An Angiography Catheter that is Convenient to Manipulate

Abstract

The invention discloses an easy-to-manipulate angiography catheter, which comprises a catheter, a steering mechanism and an operating mechanism. The catheter is provided with an inner cavity through which the contrast medium passes, and the catheter is also provided with an accommodating cavity extending along its axial direction and an operation channel communicating with the accommodating cavity. The steering mechanism is arranged in the accommodating cavity, and the steering mechanism includes a top block, a bottom block and a curved elastic piece, and the two ends of the elastic piece are respectively connected to the top piece and the bottom piece. The operating mechanism includes an operating rod and an operating handle. The operating rod can penetrate into the operating channel, and the operating rod can pass through the bottom block and be detachably engaged with the top block. The rigidity of the operating rod is greater than that of the elastic member, so that the operating rod supports The elastic part is connected with the operating handle and the operating rod. When the catheter needs to be inserted into the target blood vessel, the operating handle is used to control the operating rod to separate the operating rod from the top block, and the elastic part is bent and reset, so that the catheter is actively bent and inserted into the target blood vessel, which reduces the difficulty and time of operation and will not affect the operation carried out.

Description

technical field [0001] The invention relates to the technical field of catheters, in particular to an angiography catheter that is easy to manipulate. Background technique [0002] Peripheral vascular disease refers to a narrowing or occlusion or tumor-like dilatation of the aorta and its branches other than the coronary arteries. It is mainly based on atherosclerosis, including carotid arteriosclerosis, renal arteriosclerosis and lower extremity arteriosclerosis, which is called peripheral vascular disease. It is more common in the elderly, especially hypertension, diabetes, obesity, blood lipid disorders and People who smoke. After the blood pressure rises, affected by the blood flow, the pressure on the arteries and branches will damage the vascular endothelium, thereby causing atherosclerosis. [0003] At present, the professional technology for the treatment of peripheral vascular diseases in our country is developing vigorously, the traditional surgical techniques ar...
