Problems solved by technology

However, coronary artery calcified lesions often run through various complex lesions, which will affect the performance of balloon dilatation catheters. Protective measures are set outside the point, so that when encountering calcified lesions, it is easy to cause the distal end of the balloon to separate from the tube body, thereby causing leakage of the balloon and increasing the difficulty of coronary intervention

Embodiment Construction

[0024] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0025] This embodiment discloses an interventional medical catheter component welding method, such as figure 1 , the catheter part includes a tubular body 10 and a leading end 100 positioned at the distal end of the tubular body, and the welding method in this embodiment includes the following steps:

[0026] Provide at least two tip tubes that can be nested together;

[0027] First, if figure 1 , the first layer of tip tube 20 is sleeved on the leading end 100 of the tube body 10, and the first layer of tip tube 20 is fixed on the tube body 10 by welding;

[0028] Then, if figure 2 , the second layer of tip tube 21 is sleeved on the first layer of tip tube 20, and the second layer of tip tube 21 is welded on the first layer of tip tub...

Abstract

The invention discloses an intervention type medical catheter component welding method and a medical catheter, a catheter component comprises a catheter body and a guide end located at the far end of the catheter body, and the welding method comprises the following steps that at least two tip tubes which can be arranged together in a sleeved mode are provided; sleeving the guide end of the tube body with a first-layer tip tube, and fixing the first-layer tip tube on the tube body in a welding manner; sleeving the first-layer tip tube with a second-layer tip tube, and welding the second-layer tip tube on the first-layer tip tube; by parity of reasoning, a plurality of tip tubes are nested and welded on the tube body, so that a tip head is formed at the guide end of the tube body; by the adoption of the welding method, the guide end of the tube body can be firmer and more durable, serious calcification lesion can be more easily penetrated, and the success rate of an interventional operation is increased.

Description

technical field [0001] The invention relates to the technical field of medical catheters, in particular to an interventional medical catheter component welding method and a medical catheter. Background technique [0002] Percutaneous coronary intervention (PCI) can quickly open the infarcted coronary artery, improve myocardial blood supply, achieve ischemic myocardial reperfusion, and effectively treat angina pectoris, myocardial infarction, and acute coronary syndrome. As the most commonly used method of vascular reconstruction, PCI has the advantages of high opening rate and ideal effect. With the development of interventional therapy technology, the number of patients who choose PCI treatment is gradually increasing. However, coronary artery calcified lesions often run through various complex lesions, which will affect the performance of balloon dilatation catheters. Protective measures are set outside the point, so that when encountering calcified lesions, it is easy to...
