Description

Hysteroscope assisting in embryo transplantation

Technical Field

The disclosure relates to the technical field of medical treatment, in particular to a hysteroscope assisting in embryo transplantation.

Background

According to the statistical data of the world health organization, about one sixth of the breeding age of couples is combined with infertility, and the in vitro fertilization-embryo transfer technology provides hope for breeding offspring. Studies have shown that embryo transfer pregnancy success rates are largely dependent on embryo quality, endometrial receptivity, and the embryo transfer technique itself. Embryo transfer techniques, which deliver embryos to the site within the endometrium where implantation is most likely to occur with minimal trauma, are the last and most critical step in determining the success of pregnancy. However, conventional transplantation difficulties occur in about 8.4-10% of patients due to factors such as excessive uterine flexion, narrow and curved cervix, diverticular formation by caesarean section, pelvic adhesion uterine suspension, uterine fibroids and abnormal uterine cavity morphology.

The current clinical solution for patients with difficult transplantation comprises (1) abandoning transplantation in the period, correcting uterine abnormality through operation, and then considering transplantation, and the problems of long waiting time, operation risk complications and the like exist; (2) embryo transplantation under ultrasonic guidance: for patients with abnormal anatomical structures, the risk of transplantation failure still exists, the patients need to fill the bladder to obtain an ultrasonic observation window, and the probe is pressed to cause the patient discomfort to cause uterine contraction so as to reduce the success probability of transplantation; (3) transplanting by puncture of a myometrium: the puncture will cause the damage and bleeding of the myometrium, and the uncertain transplanting position reduces the success rate of pregnancy and increases the risk of ectopic pregnancy.

The hysteroscope is used as a fiber light source endoscope, is a common gynecological minimally invasive diagnosis and treatment technology for examining and treating the uterine cavity and has the advantages that the front part of the endoscope body enters the uterine cavity and has an amplification effect on the observed part, so that the abnormality and the pathological changes in the uterine cavity can be intuitively and accurately diagnosed, and the treatment is completed. Aiming at the difficult transplantation patients, the embryo can enter the uterine cavity in a noninvasive and visible way through the hysteroscope, and a proper position is selected, so that the hysteroscope for assisting embryo transplantation is urgently needed, the operation of implanting the embryo into the optimal position of the inner membrane is completed, the transplantation failure is avoided, the success rate of pregnancy is improved, and the risks of abortion and ectopic pregnancy are reduced.
