Claim 0:
1. An instrument (10) configured to prepare and safely place an intra-uterine device in uterus (50) of a woman, the instrument (10) comprising a “T” shaped intra-uterine device (IUD) (30) with both arms (34) foldable away from a stem (33) of the IUD (30),
a graduated tube (16), a push rod (17) inside the graduated tube (16), wherein the instrument (10) further comprises:
a dynamic stopper (20) with a tubular channel (22) and a flange (25), wherein a sliding length (23) of the dynamic stopper (20) is commensurate with an arm length (38) of the arms (34) of the IUD (30);
a string management arrangement (110) whereby a string (31) of the IUD (30) is in one of a locked condition or an unlocked condition; and
an operating device (100), further comprising
a base (70) having an array of continuous inclines and notches (82) alternately for a prescribed length (83), a plurality of cover engagement means (74), a tube
guideway (84), a first flange guiding projections (72), a carrier guiding projections (73),

a cover (90) having a slot (91), a plurality of base engagement means (94) equal in number of the cover engagement means (74), a knob (150), a knob markings (95),
a carriage (140) having a travel slot (143), at least a pair of locking tooth (148) on either carrier side, a pushrod passageway (147) with a seat (146),
an operating knob (150) having at least a pointer (158), a hanging tubular construction (152) with a larger diameter part (153) along with a pusher (156) and a smaller diameter part (154);

wherein,
the pushrod (17) has a collar (18) and a reversibly collapsible fitment means (19) at an operator end (6) and a flat surface (13) at an IUD end (5), and
the graduated tube (16) having an edge (11) at the IUD end (5), a measurement markings (14) and a string exit slot (15);
wherein,
the dynamic stopper (20) slidably resides in the base (70) and can slide by the sliding length (23), an operator end (6) of the graduated tube (16) is slid through the tubular channel (22) of the dynamic stopper (20), till the operator end (6) of the graduated tube (16) is disposed firmly in the larger diameter part (153) of the knob (150), the dynamic stopper (20) rides on the graduated tube (16), the hanging tubular construction (152) of knob (150) resides in the travel slot (143) of the carrier (140), the push rod (17) resides inside the graduated tube (16) with the reversibly collapsible fitment means (19) of the pushrod (17) pushed in the pushrod passageway (147) such that the collar (18) of the pushrod (17) sits in the seat (146) of the carrier (140); and
when the knob (150) is made to slide towards the IUD end (5), the graduated tube (16) and the dynamic stopper (20) also travel towards the IUD end (5), the dynamic stopper (20) travels by the sliding length (23) while the graduated tube (16) engulfs the arms of the IUD till the edge (11) of the graduated tube (16) is stopped by the dome shaped ends (36) of the arms (34) while the string
(31) remains in the locked condition, a further sliding of the knob (150) towards the IUD end (5) causes the carrier (140) to also move towards the IUD end (5), the pushrod (17) correspondingly moves while the string (31) is in the unlocked condition, a forward and a backward movement of the operating knob (150) by a sliding force on a thumb surface (159), the instrument (10) configured for a single hand grip as well as configured to move the knob (150) by a thumb of the same hand.
