In examples, a method of operating a surgical device comprises disengaging an obturator from a funnel portion of a cannula; removing a shaft portion of the obturator from a cannula lumen of the cannula; disengaging a seal cartridge from the funnel portion of the cannula; and removing the seal cartridge from the funnel portion after removing the shaft portion of the obturator from the cannula lumen.

Cannula assembly

A system configured to control operation of an ultrasonic surgical instrument is disclosed. The system comprises a generator configured to generate a signal, and a computer communicably coupled to the generator. The computer is configured to receive a first set of variables corresponding to a first signal at a first power level of the instrument, evaluate the first set of variables with a model to generate a first output, wherein the first output comprises a value between the first set of variables and a condition set, and wherein the condition set comprises a plurality of conditions that correspond to a plurality of responses, determine the first output meets a first threshold value for a first condition; determine a first response corresponding to the first condition, wherein the first response is a second power level for the instrument, and transmit the second power level to the generator for a second signal.

Switch arrangements for ultrasonic surgical instruments

A trocar assembly can include a cannula, a seal cartridge, and an obturator. The seal cartridge is configured to be releasably coupled to the cannula and to be disposed at least partially within the cannula in a coupled configuration of the seal cartridge. The obturator is configured to directly latch to the cannula and to extends through the cannula and the seal cartridge in a coupled configuration of the obturator.

Described herein include various embodiments of a tool assembly for performing endoscopic surgery that can be used manually and/or with a robotic surgical system. The tool assembly can include a shaft assembly that extends from a housing of the tool assembly. A distal end of the shaft can include an end effector that includes a clamp arm pivotally coupled to a blade for cutting and/or sealing tissue. Pivoting of the clamp arm between the open and closed configurations can be caused by movement of a yoke that is slidably disposed within the housing of the tool assembly. For example, the yoke can be caused to move by one or more outputs (e.g., a manual output, a rotary output, and/or a linear mechanical output). Furthermore, some tool assembly embodiments can include a biasing system that biases the yoke such that the clamp arm is in the open configuration. In some embodiments, the tool assembly can be configured for tissue spread dissection using the clamp arm and blade.

Ultrasonic robotic tool actuation

Aspects of the present disclosure are presented for a surgical instrument for cutting and sealing tissue. In some embodiments, the surgical instrument includes a handle assembly, a shaft, and an end effector. The end effector may include: a blade that vibrates at an ultrasonic frequency, a shielded portion enclosing a back edge of the blade, a high-friction surface coupled to the shielded portion and positioned between the shielded portion and the back edge of the blade. A space is defined between the high-friction surface and the back edge of the blade when the end effector is in a cutting configuration. In a sealing configuration, the high-friction surface contacts the back edge of the blade, which generates heat based on ultrasonic vibrations of the blade rubbing against the high-friction surface. The shielded portion can coagulate bleeding tissue based on heat transfer from the high-friction surface to the shielded portion.

Translatable outer tube for sealing using shielded lap chole dissector

A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, and an end effector. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The ultrasonic blade includes a recess region having a plurality of recesses. The recess region is tapered such that the cross-sectional area of the recess region decreases along the length of the recess region. The ultrasonic blade is also curved such that a central longitudinal axis of the ultrasonic blade extends along a curved path. A reference circuit is used to account for voltage drops of unknown values during operation of the surgical apparatus.

Ultrasonic device for cutting and coagulating

Ultrasonic surgical instruments including a handle housing, a switch frame, and a switch assembly are disclosed. The switch assembly may include a first switch arrangement movably supported on a distal portion of the handle housing and selectively movable relative to a first switch contact supported by the switch frame. The switch assembly may further include a second switch arrangement including a right switch button movably supported on a right side of the handle housing and selectively movable relative to a right switch contact supported by the switch frame, and a left switch button movably supported on a left side of the handle housing and selectively movable relative to a left switch contact supported by the switch frame. The first and second switch arrangements may be configured to be selectively actuatable by a single hand supporting the handle housing.

Surgical systems and methods are provided for controlling actuation and movement of various surgical devices.

Electrically-powered surgical systems providing fine clamping control during energy delivery

Methods and devices are provided for various insufflation sealing approaches for a trocar. For example, a trocar is provided that has a housing and a cannula extending therefrom. The housing and the cannula have a tool pathway extending therethrough for receiving a surgical tool, and the housing has an insufflation port therein. A variety of seal elements are provided that seal the insufflation port to prevent fluid flow into the port. The port and seal elements are configured to have a reduced profile to prevent interference between the trocar and a tissue surface during use.

Trocar with reduced profile

Electrically-powered surgical systems employing variable compression during treatment

Systems and methods are provided for coupling a robotic surgical tool with a tool driver of a robotic surgical system via a sterile barrier disposed between the tool and the tool driver. The sterile barrier can have a housing configured to accommodate proximal portions of a plurality of actuation members of the tool driver when the sterile barrier is coupled to the tool driver. The housing can have at least partially disposed within it substantially cylindrical, longitudinally expandable bellows, each being configured to encompass and mate with a proximal portion of a corresponding one of the plurality of actuation members. In some cases, the sterile barrier can have a plurality of sterile barrier couplers each having a first portion configured to engage with an actuation member of a tool driver, and a second portion configured to engage with a tool actuation member of a surgical tool.

Methods and systems for coupling a surgical tool to a tool driver of a robotic surgical system

Methods and devices are provided for attaching a trocar to a surgical arm. For example, a surgical system is provided that has a trocar with a housing and a cannula extending distally from the housing. The housing and the cannula have a tool pathway extending therethrough for receiving a tool. The system also has a trocar support that is configured to be mounted on a distal end of a surgical robotic arm. The trocar is configured to couple to the trocar support through a variety of engagements, such as engaging the trocar in a first configuration that allows free movement of the trocar relative to the trocar support and in a second configuration in which the trocar is locked in a fixed position relative to the trocar support.
