The system may further have a second handle that can be moved by a pupil to control the same instrument. Deviations between movement of the handles by the mentor and the pupil can be provided as force feedback to the pupil and mentor handles. The force feedback pushes the pupil's hand to correspond with the mentor's handle movement. The force feedback will also push the mentor's hand to provide information to the mentor on pupil's movements. The mentor is thus able to guide the pupil's hands through force feedback of the pupil handles to teach the pupil how to use the system.

  • Patent number: 9028495
    Abstract: A surgical instrument includes an elongated shaft having a proximal structural member and a proximal drive member that is selectively movable with respect to the proximal structural member. A modular end effector is removably coupled to the elongated shaft, and has a distal structural member and a distal drive member that is operatively coupled to a pair of jaw members. A separable joint is defined between the elongated shaft and the end effector. The separable joint includes laterally prominent and laterally indented portions of each of the proximal and distal structural members and of each of the proximal and distal drive members. The structural members are interlocked to resist longitudinal separation and permit lateral separation. The drive members are movable relative to structural members to move the separable joint to a locked configuration wherein the drive members prohibit lateral separation of the structural members.

  • Publication number: 20150126999
    Abstract: A surgical instrument includes a housing supporting first and second actuators thereon, and an elongated shaft extending distally from the housing. First and second drive members extend through the elongated shaft to operatively couple respective actuators to respective jaw members such that independent manipulation of one of the actuators may induce pivotal movement of an individual jaw member. A locking member is operatively associated with the first and second drive members, and is selectively movable between locked and unlocked positions. When the locking member is in the locked position, the first and second drive members are coupled to one another and move concurrently to drive the jaw members in a bilateral manner. When the locking member is in the unlocked position, the drive members are decoupled from one another and move independently to permit operation of the instrument in a unilateral manner.
