Problems solved by technology

[0003] In the related art, during percutaneous coronary intervention, instruments such as guide wires and microcatheters are pushed from the extended guiding catheter to desired positions in the coronary artery. However, due to the diameter of the pushing part of the extended guiding catheter in the related art The size of the direction is too large, which is not conducive to the delivery of guide wires, microcatheters and other instruments, thus increasing the difficulty of surgery

Abstract

The invention relates to an extended guiding catheter. The extended guiding catheter comprises an operation interface, a pushing part and a catheter which are sequentially connected from the near end to the far end, wherein the catheter is provided with a channel which is through in an axial direction and used for conveying instruments, a balloon is arranged on the periphery of the catheter in a surrounding mode and is in fluid communication with the operation interface, the pushing part is provided with a connecting component used for connecting the operation interface with the catheter and a flow channel used for communicating the operation interface with the balloon in a fluid mode, and at least part of the connecting component is embedded in the flow channel. According to the scheme, the maximum radial size of the pushing part is reduced, and conveying of instruments such as guide wires, micro-catheters and the like is better facilitated.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to extending guide catheters. Background technique [0002] Percutaneous coronary intervention (PCI) surgery refers to the treatment method of dredging the narrowed or even occluded coronary artery lumen through cardiac catheterization, thereby improving the blood perfusion of the myocardium. The operation has the advantages of short course of treatment, less trauma, and remarkable curative effect, and has developed rapidly in recent years. [0003] In the related art, during percutaneous coronary intervention, instruments such as guide wires and microcatheters are pushed from the extended guiding catheter to desired positions in the coronary artery. However, due to the diameter of the pushing part of the extended guiding catheter in the related art Excessive size is not conducive to the delivery of guide wires, microcatheters and other instruments, thus increasin...
