Vascular-level reproduction has become a reality. The
torso sex doll modeled by medical imaging has an intercostal muscle texture accuracy of 0.2mm, and even restores the cross-fiber direction of the rectus sheath. Even more shocking is the 3D-printed spinous process structure. Each vertebra has an independent buffer silicone pad built in, which can present a real bone undulation when pressed. Some
new sex dolls even integrate bionic organ packs: silicone livers and kidneys are suspended in damping fluid, and displacement feedback consistent with anatomical positions is generated during palpation. Surgeons have confirmed that the palpation accuracy of such models used in medical training is 68% higher than that of traditional teaching aids.
