Rectally-inserted balloon device capable of relieving ultrasonic treatment side reactions

Abstract

The invention discloses a rectally-inserted balloon device capable of relieving ultrasonic treatment side reaction, which comprises a main catheter with an internal channel and a water bag covering the periphery of the main catheter and used for extruding a rectum wall, and is characterized in that the head end surface of the main catheter is spherical bulging; an inner port communicated with theinner channel and an outer port communicated with the outside are respectively formed in the main catheter, and a water delivery catheter is connected outside the water bag; the water bag can expand to the required size after being filled with required liquid, the rectum can be pressed to stop bleeding, the distance between the focus and the buttocks, sacrum and caudal bones can be increased during high-intensity focused ultrasound treatment of uterine diseases, and the water bag also has the effects of absorbing ultrasonic energy and lowering the temperature. Therefore, stimulation of buttocks, sacrum and caudal bones caused by high-intensity focused ultrasound treatment of uterine diseases is relieved, and pain or discomfort is reduced.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a transrectal insertion balloon device for alleviating side effects of ultrasonic therapy. Background technique [0002] When high-intensity focused ultrasound is used to treat uterine diseases, patients often have pain or soreness in the buttocks, sacrum, and coccyx. Rely on narcotic drugs to control the above symptoms. Symptoms become more pronounced and last hours to days after treatment ends, as the narcotic drug is stopped. [0003] In order to solve the above problems, clinicians try to insert an ordinary urinary catheter into the patient's rectum, and inject water into the balloon to increase the distance between the uterus and the buttocks, sacrum, and coccyx, so that the patient's symptoms are significantly relieved, and the dosage of anesthetic drugs is reduced. , thus speeding up the treatment. However, the current common urinary catheter is designed for the structure o...

AI Technical Summary

Problems solved by technology

However, the current common urinary catheter is designed for the structure of the urethra, and it is difficult to operate when it is inserted into the rectum. figure 1 As shown, it is easy to twist in the inner opening of the anus, and in many cases cannot be inserted to the required depth of the rectum, and the water bladder is too small, the degree of expansion is not enough, and it is easy to burst

[0004] At present, there is a lack of a capsule catheter inserted into the rectum in the treatment of uterine diseases with high-intensity focused ultrasound
