Description
Technical field
The present invention relates to human medical model fields, practice model and its manufacturer specifically for a kind of tumor resection
Method.
Background technique
Various intraorganic good/malignant tumours have become the multiple illness of one kind of modern.Due in intraorganic tumour
Resection operation is sufficiently complex, nearby there is a large amount of nerve, blood vessel, lymph node, thus needs to carry out before really for patient's operator
Largely practices and view and emulate to accumulate enough clinical experiences.
And the source of the operation practice of intern is usually various animals at present, however the organ of animal construction and human body
There are larger differences, thus practice effect is bad；It furthermore is to be autopsied, however the source of corpse is few, it is difficult to meet
The wilderness demand of intern；And due to situation about being difficult to see that inside organ, thus both the above practice is not appropriate for newly
The doctor of hand carries out operation practice.
Furthermore the preoperative planning of tumor patient is generallyd use at present is that CT or MR are scanned, due to being layer-by-layer disconnected
Face image, or even operating doctor can not all find out the state of an illness of patient from image completely, and only those have received professional training
Image department doctor can just understand the meaning in image, and since image is not intuitive enough, in many times Different hospital to same
There are subjectivity, state of an illness evaluation obtained, which exists, to be entered and left for the interpretation of one patient's scan image.This has just seriously affected operation doctor
Raw and family numbers of patients is to the operation resolution of patient and the selection of Surgical treatment.
Summary of the invention
First invention purpose of the invention is: a kind of tumor resection practice model is provided, it being capable of real simulation
The construction of operation organ, and can directly see the position of tumour clearly from outside, convenient for teaching and operation practice；
Second goal of the invention of the invention is: a kind of tumor resection practice molds, methods of making is provided, it can
The model for producing a kind of real simulation sufferer operation organ tumor, determines to the operation of patient convenient for operative doctor and family numbers of patients
Disconnected and Surgical treatment selection, and can allow doctor that real simulation operation practice is repeated in the preoperative.
First invention purpose of the present invention is achieved through the following technical solutions: a kind of tumor resection practice model, special
