Cardiovascular interventional therapy device

Abstract

The invention relates to the cardiovascular technical field, and in particular relates to a cardiovascular interventional therapy device. The cardiovascular interventional therapy device comprises anouter needle cylinder, an inner needle cylinder and a needle head installed at the end of the outer needle cylinder; the needle head is communicated with the interior of the inner needle cylinder andused for allowing a guide wire to penetrate through; the end of the inner needle cylinder can move in an inner cavity of the inner needle cylinder through a piston; the cardiovascular interventional therapy device further comprises a base; the base is used for fixing the moving distances of the outer needle cylinder and the inner needle cylinder in an inner cavity of the outer needle cylinder; a through hole is formed in the inner needle cylinder; and an electromagnetic elastic piece is arranged at the position, corresponding to the through hole, of the inner wall of the outer needle cylinder.The cardiovascular interventional therapy device disclosed by the invention has the characteristics of being convenient to operate and accurate in positioning.

Description

technical field [0001] The invention relates to the field of cardiovascular technology, in particular to a cardiovascular interventional treatment device. Background technique [0002] Cardiovascular disease, also known as circulatory system disease, is a series of diseases involving the circulatory system. The circulatory system refers to the organs and tissues that transport blood in the human body, mainly including the heart, blood vessels (arteries, veins, capillaries), and can be subdivided into acute and chronic, are generally related to arteriosclerosis, in cardiovascular interventional treatment, the puncture needle is first inserted into the patient's blood vessel, and then the guide wire is sent into the blood vessel through the puncture needle, usually through the ordinary injection device through the puncture needle into the blood vessel , it is inconvenient for people to control the penetration depth; when the puncture needle is inserted into the patient's blood...
