Abstract
The invention discloses a tissue equivalent filler for cancer radiotherapy, which is prepared by mixing liquid paraffin and a styrene-ethylene-butadiene block copolymer to obtain a mixture, and heating and curing the mixture to obtain the tissue equivalent filler; the mass fraction of the styrene-ethylene-butadiene block copolymer in the mixture is 3-20%. The tissue equivalent filler can be in contact with the body of a patient in a fitting manner, no air bubbles exist between the tissue equivalent filler and the body of the patient, meanwhile, the tissue equivalent filler has better transparency, and a doctor can see marks on the body of the patient through the tissue equivalent filler, so that the accuracy and the uniformity of radiation dose are improved.
Description
Technical field
The present invention relates to a kind of medical instruments field, and in particular to a kind of tissue equivalent's filling for cancer radiation therapy
Thing.
Background technology
Up to the present, the treatment method of cancer includes operative treatment, radiotherapy, chemotherapy, hormone therapy, gene
Treatment and immunization therapy etc..Wherein, operative treatment, radiotherapy, chemotherapy has turned into Main Means.
Radiotherapy（Abbreviation radiotherapy）It is exactly to use high energy particle or ray, such as x-ray or gamma-rays are thin to kill cancer
Born of the same parents, so that treating cancer.Radiotherapy only has the history of decades, but development is very fast.It is auxiliary due to the use of super-pressure therapy apparatus
The improvement of assistant engineer's tool and the accumulation of experience, therapeutic effect are significantly improved, and the most important hand in treatment of cancer has been turned at present
One of section.
At present, about 70% cancer patient needs to use radiotherapy during treating cancer, there are about 40% cancer
Can be effected a radical cure with radiotherapy.Effect and status of the radiotherapy in oncotherapy become increasingly conspicuous.Radiotherapy has turned into treatment and has disliked
One of Main Means of property tumour.
In some cancers（Such as breast cancer）Patients During Radiotherapy in, for ensure dose of radiation it is accurate and uniform, to some because
The patient of missing is organized, it is necessary to use a kind of tissue equivalent's filler material to fill at tissue missing, makes radiation target dose
Distribution is more accurate and uniform.The conventional tissue equivalent's filler of clinic is paraffin wax, vaseline, special silica gel etc., and breast cancer is used
Tissue equivalent's filler typically uses special silica gel.
At present, the tissue equivalent's filler used in domestic hospitals is essentially all external import product, and is all deposited
In a universal shortcoming, contact of tissue equivalent's filler with patient body be not docile, so as in tissue equivalent's filler
There is bubble and patient body between, thus have influence on the accuracy and uniformity of dose of radiation.
The content of the invention
The present invention provides a kind of tissue equivalent's filler, snugly can be contacted with patient body, make itself and patient body it
Between do not exist bubble, and with the preferable transparency, can allow doctor that the mark on patient body is seen through tissue equivalent's filler
Note.
The invention discloses a kind of tissue equivalent's filler for cancer radiation therapy, by atoleine and styrene-
Ethylene-butadiene block copolymer is mixed to get mixture, is heating and curing and obtains described tissue equivalent's filler；The mixing
The mass fraction of styrene ethylene butadiene block copolymer is 3~20% in thing.
Styrene ethylene butadiene block copolymer is dispersed in liquid by the present invention using atoleine as carrier
In paraffin, tissue equivalent's filler surface prepared by cured shaping has appropriate viscosity and soft durometer, thus can be with docile
Be attached to the skin surface of patient, and ensure there is no bubble between tissue equivalent's filler and skin.
Preferably, also include dispersed SiO 2 powder in described mixture, for adjusting tissue equivalent
The density of filler, is required with meeting the different of client.
Preferably, the number-average molecular weight of described styrene ethylene butadiene block copolymer is 7~220,000, it is described
Mixture in styrene ethylene butadiene block copolymer mass fraction be 3~10%, more preferably 5%.
Preferably contacted to make the bottom surface of tissue equivalent's filler have with the body surface of patient, make its between patient body not
There is bubble, and with the preferable transparency, tissue equivalent's filler is shaped as terrace with edge or round platform, thickness is 2~
15mm。
Because the surface of the tissue equivalent's filler for preparing relatively is glued, doctor's operation and storage for convenience can be in the tissue
Has macromolecule membrane at least one surface of equivalent filler, when using, by only macromolecule membrane need to be taken off directly
Use.
Preferably, described macromolecule membrane is polyethylene film, polyvinyl chloride film, polyurethane film, poly- to benzene
Naphthalate film or silica gel thin film, the macromolecule membrane species that upper and lower surface has can be with identical, it is also possible to different.
Further preferably, the upper and lower surface of tissue equivalent's filler has macromolecule membrane simultaneously, and thickness is 0.01
~0.5 millimeter.
In for the Patients During Radiotherapy of breast cancer, in order that tissue equivalent's filler has with the body surface of patient preferably contact,
Shape by described tissue equivalent's filler is more preferably five terrace with edges；Further to improve the effect of radiotherapy, by thickness
Preferably 4~12mm.The top surface of five terrace with edges and bottom surface are pentagon, when using, pentagonal one side are placed along armpit,
So that whole tissue equivalent filler is snugly positioned over patient body-surface.
Compared with prior art, it is simply practical the beneficial effects of the invention are as follows design, it is easy to use.It can not only be solved
Existing tissue equivalent's filler is not docile with human contact, alveolate between patient body-surface and tissue equivalent's filler to lack
Point, and tissue equivalent's filler of the invention is more transparent, and doctor can be allowed to see on patient body through tissue equivalent's filler
Mark.
