Description

Puncture ovum taking device
Technical Field
The invention relates to the technical field of medical instruments, in particular to a puncture ovum taking device.
Background
In the current society, along with the continuous acceleration of the rhythm of life and work of people, the pressure on all aspects is increasingly high, in addition, the pollution degree of the living environment is gradually increased along with the unfavorable eating habits and work and rest habits of people, and the number of the patients who are not pregnant and are sterile is rapidly increased. In order to solve the problem of infertility, an assisted reproduction technology is proposed, and test tube infants are increasingly favored by numerous infertility couples.
The method generally used in the prior ovum taking operation is to adopt an ovum taking needle to penetrate into an ovary through vagina under the guidance of ultrasonic waves to suck the ovum. The ovum taking needle has a single-cavity ovum taking needle and a double-cavity ovum taking needle in the traditional medical science, the needle numbers and the structures of the two are different, but the double-cavity ovum taking needle has the needle wall characteristics with the same performance as the single-cavity ovum taking needle, the needle point structure is A type or B type, a flushing cavity with the diameter of 0.3mm is arranged on the side wall of the ovum suction cavity, the ovum flushing and the ovum sucking operations can be carried out in the ovum suction cavity and the flushing in the ovary, the structure of the flushing cavity can obtain the maximum ovum sprinkling rate, and the visual effect under the B-ultrasonography is improved.
The single-lumen aspiration needle has better chance of embryo formation, but the thinner single-lumen aspiration needle is not easy to aspirate the loose follicular tissue, which is usually the ovum of poor quality. Because the double-cavity ovum pickup needle can repeatedly wash the culture solution, the loose follicular tissue is easier to be sucked out, and the high ovum pickup rate, the low embryo pickup rate and the good blastocyst rate are also caused.
The ovum needle is got to current double-chambered, and the pjncture needle is interior outer sleeve structure, and the internal diameter of outer lumen is less when injecting the flush fluid more hard, and speed is slow, inefficiency, makes the radial dimension of interior lumen diminish relatively moreover, can make the ovum receive the extrusion when the intracavity flows when absorbing the ovum, and the negative pressure suction power will transfer a lot relatively. When the lumen of the double-lumen ovum taking needle is set as the B-shaped lumen, although the independent and radial section trafficability of the two lumens can be improved, the whole cross section of the puncture needle is overlarge, the puncture operation can cause great damage to the body and organs of a patient, the pain is increased, the internal bleeding risk is increased, and other adverse effects.
The purpose of this patent lies in improving the structure of getting the ovum device to design one kind and have the ovum device of getting of single chamber ovum needle and the double chamber ovum needle advantage concurrently.

In addition, the terms "upper", "lower", "front", "rear" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the relative positions may be changed or adjusted without substantial technical changes.
The puncture ovum taking device as shown in fig. 1 to fig. 3 comprises a puncture needle 2 which is connected with one end of a handle part 1 and is communicated with a main cavity 11 arranged in the handle part 1, an ovum conveying hose 41 and a compound cavity branch pipe 6 which are connected with the other end of the handle part 1 and are respectively communicated with the main cavity 11, a negative pressure device 3, a test tube 4, a flushing device 5, a suction filling device 7, a monitoring/sensing device 8 and a capsule 9. The end of the puncture needle is provided with an ultrasonic identification line 21.
The port cover of test tube 4 is equipped with the plug, and the body is arranged in test tube sleeve 42 to help test tube 4 to place on the desktop firmly with the help of test tube sleeve 42, but also can give test tube sleeve 42 the ability that provides constant temperature environment and other environmental conditions that do benefit to the ovum and survive for test tube 4.
The negative pressure device 3 is communicated with the lumen of the test tube 4 through a first hose 31. The free end of the egg-conveying hose 41 is communicated to the tube cavity of the test tube 4.
The flushing device 5 is connected with the compound cavity branch pipe 6 through a second hose 51 and can be communicated with the main cavity channel 11. In the embodiment shown in fig. 1, the operation/stop of the flushing device 5 is controlled by means of a foot switch 52.
The interior of the composite chamber branch tube 6 is formed with an axial sleeve and the inner end of the axial sleeve is formed as a tapered lumen. The lumen of the axial sleeve and the channels between the axial sleeve and the wall of the composite lumen branch tube 6 form a flushing fluid flow channel 61. Through holes 611 are distributed on the tube wall of the axial sleeve. The second hose 51 is connected to the composite chamber branch tube 6 and then communicates with the channel between the axial sleeve and the wall of the composite chamber branch tube 6, and communicates with the lumen of the axial sleeve through the through hole 611 to establish a communication relationship with the main channel 11, so that the flushing fluid can be sent into the main channel 11 through the second hose 51 and ejected from the puncture needle 2.
The capsule body 9 is arranged at the conical cavity of the axial sleeve and is connected with the suction device 7 through a capsule cavity pipe 62 arranged in the axial sleeve by a connecting branch pipe 71. The suction and filling means 7 are able to selectively inject liquid (or gas) into the capsule 9, so that the capsule 9 is inflated and blocks the communication between the axial sleeve and the main channel 11, and suck out the liquid (or gas) inside the capsule 9, so that the capsule 9 is deflated and the communication between the axial sleeve and the main channel 11 is established.
The suction device 7 comprises a tank containing liquid (or gas) and a power part (such as a lumen pump) which, in an operating state, can suck the liquid in the tank and send the liquid into the balloon 9 so that the balloon is expanded to block the tapered lumen part of the axial sleeve and block the communication with the main channel 11. In another operation state, the liquid in the capsule 9 can be pumped out to the tank, so that the capsule is shrunk and becomes small, a gap is formed between the outer wall of the capsule and the wall body of the conical cavity of the axial sleeve, and a communication relation is established between the gap and the main cavity channel 11. It can be seen that the operation of the suction device 7 is staged, when the balloon body is expanded to a certain extent or reduced to a certain extent, the power part of the suction device 7 stops operating, and after the flushing or ovum taking operation is completed in stages, the operation opposite to the current stagnation state is performed (if the current stagnation state is the state of filling liquid into the balloon body, the next operation is performed to pump out the liquid in the balloon body).
