Double-cavity embryo transplantation tube

Abstract

The invention discloses a double-cavity embryo transfer tube. The double-cavity embryo transfer tube comprises a catheter assembly, an ingress tube assembly and a sleeve core assembly, the catheter assembly comprises a catheter base, a catheter and a supporting tube, the interior of the catheter is of a double-cavity structure, the supporting tube is arranged in a cavity with the small capacity, the cavity with the large capacity is an embryo channel, and a stainless steel wire is embedded in the supporting tube. The controllability of the catheter is improved through the supporting tube, ultrasonic visualization is achieved through the stainless steel wire and the ultrasonic developing ring at the front end of the catheter, and transplantation conditions are optimized. The ingress pipe assembly comprises an ingress pipe seat and an ingress pipe, the ingress pipe is provided with a fixing ring and a distance indication mark, and the end of the ingress pipe is further provided with a wrapping head. The front end of the ingress pipe is bent into a proper angle in advance, so that the ingress pipe conforms to the physiological structure of the human body, and the ingress pipe can be conveniently fed into the uterus. The sleeve core assembly comprises a sleeve core seat, a sleeve core pipe and a supporting wire, and the supporting wire is embedded in the sleeve core pipe. The sleeve core assembly can improve the controllability of the structure when the ingress pipe is not easy to pass through the cervix uteri, and is suitable for surgical operations under various cervix uteri conditions.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a double-cavity embryo transfer tube. Background technique [0002] In vitro fertilization combined with embryo transfer technology (also known as test tube baby) is the main method for the treatment of infertility at present. It obtains embryos through in vitro fertilization and culture of sperm and eggs, and then sends the embryos into the mother's uterus through a transfer tube. , wherein the rational design of the embryo transfer tube has an important impact on whether the embryo can be sent to the appropriate position in the uterine cavity. The embryo transfer tube in the prior art is difficult to send into the introduction tube under the condition of the cervix. For example, CN205234600U discloses A kind of embryo transfer tube is proposed, the introduction tube is straight design, it is not easy for the introduction tube to be sent into the uterus. Moreover, the head of...

[0002] In vitro fertilization combined with embryo transfer technology (also known as test tube baby) is the main method for the treatment of infertility at present. It obtains embryos through in vitro fertilization and culture of sperm and eggs, and then sends the embryos into the mother's uterus through a transfer tube. , wherein the rational design of the embryo transfer tube has an important impact on whether the embryo can be sent to the appropriate position in the uterine cavity. The embryo transfer tube in the prior art is difficult to send into the introduction tube under the condition of the cervix. For example, CN205234600U discloses A kind of embryo transfer tube, the introduction tube is straight design, it is not easy to send the tube into the uterus

Moreover, the head of the introduction tube is not specially treated, which will damage the endometrium during the introduction process

In addition, this type of embryo transfer tube has no visualization design, so the transfer process cannot be visualized by ultrasound, and the transfer point cannot be accurately observed
