  • Patent number: 12121236
    Abstract: An electric surgical stapler with state display is provided, which includes a housing, an anastomosis bobbin, a jaw, a dynamic structure, a power supply structure, a control board, a state display screen, and an RF antenna. The dynamic structure, power supply structure, state display screen, and RF antenna are respectively electrically connected with the control board; the housing includes a display slot, an antenna slot, and a board slot. The state display screen is provided in the display slot, the RF antenna is provided in the antenna slot, the control board is provided in the board slot. The state display screen and RF antenna are arranged in parallel. In working state, the dynamic structure is controlled to drive the jaw to perform by the control board, thereby completing closing, firing, retraction and other operations, the state display screen synchronously displays an operation state and progress of the jaw.

  • Patent number: 9924945
    Abstract: An improved surgical apparatus actuator includes a nail bin assembly (1002), a nail anvil assembly (1001) connecting with the nail bin assembly (1002), and a drive assembly (1003) controlling the nail bin assembly (1002) and the nail anvil assembly (1001) to convert between opening and closing conditions. The nail anvil assembly (1001) includes a nail anvil plate (103) and a nail anvil seat (102), wherein the nail anvil plate (103) is provided on an inner side (1022) of the nail anvil seat (102), the nail anvil seat (102) has the structure, material and processing technology capable of providing high anti-bending performance, the nail anvil plate (103) is cold-punched from a thinner stainless steel sheet. Therefore, the processing difficulty of the components is reduced, and meanwhile, the ability of the actuator chuck to resist bending deformation is improved.
