Description

Embryo transplantation probe with malformed uterine cavity detection function

Technical Field

The utility model relates to an auxiliary reproduction technical field, more specifically relate to an embryo transfer probe with dysmorphism palace chamber detection function.

Background

An assisted reproduction technology, namely an in vitro fertilization-embryo transfer technology, refers to a process that the fertilization process is completed in vitro after gametes of sterile couples are obtained, embryos are transferred into uterine cavities through an embryo transfer tool at a proper time after the embryos are fertilized and formed, and the embryos further grow and are planted on endometrium, so that pregnancy and delivery are obtained.

In the embryo transplantation process, the transplantation difficulty is usually caused by psychopsychological factors of patients or organic reasons of cervix uteri, which means that a transplantation tube cannot smoothly enter a uterine cavity and cannot be placed. The external catheter tube placing difficulty judgment standard is as follows: when the external catheter is used alone, the external catheter is inserted into the endocervical opening of the cervix for 1-2 times without penetrating the endocervical opening of the cervix. Difficult transplantation judgment standard: firstly, using an Ehrlich forceps to pull the cervix to assist the outer catheter to enter the internal opening of the cervix; ② the cervix and the uterine body are transplanted after the direction of the cervix and the uterine body is determined by the probe.

In the conventional difficult transfer procedure, after the uterus is confirmed by the probe, the probe is withdrawn from the cervix and reinserted into the embryo transfer tube. Because the probe is made of metal and has high hardness, the probe can normally and smoothly enter the uterine cavity, and when the probe is withdrawn, the problem that the outer tube of the transplanting tube cannot smoothly enter the uterine cavity still exists.

Although patent 201210379983.5 also discloses an embryo transplantation device and its application method, comprising a rigid support core and a through-going transplantation tube and a guide tube, the rigid support core is inserted into the guide tube during application, and then the guide tube is inserted into uterus for embryo transplantation, wherein the rigid support core mainly serves to reinforce the rigidity of the guide tube. Therefore, the device needs the combination of the guide tube and the support core to achieve the hardness of entering the uterus, and for a patient with uterine cavity deformity, embryo transplantation is needed, and the hardness is not good enough and cannot be used. In addition, when the support core is taken out of the guide tube, the diameter of the guide tube is changed because the guide tube is soft, and when the graft tube is inserted again, the graft tube is difficult to insert.
