The minimally invasive interventional medical engineering or minimally invasive medical technology is a brand new technology which is rapidly developed in recent years and discloses a new chapter of medical science and technology. Minimally invasive interventional medical engineering is a diagnostic and therapeutic procedure performed by using a series of interventional instruments and materials (or called minimally invasive instruments and materials) and modern digital medical devices. Compared with the traditional surgical operation, the interventional therapy is carried out without operation, and the device has the advantages of less bleeding, small wound, less complication, safety, reliability, and recovery from a Shaan operation, greatly relieves the pain born by a patient, reduces the operation difficulty of an operator, obviously shortens the hospitalization time caused by the operation time, and obviously reduces the cost.
The medical catheter is an important instrument for minimally invasive interventional therapy, the materials used by the medical catheter are various, the medical catheter mainly comprises biomedical materials, medical catheter plastics and the like, and the medical catheter can be used on medical catheters with different purposes by different performances, such as: interventional cardiac catheters, peripheral catheters, cranial nerve catheters, and the like.
In the process of making the microcatheter, due to the fact that the tubes made of different materials or different outer diameters need to be spliced or combined, the heat shrink tubes are nested on the outer surfaces of the tubes, the tubes are subjected to hot melting, after the combination is completed, the heat shrink tubes need to be removed from the tubes to be stripped, and then stripping jigs need to be used.
The traditional pipe stripping mode is that workers hold a cutter, so that the working efficiency is low; meanwhile, the longer pipe body is cut into the heat shrinkable pipe, so that the fatigue of personnel is easily caused, and the outer layer of the micro-catheter is damaged due to uneven force; from the operation aspect, manual operation requires that operators have higher proficiency; the skill level of the personnel requires companies to expend significant resources for training; from the material layer, can adopt tearing type pyrocondensation pipe, realize peeling off, but because the higher reason of price, thus lead to the cost increase.
