Abstract

The invention provides a balloon catheter retractor, which comprises a balloon catheter and a balloon fixed to the balloon catheter; when fluid is filled into the balloon, the balloon is bent, and the balloon catheter is pulled to bend correspondingly; The balloon catheter retractor is characterized in that a radial limit is applied to the balloon, so that the balloon does not expand in the diameter direction when expanding to a certain diameter. According to the invention, the bending capability can be enhanced, and the characteristic of keeping the bending performance can be enhanced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a balloon catheter retractor. Background technique [0002] There are the following two solutions for the use of balloons to retract the esophagus retractor: [0003] A non-compliant material is used to create a C-profile balloon. Before use, the residual air in the balloon is evacuated by suction, and a rigid straight guide wire is passed through the balloon axis to adjust the C-shaped collapsed balloon into a straight line. . When in use, the balloon is sent into the esophageal lumen, the rigid straight guide wire is drawn out, and the liquid is injected and maintained at a certain liquid pressure (greater than 4 atmospheres), the balloon will return to the prefabricated C-shaped structure and provide support. So as to achieve the purpose of pulling. However, in this way, due to the use of a non-compliant balloon, the initial diameter of the balloon is relatively thick, usuall...
