Surgical Stapler Patents (Class 227/175.1)
  • Patent number: 10772679
    Abstract: A surgical system for connecting body tissue is provided. The surgical system includes a surgical instrument having two tool elements movable relative to each other, each of which comprises a high-frequency electrode. The high-frequency electrodes, in an approach position of the tool elements, define a minimum distance from each other, lying opposite each other and facing each other. The instrument has a shaft at the distal end of which at least a first one of the tool elements is arranged or formed. A second tool element is movable from an operating position, in which it is adapted for movement into the approach position, into a removal position and/or vice versa. A surface area of a perpendicular projection of the second tool element onto a projection plane extending perpendicularly to a shaft direction in a region of the second tool element is smaller in the removal position than in the operating position.

    Abstract: Devices, systems and/or methods for repairing a lacerated tendon or ligament adjacent a repair site. In one embodiment, a repair device includes an elongated flexible structure and multiple anchors, the multiple anchors pre-positioned with the elongated flexible structure. The repair device may be coupled to the tendon or ligament at the repair site with a delivery device. The repair device may be pre-positioned in a cartridge such that the cartridge is loaded into the delivery device. The lacerated tendon or ligament is positioned within a cradle portion of the delivery device such that the tendon is positioned between the cradle portion and the cartridge that holds the repair device. The delivery device may then be triggered to actuate and drive the repair device from the cartridge to couple to the lacerated tendon or ligament. In this manner, the repair device may be anchored to the lacerated tendon.
