Abstract

The invention discloses an adjustable bent sheath suction catheter which comprises but is not limited to an adjustable bent pipe section and a bending adjusting device, the adjustable bent pipe section comprises an elastic inner pipe body, the inner pipe body has at least one bending degree of freedom, a plurality of channels are formed in the pipe wall, and each channel is arranged in an inward concave mode in the radial direction; the bending adjusting device is used for providing bending deformation force for the inner pipe body. The invention provides a suction catheter with an adjustable bent sheath, which is used for improving the turning capacity of the catheter at a bent position of a blood vessel after the catheter is introduced into the blood vessel, and can adjust a smaller curvature radius on the premise of not influencing the suction force.

Description

technical field [0001] The invention relates to a medical device for interventional treatment, and in particular to an adjustable curved sheath suction catheter for taking out thrombus in a blood vessel. Background technique [0002] One of the ways to treat thrombus blocking intracranial blood vessels is to use a suction catheter to suck the thrombus away. However, the blood vessels will have bends, and the ability to bend is not very good; Shaping, forming different curved shapes to adapt to the bend of the blood vessel, which is conducive to the passage of the catheter and reaching the lesion site, but this pre-shaped curved tube segment may not be suitable for other bends or blood vessel segments after access , there are still situations that affect the use. [0003] In addition, those skilled in the art have also done some research and patent applications on adjustable medical catheters, such as: [0004] (1) CN202011190226.4 - an adjustable elbow, which discloses an ...
