Description
Technical field
The utility model relates to medical appliance field, especially a kind of precisely goal-oriented ear canal cancer radiotherapy applicating device for curing.
Background technique
When carrying out the treatment of certain cancers, it is sometimes desirable to by the release of radiopharmaceuticals particle in the target area for having tumour, benefit
Tumour cell (cancer cell) is killed with the radioactivity of radiopharmaceuticals particle.When the tumour grown in treating ear canal, swell sometimes
The position of tumor is deeper, it is necessary to radiopharmaceuticals particle is placed into radiotherapy guide hole using tool (radiotherapy applicating device for curing) and completed precisely
Targeted therapy.Traditionally radiopharmaceuticals particle can be generally coated in flexible material, then using structure similar to Medical forceps
Applicating device clamp radiopharmaceuticals particle, and drug particle is protruded into human body, and be eventually placed at tumour.This mode is in reality
Many problems are exposed in the application process of border: if there are errors for releasing position, influencing therapeutic effect；Radiopharmaceuticals particle is entering
During human body, if the healthy cell with human body contacts, it may destroy or unhealthful cell；Working efficiency is low,
It once can only discharge a drug particle etc..Therefore a kind of method or apparatus for being able to solve the above problem is needed now.
Summary of the invention
The utility model is to propose that a kind of structure is simple to solve above-mentioned deficiency present in the prior art, and design is skilful
It is wonderful, it is rationally distributed, radiopharmaceuticals particle quickly and efficiently can be placed in radiotherapy guide hole and realize accurate targeted therapy, and will not
The accurate goal-oriented ear canal cancer radiotherapy applicating device for curing for allowing radiopharmaceuticals particle directly to contact with normal human tissue living cells.
The technical solution of the utility model is: a kind of precisely goal-oriented ear canal cancer radiotherapy applicating device for curing, feature
Be: the applicating device includes Hook 1, and ear canal conformable portions are connected on Hook 1, and the ear canal conformable portions include
The base surface 2 directly connecting with Hook 1 is provided with insertion section 3 on base surface 2, and guide hole 4, and institute are offered in insertion section 3
The aperture for stating guide hole 4 is 2mm.
The central axes of the guide hole 4 are straight line.
The central axes of the guide hole 4 are camber line.
The central axes of the guide hole 4 are S type curve.
The utility model compared with the existing technology, has the advantages that
A kind of precisely goal-oriented ear canal cancer radiotherapy applicating device for curing of this kind of structure type, it is simple in sturcture, ingenious in design,
Rationally distributed, it is directed to the variety of problems that conventional radiotheraphy tool is exposed during the work time, designs a kind of special column
Body structure, it is internally provided with three groups of guide holes, using these guide holes can directly by radiopharmaceuticals seeding particles to target target area,
And radiopharmaceuticals particle is all wrapped in the inside of ontology in the overall process of movement, therefore will not be with the normal tissue of human body or thin
Born of the same parents are directly contacted, to ensure that the safety of patient, the radioactivity of radiopharmaceuticals particle are avoided to make human normal part
At destruction；And its manufacture craft is simple, and manufacturing cost is cheap, it can be said that it has a variety of advantages, is particularly suitable for
In promoting and applying in the art, market prospects are very wide.

Specific embodiment
Below in conjunction with Detailed description of the invention specific embodiment of the present utility model.It is as shown in Figures 1 to 5: a kind of accurate mesh
The ear canal cancer radiotherapy applicating device for curing of guiding, including Hook 1 are marked, is connected with ear canal conformable portions on Hook 1, the ear canal is conformal
Part includes the base surface 2 directly connecting with Hook 1, and insertion section 3 is provided on base surface 2, offers and leads in insertion section 3
Hole 4, the setting open at one end of guide hole 4 is on base surface 2, and the other end is then located at the end point of insertion section 3, and the guide hole 4
Aperture be 2mm；The guide hole 4 is straight line there are three types of form, the i.e. central axes of guide hole 4；The central axes of guide hole 4 are camber line；
The central axes of guide hole 4 are S type curve, and the outer profile of insertion section 3 also coincide with the general shape of the central axes of guide hole 4, and protects
Card can be freely insertable into human antrum auris.
The course of work of the accurate goal-oriented ear canal cancer radiotherapy applicating device for curing of the utility model embodiment is as follows: by this kind
Insertion section 3 on applicating device is inserted into the ear canal of patient, and Hook 1 is hung over and is used to fix on the ear of patient, doctor
Can by the guide hole entrance on base surface 2 by radiopharmaceuticals seeding particles into guide hole 4, these radiopharmaceuticals particles pass through guide hole
After 4, accurate radiotherapy is implemented by the outlet end of 3 end of insertion section, is directly released into target region；In above process, have and put
The radiopharmaceuticals particle of penetrating property will not be contacted directly with tissue, at the same accurately and efficiently can directly discharge have it is swollen
The target area of tumor, for the release of radiopharmaceutical have many advantages, such as precisely, conveniently, normal cell will not be destroyed；
According to the difference of tumour growth position in ear canal, there are three types of forms for insertion section 3 and guide hole 4 in the present apparatus.
If the position of tumour is relatively shallower, select the axis of guide hole 4 for the insertion section 3 of straight line, directly progress radiopharmaceuticals particle
Release；If the position of tumour is deeper, in order to allow radiopharmaceuticals particle that can accurately be discharged into target area, then guide hole 4 is selected
Axis be S type curve insertion section 3, shape and track due to the 3 coincided with human body ear canal of insertion section of this shape, energy
Enough it is freely insertable into the target area of ear canal depths；And if guide hole 4 between above-mentioned two situations, is selected at the position of tumour
Axis be camber line insertion section 3.
Complete radiation therapy technology using the present apparatus, can according to the shape of ear canal cancer target area, by adjusting and
Control intensity distribution of the ray in irradiation field generate various dose gradient improve ear canal cancer target area is given it is lethal
Property high-dose irradiation, thus to tumour normal surrounding tissue control below normal tolerance dosage.It is to ear canal cancer first
Tumor target reaches the irradiation of three-dimensional conformal, and ear tumor target and neighbouring sensitive organ is followed by allow to obtain exposure dose
The adjusting of intensity and protected.
