Abstract
The utility model discloses an intervention catheter with a sharp-end hardening head, comprising a main catheter and the sharp-end hard head which is shorter than the main catheter and is larger than the main catheter in hardness; the sharp-end hard head is closely connected to one end of an inner cavity of the main catheter in a sheathed way; the main catheter and the sharp-end hard head are welded together in a high-frequency manner by a sharp-end mold. Compared with the prior art, the intervention catheter disclosed by the utility model has the advantages of safety, reliability and simple production process, also has the advantages that the production cost is greatly reduced and meanwhile the medical risk is also avoided, and is suitable for being widely used in the industry.
Description
Technical field
This utility model relates to a kind of interposing catheter, particularly relates to a kind of hardened sharp tip head interposing catheter.
Background technology
Interventional medicine is a brand-new technology that develops rapidly in recent years.Along with the people require more and more higher to living standard.Special medical apparatus and instruments as getting involved in human body, to safe and reliable, avoiding medical hidden danger and malpractice is to be faced with the significant problem that must solve.In order to satisfy clinical manipulation, present hardened sharp tip head interposing catheter is first to make main pipe substantially, then the injection moulding hardhead, then carries out main pipe bonding with glue.This method seems simply, but in manufacturing process, the extruder extruding pipe material must be arranged, injection machine injection moulding hardhead.Two large machine and moulds have been related to.And the hardhead after bonding with glue is without any protective measure.When carrying out operation technique, easily cause coming off of body and moulding (hardhead), the hardhead after coming off directly falls at inside of human body, although now general hardhead has the X-tube development effect, but this also just for the ease of seeking the particular location after head comes off, can't solve root problem.Finally still can cause unnecessary operation to take out the rear hardhead that comes off.Bring unnecessary misery and medical-risk to the patient.
The utility model content
The utility model purpose: this utility model has solved the deficiencies in the prior art, provides a kind of safe and reliable. the simple hardened sharp tip head of production technology interposing catheter.
Technical scheme: for achieving the above object, this utility model adopts following technical scheme:
A kind of hardened sharp tip head interposing catheter, comprise a main pipe and the most advanced and sophisticated hardhead shorter than main pipe and the hardness ratio main pipe is large, described most advanced and sophisticated hardhead closely is socketed in an end of main pipe inner chamber, and main pipe and most advanced and sophisticated hardhead are through most advanced and sophisticated mould high-frequency welding together.
As optimization, described main pipe is single chamber or multi-lumen tube.
a kind of conduit for interventional therapy hardened sharp tip head described in the utility model, by an available different hardness, the main pipe that unlike material is made, coordinate with main pipe by one more closely than slightly hard (hardness is adjustable) of main pipe through the conduit of special dies by high-frequency welding and molding, being applied to macromolecular material makes main pipe and through high-frequency welding, it is become again with the close-fitting hardhead pipe of main pipe inner chamber to be connected and to be communicated with at the band of one tip hardhead conduit by Precise Extrusion, main pipe's inner chamber head coordinates very closely hardhead conduit and cavity to be connected and to be communicated with main pipe, the main pipe tube wall coats the hardhead surrounding through high-frequency welding, coordinate the most advanced and sophisticated head that after precision die, main pipe and hardhead is combined together, the coating and the fusion molding that are subject to being responsible for wall due to hardhead pipe position are most advanced and sophisticated, as long as one-shot forming just can realize, technique is simple, and by the most advanced and sophisticated hardhead difficult drop-off after supervisor's wall coating melting, safe and reliable.
Beneficial effect: compared with prior art, just can realize the requirement of hardened sharp tip head interposing catheter as long as this utility model is extruded two conduits through high-frequency welding, can realize the requirement that operation process is free from risk again simultaneously.And technique is simple, and is easy to use.This shows, this utility model has reduced greatly production cost, has affected without any step or gap after having avoided again medical-risk, conduit described in the utility model to enter human body simultaneously, guarantees to advance smooth and easy, can avoid most advanced and sophisticated hardhead obscission fully, solve existing medical potential problem.Reduced operation risk and expense, manufacturing process is simple simultaneously. as long as a mold just can satisfy the making of supervisor and hardhead, reduced greatly manufacturing cost.
Description of drawings
Fig. 1 is the structural representation before this utility model welding;
Fig. 2 is the structural representation after this utility model welding.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model specific embodiment is described in detail:
A kind of hardened sharp tip head interposing catheter as shown in Figure 1, comprise a main pipe 1 and the most advanced and sophisticated hardhead 2 shorter than main pipe 1 and hardness ratio main pipe 1 is large, most advanced and sophisticated hardhead 2 closely is socketed in an end of main pipe 1 inner chamber 3, main pipe 1 and most advanced and sophisticated hardhead 2 through most advanced and sophisticated mould high-frequency welding together, main pipe 1 is single chamber or multi-lumen tube.
A kind of intervention catheter manufacture method of head hardened sharp tip head comprises: pass through by composite high-molecular material single chamber or the multi-cavity main pipe 1 that Precise Extrusion is made, than being responsible for the most advanced and sophisticated hardhead 2 of slightly hard composite high-molecular material through Precise Extrusion precision-fit inner chamber, most advanced and sophisticated hardhead 2 is placed on the head position of main pipe 1 inner chamber 3, make main pipe 1 and 2 weldings of most advanced and sophisticated hardhead and most advanced and sophisticated molding through the most advanced and sophisticated mould high-frequency welding of precision, and be communicated with.
Produced conduit has safe and reliable, and production technology is simple, has not only solved the risk that the operation process head comes off. but also reduced greatly manufacturing cost.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
