Adapter direct drive with manual retraction, lockout, and connection mechanisms for improper use prevention

ADAPTER DIRECT DRIVE WITH MANUAL RETRACTION, LOCKOUT, AND CONNECTION MECHANISMS FOR IMPROPER USE PREVENTION A surgical device adapter (200) for coupling an end effector (300) to a handle assembly (100) is provided. The surgical device adapter (200) includes a housing and a drive mechanism disposed within the housing and couplable to the handle assembly (100) and the end effector (300). The surgical device adapter (200) also includes a drive coupling assembly (210) coupled to the surgical device adapter (200) and selectively couplable to the handle assembly (100). The drive coupling assembly (210) includes retraction assembly (280) movable from a first configuration to a second configuration, wherein in the first configuration the retraction assembly (280) is disengaged from the drive mechanism and in the second configuration the retraction assembly (280) is engaged with the drive mechanism and prevents coupling of the handle assembly (100) to the surgical device adapter (200). 118" ii 30 Fig. 1 1 08b 122 108a 103 Fig. 2 -114242 282 236 Fig. 3
