  • Patent number: 11324504
    Abstract: A surgical stapler includes a body, a shaft assembly, and an end effector configured to receive a staple cartridge. The end effector is actuatable between an open state for receiving tissue and a closed state for clamping the tissue. A closure system operatively coupled with the end effector is operable to actuate the end effector from the open state to the closed state. A firing system operatively coupled with the end effector is actuatable to fire the end effector to staple and cut the clamped tissue. A lockout member operatively coupled with the closure system and the firing system is configured to inhibit actuation of the closure system to prevent closure of the end effector when an unspent staple cartridge is absent from the end effector. The lockout member is also configured to inhibit actuation of the firing system to prevent repeated firing with the same staple cartridge.

  • Patent number: 11317910
    Abstract: Aspects of the present disclosure are presented for a surgical instrument having one or more sensors at or a near an end effector and configured to aide in the detection of tissues and other materials and structures at a surgical site. The detections may then be used to aide in the placement of the end effector and to confirm which objects to operate on, or alternatively, to avoid. Examples of sensors include laser sensors used to employ Doppler shift principles to detect movement of objects at the surgical site, such as blood cells; resistance sensors to detect the presence of metal; monochromatic light sources that allow for different levels of absorption from different types of substances present at the surgical site, and near infrared spectrometers with small form factors.
