Abstract

The invention belongs to the technical field of medical auxiliary equipment, and provides a guide catheter which comprises a main body tube, a guide tube, a guide tube and a guide tube. The bag body assembly is arranged in the cavity, the bag body assembly comprises an expandable bag body and an inner tube, one end of the inner tube is communicated with an external fluid source, the other end of the inner tube is communicated with the expandable bag body, the inner tube is used for injecting fluid into the expandable bag body or guiding the fluid out of the expandable bag body, and the expandable bag body is communicated with the inner tube. And the expandable bag body is switched between an expansion state and a contraction state. The inflatable bag body is arranged in the guide catheter, in the inflation state, the inflatable bag body can clamp instruments such as a guide wire or a micro catheter, and the difficulty of surgical operation is reduced.

Description

technical field [0001] The present application relates to the technical field of medical auxiliary equipment, and in particular provides a guiding catheter. Background technique [0002] Coronary artery chronic total occlusion (CTO) interventional treatment is an interventional treatment method that uses a microcatheter to support the guide wire, so that the guide wire can open the lesion, and then use a balloon to dilate the blood vessel. During the operation, the following situations often occur: because a completely occluded lesion is usually very blocked, it is difficult for the guide wire to pierce the lesion. The back of the microcatheter makes the operation more difficult; in addition, after the guide wire is in place, the microcatheter needs to be withdrawn and the balloon catheter needs to be replaced. Open, this will bring a certain degree of difficulty to the doctor. Contents of the invention [0003] In view of this, the present application provides a guiding...
