摘要： An electrosurgical stapling instrument includes an end effector capable of applying bipolar RF energy into tissue. The end effector has a first pole electrode and a second pole electrode for forming an RF contact circuit with tissue. At least one of the electrodes may have a dielectric coating thereon to create a RF circuit with tissue. The dielectric coating can cover one of the electrodes to create a capacitive coupling circuit with tissue, or can have at least one open passageway extending through the dielectric coating to enable tissue contact with the electrode and the passage of RF energy therethrough. The dielectric coating on the electrode can be masked to create passageways through the dielectric, or the dielectric coating can be locally removed with a variety of techniques to form passageways. The dielectric coating may provide a barrier to prevent shorting between the dielectrically coated electrode and a conductive fastener embedded within tissue. Alternately, a cartridge coating can be used to reduce an electric surface sheet charge on the cartridge thermoplastic that can occur during the application of RF energy to tissue.

摘要： A suturing apparatus for the continuous application of a suture includes a suturing head shaped and dimensioned for attachment to a distal end of a support member. The suturing head includes a track shaped and dimensioned for receiving a needle for movement about the track. A support arm includes first and second lateral arms connected by a central connecting member supporting the track, wherein the support arm includes a longitudinal axis and the track lies in a transverse plane. Angular orientation of the support arm relative to the track is achieved by positioning the transverse plane of the track at an oblique angle relative to the longitudinal axis of the support arm such that operators are provided with improved access to the surgical site. A drive assembly is coupled to the needle for controlled movement about the track.

摘要： A roll-up wound protector has a distal ring, a proximal ring, and a flexible sleeve extending between the proximal and distal rings. The proximal ring is rollable to gather the flexible sleeve around the proximal ring and shorten the length of the flexible sleeve. The cross-sectional geometry of the proximal ring may be generally s-shaped. The cross-sectional geometry may be asymmetric about the longitudinal axis and asymmetric about the lateral axis. The height along the longitudinal axis may be greater than the width along the lateral axis. The proximal ring may comprise a medial surface having a circumferential recess and a lateral surface having a circumferential recess, the two recesses being longitudinally staggered relative one another.

摘要： An ultrasonic surgical instrument includes a large thumb slide actuator and a handle which is held in to the palm of a surgeon operator to balance the weight of the instrument during usage. The surgeon's thumb is placed upon the thumb slide actuator, thereby facilitating actuation with a pulling-pushing motion of the thumb slide. When the thumb slide is pushed forward in a distal direction, a rotational clamp arm is opened relative to a stationary blade, and when the thumb slide is pulled rearward in a proximal direction, the clamp arm is closed. This arrangement eliminates a problem with steadying the instrument, with the entire thumb resting on the thumb slide, and also eliminates pressure points on the thumb during long transection times. The large thumb slide features a ribbed texture on its upper surface to prevent thumb slippage. The thumb slide is optimized for ergonomic usage with all size hands, with the user being able to initiate an open or close movement from any point on the thumb slide. The thumb slide has a horizontal S shaped design which fits the normal curvature of the thumb to provide greater comfort and control. The thumb slide is actuated proximally and distally along the same arc which the thumb follows naturally when bent proximally and distally at the first knuckle, which provides the surgeon with a natural and familiar actuating movement for greater ease and control.
摘要翻译：超声波手术器械包括大拇指滑块致动器和手柄，该手柄保持在外科医生操作者的手掌中以在使用期间平衡器械的重量。外科医生的拇指被放置在拇指滑块致动器上，从而便于拇指滑块的推拉运动而致动。当拇指滑块沿远端方向向前推时，旋转夹臂相对于固定刀片打开，并且当拇指滑块沿近侧方向向后拉动时，夹紧臂关闭。这种布置消除了使仪器稳定的问题，整个拇指靠在拇指滑块上，并且在长时间的横切时间内消除了拇指上的压力点。大拇指滑块在其上表面具有肋状纹理，以防止拇指滑动。拇指滑块针对符合人体工程学的使用进行了优化，使用了所有尺寸的手，用户可以从拇指滑块上的任意点启动打开或关闭的移动。拇指滑块具有适合拇指的正常曲率的水平S形设计，以提供更大的舒适性和控制。拇指滑块沿着同一弧线向近侧和远端致动，当拇指在第一关节处向近端和远端弯曲时，拇指自然接触，这为外科医生提供了更自由和熟悉的致动运动，从而更容易和控制。
