Abstract

The invention discloses a 3D printing cervix dilatation simulation model, and relates to the technical field of cervix dilatation. The model comprises a bottom plate, wherein an anti-skid pad is fixedly connected at four corners of the lower surface of the bottom plate, the upper surface of the bottom plate is fixedly connected with the lower surface of the top plate through four support rods, theupper surface of the top plate is overlapped with the lower surface of the connecting plate, and the upper surface of the connecting plate is provided with four first through holes. A 3D printing cervix dilatation simulation model By setting the slide bar, sliding sleeve, sphere, orifice of uterus, cervical module and uterine module, so that the diameter of the cervix can be enlarged from 1 cm to10 cm, When the diameter of the cervix is enlarged to 10 cm, The sphere is completely located in the uterine orifice, which makes the sliding rod drive the sphere downward and away from the uterine orifice. Using 3D printing technology, on the basis of the original plan, through 3D imaging technology, the real-time change of uterine orifice dilation can be observed intuitively, so that the students can understand the progress of labor process, and make the clinical teaching more intuitive.

Description

technical field

[0001] The invention relates to the technical field of opening the cervix, in particular to a 3D printed cervix expansion simulation model. Background technique

[0002] Opening the cervix, the professional name is dilatation of the cervix. During labor, the uterus contracts regularly, pulling the uterine muscles and surrounding fibers of the cervix. In addition, the amniotic sac in front of the fetal presentation is wedge-shaped, causing the cervix to go upward. Expanding outward, the cervical canal gradually shortens until it disappears. The external cervical os is usually only the size of a fingertip. As the labor progresses, the external cervical os expands to a diameter of 10 cm, allowing the full-term fetal head to pass through. Called the opening of the cervix.

[0003] In the process of clinical education and guidance of childbirth, the size of the dilation of the cervix and the tolerance of the cervix are relatively abstract for medical staff. When ...
