Surgical Stapler Patents (Class 227/175.1)
  • 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.

  • Patent number: 11202627
    Abstract: A staple housing includes an array of staples each in a staple delivery position or “ready position” ready to be fired into target tissue. A staple driver is advanceable to drive the ready-position staples from the staple head into the tissue using staple pushers. During use, the staples in the ready positions are simultaneously fired into the target tissue using the staple pushers, forming an array of staples in the target tissue. After the array has been fired, one or more feed mechanisms within the staple housing advance a second group of staples from one or more staple storage locations into the ready positions in preparation for firing of the second group of staples.

  • Patent number: 11179153
    Abstract: A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied without the need to use different sizes of staples.

  • Patent number: 11166724
    Abstract: A buttress assembly for use with a surgical stapled site has a buttress and an adhesive on one side of the buttress. The adhesive on the buttress is applied in a pattern where the adhesive extends near or along the edges of the buttress while a center region of the buttress remains relatively free of adhesive. The adhesive is applied such that it extends continuously along the buttress and has a height such that the adhesive creates a sealing attachment with an end effector. The adhesive can be applied in an uneven distribution such that there is more adhesive applied at one end of the buttress than the other. The adhesive can also be applied in a symmetric or asymmetric distribution about a longitudinal axis of the buttress.
