Abstract:
1. A tissue cutting device, comprising: a housing; a cutting member partially supported within the housing, the cutting member defined by an open distal end and an open proximal end, the cutting member operatively connected to an actuator assembly; a hollow non-reciprocating base member partially supported within the housing, the hollow non-reciprocating base member defined by an open proximal end and having a hollow tissue pathway defined between a distal end of the hollow non-reciprocating base member and the open proximal end, having an upwardly extending foot plate disposed on the distal end thereof, the base member configured for selective rotation with respect to the housing; wherein the cutting member is configured for reciprocating movement with respect to the distal end of the hollow non-reciprocating base member; wherein the cutting member is received over the hollow non-reciprocating base member and is configured for selective rotational movement with respect to the housing; wherein a distal end of the cutting member has a cutting element and the distal end of the cutting member and the foot plate cooperates to define a tissue receiving opening; wherein the foot plate defines a contact surface that is configured with a textured surface that serves as a grip to operatively retain material to be cut when the cutting member is moved toward the foot plate; and wherein when the cutting element of the cutting member is moved against the foot plate to sever tissue, the tissue that is severed is delivered through the hollow tissue pathway and out the proximal end of the hollow non-reciprocating base member to exit the housing by application of vacuum to the proximal end of the hollow non-reciprocating base member.
