Hysterosalpingography tube

Abstract

The invention provides a hysterosalpingography tube, which comprises an angiography tube, an inner support tube, an intervention guide wire and a corresponding catheter, wherein the head end part of the angiography tube is provided with an angiography tube end hole, an angiography tube side hole and a sacculus are arranged at the near head end part of the angiography tube, the tail part of the angiography tube is provided with an angiography tube tail end and a sacculus tube tail end, the sacculus is a symmetrical sacculus, the angiography tube tail end is matched with an injector, the outer diameter of the inner support tube can allow the inner support tube to be inserted into the angiography tube, an inner cavity of the inner support tube can allow the intervention guide wire to pass through, after being inserted into the angiography tube, the inner support tube and the intervention guide wire can simultaneously twist, the tail part of the inner support tube is provided with a first scale and a second scale, the tail end of the inner support tube is also matched with the injector. The hysterosalpingography tube has the advantages that the hysterosalpingography tube can be used for the hysterosalpingography, the problem of false positive in hysterosalpingography is avoided, the interventional recanalization operation of the obstructive oviduct can be completed under the condition without replacing other appliances, the injury to patients is reduced to the maximum degree, and good clinic application values are realized.

Description

technical field [0001] The invention relates to a hysterosalpingography tube, which belongs to the technical field of medical instruments. Background technique [0002] Among the factors of female infertility, tubal obstruction accounts for a large proportion, 30% to 50% according to statistics. The simplest and most effective way to diagnose tubal obstruction is hysterosalpingography, and the method of treating tubal obstruction is except In addition to traditional gynecological surgery, interventional recanalization is currently carried out in hospitals at all levels because of its simple operation, convenience and effectiveness, and low technical requirements. The catheters used for salpingography are basically commercially available disposable sterile hysterosalpingography catheters; and the devices used for tubal recanalization according to the various materials we have consulted show that most of them are made by the COOK company in the United States. The COOK-DHB100 ...
