Abstract
A shielding combined electrode used in the extracorporeal shock wave lithotripsy machine, which is mainly composed of an electrode support 1, an upper electrode component 2, a lower electrode component 3 and a lower electrode base 4, while the lower electrode base 4 is fixedly arranged in a semi-ellipsoid 8 on the wave source; the upper electrode component 2 is fixed on the support 1, and the lower electrode component 3 is fixed on the lower electrode base 4; the upper and the lower electrodes are opposite to each other and maintain a discharge gap, while the upper and the lower electrode 2,3 form the combined electrode respectively; the electrode support 1 is provided with a shielding head 7 to hold back the shock wave which is not focused. Through the combined type design, the electrode and the support of the utility model can be detachable, so only the electrode need to be replaced when any electrode ablates. While the electrode support can be used continually, which can not only reduce the operation cost of the equipment, but is also easy to use; at the same time, the shielding head can block the shock wave which is not focused entering the body.
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. 1, 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 2, 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,, make a part of unfocused shock wave directly enter human body, cause the injury certain human body because the shock wave that electrode discharge forms is sphere to space divergence.
Summary of the invention
The purpose of this utility model is to propose the combined electrode of a kind of extra chock wave lithotriptor with the band shielding, by existing integral type electrode is improved to combined electrode, and be provided with one at top electrode and can stop not and to focus on and the shielding head of the shock wave of the human body that can go directly, thereby overcome the deficiencies in the prior art.
A kind of extra chock wave lithotriptor of the present utility model mainly comprises an electrode suppor 1, top electrode assembly 2 and bottom electrode assembly 3 and lower electrode holder 4 with the combined electrode of band shielding, and lower electrode holder 4 is fixedly arranged in the semiellipsoid 8 of wave source; Top electrode assembly 2 is fixed on the support 1, and bottom electrode assembly 3 is fixed in the lower electrode holder 4, and upper and lower electrode is relative and keep a discharging gap, and upper and lower electrode 2,3 forms compound electrode respectively; On electrode suppor 1, be provided with one in order to the shielding of the shock wave that stops not line focus 7.
Advantage of the present utility model is: design by combination type, detachable between electrode and support, so arbitrary electrode erosion only need be changed this electrode, and electrode suppor still can continue to use, both reduced equipment operating cost, convenient again the use, simultaneously, the shielding head can stop that the shock wave of not line focus enters human body.
Description of drawings
Fig. 1 is the structural representation of extra chock wave lithotriptor of the present utility model with the combined electrode of band shielding;
Fig. 2 is the sketch map of existing electrode.
Among the figure: 1 electrode suppor, 2 top electrode assemblies, 3 bottom electrode assemblies, 4 lower electrode holders, the shock wave after 5 focusing, 6 unfocused shock waves, 7 shielding heads, 8 semiellipsoids, 9 second focuses.
Embodiment
In actual use, lower electrode holder 4 is fixed on the semiellipsoid 8, does not need dismounting.
A is assembled into top electrode assembly 1 on the electrode suppor 2;
B installs to bottom electrode assembly 3 on the lower electrode holder 4;
C is installed to the assembly of top electrode assembly 2 with electrode suppor 1 on the lower electrode holder 4, finishes electrode and installs;
D installs other rubble preparations such as water pocket, water-filling, aerofluxus again in semiellipsoid 8.
