27. A device to treat an ocular condition, the device comprising:
an outer housing having a proximal end region and a distal end region;
a rotary housing located within the outer housing rotationally fixed to a rotary spindle and rotationally movable relative to the outer housing;
an elongate shaft projecting distally from the distal end region of the outer housing along a central longitudinal axis, at least a distal end region of the elongate shaft being sized for insertion into an eye, wherein the elongate shaft comprises:
an outer shaft having a lumen; and
an inner cutting tube positioned at least partially within the lumen of the outer shaft and movable relative to the outer shaft, a distal end of the inner cutting tube comprising a distal opening defined by a distal cutting surface, wherein a proximal end region of the inner cutting tube is fixedly coupled to the rotary spindle; and
wherein, upon actuation of the device, the rotary housing rotates causing the rotary spindle and the inner cutting tube to rotate around the central longitudinal axis while simultaneously causing axial extension of the inner cutting tube distally along the central longitudinal axis to advance the distal cutting surface through a target tissue forming a tissue slug,
wherein rotary motion of the rotary housing is achieved mechanically via a torsion spring.
