Abstract

According to an aspect of the present disclosure, an endoscopic surgical device is provided. The surgical device includes a handle assembly including a drive mechanism actuatable by a trigger; and an endoscopic assembly including a proximal end portion extending from the handle assembly; a distal end portion pivotably connected to the proximal end portion of the endoscopic assembly; and a rotatable inner actuation shaft extending from the handle assembly and into the distal end portion of the endoscopic assembly, the inner actuation shaft including a flexible portion extending across the pivot connection. The surgical device includes an end effector selectively connectable to the distal end portion of the endoscopic assembly and to a distal portion of the rotatable inner actuation shaft. The surgical device includes a shipping wedge to support an end effector.

First claim

What is claimed is:

1. A shipping wedge for an end effector of an endoscopic surgical device, comprising:
an elongate body for receiving an elongate body portion of an endoscopic surgical device, the elongate body including a first pair of opposed sidewalls that define a first U-shaped channel, the first U-shaped channel extending longitudinally through the elongate body, the first U-shaped channel defining a first longitudinal axis;
a central vertical axis of the first U-shaped channel defining a first plane that is parallel to the sidewalls of the elongate body;
an angled body that extends from the elongate body at an acute angle relative to the elongate body, the angled body including a second pair of opposed sidewalls that define a second U-shaped channel, the second U-shaped channel defining a second longitudinal axis and supporting an end effector for connection to the elongate body portion of the endoscopic surgical device;
a central vertical axis of the second U-shaped channel defining a second plane that is parallel to the sidewalls of the angled body, wherein the first plane of the first U-shaped channel and the second plane of the second U-shaped channel are co-planar; and
an alignment rib extending from the first pair of opposed sidewalls of the elongate body, the alignment rib positioned at the intersection of the first longitudinal axis and the second longitudinal axis;
wherein the first U-shaped channel and the second U-shaped channel are in communication with one another and permit movement of the end effector from a first position aligned with the second longitudinal axis to a second position aligned with the first longitudinal axis.

2. The shipping wedge of claim 1 , wherein the alignment rib defines a passage that extends through the alignment rib.

3. The shipping wedge of claim 1 , wherein the angled body includes a protuberance that extends from an inner surface of the angled body.

4. The shipping wedge of claim 1 , further comprising alignment flanges that extend from at least one of the first and second pairs of opposed sidewalls.

5. The shipping wedge of claim 1 , wherein the angled body prevents the end effector from moving when the end effector is supported within the second U-shaped channel and positioned in axial alignment with the second longitudinal axis.

6. The shipping wedge of claim 5 , wherein the first U-shaped channel enables the end effector to move through the first U-shaped channel when the end effector is positioned in axial alignment with the first longitudinal axis.

7. The shipping wedge of claim 2 , wherein the passage that extends through the alignment rib divides the alignment rib creating a pair of alignment ribs.

8. The shipping wedge of claim 7 , wherein the alignment ribs secure the end effector within the angled body.

9. The shipping wedge of claim 1 , wherein the elongate body includes a length, the first U-shaped channel extending along an entirety of the length of the elongate body.

10. The shipping wedge of claim 1 , wherein the second U-shaped channel extends beyond a terminal end of the first U-shaped channel.
