Problems solved by technology

[0003] Due to the narrow lumen of the fallopian tube, the precision of the operation is very high. Laparoscopic surgery has a certain effect in the treatment of pelvic adhesions and distal fallopian tube obstruction. However, adhesions and obstructions often form again after surgery, and the postoperative pregnancy rate is low. ; and hysteroscopic tubal orifice intubation for the treatment of proximal fallopian tube obstruction and partial adhesion of the fallopian tube lumen, the probability of re-adhesion after surgery is greater than that of distal fallopian tube surgery

Embodiment 1

[0023] Such as figure 1 As shown, the fallopian tube stent of this embodiment includes an elastic hollow tube body, and the elastic hollow tube body includes a straight tube section 3, a first curly section 1 arranged at the head end of the straight tube section 3 and a first curled section 1 arranged at the tail end of the straight tube section 3 Two curly paragraphs 2.

[0024] It should be pointed out that the head end of the above-mentioned straight tube section 3 refers to the end close to the umbrella of the fallopian tube when in use, that is, the end that is relatively farther away from the uterus; One end of the body, that is, the end that is relatively closer to the uterus. Unless otherwise specified, the head end and tail end of other parts are also based on this standard.

[0025] When the device is used, insert the head end of the first curly section 1 into the entrance of the interstitium of the fallopian tube by means of a hysteroscope, and then go through the...

Embodiment 2

[0031] Compared with the previous embodiment, this embodiment is generally the same, except that the structure of the straight pipe section 3 is different: the straight pipe section 3 of the previous embodiment is made of smooth sections, while the present embodiment is set on the straight pipe section 3 There are folding segments9.

[0032] Such as figure 2 As shown, specific to the folded section 9 of this embodiment, the concrete shape of its pipe wall is organ-shaped, so it is called organ-shaped folded pipe wall 10 . The accordion shape means that its folded form is similar to the bellows of an accordion, and it has multiple tooth-shaped folded structures viewed from its side section. In addition, it should be noted that the third through hole 5 can also be provided on the folded section 9 , but its unfolded form will be stretched compared with that when folded. And the length measurement scale 4 also can be realized by painting different colors on different teeth ring...

Embodiment 3

[0037] Such as image 3 with 4 As shown, the present embodiment is substantially the same as the previous embodiment, except for the following differences:

[0038] The accordion-shaped folded tube wall 10 in the previous embodiment is replaced by a helically folded tube wall 11 in this embodiment. The helically folded tube wall 11 refers to the tooth-shaped folded structure of the tube wall, in which a single tooth no longer forms a closed loop like an organ, but forms a cylindrical helix, and the grooves between the teeth are formed by The organ-like disconnection becomes a connection from beginning to end. The nylon thread 8 of the present embodiment is wound along the groove formed by the aforementioned helically folded pipe wall 11, and the winding direction of the nylon thread 8 is from the tail end of the straight pipe section 3 to the head end of the straight pipe section 3, and is located in the groove. The inner nylon wire 8 is clamped by the adjacent pipe walls o...

Abstract

The invention provides a fallopian tube stent. The stent comprises an elastic hollow tube body, and the elastic hollow tube body comprises a straight tube section, a first curled section arranged at the head end of the straight tube section and a second curled section arranged at the tail end of the straight tube section. The stent can support and drain the fallopian tube, postoperative adhesion and obstruction are reduced, and the success rate of the operation is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a fallopian tube stent. Background technique [0002] The fallopian tube is divided into 4 parts from inside to outside according to the shape: interstitium, isthmus, ampulla, and umbrella. Clinically, 80% of infertility patients are caused by fallopian tube factors. Fallopian tube obstruction is often blocked by adhesion, congestion, and edema of the fallopian tube wall due to induced abortion, spontaneous abortion, drug abortion, induced labor, unclean sexual intercourse, and pelvic infection. Drug treatment of blocked fallopian tubes is generally ineffective, and surgery or IVF is required to solve fertility problems. The proportion of people who choose to do IVF due to infertility caused by blocked fallopian tubes accounts for about 60% of the total number of IVF babies. [0003] Due to the narrow lumen of the fallopian tube, the precision of the operation is very high. Lap...
