  • Patent number: 11071582
    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: 20210038293
    Abstract: A surgical instrument includes a handle, and an elongated shaft extending from the handle. An end effector extending from the elongated shaft is in communication with a source of electrosurgical energy and defines an end effector axis. A roll joint couples the end effector to the elongated shaft and includes a first tubular structure extending distally from the elongated shaft and a second tubular structure rotatably coupled to the first tubular structure. The second tubular structure supports the end effector such that the end effector is rotatable about the end effector axis.

  • Publication number: 20200197114
    Abstract: A system and method for using a remote control to control an electrosurgical instrument, where the remote control includes at least one momentum sensor. As the surgeon rotates their hand mimicking movements of a handheld electrosurgical instrument, the movements are translated and sent to the remote controlled (RC) electrosurgical instrument. The surgeon uses an augmented reality (AR) vision system to assist the surgeon in viewing the surgical site. Additionally, the surgeon can teach other doctors how to perform the surgery by sending haptic feedback to slave controllers. Also, the surgeon can transfer control back and forth between the master and slave controller to allow a learning surgeon to perform the surgery, but still allow the surgeon to gain control of the surgery whenever needed. Also, the surgeon could be located at a remote location and perform the surgery with the assistance of the AR vision system.

  • Patent number: 10327834
    Abstract: A method for manufacturing an end effector assembly includes providing first and second jaw members moveable relative to one another about a pivot between a first, spaced-apart position and a second, approximated position. One of the first and second jaw members includes a cavity defined therein and the other of the first and second jaw members includes a stop member configured to be inserted into the cavity. A gap-setting gauge is grasped between the first and second jaw members to define a gap-distance between the jaw members equivalent to a thickness of the gap-setting gauge. The first and second jaw members are set such that the jaw members are prevented from approximation beyond the gap-distance.

  • Patent number: 10136908
    Abstract: A surgical instrument includes a housing and an elongated shaft extending distally therefrom. The elongated shaft includes a proximal portion, a distal portion and a flexible portion supported therebetween. The flexible portion permits pivotal movement of the distal portion of the elongated shaft and an end effector supported thereon. A locking mechanism is operatively associated with the flexible portion of the elongated shaft to selectively impede pivotal motion of the distal portion. The locking mechanism includes a locking coil disposed about an axis defined by the flexible portion of the elongated shaft. A distal end of the locking coil is coupled to the distal portion of the elongated shaft, and a proximal end of the locking coil is rotatable about the longitudinal axis to laterally approximate the locking coil to flexible portion, and thus frictionally engage the flexible portion of the elongated shaft to selectively impede articulating motion thereof.
