Method for recording probe movement and determining an extent of matter removed

A method and system for determining an extent of matter removed from a targeted anatomical structure are disclosed. The method includes acquiring an initial representation of a targeted anatomical structure and then removing matter from the targeted anatomical structure. An instrument is then navigated within the targeted anatomical structure. The instrument includes a tracking array, and a relative position of the instrument within the targeted anatomical structure is determined by the tracking array. The method includes recording the relative position of the instrument within the targeted anatomical structure to determine a final representation of the targeted anatomical structure. Finally, the method includes determining an extent of matter removed from the targeted anatomical structure by comparing the initial representation of the targeted anatomical structure with the final representation of the targeted anatomical structure. Indicators are provided to convey the extent of matter remaining within the targeted anatomical structure.

Temporary fixation tools for use with circular anastomotic staplers

The present invention relates to circular anastomosis stapler and kits comprising reinforcing buttress materials and fixation tools that are slidably installed on the anvil shaft of such staplers which provides a temporary mechanical fixation of a reinforcing buttress to the anvil surface of a circular stapler during the insertion of the anvil into the tubular tissue. When the anvil, loaded with the buttress, is in the desired location, the fixation tool is pulled back along the anvil shaft and removed. The shaft is then connected to the stapling head and the stapling is performed. The present invention also relates to methods for using the kits and devices therein.
