Abstract
The utility model discloses an interstitial portion guide pipe, comprising a conical end head (1) and a flexible pipe body (2), wherein one end of the conical end head is provided with an opening and the other end of the conical end head is connected with the flexible pipe body; the tail part of the flexible pipe body is sheathed with a soft plug (5) and a joint (3) in sequence; and the joint is externally sheathed with a joint cap (4), the inner side of which is provided with threads. Since the end part is designed into a conical shape, the interstitial portion guide pipe is convenient for forward propelling in a narrow fallopian tube, and simultaneously also plays a reasonable role in leakage guide. Therefore, the utility model can be helpful to propelling interstitial portion guide pipe in the fallopian tube, reduce sensitive stimulation to the tube wall, and is beneficial to reducing discomfort of a patient and leading operation to be conducted smoothly.
Description
Technical field
This utility model relates to a kind of gynecological medical apparatus and instruments, is the operating equipment that matter portion dredged and carried contrast agent and visual probe between suitable specially women's fallopian tube, with the supporting use of uterine cavity somascope.
Background technology
Fallopian tube in the female sex organ is a pair of elongated pipe, and this fallopian tube can be divided into from inside to outside: gorge, ampulla and funnel.Fallopian tube is positioned at the both sides of fundus of uterus, and in the upper limb of mesodesma, its inner links to each other with the laterior horn of fundus of uterus, and the outer end arrives the top of ovary, free intraperitoneal.Every oviductus lateralis has two openings, two sides about branch.
Wherein: portion's interstitial part of uterine tube is inwardly to run through a section of Uterus wall from the uterus laterior horn between oviducal uterine part or Uterus wall, is about 1cm, and its inner in cavity of uterus, is called the about 0.1cm of uterine orifice of uterine tube diameter with thin choana.Isthmus of uterine tube is to stretch out from uterus laterior horn level, reaches near a section the ovary lower end, accounts for 1/3 of fallopian tube total length, in connect interstitial part of uterine tube, connect ampulla of uterine tube outward.This one is short and thin straight, and the wall thickness chamber is narrow.Salpingitis inflammation repeatedly easily causes isthmus to stop up and causes infertilely, and in clinical program fertility operation, isthmus of uterine tube is the first-selected position of tubal ligation and the bonding art of silica gel.The ampulla of uterine tube ampulla of uterine tube continues the outer end in isthmus of uterine tube, is that fallopian tube is the longest, caliber is the thickest one section.Account for 2/3 of fallopian tube total length.
Therefore just because of oviducal this special physiological structure, in gynecologial examination, often get involved, but should not check discovery because of the narrow of pipeline because of the up infection in vagina, uterus or the inflammation of peritoneal cavity.B ultrasonic and X-ray examination can not judge to organize whether pathological changes or which kind of pathological changes take place.
Cause infertile or ectopic pregnancy owing to salpingitis tubal easily causes isthmus to stop up simultaneously.For carry out the salpingitis tubal inspection and cure since salpingitis cause that the isthmus obstruction causes infertile or ectopic pregnancy, in present gynecologial examination, all use interstitial catheter to carry out the inspection and the treatment of above-mentioned affected area.Interstitial catheter enters fallopian tube from hysteroscope or laparoscopically passage.But, and, be unwell in narrow especially fallopian tube and move because this conduit adopts the diameter that equates before and after the whole conduit because there is structural limitation in the interstitial catheter that uses now.
Dredging oviduct available physical method realizes, uses steel wire to dredge usually.The dangerous property of such method needs to cooperate camera lens or probe to observe.
Because the design of afterbody joint is unreasonable, be difficult to connect transfusion in addition.Therefore, how existing interstitial catheter is carried out necessary architecture advances, make it can be conveniently used in gynecologial examination, alleviate the misery of patient when using, reach the inspection therapeutic purposes simultaneously.
The utility model content
This utility model aims to provide the more comprehensive interstitial catheter of a kind of utilitarian function, can satisfy the purpose of fallopian tube inspection, treatment, also can alleviate patient's misery simultaneously.
This interstitial catheter, its structure comprises cone-shaped end and flexible pipe body; The first end opening of tapering point, the other end is connected with flexible pipe body; Sheathed successively cork of the afterbody of flexible pipe body and joint; The outside sheathed connector cover medicated cap of described joint, joint block inboard is provided with screw thread.Such design, available threaded joint block connect and fixing fluid delivery apparatus, make operation more simple and reliable.Cork is used for interstitial catheter is fixed in hysteroscope or the laparoscopically passage.
The cone-apex angle of described cone-shaped end is 5～30 ℃, and the length of cone-shaped end is 2～8mm.
Described cone-shaped end and the flexible pipe body shape that is in line is connected; Perhaps, described cone-shaped end becomes 2～15 ℃ of arcs to be connected with flexible pipe body.
Described cone-shaped end inside is provided with fluoresent coating.Fluoresent coating can be used for improving the brightness in the visual field.
The material of described cone-shaped end and flexible pipe body is PVC, PE or PET.
Described joint is connected with the integrated molding of flexible pipe body.
This interstitial catheter according to above technical scheme proposition, not only can reach the existing function of existing known matter conduit, and because the end is designed to tapered shape, both be convenient in narrow fallopian tube, advance forward, also play simultaneously and reasonably lead leakage effect; Therefore can help body in intratubal propelling, reduce, help alleviating patient's discomfort and carrying out smoothly of operation because of tube wall sensitivity is stimulated.

The specific embodiment
Embodiment 1
Interstitial catheter as shown in Figure 1, its structure comprise cone-shaped end 1 and flexible pipe body 2; The first end opening of tapering point, the other end is connected with flexible pipe body; Sheathed successively cork 5 of the afterbody of flexible pipe body and joint 4; The outside sheathed connector cover medicated cap 4 of joint, joint block inboard is provided with screw thread.
As shown in Figure 2, cone-shaped end 1 and 2 linearly connections of flexible pipe body (same central shaft), there is fluoresent coating 101 inboard of cone-shaped end.Fluoresent coating can improve the brightness in the visual field.
The cone-apex angle α of cone-shaped end is 5～30 ℃.The material of cone-shaped end and flexible pipe body is PVC.Described joint is connected with the integrated molding of body.
Utilize screwed joint block to connect during operation and fixing fluid delivery apparatus, make operation more simple and reliable.And utilize cork that interstitial catheter is fixed in hysteroscope or the laparoscopically passage.
For the arc-shaped bend shape is connected, as shown in Figure 3, all the other are with embodiment 1 between cone-shaped end 1 and the flexible pipe body 2.Its role is to, make conduit have certain radian, help moving ahead, reduce scouring abrasion the fallopian tube inwall the intratubal of arc-shaped bend.And making it adapt to oviducal flexibility, the flexibility of only utilizing flexible pipe body itself among the embodiment 1 moves ahead.
