Problems solved by technology

[0004] However, when the fascial dilator is used for predilation, that is, during the process of inserting the kidney along the guide wire and then pulling it out, the shearing action of the fascial dilator will increase the risk of damage to the subcutaneous muscle and renal parenchyma

Abstract

The invention provides a balloon dilation catheter component and relates to the technical field of medical instruments. A wire guide passage and a balloon inflation passage are arranged in a main guide tube of the balloon dilation catheter component; the wire guide passage runs through the main guide tube along the extension direction of the main guide tube; a support tube made of stainless steelis arranged in the wire guide passage. The support tube made of stainless steel allows the step to be omitted where a fascial dilator is used to carry out pre-dilating; the main guide tube with a guide sheath is inserted directly along a guide wire; the risk that shearing action of the fascial dilator for pre-dilating causes injury to subcutaneous muscles and renal parenchymal tissue is decreased.In addition, the support tube helps improve the rigidity of the component herein; a false passage is rarely formed during insertion; no bending occurs; inserting is easier. When the balloon is fullyinflated, the end, close to the head, of the main guide tube, of the balloon is 60-90 degrees angled to the axis of the main guide tube. The balloon dilation catheter component also comprises a dilating sheath that is tearable.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a balloon dilation catheter assembly. Background technique [0002] Balloon dilatation catheter is a kind of medical intervention equipment, wherein, percutaneous renal balloon dilation catheter is used for safe, effective and rapid establishment of skin-kidney channel. [0003] In the prior art, the percutaneous renal balloon dilatation catheter includes a main catheter and a balloon, the main catheter is a flexible tube, and the balloon ring is arranged on the outer wall of the main catheter. During use, the user first penetrates the cannulated puncture needle into the renal calyx or renal pelvis, pulls out the needle core, indwells the needle tube, inserts the guide wire into the kidney along the needle tube, pulls out the needle tube, and indwells the guide wire; Use a fascial dilator for pre-dilation, that is, insert the fascial dilator into the kidney along the...
