Fallopian tube jam diagnosis and treatment device

Abstract

The invention belongs to the technical field of medical appliances, and particularly discloses a fallopian tube jam diagnosis and treatment device. The fallopian tube jam diagnosis and treatment device comprises a connector and a sleeve body, wherein the sleeve body comprises a guide wire, a microcatheter, a cornua uteri catheter, an external catheter and a ball bag which are connected in a sleeving manner from inside to outside; a hydrophilic coating coats the guide wire; a net-shaped film coats the outer wall of the microcatheter; a far end of the cornua uteri catheter is a conical elbow; the connector is connected with a microcatheter connecting tube, a catheter connecting tube and a ball bag three-way connecting tube in a penetrating manner; the ball bag three-way connecting tube is provided with a pressure gauge; one-way valves are separately arranged at the near end of the microcatheter connecting tube, the near end of the catheter connecting tube and the ball bag three-way connecting tube; and a net-shaped film wraps the outer wall of the microcatheter. By arrangement of the pressure gauge, pressure change in the ball bag can be judged accurately, over-filling or insufficient filling caused by inaccurate pressure judgment in the ball bag is prevented, and by the conical elbow, trauma to endometrium and fallopian tubes is avoided effectively.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for diagnosing and treating blockage of fallopian tubes. Background technique [0002] Tubal dredging is the treatment of female infertility caused by tubal stenosis or blockage caused by fallopian tube or pelvic peritonitis. The commonly used tubal dredging in clinical practice includes transcervical tubal dredging and laparoscopy combined with tubal dredging. [0003] At present, the structures of the devices used to dredge the fallopian tubes are varied clinically, and the product standards adopted are also different. The most commonly used device for dredging the fallopian tubes is a single catheter, through which the liquid is injected into the fallopian tubes and the uterine cavity. The internal expansion pressure is limited, resulting in mediocre dredging effect. [0004] American cook company fallopian tube dredging kit DBH-100 double balloon...

AI Technical Summary

Problems solved by technology

Both the distal end and the proximal end of the DBH-100 double-balloon catheter are equipped with silicone balloons, which can stabilize the fabrication and prevent the contrast agent from spilling out. However, the problem with the DBH-100 double-balloon catheter is that The amount of water injection required for each ghosting silicone balloon is determined by the experience of medical staff, and it is difficult to accurately judge the pressure change after the balloon is inflated in the body

FTC-550-NT includes elbow catheter, micro catheter, micro guide wire, double balloon catheter, etc. The head end of the elbow catheter has a braided mesh to enhance torque control. The micro catheter is made of nylon material. Radiopaque markers, the micro-guide wire is made of nickel-titanium material, and the head end is made of platinum material; however, the existing problem is that the head end of the elbow catheter is flat and the hardness is too high.
