Surgical instrument with stamped double-flange jaws and actuation mechanism
First Claim
1. A surgical instrument, comprising:
- a housing;
a drive rod extending from the housing and including a generally u-shaped profile along at least a portion of a length of the drive rod; and
a pair of jaw members, at least one of the pair of jaw members operably coupled to a distal portion of the drive rod by a cam pin, at least one of the jaw members defining a cam slot configured to receive the cam pin such that longitudinal movement of the drive rod translates the cam pin through the cam slot to move at least one of the pair of jaw members relative to the other one of the pair of jaw members.

Abstract
A surgical instrument includes a housing that supports an elongated shaft. A selectively movable drive rod extends through the elongated shaft and carries a cam pin in a longitudinal direction. An end effector for surgically treating tissue is supported by the elongated shaft and includes upper and lower jaw members pivotally coupled to one another about a pivot axis. The upper jaw member includes a first pair of laterally spaced flanges, and the lower jaw member includes a second pair of laterally spaced flanges defining a camming slot for engaging the cam pin. The flanges are arranged in an offset configuration where one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.

28. A surgical instrument, comprising:
-
a housing; a drive rod extending from the housing and including a generally u-shaped profile along at least a portion of a length of the drive rod, the drive rod including two opposing sidewalls connected by a connector portion to define the generally u-shaped profile; a pair of jaw members, at least one of the pair of jaw members operably coupled to a distal portion of the drive rod such that longitudinal movement of the drive rod moves at least one of the pair of jaw members relative to the other one of the pair of jaw members; and an overfold portion disposed opposite the connector portion and extending from one of the two opposing sidewalls. - View Dependent Claims (29)

30. A surgical instrument, comprising:
-
a housing; an elongated shaft coupled to the housing and defining a longitudinal axis; a pair of opposing jaw members, at least one of the pair of opposing jaw members disposed at a distal portion of the elongated shaft, at least one of the pair of opposing jaw members defining a cam slot; and a drive rod having a generally u-shaped profile along at least a portion of a length of the drive rod and configured to move longitudinally within the elongated shaft to translate a cam pin through the cam slot to move at least one of the jaw members relative to the other jaw member.
