tubal sterilization via uterine occlusion

Transuteroscopic obstruction of the tubal sterilization is through the uterine cavity corner into the fallopian tube into the blocking drug, so that the fallopian tube blockage to achieve sterilization purposes. Curing disease: Indication Transuteroscopic obstruction of the tubal sterilization with general sterilization, double abdominal or vaginal surgery have concerns about voluntary requirements for the implementation of occlusion. Preoperative preparation 1. Equipment and drug preparation (1) Instruments: General instruments and dressings are placed with the intrauterine device. The outer sleeve is a stainless steel tube that can be bent freely. The inner diameter is 2.5mm and the length is 22cm. The sleeve head is equipped with a horn rubber head. The rubber head can be cut 1cm at the end of the outer tube by the end of the small urinary catheter. In addition, two polyethylene plastic pipes are inner casing inner diameter 1.0mm, outer diameter 1.5mm, length 30.0cm, and its volume is 0.3ml. Depth; tuberculin test with 1 ml syringe and 5 ml syringe each. (2) Drug: compound phenol paste, its formula: phenol 30%, A flat 35%, biliary acid 35%, which phenol acts as a corrosive effect, can make the fallopian tube adhesion. A flattening hyperplasia promotes the formation of granulation tissue, which in turn fibrosis causes the lumen to occlude. Normal saline for injection. 2, the same vaginal sterilization. 3, the inner and outer casing and cannula should be immersed in the disinfectant for more than 1/2h. 4. The compound phenol paste needs to be heated at 70 ° C in water. 5, oral or intramuscular injection of atropine 0.5mg half an hour before surgery. 6. Empty the bladder. 7, routinely flush the vulva and vagina. Surgical procedure 1, put into the vaginal device, routine disinfection of the vagina, cervix, cervical canal, with the cervical pliers to clamp the anterior lip of the cervix. 2. The probe measures the depth of the uterine cavity, the degree of cervical dilatation, the shape of the uterine cavity, and the direction of the uterine angle to select a properly curved catheter. 3. Insert the plastic cannula into the catheter to understand the relationship between the cannula scale and the catheter so that the depth of the cannula is clearly visible during operation. 4. Gently put the outer cannula and cannula into the uterine cavity (the plastic cannula does not exceed the catheter head), slide into the uterine horn after reaching the bottom of the palace, and feel whether the rubber head is in the same direction as the uterine angle. The tube was injected with 8 ml of normal saline. When there was no resistance and no outflow when injecting physiological saline, it was confirmed that the catheter head was aligned with the uterine horn, and then the cannula was gently inserted into about 0.5 cm. After the saline was injected, 1 ml of air was injected, and then Inject compound phenol paste 0.1-0.15 ml.
