Abstract
A medical device includes a shaft having a distal end, a proximal end, and a shaft body extending between the distal end and the proximal end, the shaft body having a longitudinal axis; a first blade fixedly coupled to the distal end of the shaft, wherein the first blade has a first rectilinear planar surface; a second blade in contact with the first blade, wherein the second blade has a second rectilinear planar surface, and wherein the second blade is configured to move in a reciprocating manner in opposite directions that are parallel to the longitudinal axis of the shaft body; and a handle coupled to the proximal end of the shaft; wherein the shaft, the first blade, and the second blade are sized for insertion into a patient.

A medical device, comprising:
- a shaft having a distal end, a proximal end, and a shaft body extending between the distal end and the proximal end, the shaft body having a longitudinal axis;
- a first blade fixedly coupled to the shaft, wherein the first blade has a first rectilinear planar surface;
- a second blade in contact with the first blade, wherein the second blade has a second rectilinear planar surface, and wherein the second blade is configured to move in a reciprocating manner in opposite directions that are parallel to the longitudinal axis of the shaft body;
- and
- a handle coupled to the proximal end of the shaft;
- wherein the first blade and the second blade are sized for insertion into a patient;
- wherein the medical device further comprises a mechanical coupler configured to maintain contact between the first blade and the second blade while allowing the second blade to translate relative to the first blade;
- wherein the handle comprises a user control configured to move the second blade;
- and
- wherein the handle comprises a hand-held portion and a knob rotatable relative to the hand-held portion, the knob configured to rotate the shaft about the longitudinal axis.
A medical device, comprising:
- a shaft having a distal end, a proximal end, and a shaft body extending between the distal end and the proximal end, the shaft body having a longitudinal axis;
- a first blade fixedly coupled to the shaft, wherein the first blade has a first rectilinear planar surface;
- a second blade in contact with the first blade, wherein the second blade has a second rectilinear planar surface, and wherein the second blade is configured to move in a reciprocating manner in opposite directions that are parallel to the longitudinal axis of the shaft body;
- and
- a handle coupled to the proximal end of the shaft;
- wherein the shaft comprises a first elongated member and a second elongated member, wherein the first blade is coupled to the first elongated member, and wherein the second blade is coupled to the second elongated member, and wherein the second elongated member is moveable along the longitudinal axis relative to the first elongated member;
- wherein the second elongated member comprises a proximal member end, and a spherical connector at, or coupled to, the proximal member end;
- wherein the handle comprises a user control mechanically coupled to the spherical connector;
- and
- wherein the spherical connector is configured to allow the user control to actuate the second blade, while also allowing the second elongated member to rotate about the longitudinal axis relative to the user control.
