Three mirrors and one trace technology is a diagnostic and therapeutic standard formulated by WHO, which integrates the advantages of high-tech electronic display system, high-tech equipment and traditional surgery into one minimally invasive frontier technology for infertility. Through the combined use of salpingoscope, hysteroscope, "three mirrors" of laparoscopy and "one trace" of Cook's guide wire system, the diseases in ovary, uterine cavity, abdominal cavity and fallopian tube cavity can be accurately detected at one time, which can comprehensively solve the problems of uterus, ovarian pelvic cavity, hydrosalpinx, adhesion and obstruction at the same time, and improve the safety of interventional dredging diagnosis and treatment of infertility and the pregnancy rate of infertility patients. It is the highest-end infertility diagnosis and treatment technology recognized by the international medical community. According to statistics, the success rate of combined operation of three mirrors and one silk in treating infertility is as high as 98%.

The "three mirrors" are hysteroscopy, laparoscopy and salpingoscopy, and the "one trace" is the fine cooking guide wire of fallopian tube.

Hysteroscopy: You can know the situation inside the uterus and whether there are polyps and adhesions in the uterine horn and fallopian tube interstitial part.

Laparoscopy: You can know the specific situation in the abdominal cavity, the tissue structure around the fallopian tube and whether there is adhesion.

Tuboscopy: It can check the normal epithelium and abnormal lesions of fallopian tubes and identify the causes of proximal tubal obstruction.

"A trace" is a technique used to dredge fallopian tubes.
