Embodiment
The embodiments described below with reference to the accompanying drawings are exemplary, is only used for explaining the present invention, and can not be construed to
Limitation of the present invention.
Embodiments of the invention：As shown in Figures 2 and 3, a kind of Novel Bipolar radio frequency plasma knife, including handle, power supply
Line 1, plug 2 and inner core 3, wherein handle include main handle 4 and auxiliary-handle 5, and the upper end of main handle 4 has perpendicular arrangement
Inner core bindiny mechanism 7 is provided with auxiliary-handle connecting pole 6, auxiliary-handle connecting pole 6, one end of auxiliary-handle 5 is connected installed in auxiliary-handle
On post 6, the other end is provided with inner core protection pipe 8, and auxiliary-handle 5 can slide axially on auxiliary-handle connecting pole 6 along it, in auxiliary-handle 5
It is additionally provided with spring 9；Inner core 3 is plugged in inner core protection pipe 8, and its one end is connected with inner core bindiny mechanism 7, and the other end has electrode
51, one end of power line 1 is connected with inner core bindiny mechanism 7, and the other end is connected with plug 2.
In use, being assembled first, spring 9 is loaded in auxiliary-handle 5 first, inner core 3 is then had into electrode 51
One end from the left end of auxiliary-handle 5 insertion inner core protection pipe 8, then by the left end of inner core 3 insert in auxiliary-handle connecting pole 6 and with it is interior
Core bindiny mechanism 7 is docked, and then auxiliary-handle 5 is plugged on auxiliary-handle connecting pole 6, now completes assembling.During operation, by plug
2 are inserted on socket, and electric energy passes to inner core bindiny mechanism 7 by power line 1, and inner core bindiny mechanism 7 passes to inner core 3, made again
The electrode 51 of inner core 3 works.It is a bit of that inner core protection pipe 8 is only stretched out in one end of normal condition bottom electrode 51, when with finger pull
During auxiliary-handle 5, auxiliary-handle 5 is moved to the direction of main handle 4, while compression spring 9, due to not having between inner core 3 and main handle 4
Relative displacement, therefore drive inner core protection pipe 8 to move while the movement of auxiliary-handle 5, inner core 3 then stretches out the portion of inner core protection pipe 8
Divide more and more, it is preferable that the inner core 3 of this case is made of memorial alloy, have the one of electrode 51 under nature on inner core 3
End has a natural torsion, and as inner core 3 stretches out the length increase of inner core protection pipe 8, the natural torsion loses inner core protection
The constraint of pipe 8 then restores to the original state, and as extension elongation increase angle of bend gradually increases, therefore passes through the regulation to auxiliary-handle 5
It can realize and patient's different parts are performed the operation, effectively expand working range.When finger discharges auxiliary-handle 5, in spring 9
In the presence of, auxiliary-handle 5 is moved with inner core protection pipe 8 to the direction away from main handle 4, and inner core 3 gradually protect by retraction inner core
In pipe 8.
Because the auxiliary-handle 5 of the present invention can be dismantled from main handle 4, and inner core 3 also can be dismantled freely, therefore can be real
Existing sufficiently sterilised, in addition it is of the invention it is simple in construction, be easy to assemble and operate.
In addition to being carried out disinfection to the present invention, also auxiliary-handle 5, inner core protection pipe 8 and the inner core 3 of the present invention can be made one
Secondary property part, the part directly more renewed of having performed the operation every time, can equally solve to sterilize halfway problem.If by assistant
Handle 5, inner core protection pipe 8 and inner core 3 make disposable part, and their the main material of casing part is preferably plastics.
It is preferably carried out in one kind in mode, incorporated by reference to such as Fig. 3, Fig. 4, Fig. 5 and Fig. 6, on the basis of above-described embodiment,
