Medical inserting apparatus

A medical inserting apparatus comprising:

• a screw nail which is configured to be inserted into a human body;
• a driver which is configured to insert the screw nail into the human body, the driver having:
• a current generator generating a predetermined current, and
• a current meter measuring the current;
• and
• a conductor located within the screw nail and the driver, elongated along a lengthwise direction, and including an exposed portion which is exposed to outside,
• wherein the conductor includes a forward conductor and a reverse conductor, wherein the forward conductor is coupled to the current generator to allow the current generated by the current generator to flow,
• wherein the reverse conductor has one end electrically coupled to the forward conductor and the other end coupled to the current generator, and includes a variable resistor and the current meter installed to allow the current generated by the current generator to flow to the current meter,
• wherein a resistance value of the human body into which the current flowed is calculated through an amount of current measured by the current meter and a resistance value of the variable resistor, and a type of a tissue of the human body is identified by comparing the calculated resistance value and an inherent resistance value of the tissue of the human body, and
• wherein the resistance value of the human body into through the current flowed is calculated by controlling the variable resistor, a ratio of an amount of current returning to the current meter to an amount of current generated from the current generator is managed to be uniform, and the type of the tissue is identified by comparing the calculated resistance value and the inherent resistance value of the tissue.
