Abstract

A surgical instrument (102) comprises a non-rotating positioning tube (100) having at least one lumen. A blade shaft (105) (which may be a hollow tube ) passes through the lumen and one or more blades (106, 107) are attached to the distal end (115) of the blade shaft (105). The blades (107) have a non-cutting position in which they are retracted so that their diameter is roughly equivalent to the diameter of the lumen and a cutting position in which the blades extend radially outwards beyond the lumen diameter. The blades (107) are moved between the non-cutting position and the cutting position by sliding the blade shaft (105) relative to the tube (100). During a cutting procedure, the blade shaft (105) and the attached blades (107) are rotated while the tube (100) remains fixed. The instrument (102) may also be modular in construction with a main module and additional modules that are interchangeable. These additional modules can include an excision module for removing tissue and a treatment module for applying various therapeutic materials to the surgical site.
