Controlling the depth of percutaneous applications

摘要

An apparatus for percutaneous application comprising a housing and a percutaneus probe having a sharp end and being disposed within the housing so as to be movable relative to the housing between a stowed position and a deployed position, with at least part of the probe extending out of the housing at the exit portion when the probe is in the deployed position.

According to an embodiment, the housing has an exit portion and an at least partially light emissive portion positioned proximate to the exit portion. The at least partially light transmissive portion is positioned to allow visual access to the exit portion as the probe moves to the deployed position.
