    摘要： A laparoscopic bipolar electrosurgical instrument can apply a large closure force between its jaws without damaging the small yoke assembly. The instrument comprises: a first jaw having a first flange with a first slot, and a second jaw having a second flange with a second slot, wherein the first and second jaws are located at a distal end of the instrument and comprise an electrically conductive material for conducting bipolar electrosurgical current therebetween; a yoke attached to a pushrod and positioned to electrically insulate the first flange from the second flange, the yoke having a first side facing the first flange and a second side facing the second flange, the yoke further comprising a first shoulder and a second shoulder, a first pin located on the first side and movably engaged with the first slot; a second pin located on the second side and movably engaged with the second slot; the first slot and the second slot shaped such that an angle, subtended by the first and second jaws, decreases with distal motion of the pushrod, and first and second cul-de-sacs positioned respectively in the first and second slots to relieve shear stresses on the first and second pins approximately when the first and second shoulders respectively engage the first and second flanges to provide a closure force between the first and second jaws.

    摘要： A sports racquet including a frame, a string bed, and at least one cantilevered member. The frame includes a head portion coupled to a handle portion. The head portion includes a distal region, first and second side regions, and a proximal region. A string bed is formed of a plurality of cross string segments and a plurality of main string segments. The cantilevered member has a first section coupled to one of the regions, such that at least one point on the first section remains substantially fixed in relation to the region to which the first section is coupled, and a second section that is deflectable relative to the region to which the first section is coupled. At least one of the string segments is operably engaged with the member, such that when a ball impacts the string segment, the second section deflects inward toward the string bed.
