Visual three-level paranasal sinus balloon dilatation flushing catheter system

Abstract

The invention discloses a visual three-level paranasal sinus balloon dilatation irrigation catheter system. The visual three-level paranasal sinus balloon dilatation irrigation catheter system comprises a catheter assembly, a guide assembly, a visual shooting assembly and a handle assembly, wherein the first end of the catheter assembly penetrates through the handle assembly and is embedded in theguide assembly, and the second end of the catheter assembly is exposed out of the handle assembly; the catheter assembly comprises a connecting pipe and a three-level balloon arranged on the connecting pipe; the first end of the guide assembly is detachably connected with the handle assembly, and the second end of the guide assembly is exposed out of the handle assembly; the visual shooting assembly is detachably connected to the catheter assembly; and the guide assembly comprises a guide catheter, and a bent part is further arranged at the end of the guide catheter and made of a flexible material. According to the visual three-level paranasal sinus balloon dilatation irrigation catheter system, the visualization function, the guiding function, the balloon dilatation flushing function andthe imaging function can be integrated into a whole, balloons of three different diameters can be integrated, the visual three-level paranasal sinus balloon dilatation irrigation catheter system is simple, convenient to use and effective, and the operation time is shortened.

Description

technical field [0001] The application belongs to the technical field of medical devices, and in particular relates to a visualized three-stage nasal sinus balloon dilatation irrigation catheter system. Background technique [0002] In the method of treating sinusitis dilatation in the existing catheter products on the market, a device for treating sinusitis dilatation composed of relatively independent parts with balloon expansion function, guiding function, lighting function and flushing function is often used. Doctors are required to assemble each product separately. Due to the possibility of damage to the parts during the scattered assembly of functional parts, there are risks in the use process. Moreover, the product is inconvenient to assemble and operate with individual parts, and the steps are cumbersome, so the operation time is longer. . Contents of the invention [0003] In view of the shortcomings or deficiencies of the above-mentioned prior art, the technical...
