Description
Technical Field
The utility model belongs to the technical field of the medical instrument technique and specifically relates to a multi-functional compound ovum ware of getting.
Background
Generally, the ovum taking needle has a single-cavity ovum taking needle and a double-cavity ovum taking needle in the traditional medicine, and the two kinds of needles have different needle numbers and structures.
The double-cavity ovum taking needle has the needle wall characteristic with the same performance as the single-cavity ovum taking needle, adopts the needle number to distinguish the number, the needle point structure is A type or B type, the side wall of the ovum suction cavity is provided with a flushing cavity with the diameter of 0.3mm, the ovum suction cavity and the flushing in the ovary can simultaneously carry out the ovum flushing and ovum suction work, the flushing cavity structure with the unique design can obtain the maximum ovum sprinkling rate, the enhanced response head can improve the visual effect under the B-ultrasonic.
Through experimental comparison research, the following results are found: the single-cavity and double-cavity ovum taking needles have no statistical difference in the fertilization rate and the good blastocyst rate. Although the double-cavity ovum taking needle has the advantage of high ovum taking rate, the ratio of the used analgesic after the operation is obviously higher than that of the single-cavity ovum taking needle, which indicates that the discomfort after the operation of a client can be reduced by using the single-cavity ovum taking needle for the operation. In general, in the case of taking an ovum with a small number of follicles (the number of the ovum to be taken is less than 10), a double-lumen ovum-taking needle having an advantage of a high ovum-taking rate is suitably used, and in the case of taking an ovum with a large number of follicles (the number of the ovum to be taken is more than 10), a single-lumen ovum-taking needle capable of effectively reducing the occurrence probability of postoperative discomfort is suitably used.
Although the double-chamber egg-taking needle group had a higher egg-taking rate than the single-chamber egg-taking needle group, there was no significant difference in the average number of eggs taken in the two groups, which is contradictory. Although no direct evidence shows that the inference can be that the difference between the ovum-taking rate and the good embryo rate is caused by the fact that the diameter of the needle head and the flushing of a culture solution exists, in the aspect of the diameter of the needle head, a thinner single-cavity ovum-taking needle is not easy to suck non-loose follicle tissues, the non-loose follicle tissues are generally eggs with poor quality, and the average ovum quality obtained by the single-cavity ovum-taking needle is supposed to be very good, so that the good embryo rate and the good blastocyst rate are increased; in the aspect of culture solution flushing, the double-cavity ovum-taking needle can repeatedly flush the culture solution, so that the loose follicular tissues are easier to aspirate, the ovum-taking rate is high, but the embryo rate and the blastocyst rate are low, and the situations need further research.
The prior double-cavity ovum taking device has the defects that:
1. the outer pipe cavity of the inner and outer sleeve double-cavities has small inner diameter of the cavity, is labor-consuming when injecting flushing liquid, and has low speed and low efficiency.
2. The inner cavity of the double cavities of the inner sleeve and the outer sleeve has small inner diameter and can extrude eggs.
3. Although two lumens of the double-lumen B-shaped lumen are relatively independent, the section of the main tube is overlarge, the span of the oviduct in the radial direction is large, the organs punctured by the abdominal cavity of a patient are greatly injured, the internal bleeding probability is high, healing is difficult, and the risk is relatively high.
How to design and manufacture a device which has the advantages of both the single-cavity ovum-taking needle and the double-cavity ovum-taking needle in the selection of the single-cavity ovum-taking needle and the double-cavity ovum-taking needle is a more important subject to be solved in modern medicine.
