A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.

A surgical instrument connectable to a surgical energy module that is configured to provide a first drive signal at a first frequency range for driving a first energy modality and a second drive signal at a second frequency range for driving a second energy modality is provided. The surgical instrument can comprise a surgical instrument component configured to receive power from a direct current (DC) power source, an end effector, and a circuit. The circuit can be configured to convert the first electrical signal to a DC voltage, apply the DC voltage to the surgical instrument component, and deliver the second energy modality to the end effector according to the second drive signal. Alternatively, the circuit can be disposed within a cable assembly configured to connect the surgical instrument to the surgical energy module.

A modular energy system including a header module configured to removably connect to an energy module. The energy module can comprise a port configured to deliver one or more energy modalities to a surgical instrument connected thereto. The header module can comprise a display screen configured to display a user interface. The header module can further include a control circuit configured to detect attachment of energy modules to the modular energy system and control the display of the user interface to display UI portions for each connected module and reconfigure the displayed UI portions to accommodate the new UI portions as additional energy modules are connected to the modular energy system.

An electrosurgical handheld device and also a contact body for an electrosurgical handheld device, with which both the required cleanliness and the necessary safety can be obtained. This is achieved by the fact that a contact body for an electrosurgical handheld device for receiving an optical guide and for coupling at least one electrical contact of an electrode instrument of the handheld device has an RF cable, which is fixedly connected to the contact body. By way of this RF cable, an RF voltage can be applied to the electrode instrument via the at least one electrical contact. The other end of the RF cable can be connectable to an RF generator.

An apparatus configured to deliver electrical energy to energize an end effector coupled via a clevis to a shaft of a medical instrument comprises an electrical transmission conduit configured to extend along the shaft from a proximal portion to a distal portion and configured to deliver electrical energy to energize the end effector, and a connector assembly configured to couple to the end effector. The connector assembly comprises an electrically conductive contact portion configured to electrically couple the electrical transmission conduit to the end effector, the electrically conductive contact portion defining a pivot surface about which the end effector is rotatable in a coupled state of the connector assembly to the end effector; and an electrically insulating member configured to electrically insulate the end effector from the clevis in a coupled state of the connector assembly to the end effector.

A method and apparatus for providing hand-mounted surgical tools is provided. The apparatus includes a housing configured to be mounted to a body of a user. The apparatus also includes an optical source to generate a first optical signal in an absorption spectrum of a biocompatible fluorescing dye (BFD). The apparatus also includes an optical detector to detect a second optical signal in an emission spectrum of the BFD. The apparatus also includes a processor to receive a signal from the optical detector that indicates that the second optical signal was detected by the optical detector. The processor is further configured to cause the apparatus to transmit a signal to a non-visual feedback device to cause the non-visual feedback device to output non-visual feedback to the user that the second optical signal was detected by the optical detector.

A flow controllable type suction and irrigation device includes: a handle having an installation space therein; a cannula provided with a conductive tube and an insulating protective tube, the conductive tube extending in a forward direction of the handle to be inserted into the abdominal cavity of a patient and being coupled to an electrode for surgery, the insulating protective tube being disposed to surround the conductive tube; and a suction supply unit provided to the handle and supplying an irrigation fluid to the cannula or suctioning blood or contaminants from the abdominal cavity of the patient through the cannula.

An electrosurgical smoke evacuation pencil includes a handle housing having a proximal end portion and a distal end portion, the handle housing defining a first lumen therethrough. The electrosurgical pencil also includes a nozzle disposed within the first lumen and defining a second lumen, the nozzle being movable relative to and within the handle housing and extending proximally past the proximal end portion of the handle housing. The electrosurgical pencil may further include a swivel connector coupled to the distal end portion of the handle housing, the swivel connector configured to couple to a suction source. The electrosurgical pencil includes a hub assembly securedly disposed within the second lumen, the hub assembly including a conductive tube configured to couple to a source of electrosurgical energy, and an electrode slidably disposed within the conductive tube, the electrode being movable relative to and within the conductive tube.

The present disclosure provides catheters for electroporation systems. One catheter includes a plurality of catheter electrodes disposed along a portion of a distal end of the electroporation catheter. The plurality of catheter electrodes includes a plurality of first type catheter electrodes adapted for use with an electroporation generator during an electroporation procedure and a plurality of second type catheter electrodes adapted for use with an electroporation generator during an electroporation procedure and for use with a diagnostic subsystem. The plurality of first type catheter electrodes is positioned at a distal end of the electroporation catheter. Each second type catheter electrode is adjacent another second type catheter electrode.

An apparatus comprises an electrically power surgical instrument having a handle assembly. The apparatus also comprises a communication device positioned within the handle assembly. The communication device is operable to communicate with at least a portion of the electrically powered surgical instrument. The apparatus further comprises an external device in wireless communication with the communication device. The external device is operable to receive information from the communication device and the external device is operable to provide an output viewable to the user.
