Vagina forming model and method of 3D printing preparation therefor

Abstract

The invention provides a vagina forming model which comprises: a pipe body of a hollow columnar structure; a head of a hollow structure, wherein the head is integrally and smoothly shaped with one endof the pipe body, the circumferential outer surface of the head is an ellipsoidal surface, and the side far from the pipe body is round and is an inward concave arc face; a tail of a hollow structure, wherein the tail is smoothly and integrally shaped with the other end of the pipe body, and the outer surface of the tail is an arc face; a plurality of annular bulges which fixedly sleeve the pipebody at an equal interval along the axial direction of the pipe body, wherein the outer surface of each annular bulge is an arc face; a liquid inlet which is disposed at the center of the inward concave arc face of the head; and a liquid outlet which is disposed at the center of one side, far from the pipe body, of the tail. The invention also provides a method of 3D printing preparation for the vagina forming model, wherein the method can determine parameters of a die of the vagina forming model based on a BP neural network so as to realize subsequent preparation of the vagina forming model.

Description

technical field [0001] The invention relates to the technical field of medical supplies, and more specifically, the invention relates to a vagina forming model and a 3D printing preparation method thereof. Background technique [0002] Patients with congenital absence of vagina are obstructed by internal or external factors during embryonic development, and may also be caused by abnormal development of paramesonephric duct due to gene mutation (possibly with family history). Quality of life, normal sex life, the commonly performed operation is sigmoid colon replacement vaginoplasty, the postoperative "vagina" is actually a bowel tube, but if the patient has no sex life, or has no sex life for a period of time, the bowel tube is prone to adhesion, leading to the failure of the operation. [0003] To solve this problem clinically, ham sausage + condom, or 20ml disposable empty needles are often used to make a simple model, and let the patient insert the "vagina" to open the in...

Problems solved by technology

This structure is a mold used in the vaginal shaping operation. If you still use this structure in the future, it will not only be troublesome to operate, but also not suitable for going out or in public places, which will bring great inconvenience to the life of the patient.
