Puncture needle special for aseptic ovum retrieval and aseptic ovum retrieval needle device thereof

Abstract

The invention provides a puncture needle special for aseptic ovum retrieval and an aseptic ovum retrieval needle device thereof. In the puncture needle, an ultrasonic echo region is formed at the front end of the puncture needle, and a manifold tee joint of the aseptic ovum retrieval needle is connected at the rear end of the puncture needle; and the puncture needle (1) is provided with two needle tube parts with different diameters, wherein the diameter of the front puncture part is smaller than that of the rear part. The aseptic ovum retrieval needle device comprises the puncture needle (1), a handle (2), a collection tube (3), a vacuum suction device (5), a collection bottle (15), a transfusion device (8), a transfusion bottle (9), an electromechanical interlocks (10), a constant temperature device (11) and an electromagnetic on / off device (6), wherein one end of the puncture needle is connected with the manifold tee joint, and then is communicated with the low-pressure transfusion device through the fork end of the handle; and the inner cavity of the manifold tee joint is a cavity similar to an ellipse. The aseptic ovum retrieval needle causes smaller wounds to the ovary. By the linkage of the devices, the simple, reliable and continuous operation in the process of flushing and sucking eggs can be maintained, and the aseptic ovum retrieval needle has the functions of a single-lumen needle and a double-lumen needle.

Description

technical field [0001] The present invention relates to an auxiliary medical device in the process of reproductive medical treatment. Specifically, the present invention relates to a new type of aseptic special puncture needle for egg retrieval and a sterile single-chamber egg retrieval needle device. The puncture needle (1) is a puncture needle with two sections of different diameters, and the diameter of the puncture part of the front section of the puncture needle (1) is smaller than that of the needle tube part of the rear section. The aseptic ovum retrieval needle device can adopt a needle with a smaller diameter, less trauma to the ovary, and an electromechanical linkage device, which can keep the operation of the flushing and aspiration process simple, reliable and continuous, and at the same time make the aseptic ovum retrieval The needle has the functions of a single lumen needle and a double lumen needle. Background technique [0002] In today's society, the numbe...

Problems solved by technology

[0010] The shortcoming of above-mentioned patent technology is: its needle tube diameter is made thicker, and traumatic to ovary is big, thereby has increased patient's misery

On the other hand, the reason why clinicians choose 19-23G puncture needles is to better reduce the trauma to the patient's ovary during the operation, so that the patient can recover as soon as possible, and at the same time, it increases the difficulty of clinical operation

[0016] However, due to the clinical operation requirements of the egg retrieval needle, the length of the needle tube must reach 280-380mm. In the case of stainless steel needles of this length, the sizes of 16 and 17G can still meet the clinically more ideal rigidity requirements, but the 19G The size of the puncture needle, its outer diameter is only 1.03-1.10mm. At this time, the stiffness of the puncture needle is very weak, and its clinical operation is more difficult. Moreover, when the diameter of the puncture needle is 23G, that is, its diameter is 0.6-0.673mm, in the same When the length is longer, the clinical operation is more difficult
