Electrosurgical Device Having an Adjustable Length, Methods of Operating an Electrosurgical Device, and Methods of Manufacturing an Electrosurgical Device

A method of manufacturing an electrosurgical device, the method comprising:

• forming a handle having a proximal end and a distal end, wherein the handle defines an interior cavity;
• coupling a shaft to the handle such that the shaft extends from the distal end of the handle and at least a portion of the shaft is in the interior cavity of the handle, wherein the shaft is telescopically movable relative to the handle;
• coupling an electrosurgical electrode to a distal end of the shaft;
• disposing a linear actuator in the interior cavity of the handle;
• and
• coupling the linear actuator to the shaft such that the linear actuator is operable to axially move the shaft relative to the handle.

An electrosurgical device comprising:

• a housing having an interior cavity, wherein the housing has a slit;
• a shaft disposed, at least partially, within the interior cavity of the housing;
• an electrosurgical electrode extending from a distal end of the shaft;
• and
• a roller disposed partially within the interior cavity of the housing, and extending through the slit of the housing to be accessible outside the housing, wherein the roller engages the shaft, such that rotation of the roller causes the shaft and the electrosurgical electrode to move linearly relative to the housing.

A method of operating an electrosurgical device, the method comprising:

• providing an electrosurgical device comprising:
• a housing having an interior cavity, wherein the housing has a slit,
• a shaft disposed, at least partially, within the interior cavity of the housing,
• an electrosurgical electrode extending from a distal end of the shaft, and
• a roller disposed partially within the interior cavity of the housing, and extending through the slit of the housing to be accessible outside the housing,
• wherein the roller engages the shaft, such that rotation of the roller causes the shaft and the electrosurgical electrode to move linearly relative to the housing;
• and
• rotating the roller relative to the housing to cause the shaft and the electrosurgical electrode to move linearly relative to the housing.
