Abstract
The utility model discloses a kind of guiding die plates with auxiliary needle track, including the template made of 3D printing technique, multiple plan needle tracks are provided in template, fluorescence reference axis is provided in template, the origin of fluorescence reference axis is provided with fixed needle track, corresponding each plan needle track is provided with unique number, and the position of plan needle track is being provided with virtual needle track.There is the utility model the guiding die plate of auxiliary needle track to be provided with virtual needle track, and increased virtual needle track increases serious forgiveness when can make up dislocation subtle with human body because of template, avoids the contraposition for adjusting template and human body again in art.With suitable guide post passage length the error of inserting needle is reduced, while not influencing the operation in operation.Fixed pin under fixed needle passageway is set, template is relatively fixed with body position.
Description
Technical field
The utility model relates to the technical fields of minimally invasive medical, are specifically one kind in seeds implanted surgical procedure
The auxiliary tool of application.
Background technique
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 for radioactive prospecting instrument
In knurl, lasting, short-range radioactive ray are issued by mini-radioactive resource, kill tumor tissues to greatest extent, and just
Normal tissue does not damage or only microlesion.
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, 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 to the progress of inserting needle channel is punctured 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
For above-mentioned shortcoming and defect in the prior art, the purpose of this utility model is that developing one kind in seeds implanted
The guiding die plate with auxiliary needle track 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 auxiliary needle track, 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, close to plan needle track
Position be provided with virtual needle track.
Preferably, the plan needle track is to have guide post channel, and the guide post protrudes from template upper surface, the guidance
The length of column is 1.8~2.3cm.
Preferably, the virtual needle track is no guide post channel.
Preferably, the length of the guide post is 2cm.
Compared with prior art, the utility model embodiment has at least the following advantages:
Guiding die plate with auxiliary needle track is provided with virtual needle track, and increased virtual needle track can make up because of template and people
Increase serious forgiveness when the subtle dislocation of body, avoids the contraposition for adjusting template and human body again in art.Suitable guide post passage length
So that the error of inserting needle reduces, while the operation in operation is not influenced.And using fixed pin under fixed needle passageway, by template with
Body position is relatively fixed, and fixed pin is also with guide post channel.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the guiding die plate that the utility model has auxiliary needle track；
Fig. 2 is the schematic diagram of the section structure for the guiding die plate that the utility model has auxiliary needle track.
Specific embodiment
Below 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 auxiliary needle track, 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, in the position close to plan needle track 2
It installs and is equipped with virtual needle track 3.
When the effect of virtual needle track 3 is to occur in surgical procedure template 1 and good patient position contraposition non-100%, from
Plan 2 inserting needle of needle track, which can not may accurately reach tumour position, causes particle dose inadequate, and increased virtual needle track 3
It may be more suitable for inserting needle and reach tumour position to supply dosage, serious forgiveness can be increased by virtual needle track 3, avoided in art
In adjust the contraposition of template 1 Yu human body again.
The effect of fixed needle track 4 is then across 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 also used to determine template 1 and patient relative position
Repeatability.Bone label: tomography of the bone of patient on image shows that the path of inserting needle selects the position close to bone as far 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.
And plan the corresponding unique number of needle track 2 using etching technique marking in template 1, convenient for identification plan needle in art
2 position of road improves identification speed, avoids the communication cost between physics teacher and doctor.
The plan needle track 2 is to have guide post channel, and the guide post 6 protrudes 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 6 is longer, inserting needle
Error with regard to smaller, but it is too long will affect surgical procedure, therefore more preferably length is 2cm.
The virtual needle track 3 is no guide post channel.Virtual needle track 3 against the setting of plan needle track 2 (distance about 1~
2mm), it will lead to the bad differentiation plan needle in art if being intended to needle track 2 and virtual needle track 3 is provided with guidance main channel
Road 2 and virtual needle track 3, influence to operate.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone 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 protection scope of the utility model should
Subject to the scope of protection of the claims.
