Abstract
The utility model discloses a kind of guiding die plates with hollow design, including the template made of 3D printing technique, it is provided with reference axis and multiple plan needle tracks in template, the origin of reference axis is provided with fixed needle track, multiple hollow holes are additionally provided in template.There is the utility model the guiding die plate of hollow design to use fretwork technology, convenient for whether there is or not bleedings in observation art, save material；Emergent needle track can be also done to use.With suitable guide post passage length the error of inserting needle is reduced, while not influencing the operation in operation.Fixed pin under the fixed needle passageway of setting, template and body position are relatively fixed.
Description
Technical field
The utility model is related to the technical fields of minimally invasive medical, be specifically one kind in seeds implanted surgical procedure
The auxiliary tool of application.
Background technology
In the prior art, radiotherapy (radiotherapy) is one of the critical treatment method for tumour.In order to greatest extent
Ground reduces the damage of radiotheraphy secondary reaction and radiotherapy normal tissue, develops (the following letter of seeds implantation technology
Claim seeds implanted).
Seeds implanted is a kind of by inside radioactive source implantation tumour, allows it with the treatment means of destroyed tumor.Seeds implanted
Treatment technology is related to radioactive source, and core is radion.Seeds implanted relies primarily on orientation system by radioactive prospecting instrument
In knurl, lasting, short-range radioactive ray are sent out by mini-radioactive resource, tumor tissues is made to be killed to greatest extent, and just
Normal tissue does not damage or only microlesion.
Current seeds implanted operation is typically clinically 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 guiding, since there are several or even several
Ten, a points of puncture up to a hundred, in art substantially " blind to wear ".In addition, current existing tumour seeds implanted planning system is all base
It is pre-planned into needle passageway progress to puncturing in one-dimensional or bidimensional image data, the prescribed dose of particle can not be calculated, this is just
There is " hot-zone " (dosage is excessive to lead to side effect) and/or " cold-zone " (dosage mistake in inside tumor after often resulting in seeds implanted
It is small to cause to no effect) adverse consequences.
Utility model content
Disadvantage in for the above-mentioned prior art and deficiency, the purpose of this utility model is that exploitation one kind is in seeds implanted
The guiding die plate with hollow design that auxiliary punctures in surgical procedure.
The purpose of this utility model is achieved through the following technical solutions：
A kind of guiding die plate with hollow design, including the template made of 3D printing technique, are arranged in template
There are reference axis and multiple plan needle tracks, which is characterized in that the origin of reference axis is provided with fixed needle track, is also set up in template
There are multiple hollow holes.
Preferably, the plan needle track is to have guide post channel, the guide post to protrude from template upper surface, the guiding
The length of column is 1.8~2.3cm.
Preferably, the length of the guide post is 2cm.
Preferably, the fixed needle track is to have guide post channel, and the length of the guide post is 2cm.
Compared with prior art, the utility model embodiment has at least the following advantages：
1. fretwork technology saves material convenient for whether there is or not bleedings in observation art；Emergent needle track can be also done to use.
2.. suitable guide post passage length makes the error of inserting needle reduce, while not influencing the operation in operation.
3. using fixed pin under fixed needle passageway, template and body position are relatively fixed.
Description of the drawings
Fig. 1 is the structural schematic diagram for the guiding die plate that the utility model has hollow design；
Fig. 2 is the cross-sectional view for the guiding die plate that the utility model has hollow design.
Specific implementation mode
With reference to Fig. 1 and embodiment, the utility model is described in further detail, following embodiment be it is descriptive, no
It is restrictive, protection scope of this utility model cannot be limited by this.
A kind of guiding die plate with hollow design, including template 1 made of 3D printing technique, set in template 1
It is equipped with reference axis 5 and multiple plan needle tracks 2, the origin of reference axis 5 is provided with fixed needle track 4.
The effect of fixed needle track 4 is then to pass through fixed needle track 4 that template 1 is opposite with body position solid using fixed pin
It is fixed, it is generally perpendicular to horizontal plane when in use, is marked close to patient bone；It is additionally operable to determine template 1 and patient's relative position
Repeatability.Bone marks：Tomography of the bone of patient on image shows that the path of inserting needle selects the position close to bone as possible
It sets.Because bone structure is small relative to soft-tissue motion degree, the relationship of the position and bony structure that determine inserting needle ensure that into
The repeatability of needle path diameter and intended path.
Multiple hollow holes 3 are additionally provided in template 1.Hollow hole 3 convenient in the course of surgery observation puncture position whether there is or not
Bleeding, while material is also ad save, reduce the cost of template 1.And appearance plan needle track 2 is not suitable for inserting needle in the course of surgery
When, hollow hole 3 can also be made needle track inserting needle of meeting an urgent need.The shape of hollow hole 3 is not unique, can be regular circular, rectangle
Or other regular polygons, can also be any other irregular shape.
The plan needle track 2 is to have guide post channel, the guide post 6 to protrude from 1 upper surface of template, the guide post 6
Length be 1.8~2.3cm.Guide post 6 can be such that the error of inserting needle reduces.Although for theoretically, guide post is longer, inserting needle
Error with regard to smaller, but it is long can influence surgical procedure, therefore more preferably length is 2cm.Corresponding fixed needle track is also to have to draw
The length in guide post channel, the guide post is 2cm.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
Subject to the scope of protection of the claims.
