Tubal interventional treatment apparatus

Abstract

The invention discloses a tubal interventional treatment apparatus, comprising an outer catheter (5), an inner catheter slidable in the outer catheter and a micro catheter (2) slidable in the inner catheter; the inner catheter is composed of an inner catheter front segment (3) and an inner catheter rear segment (6), an end of the inner catheter front segment is provided with a metal positioning head (13), one end of the micro catheter is extensible out of a metal positioning ring, the other end of the micro catheter is connected with a liquid delivery tube (11), the inner catheter is provided with a wire hole (16), a tractive wire fixedly connected at one end with the end of the inner catheter front segment and connected at the other end with a winder is arranged in the wire hole, and the end of the inner catheter front segment can be curved by rotating the winder. In use, the apparatus never injures the surface of the uterus cavity; since the end of the inner catheter front segment is bendable, it is convenient for accurately inserting the inner catheter into an opening of the fallopian tube, intervention takes a shorter time, radiation damage of X-ray to human bodies is reduced and pain of a patient is lessened.

Description

technical field [0001] The invention relates to a medical device, in particular to an interventional treatment device for fallopian tube recanalization, which includes the treatment of diseases in the fallopian tube such as selective radiography of the fallopian tube, dredging of the fallopian tube, double plug of the fallopian tube, and interventional treatment of ectopic pregnancy. Background technique [0002] Interventional tubal recanalization, that is, under the digital X-ray machine, the doctor uses a coaxial catheter system under the direct view of the TV screen to insert the tubal catheter through the vagina, cervix, uterus, and uterine horn, and performs selective salpingography and tubal opening. According to the specific conditions of the fallopian tube, the micro guide wire is inserted into the fallopian tube through the fallopian tube, and the micro guide wire is inserted into the fallopian tube opening first, and then the micro catheter is inserted into In the...

Problems solved by technology

Regardless of which of the above-mentioned surgical interventional treatments, the interventional treatment devices currently used include imported coaxial 3F microcatheters or 5F inner catheters and 0.018 microguide wires. This interventional treatment device has the following problems in the treatment process: First, the inner catheter As a whole, in order to make the front end of the inner catheter suitable for the curvature of the uterine wall, the inner catheter is made of plastic with a certain hardness. Since the extension arc of the uterine wall varies from person to person, the curvature of the front end of the inner catheter is fixed. , when operating the inner catheter, some endometrium that does not match the angle of the inner catheter at the front will cause damage and bring pain to the patient, especially for patients with long and narrow cervix, narrow adhesions, and partially deformed uterus when performing tubal interventional therapy , the front end of the internal catheter with a certain rigidity is not easy to enter the uterus or fallopian tubes. After entering, the operation of the microcatheter will cause damage to the endometrium, and may cause uterine perforation and bleeding in severe cases; It is a rubber metal positioning head, but under the DSA digital X-ray machine, the positioning time of the inner catheter is long, which increases the radiation damage of X-rays to the human body; moreover, the interventional treatment of the fallopian tube with this inner catheter can only be performed with expensive DSA digital X-ray machines can only be completed in hospitals, and it is not suitable for interventional treatment of fallopian tubes under B-ultrasound in grass-roots hospitals.
