Abstract

The invention discloses a double-balloon catheter for blocking arteria iliaca communis blood. The double-balloon catheter comprises a catheter body, a far end balloon, a near end balloon, a developing ring, a catheter reinforcer and a catheter seat. The catheter body is composed of a tip end, an inner tube and an outer tube, the tip end is connected with the far end of the inner tube, the inner tube is located in the outer tube, and a guide wire channel is formed in the inner tube. A liquid injection channel is formed in the area between the inner tube and the outer tube, the far end of the liquid injection channel is communicated with the far end balloon, and the liquid injection channel is communicated with the near end balloon through a liquid injection hole. The far end balloon and the near end balloon are arranged in a spaced mode in the length direction of the catheter body, and the catheter body penetrates through the far end balloon and the near end balloon. The near end of the inner tube and the near end of the outer tube penetrate through the middle of the catheter reinforcer and are connected with the catheter seat. A main connector at the end of the catheter seat is communicated with the guide wire channel, and an auxiliary connector at the end of the catheter seat is communicated with the liquid injection channel. It is not needed to guide a guide wire into the human body arteria iliaca communis, the process of an arteria iliaca communis blocking operation is simplified, and operational difficulty is reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular, the invention relates to a double-balloon catheter for blocking the blood flow of the common iliac artery. Background technique [0002] Occlusion of the common iliac artery is often required during surgery for sacrococcygeal malignancy or placenta previa. At present, the commonly used clinical practice is to deliver a balloon catheter to the abdominal aorta and expand it through interventional surgery, so as to block the blood flow of the abdominal aorta and common iliac artery. However, the diameter of the balloon used in this method is large, and a sheath tube with a large outer diameter must be used, so the damage to the human body is also large. In addition, since the abdominal aorta is connected to the renal artery, when using a balloon catheter to block the blood flow of the abdominal aorta, it is necessary to always pay attention to avoid affecting the renal artery, which vi...
