Embodiment Construction
[0011] Below in conjunction with accompanying drawing, specific embodiment of the present invention is elaborated:
[0012] Such as figure 1 The shown interventional catheter with a tip and a hard tip includes a main catheter 1 and a sharp tip 2 that is shorter than the main catheter 1 and harder than the main catheter 1, and the tip hard tip 2 is tightly sleeved on the main catheter 1 At one end of the inner cavity 3, the main conduit 1 and the tip hard head 2 are welded together by high frequency through the tip mold, and the main conduit 1 is a single-lumen or multi-lumen tube.
[0013] A method for manufacturing an interventional medical catheter with a hard tip at the tip of the head, comprising: a single-lumen or multi-lumen main catheter 1 made of a composite polymer material through precision extrusion, and a composite polymer material slightly harder than the main tube through precision extrusion Precisely match the tip hard tip 2 of the inner cavity, place the tip h...
