The invention provides a Tip head section tear-resistant catheter which comprises a main body section and a Tip head section, the catheter comprises an outer layer and an inner layer, the outer layer and the inner layer are arranged from outside to inside in the radial direction of the catheter, and the Tip head section is provided with a reinforcing structure to prevent the Tip head section from being torn. Through the reinforcing structure of the catheter Tip head section, the rigidity and the strength of the catheter Tip head section are enhanced, the radial supporting force resistance of the catheter Tip head section is improved, and the risk that the catheter Tip head section is expanded to form a horn mouth and then is torn is reduced. 本发明提供了一种Tip头段抗撕裂导管，包括：主体段和Tip头段，所述导管包括外层和内层，所述外层和所述内层沿所述导管的径向自外向内设置，所述Tip头段具有加强结构，以防止所述Tip头段撕裂。通过上述导管Tip头段的加强结构，增强了导管Tip头段的刚度和强度，提升了导管Tip头段的抗径向支撑力，降低导管Tip头段被撑大成喇叭口进而导致撕裂的风险。
