Abstract
The utility model provides a flexible guide electrode used in the internal shock wave stoning machine, the diameter electrode is larger than 0. mm and less than 1.8 mm, and the electrode can be freely bent along the inner lens of the tube and can conduct the shock wave. The electrode consists of a conductor, an insulation layer, an external insulation tube, a metal ring, a hollow core section and a connector. The utility model is novel in structure, easy in manufacture, high in efficiency and reliable in security.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of thin footpath flexible guiding sparking electrode that uses during blast wave stone-breaking in the body.
Technical background:
At present, in human body, utilize hydroelectric shock wave to pulverize the Therapeutic Method of calculi in vivo owing to need that energy is little, calculifragous efficiency is high, by wide clinical application, the sparking electrode that matches is also used in a large number to the human normal tissue damage is little by endoscope.Existing sparking electrode is divided into two types substantially: a kind of is the rigidity electrode, is made of unyielding metal tube and lead; Another kind is a flexible electrode, and being constituted side by side or used coaxial cable, the operation principle of these two kinds of electrodes by the lead of two mutually insulateds all is to insert human body through the treatment hole of endoscope, and electrode end is discharge generation blast wave stone-breaking in the liquid state in vivo.Because the rigidity electrode can not be with the bending of flexible pipe endoscope, clinical use is very limited; And the shock wave radial spread spherical in shape that wire end arranged side by side produces, the energy dispersion efficiency is low; The coaxial cable of present commercially available diameter phi≤1.8mm is because outer conductor all is a woven mesh structure so can not directly use, and reforming technology is complicated, causes cost and price all very high, and is also impracticable.
The content of utility model
The purpose of this utility model provides a kind of novel structure, cost is low, diameter is little, can have guide effect with any bending of flexible pipe endoscope, shock wave, efficiently rubble sparking electrode in the body.
The technical solution that realizes above-mentioned purpose is such:
This sparking electrode is made up of lead, external insulation pipe, becket, hollow section and the joint of the tape insulation layer of two parallel arranged.Said tape insulation layer conductor is an alloy conductor external application plastic layer; Said external insulation pipe is a hollow plastic pipe; Said becket curves ring-type by bare conductor or is made of metal thin tube; Said hollow section is the tape insulation layer conductor to be taken out a section lead form; Said joint is commercially available connector.This utility model novel structure, make simple, can accomplish 0.4mm～1.8mm because of shock wave has guide effect efficient height, diameter, easy manufactured merchant and user accept extensively.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with Fig. 1 this utility model is further described.
As shown in Figure 1, this utility model mainly is made up of conductor 1,2, polyvinyl fluoride insulating barrier 3,4, polyvinyl fluoride external insulation pipe 5, becket 6, hollow section 7 and joint 8.The i.e. tape insulation layer conductor of two parallel arranged, outside cover one deck plastic insulating tube 5 (overall diameter span 0.4mm≤Φ≤1.8mm), lead one end is equipped with two commercially available core joints 8, the wherein lead of the other end and becket 6 joins, another root lead passes from becket 6 and one joint is arranged is that (hollow section span 0.4mm≤L≤2mm), becket 6 is apart from the span 0.2mm≤L≤3mm of hollow section 7 ends for the hollow section 7 of no conductor at the end.
The overall diameter span 0.4mm≤Φ≤1.8mm of becket 6 can form with the bare conductor bending, also can constitute with a trifle metal thin tube.
When implementing treatment, two core joints 8 of sparking electrode connect main frame energy output end, the stone location of other end full of liquid in human body is inserted in the endoscope treatment hole.When applying high electric field pulse, between the end of becket 6 and conductor 2, center on axis discharge generation shock wave, thus crushed stone.
