Abstract
The utility model relates to a for the closely radiotherapy apparatus of the mentally deficient photon skin applicator of " rigidity " iodine - 125, the mentally deficient photon type skin disease therapentic equipment of appellation " flexibility " iodine - 125 is called for short " mentally deficient photon skin applicator of flexible iodine - 125 ". It comprises 125I kind component (or title seed source), source support, source frame, pressure frame and backing. Utilize the mentally deficient gamma -ray (or calling mentally deficient photon) of the interior a plurality of iodine - 125 that set up of this skin applicator kind of component transmission, shine the skin disease tissue, reach therapeutical purpose. The biggest technical characteristics of this type skin applicator is except that inlaying iodine - 125 kind of component in hold in the palm in the source for the rigidity parts, and all the other parts all have the flexibility, therefore when clinical use, suitably bending to adopt medical bonding dressing to fix better on skin lesion tissues. Mentally deficient photon skin applicator of flexible iodine - 125 provides for the skin disease patient and new face, a non - operation, do not have painful, more nimble treatment means.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments.It is more particularly the dermopathic radiotherapy apparatus of a kind of application therapy.But it is different from again existing " rigidity " iodine-125 lower energy photon skin plaster device, appellation " flexibility " iodine-125 lower energy photon skin plaster device, is called for short " flexible iodine-125 lower energy photon skin plaster device ".
Background technology
For multiple dermatosis treatment radioactive skin applicator, Britain last century the eighties have " rigidity "
90sr/
90y skin plaster device product (utilizes
90sr/
90the β ray of Y radioactive source release carries out application therapy).Russia once studied and used modified glass-fiber sorption
90sr/
90y nucleic, then dresses up one " flexibility " medical application device with Aluminium Foil Package, but has no formal product supply market.China, in the early 1990s, establishes powder metallurgical technique manufacture
90sr/
90the production line of Y skin plaster device, and start to supply national Ge Jia hospital.See documents " DevelopmentofSr-90/Y-90SurfaceApplicatorsbyPowderMetallu rgicalTechnology ", CaiShanyu, SunYuhua, GaoWanshan, et.al, J.Radional.Nucl.Chem, Articles, 1996,25 (1): 113-120.
In view of current domestic Strontium-90 raw material supply existing problems, consider
125energy release characteristic X-ray during I decay, namely
125te-kX ray (energy is between 27.4-31.4KeV) and gamma-rays (energy is 35.5KeV), the penetration capacity in tissue higher than
90sr/
90y β ray (being 12mm to the maximum), can reach 17-20mm, be very suitable for brachytherapy.Because China has grasped the production technology of iodine-125 seed source (or claiming Iodine-125 Seed), and be formally applied to clinical, therefore can directly utilize iodine-125 seed source to manufacture skin plaster device.Last year, we succeeded in developing " rigidity " iodine-125 lower energy photon skin plaster device, on this basis, developed again and were easier to clinical " flexibility " iodine-125 lower energy photon skin plaster device that should use.
Summary of the invention
The flexible iodine-125 lower energy photon skin plaster device that maximum feature of the present invention is made up of iodine-125 seed source, source holder, source frame, press box and backing, except the iodine-125 sealed seed source producing low-energyγ-ray is that remaining part all has " flexibility " except " rigidity " parts.
In the present invention, in order to make gamma radiation field be evenly distributed, be 2 × 2cm in active region
2area in, devise the 3 kinds of medical grade silicon rubber holders evenly inlaying more than 20 seed sources and do source holder.
In the present invention, source frame, press box and backing all adopt lead equivalent to be the lead rubber of 0.25mmPb or 0.35mmPb, can meet the shielding requirements of lower energy photon, guarantee the radiation safety of medical worker and patient during medical treatment.
Flexible iodine-125 lower energy photon skin plaster device of the present invention can suitably bend, and is convenient to adopt medical bonding dressing to be fixed in patient skin diseased tissues.
Accompanying drawing explanation
Fig. 1. the configuration diagram of flexible lower energy photon skin plaster device.
Wherein: 1-backing, 2-source frame, 3-
125i seed source, 4-source is held in the palm, 5-press box.
Fig. 2. the source holder structure figure (three kinds of patterns) of seed source can be inlayed.
Detailed description of the invention
Here is embodiment:
This utility model, flexible lower energy photon skin plaster device by backing (1), source frame (2),
125i seed source (3), source holder (4) and press box (5) composition (referring to the configuration diagram of flexible lower energy photon skin plaster device).
This utility model employs routine
125i sealed seed source, its diameter is 0.8mm, and length is 4.5mm, and wall thickness is 0.5mm, and adopt titanium alloy material to make involucrum, sealing is implemented at two ends.Source holder adopts that medical grade silicon rubber is special forms, and can inlay more than 20
125i seed source, they are evenly arranged in 2 × 2cm
2in the active region of area, total activity can make as requested (general control is in 8-40mCi scope).
Be inlaid with
125the source holder of I seed source combines with source frame, press box, backing and is namely assembled into flexibility
125i lower energy photon skin plaster device.Its overall dimensions are 36 × 36mm, and gross thickness is 3 ~ 4mm, and gamma-rays illumination window (i.e. active region) is of a size of 20 × 20mm.
Above-mentioned flexible skin applicator parts are except iodine-125 seed source is rigid element, and other is flexible material.Wherein source holder adopts medical grade silicon rubber material; Source frame, press box and backing employing lead equivalent is the lead rubber material of 0.25mm or 0.35mmPb.
The flexible iodine-125 lower energy photon skin plaster device that this utility model is shown, can use medical bonding dressing to be fixed on dermatosis tissue when treating.Required irradiation time and irradiation number of times, needed for different skin disease, therapeutic dose is determined.
If when patient's pathological changes tissue surface is long-pending larger, subregion can be taked to irradiate and to cover with the mode successively superposed comprehensively, avoid occurring heavy district and blind area.
