    • A cycling, suturing and knot-tying device is characterized by an arcuate fixed, grooved or recessed way provided in a correspondingly shaped support frame for accommodating a curved needle fitted with thread, and frictional needle-engaging devices provided in the way for selectively engaging the needle and driving the needle in one or both rotational directions to suture a wound with the thread. Selective articulation of the frame and the way and driving of the needle in the way by positioning the frictional needle-engaging devices with respect to the needle are typically effected by manipulation of a pistol-grip operating apparatus having a transmission tube that mounts the frame and the way in articulating relationship and rotates and articulates with respect to the pistol grip and carries various operating elements that interface with the frictional needle-engaging devices in the way. In at least one embodiment needle direction-adjusting elements are provided in the frame in cooperation with selected devices in the way for determining the direction of needle rotation responsive to manipulation of an interfacing operating element located on the operating apparatus. Auxiliary thread-handling or incrementing and knot-tying devices are also disclosed.

    • The bipolar modular forceps assembly is a disposable electrosurgical device utilized with an RF voltage supply to weld soft tissue to prevent bleeding when cut or excised. The device consists of two modularly constructed arms arranged in scissor configuration that clamp when the arms are apart and open when the arms are squeezed together. The wires enter from the rear of the device, behind the digit insertion of the upper arm, and run through the interior of the upper arm before reaching the pivot point. From the pivot joint, one wire continues to the bottom jaw and the other wire wraps around the pin bushing in the pivot joint and proceeds to the top jaw. At all times the wires are fully insulated by the insulative cover with the only exposed wire occurring where they enter the device. The bipolar voltage of each wire is transferred to an electrode on each jaw. The electrodes are insulated from surrounding tissue by the insulative jaw, which contains visible markings showing the beginning, middle and end of the electrode. Both the insulative jaw and the electrode are interchangeable and made from moldable material to allow for different sizes and shapes. When no voltage is applied the tool can be used as a blunt dissector.
    • 双极模块镊子组件是与RF电压源一起使用的一次性电外科装置,用于焊接软组织以防止在切割或切除时出血。 该装置由两个以剪刀构造布置的模块构造的臂组成,当臂被挤压在一起时,当臂分开并打开时夹紧。 电线从设备的后部进入,在上臂的数字插入后面,并且在到达枢轴点之前穿过上臂的内部。 从枢轴接头,一条线继续到底部钳口,而另一条线绕枢轴接头中的销轴套缠绕,并进入顶部钳口。 在任何时候,导线被绝缘盖完全绝缘,其中仅有暴露的导线进入设备。 每根电线的双极性电压转移到每个钳口上的电极上。 电极通过绝缘钳口与周围组织绝缘,其中包含显示电极的开始,中间和末端的可见标记。 绝缘钳和电极均可互换,并由可模制材料制成,以允许不同的尺寸和形状。 当没有施加电压时,该工具可以用作钝分离器。
