Abstract: A medical anastomosis apparatus is provided. The medical anastomosis apparatus includes a cylindrical body which has a hollow portion and extends in a longitudinal direction, a pressing rod which is provided inside of the hollow portion of the body to translate along the hollow portion, a knob which is coupled to the pressing rod to provide a driving force to translate the pressing rod, a guide member which is inserted into one end of the body and simultaneously coupled to expose a portion of the body and has a pressing unit formed therein to move radially upon translation of the pressing rod, and a staple cartridge which is inserted around an outer circumferential surface of the guide member and then coupled to the body and has built-in staple clips that protrude outward upon movement of the pressing unit.

Abstract: 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.

Abstract: There is provided a bearingless step motor in which a rotating shaft can rotate while rising from a main body by a magnetic force without using a mechanical bearing. The bearingless step motor comprises a stator including stator cores having winding portions and a rotor including a rotating shaft and rotor cores. The rotor rotates by a magnetic interaction between the rotor cores and the stator cores. A first permanent magnet is mounted to the rotor and a second permanent magnet is mounted to the stator. The first permanent magnet and the second permanent magnet are arranged so that a repulsive force is generated between magnetic poles. There is little power consumption for raising the rotating shaft and a complicated system for controlling the rise of the rotating shaft is unnecessary. Thus, the motor can be manufactured with a light and compact structure.
