Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, is specifically related to a kind of radiocurable pair of water pocket apparatus for wave-energy source.
Background technology
Plesioradiotherapy, it is radiocurable a kind of form, radioactive source can be positioned over exactly within malignant tumor or near, high-energy ray is utilized to kill and wound tumor cell, there is direct killing tumor, therapeutic effect is good, relapse rate is low advantage, be widely used in the treatment of clinical tumor.For cancer of anal canal or rectal cancer, usual employing is treated built with the apparatus for wave-energy source of radioactive source, apparatus for wave-energy source is stretched in anal canal or in rectum, again radioactive source is imported in apparatus for wave-energy source, radioactive source in apparatus for wave-energy source carries out radiotherapy to the cancerous tissue affected area in anal canal or rectum, this apparatus for wave-energy source needs the cancerous tissue focus be close in anal canal or rectum, improves radiotherapeutic effect good.But existing apparatus for wave-energy source adopts pmma material or other transparent rigid materials to be made, and there is following problem:
1, because malignant tumor is attached on anal canal or rectum, for the malignant tumor outstanding to intracavity, because apparatus for wave-energy source is rigidity, when apparatus for wave-energy source is entering in anal canal and intrarectal process, apparatus for wave-energy source easily punctures malignant tumor tissue, causes Malignant tumor of bonal metastasis; For to the recessed malignant tumor of intracavity, this apparatus for wave-energy source does not contact carninomatosis stove, produces certain distance with carninomatosis stove, makes radiotherapeutic effect poor.
2, the apparatus for wave-energy source of this rigidity can sharp patient, makes patient quite painful over the course for the treatment of.
3, the cost of this apparatus for wave-energy source is high, usually needs to reuse, therefore there is the risk of cross infection.
And we observe at tumor focus often amesiality in practice, if make irradiated area control the normal mucosa at perilesional accept as far as possible little irradiation, the normal skin tissue near focus just can be avoided to be subject to excessive radiation and damaged, cause radioactivity early complication.
Equally, for the radiotherapy of intravaginal tumor, also there is an identical difficult problem.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of radiocurable pair of water pocket apparatus for wave-energy source, this radiocurable pair of water pocket apparatus for wave-energy source can improve therapeutic effect, and cost is low, and alleviates the misery of patient.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of radiocurable pair of water pocket apparatus for wave-energy source, it is characterized in that: comprise the cylindrical shape protection capsule be made up of pellosil, the patient end silica gel lid sealing of described protection capsule, the machine end silica gel plate of described protection capsule seals, in described cylindrical shape protection capsule, a silica gel partition walls is set, protection capsule is separated into two axially extended water-injecting cavities, wherein the first water-injecting cavity and the second water-injecting cavity not connected, the section of described silica gel partition walls is curved, described silica gel partition walls forms four supply radiator ducts extended vertically and insert chamber, four supply radiator ducts insert chamber and are equally distributed in semicircle segmental arc, line angle between the center of circle in adjacent two chambeies and the protection capsule center of circle is 60 degree, the axial two ends of silica gel partition walls are connected with silica gel plate with silica gel lid respectively, described supply radiator duct inserts chamber and is positioned at the sealing of silica gel lid one end, the other end extends the insertion opening that silica gel plate forms supply radiator duct, described silica gel plate is provided with the first water filling port be communicated with the first water-injecting cavity and the second water filling port be communicated with the second water-injecting cavity, formed and execute source protection device by dilation by water injection.
Described silica gel is covered with the seal plug inserting chamber for sealing supply radiator duct.
Described silica gel partition walls, silica gel lid and silica gel plate are one-body molded.
