Description
Technical field
The utility model relates to radiotherapy equipment technical fields, and rectum is expanded when more particularly to for radiotherapy
Expand intestines device.
Background technique
When uterine neck malignant tumour radiotherapy, adjacent organs especially rectum by amount usually it is relatively high, usually can all connect
Nearly V50=50%, minimum flow is also close to 40GY so that entire rectum is all very high by measuring, therefore in radiotherapy patient's rectum pair
It is very high to react incidence, reacts also obvious, so being badly in need of method to solve the problems, such as that rectum is too high by measuring in radiotherapy.
Utility model content
The technical problems to be solved in the utility model is to overcome the shortcomings of the prior art, when providing for radiotherapy
Expand the expansion intestines device of rectum.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme:
The expansion intestines device that rectum is expanded when for radiotherapy, including one for protruding into outer tube in anus, in the outer tube
It is fixedly connected with an inner tube, the both ends of said inner tube are set on the outside of the outer tube, and one end of said inner tube connects an air bag, inner tube
The other end be used to connect the compact side inflator of the gas injection toward the air bag in, be equipped on the outside of the outer tube in one end of separate air bag
One is equipped with the box body of lubricating fluid, and cassette upper end opening and the upper end are equipped with one by the lid of opening sealing, under the box body
End offers liquid outlet, and corresponding liquid outlet is equipped with sealing cover.
Preferably, the compact side inflator includes bobbin, epicoele will be divided into bobbin by a separation column in the bobbin
And cavity of resorption, the epicoele are equipped with a piston, the piston is fixedly connected with a piston rod by nut, the separation column equipped with into
Port, one can block one end of the briquetting connecting spring of the air inlet, the other end connecting spring seat of spring, the spring
Seat be fixed on it is described under it is intracavitary, when spring force be 0 when, the briquetting can block the air inlet, the cavity of resorption bottom end just
The gas nozzle that connection one is connected to cavity of resorption.
Preferably, the sealing cover connects a connecting rod, the connecting rod is fixedly connected on the outer tube lateral wall.
Preferably, the outer tube is cylindrical shape.
Preferably, said inner tube is cylindrical shape.
Preferably, being equipped with the scale for measuring length on the outside of the outer tube.
Preferably, said inner tube is equipped with gas flow meter.
Beneficial effect is: rectum itself is a hollow natural cavity, is in contraction state under natural conditions, at this moment
Whole rectum volume is smaller, and in treating rectum have be very close to tumor target, so entire rectum by very high according to measuring,
Therefore, in uterine neck malignant tumour radiotherapy, air bag is brought near rectum by outer tube, is inflated by compact side inflator
So that air bag is full, so that rectum sufficiently struts, expand the volume of entire rectum, so that opposite intestines of the rectum close to tumor target
Wall area becomes smaller, and the irradiated area being subject to is also opposite to become smaller, and to reduce being measured by shining for entire rectum, reduces rectum side reaction hair
It is raw.

Specific embodiment
The utility model is described further presently in connection with Figure of description.
It is as shown in Figure 1 it is a kind of for radiotherapy when expand the expansion intestines device of rectum, including one for protruding into anus
Outer tube 1, an inner tube 2 is fixedly connected in the outer tube 1, and the both ends of said inner tube 2 are set to 1 outside of outer tube, said inner tube 1
One end connect an air bag 3, the other end of inner tube 2 is used to connect the compact side inflator 4 of the gas injection in the air bag, the outer tube
The box body 5 that 1 outside is equipped with lubricating fluid equipped with one in one end far from air bag 3,5 upper end opening of box body and the upper end are equipped with one
