Endoscopic drop off bag
First Claim
1. A surgical instrument, comprising:
- a hybrid shaft having a proximal end and a distal end, wherein the distal end is flexible, and wherein the proximal end is rigid;
a first collapsible arm located at the distal end of the hybrid shaft, wherein the first collapsible arm comprises a first portion;
a second collapsible arm located at the distal end of the hybrid shaft, wherein the second collapsible arm comprises a first portion and a second portion, wherein the second portion extends distally beyond the first portion of the second collapsible arm in a substantially straight distal direction from the hybrid shaft, and wherein the second portion has a curvature different than a curvature of the first portion of the second collapsible arm;
a bag having an open end and a closed end, wherein the bag is configured to be retained upon the first collapsible arm and the second collapsible arm, wherein the first collapsible arm comprises a single wire segment that extends from the hybrid shaft in a distal direction and terminates at a distal end and the second collapsible arm comprises a single wire segment that extends from the hybrid shaft in a distal direction and terminates at a distal end, the first and second collapsible arms define an opening therebetween such that the bag can be removed from first and second collapsible arms, wherein the bag is removed from first and second collapsible arms by sliding the bag over the distal ends of the first and second collapsible arms; and
an articulating joint, wherein the articulating joint connects the first collapsible arm to the hybrid shaft and the second collapsible arm to the hybrid shaft.

Abstract
A specimen retrieval device may comprise the specimen retrieval bag for retrieval biological materials, a hybrid shaft, a first collapsible arm, and a second collapsible arm. The hybrid shaft may comprise a proximal end and a distal end, wherein the distal end is flexible, and wherein the proximal end is rigid. The first collapsible arm may be located at the distal end of the hybrid shaft, and may include a first portion. The second collapsible arm may be located at the distal end of the hybrid shaft, may include a first portion and a second portion. The second portion of the second collapsible arm may extend distally beyond the first portion of the second collapsible arm. The specimen retrieval bag may have an open end and a closed end, and may be configured to be retained upon the first collapsible arm and the second collapsible arm.
