    摘要: A method for monitoring a data structure maintained by guest software within a virtual machine is disclosed. Changes to the contents of the data structure are determined, such as by placing write traces on the memory pages containing the data structure. Also, the method involves determining when memory pages containing the data structure are swapped into and/or out of guest physical memory by the guest software, such as by placing write traces on the memory pages containing the guest page table and detecting changes to the present bit of page table entries involved in mapping virtual addresses for the data structure. Information about the contents of the data structure is retained while memory pages containing the data structure are swapped out of guest physical memory.

    摘要: http://www.wipo/int/pctdb/images/PCT-IMAGES/31122008/CN2008001226_31122008_gz_en.×4-b.jpgA surgical stapling head assembly with a rotary cutter comprises a casing (101), an annular cutter (103), a staple driver (102) and a staple holder. Said staple driver (102) is connected with the annular cutter (103) by a bearing structure (109) with guiding projections (115a, 115b, 115c) disposed thereon, on the outer wall of the anti-expansion tube (104) or the inner wall of the casing (101) is molded with a metal cylinder member (105), on which is provided with a forward helix track (106) and a backward track (107) independent and communicated with each other, the guiding projections (115a, 115b, 115c) engaging with the two guiding tracks (106, 107) to guide the annular cutter (103) to forward in way of helix.
