A smoke evacuation device that evacuates smoke from a surgical site and filters the smoke from the air. The smoke evacuation device can include a fluid trap for removing moisture from the smoke. The smoke evacuation device can also include a filter with a compression mechanism for compressing a filter medium. The smoke evacuation device can also include features for controlling flow parameters, noise, and vibrations of the device. A remote activation device can also be used to activate the smoke evacuation device upon detection of certain system parameters.

Smoke evacuation device

A system for noise and vibration management of a smoke evacuation system includes a pump that compresses air and produces a pressure differential within an airflow path. The pump may be a sealed, positive displacement pump. The system includes vibration absorption mechanisms disposed between inner and outer housings, as well as on the outside surface of the outer housing. Methods of controlling and regulating a motor of the system to preserve the lifespan of the motor and maintain consistent airflow rates throughout the smoke evacuation system include varying a supply of electrical current to the motor so that it can operate at variable performance levels. Orifices are opened and closed in order to relieve resistance pressures within the airflow path due to clogging and blockages.

Noise and vibration management for smoke evacuation system

An electrosurgical system comprises a return electrode that includes a conductive element and a return conductor that forms a capacitive electrical connection with the conductive element. The conductive element is completely encompassed by one or more pads so that the conductive element is not exposed and so that the return electrode does not include an externally exposed electrical connection.

Piezo nest having a vial track

An instrument includes a body having an interior conduit and a conductor extending within the interior conduit. A shaft extends distally out of the body and is movable between a retracted position and an extended position. A sliding conductor extends within the shaft and a contact portion of the sliding conductor extends between the conductor of the body and an exterior portion of the shaft. An end portion of the contact portion is at least partially disposed within an opening of the shaft. A locking mechanism that selectively secures the shaft in the retracted and extended positions includes a locking nut that is selectively movable between a locked position and an unlocked position and compression flanges with contact pads that flex toward the shaft when the locking nut is in a locked position to secure the shaft in the extended or retracted positions.

Security chip holding apparatus

Surgical devices, systems, and methods are provided for applying monopolar energy and bipolar energy to tissue. In one embodiment, a surgical device is provided with an end effector that has first and second jaws movable between an open position and a closed position, and a conductive member that extends through the end effector. The conductive member has a retracted position in which the conductive member is substantially disposed within the end effector and an extended position in which the conductive member extends at least partially distally beyond the end effector. The conductive member is configured to conduct energy through tissue adjacent thereto when the conductive member is in the extended position. A trigger coupled to the handle is pivotally movable to move the conductive member between the retracted and extended positions.

Devices and methods with monopolar and bipolar functionality

An electrosurgical instrument has dual zone smoke evacuation for providing efficient capture and evacuation of smoke generated during an electrosurgical procedure. A hand piece with a proximal and a distal end is coupled to a front piece having a distal opening leading into an interior conduit. An extendable section is at least partially disposed within the interior conduit and extends distally out of the distal opening of the front piece. The extendable section is selectively translatable within the interior conduit. A negative pressure source enables the capture and evacuation of smoke through both the extendable section and the interior conduit.

Hand-held instrument with dual zone fluid removal

In general, systems, methods, and devices for electrosurgical devices with monopolar and bipolar functionality are provided. In an exemplary embodiment, a surgical device can have bipolar functionality, in which tissue engaged by the device is treated in a bipolar energy delivery mode, and can have monopolar functionality in which tissue engaged by the device is treated in a monopolar energy delivery mode.

Fluid trap

A portable, battery powered electrosurgical wave generator is usable in performing electrically driven medical procedures. The wave generator can be small and lightweight to enable a user to carry and use the wave generator in non-operating room type settings. The wave generator can include a control unit that generates output signals in each of a cutting mode, coagulation mode, and a bipolar mode. The control unit can use a single circuit structure to generate the output signals for the cutting, coagulation, and bipolar modes. The output signals can be generated solely from a voltage produced by an incorporated battery within the generator.

Electrosurgical wave generator

Embodiments of the present invention relate to the field of pressurized fluid delivery devices for use in medical procedures. In particular, a fluid delivery pump comprises at least one compressive member configured to apply a force to a fluid reservoir. The at least one compressive member is associated with a flexible envelope, such that the flexible envelope may move the compressive member. The flexible envelope may be substantially air-tight so that it may be pressurized. When a negative pressure is created inside the flexible envelope, the flexible envelope may change volume, applying a force to the at least one compressive member. The at least one compressive member may then apply a force to the fluid reservoir and the fluid is forced out of the reservoir.

Vacuum assisted irrigation pump

A radio frequency (RF) current sensor for remotely activating a smoke evacuation device in an electrosurgical system includes a sensor body with a cable interfacing sidewall and a retaining member. The cable interfacing sidewall and the retaining member define a retention pocket for receiving a cable communicating RF current. The RF current sensor additionally includes a sensor element for detecting RF current in the cable and a sensor cable in electrical communication with the sensor element. The RF current sensor can operate in at least two modes, depending on whether the cable communicates RF current to a monopolar or bipolar electrosurgical instrument, but regardless of the operation mode, the sensor cable can communicate an activation signal and a current signal derived from the detected RF current to the smoke evacuation device, which activates or adjusts the period of time and/or the smoke evacuation flow rate of a vacuum source.
