Embodiment Construction

[0053] The prostate, bladder, rectum, obturator internal muscle, and levator ani muscle, which have a great influence on the positioning of the prostate, are selected as objects for 3D reconstruction and optimization. Combined with the knowledge of pelvic anatomy, the MR images obtained by T2WI imaging were processed in the medical image processing software MIMICS TM Manual segmentation and 3D reconstruction were performed in 10.01. Then import the obtained 3D point cloud of organ group into Geomagic Studio 2012 for surface processing, and export the 3D model of organ group in the form of NURBS surface by adjusting a series of parameters such as smoothness threshold and stress threshold.

[0054] Based on the knowledge of anatomy, the constraints and connections between the organs in the model are determined, and the 3D reconstruction is optimized in the CAD software, and the casting molds for each organ are designed. The rapid prototyping technology of laser sintering is use...

Abstract

The invention relates to a manufacturing method of a male pelvic organ group entity model. The method comprises the steps of three-dimensional reconstruction of a medical image of a male pelvic organ group, designing and manufacturing of a single organ casting mold; selection and preparation of a single organ material and casting of a single organ; assembly of the single organ; internal environment simulation of a human pelvic cavity; and completing of manufacturing of the pelvic organ group entity model and experimental verification of the mechanical property of the pelvic organ group entity model. The male pelvic organ group entity model is highly consistent with the human actual condition in the aspects of pelvic organ structure and mechanical property, and can be applied to research of the total puncture force of the pelvic cavity and the deformation theory and simulated operation training; the problems that a living tissue is constrained by ethics and law are solved; the blank of a pelvic organ group entity model development technique is filled; and the manufacturing method has very wide application prospect in clinical medicine and experiment research.

Description

technical field [0001] The invention relates to the fields of anatomy, computer science and technology, bionic tissue materials and the like. Specifically, based on prostate puncture surgery, design and manufacture a solid model of male pelvic organ groups that conforms to the internal and external environment of the pelvis as much as possible, and can be applied to puncture mechanics experiments and puncture surgery training. Background technique [0002] Percutaneous surgery is one of the most commonly used minimally invasive treatments for prostate brachytherapy. Due to the flexible constraints of surrounding organs, the prostate gland, which is the target organ in puncture surgery, is not fixed in position, and has complex boundary conditions and deformation mechanisms. Therefore, the environment of the pelvic organ group where the prostatic body is located is the key to the accuracy of the operation. Preoperative training, measurement planning, and experimental resear...
