Problems solved by technology

[0003] In the existing design and manufacture of catheters, most of them shape the distal end of the catheter into different curved shapes to meet different anatomical structures of blood vessels, so that the catheter can pass through and reach the lesion, but this pre-shaped curved shape After entering the blood vessel, it is deformed and is no longer the shape that the surgeon wants, so it cannot reach the target position accurately, thus failing to meet the clinical needs

Abstract

The present invention discloses an adjustable bent sheathing canal. The adjustable bent sheathing canal comprises a shell body, a canal body, traction wires and a bending adjusting device; the shell body is provided with an inner cavity; the canal body is provided with a near end and a far end, the near end of the canal body is arranged in the inner cavity in a penetrating mode, the far end of thecanal body extends out of the inner cavity, and a canal wall of the canal body is provided with at least one guide wire cavity; the traction wires are movably arranged in the wire guide cavities, oneends of the traction wires are connected with the far end of the canal body, and the other ends of the traction wires are connected with an inner wall of the shell body; and the bending adjusting device is arranged in the inner cavity and can pull the traction wires to bend the far end of the canal body. By means of the arrangement, the traction wires are pulled through the bending adjusting device, the far end of the canal body is bent under a pulling force of the traction wires, and thus the far end of the canal body can reach a needed position.

Description

technical field [0001] The invention relates to the technical field of vascular intervention catheters, in particular to an adjustable curved sheath. Background technique [0002] Vascular interventional catheters are used in minimally invasive surgery to establish access, deliver instruments or drugs, etc. [0003] In the existing design and manufacture of catheters, most of the distal ends of the catheters are shaped into different curved shapes to meet different anatomical structures of blood vessels, so that the catheter can pass through and reach the lesion, but this pre-shaped curved shape After entering the blood vessel, it is deformed and is no longer the shape that the surgeon wants, so it cannot reach the target position accurately, so it cannot meet the clinical needs. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes an adjustable c...
