Endoscope manipulator for MIS can overcome disadvantages of multiaxial endoscope manipulator including conventional robot arm and provide compact and lightweight structure to obtain maximum activity space for medical staff. According to the endoscope manipulator for MIS, multi-joint arm is configured so that movement of all of the joints from base link to tip link is manually locked and unlocked by user and not controlled by motors. Additionally, endoscope mounted on an end of multi-joint arm is manipulated using motors to enable movement of three degrees of freedom, thereby accomplishing compact and lightweight endoscope manipulator. Additionally, tube of endoscope can be press-fitted onto tip part of multi-joint arm, and triaxial movement function for vertical, horizontal and forward/backward conveyance of endoscope is implemented in the tip part of multi-joint arm. Therefore, since external manual joints are not moved during operation, Disturbance or restriction to activities of medical staff can be minimized.

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.

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.
摘要:
Nonvolatile memory cells having a split gate structure and methods of fabricating the same are provided. The nonvolatile memory cells include active regions defined at a predetermined region of a semiconductor substrate. A portion of each of the active regions is etched to form a cell trench region. Insulated floating gates are disposed on a pair of sidewalls parallel with the direction that crosses the active region. A source region is disposed at a bottom surface of the cell trench region. A gap region between the floating gates is filled with a common source line electrically connected to the source region. The common source line is extended along the direction that crosses the active regions. The active regions, which are adjacent to the floating gates, are covered with word lines parallel with the common source line. Drain regions are disposed in the active regions adjacent to the word lines. The drain regions are electrically connected to bit lines that cross over the word lines.

Disclosed are a dust receptacle fixing/separating apparatus that fixes and separates a dust receptacle with respect to a cyclone unit, and a cyclone dust collecting device having the same. The dust receptacle fixing/separating apparatus comprises a fixing/separating handle, a locking/unlocking part, and a fixing part. The fixing/separating handle pivots between a first position and a second position, the first position in which the cyclone unit and the dust receptacle are fixed to each other and the second position in which the cyclone unit and the dust receptacle can be separated from each other. The locking/unlocking part fixes and releases the fixing/separating handle when the fixing/separating handle is in the first position. The fixing part pivotably mounting the fixing/separating handle releases connection between the cyclone unit and the dust receptacle when the fixing/separating handle is in the second position.
