Description
Technical field
The present invention relates to tumour radiotherapy technical fields, and in particular to a kind of shaping seeds implanted 3D guide template.
Background technique
Radioactive particle treats existing more than 100 years history of tumour, and radioactive particle is carried out under percutaneous puncture, to target
It is additional that area or danger zone can carry out in due course particle in art, and risk organs position or position can effectively evade, really real
It is higher tumor target dosage is showed, normal surrounding tissue damages smaller radiotherapy theory.Preliminary Practice proof can achieve
Good salvage treatment target, side reaction can receive.Presently, there are the problem of be: 1. plain CT guides lower radioactive particle to plant
Enter more according to personal experience ingredient, due to rib cage or dissection destructing interference, particle needle transplanting arrangement is caused to be extremely difficult to
It is complete parallel；2. seeds implanted is to be carried out according to preoperative therapy plan, and patient body position in actual operation, respiratory movement or go out
Blood, pneumothorax etc. can cause seeds implanted and preoperative plan in art to there is very large deviation；3. patient body-surface form is different, same
The each body surface of patient is also different, is entirely capable of and the matched seeds implanted guide template of body surface without one kind.
Summary of the invention
For the above-mentioned deficiency of the prior art, the present invention provides a kind of accurate positionings, the accurate shaping of seeds implanted
Seeds implanted 3D guide template.
