Method of marking medical interventional equipment

Abstract

The invention discloses a method of marking medical interventional equipment, and belongs to the technical field of the medical device manufacturing method. According to the medical interventional equipment labeling method, wire markers are used at the location of the interventional equipment in need of marking to closely intertwine in a same rotational direction to reach the marked length, liquid polyurethane is coated in the marked location, a first time curing is conducted, the two ends of the wire markers are cut and pressed along the curing edge, liquid polyurethane is again coated at the marked location, and a second time curing is conducted. The method of marking medical interventional equipment has the advantages that compared with the traditional laser marking and developing ring press grip, the interventional equipment does not produce any damages, the flexibility and fracture force of the original material are retained, the inner diameter of the equipment does not have any caused extrusions, the conveying of the inner diameter of the equipment is ensured to achieve the maximum size, the used materials are good in security, damages on human blood vessels and the non-vascular channels are reduced, and precision conveying of the marking of the equipment is achieved.

Description

technical field [0001] The invention relates to a marking method for medical interventional equipment, and belongs to the technical field of medical equipment production and processing methods. Background technique [0002] Percutaneous coronary intervention (PCI) technology is developing rapidly. Due to the advantages of good patient compliance, less bleeding complications, and less trauma, the radial artery has become the first choice for PCI surgery in many hospitals at home and abroad. However, transradial PCI also has certain limitations. When dealing with complex coronary lesions such as severe calcification, proximal distortion, or chronic occlusion, the interventional equipment is not flexible enough to successfully reach the target lesion area. [0003] In the existing interventional equipment products, all the metal developing rings are crimped or laser marking is used as the delivery size mark.

Problems solved by technology

However, transradial artery PCI also has certain limitations. When dealing with complex coronary lesions such as severe calcification, proximal distortion, or chronic occlusion, the interventional equipment is not flexible enough to successfully reach the target lesion area.

[0003] In the existing interventional equipment products, all the metal developing rings are crimped or laser marking is used as the delivery size mark. Although these two methods can guarantee the outer diameter size, they both require special customized equipment, and the cost is also high. In addition, the crimping metal The developing ring will lose the flexibility of the original product, and the inner diameter of the mandrel placement equipment needs to be reduced by a certain percentage. Laser marking will produce a strong smell and have high requirements for the clean room. Both methods will reduce the breaking force of the pipe. pose a security risk
