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
The present invention relates to a kind of interposing catheter, particularly relate 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 the 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 to make first main pipe substantially, and then the injection moulding hardhead carries out main pipe bonding with glue again.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, cause easily 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.
Summary of the invention
Goal of the invention: the invention solves the deficiencies in the prior art, provide a kind of safe and reliable. the simple hardened sharp tip head of production technology interposing catheter.
Technical scheme: for achieving the above object, the present invention adopts following technical scheme:
A kind of hardened sharp tip head interposing catheter, comprise a main pipe and one than main pipe the short and large most advanced and sophisticated hardhead of hardness ratio main pipe, 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 of the present invention, by an available different hardness, the main pipe that unlike material is made, cooperate with main pipe closely than slightly hard (hardness is adjustable) of main pipe through the conduit of special dies by high-frequency welding and molding by one again, 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 cooperates very closely hardhead conduit and cavity to be connected and to be communicated with main pipe, the main pipe tube wall coats hardhead all around through high-frequency welding, cooperate the most advanced and sophisticated head that behind the precision die main pipe and hardhead is combined together, because hardhead pipe position is subject to being responsible for coating and the fusion molding tip of wall, 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 the present invention extrudes 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, the present invention has reduced greatly production cost, has affected without any step or slit after having avoided again medical-risk, conduit of the present invention to enter human body simultaneously, and it is smooth and easy to guarantee to advance, 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 the present invention welds;
Fig. 2 is the structural representation after the present invention welds.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the invention is described in detail:
A kind of hardened sharp tip head interposing catheter as shown in Figure 1, comprise a main pipe 1 and one than main pipe 1 the large most advanced and sophisticated hardhead 2 of short and hardness ratio main pipe 1, 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 single chamber or the multi-cavity main pipe 1 that Precise Extrusion is made by composite high-molecular material, 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 only is preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (2)
1. hardened sharp tip head interposing catheter, it is characterized in that: comprise a main pipe and one than main pipe the short and large most advanced and sophisticated hardhead of hardness ratio main pipe, 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.
2. a kind of hardened sharp tip head interposing catheter according to claim 1, it is characterized in that: described main pipe is single chamber or multi-lumen tube.
