Electrolysis means are electrolysed in solion so that implant is freed with push rod.The present invention is avoided using conductive pin as electrode
End injury caused by patient, it is ailing to reduce operation；And form circuit and take short and stablize, improve implant frees effect
Rate；Conductive pin need not be additionally used at the same time, also makes operation more simplified.
Foregoing description is only the description to present pre-ferred embodiments, not to any restriction of the scope of the invention, this hair
Any change, the modification that the those of ordinary skill in bright field does according to the disclosure above content, belong to the protection of claims
Scope.
