AI Technical Summary

Technical Problem

During interventional treatment, the delivery sheath is easily offset or deformed when the inner catheter is twisted, making it difficult to accurately locate the implanted device, increasing the difficulty and duration of the operation.

Method used

Design a type of sheath tube. The tube contains the main segment and the bending section, and at least one enhanced tendon is arranged upwards to enhance its resistance to reversing and anti -migraine.

Benefits of technology

By strengthening the existence of gluten, the conveyor sheath is not easy to offset or deforms when the inner tube is reversed. It can stabilize the original direction, reduce compensation regulation, and improve the adjustment efficiency and accuracy of the conveying system.

Abstract

The invention provides a conveying sheath tube and a conveying system. The conveying sheath tube comprises a tube body and at least one reinforcing rib. The pipe body comprises a main body section and a bendable section in the axial direction. The pipe body comprises a lining, a reinforcing layer and an outer layer which are arranged from inside to outside in the radial direction, and the reinforcing layer is one or a combination of more of a spring coil, a metal woven mesh or a cutting hypotube. The at least one reinforcing rib is arranged in the pipe body in the axial direction of the pipe body, and the at least one reinforcing rib is arranged on the bent outer side of at least part of the bendable section or is arranged to be symmetrically distributed with the axial section of at least part of the pipe body as the symmetry plane and relatively close to the bent outer side. By improving the structure of the conveying sheathing canal, the supporting performance and the torsion and deflection resisting performance of the conveying sheathing canal are improved, and therefore conveying can be better carried out.
