Abstract: A surgical instrument includes a handle portion; an elongated shaft extending from the handle portion to a distal side; an end effector; and an joint assembly, a articulating mechanism and a lockout assembly, the lockout assembly comprises a first lock member and a second lock member, the first lock member is operated to selectively lock a bending operation of the articulating mechanism, and the first lock member is arranged to selectively lock the bending operation of the articulating mechanism under an operation of the articulating mechanism; and the second lock member is arranged to selectively lock a position of the joint assembly under an operation of the handle portion.

Abstract: A surgical instrument and a battery pack for use with the surgical instrument are disclosed. The surgical instrument includes a handle assembly, having a protruding portion; and a battery pack, detachably assembled on the handle assembly, operated by the protruding portion, and having a battery unit, where the battery pack includes a discharging system comprising a discharge element, and a switching member, operated to electrically connect the discharge element to the battery unit of the battery pack to form a discharge circuit, and having an initial open state, in which the discharge circuit is non-conductive, an intermediate open state, in which the switching member cooperates with the protruding portion to make the discharge circuit non-conductive, and a closed state, in which the switching member is separated from the protruding portion to make the discharge circuit conducting.

Abstract: The present disclosure relates to the technical field of medical instrument, and in particular to a surgical instrument and a battery pack for use with the surgical instrument. The surgical instrument, comprises a handle assembly, having a protruding portion; and a battery pack, detachably assembled on the handle assembly, operated by the protruding portion, and having at least one battery unit, wherein the battery pack comprises at least one discharging system comprising a discharge element, and a switching member, operated to electrically connect the discharge element to the battery unit of the battery pack to form a discharge circuit, and having an initial open state, in which the discharge circuit is non-conductive, an intermediate open state, in which the switching member cooperates with the protruding portion to make the discharge circuit non-conductive, and a closed state, in which the switching member is separated from the protruding portion to make the discharge circuit conducting.
