Abstract
The utility model relates to a stone breaker electrode assembled and disassembled in a reflection cup cavity, and an operator does not need to go under the reflection cup when the stone breaker electrode is assembled and disassembled. The electrode consists of an electrically conductive cylinder, threads on the electrically conductive cylinder, a sealing ring, a stainless steel wire, an insulation layer, a positive electrode and a negative electrode. When the stone breaker electrode is used, the electrode is screwed into the reflection cup from the inner part of the cavity of the reflection cup, a shell of the electrode can be reliably contacted with a shell of the reflection cup, a high-voltage cable does not need to be disassembled repeatedly, and the looseness of the electrode and the high-voltage cable is completely avoided. An experiment proves that when the electrode with the structure is used, the electrically conductive cylinder and the reflection cup of the electrode can not have corona ablation, the high-voltage cable does not have abnormal electric discharge, so the treatment effect is obviously improved, and the equipment failure rate is significantly reduced.
Description
Technical field
This utility model relates to the high-voltage discharging electrode that uses on the extra chock wave lithotriptor.The lithotrite electrode is the critical component on the lithotrite, and the discharging gap of electrode discharges in water-filled reflector, produces shock wave, pulverizes the intravital calculus of people.Electrode is the life-span part, and patient of every clinically treatment just needs to change an electrode.Therefore, the basic demand to the lithotrite electrode is: discharge stability, easy to loading and unloading, can not leak.
Background technology
In the present lithotrite, electrode loads and unloads outside the lowermost chamber of reflector, the great advantage of this structure be the electrode volume can do smaller, but through for many years clinical practice, find that there is serious defective in this structure.The first, operator need bend over to get into loading and unloading electrode and high tension cable below the reflector, and it is very inconvenient to operate.Second, since the rubber seal on the electrode make electrode shell can not with the reliable and effective electrically conducting of the shell of reflector, produce violent vibration during simultaneously owing to electrode work discharge, make the high tension cable of electrode and connection electrode occur loosening, thereby produce high tension cable and electrode loose contact, these two kinds of reasons all cause in the place of reflector handling hole corona taking place and ablate, make handling hole increasing, not only have a strong impact on therapeutic effect, and cause seal failure and leak, expensive reflector has to scrap.If getting loose appears in high tension cable, will produce the paradoxical discharge sparking, burn complete machine.Above-mentioned fault is the most frequent fault of present lithotrite.
The utility model content
The purpose of this utility model provides a kind of from the installation of reflector intracavity, working stability, conduction electrode reliable and easy to loading and unloading.
Solution of the present utility model is: 1, on the conductive tube screw thread is arranged, by screw thread, electrode and reflector are fastening, and electrode can not get loose.2, the upper end diameter of conductive tube has sealing ring greater than lower end diameter on the conductive tube, and sealing surface is in reflector inside; So can be from the intracavity loading and unloading electrode of reflector.Insulating barrier is arranged in the conductive tube, and the positive pole of electrode is in insulating barrier inside.3, owing to during each loading and unloading electrode, need not to load and unload high tension cable, so high tension cable is difficult for loosening and damages.
Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing embodiment is described further.
1 is screw thread on the conductive tube among Fig. 1, and conductive tube 2 is exactly the external conductive casing of electrode, tightens electrode from the intracavity of reflector by screw thread.Sealing surface is positioned at the reflector inner surface, and the water in 3 pairs of reflectors of sealing ring plays sealing function.Stainless steel silk 4 welds with conductive tube 1 on one side, and the negative pole 7 of another side and electrode welds, and has guaranteed the reliable conduction of electrode negative pole 7, conductive tube 1 and reflector.Insulating barrier 5 comes the positive pole 6 of electrode and negative pole 7 insulation.The positive pole 6 of electrode links to each other with high tension cable inner wire outside the reflector chamber.Because the loading and unloading electrode is a top-operation just outside the chamber of reflector, so the operator do not need to get into below the reflector, and is easy to operate.The negative pole of electrode links by screw thread and reflector, loosening or the phenomenon that gets loose can not occur.Corona can not appear in reflector ablates, thereby the life-span can be longer.Therapeutic effect can be better.
