AI Technical Summary
Existing embryo transfer catheters cannot achieve embryo transfer when the patient's reproductive tract is abnormal, especially when the vagina or cervix is not connected to the uterine cavity, making it impossible to enter the uterine cavity through the vagina.
Design a puncture needle with a rigid needle tube. The first end face of the needle tube is inclined relative to the axis, forming a first included angle of 15° to 20°. Two bevels are provided at the needle tip to reduce deformation and improve puncture efficiency during puncture.
With its rigid needle tube and reasonable angle design, the puncture needle can effectively penetrate living organisms, such as through the abdominal skin or vagina, to enter the uterine cavity for embryo transfer, thus improving puncture efficiency.
