Description
Technical field
This utility model is related to the calibrating installation that a kind of processing meanss of radiation or radiation are treated, specifically a kind of radioactivity grain
Sub- implantation positioning device.
Technical background
Seeds implantation is less invasive techniques for the treatment of malignant tumor, and because its wound is little, therapeutic effect is good,
Clinically it is widely used at present.Radioactive prospecting instrument technology it is critical only that accurately puncture technique, only
Realize equidistant accurately puncture, in tumor tissues, radioactive particle could be carried out well-regulated cloth source, thus on the one hand
Avoid the excessive damage to surrounding tissue for the radioactivity, on the other hand ensure the effective illuminated dosage to tumor.Radioactive particle is planted
Enter how treatment completes at present under the positioning of the image technologies such as ct, ultrasonic, nuclear magnetic resonance, NMR, piercing method includes tradition puncture
Method and Template Location piercing method.Traditional piercing method is that operator relies on good anatomical knowledge and operation skill and technique to realize swelling
The cloth source of the puncture of tumor and radioactive particle, its advantage is that flexibility ratio is high, can manual control puncture position and puncture angle；But its
Affected substantially by anthropic factor, operator's individual diversity alienation is notable, and the controllability in particle cloth source is poor；And for adjoining
Important blood vessels, the tumor tissues of internal organs, often become the forbidden zone of tradition puncture.Template Location piercing method is domestic extrapolation at present
High seeds implantation method, its advantage has: 1, accurate positioning, can be accurate to millimeter；2nd, operability is good, can be real
Now equidistant particle cloth source；3rd, repeatable high, can achieve standardized particle cloth source between different operating person, it is to avoid anthropic factor is led
The particle cloth source diversity causing, impact therapeutic effect assessment.Needle localization template can be divided into conventional template and 3d template at present, its
Respectively there are pluses and minuses.Conventional template, cost is relatively low, reusable, but Needle localization and fixation are more complicated, and interference factor is more,
Need certain training time could grasp；Meanwhile, conventional template is difficult to accomplish completely sterile working in brachytherapy.
As patent cn201260737, cn203107988, and patent cn101773411, cn203609748 has separately designed flexible
Frame joint and even bed puncture positioning device, but the patient accepting treatment can not have any activity on ct machine, otherwise point of puncture with
Puncture and be susceptible to displacement between template, lead to Needle localization failure.Additionally, the stop that tumor is organized by bone is often tradition
The obstacle that template punctures, at this moment needs to punch using bone drill, and this operation is destructive greatly.3d template is current research
Focus, such as patent cn102895732 " a kind of radioactive prospecting instrument template and preparation method thereof " pass through the image system such as ct, mr
Describe tumor relative position and body surface model, then corresponding puncture template and corresponding puncture are printed using 3d printing technique
Duct.This puncture template is good with the identical property of sites, is fixed conveniently, punctures precision higher.But 3d template is personalized
Customization, needs some cycles, expense is high simultaneously, acceptable patient is less；If additionally, patient midway abandoning cure,
Template there is a problem of wasting.In addition, the puncture duct of 3d template is designed in advance, duct number according to seeds implanted plan
And duct angle is fixing, in operation, often it is difficult newly to select duct and vernier angle, duct lacks and leads to need to reseed particle temporarily
Difficulty, and angle mismatches and tends to lead to the situation of duct card pin.
Content of the invention
This utility model be related to a kind of radioactive prospecting instrument positioner it is intended to ensure cheap cost of manufacture while,
Realize strict sterile working during radioactive prospecting instrument it is ensured that simple and direct, stable and accurately Needle localization is it is ensured that operation
The motility of process is same with repeatability.
For reaching object above, this utility model adopts the following technical scheme that and is achieved:
A kind of radioactive prospecting instrument positioner, including rotary template and device for positioning and securing.
Further, described radioactive prospecting instrument positioner is made up of transparent material.
Further, described rotary template includes bar column template (1) and rotary shaft (2).
Further, described bar column template (1) main body is cylinder, the equidistant through hole of spaced 5mm in template.
Further, described bar column template (1) can be rotated centered on rotary shaft (2).
Further, described riser (3) flanking central is penetrating translot, and rotary shaft is placed on translot realizes rotating mould
Plate and the connection of device for positioning and securing；
Further, described riser (3) riser top center is fluted；
Further, described angle indicator (4) is semicircle, and its graduated disc is -90 ° -90 °, upper angled instruction
Pin (8).
Further, angle indicator (4) is placed in the groove in riser central authorities, and angle indicator can slide in groove.
Further, there is level indicator (9) in the middle of described reinforcement (5).
Further, there is fastening screw (10) at described rotary shaft (2) two ends.
Further, described elevating lever (6) and reinforcement (5) two ends, both adopt threaded (11), are risen by rotation
Fall bar (6) realizes elevating function.
Further, it is connected using universal drive shaft (12) between described elevating lever (6) and soft callosity (7), universal drive shaft fastens
The fixing universal drive shaft (12) of screw (13) rotates.
