Description
Technical Field
The application relates to the field of medical instruments, in particular to an intrarectal ultrasonic blocker.
Background
Focused Ultrasound (HIFU) is an in vitro high-intensity ultrasonic wave, which is focused into a point in vivo by a special device, and generates high temperature at the focal point, so that the target tissue can kill focus cells and tissues, thereby treating diseases, and the focused ultrasound (HIFU) is currently used as an emerging noninvasive treatment mode for liver cancer, breast cancer, prostate and other diseases, and is gradually accepted by vast doctors and patients, especially has wider application in gynaecology and obstetrics, such as treating hysteromyoma, adenomyosis, incision pregnancy and the like.
However, in the process of using HIFU to treat gynaecology and obstetrics diseases, the lumbar vertebra, the sacral coccyx, the buttocks, the outer side of the thigh, the popliteal fossa and other parts of the patient can generate acid swelling, numbness or weakness of the lower limb, even dyskinesia, which are adverse reactions caused by pressure, scattering and reflection of focused ultrasonic waves, so that the risk of side injury of the patient caused by HIFU in clinical use is increased, and in order to reduce the probability of injury of the patient, the existing problems are needed to be solved.
The acid swelling numbness occurs at the positions of the lumbosacral vertebrae, buttocks, the outer sides of thighs, the popliteal fossa and the like of the patient mainly because a backward pressure is formed after the ultrasonic wave is focused, and meanwhile, a part of high-intensity ultrasonic waves can spread to the rear of a focus, scattering, reflection and other effects occur among tissues and organs, the scattered and reflected ultrasonic waves can possibly cause secondary focusing of sound waves, and heat generated by focusing causes damage of other normal tissues and organs (namely, the back field effect of HIFU).
The back field effect of HIFU seriously affects the safety of treatment, and various adverse reactions are simultaneously combined, so that clinicians are continuously searching methods for reducing the back field effect of HIFU, such as reducing treatment power, changing the incidence angle of sound waves, inserting a condom filled with liquid into rectum, and the like. Compared with other methods, the effect of 'inserting a condom filled with liquid into the rectum' is superior to that of other methods, the method has obvious defects in long-term clinical use, is difficult to manufacture, is difficult to inject liquid into the condom, is difficult to control the amount of the injected liquid, cannot contain gas in the condom, and needs repeated inspection and trial; after water injection, the condom is not easy to pass through anus; under the high-power condition, the saccular structure manufactured by the condom still cannot block the backward propagation of ultrasonic waves to stimulate sacral plexus; the cooling effect is achieved in a short time, and under the condition of long treatment time, liquid in the bag cannot be exchanged with the outside, so that the cooling effect cannot be achieved.
