Adapter direct drive with manual retraction, lockout and connection mechanisms
First Claim
1. A surgical device adapter for coupling an end effector to a handle assembly, the surgical device adapter comprising:
- a housing;
a drive mechanism disposed within the housing and couplable to the handle assembly and the end effector, the drive mechanism including a first drive screw configured to be coupled to the end effector to actuate the end effector; and
a drive coupling assembly coupled to the housing and selectively couplable to the handle assembly, the drive coupling assembly including a first drive gear mechanically engaged to the first drive screw and a retraction assembly selectively couplable to the drive mechanism such that rotation of the drive coupling assembly about a longitudinal axis defined by the surgical device adapter and relative to the housing actuates the drive mechanism, wherein the retraction assembly includes;
a lock rocker pivotally coupled within the drive coupling assembly; and
a lock ring rotatable about the longitudinal axis and relative to the drive coupling assembly, wherein rotation of the lock ring actuates the lock rocker to meshingly-engage the lock rocker with the first gear.

Abstract
A surgical device adapter for coupling an end effector to a handle assembly is disclosed. The surgical device adapter includes: a housing; a drive mechanism disposed within the housing and couplable to the handle assembly and the end effector; and a drive coupling assembly coupled to the surgical device adapter and selectively couplable to the handle assembly, the drive coupling assembly including a retraction assembly selectively couplable to the drive mechanism such that rotation of the drive coupling assembly about a longitudinal axis defined by the surgical device adapter and relative to the housing actuates the drive mechanism.

6. A surgical device comprising:
-
an end effector including a first jaw and a second jaw moveable relative to the first jaw; a handle assembly including at least one motor mechanically coupled to the end effector; and an adapter assembly removably coupled to a proximal end of the end effector and a distal end of the handle assembly, the adapter assembly including; a housing; a drive mechanism disposed within the housing and configured to couple the at least one motor to the end effector; and a drive coupling assembly including; a housing coupled to the housing of the adapter assembly and selectively couplable to the handle assembly; a first drive gear disposed within the housing; and a retraction assembly coupled to the housing of the drive coupling assembly and selectively couplable to the drive mechanism such that rotation of the drive coupling assembly about a longitudinal axis defined by the adapter assembly and relative to the housing of the adapter assembly actuates the drive mechanism, the retraction assembly including; a lock rocker pivotally coupled within the drive coupling assembly; and a lock ring rotatable relative to the drive coupling assembly, wherein rotation of the lock ring engages the lock ring with the lock rocker to meshingly-engage the lock rocker with the first gear. - View Dependent Claims (7, 8, 9)
