Patent number: 8688195Abstract: Provided is a fluorescent indication clip for surgery that has an improved function as a position indicator due to a photo-reactive fluorescent material included in the bio-clip, and allows people to rapidly and easily detect the accurate position of an internal operation region, and thus can improve operation accuracy and reduce side effects caused by excessive incision. The fluorescent indication clip includes a self-spreadable clip body, a fluorescent indicator prepared at the rear end of the clip body and including a photo-reactive fluorescent material, and a clamper configured to slide from a position at which the clamper is mounted on the fluorescent indicator to the clip body by an external force, and fasten the clip body to narrow front ends of the clip body.Type: GrantFiled: November 4, 2009Date of Patent: April 1, 2014Assignee: National Cancer CenterInventors: Dae-Kyung Sohn, Kwang-Gi Kim, Yong-Doo Choi, Kyoung-Won Nam, Hyun-Ho Kim

Patent number: 8475362Abstract: Provided is a surgical apparatus for transanal endoscopic microsurgery (TEM) in which a thin and long endoscope and surgical instruments are inserted through a natural orifice of a human body and the endoscope and surgical instruments are conveyed to the operation area in the body to perform the operation area in the body. According to the surgical apparatus for TEM, a rotation function is added to a barrel of the surgical apparatus for TEM to enable manual rotation of the barrel to a required extent and adjustment of an operation area, without separation of the surgical apparatus for TEM from a fixing frame during an operation. In addition, since the endoscope is disposed outside the barrel, it is possible to reduce the outer diameter of the barrel and uniformly maintain a visual direction of the endoscope even when the barrel is rotated. Further, since the rotation function is added to both the barrel and the surgical instrument insertion hole, more convenient operation is possible.Type: GrantFiled: March 16, 2010Date of Patent: July 2, 2013Assignee: National Cancer CenterInventors: Dae-Kyung Sohn, Dae-Hyun Kim, Kwang-Gi Kim, Kyoung-Won Nam, Hyung-Tae Kim

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
