Ultrasonic wave blocker in rectum

Abstract

The invention provides an ultrasonic wave blocker in a rectum, and relates to the field of medical instruments. The ultrasonic wave blocker in the rectum comprises a water bag type bag body mechanism inserted in the rectum of a patient, one end of the water bag type bag body mechanism communicates with a main pipeline mechanism used for water inlet and outlet, the water bag type bag body mechanism is of a double-layer water bag type structure, a sound absorption type attaching plate mechanism is wrapped in a double-layer water bag of the water bag type bag body mechanism, the top of the water bag type bag body mechanism is integrally connected with a connecting type mechanism, the water bag type bag body mechanism and the main pipeline mechanism are connected in an inserted mode through the connecting type mechanism, a rubber type sealing ring is arranged at the connecting position of the connecting type mechanism and the main pipeline mechanism, and one end of the main pipeline mechanism is connected with a water injection pipeline mechanism. Water pressure and temperature in the water bag type bag body mechanism are adjusted through repeated water injection and water drainage, after use, deaerated water is drained through a water outlet pipeline mechanism, so that the problems that liquid in the bag cannot be exchanged with the outside, and cooling cannot be achieved are solved.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to an intrarectal ultrasonic blocker. Background technique [0002] Focused ultrasound (HIFU) emits high-intensity ultrasonic waves outside the body. The ultrasonic waves are focused into a point in the target tissue in the body through a special device, and high temperature is generated at the focal point, so that the target tissue can achieve the purpose of killing focus cells and tissues, thereby To treat diseases, Focused Ultrasound (HIFU) therapy is currently an emerging non-invasive treatment method, which is applied to liver cancer, breast cancer, prostate and other diseases, and has gradually been recognized by doctors and patients, especially in obstetrics and gynecology. More extensive, such as the treatment of uterine fibroids, adenomyosis, incisional pregnancy, etc. [0003] However, in the process of using HIFU to treat obstetrics and gynecology diseases, patie...

Problems solved by technology

Among them, compared with other methods, the effect of "inserting a condom filled with liquid into the rectum" is better than other methods. In long-term clinical use, its disadvantages are also obvious, and it is difficult to make. The amount of liquid is not easy to control, and there should be no gas in the condom, which requires repeated inspections and attempts; the condom is not easy to pass through the anus after water injection; under the condition of high power, the capsule structure made of the condom still cannot block the ultrasonic waves Propagate backwards to stimulate the sacral plexus; it has a cooling effect in a short period of time. In the case of a long treatment time, the fluid in the capsule cannot exchange with the outside world and cannot play a role in cooling
