SURGICAL INSTRUMENTS AND METHODS FOR PERFORMING TONSILLECTOMY, ADENOIDECTOMY, AND OTHER SURGICAL PROCEDURES
First Claim
1. A surgical instrument, comprising:
- a housing;
a shaft extending distally from the housing, the shaft defining a rectangular cross-sectional configuration and including opposed short sides and opposed long sides;
an end effector assembly including first and second jaw members pivotably coupled to one another and the shaft via a pivot pin extending between the opposed long sides of the shaft, the first and second jaw members movable relative to one another about the pivot pin between a spaced-apart position and an approximated position for grasping tissue therebetween;
a drive plate slidably disposed within the shaft and operably coupled to the end effector assembly such that translation of the drive plate through the shaft and relative to the end effector assembly moves the first and second jaw members between the spaced-apart and approximated positions, the drive plate defining a pair of surfaces disposed within planes extending in parallel orientation relative to the opposed long sides of the shaft;
a knife member slidably disposed within the shaft, the knife member configured to translate through the shaft and relative to the end effector assembly between a retracted position and an extended position wherein the knife member extends at least partially between the first and second jaw members, the knife member defining a pair of surfaces disposed within planes extending in parallel orientation relative to the surfaces of the drive plate and the opposed long sides of the shaft.

Abstract
A surgical instrument includes a housing, a shaft extending from the housing, and end effector, a drive plate, and a knife member. The shaft defines a rectangular configuration. The end effector includes first and second jaw members coupled to one another via a pivot pin extending between long sides of the shaft and movable about the pivot pin between spaced-apart and approximated positions. The drive plate is configured such that translation of the drive plate through the shaft and relative to the end effector assembly pivots the jaw members. The drive plate defines surfaces that are parallel to the long sides of the shaft. The knife member is configured to translate through the shaft and relative to the end effector assembly between retracted and extended positions. The knife member defines surfaces that are parallel to the surfaces of the drive plate and the long sides of the shaft.
