multi-point testicular puncture needle

Abstract

The invention relates to a multipoint testicular puncture needle. The multipoint testicular puncture needle comprises inside needle fixing sliders, outside needle fixing sliders, an inside buckle, an outside buckle, inside sliding grooves, outside sliding grooves, an inside spring, an outside spring, a control button, a protective shell, inside puncture needle bodies and outside puncture needle bodies. The multipoint testicular puncture needle has the advantages that enough tissue can be punctured through multipoint biopsy puncture for histopathological examination, testicular spermatogenic function is estimated conveniently, sperms can be found out through microscope inspect directly to be used for in-vitro fertilization during the 'test-tube baby' process, damage to the tissue is quite small, and the multipoint testicular puncture needle, a novel puncture instrument, is convenient in operation, good in safety and broad in clinical application prospect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multi-point testicular puncture needle. Background technique [0002] According to the statistics of the World Health Organization (WHO), about 10-15% of couples of childbearing age in the world have infertility problems, and male factors account for about half of the infertility. In male infertility, azoospermia is undoubtedly the most serious problem. In the diagnosis and treatment of azoospermia, testicular puncture or testicular biopsy plays a vital role in the diagnosis, classification and decision-making of the next treatment plan for azoospermia. [0003] Testicular puncture is a new technology developed in recent years. With the rapid development of human assisted reproductive technology in infertility treatment, especially intraoocyte single sperm injection requires sperm extraction through testicular puncture or evaluation of testicular spermatogenic func...

AI Technical Summary

Problems solved by technology

This equipment has the following technical defects: in the case of unsatisfactory extraction of living testicular tissue, it is necessary to puncture the patient's testis again or even multiple times until the ideal living testicular tissue is obtained, which is extremely painful for the patient and also increases patient infection. chance of

But regarding a kind of multi-point biopsy that can puncture enough tissue for direct microscopic examination to find out the sperm needed on the day of egg retrieval in the "test-tube baby" in vitro fertilization process, the damage to the tissue is very small, and it can be used for tissue diseases Physical examination is convenient for evaluating the spermatogenesis function of the testis, and there is no corresponding disclosure of the convenient and safe technical solution

[0010] To sum up, there is a need for a method that can puncture enough tissue through multi-point biopsy, which can be used for histopathological examination on the one hand to facilitate the evaluation of testicular spermatogenic function, and on the other hand can also be used for direct microscopic examination to find spermatozoa. For in vitro fertilization in the process of "test tube baby", the multi-point testicular puncture needle is easy to operate and safe, but there is no report about the multi-point testicular puncture needle
