1. An endoscopy system comprising:
a sheath comprising a lumen and an opening at a distal-most end of the sheath, a distal portion of the sheath being deformable;
an image sensor disposed within the lumen of the distal portion of the sheath;
an illuminating element disposed within the lumen adjacent to the image sensor;
a working channel disposed within the lumen, the working channel comprising a distensible portion that extends past at least a portion of the image sensor; and
a piezoelectric element sized to fit within the working channel, the piezoelectric element comprises a transducer coupled to a working tip with an intervening wire, the piezoelectric element configured to move the working tip via the wire when electricity is applied to the transducer, the working tip configured to puncture a tissue when the working tip is moved as a result of electricity being applied to the transducer
wherein the transducer is disposed distal of the image sensor when the working tip extends distally beyond the opening at the distal-most end of the sheath.
