    摘要： A bipolar electrosurgical tool comprises a retractable cutting element movable along a cutting path and an electrical energy supply source which communicates electrical energy (e.g., radio frequency energy) through one or more energy delivering electrodes associated with a tissue affecting portion of the tool to tissue adjacent the electrodes. One or more additional electrodes, such as return electrodes, form a second pole of the bipolar electrical connection are also associated with the tissue affecting portion and are electrically isolated from the energy delivering electrode. Various combinations of electrically conductive and electrically isolated elements associated with the tissue affecting portion of the device can be used as the two poles of the bipolar system.

    摘要： A biopsy device includes a cannula, a cutter disposed within the cannula, a needle hub having a gear for rotating the cannula, a mechanism for rotating and translating the cutter within the cannula, and a body portion. The cutter rotation and translation mechanism includes a first component that is secured to the cutter and a second component that is secured to the body portion. The body portion includes a tab that is configured to retain the axial position of the cannula and needle hub relative to the body until the tab is depressed or removed. The body is configured to permit the cannula and the needle hub to be pulled axially from the body only after the tab has been depressed or removed. The cutter can then be pulled axially from the body by unscrewing the first component of the cutter rotation and translation mechanism from the second component.

    摘要： An articulating surgical instrument with an articulation transmission assembly for remotely articulating the end effector of the instrument includes a body with a housing mounted on the instrument, oscillating and rotating members, and an actuator rotatably mounted on the housing and secured to the rotating member. The oscillating member is seated rotationally stationary within the housing. The rotating member fits into the oscillating member, and has a drive shaft extending into the body for translating rotation from the rotating member into reciprocation of an elongated transmission rod attached to the drive shaft. First and second sets of unloading teeth are displayed on the oscillating member and actuator, respectively. First and second locking teeth are displayed on the oscillating and rotating members, respectively. The assembly provides ratcheting rotation for precisely positioning the end effector in discrete positions. In the preferred embodiment, the frictional forces between the unloading teeth are less than those between the locking teeth. The instrument may be used for endoscopic as well as conventional open surgical procedures.

    摘要： A surgical stapler instrument is provided for applying lateral lines of staples to tissue while cutting the tissue between those staple lines. The instrument includes a handle portion, an implement portion, a reciprocating section, a drive member and a movable actuator. The implement portion includes a staple cartridge and an anvil. The reciprocating section is adapted to move back and forth along an axis of the implement portion. The movable actuator is associated with the handle portion and is engaged with the drive member such that motion of the actuator causes the drive member to move back and forth between first and second drive positions separated by a first distance. A multiplier is further provided and is associated with the reciprocating section and the drive member for causing the reciprocating section to move back and forth between first and second reciprocating positions in response to movement of the drive member. The reciprocating section includes a work portion which, when moved distally, effects the firing of staples in the staple cartridge toward the anvil. The work portion is also provided with a reciprocating knife. The first and second reciprocating positions are separated by a second distance which differs from the first distance.

    摘要： A biopsy device includes a body, a needle, and a cutter. A motor is operable to both move the cutter relative to the needle and actuate a needle firing assembly to retract and fire the needle relative to the body. The biopsy device also includes a needle rotation assembly that is configured to substantially prevent rotation of the needle about the longitudinal axis when the needle is in a proximal position yet permit rotation of the needle about the longitudinal axis when the needle is in a distal position. A valve assembly of the biopsy device includes a slider that selectively couples a secondary lumen in the needle with either atmospheric air or saline based on the longitudinal position of the slider. The cutter passes through the slider.
