Abstract
The utility model relates to a dismountable electrode for an external vibration wave lithotriptor, which belongs to a medical appliance. A screw rod of a positive electrode of an electrode which is connected with a screw thread is arranged in the core bar of the positive electrode of the electrode, a spring is arranged on the bottom of the screw rod, the core of the positive electrode of the electrode is welded in the upper segment of the spring and the screw rod is in threaded connection with the core bar of the positive electrode. An insulating cushion ring is arranged below a locking nut with a hole and is in threaded connection with the screw rod of the positive electrode; the negative electrode ring of the electrode is connected with the sleeve of the negative electrode of the electrode by screws. The utility model with the structure has the advantages of simple operation for adjusting electrode gap, labor saving, time saving, economy, practicality, etc. Compared with the service life of the existing electrode, the service life of the utility model can be improved by many times and large numbers of materials can be saved.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly extracoporeal shock wave lithotripsy reassembling type electrode.
According to the knowledge of the applicant: the electrode of existing extracoporeal shock wave lithotripsy is because of reasons in structure, discharge between the positive and negative pole piece, makes that the gap constantly increases between the tip, and can not discharge, use several times the positive pole piece in back all to scrap, can not reuse, so service life weak point, material consumption is many, the cost height.
The purpose of this utility model is intended to overcome the shortcoming of above-mentioned prior art, the reassembling type electrode that the source between a kind of electrode designed is adjustable, be convenient to change electrode.
The purpose of this utility model is such realization: comprise by the electrode negative pole core that is installed in the electrode anode core on the electrode anode screw rod and be installed on the electrode negative pole connecting to form.The electrode anode screw rod that is threaded promptly is housed in the electrode anode plug, be equipped with in the screw rod bottom be welded with the electrode anode core in spring, its epimere, this screw rod is threaded with anodal plug, lock nut with holes has insulating washer and is connected with anodal screw flight, and electrode negative pole ring is applied mechanically screw with the electrode negative pole and is connected.
Electrode anode plug and insulation sleeve, insulation sleeve is all used bonding the connection with electrode negative pole cover.
This utility model makes it have electrode gap and adjusts simple to operate, saving of work and time, economical and practical owing to adopt said structure, than improving several times the service life of existing electrode, saves advantages such as wide variety of materials.
Describe in detail below in conjunction with accompanying drawing.
Fig. 1 is this utility model structure cutaway view.
Code name among the figure: 1 electrode anode plug, 2 insulation sleeves, 3 electrode negative poles overlap 4 springs, 5 electrode anode screw rods, 6 insulating washers, 7 lock nuts, 8 electrode negative pole rings, 9 electrode anode cores, 10 electrode negative pole cores, 11 screws.
With reference to Fig. 1, entire electrode comprises by electrode anode plug 1, the insulation sleeve 3 between electrode negative pole cover 2 and their (1,2), and the electrode negative pole core on electrode anode core 9 on the electrode anode plug 1 and the electrode negative pole ring 8 10 is formed.The electrode anode screw rod 5 that is threaded promptly be housed in electrode anode plug 1, in spring 4, its epimere are equipped with in screw rod 5 bottoms, be welded with electrode anode core 9, this screw rod 5 is threaded with anodal plug 1, lock nut 7 with holes has insulating washer 6 and is threaded with anodal screw rod 5, and electrode negative pole ring 8 is connected with electrode negative pole cover 3 usefulness screws 11.The assembly of spring more than 4 can all be dismantled.Because this electrode is to be embedded in the water of certain pressure when work, leak for preventing the electrode place, so during fabrication, and electrode anode plug 1 and insulation sleeve 2, insulation sleeve 2 all adopts bonding agent to link into an integrated entity with electrode negative pole cover 3.
During this utility model work, under high-tension effect, constantly produce spark between electrode anode core 9 and the electrode negative pole core 10, seismic wave takes place, because herein under the High Temperature High Pressure of being everlasting, gap between positive and negative electrode core (9, the 10) tip is constantly increased, so that can not discharge, can't operate as normal.At this moment just need the adjusting play distance.This electrode rotates anodal screw rod 5 and makes positive and negative electrode core (9,10) after normal clearance exactly by unclamping lock nut 7, and lock nut 7 again, can continue operate as normal.In addition,, electrode negative pole ring 8 usefulness screws 11 and electrode negative pole cover 3 are linked together, unclamp screw 11 when changeing, take off electrode negative pole ring 8, can set up a positive pole piece 9 again, just can continue to use in order to change positive electricity pole piece 9 convenience.
Claims (2)
1, a kind of extracoporeal shock wave lithotripsy reassembling type electrode, comprise by the electrode negative pole core that is installed in the electrode anode core on the electrode anode screw rod and be installed on the electrode negative pole ring and connecting to form, it is characterized in that: the electrode anode screw rod that is threaded is housed in the electrode anode plug, be equipped with in the screw rod bottom be welded with the electrode anode core in spring, its epimere, this screw rod is threaded with anodal plug, lock nut with holes has insulating washer and is connected with anodal screw flight, and electrode negative pole ring is applied mechanically screw with the electrode negative pole and is connected.
2, extracoporeal shock wave lithotripsy reassembling type electrode according to claim 1 is characterized in that: electrode anode plug and insulation sleeve, insulation sleeve and electrode negative pole cover are all used bonding connection.
