Universal mechanical dilator combined with massaging action

A universal mechanical dilator combined with massaging action comprising:

• a probe consisting of a first rod and a second rod, said first rod having a distal end and a proximal end, said second rod having a distal end and a proximal end;
• a reciprocating drive unit having a first drive member and a second drive member, said first drive member and said second drive member reciprocating with respect to each other simultaneously and in mutually opposite directions;
• a tubular adapter between said probe and said drive unit, said adapter having a front end and a rear end, said front end of said adapter having a female thread, said proximal end of said first rod is larger in its cross section than a cross section of said second rod and has a through central opening extending in a longitudinal direction of said probe and slidingly receiving said second rod, said second rod passing through said central opening and through said adapter to said drive unit;
• said proximal end of said first rod having a male thread engaging said female thread on said front end of said adapter;
• said first drive member having a threaded projection, said proximal end of said second rod having a threaded opening which receives said threaded projection screwed into it for rigidly connecting said second rod to said first drive member;
• said rear end of said adapter supporting means for releasably connecting said adapter to said second drive member and said second rod having means for engaging with said means for releasably connecting said adapter when said adapter is disconnected from said second drive member;
• said probe having a straight portion which is slidingly received in said through opening and a bent portion which is arranged at an angle to said longitudinal direction and which is formed by said distal end of said first rod and said distal end of said second rod.
