Problems solved by technology

And there is no protection for the hard head after glue bonding
During the surgical operation, it is easy to cause the tube body and the injection molded part (hard head) to fall off, and the hard head after falling off directly falls inside the human body. Although the general hard head has the effect of X-tube imaging, this is only for the convenience of finding The specific position after the head falls off cannot solve the fundamental problem
Still end up requiring unnecessary surgery to remove the hard head after shedding
Unnecessary suffering and medical risk to patients

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...

Abstract

The invention discloses a pointed-end hard-head intervention catheter, which comprises a main catheter and a pointed-end hard head with hardness being higher than the hardness of the main catheter. The pointed-end hard head is tightly sheathed at one end of the inner chamber of the main catheter. The main catheter and the pointed-end hard head are welded together at high frequency through a pointed-end mold. Compared with the prior art, the pointed-end hard-head intervention catheter has the advantages of high safety and reliability and simple production process. The production cost is greatly reduced, the medical risk is avoided and the pointed-end hard-head intervention catheter can be widely used in the industry.

Description

technical field [0001] The invention relates to an interventional catheter, in particular to an interventional catheter with a tip and a hard head. Background technique [0002] Interventional medicine is a new technology that has developed rapidly in recent years. As the people's requirements for living standards are getting higher and higher. Especially as a medical device to be involved in the human body, it is safe and reliable to use, and avoiding medical hidden dangers and medical accidents is a major problem that must be solved. In order to meet the clinical requirements, the current interventional catheter with a tip and a hard tip basically makes the main catheter first, then injects a hard tip, and then glues the main catheter with glue. This method seems simple, but in the production process, there must be an extruder to extrude the pipe, and an injection molding machine to inject the hard head. Two major machines and molds are involved. And there is no protec...
