Abstract:
1. A tissue removal device, comprising: a handpiece having a housing, the housing having a longitudinal axis, a proximal end including a proximal-most portion, a distal end, and a midpoint along the longitudinal axis, wherein the proximal-most portion of the housing includes one of a cable port and a hose connector; an outer cannula having an outer cannula lumen, a proximal end, a distal end, and an outer cannula opening adjacent the distal end, wherein the opening adjacent the distal end defines a cutting edge for severing tissue; an inner cannula disposed in the outer cannula lumen and reciprocable within the outer cannula lumen, the inner cannula having a longitudinal axis, an inner cannula lumen, a proximal end, an open distal end, a cutting edge at the distal end, a living hinge, a cutting section, and a body section, with the hinge being located between the cutting section and the body section, wherein the cutting section is pivotable when the inner cannula reciprocates within the outer cannula lumen; a tissue collector in fluid communication with the inner cannula lumen; and a motor disposed in the handpiece; wherein the motor is positioned proximal of the housing midpoint along the direction of the housing longitudinal axis.
