Claims7
A smog suction structure of an electrosurgical handpiece, the smog structure comprising:
- a case (110);
- a pipe-type inner cylinder (170) inserted into the case (110) and having one side connected to a suction pipe (102) at a rear side of the case (110);
- a pipe-type operating rod (150) comprising an inner cylinder insertion hole (152), which is provided at one end so that the inner cylinder (170) is inserted into the inner cylinder insertion hole (152);
- a connector (154) provided at another end of the operating rod (150) and comprising a plug insertion hole (155) and a suction hole (156) configured to suction smog;
- and
- a conductive electrode (130), which is inserted into the plug insertion hole (155) to be detachable/attachable,
- wherein the smog suction structure is configured such that the smog suctioned into the suction hole (156) does not come into contact with an inner surface of the case (110) and flows inside the operating rod (150) and the inner cylinder (170) so as to be discharged to the suction pipe (102).
