Robotic surgical system for laparoscopic surgery
First Claim
1. A robotic surgical system for performing a surgical procedure on a patient, comprising:
- a master manipulator installed at a control station to be manipulated by an operator;
a plurality of slave robotic units for conducting the surgical procedure;
a control system for electrically associating the master manipulator with the slave robotic units to allow each of the slave robotic units to be remotely controlled by the associated master manipulator; and
a display for viewing the surgical procedure,wherein said each of the slave robotic units includes;
a forearm uniquely provided to said each of the slave robotic units;
a surgical instrument for being inserted to a surgical site of the patient, the surgical instrument being held by the forearm and including a rod and an end tip tool pivotably connected to one end of the rod;
a yaw driving mechanism for moving the rod of the surgical instrument in a yaw direction, the yaw driving mechanism including a wrist coupled to the forearm and rotationally driven in the yaw direction;
a pitch driving mechanism for moving the rod of the surgical instrument in a pitch direction, the pitch driving mechanism including a semicircular rack gear guide supported by the wrist and further including a carriage movably mounted on the semicircular rack gear guide;
a linear driving mechanism for linearly moving the rod of the surgical instrument, the linear driving mechanism being disposed on the carriage;
a rotational driving mechanism for rotating the rod of the surgical instrument about a longitudinal axis of the rod, the rotational driving mechanism being disposed on the carriage; and
a pivotal mechanism for allowing the rod of the surgical instrument to be freely pivoted, the pivotal mechanism being disposed on the carriage.

Abstract
A robotic surgical system includes a master manipulator, slave robotic units having a surgical instrument for performing a Minimal Invasive Surgery (MIS), and a control system for electrically associating the master manipulator with the slave robotic units. The slave robotic unit includes the driving mechanisms which are more compact than those of the conventional MIS system. In use, the existing surgical instruments used in the conventional MIS procedure can be applied to the slave robotic unit. Moreover, by using the pivotal mechanism of the driving mechanisms, a pivot point of the surgical instrument is allowed to be shifted with respect to an incision of a patient. So, the patient'"'"'s tissues surrounding the surgical instrument are not excessively affected by the surgical instrument during the procedure.
