A lancing system can include a device body having a sealing device coupled to a lancing end, a lancing shaft slideably coupled to the lancing end, a lancing spring coupled to the lancing shaft, a release mechanism, a main shaft slideably coupled with a free end of the device body in communication with the release mechanism, a piston coupled to the main shaft, a vacuum spring coupled to the piston, and a shaft coupler having at least two separable portions for removably coupling the lancing shaft to the main shaft. The system can include a lance tool having an insertion portion and a removal portion. A method can include creating a first portion of a vacuum, lancing a surface, and creating a second portion of a vacuum.
