A protective device for intracavity radiotherapy of gynecological tumors

Abstract

The invention relates to a radiation therapy protection device for gynecological tumor cavity, which comprises a plastic column, a central tube, a main radiation tube, an auxiliary radiation tube, a plastic column support and a protective sleeve; the plastic column is a porous structure mixed with radiation shielding materials ; The central tube and the auxiliary radiation tube pass through the plastic column support and are inserted into the inside of the plastic column along the axis of the plastic column; a radiation source is arranged inside the main radiation tube and / or the auxiliary radiation tube; the radiation shielding material is placed between the central tube and the A specific position of the auxiliary radiation tube is provided with a notch, which allows the radiation emitted by the radioactive source to pass through; the side wall of the central tube is provided with a plurality of penetration holes, and the end of the central tube left outside the plastic column support is connected to the fluid pump The fluid pump is used to send fluid into the center tube and enter the space between the protective sleeve and the outer peripheral wall of the plastic column through the permeable hole and the plastic column in turn. The fluid expands the protective sleeve, and the expanded protective sleeve moves the bladder and rectum toward Push away from the radioactive source.

Description

Technical field [0001] The present invention relates to the field of medical device, and in particular to a gynecological tumor cavity radiation therapy protection device. Background technique [0002] Common gynecological tumors have vulva tumors, vaginal tumors, uterine tumors, ovarian tumors and fallopian tumors. The incidence of gynecological tumors presents a year-on-year trend, seriously threatening women's physical and mental health. In the prior art, the gynecological tumor is used in cavity radiation treatment. Included radiotherapy is a method of introducing a radiation in a tumor site through a human natural cavity path, such as a vaginal, rectal, etc. Intrinsic radiation therapy can be directly active on the tumor portion, allowing the tumor site to obtain a higher radiostal dose and shortened the treatment time. However, in the prior art, radiotherapy is caused by normal tissues, especially when treating vaginal tumors and uterine tumors, for bladder, rectal protecti...

AI Technical Summary

Problems solved by technology

However, in the prior art, intracavitary radiation therapy can cause damage to normal tissues, especially when treating vaginal tumors and uterine tumors, the protection of the bladder and rectum is not enough, and high-dose spots will appear in the rectum and bladder. Damage to otherwise healthy tissues and organs
