Abstract
The utility model relates to a multifunctional angiography catheter which comprises a catheter head, a first bend, a second bend, a third bend and a catheter, wherein the front end of the catheter is provided with the catheter head; the catheter is provided with the first bend; a 360-degree angle is formed between the first bend and the opposite direction of the catheter; and the catheter is provided with the second bend and the third bend. The product is simple in structure and reasonable in design; the front end of the catheter is provided with the catheter head, and the 30-degree bend is formed at the catheter head along the direction opposite to that of the catheter, so that the probability of the misguided conus branch of the coronary artery angiography is greatly reduced; and meanwhile, the radiography success rate of right coronary artery with abnormal opening can be increased, the X-ray projection time is shortened, and the radiography cost of a patient is reduced.
Description
Technical field: this utility model relates to a kind of multi-functional blood vessel angiography catheter.
Background technology: at present, when Vasculocardiology Deparment carries out Transradial Approach right coronary artery radiography according to a conventional method, the distance of catheter tip to the first bending is slightly long, after rotating into RCS, its most advanced and sophisticated upper right side of easily pointing to, the position is slightly high, be easy to the super circular cone of selecting to enter the right coronary artery open proximal and prop up or artery of sinoatrial node, and above-mentioned blood vessel diameter is thinner, is easy to occur decline of pressure or incarceration, at this moment, such as the bolus administration of contrast agent of exerting oneself, ventricular fibrillation or coronary artery dissection very easily occur, and right coronary artery develops not good enough, this situation can only be used the JR conduit instead, but has increased x-ray projection time and radiography expense.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of multi-functional blood vessel angiography catheter is provided, it has mainly solved the angiocardiography conduit, the distance of catheter tip to the first bending is slightly long, after rotating into RCS, its most advanced and sophisticated upper right side of easily pointing to, the position is slightly high, be easy to the super circular cone of selecting to enter the right coronary artery open proximal and prop up or artery of sinoatrial node, the problems such as decline of pressure or incarceration occur.The purpose of this utility model is achieved in that a kind of multi-functional blood vessel angiography catheter is made of: conductor housing, the first bending, the second bending, the 3rd bending, conduit.Front end at conduit is provided with conductor housing, and the length of conductor housing is 4-6mm, and conduit is provided with the first bending, and the first bending is 30 degree angles in the other direction with conduit, and conduit is provided with the second crooked and the 3rd bending.This product structure is simple, reasonable in design, owing to being provided with conductor housing and conductor housing place conductive pipe is the curved of 30 degree angles in the other direction at the front end of conduit, making coronarography be strayed into the probability that circular cone props up reduces greatly, improved simultaneously the radiography success rate of the unusual right coronary artery of opening, reduce the x-ray projection time, reduced patient's radiography expense.
