Compressive force sensor for handheld electromechanical surgical system

The present disclosure provides a surgical device including a tool assembly and a drive assembly. The tool assembly includes: a distal portion including a plurality of staples; and an anvil assembly movable relative to the distal portion from an open position to a clamped position. The handle assembly includes: an access mechanism coupled to the anvil assembly and configured to move the anvil assembly from the open position to the clamped position; a force sensor disposed at a distal end of the surgical device; and a controller. The force sensor is configured to sense a change in resistance indicative of a force exerted on the compressed tissue and the proximity mechanism. The controller is configured to receive a signal indicative of the force measured by the force sensor and provide an indication of the sensed force. 本公开提供了一种外科装置，该外科装置包括工具组件和驱动组件。该工具组件包括：远侧部分，该远侧部分包括多个钉；和砧座组件，该砧座组件能够相对于该远侧部分从打开位置移动到夹紧位置。该手柄组件包括：接近机构，该接近机构耦接到该砧座组件并且被配置为将该砧座组件从该打开位置移动到该夹紧位置；力传感器，该力传感器设置在该外科装置的远侧端部处；和控制器。该力传感器被配置为感测指示施加在被压缩组织上
