Patent ID: 8226564

Claim:
A handpiece for ultrasonic electro-medical apparatuses comprising: a grip, for holding the handpiece, said grip consisting of at least two portions, namely a first portion ( 3 ) and a second portion ( 30 ) threadably coupled removably to each other with a screw connection; an operating tip, for performing a treatment on a patient, said operating tip being connected to said grip; first electric terminals and first fluidic terminals provided in said first portion ( 3 ) and second electric terminals and second fluidic terminals provided in said second portion ( 30 ), respectively for coupling together for supplying power to an ultrasonic transducer cooperating with the operating tip, and for supplying a sterile liquid to be sprayed on a patient's operation area; a tubular element ( 6 ), freely rotatably mounted within one of said first and second portions ( 3 , 30 ), said tubular element having a head carrying said fluid terminals ( 4 ) and electric terminals ( 5 ) of said one of said first and second portions, so that said tubular element containing portion is freely rotatable with respect to the tubular element ( 6 ) and said tubular element containing portion can be rotatably disconnected from the non-tubular element containing portion while said fluid terminals and electric terminals contained within said head of said tubular element remain aligned with the fluid terminals and electric terminals provided in the non-tubular element containing portion wherein said tubular element containing portion has axial abutment means for limiting axial movement of said tubular element ( 6 ); and, wherein said abutment means include at least one ring-like shoulder ( 7 ), which is formed by an inner stepped area provided in the tubular element containing portion and against which said tubular element ( 6 ) goes in abutment axially.
