A surgical stapler includes a head in which a plurality of staples are stored. The head includes a facing surface. The stapler also includes an anvil having an anvil surface shaped and dimensioned for forming the staples upon actuation of the surgical stapler, the anvil including a facing surface opposed to the facing surface of the head for mating engagement therewith. The facing surface of the head is obliquely oriented relative to a longitudinal axis of the head creating an elliptical staple line when the head is brought into contact with anvil during actuation of the surgical stapler.

The present disclosure relates to surgical instruments including a staple anvil formed in a distal end of the surgical stapler and a staple cartridge selectively receivable in a distal end of the surgical stapler and in juxtaposition relative to the staple anvil, the staple cartridge including one or more laterally spaced apart rows of staple slots formed in an upper surface thereof, a plurality of surgical staples disposed, one each, within the staple slots, and a staple line reinforcing system configured and adapted to augment the strength of the staple line formed by the firing of the surgical staples into body tissue, wherein the surgical stapler concomitantly drives the plurality of surgical staples through the adjacent layers of body tissue to mechanically secure the body tissue and activates the reinforcing system to non-mechanically secure the adjacent layers of body tissue to one another.

A staple line buttress material having an adhesive surface, packaged and provided in sterile, ready-to-use form. The material can be used to retrofit surgical staplers to provide an improved staple line, and with improved ease of use.

The invention relates to a stapler with a stapling ruler. The stapler is characterized in that a push-pull type, a screw type or a drawer type stapling ruler consisting of a left ruler part and a right ruler part is designed on the base of the existing stapler. When the stapler is not used, the left ruler part and the right ruler part are folded and stored in the base; when the stapler is used, the left ruler part and the right ruler part respectively rotate at 90 degrees towards the left side and the right side of the base to form the stapling ruler; the length of the stapling ruler is greater than the width of the base; scale lines on the ruler are used for determining distance and parallel relation between a stapling line with paper edge; a distance value between the upper paper edge and the center point of a staple and a distance value between the lower paper edge and the center point of the stapler, so that the stapling is more accurate and convenient; a baffle on the stapling ruler can baffle the paper and has the effects of neatening and fixing paper; the high movability during stapling the paper can be solved, so that the stapling is more quick and accurate. Through the stapler with the stapling ruler, the easily-occurred problems that more than staples are not located on the same stapling line, the stapled edges are unparallel and are unequal in distance, and the distance between the upper edge and the lower edge of the paper cannot conform to the stapling requirement when during stapling via the existing stapler can be effectively solved.

A disposable staple cartridge for a surgical cutting and fastening instrument. Various embodiments include a disposable anvil that is supported relative to the cartridge body and movable between open and closed positions. At least one tissue stop is provided on the disposable anvil for orienting the tissue to be cut and stapled relative to the staples supported within the cartridge body. Other embodiments relate to end effectors for surgical cutting and fastening instruments that can be used in connection with a plurality of staple cartridge bodies that each have a common length but which maydifferent lengths of staple lines.

A method for assessing suture line integrity includes loading a navigation plan into a navigation system, the navigation plan including a planned pathway shown in a 3D model, inserting a probe into a patient's airways, the probe including a location sensor in operative communication with the navigation system, registering a sensed location of the probe with the planned pathway, and selecting a target in the navigation plan, the target including a proposed suture line. The method further includes presenting a view of the 3D model showing the planned pathway and indicating the sensed location of the probe, navigating the probe through the airways of the patient's lungs toward the target, and imaging the proposed suture line of the target, via the probe, to determine tissue integrity surrounding the proposed suture line.

The present invention provides adjunct materials for delivery to colon tissue. Generally, the appendage material can be configured to be delivered to colonic tissue by staple deployment from a cartridge body of a surgical stapler to form at least one deployed staple thread. The appendage material may be formed from a fibrous matrix and include an effective amount of one or more agents for delivery to the colonic tissue. The agent is disposed within and releasable from the appendage material and is effective to promote a desired effect on the blood vessel, such as angiogenesis and / or vasodilation, along the at least one deployed staple line. Also provided are methods of applying such adjunct materials to colonic tissue using a cartridge assembly or an end effector.

A surgical instrument (20) adapted for applying a plurality of surgical fasteners to body tissue, the surgical instrument comprising: a frame having a proximal end and a distal end, with a handle (21) positioned at the proximal end and an end effector (80) positioned at the distal end; the end effector being shaped and dimensioned for supporting a cartridge housing (121) and an anvil (122), the cartridge housing and anvil structure being relatively movable between a first spaced apart position and a second position in close approximation with one another; a firing mechanism associated with the end effector and the cartridge housing for selective actuation of the fastening elements for treatment of an individual; and a tissue retention feature (124,125) associated with the cartridge housing and anvil, the tissue retention feature maintaining tissue within the end effector during treatment; wherein the cartridge housing includes staple lines defining the longitudinal extent of the staples being applied via the cartridge module, and the longitudinal extent of the staple line is greater than the longitudinal extent of the tissue retention feature. <IMAGE>
