Puncture ovum taking device capable of conveniently detecting follicle form

Abstract

The invention relates to a puncture ovum taking device capable of conveniently detecting the follicle form. The puncture ovum taking device comprises a puncture needle, a flushing device, a negative pressure device, a test tube, a puncture needle frame and a handle part. A flushing hose is connected to the flushing device, and the test tube and the negative pressure device are connected through ahose and connected with an ovum conveying connecting tube; and a main channel in the handle part, an axis cavity in the puncture needle frame and the cavity channel of the puncture needle sequentiallycommunicate with one another. An ultrasonic probe is arranged on the outer wall of the end, connected with the puncture needle, of the puncture needle frame, and a data line connected with the ultrasonic probe extends out of the handle part and can be connected with external equipment, or the ultrasonic probe is connected with a wireless communication module so that the ultrasonic probe can be connected with external equipment in a wireless transmission mode. By means of the puncture ovum taking device, relatively clear follicle distribution images can be obtained so as to provide a good observation basis for puncture ovum taking operation, operation can be conducted smoothly and conveniently, and the ovum with good quality can be sucked.

Description

technical field [0001] The invention relates to the field of medical equipment, belongs to gynecological equipment, in particular to a puncture and egg retrieval device for detecting follicle morphology. Background technique [0002] During the egg retrieval operation, the egg retrieval needle will be inserted into the ovary through the vagina to extract the eggs from the abdomen through the ultrasound guidance. There are situations where two people are required to perform the egg retrieval operation, and the distribution of eggs in the ovary is detected through the abdomen. Through many tissues of the body, the image information reflected is more complex. [0003] Existing ovum retrieval needles are divided into single chamber ovum retrieval needles and double chamber ovum retrieval needles. [0004] In view of the fact that the puncture needle of the current double-cavity egg retrieval needle is set as an inner and outer cannula structure, the inner diameter of the outer ...

AI Technical Summary

Problems solved by technology

[0004] In view of the fact that the puncture needle of the current double-cavity egg retrieval needle is set as an inner and outer cannula structure, the inner diameter of the outer lumen is small, which results in laborious injection of flushing fluid, slow speed, and low efficiency, and makes the radial direction of the inner lumen The size is relatively smaller, and when the egg cells are sucked, the eggs will be squeezed when they flow in the cavity, and the negative pressure suction force should be relatively increased.

When the lumen of the double-lumen ovum retrieval needle is set as a B-type lumen, although the two lumens can be independent and the passability of the radial section can be improved, the entire cross-section of the puncture needle is too large for puncture surgery. It is easy to cause great damage to the patient's body and organs, increase the risk of internal bleeding, and increase the pain
