This invention provides a pelvic floor support structure model and modeling method based on three-dimensional data to assist in judging the condition of pelvic floor ligaments and to perform physical simulation. To solve the above-mentioned technical problems, this invention provides the following technical solution, including: a bone structure, which includes the hip bone and the coccyx, which together form a pelvic support structure, with the inner side of the hip bone and the coccyx forming the pelvic space; an organ structure, which includes the following model structures, including models of the uterus, bladder, vagina, and rectum located in the pelvic space; and a ligament structure, which includes the cardinal uterine ligament connecting the uterus to the hip bone, the uterosacral ligament connecting the uterus to the coccyx, and the round uterine ligament, which connects one end to the upper end of the uterus and extends obliquely upward at the other end.

The utility model discloses an auxiliary treatment device for posterior malleolus fracture, the auxiliary treatment device for posterior malleolus fracture is a self-shaping anti-slip steel plate, the self-shaping anti-slip steel plate is matched with a human posterior malleolus bone, and a plurality of screw holes are formed in the self-shaping anti-slip steel plate; through the design of the self-shaping anti-skid steel plate, the steel plate can be combined with the ankle joint of a patient to fix the ankle joint, the anatomical form of the posterior ankle is met, the ligament structure is not interfered, self shaping can be achieved in the operation, low incisura is achieved, and irritation to soft tissues such as posterior tendons is reduced or even eliminated, so that the medical cost is effectively reduced; the device has the advantages of being capable of accelerating the rehabilitation process of the wounded, good in fixing effect and good in self-plasticity.

This invention relates to the field of medical education technology, and discloses an interactive teaching system and method for simulating the biomechanical changes of the cervical spine in people who frequently look down at their phones. The system includes a physical model module, a sensing and control module, and a software visualization module. The physical model module is constructed as a movable cervical spine model, incorporating ligament structures and flexible tubular structures to simulate nerves or blood vessels. The sensing and control module drives the cervical spine model to produce flexion or extension movements via a drive mechanism, and collects biomechanical data during the cervical spine movement using pressure sensors, angle sensors, and tension sensors. The software visualization module receives the sensor data, drives the virtual 3D cervical spine model to move synchronously, and displays the data as a pressure distribution map and angle-pressure relationship curves. When the pressure reaches a preset threshold, a simulated intervertebral disc herniation demonstration is triggered. This invention demonstrates the changes in cervical spine curvature and intervertebral disc stress under different head-down postures, and is suitable for medical teaching and popular science demonstrations.
