摘要： A bail support and a top drive system for an oilfield drill rig. The top drive system includes a drive apparatus, and the bails have bodies with upper head portions and two spaced-apart legs. Each leg includes an upper leg portion and a lower leg portion. The upper leg portions are non-parallel to each other and extend from the head portion at an angle to a centerline of the bail. Each lower leg portion extends down from its corresponding upper leg portion in a reverse bend.

摘要： A staple cartridge including first and second staple cavities therein where the first cavity can define a first axis and the second cavity can define a second axis. In various embodiments, the first axis can be transverse to the second axis. In one embodiment, the first and second cavities can extend in directions which are not parallel to each other. In various embodiments, staples deployed from such first and second staple cavities can produce a staple pattern which can better constrict blood vessels in soft tissue and reduce blood flow therethrough.
