Description

Ovarian injection device and device for diagnosis, prevention or treatment of ovarian disease

technical field

The utility model belongs to the field of medical devices, in particular to an ovarian injection device, and also to a device for diagnosing, preventing or treating ovarian diseases.

Background technique

Ovarian puncture is a technique of inserting a needle into the ovary to extract secretions, injecting gas or contrast agent into the ovary for examination, or injecting drugs into the ovary. Ovarian puncture is a commonly used clinical technique for the diagnosis and treatment of ovarian diseases. It is usually performed through the posterior fornix of the vagina under the guidance of B-ultrasound. At present, ovarian puncture needles are divided into single-lumen puncture needles and double-lumen puncture needles. Among them, the single-lumen puncture needle basically only has the suction function, and does not have the injection function; the needle of the double-lumen puncture needle has a double-lumen structure, one lumen is used for suctioning liquid, and the other lumen is used for injecting liquid.

Premature ovarian insufficiency (POI) disease is currently mainly treated by injecting stem cells into the ovary. However, because the ovarian volume of POI patients is very small, and the outer diameter of the existing double-lumen puncture needle is relatively large, it is not suitable for ovarian injection in POI patients; It is not suitable for injecting surgery into the smaller ovaries of POI patients.

A device suitable for injecting surgery into the smaller ovaries of POI patients is currently under investigation.
