Embodiment

[0129] Such as Figure 1-9b As shown, the sinus balloon catheter system of this embodiment includes a sinus guide catheter assembly, a sinus balloon catheter body 3 and a sinus guide wire 6 . Wherein, the sinus guiding catheter assembly includes a sinus guiding catheter 1, a sinus control handle 2 and a control structure. The front end of the sinus guiding catheter 1 can be bent by an angle α through the control structure to form a bending area, wherein 0°≤α<180°, which can meet the needs of complex sinus cavities during use. The curved area at the front end of the sinus guiding catheter 1 is made of soft bendable metal tube, and the rear end is made of hard, inflexible material. On the upper surface 21 and the lower surface 22 of the front end metal tube 20, respectively set up a slot 23, the depth of the slot 23 is 0.4 of the diameter of the metal tube 20, the slot 23 area of ​​the upper surface 21 and the slot 23 of the lower surface 22 The area is symmetrical with respec...

Abstract

The invention discloses a paranasal balloon catheter system. In particular, the system comprises a paranasal guiding catheter assembly which comprises a paranasal guiding catheter, a paranasal control handle and a control structure. The paranasal guiding catheter and the paranasal control handle are integrated or are integrally formed; the control structure is used for controlling the bending angle of the front end of the paranasal guiding catheter; the front end of the paranasal guiding catheter can bent at an angle of alpha to form a bent region, wherein alpha is greater than or equal to 0 degree but smaller than 180 degrees; a side slot is formed in the paranasal control handle; a balloon is arranged on the paranasal balloon catheter body, a flushing hole is formed in the tip of the balloon, and a thread-guiding channel is formed in the center of the paranasal balloon catheter body; and a thread-guiding label tape is arranged on the outer surface of the paranasal guided thread, and the paranasal guided thread located in the side slot and the thread-guiding channel can move back and forth. The paranasal balloon catheter system disclosed by the invention is simple in structure, convenient to operate, suitable for the structure of the paranasal cavity and convenient for quickly and efficiently implementing a nasal endoscope minimally invasive surgery.

Description

technical field [0001] The invention relates to the field of medical devices, and more particularly relates to a sinus balloon catheter system. Background technique [0002] The nasal cavity and sinuses are located below the skull, above the throat and mouth, and between the eye sockets. Nasal cavity and sinus lesions often spread to nearby tissues, which can cause various complications. Sinusitis is usually found in the nasal cavity examination, there is purulent secretion in the nasal passage or olfactory cleft, and the middle turbinate and middle nasal passage mucosa are thickened or polypoid. For multiple sinusitis, it can be used as negative pressure replacement therapy, and for suppurative upper collar sinusitis, it can be used for upper collar sinus puncture. People with mechanical obstruction factors such as nasal polyps, hypertrophy of the middle turbinate, curved nasal septum, and hypertrophy of the adenoids may hinder the ventilation and drainage of the sinuses ...
