Ovum retrieval system suitable for one-handed operation

Abstract

The invention discloses an ovum retrieval system suitable for one-handed operation. The ovum retrieval system comprises an ovum retrieval device, a negative-pressure device, an ovum collection deviceand an optical fiber endoscopic imaging device. One end of the optical fiber endoscopic imaging device is arranged inside a puncture needle, the other end of the optical fiber endoscopic imaging device is connected with a control device by an external optical fiber, and image signals transmitted by optical fibers can be acquired and processed by a display terminal to obtain front-end images of thepuncture needle; a switch can be pushed, so that the ovum retrieval device can be communicated and connected with the negative-pressure device and the ovum collection device, the head of the punctureneedle can be in negative-pressure states, ova can be sucked, and real-time states of the ova can be transmitted to the display terminal by the optical fiber endoscopic imaging device via the controldevice. The ovum retrieval system has the advantages that a medical staff can operate an ovum retrieval needle with the single right hand in operation procedures, and accordingly puncture and ovum retrieval actions can be completely carried out; the medical staff can exactly operate an ultrasonic guide probe with the liberated left hand, accordingly, single-person left and right hand coordinationwork can be implemented, and the problem of disharmonious and asynchronous multi-person operation can be solved.

Description

technical field [0001] The invention relates to an egg retrieval system suitable for one-handed operation, which belongs to the technical field of medical equipment. Background technique [0002] In today's society, the number of infertile patients is increasing day by day due to the acceleration of the pace of work and the increasing pressure of job competition, as well as the combined influence of various other factors and the patients' own reasons. With the rapid development of assisted reproductive technology, test-tube babies are increasingly favored by many infertile couples with high-end technical support and rigorous scientific procedures. Higher requirements, the current common method is to use a single-use egg retrieval needle to puncture the ovary into the ovary to extract eggs under the guidance of ultrasound. Injury bleeding, postoperative abdominal pain and secondary pelvic infection. [0003] The existing egg retrieval device cannot be used for one-handed op...

Problems solved by technology

With the rapid development of assisted reproductive technology, test-tube babies are increasingly favored by many infertile couples with high-end technical support and rigorous scientific procedures. Higher requirements, the current common method is to use a single-use egg retrieval needle to puncture the ovary into the ovary to extract eggs under the guidance of ultrasound. Injury bleeding, postoperative abdominal pain and secondary pelvic infection

[0003] The existing egg retrieval device cannot be used for one-handed operation. In the actual operation process, several doctors usually need to cooperate to complete it. During the egg retrieval process, it is necessary to cooperate with the vaginal ultrasound detector to see the position of the needle tip and follicles. The existing The medical endoscopic probe is too bulky to be used for egg retrieval, and the existing egg collectors for egg retrieval have poor thermal insulation effect and are prone to uneven heating, which will have adverse effects on the eggs flowing through the puncture needle and the hose
