    摘要： Apparatus including a frame; a generally elongated endoscopic portion connected to the frame and extending distally therefrom; a pair of jaw members cooperating with a distal end of the endoscopic portion, the jaw members disposed in opposing relation and being relatively pivotal about a common point between at least an open position and a closed position, each of the jaw members including: a distal portion including a first surface adapted for engaging tissue, the first surface having a recessed portion formed therein and a second surface being of smooth continuous construction; a proximal portion including pivot means adapted to cooperate with the inner rod member; and an intermediate portion being recessed relative to the distal portion such that upon contact of the jaw members, the intermediate portions are spaced apart from each other. The apparatus may further comprise means for rotating the endoscopic portion. In a preferred embodiment, the apparatus is a unipolar electrosurgical biopsy forceps and is provided with conducting means attachable to the frame and in electrical communication with a conductive endoscopic portion for receiving an electrical current from an electrical source. The jaw members are also electrically conductive. Electrical insulating means may be selectively disposed on the instrument for insulating predetermined portions thereof from electrical energy.

    摘要： An endoscopic or laparoscopic surgical instrument having an internally disposed locking mechanism located within a barrel portion of a handle assembly. The instrument includes a handle assembly having a pivoting handle and a stationary handle, a barrel portion to which an elongated body assembly is secured, and a locking mechanism for releasably positioning a tool mechanism located at the distal end of the body assembly. In one embodiment the locking mechanism comprises a trigger, a brake and a latch spring. In another embodiment the locking mechanism comprises a latch spring and a locking block. A rotational knob and locking member may also be provided to position the body assembly at various orientations to the longitudinal axis.

    摘要： The present invention, in accordance with various embodiments thereof, relates to a surgical device for at least one of cutting and stapling a section of tissue. The surgical device includes a housing including at least two drivers. The surgical device also includes an anvil mechanically attachable to the housing and moveable relative to the housing between an open position and a closed position. The first driver operates to move the anvil relative to the housing to an intermediate position between the open position and the closed position. The second driver operates to move at least a portion of the housing relative to the anvil between the intermediate position and the closed position.
