Abstract:
1. An endoscope for removing tissue at a surgical site, comprising: an elongated tubular body having a distal end and a proximal end, the distal end insertable within a mammalian cavity of a patient, the proximal end configured to remain outside the mammalian cavity of the patient; an instrument channel defined within the elongated tubular body and extending between a first opening at the proximal end and a second opening at the distal end, the instrument channel sized and configured to receive a removable surgical cutting assembly that defines an aspiration channel configured to fluidly couple, at a proximal end of the surgical cutting assembly, to a suction source to remove material entering the endoscope via a distal end of the surgical cutting assembly; a flexible torque delivery component configured to deliver torque generated by a torque generation component to an inner cannula of the surgical cutting assembly to cause the inner cannula to move relative to an outer cannula of the surgical cutting assembly to resect material entering the surgical cutting assembly, the flexible torque delivery component extending from the proximal end towards the distal end of the elongated tubular body; and a coupling component integral to the distal end of the elongated tubular body and positioned adjacent to or surrounding the instrument channel is rotatably coupled to the flexible torque delivery component to provide the torque delivered by the flexible torque delivery component to a coupling member of the surgical cutting assembly and configured to cause the coupling member of the surgical cutting assembly to move the inner cannula relative to the outer cannula upon actuation of the flexible torque delivery component.
