Abstract: Apparatus and methods for improved tissue cutting of circular stapling instruments include a cartridge assembly configured to maximize the force during a cutting stroke. In embodiments, the cartridge assembly is configured to maintain engagement between a knife assembly and a drive member during retraction of the knife. Alternatively, or in addition, the cartridge assembly is configured to prevent incidental advancement of the knife assembly.

Abstract: A method for obviating spline crash in a surgical stapler that utilizes a motor of the surgical stapler includes oscillating an anvil retainer of the surgical stapler in a first oscillation pattern, oscillating the anvil retainer in a second oscillation pattern that is different from the first oscillation pattern after the first oscillation pattern, and retracting the anvil retainer until an anvil of the surgical stapler is in a clamped position relative to a shell assembly after the second oscillation pattern. Oscillating the anvil retainer in the first oscillation pattern includes oscillating the anvil retainer in a longitudinal direction between extension and retraction with the motor such that the anvil moves towards and away from the shell assembly. Oscillating the anvil retainer in the second oscillation pattern includes moving the anvil towards and away from the shell assembly.

Abstract: A circular stapling instrument includes an adapter assembly having a tubular body, a shell assembly disposed on a distal portion of the tubular body, and a seal assembly supported on the tubular body. The seal assembly includes an inflatable member disposed proximal of the shell assembly, wherein the inflatable member includes a first diameter when in a deflated condition and a second diameter when in an inflated condition, the second diameter being larger than the first diameter.

Abstract: A surgical device includes an elongate body, a tool assembly, a drive assembly, and an articulation mechanism for moving the tool assembly between a non-articulated position and articulated positions. The articulation mechanism includes an articulation link, a first pivot link that is positioned on a first side of a flexible beam, and a second pivot link positioned on a second side of the flexible beam. The first and second pivot links are configured to control the path of movement of the flexible beam of the drive assembly as the flexible beam is moved between its retracted and advanced positions in non-articulated and articulated positions of the tool assembly to maintain a predetermined distance of movement of the clamp member within the tool assembly constant.

Abstract: A method for powered surgical stapling instrument rotation adjustment includes measuring a change in position of a first motor shaft of the surgical stapling instrument relative to a stored rotation verification position of the first motor shaft resulting from manual rotation of an adapter assembly of the surgical stapling instrument in relation to a handle assembly of the surgical stapling instrument, determining a distance traveled by a first drive assembly of the adapter assembly of the surgical stapling instrument resulting from the change in position of the first motor shaft, comparing the determined distance traveled to a first stored rotation verification position of the first motor shaft, determining if the compared distance falls into a predetermined acceptable range of rotation positions, and adjusting the position of the drive shaft if the compared distance is not within the predetermined range.

Abstract: A circular stapling device includes an elongate body having a flexible outer tube that supports a reload assembly, a flexible inner cable that supports an anvil assembly, and a flexible central tube that is supported about the inner cable and within the outer tube. The stapling device is configured to access body cavities which cannot be easily accessed by a circular stapling device having a rigid shaft.
