Description

Puncture ovum device of getting
Technical Field
The invention relates to the technical field of medical instruments, in particular to a puncture ovum taking device.
Background
Along with the continuous acceleration of the life and work rhythm of people in the current society, the pressure of all aspects of the people is increased, and the degree of pollution to the living environment is increased along with the bad eating habits and work and rest habits of people, so that the number of sterile patients is increased rapidly. In order to solve the problem of infertility, assisted reproduction technology is proposed, and test-tube infants are increasingly favored by numerous infertility couples.
The current common method for the ovum taking operation is to adopt an ovum taking needle to enter the ovary for sucking ovum through vaginal puncture under the guidance of ultrasonic wave. The egg taking needle is provided with a single-cavity egg taking needle and a double-cavity egg taking needle in traditional medicine, the needle numbers and the structures of the single-cavity egg taking needle and the double-cavity egg taking needle are different, but the double-cavity egg taking needle has the needle wall characteristics with the same performance as the single-cavity egg taking needle, the needle point structure is of an A type or a B type, a flushing cavity with the diameter of 0.3mm is arranged on the side wall of the egg sucking cavity, egg flushing and egg sucking operations can be carried out in the ovary through the egg sucking cavity and flushing, the maximum egg sprinkling rate can be obtained through the flushing cavity structure, and the visual effect under B ultrasonic is improved.
Single-lumen aspiration needles have a better chance of embryogenesis, but finer single-lumen aspiration needles do not readily aspirate non-loose follicular tissue, often of poor quality eggs. The double-cavity egg taking needle can repeatedly wash the culture solution, so that the non-loose follicular tissue is easier to suck out, and the high egg taking rate but lower embryo rate and good blastula rate are also caused.
The existing double-cavity ovum taking needle has the problems that the puncture needle is of an inner and outer sleeve structure, the inner diameter of an outer cavity is relatively laborious when pushing and injecting flushing liquid, the speed is low, the efficiency is low, the radial size of the inner cavity is relatively small, an ovum can be extruded when flowing in a cavity channel when sucking the ovum, and the negative pressure suction force is relatively large. When the lumen of the double-cavity ovum taking needle is set to be a B-type lumen, although the trafficability of the two lumens in independent and radial cross sections is improved, the whole cross section of the puncture needle is overlarge, and great damage is caused to the body and organs of a patient, pain is increased, and internal bleeding risks are increased.
The patent aims at improving the structure of the egg taking device so as to design the egg taking device with the advantages of the single-cavity egg taking needle and the double-cavity egg taking needle.

The negative pressure device is connected with the test tube in the test tube unit through the hose, so that negative pressure can be formed in the lumen of the test tube, and then an ovum can enter from the port of the puncture needle and flow into the test tube through the lumen of the handle and the hose.
Valve body structures, such as solenoid valves, may be provided on each hose, with single-pass and/or multiple-pass solenoid valves being specifically selectable.
And a hose connected with the flushing device is connected with the handle part through a branch pipe of the composite cavity.
And in the cavity structure of the handle, an expanding cavity is formed at one end, which is away from the puncture needle, of the handle, and one end of a hose arranged between the handle and the test tube and one end of the branch pipe of the composite cavity are respectively communicated with the expanding cavity.

The other end of the capsule cavity tube extends out of the composite cavity branch tube and is connected with a suction and filling device.
The suction and inflation device can selectively inject a medium into the bag body, so that the bag body is inflated to block the communication relationship between a hose connected with the flushing device and the handle cavity (the sealing is realized by virtue of the compression relationship formed between the wall body of the bag body and the inner wall of the cavity), and the medium in the bag body is sucked out, so that the bag body is contracted to promote the hose connected with the flushing device and the handle cavity to be in communication relationship (the communication is realized by virtue of the gap formed between the wall body of the bag body and the inner wall of the cavity).
The operation of the suction and filling device is staged, when the bag body is inflated to a certain degree or contracted to a certain degree, the power part of the suction and filling device stops operating, and after the flushing or ovum fetching operation is completed in stages, the operation action opposite to the current stagnation state is performed, for example: when the state of stagnation is a state in which liquid is filled into the bag body, the operation of drawing out the liquid in the bag body is performed next time.
Under the embodiment of the patent, a section of shared cavity is formed in the handle, and an ovum needs to flow through the section of shared cavity when being guided into the test tube through the puncture needle, and simultaneously, flushing liquid also needs to flow through the section of cavity when entering the puncture needle. The section of cavity is away from the end corresponding to the puncture needle and forms an expanding cavity, the expanding cavity is used for connecting a channel for conveying eggs and a channel for inputting flushing fluid, the radial section of the cavity for conveying eggs is allowed to be matched with the radial section of the cavity of the puncture needle, the cavity for conveying eggs can be allowed to form a larger radial section, further compression/extrusion on eggs can be avoided in the egg conveying process, and the flushing cavity can be simultaneously allowed to be flushed by the larger radial section flux, so that the pressure requirement for feeding flushing fluid is reduced, the injection of the flushing fluid is labor-saving, the speed is obviously improved, and the efficiency is increased. The bag body is arranged to adjust the connection relation of each cavity channel at the mouth expanding cavity, so that on one hand, the function of controlling the on-off of a flushing fluid flow channel can be achieved, on the other hand, the size of the cavity of the mouth expanding cavity and the trend of the cavity channels can be changed, and a smooth channel structure is built for the extracted ovum to smoothly flow into a hose connected with a test tube through the mouth expanding cavity.
Therefore, the patent does not need to enlarge the lumen of the egg taking needle additionally while improving the smoothness of the egg conveying cavity and the rapidness and high efficiency of the flushing fluid cavity, and avoids the overlarge whole cross section of the puncture needle. The puncture operation does not cause great damage to the body and organs of the patient and increase pain.
