Abstract

This utility model discloses a kind of medical wire rod, and which includes a plastic contacts outer tube, multiple wires and a synthetic fibers tensile cord.Wire is located within the contact outer tube.Synthetic fibers tensile cord is located within the contact outer tube.Pull and reverse by tensile cord opposing, to prevent medical broken wires.

Description

Medical wire rod

Technical field

This utility model is related to medical wire rod, particularly a kind of anti-pull electron medical treatment wire rod.

Background technology

Endoscopy surgery is therapeutic modality gradually expanded in recent years, and which is carried out by the affected part that endoscope penetrates patient Operation, therefore carry out by only needing to the wound of incision small range, patient pain can be lowered and accelerate to restore.Endoscope handss The necessary softness of wire rod used by art can pass through the slot of human body, but excessively soft wire rod is easier to fracture, therefore wire rod Improvement be the neck alkali important topic.

In view of this, this utility model is directed to above-mentioned prior art then, and spy concentrates on studies and coordinates the utilization of scientific principle, as possible Above-mentioned problem points are solved, the target of this utility model improvement is become.

Utility model content

The purpose of this utility model is to provide a kind of anti-pull electron medical treatment wire rod.

For achieving the above object, this utility model provides a kind of medical wire rod, and which includes a plastic contacts outer tube, multiple leads Line and a synthetic fibers tensile cord.Wire is located within the contact outer tube.Synthetic fibers tensile cord is located in outside the contact Within pipe.

Medical wire rod of the present utility model, its contact outer tube are made up of polrvinyl chloride.Those wires are led comprising set of number Line and multiple analog conducting wires.Synthetic fibers tensile cord draws (Kevlar) fiber to make by Kev.The group numeral wire is a pair Twisted-pair feeder.This pair of twisted-pair feeder is coated with an aluminium foil sealing coat.Wear within plastic contacts outer tube and be equipped with aluminum braiding inner tube, and should A little wires and the tensile cord are located in the aluminum braiding inner tube.

Medical wire rod of the present utility model, the contact outer tube of its polrvinyl chloride can reduce affected part contact contact outer tube and Cause the probability of untoward reaction, and be easy to penetrate affected part.Furthermore, by tensile cord opposing pull and reverses be prevented from cure Treat wire rod to rupture in operation.

This utility model is described in detail below in conjunction with the drawings and specific embodiments, but not as to this utility model Restriction.

Specific embodiment

Refering to Fig. 1, preferred embodiment of the present utility model provides a kind of medical wire rod, and which is used for into the affected part for penetrating human body With inspection or operative treatment affected part.Medical wire rod of the present utility model includes a plastic contacts outer tube 100, multiple wires 200 and at least one synthetic fibers tensile cord 300.

In the present embodiment, contact outer tube 100 is soft made by polrvinyl chloride (Poly Vinyl Chloride, PVC) Body, then wears within plastic contacts outer tube 100 and is equipped with aluminum braiding inner tube 110.Therefore when medical wire rod penetrates affected part, energy Enough reduce affected part contact contact outer tube 100 and cause the probability of untoward reaction (such as poisoning, allergy or infection).

Those wires 200 include set of number wire 210 and multiple analog conducting wires 220.The line footpath of each wire 200 is 38AWG, and each wire 200 respectively include a metal conductor wire core 211/221 and be coated on conductor wire core 211/221 it An outer insulation sheath 212/222.Those wires 200 are located within aluminum braiding inner tube 110, therefore, it is possible to by aluminum braiding Pipe 110 isolates external interference signal.The group numeral wire 210 is preferably a pair, and this pair of digital wire 210 is mutual Link and constitute a twisted-pair feeder 201 (Twist-Pair), twisted-pair feeder 201 is coated with an aluminium foil sealing coat 230, therefore, it is possible to borrow Prevent digital wire 210 from interfering with analog conducting wire 220 by aluminium foil sealing coat 230.

In the present embodiment, medical wire rod of the present utility model preferably includes a pair of construction identical tensile cords 300. This pair of tensile cord 300 is located within contact outer tube 100, and each tensile cord 300 is that Kevlar (translate by Chinese：Kev drawing, Kevlar, Kev Le, Kai Kule, time dragon etc.) braiding of shellproof synthetic fibers makes.Therefore, it is possible to pullling and turn round by the opposing of tensile cord 300 Turn, to prevent medical broken wires within affected part.

Certainly, this utility model can also have other various embodiments, spiritual and its essence without departing substantially from this utility model In the case of, those of ordinary skill in the art can make various corresponding changes and deformation, but these phases according to this utility model The change and deformation answered should all belong to this utility model scope of the claims.
