Description
Technical field
A kind of the utility model technical field of medical treatment mechanical, and in particular to 3D printing guide plate for Minimally Invasive Surgery.
Background technique
Radiotherapy (radiotherapy) is one of the critical treatment method for tumour.It is secondary anti-in order to reduce radiotherapy to the maximum extent
It answers and the damage of radiotherapy normal tissue, develops seeds implantation technology i.e. seeds implanted.Seeds implanted is
It is a kind of by inside radioactive source implantation tumour, allow it with the treatment means of destroyed tumor.Seeds implanted treatment technology is related to radioactive source,
Its core is radion.Seeds implanted relies primarily on orientation system in radioactive prospecting instrument knurl, passes through miniature radiation
Source issues lasting, short-range radioactive ray, kills tumor tissues to greatest extent, and normal tissue is not damaged or only micro-
Small loss.
Current seeds implanted operation is clinically usually to be carried out by rule of thumb by doctor, this just to the Couple herbs of doctor and
Skill proposes very high requirement.Traditional Inner irradiation operation carried out under CT images guidance, due to there are tens so that on
Hundred points of puncture, in art substantially " blind to wear ".In addition, the current tumour seeds implanted planning system that oneself has be all based on it is one-dimensional
Or bidimensional image data are pre-planned to the progress of inserting needle channel is punctured, and can not calculate the prescribed dose of particle, this just usually makes
" hot-zone " (dosage is excessive to lead to side effect) and/or " cold-zone " occur inside tumor after seeds implanted, (dosage is too small to be caused
Adverse consequences to no effect).In order to solve the above-mentioned technical problem, in the prior art based on 3D printing technique produce it is coplanar,
The puncture template of non-co-planar, different needle angles is gradually applied to clinic.
But existing 3D printing guide plate is when in use, and the guide plate printed is hard material and structure is fixed, by
In the durations such as patient tumors position, posture and breathing can and the data of acquisition there are some deviations, simultaneously because tumor patient is sick
Other complex situations of feelings feature, it, which punctures needle track, during surgery to do corresponding adjustment according to the actual conditions of operation.And show
The 3D printing guide plate of some hard materials is difficult to solve the problems, such as this, can not according to circumstances adapt to during surgery puncture needle track
Property adjustment.
It can be seen that deficiency in the prior art can be based on, provide a kind of structure the improved 3D for Minimally Invasive Surgery
Guide plate is printed, the accuracy of 3D printing guide plate and patient body-surface positioning is effectively improved, it during surgery can be according to patient's feelings
Condition appropriate adjustment punctures the puncture angle of needle track, improves Minimally Invasive Surgery success rate, and save operating time, becomes art technology
Personnel's technical problem urgently to be resolved.
