Easy-to-control angiographic catheter

Abstract

The invention discloses an easy-to-control angiographic catheter. The easy-to-control angiographic catheter comprises a catheter, a steering mechanism and an operating mechanism, wherein the catheteris provided with an inner cavity through which a contrast agent passes, the catheter is further provided with an accommodating cavity extending along the axial direction of the catheter, and an operating channel communicating with the accommodating cavity, the steering mechanism is arranged in the accommodating cavity, the steering mechanism comprises a top block, a bottom block and a curved elastic part, two ends of the elastic part are connected with the top block and the bottom block respectively, the operating mechanism comprises an operating rod and an operating handle, the operating rodcan penetrate into the operating channel, the operating rod can penetrate through the bottom block, and is connected with the top block in a clamping manner, the rigidity of the operating rod is greater than the rigidity of the elastic part to make the operating rod support the elastic part, and the operating handle is connected with the operating rod. When the catheter needs to be inserted into atarget blood vessel, the operating rod is controlled by the operating handle, so that the operating rod is separated from the top block, and the elastic part is bent and reset, so that the catheter is driven to be actively bent and inserted into the target blood vessel, the operation difficulty and time are reduced, and carrying-out of an operation cannot be affected.

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...
