Three-dimensional developing coronary artery guide wire

Abstract

The invention provides a three-dimensional developing coronary artery guide wire which comprises a guide wire mandrel, wherein the guide wire mandrel comprises a torsion control section with an insulated periphery and a soft section fixedly connected to the front end of the torsion control section, the torsion control section is used for controlling operation of the guide wire, a first head end electrode is arranged at the head end of the soft section, and a second head end electrode is arranged at the tail end of the soft section, a second head end electrode is arranged at the position, located behind the first head end electrode, of the outer side wall of the soft section, a first tail end electrode is arranged at the tail end of the torsion control section, a second tail end electrode is arranged at the position, located in front of the first tail end electrode, of the outer side wall of the torsion control section, and the second head end electrode and the second tail end electrodeare exposed outside; the first head end electrode is electrically connected to the first tail end electrode, and the second head end electrode is electrically connected to the second tail end electrode. Through three-dimensional positioning and electrical characteristics, the use of X-rays can be greatly reduced finally, operation safety is improved, and radiation injury to patients and medical staffs is greatly reduced.

Description

technical field [0001] The invention relates to the field of surgical auxiliary instruments, in particular to a three-dimensional imaging coronary guidewire. Background technique [0002] Coronary artery disease is the most common cause of sudden death. One of the best treatments is interventional surgery. One of the most commonly used and most critical equipment is the coronary guide wire, which is used to guide the materials that need to be placed in the blood vessel during the intervention. Such as catheters, stents, balloons, etc. [0003] The traditional technology of guide wire operation is performed under X-ray irradiation. Due to the limited definition of X-rays on viscera and blood vessels and the inherent deception of the two-dimensional view, the failure rate and risk of the operation remain high, and the treatment of complex lesions The time and dose of X-ray irradiation are also very alarming. Since the 21st century, the three-dimensionalization of interventio...
