Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a transabdominal puncture egg retrieval component for assisted reproduction. Background Art

[0002] At present, assisted reproductive egg retrieval is performed through vaginal puncture under the guidance of vaginal B-ultrasound. In this process, there is a special puncture stand for the B-ultrasound probe, which can fix the scanning surface of the B-ultrasound probe directly to the target ovary. At the same time, the puncture stand also has a needle guide bracket for the egg retrieval needle, so that the puncture needle can maintain the same direction as the B-ultrasound scanning surface and point clearly.

[0003] However, clinically, there are some patients whose ovaries are located very high due to pelvic adhesions, which cannot be reached by the vaginal egg retrieval needle and require transabdominal puncture. The transabdominal puncture stands currently on the market are inconvenient to use and cannot effectively fix the puncture direction and guide like the vaginal puncture stand. The puncture stand has limited angle adjustment directions and is not flexible enough. It is not convenient to adjust and cannot fix the ultrasound probe. During puncture, both hands are required, which is inconvenient to operate. Summary of the invention
