Abstract
An improved surgical apparatus actuator includes a nail bin assembly (), a nail anvil assembly () connecting with the nail bin assembly (), and a drive assembly () controlling the nail bin assembly () and the nail anvil assembly () to convert between opening and closing conditions. The nail anvil assembly () includes a nail anvil plate () and a nail anvil seat (), wherein the nail anvil plate () is provided on an inner side () of the nail anvil seat (), the nail anvil seat () has the structure, material and processing technology capable of providing high anti-bending performance, the nail anvil plate () 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.
