Description
Technical field
The utility model belongs to technical field of medical treatment mechanical, and in particular to a kind of 3D printing for Minimally Invasive Surgery is oriented to
Plate.
Background technology
Radiotherapy (radiotherapy) is for one of critical treatment method of tumour.It is secondary anti-in order to reduce radiotherapy to greatest extent
Should and radiotherapy normal tissue damage, develop seeds implantation technology i.e. seeds implanted.Seeds implanted is
One kind allows it with the treatment means of destroyed tumor by inside radioactive source implantation tumour.Seeds implanted treatment technology is related to radioactive source,
Its core is radion.Seeds implanted relies primarily on orientation system by radioactive prospecting instrument knurl body, passes through miniature radiation
Source sends lasting, short-range radioactive ray, tumor tissues is killed to greatest extent, and normal structure is not damaged or only micro-
Small loss.
Current seeds implanted operation is typically clinically to be carried out by rule of thumb by doctor, this Couple herbs just to doctor and
Skill proposes very high requirement.Traditional Inner irradiation in the image-guided lower progress of CT is performed the operation, due to exist tens so that on
In hundred points of puncture, 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 into needle passageway progress to puncturing, and can not calculate the prescribed dose of particle, this just usually makes
(dosage is too small to be caused for inside tumor appearance " hot-zone " (dosage is excessive to cause side effect) and/or " cold-zone " after into seeds implanted
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 there can be the skew of sufferer position during patient performs the operation from be checked to implementing or tumour increase is reduced
Situation, when implementing operation, be present deviation in the original guide plate good through 3D printing and actual knub position, cause original through 3D
The guide plate of printing can not be continuing with, and cause the unnecessary wasting of resources, while the operation preparation time of extension.
As can be seen here, can not enough there is provided a kind of improved 3D for Minimally Invasive Surgery of structure based on of the prior art
Guide plate is printed, it is effectively solved because of the situation that sufferer position is offset or tumour increase is reduced, and 3D printing can not be used
The problem of guide plate is accurately positioned, as those skilled in the art's technical barrier urgently to be resolved hurrily.
Utility model content
In order to solve the above-mentioned technical problem there is provided a kind of 3D printing guide plate for Minimally Invasive Surgery for the utility model.Can
After according to CT scan, apply art doctor and puncture needle track using auxiliary to carry out radion plant according to the skew selection of sufferer position
Enter.Reply sufferer position drift condition still is able to be continuing with original 3D printing guide plate.
In order to reach above-mentioned technique effect, the utility model includes following technical scheme：
A kind of 3D printing guide plate for Minimally Invasive Surgery, including the guiding substrate mutually agreed with people's external surface, it is described
Guiding substrate is provided with multiple lead columns and multiple auxiliary puncture in needle track, the lead column and are provided with puncturing hole, each to be oriented to
Multiple auxiliary are set to puncture needle track around post.
It is that medical worker is based on tumor presence that auxiliary, which punctures needle track, and the reply knub position set around lead column is inclined
When shifting or change in shape, and the needle track used.Needle track is punctured by rationally setting auxiliary so that in operation, in reply disease
Suffer from position drift condition still to be able to be continuing with original 3D printing guide plate, and accurate puncture is carried out for sufferer position and send
Radion.The phenomenon for making original 3D printing guide plate not use because sufferer position is offset is avoided, and causes unnecessary
The wasting of resources and extend operation preparation time.
Further, for being provided with connecting line between the lead column of ultrasonic puncture to same CT scan layer.
When being performed the operation in order to avoid the blood vessel and bone of human body, the setting of lead column often at an angle so that
Puncture needle is punctured to relevant position by the guide effect of lead column, while the depth that the lead column of diverse location is punctured is not
Together, i.e., in the use of CT scan different layers, when medical worker is performed the operation, the design based on said structure, will
Connecting line is provided between the lead column of same depth for ultrasonic puncture pin puncture in 3D printing guide plate, namely for
Ultrasonic puncture is provided with connecting line between the lead column of same CT scan layer, enables medical personnel to directly obtain positioned at same
The lead column position of CT scan layer, and corresponding puncturing operation is carried out, facilitate medical worker to be performed the operation, when saving operation
Between.
Further, the auxiliary punctures a diameter of 1.00mm~2.50mm of needle track.
The utility model rationally sets auxiliary to puncture position and the size of needle track, and 3D printing guide board structure and original are not influenceed
There is lead column guide function, while still there is guide function to puncturing operation when sufferer position shifts.
Further, the quantity that the auxiliary punctures needle track is two or more, and linearly arrangement；It is further or every
Around individual lead column needle tracks are punctured around 2~20 auxiliary of setting.
It is further preferred that 3 or 4 auxiliary are surrounded with around each lead column punctures needle track.
Further, multiple positioning holes are provided with the guiding substrate.
