An apparatus includes a handle assembly having a body, a shaft assembly having an outer tube member, an end effector, an anvil, a first trocar closure system, and a second trocar closure system. The end effector has having a staple deck fixed relative to the body, a staple driver operable to actuate relative to the staple deck between an unfired position and a fired position, and the trocar configured to selectively couple with the anvil and actuate relative to the staple dreck. The first trocar closure assembly can actuate in a first motion to drive the trocar between a distal position and a first closed position. The second trocar closure assembly can actuate in a second motion between the first closed position and a second closed position. The staple drive is inoperable at least until the first trocar closure assembly actuates the trocar to the first closed position.

A method of suturing a trocar path incision in a tissue of a patient with an obturator includes inserting the obturator through the tissue such that a shaft of the obturator extends through a tissue opening about the trocar path incision and a distal tip of the obturator is positioned within a cavity of the patient. The method also includes directing the suture via a suturing feature with the obturator inserted through the tissue in order to direct the suture relative to the tissue. Furthermore, the method includes closing the tissue opening about the trocar path incision with the suture.

Method of suturing a trocar path incision

An apparatus includes a body assembly with a handle and a shaft portion, an end effector with a staple deck fixed to the shaft portion, an anvil, and a firing assembly. The end effector further includes a trocar and a staple driver both configured to actuate relative to the staple deck. The staple driver can actuate a distance between an unfired position and a fired position. The trocar can couple with the anvil to define a gap distance. The firing assembly includes a trigger pivotably coupled with the body assembly via a first pivot, a driver actuator configured to actuate the staple driver, and a linkage assembly pivotably coupled with the trigger via a second pivot and the driver actuator. Where the second pivot is proximal relative to the first pivot. The linkage assembly can drive the driver actuator is response to the trigger pivoting about the first pivot.

Dual lever to reduce force to fire in circular surgical stapler

An apparatus includes a handle assembly having a body, a shaft assembly having an outer tubular member extending distally from the body, an end effector, an anvil, and a trocar latch assembly. The end effector includes a staple deck fixed relative to the outer tubular member, a staple driver that can actuate relative to the staple deck between an unfired position and a fired position, and a trocar that can actuate relative to the staple deck and the staple driver, the anvil can couple with trocar to move relative to the staple deck to define a gap distance. The trocar latch assembly includes a locking body that can actuate between an unlocked configuration and a locked configuration in response to the staple driver actuating between the unfired position and the fired position. The locking body can selective fix the trocar relative to the staple deck in the locked position.

A trocar assembly includes a cannula assembly, an obturator assembly, and a catch arm. The cannula assembly has a housing, a cannula, and a working channel defining a longitudinal axis from a proximal opening to a distal opening. The obturator assembly includes a proximal head, a distal tip, and a shaft extending therebetween. The catch arm is selectively moveable from a retracted position to a first and second deployed positions and is configured to releasably capture a suture thread. In the retracted position, the catch arm is positioned radially inward from the first deployed position. In the first deployed position, the catch arm is positioned radially outward from the retracted position. In addition, the catch arm is configured to be moved a predetermined distance from the first deployed position to the second deployed position and release the captured suture thread therefrom.
