Abstract
A kind of download combined electrode of extracorporeal shock-wave lithotripter is composed of the electrode frame, the upper and lower electrodes; the upper electrode 2 is fixed on the top of the frame 1 while the lower electrode 3 is set on the bottom of the frame 1; between the upper and lower electrodes is the discharge clearance, an installing seat 8 is fixed on the bottom of the semi-ellipsoid of wave resources; the upper part of the said electrode frame is a supporting frame 1A fixed with the electrode 2 while the lower part matches the internal hole of the installing seat. The diameter of the upper part is shorter than that of the lower part. The said electrode 2 is fixed on the supporting frame 1A of the top frame through the adjustable screw cap 4. The said electrode 3 is embedded in the center of an insulating set 7; the insulating set 7 is fixed below the frame 1 through the pressing nut 6. The said electrode assembly inserting devices are installed in the said installing seat 8, and are pressed in the installing seat through the cap 9. The utility model is convenient in installation and replacement, and the cost of operating the equipment is lowered.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically refers to the electrode structure of electrohydraulic type extra chock wave lithotriptor, is the improvement to the lithotrite traditional electrode.
Background technology
Now, by widespread usage, wherein most widely used be the electrohydraulic type extra chock wave lithotriptor to extra chock wave lithotriptor aspect the treatment calculosis.The electrohydraulic type shock wave source is mainly by a semielliptical reflector A, electrode assemblies B, reach water pocket and charge and discharge the water system composition, referring to Fig. 2, electrode is positioned at the bottom of described semiellipsoid, on it, bottom electrode opposite position (being point of discharge) just overlaps with first focal point F 1 of described semiellipsoid, when the electrode energized, on, just produce discharge between bottom electrode and form shock wave under water, this shock wave arrives its second focal point F 2 through the inner surface reflect focalization of semiellipsoid, as this moment calculosis just be positioned at this second focus place, will be smashed by the huge energy of shock wave, thereby can excrete more easily, play the effect of treatment calculus.
Present electrohydraulic type extra chock wave lithotriptor with electrode generally as shown in Figure 3, it is made up of top electrode 21, bottom electrode 22, outer casing stand 24 and sealing ring 23.Top electrode 21 directly is welded on the outer casing stand 24 and becomes one with support, and bottom electrode 22 is fixed on the outer casing stand 24 after insulating.The weak point of existing electrode is: upper and lower interelectrode frequent and intensive discharge during owing to work, and upper and lower interelectrode metal is seriously ablated, the guiding discharge gap is strengthened also and is made electrode failure, so can only disposablely use.Behind the electrode failure, entire bracket needs transposing in the lump, and expense is very high, has both wasted resource, has increased use cost again; Simultaneously, need drain the water in the semielliptical reflector during owing to the replacing electrode earlier, pull down water pocket, from the electrode that the opening part taking-up of semiellipsoid has been ablated, new electrode is installed, and then water pocket is installed, program is very loaded down with trivial details, very inconvenience.
Summary of the invention
The purpose of this utility model is to propose a kind of extra chock wave lithotriptor assembly combined electrode down, by existing integral type electrode is improved to combined electrode, and will be improved to the mounting means that inserts from the bottom of semiellipsoid, thereby overcome the deficiencies in the prior art by the mounting means that the semiellipsoid opening part is inserted.
A kind of extra chock wave lithotriptor of the present utility model assembly combined electrode down, mainly comprise an electrode suppor 1, top electrode 2 and bottom electrode 3, top electrode 2 is fixed in the top of support 1, bottom electrode 3 is fixedly arranged on the bottom of support 1, on, bottom electrode relatively and keep a discharging gap, one mount pad 8 that is fixed in the semiellipsoid bottom of wave source is arranged, the top of described electrode suppor 1 is the fixing support 1A of top electrode 2, the endoporus of bottom and described mount pad is complementary, its upper part diameter is less than lower diameter, and formation can be inserted the down-mounting type structure in the mount pad 8 of described semiellipsoid bottom.Described top electrode 2 is regulated nut 4 by one and is fixed on the support 1A on support top.Described bottom electrode 3 is embedded at an insulation sleeve 7 centers, and this insulation sleeve 7 is fixedly arranged on support 1 bottom by a clamp nut 6.Support 2 forms a dismountable type compound electrode with upper and lower electrode 2,3 like this.Electrode assemblies after the described assembling is inserted in the described mount pad 8, and by and medicated cap 9 be pressed in this mount pad.
Advantage of the present utility model is: owing to design its support first half less than Lower Half consciously, therefore assemble the rear electrode assembly and can insert below the bottom of semielliptical reflector, reuse and medicated cap are fixed, and install with replacing very convenient; Owing to be dismountable type between electrode and support, so arbitrary electrode erosion only need be changed this electrode, and electrode suppor still can continue to use, and has both saved social resources, has reduced equipment operating cost again simultaneously.
Description of drawings
Fig. 1 is the structural representation of assembly combined electrode down of the present utility model;
Fig. 2 is a structural representation of the present utility model;
Among the figure: 1 electrode suppor, 2 top electrode assemblies, 3 bottom electrode assemblies, 4 top electrode adjusting nuts, 5 sealing rings, 6 clamp nuts, 7 insulation sleeves, 8 mount pads, 9 and medicated cap.
Fig. 3 is the sketch map of existing electrode.
Embodiment
During use:
The insulation sleeve 7 that a. will be embedded with bottom electrode 3 is earlier inserted in the support by support 1 below, fixing with clamp nut 6, again top electrode 2 is assembled in electrode suppor 1 the support center, regulate upper and lower interelectrode gap, fixing with nut 4 then, form an electrode assemblies;
B need not pull down under the situation of water pocket, drains the water in the semielliptical reflector);
C. unclamp the also medicated cap that compresses electrode assemblies on the mount pad 8, take off old electrode assemblies below the bottom of semielliptical reflector, insert new electrode assemblies, reuse and medicated cap are fixed.
D. the old electrode assemblies that removes is put in order, the upper and lower electrode that changing wherein ablates damages is also adjusted upper and lower interelectrode discharging gap, so that use next time.
