The invention discloses a
simulation device for
mammary gland rotary
cutting needle or puncture needle training under
ultrasound, and relates to interventional instruments such as rotary
cutting needles and puncture needles, the
simulation device comprises an outer
skin, a filler, a
simulation lump, a bottom plate and an anti-skid module, the outer
skin is arranged on the upper surface of the bottom plate, the filler is arranged in the outer
skin, the simulation lump is arranged in the filler, and anti-skid modules are symmetrically mounted on the lower surface of the bottom plate. According to the invention, the tissue texture can be simulated under the ultrasonic image, and under the observation of the ultrasonic image, the tumor implantation can realistically simulate the ultrasonic image of the breast benign
mass. A rotary
cutting needle or a puncture needle can be used for excision, no obvious needle passage or cavity is left in an ultrasonic image when the rotary
cutting needle or the puncture needle is pulled out, the real simulation of training is improved, the
hardness of the simulated lump is controlled to show a water-containing
solid under
ultrasound, and the simulated lump can be
cut off by the rotary
cutting needle or the puncture needle and pulled out through a negative pressure pipeline.
