The invention discloses a
guide catheter. The
guide catheter comprises an inner tube, an outer tube and a drive device, wherein one end of the inner tube can be bent and is used for conveying instruments, the inner tube is sleeved with the outer tube, one end of the outer tube can be bent, the bendable end of the outer tube and the bendable end of the inner tube are fixedly connected, and the drive device is connected with the other end of the inner tube and the other end of the outer tube, the drive device axially pulls the inner tube in the direction far away from the bendable end of the outer tube relative to the outer tube. When the
guide catheter is used, the drive device is started, pulling force is exerted on the inner tube, one end of the outer tube and one end of the inner tube are both bendable, the outer tube is tensioned under the action of the pulling force, so that the inner tube is driven to be bent at the same time, and the angle of the guide
catheter can be adjusted by adjusting the pulling force of the drive device. The problem that during
surgery, the guide
catheter is replaced repeatedly is solved, the
surgery time is shortened, and efficiency is improved. Due to the fact that the angle of the guide
catheter can be changed, it can be guaranteed that the guide catheter meets different angle requirements, and the success rate of
surgery is increased. In addition, the bendable end of the guide catheter is rotatable.
