The present disclosure includes apparatuses for a surgical reloadable cartridge assembly. An example apparatus includes a blade assembly which comprises leaves and an I-beam. In an example there are two outer leaves and at least one inner leaf. The two outer leaves are connected to the I-beam. The at least one inner leaf is not connected to the outer leaves and is connected to the I-beam with a connection that allows the at least one inner leaf to move relative to the I-beam while not being pulled away from the I-beam when tension is applied to the at least one inner leaf.

The present disclosure includes apparatuses for a surgical handle assembly. An example apparatus includes a movable handle member and a switch configured to provide two or more modes of operation for the movable handle member and a driving pawl pivotally connected to a swing wheel configured to advance an actuation shaft linearly in a distal direction in response to actuation of the movable handle member.

Surgical handle assembly

The present disclosure is directed to a multidirectional apparatus that can be attached to a stapler reload apparatus. The multidirectional apparatus can include at least two articulation elements each comprising a cylindrical proximal end, a hemispherical distal end, a central lumen, a wall surrounding the central lumen, and a first pull wire lumen within the wall surrounding the central lumen, wherein the hemispherical distal end of a first articulation element of the at least two articulation elements is nested in the cylindrical proximal end of a second articulation element of the at least two articulation elements and a first pull wire positioned within the first pull wire lumen, and wherein tension applied to the first pull wire causes the second articulation element to move away from a longitudinal axis of the at least two articulation elements in a direction of the first pull wire which is experiencing the tension.

Multidirectional apparatus

The present disclosure includes apparatuses for a motorized surgical handle assembly. An example apparatus includes a non-movable handle, a movable handle configured to be moved away from and into proximity with the non-movable handle, wherein the movable handle comprises a locking protrusion, a selector lever configured to rotate between a locked position and an unlocked position, and a selector cam coupled to the selector lever, wherein the selector cam comprises a surface with a concave locking opening, and wherein the selector cam is configured to rotate in response to the selector lever rotating, wherein, when the movable handle is in proximity with the non-movable handle and the selector lever is in the unlocked position, the surface with the concave locking opening is positioned adjacent to the locking protrusion to lock the movable handle in place.

Motorized surgical handle assembly

The present disclosure includes apparatuses for a surgical reloadable cartridge assembly. An example apparatus includes a lock slider and a blade lock configured to actuate radially between a first position that locks a blade in a secure position and a second position that allows the blade to move longitudinally.

Safety control algorithms for surgical devices, including safety control algorithms for surgical stapler devices, and associated systems, devices, and methods. In one embodiment, a method of operating a surgical stapler comprises tracking a position of a distal end of a blade assembly of a reloadable cartridge assembly of the surgical stapler as the distal end of the blade assembly is moved, via actuation of a motor and a corresponding drivetrain, along a stroke of the blade assembly. The method can further comprise adjusting a current limit for current levels in the drivetrain based on the position of the distal end of the blade assembly along the stroke.

The present disclosure includes apparatuses for a reloadable cartridge assembly. An example apparatus includes a first elongated member including a staple cartridge configured to eject a number of staples and a second elongated member pivotally coupled to the first elongated member, wherein the second elongated member includes a number of pockets configured to receive and form the number of staples ejected from the staple cartridge, and wherein a furthest distal pocket of the number of pockets is less than 6 millimeters (mm) from a distal end of the second elongated member.

Reloadable cartridge assembly

The present disclosure includes apparatuses for a surgical handle assembly. An example apparatus includes a reloadable cartridge assembly and a surgical handle assembly including an articulation assembly configured to maintain the reloadable cartridge assembly in a first operation position, the articulation assembly comprising a knob in a first knob position coupled to a housing and a spring coupled to the housing configured to bias a sphere radially outward to a first slot of a radial position component.

Surgical handle articulation assembly

The present disclosure includes apparatuses for a surgical stapler. An example surgical stapler can include a handle assembly and a body portion extending from the handle portion, the body portion having a staple cartridge assembly, the staple cartridge assembly defining a first row of staple receiving slots, the staple receiving slots have an outer edge, wherein the staple receiving slots are arranged in a generally radial orientation with respect to the center axis of the staple cartridge assembly.

Surgical stapler

The present disclosure includes apparatuses for a surgical handle assembly. An example apparatus includes a toothed rack, a tab configured to provide a reverse mode of operation for the toothed rack by engaging a reverse gear, and a trigger gear connected to the reverse gear and to a movable handle member configured to reverse the toothed rack linearly in a proximal direction in response to actuation of the movable handle member.
