[0002] A tumor is a new organism formed when a cell in a local tissue loses normal growth regulation at the genetic level under the influence of various carcinogenic factors, leading to its clonal abnormal proliferation. Tumor puncture refers to a puncture biopsy, which is a puncture to obtain a tissue biopsy for pathological examination under the guidance of B-ultrasound or CT. When B-ultrasound or CT finds a mass in the body, if it is suspected to be a malignant tumor, a tumor puncture biopsy is required.

A real-time simulation device and method for tumor puncture according to any one of claims 1 to 7, characterized in that: The following steps are involved: Step 1: When in use, the third simulation block (23), the second simulation block (22) and the T-shaped block (25) at the lower end of the first simulation block (21) are respectively inserted into the T-shaped groove (24), and the tumor simulation ball (27) is randomly adhered to the receiving holes (26) opened on both sides of the second simulation block (22) by glue, and the third simulation block (23), the second simulation block (22) and the first simulation block (21) are moved to one side of the first clamping block (51), and the tumor simulation balls (27) connected to both sides of the second simulation block (22) are clamped and fixed through the receiving holes (26) opened by the third simulation block (23) and the first simulation block (21), and the tumor simulation balls (27) are randomly clamped and fixed to simulate the position of the patient's tumor; Step 2: insert the protrusion (56) at the lower end of the second clamping block (52) into the limiting block (55), rotate the fixing screw (58) into the screw hole (57), connect the second clamping block (52) and the limiting block (55) through the fixing screw (58), put the simulated skin (31) into the storage groove (32) and insert the clamping block (33) into the gap between the third simulation block (23), the second simulation block (22) and the first simulation block (21), turn on the driving motor (7), drive the threaded rod (53) to rotate in the sliding groove (510), and the threaded rod (53) is moved in the sliding groove (510). The nut (54) is driven in the groove (510) to move in the direction of the first clamping block (51), and the nut (54) drives the limit block (55) and the second clamping block (52) to move toward the side of the first clamping block (51), and the third simulation block (23), the second simulation block (22) and the first simulation block (21) are clamped and fixed by the first clamping block (51) and the second clamping block (52), so that the number of the second simulation blocks (22) can be increased, and the length of the third simulation block (23), the second simulation block (22) and the first simulation block (21) can be adjusted to simulate patients of different heights; Step 3: The B-ultrasound machine body (34) and the display body (36) are turned on. The B-ultrasound machine body (34) detects the third simulation block (23), the second simulation block (22) and the inside of the first simulation block (21) through the detector (37), and displays the irradiation result through the display body (36). The personnel judge the position of the tumor simulation ball (27) through the display result of the display body (36). After the judgment is completed, the box door (43) at the upper end of the storage box (41) is opened, and the alcohol cotton (42) in the storage box (41) is taken out. The simulated skin (31) and the surface of the simulated puncture needle (38) are disinfected by the alcohol cotton (42). Before the simulated puncture, The patient's skin and the puncture needle are disinfected. After disinfection, the used alcohol cotton (42) is poured into the waste recovery barrel (44), and the simulated puncture needle (38) punctures the simulated skin (31). The solid dye (9) inside the simulated skin (31) adheres to the simulated puncture needle (38). When the simulated puncture needle (38) touches the tumor simulation ball (27), the solid dye (9) adheres to the tumor simulation ball (27). The drive motor (7) is started to drive the threaded rod (53) to rotate in the opposite direction, and the first clamping block (51) is separated from the second clamping block (52). Whether the simulated puncture is successful can be determined based on whether the solid dye (9) is adhered to the surface of the tumor simulation ball (27); Step 4: Remove the simulated skin (31) from the receiving groove (32), remove the tumor simulation ball (27) from the receiving hole (26), rotate the fixing screw (58) out of the screw hole (57), remove the second clamping block (52) from the limiting block (55), remove the third simulation block (23), the second simulation block (22) and the T-shaped block (25) at the lower end of the first simulation block (21) from the T-shaped groove (24), remove the third simulation block (23), the second simulation block (22) and the first simulation block (21), and complete the disassembly of the device.
