A surgical instrument comprising a jaw assembly is disclosed. The surgical instrument further comprises a motor-driven drive system configured to open the jaw assembly. The surgical instrument also comprises a control system configured to control the drive system and, also, control a power supply system configured to supply electrical power to electrodes defined in the outer surface, or outer surfaces, of the jaw assembly. In use, the surgical instrument can be used to apply mechanical energy and electrical energy to the tissue of a patient at the same time, or at different times. In certain embodiments, the user controls when the mechanical and electrical energies are applied. In some embodiments, the control system controls when the mechanical and electrical energies are applied.

Devices, systems, and methods for a robot-assisted surgery. Navigable instrumentation, which are capable of being navigated by a surgeon using the surgical robot system, and navigation software allow for the navigated placement of interbody fusion devices or other surgical devices. The interbody implant navigation may involve navigation of access instruments (e.g., dilators, retractors, ports), disc preparation instruments, trials, and inserters.

A surgical tool for use with a robotic system that includes a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to robotically-generate output motions. A drive system is configured to interface with a corresponding portion of the tool drive assembly for receiving the robotically-generated output motions and applying the output motions to a drive shaft assembly which is configured to apply control motions to a surgical end effector operably coupled thereto. A manually-actuatable control system operably interfaces with the drive shaft assembly to facilitate the selective application of manually-generated control motions to the drive shaft assembly.

The present disclosure provides handheld adapters allowing the use of robotic surgical instruments during standard laparoscopic phases. The handheld adapter includes a plurality of receptacles for engaging with a plurality of engagers of the surgical instrument to thereby actuate an end-effector of the surgical instrument in the close degrees of freedom via a plurality of force transmitting elements upon actuation of a trigger. The handheld adapter further includes a spring coupled to the plurality of receptacles and configured to provide a predetermined tension on the plurality of force transmitting elements, such that upon release of the trigger, the spring causes movement of the plurality of receptacles, which causes movement of the respective engagers to thereby actuate the end-effector in the open degree of freedom.

A handheld focused extracorporeal shock wave therapy (f-ESWT) device includes a plurality of piezoelectric elements, a power supply circuit, and a plurality of driver circuits. The piezoelectric elements are each configured to generate an individual shock wave. The power supply circuit is configured to output a first DC voltage and a second DC voltage. The first DC voltage greater than the second DC voltage. The driver circuits are each operably connected to the first DC voltage, the second DC voltage, and to a corresponding piezoelectric element of the plurality of piezoelectric elements. Each driver circuit includes a switching element electronically configurable in an open state and in a closed state. When the switching element is in the open state, the first DC voltage and the second DC voltage are applied to the corresponding piezoelectric element to pre-charge the corresponding piezoelectric element with a DC pre-charge voltage having a first polarity.

A surgical device includes an adapter assembly that selectively interconnects a loading unit and a device housing. The adapter assembly includes a drive converter assembly for interconnecting a rotatable drive shaft and an axially translatable drive member of the loading unit. The drive converter assembly converts and transmits a rotation of the rotatable drive shaft to an axial translation of the axially translatable drive member of the loading unit. The drive converter assembly includes a drive element, a drive nut, and a distal drive member. The drive element defines a longitudinal axis. The drive nut is disposed about the longitudinal axis, and the distal drive member is disposed along the longitudinal axis.

Methods for selectively attaching a shaft assembly to a handle of a surgical instrument and an arm of a surgical robot are disclosed.

Methods and systems for preparing a bone for a cementless joint implant are described. A first bone removal operation is performed using a burring device that has a first plurality of settings. The settings for the burring device are adjusted to a second plurality of settings, and a second bone removal operation is performed using the burring device. The adjustment to the settings may allow a surgeon to perform bulk bone removal in the first instance and fine bone removal in the second instance. The process of adjusting and performing subsequent bone removal operations may be performed any number of times during the bone preparation process. The adjustments to the settings may be received automatically from a computer-assisted surgical system, manually entered by a medical professional, or a combination of the two.

A handheld electrosurgical instrument is disclosed, which comprises an upper lobe and a lower lobe, which join at and extend from a narrow neck region substantially perpendicular to one another. The instrument typically includes a surgical tool extending from a distal portion of the upper lobe. The tool may be modular, and the instrument may accommodate any of a plurality of different types and configurations of surgical tools.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.
