More Information
Summary:The utility model discloses a laser ablation balloon catheter which comprises an inner catheter, an outer catheter, a balloon and a connector. A balloon is arranged on the outer catheter; the inner conduit is arranged in the outer conduit; an optical fiber bundle cavity is arranged between the outer catheter and the inner catheter, an optical fiber bundle is arranged in the optical fiber bundle cavity, and the connector is provided with an optical fiber interface; compared with radiofrequency ablation and cryoablation modes in the prior art, the laser ablation mode is adopted, higher precision and predictable ablation amount are achieved, accurate and continuous energy conveying can be achieved, and therefore oedema caused by an operation is reduced, and normal human tissue cannot be damaged; the endoscope cavity is further arranged, so that the visualization degree of the instrument in the operation process can be increased by using an endoscope, and the instrument can reach the focus position more accuratel
