Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
For the internal structure that realizes the electro-medical plug is simple, production cost is lower, avoid potential safety hazard, the embodiment of the invention provides a kind of disposable plug, referring to Fig. 1 and Fig. 5, sees for details hereinafter and describes:
A kind of disposable plug comprises: housing 1, be connected with fixedly inserted link 2 on the housing 1, and fixedly inserted link 2 is connected with the lead of housing 1 inside; Housing 1 inside is provided with the ccontaining cavity 3 of the insulation that has slideway 10, insulating is provided with electroconductive elastic sheet 4 in the ccontaining cavity 3, and an end of electroconductive elastic sheet 4 is connected with conductive slider 5, and conductive slider 5 lower ends contact with inserted link 6, inserted link 6 is provided with protruding block 7, is socketed with spring 8 on the protruding block 7; The side of conductive slider 5 is connected with guide rod 9, motion in the sideslip road 11 that guide rod 9 connects at slideway 10 and with slideway 10.
Wherein, be provided with protruding block 7 by inserted link 6, come the move distance of restricted spring 8, better work in order to make spring 8, the embodiment of the invention preferably is provided with protruding block 7 at the middle part of inserted link 6, and the shape of protruding block 7 is preferably cylindrical.
Further, in order to increase work efficiency, the shape of the conductive slider 5 in the embodiment of the invention is preferably cylindrical.
Wherein, slideway 10 and sideslip road 11 both can be arranged on the left side of the ccontaining cavity 3 of insulation, also can be arranged on the right of the ccontaining cavity 3 of insulation, the embodiment of the invention be with slideway 10 and sideslip road 11 be arranged on the insulation ccontaining cavity 3 the right be that example describes, during specific implementation, the embodiment of the invention does not limit this.
Below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5 the concrete working method of disposable plug is described, sees for details hereinafter and describe:
Referring to Fig. 1, initial condition and position for disposable plug, inserted link 6 contacts with conductive slider 5, conductive slider 5 contacts with electroconductive elastic sheet 4, inserted link 6 is provided with protruding block 7, is socketed with spring 8 on the protruding block 7, and conductive slider 5 can slide in the ccontaining cavity 3 of insulation, conductive slider 5 contacts with electroconductive elastic sheet 4, electroconductive elastic sheet 4 can with the conduction of current of inserted link 6 to lead that plug links to each other in.
Referring to Fig. 2, when disposable plug inserts socket, the resistance that inserted link 6 is stressed to overcome spring 8 moves along the direction of housing 1 inside, guide rod 9 slides in slideway 10, drives conductive slider 5 and moves to top, and electroconductive elastic sheet 4 is subjected to force compresses, inserted link 6 at an end of plug outside with fixedly inserted link 2 is concordant, make disposable plug be in normal conducting state, fixedly inserted link 2 and inserted link 6 are distinguished turning circuits, surgical instrument operate as normal.
Referring to Fig. 3, after surgical instrument is finished using, with disposable plug when socket pulls up, electroconductive elastic sheet 4 bounce-backs, apply a tangential active force (along the active force in sideslip road 11) for conductive slider 5, guide rod 9 approaching side slideways 11, conductive slider 5 under the traction of guide rod 9, enter and the ccontaining cavity 3 of 11 position corresponding insulation that breaks away in, conductive slider 5 separates with inserted link 6, makes disposable plug be in off-state.
Referring to Fig. 4, after disposable plug pulls up from socket, when inserted link 6 moves to bottom at the effect lower edge of spring 8 housing 1 outward direction, conductive slider 5 also enter and the ccontaining cavity 3 of 11 position corresponding insulation that breaks away in, even at this moment more disposable plug is inserted socket, the resistance that inserted link 6 is stressed to overcome spring 8 moves along the direction of housing 1 inside, inserted link 6 can not contact with conductive slider 5, the not conducting of internal circuit of disposable plug, be in off-state, thereby guarantee that disposable plug can only use once.
Wherein, during specific implementation, the embodiment of the invention is not done any restriction to the size of each parts, can design the size of each parts according to the needs in the practical application.
In sum, the embodiment of the invention provides a kind of disposable plug, after plug is extracted from socket, because conductive slider is received the rebound effect of electroconductive elastic sheet, under the traction of guide rod, make conductive slider approaching side slideway, when plug inserts socket once more, because conductive slider is the approaching side slideway, make that the power supply on the inserted link can not conducting, thereby guarantee that plug can only use once, avoided potential safety hazard for this reason; Simultaneously, this plug has been simplified internal structure, need less internal components, so production cost is lower.
It will be appreciated by those skilled in the art that accompanying drawing is the schematic diagram of a preferred embodiment, the invention described above embodiment sequence number is not represented the quality of embodiment just to description.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
