    • A bipolar electrosurgical instrument has opposable seal surfaces on its jaws for grasping and sealing vessels and vascular tissue. Inner and outer instrument members allow arcuate motion of the seal surfaces. An open lockbox provides a pivot with lateral support to maintain alignment of the lateral surfaces. Ratchets on the instrument members hold a constant closure force on the tissue during the seal process. A shank portion on each member is tuned to provide an appropriate spring force to hold the seal surfaces together. During surgery, the instrument can be used to grasp and clamp vascular tissue and apply bipolar electrosurgical current through the clamped tissue. In one embodiment, the seal surfaces are partially insulated to prevent a short circuit when the instrument jaws are closed together. In another embodiment, the seal surfaces are removably mounted on the jaws.
    • 双极电外科器械在其钳口上具有对置的密封表面,用于抓住和密封容器和血管组织。 内部和外部仪器构件允许密封表面的弓形运动。 开放的锁箱提供具有侧向支撑的枢轴以保持侧面的对准。 仪器构件上的棘轮在密封过程中在组织上保持恒定的闭合力。 调整每个构件上的柄部分以提供适当的弹簧力以将密封表面保持在一起。 在手术过程中,仪器可用于掌握和夹紧血管组织,并通过钳夹的组织施加双极电外科电流。 在一个实施例中,密封表面是部分绝缘的,以防止当仪器钳口闭合在一起时发生短路。 在另一个实施例中,密封表面可移除地安装在夹爪上。

    • A laparoscopic bipolar electrosurgical instrument (10) for sealing tissue includes a handle (14) having an elongated tube (13) affixed thereto. The tube includes first (15) and second (16) jaw members having electrically conductive sealing surfaces (39, 40) attached to a distal end (12) thereof which are movable from a first position for approximating tissue to a second position for grasping tissue therebetween. The handle (14) includes a fixed handle (50) and a handle (52) which is movable relative to the fixed handle to effect movement of the jaw members (15, 16) from the first position to the second position for grasping tissue. The jaw members connect to a source of electrosurgical energy such that the opposable sealing surfaces are capable of conducting electrosurgical energy through tissue held therebetween. A stop (33, 90, 95) is included for maintaining a minimum separation distance between opposing sealing surfaces (39, 40). A ratchet (60, 62) is also included to maintain a closure force in the range of about 7 kg/cm2 to about 13 kg/cm2 between opposing sealing surfaces.

    • A surgical safety apparatus for use in connection with an energizable surgical device prevents inadvertent activation of a surgical tool. The energizable surgical device may include an electrosurgical system, a laser scalpel, an ultrasonic aspirator, and combinations thereof. An activation circuit is in connection with the source of energy and in connection with the handpiece. The activation circuit has two states: the first state disconnects the source of energy from the handpiece, the second state connects the source of energy to the handpiece. A sensing element is connected to the activation circuit. The sensing element signals the activation circuit to convert the activation circuit from the first state to the second state. The activation circuit may remain in the second state for a preestablished period of time followed by a reversion to the first state. The activation circuit may include a relay which may be connected to operate accessories including smoke evacuators, lights, videos or irrigators. The sensing element may be disposed to sense the proximity of the surgical tool to the surgical site. The sensing element may be disposed to sense a voice command. The sensing element can monitor the activations of an electrical switch associated with the surgical tool. If the sensing element detected a specified timed pattern of activations of the electrical switch, for example a double click, then the sensing element would signal the activation circuit to convert to the second state.
