Description

A kind of transuterine supersonic diagnosis of oviduct instrument and transducer

Technical field

This utility model relates to fallopian tube diagnostic apparatus, particularly the transuterine supersonic diagnosis of oviduct instrument of one and transducer.

Background technology

Salpingemphraxis is the main cause of disease causing female acyesis, accounts for 25% to 35%.Fallopian tube connects the channel between ovary and uterus, served as defeated ovum, storage ovum, semen deposition, provides the place of sperm ovum binding, transported germ cell to endometrial function.If fallopian tube blocks, will a series of processes of becoming pregnant such as sperm ovum binding be hindered, thus cause female acyesis.Fallopian tube is positioned at both sides, uterus, and the fallopian tube of every side has two openings, and the inner is opened on cavity of uterus and is connected with the laterior horn of fundus of uterus, and outer end opening is positioned at the top of ovary in peritoneal cavity.Whole fallopian tube is the tubular structure of elongated complications, and total length is about 70-130 millimeter, diameter about 5 millimeters.Cause the reason of salpingemphraxis mainly to be caused by inflammation, tunica mucosa tubae uterinae generation inflammatory changes, and uterine tubal epithelium generation degeneration or fall in flakes, cause tunica mucosa tubae uterinae adhesion, then blocks fallopian tube tube chamber or umbrella portion.

For the committed step that oviducal diagnosis is the infertility that treatment salpingemphraxis and then treatment cause thus.Can carry out affecting the technology learning diagnosis to salpingemphraxis at present to have: peritoneoscope, hysteroscope and coaxial falloposcopy.

Peritoneoscope is a kind of endoscope stretching into abdominal cavity.Open an aperture at abdominal part during operation, lens of laparoscope is inserted intraperitoneal, observe pelvic cavity and Intraabdominal tissue and internal organs situation by the minisize pick-up head of front end, ovary and oviducal overall structure and surrounding tissue can be seen clearly.But this technology cannot observe structure and the pathological changes of fallopian tube inside, degree and the position of salpingemphraxis cannot be evaluated.

Hysteroscope is that one stretches into intrauterine endoscope.During operation, hysteroscope transcervical is stretched into uterus, observe intrauterine situation by the minisize pick-up head of front end.This technology can observe fallopian tube opening in uterus, but cannot stretch into fallopian tube observation fallopian tube internal structure and congestion situations.

Coaxial falloposcopy is that one stretches into oviducal endoscope.It is made up of a soft imaging fibre, fallopian tube can be stretched into optical imagery is carried out to whole fallopian tube lumen internal structure, congestion situations, but visual field is little, imaging resolution low (millimeter rank), and only can carry out imaging to tissue surface, can not tissues observed Deep Lesions.

All there is certain shortcoming in existing three kinds of technology, peritoneoscope and hysteroscope only can be observed from oviducal outside, although coaxial falloposcopy can be observed oviducal inside, it only can carry out imaging to tissue surface, can not tissues observed Deep Lesions.Therefore, current fallopian tube diagnostic techniques can not carry out, effectively detecting to fallopian tube comprehensively.
