues of target lesions and excessive excision of normal tissues with different degrees, and due to the covering of postoperative hematoma and the limitation of ultrasonic images, the excision of the target lesions cannot be accurately evaluated, particularly, the situation that trace residues exist, and the recurrence of local tumors caused by the residues cannot be fed back after the recurrence. Therefore, the operation can be performed by directly walking into the clinic without mastering certain operation experience and reaching a certain technical level, which is not good and is not responsible for patients.
The highly simulated surgical model can more conveniently provide operating opportunities to the surgeon and promote the surgical level thereof. However, the existing operation models are few, mainly relate to organs such as head and neck, limbs, pelvic cavity, kidney and the like, have simple structures, and are not suitable for being used together in various operations. Breast surgery is a more urgent clinical need for a breast tumor surgery model that can simulate different tumor conditions and can evaluate the skill level of the operator. At present, no special operation model aiming at breast lump biopsy is seen at home and abroad. In order to meet the requirements of young doctors, a breast tumor surgery model capable of simulating various real human body conditions is needed, and the doctors can perform high-simulation surgery.

The instrument table-board is connected with the operating table body through the rotating pair, and can be unfolded to place surgical instruments during operation; the drawer a and the drawer b are used for storing the breast lump model and the related surgical instruments respectively.
Furthermore, the breast mass model comprises a simulated breast, a simulated mass, a simulated pectoralis major, a fixed tray main body, a fixed tray connecting module, an annular fixing ring and a fixing screw. The simulated breast is closely fixed on the fixing tray main body by the fixing screw through the annular fixing ring.
Furthermore, the simulation breast adopts the slaughtered pig breast as a raw material.
Further, the simulated mass was made of gel, the number of masses was recorded as M, the volume of the mass was recorded as V, the location of the mass was recorded as d1 from the nipple, distance from the skin as d2, distance from the pectoralis major muscle as d3, and distance from the edge of the breast as d 4. The values of M, V, d1, d2, d3 and d4 may be set as needed to mimic various pathological conditions that may be encountered clinically, particularly clinical scenarios of masses near the nipple, skin, pectoralis major, outer edges of the breast, and multiple masses.
Further, the simulated pectoralis major is made of thin rubber.
As the preferred scheme of the utility model, the simulation breast can also select the breast of other mammals after slaughtering.
The utility model has the advantages that:
(1) a high-simulation breast tumor surgery model is provided, which can simulate various tumor conditions existing clinically;
(2) the model can be suitable for various biopsy operations of breast surgery, including open operation-intraoperative frozen biopsy, FNA, CNB and vacuum-assisted biopsy (VAB), and the like, and has wide applicability; it is convenient to provide the breast surgeon with operational opportunities and to promote the level of their surgery.
(3) In addition, after the operation is finished, the operation model can be subjected to page-shaped cutting along the position of the tumor, the residual amount of the tumor and the excessive excision amount of normal tissues are quantitatively recorded by combining the condition of the lesion of the tumor and the condition of the tissue bar cut by rotation, and systematic evaluation indexes are provided for the teaching of the breast surgery and the evaluation of the operation technical level by combining the recorded indexes such as the operation time, the occurrence condition of complications (such as skin damage) and the like. By combining the evaluation indexes, young doctors receiving the operation model for training can enter the clinic to perform clinical operation under the condition of mastering certain operation experience and reaching certain technical level. Therefore, the method has remarkable significance and great social benefit for improving the teaching quality of the breast surgery, perfecting the operation teaching evaluation system and ensuring the diagnosis and treatment quality of the patient.
