Fixing apparatus of hysterosalpingography catheter

Abstract

The invention relates to the technical field of medical equipment, and discloses fixing apparatus of a hysterosalpingography catheter. The fixing apparatus comprises a forceps and a fixer, wherein theforceps comprises two forceps arms, forceps heads of the two forceps arms are provided with inserting rods, an extension direction of the inserting rods is perpendicular to a rotation plane of the two forceps arms, the fixer comprises a fixing seat and a fixing pipe, an inner diameter of the fixing pipe is larger than a maximum outer diameter of a balloon of an angiography catheter before water injection and smaller than a maximum outer diameter of the balloon of the angiography catheter after water injection, and the fixing seat is provided with inserting holes. A size of the balloon of theangiography catheter after water injection is larger than an outer diameter of the fixing pipe to prevent the angiography catheter from falling off. A speculum is used to expose the cervix, the forceps is used to insert the fixer into the cervical canal, the uterine cavity operation is not needed, a catheterization time is greatly shortened, a catheterization success rate is improved, the stimulation to the cervix is reduced, and the cervical bleeding is avoided. After catheterization is completed, the inserting rods on the forceps can be removed from the inserting holes on the fixing seat toremove the forceps, and thereby an enough space is provided for the intracavitary ultrasound probe angiography operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a fixing device for a hysterosalpingography catheter. Background technique [0002] Blockage of fallopian tubes is one of the important factors causing female infertility, and its statistical proportion is 30%-50%. Therefore, diagnosing the patency of fallopian tubes is a must-do test item when determining the influencing factors of infertility. Diagnosis of fallopian tubes The simplest and most effective way to block is to use a salpingographic catheter to perform hysterosalpingography. [0003] Existing dual-lumen contrast catheters such as figure 1 As shown, it includes a tube body and a main cavity 101 and an auxiliary cavity 102 arranged in the tube body and isolated from each other. The main cavity 101 forms a channel for injecting a contrast agent, and the rear end of the tube body is provided with a contrast agent inlet 104 communicating with the main cavity ...
