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.
摘要翻译：活检装置包括套管，设置在套管内的切割器，具有用于旋转套管的齿轮的针座，用于使套管内的切割器旋转和平移的机构以及主体部分。切割器旋转和平移机构包括固定到切割器的第一部件和固定到主体部分的第二部件。主体部分包括突出部，其被配置为保持插管和针座相对于主体的轴向位置，直到突出部被按压或移除。主体被构造成仅在突出部被压下或移除之后才允许套管和针座从主体轴向拉出。然后可以通过从第二部件旋转切割器旋转和平移机构的第一部件，从而从主体轴向地拉出切割器。

摘要： A delivery device for delivering a plurality of individual surgical fasteners is disclosed. The delivery device has a drive mechanism having a distal and a proximal end, and a first and a second opposing member. The members are moveable proximally and distally with respect to the delivery device, and individually with respect to each other. The device further includes at least one surgical fastener located between the first and the second members. Each of the at least one surgical fasteners has a proximal end and a distal end. The surgical fasteners are preferably made from a superelastic nickel titanium alloy. Additionally an actuator having at least three sequential positions is included. The first position of the actuator is for moving the drive mechanism distally. The second position is for moving the first member proximally to partially deploy the distal end of the fastener. The third position of the actuator is for moving the second member proximally, to fully deploy the distal end of the fastener.

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.
摘要翻译：双极电外科手术工具包括可沿着切割路径移动的可缩回切割元件和电能源，该电能源通过与工具的组织影响部分相关联的一个或多个能量输送电极将电能（例如射频能量）传递到邻近的组织电极。形成双极电连接的第二极的一个或多个附加电极，例如返回电极也与组织影响部分相关联并且与能量输送电极电隔离。可以使用与器件的组织影响部分相关联的导电和电隔离元件的各种组合作为双极系统的两极。

摘要： An air bag module comprises an inflatable air bag, an inflator and a container for housing the inflator and the air bag. The container comprises an elongated reaction canister having a closed housing formed of a U-shaped body with end walls defining a rectangular top gas discharge opening. An air bag deployment chute comprises a rectangular body having a bottom gas transfer opening mating with the canister opening and a top air bag deployment opening. Cooperating flanges on the top side of the canister and on the bottom side of the chute are interengageable upon endwise sliding to assemble the chute to the canister. Surfaces on the chute and canister engage to locate the chute bottom opening in registry with the canister opening. Cooperating tabs on the canister are received in slots formed in the chute upon assembly and are deformed to lock the chute to the canister. The air bag is attached via loops to two rods which are received in closed channels formed by the cooperating flanges to secure the air bag to the module. Surfaces on the chute and canister engage to prevent endwise rod removal. The inflator has a pair of mounting lugs extending from one end and a single lug at the other end. These lugs may be formed on adapter end caps. The lugs are inserted into grooves in the canister end walls and are slid or rotated past spring barriers into mounting apertures where they are retained against removal.

摘要： A lockout mechanism actuable upon the firing of staples in a surgical staple cartridge such that the lockout mechanism prevents the refiring of the spent staple cartridge when the cartridge remains loaded within the surgical stapler. In addition, the lockout mechanism will prevent reloading of a spent staple cartridge within a surgical stapler after the spent staple cartridge has been removed from the surgical stapler.
