[Release: Webmaster] [2015-8-13] [Close]

  HIFU 治疗原理: First, the principle of HIFU treatment:

     Utilizing the characteristics of ultrasound penetrability and focusability in biological tissues, focusing lower-intensity ultrasound in vitro into a target area in vivo, forming a focal area where high-intensity ultrasound converges, and high-intensity ultrasound-produced organism The scientific effect (thermal effect, mechanical effect, cavitation effect) caused coagulative necrosis of the tissue cells in the focal zone, but there was no significant damage to the tissues outside the focus.

HIFU 治疗 HIFU treatment of uterine fibroids

HIFU 治疗的非适应症 ( 技术上的非适应症 ) 1. Non-indications for HIFU treatment ( technical non-indications ) :     

  治疗焦距不够者,由于瘤体位置的关系,治疗的焦点达不到或者超过瘤体者; (1) If the focal length of the treatment is insufficient, the focus of the treatment cannot reach or exceed the tumor due to the location of the tumor;

  声通道不够者,声通道被遮挡 1/3 或者以上者不能治疗。 (2) Insufficient acoustic channels, those whose acoustic channels are blocked by 1/3 or more cannot be treated. The pubic symphysis or the intestine are the main obstructions to the sound channel; usually cervical fibroids are more common.

4 )肠道准备:治疗前 3 天开始进无渣饮食,治疗 前一天导泻、清洁灌肠。 ( 4 ) Intestinal preparation: Start a slag-free diet 3 days before treatment , and reduce diarrhea and clean enema one day before treatment .

HIFU 治疗术后处理 4. Postoperative management of HIFU treatment

1 )治疗后观察生命体症 2 小时;术后第二天可恢复正常生活,一周内需要避免重体力活动; ( 1 ) Observe vital signs for 2 hours after treatment ; normal life can be resumed the next day after surgery, and heavy physical activity needs to be avoided within one week;

2 )冰生理盐水 500ml 膀胱灌注, 2 小时后拔出尿管。 ( 2 ) 500ml bladder perfusion with ice-cold saline , and the urinary tube was pulled out after 2 hours.

3 )饮食:治疗后 2 小时后可进流质,之后根据患者情况,逐步恢复正常饮食; ( 3 ) Diet: fluid can be entered 2 hours after treatment , and then gradually return to normal diet according to the patient's condition;

5 )生殖避孕方案:一月后可同房,一年内工具避孕; ( 5 ) Reproductive contraceptive program: one month after intercourse, contraceptive use within one year;

HIFU 治疗子宫肌瘤的优点 5. Advantages of HIFU in treating uterine fibroids

1 )不开刀、不流血、不输血,病人痛苦小。 ( 1 ) No pain, no bleeding, no blood transfusion.

2 )无需用药,术后恢复快,术后当天就可以下床活动,部分病人可以门诊治疗。 ( 2 ) No medication is needed, and the postoperative recovery is fast. You can get out of bed on the same day after the operation, and some patients can be treated out-patient.
