1. A medical device, comprising:
a plurality of links movably coupled to one another, the plurality of links including a proximal link and a distal link having an opening, the proximal link and the distal link are configured to move relative to one another between a longitudinally extended configuration and a longitudinally compressed configuration;
a lumen extending through the plurality of links, the lumen is configured to receive a tool through the plurality of links, and the tool is configured to extend outward from the lumen via the opening at the distal link; and
a biasing mechanism extending through the plurality of links and terminating at the distal link, the biasing mechanism configured to push the distal link distally relative to the proximal link, and toward the longitudinally extended configuration;
wherein in the longitudinally extended configuration, the medical device has a first length and a first rigidity, and gaps between the plurality of links such that each link of a pair of adjacent links of the plurality of links is longitudinally separated from the other link of the pair by one of the gaps, wherein the plurality of links are movable in a lateral direction and a linear direction relative to one another due to the gaps; and
wherein in the longitudinally compressed configuration, the medical device has a second rigidity that is different than the first rigidity, and a second length that is different than the first length, wherein the gaps between the plurality of links are removed such that each link of a pair of adjacent links of the plurality of links contacts the other link of the pair, and the plurality of links are immovable in the lateral direction and the linear direction relative to one another due to removal of the gaps.
