Description

Technical Field

[0001] The invention belongs to the technical field of heat treatment of coronary stents, and in particular relates to a heat treatment device for a metal degradable heart coronary stent. Background Art

[0002] Coronary stents are determined based on the severity of vascular lesions. Coronary stent implantation is also called percutaneous coronary stenting. Implantation only requires local anesthesia, not general anesthesia. The stent is delivered to the severely narrowed coronary artery through a catheter through percutaneous puncture, and the lesion can be completely occluded by releasing it. The operation takes longer and local anesthesia is required during the operation.

[0003] Coronary artery stent refers to selecting an artery from the patient's hand or leg, making a small incision, and then slowly inserting a catheter along the guide wire to the bottom of the coronary sinus. Then, selective angiography is performed on the left and right coronary arteries. After confirming that the patient's coronary artery is stenotic, a balloon is inserted to partially expand the stenotic blood vessel. After expansion, the balloon is removed and the stent is selected. The stent reaches the stenotic site and an external pressure pump is used to release the pressure. In this case, the blood vessel can be expanded and opened.

[0004] At present, in the processing of coronary stents, the unformed stent material - nickel-titanium alloy memory wire needs to be heat treated. Among the heat treatment methods currently used, the most commonly used is the trolley-type heat treatment furnace. There is a difference between manual and automatic use of this heat treatment furnace. In manual use, there is efficient automation for feeding and unloading of workpieces, but the cost of use is high, the purchase cost is large, and the subsequent maintenance is cumbersome, which is not suitable for use in small workshops; while in manual operation, there will be fatigue and low operating efficiency.
