Description
Technical Field
The disclosure relates to the field of medical assisted reproduction teaching training, in particular to an embryo transplantation teaching system.
Background
Along with the social development, the change of living habits and the change of birth policies, the fertility of human beings shows a remarkable decline trend in the world, the international health organization reports that the infertility rate is up to 15 percent, and the infertility is combined with cardiovascular diseases and malignant tumors to be three diseases affecting the health of human beings. The IVF-ET (in vitro fertilization-embryo transfer) technology has become the treatment choice for more and more barrenness couples, and the improvement of the treatment efficiency, namely the pregnancy rate, is the focus of common attention of doctors and patients.
Embryo transfer is a process of returning embryos cultured in vitro into a mother uterine cavity, is an important link for determining the success or failure of IVF-ET, and the operation process should avoid damaging endometrium and inducing uterine contraction as much as possible, reduce the time of exposing the embryos in vitro and place the embryos in the optimal implantation area in the uterine cavity. In the operation, due to inexperience and insufficient experience, a clinician may operate a manipulation ineffectively, which may cause damage to cervix and endometrium, hemorrhage and uterine contraction, and the tube placement position is not ideal, and a laboratory embryologist may have the risk of ectopic pregnancy increased by too hard pushing an embryo, or the embryo may be retained in a transplantation tube and failed to transplant due to too slow pushing; and the embryo transplantation operation is more difficult for patients with abnormal uterus and cervix positions. Therefore, even if there is a high quality embryo, if there is a defect in the embryo transfer technology, the desired pregnancy rate cannot be achieved, and sufficient training should be completed before performing the clinical operation of embryo transfer. However, at present, clinicians and embryologists often conduct exploration operation directly in the bodies of infertile patients after on-site demonstration by teachers, the process is uncertain in a 'blind' (unable to look directly), and advance teaching cannot be conducted on the situation of difficulty in transplantation. Therefore, there is an urgent need for a visual embryo transfer teaching system, which enables clinicians and embryologists to master and skillfully apply embryo transfer, and to repeatedly try and learn in advance for the situation of difficult transfer due to cervical stenosis, abnormal uterine position, etc., thereby increasing the pregnancy rate of patients after transfer.
