Fallopian tube recanalization assembly

Abstract

The invention relates to instruments and apparatuses for the gynaecology and obstetrics department, in particular to a fallopian tube recanalization assembly. The fallopian tube recanalization assembly comprises a dual-cavity sacculus catheter and a guide wire, wherein the dual-cavity sacculus catheter is provided with a sacculus cavity and a guide wire cavity. A deflection sacculus is arranged at the front portion of the dual-cavity sacculus catheter. The top end of the dual-cavity sacculus catheter is in a smooth arc shape. Three holes are formed in the front end of the dual-cavity sacculus catheter, and the three holes include a guide wire through hole in the top end, and a first liquid outlet and a second liquid outlet which are symmetrically distributed in the two sides. The tail end of the dual-cavity sacculus catheter is forked into a sacculus cavity tail section and a guide wire cavity tail section. A check valve is fixedly connected with the tail end of the sacculus cavity tail section, and a guide wire is a straight-head guide wire. According to the fallopian tube recanalization assembly, the liquid outlets are formed in the two sides, and therefore positioning is accurate during operations; the straight-head guide wire can smoothly enter the fallopian tube during operations, and therefore the pain degree of a patient and damage to the uterine cavity are reduced; an eccentric air bag is used in cooperation with the liquid outlets in the two sides, the length of the guide wire is accurately controlled, and therefore operability can be better achieved during operations, operation time is shortened to 0.3 hour to 0.5 hour compared with traditional operation time of 1 hour to 1.5 hours, and the operation success rate is greatly increased to 85%.

Description

technical field [0001] The invention relates to an obstetrics and gynecology instrument, in particular to a fallopian tube recanalization component. Background technique [0002] With the development of society, the incidence of female infertility is increasing year by year, and tubal factors account for the highest proportion of female infertility, accounting for 35%. Miscarriage, uterine and pelvic inflammation often lead to blocked fallopian tubes. Therefore, interventional recanalization of fallopian tubes has become an important method for its treatment. Currently on the market there are mainly the fallopian tube dredging suit provided by COOK Company of the United States and the goose-head integrated fallopian tube recanalizer of the domestic Nanjing Minimally Invasive Company. The recanalization tube of the former is composed of a tapered catheter head and a cervical suction cup. After the guide wire enters the uterine cavity, it is difficult to find the opening of ...

Problems solved by technology

But the guide wire of this patent is barb shape, and the guide wire of barb shape is better because can prevent blood vessel from being punctured when entering human body blood vessel, but when entering fallopian tube, when entering from uterine cavity phase fallopian tube isthmus , due to the barb shape, it is easy to form an arc, and it is difficult to probe the entrance of the isthmus of the fallopian tube

At the same time, the material of the entire recanalizer is hard plastic, and there is a part of soft material in the front part. Since the uterus of most women has a certain curvature during the operation, the hard and vertical recanalizer will It increases the difficulty of the operation and causes more pain for the patient; in addition, the patented recanalizer is designed with a single hole. When it is inserted into the isthmus of the fallopian tube, it is difficult for the contrast agent to enter the uterine cavity to display the cornu of the uterus due to the single hole. , so it is not conducive to accurate positioning in surgery
