  • Publication number: 20150238088
    Abstract: A jaw assembly including first and second jaw members configured to clamp tissue therebetween. The first jaw member includes a surface opposing a surface of the second jaw member, a light source, and a light detector. The light source is configured to emit light from an opening defined in the surface of the first jaw member. The light detector is disposed within the opening and is configured to sense properties of light reflected off tissue clamped between the first and second jaw members and to generate signals indicative of the sensed properties of light. A processor is operatively associated with the light detector and is configured to receive the signals from the light detector. The processor is also configured to analyze the signals to determine an attribute of tissue clamped between the first and second jaw members and to provide feedback to a user of the attribute of the tissue.

  • Publication number: 20150080862
    Abstract: A surgical instrument includes an outer housing shell defining a cavity. The outer housing shell defines an upper outer housing half and a lower outer housing half. The upper outer housing half defines a longitudinal axis. An instrument module is selectively insertable into the cavity of the outer housing shell. The instrument module includes an inner housing shell, at least one motor disposed within the inner housing shell, a control board being in electrical communication with the at least one motor, and an energy source being in electrical communication with the at least one motor and the control board. The instrument module is inserted into the cavity of the outer housing shell in such a manner that the operative axis of the at least one motor is substantially parallel to the longitudinal axis of the upper outer housing half.

  • Patent number: 8968340
    Abstract: An end effector for use in an endoscopic stitching device includes a fixed jaw, a moveable jaw, a linkage member, needle engaging blades and a rotatable member. The moveable jaw is pivotably associated with the fixed jaw about a first pivot axis. The linkage member is pivotably associated with the moveable jaw about a second pivot axis. The needle engaging blade is slidably supported in each of the fixed and moveable jaws. An axial movement of the linkage member causes the moveable jaw to pivot about the first pivot axis with respect to the fixed jaw, and rotation of the rotatable member causes opposed axial movement of the pair of needle engaging blades.
