Patent number: 8702748Abstract: A laparoscopic surgical instrument includes a shaft and a head having a distal end to which a variety of surgical instruments are attached. The laparoscopic surgical instrument also includes a flexible joint installed between the shaft and the head; a longitudinal-driving unit including a longitudinal-driving wire connected with both longitudinal ends of the head and a longitudinal-driving roller turning the longitudinal-driving wire and a transverse-driving unit including a transverse-driving wire connected with both transverse ends of the head and a transverse-driving roller turning the transverse-driving wire. The longitudinal-driving unit turns the flexible joint in the longitudinal direction, the transverse-driving unit turns the flexible joint in the transverse direction, and the shaft has a small diameter.Type: GrantFiled: October 16, 2008Date of Patent: April 22, 2014Assignee: National Cancer CenterInventors: Dong Jun Kim, Jun Woo Park, Yung Ho Jo

Patent number: 8460175Abstract: According to endoscope manipulator for MIS capable of overcoming disadvantages of multiaxial endoscope manipulator including conventional robot arm and providing compact and light-weight structure to obtain maximum activity space for medical staff, multi-joint arm is configured so that movement of all joints from base link to tip link is manually locked-unlocked by user and not controlled by motors. Endoscope mounted on end of multi-joint arm is manipulated using motors to enable movement of three-degrees of freedom, thereby accomplishing compact and light-weight endoscope manipulator. Tube of endoscope can be press-fitted onto tip of multi-joint arm, and three-axis movement function for vertical, lateral and forward/backward conveyance of endoscope is implemented in tip of multi-joint arm. Since external manual joints are not moved during operation, disturbance or restriction to activities of medical staff can be minimized.Type: GrantFiled: October 23, 2009Date of Patent: June 11, 2013Assignee: National Cancer CenterInventors: Yung-Ho Jo, Kwang-Gi Kim, Kyoung-Won Nam, Young-Woo Kim

Patent number: 8319125Abstract: A pedal input device includes a base plate; a rotation center portion provided at the center of the base plate; a contacting plate having a yaw switch contacting portion protruding downwards from lower surface of the contacting plate; a pedal plate carried by the contacting plate and foot-operated so as to cause a drive member to make three-degree-of-freedom movement; a pair of pitch switches installed on the base plate in an opposing relationship with each other; a pair of roll switches installed on the base plate in an perpendicular relationship to the pitch switches so that the roll switches can be alternately contacted to the contacting plate of the pedal plate; and a pair of yaw switches installed on the base plate in an spaced-apart relationship with each other so that the yaw switches can be alternately contacted to the yaw switch contacting portion as the pedal plate rotates.Type: GrantFiled: July 16, 2009Date of Patent: November 27, 2012Assignee: National Cancer CenterInventors: Yung Ho Jo, Du-Jin Bach, Hye Won Im, Young Woo Kim

Patent number: 8231610Abstract: 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.Type: GrantFiled: September 6, 2006Date of Patent: July 31, 2012Assignee: National Cancer CenterInventors: Yung-Ho Jo, Dong-Jun Kim, Jaesoon Choi, Jae-Gahb Park, Young-Woo Kim, Sang-Jae Park
