Description
Technical field
This utility model belongs to technical field of medical equipment, more particularly to a kind of radioactivity for ocular tumor treatment
Eyeshield.
Background technology
Ocular tumor is mainly common with retinoblastoma with melanoma of choroid, these intraocular malignant
Once make a definite diagnosis eyeball extraction operation at once.With the development and the change of medical idea for the treatment of technology, carry out outside sclera in recent years
Apply the closely various replacement Therapeutic Method such as radiation treatment (PRT).PRT is mainly by performing the operation the radiation containing radioactive source
Property eyeshield (or applicator) is fixed on scleral surface, makes radioactive source part accurately be directed at ocular tumor, intraocular tumour is carried out
In-plant radiotherapy, after the radiological dose needed for ocular tumor is received, then applies the ophthalmically acceptable of implantation by operation
Patch device takes out.The method has tumor section radiation dose height, treatment time short, evident in efficacy and regarding for eye is suffered from energy preservation part
Power, damage to normal structure in eye socket that little, relapse rate is low, little to patient face and part and psychological impact, it is simple and easy to do to perform the operation
The advantages of, progressively become the effectively treatment means for the treatment of intraocular tumour.
The radioapplicator (eyeshield) for being used for ocular tumor treatment earliest is three-decker, now by radioactive sealed seed source
In as groove, the groove that then will be equipped with radioactive sealed seed source sticks to flexible liner, and liner is sticked to metal finally
Protection is made by by shell.Its shortcoming is that manufacturing process is complicated, wayward；It is by being adhesively joined between three-decker, stable
Property is not high, has easily caused radioactive sealed seed source and has come off or lose；Radioactive sealed seed source fixed position not precision, can cause
Dose distribution does not know, so as to affect therapeutic effect；Due to complex manufacturing process, staff's radiation dose height etc. is caused to lack
Point.Chinese patent CN203647879U discloses a kind of ophthalmically acceptable applicator, is the liner and by gold by made by medical silica-gel material
What the protection of category material was constituted by shell, be to be fixed in medical silica-gel material in the groove of lining, so radioactive sealed seed source
It is used for adhesive of medical afterwards to be bonded liner with metal by shell, while metal is reduced by the fixture of shell.Although the applicator
Structure was simplified than former technology, while the groove for providing more immobilization of radioactive sealed seed sources can be crossed.But, there is doctor in it
It is connected unstable by shell with metal with silica gel material liner；There is radioactive sealed during shell adhesion with metal in medical material liner
The possibility that seed source easily scatters or loses；Liner is offset by inner liner location during shell adhesion with metal and causes Radiation dose distribution inclined
Move, so as to affect therapeutic effect；Multiple radioactive sealed seed sources cause because of seed source irradiation or high-temperature sterilization during treating
The liner deformation that medical silica-gel makes causes radioactive sealed seed source distribution to change, and causes therapeutic effect not good or exists
The potential risk that side effect occurs.
