Integrated device for scratching and sucking endometrial tissues under hysteroscope

Abstract

The invention discloses a hysteroscope endometrial tissue curettage and suction integrated device which comprises a regulation and control assembly, a tube cavity assembly, a fixing clamping sleeve, an inflation and suction pump, a fixing tube, a suction and adjustment tube, an outer tube sleeve, an air bag sleeve and a suction soft head. Secondly, the inflation and aspiration pump can inflate the outer pipe sleeve and the air bag sleeve, the air bag sleeve can expand leftwards, conversely, when the inflation and aspiration pump sucks air, the air bag sleeve can contract rightwards, and in conclusion, by means of the telescopic effect of the air bag sleeve, the air bag sleeve can stretch into the uterine cavity of a patient; finally, the suction adjusting tube can slide left and right along the interior of a fixing tube in the adjusting and controlling assembly, position adjustment is achieved, in addition, the suction adjusting tube can be connected with an external negative pressure device such as a negative pressure drainage bottle, and the purpose that hydrops in the uterine cavity of a patient is drained outwards from the suction soft head through the suction adjusting tube is achieved.

Description

Technical field [0001] The present invention relates to the field of medical devices, and in particular, to a hysteroscopic scratching suction trace endometrial tissue. Background technique [0002] Endometrial tolerance is a series of changes in a constraint that can be adhered to adhere, penetrate into an endometrium and induce an endometrium, and finally implanted an inner membrane. Good endometrial band is an important part of ensuring that pregnant eggs, fetal and placental development. The key to the success of the treatment of infertility in the treatment of infertility is the ion embryo quality and endometrial bandability. With the maturity of embryo culture and frozen thawing technology, 2 / 3 of the patient who repeated bed failure is caused by poor endometrial band, so how to increase the intimaeability and increase the clinical pregnancy rate The doctor is concerned. [0003] Endometrial scraping is to improve the local microcirculation and metabolism of the endometrium...

AI Technical Summary

Problems solved by technology

The traditional instrument of endometrial curettage is the existing probe or curette, but its clinical application has its disadvantages;

[0004] (1) Shortcomings of the existing probes: the contact area of ​​the endometrium is small, the scratching effect is weak, and the inflammatory response is poor;

[0005] (2) Shortcomings of the existing curette: the curette is a common long-handled spoon with an integrated structure of the head and the handle. Although it has a large contact area with the endometrium and a wide range of curettage, the head of the curette is damaged. The endometrium is more serious, which may cause irreversible damage to the endometrium, resulting in thin endometrium or intrauterine adhesions, which will affect the long-term pregnancy outcome

[0006] (3) Not only cannot effectively cooperate with the hysteroscope, which affects the operation, but also cannot realize the negative pressure suction of the uterine cavity fluid, which interferes with the operation field
