LIGHTING DEVICE FOR HANDHELD SURGICAL INSTRUMENT WITH SMOKE EVACUATION SYSTEM CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and the benefit of U.S. Non-provisional Application No. 16/918,449, filed July 1, 2020, and is a Continuation-In-Part of U.S.
Application Serial No. 16/519,744 filed July 23, 2019, the disclosures of which are herein incorporated by reference in their entireties.
BACKGROUND OF THE INVENTION 1. Field of the Invention The subject invention is directed to surgical instrumentation, and more particularly, to a battery powered lighting device used with a handheld electrosurgical instrument, which includes a smoke evacuation system. 2. Description of Related Art In medical practice, lighting devices are used to direct light at a specific area being operated on or examined. For example, lighting devices can be used in conjunction with a handheld electrosurgical device, such as a BOVIE® pencil, which is typically used to incise tissue during a surgical procedure.
Some instruments known in the art include an integral light source, but these devices are generally expensive and relatively bulky. Cordless and corded lighting devices for surgical tools are also known in the art, but these can also add bulk, preventing a user from manipulating the tool with precision or in confined spaces.
Other instruments known in the art include an integral smoke evacuation conduit, but these devices are generally expensive and provide usability challenges due to added bulk that impacts ergonomics.
Additionally, many lighting devices, especially corded devices and overhead lights, require constant repositioning, are assistant-dependent to hold or re-position, and - 2 - 92477014v. can be disruptive to a surgical field. Furthermore, corded lighting devices, as well as light sources that are integrated into a tool can become hot, burning the user and/or patient, and possibly even causing a fire.
Headlights can be used as an alternative to a lighting device during a surgical procedure. However, similar to lighting devices, headlights are bulky, commonly require cables to connect to a power source, require constant readjustment, and can pose a potential safety hazard. Moreover, being worn on the head of the surgeon, they are at a distance from the surgical field, decreasing their effectiveness, and they can cause fatigue and strain if worn for an extended period of time.
It is known that when handheld lighting devices, overhead lights and/or headlamps are employed during a surgical procedure, the hands/tools of the surgeon can block the light and cast a shadow on the surgical site, which is undesirable. Those shadows require the user to reposition the lighting sources regularly, and can even require the surgeon to move their head to try to angle the headlamp towards the surgical site differently.
A particularly useful battery powered lighting device designed for attachment to a handheld electrosurgical device, and in particular, for use with a BOVIE® pencil, is disclosed in commonly assigned U.S. Patent No. 9,851,060, the disclosure of which is herein incorporated by reference in its entirety. This device overcomes the deficiencies of the prior art lighting devices described above.
The use of a handheld electrosurgical device, such as a BOVIE® pen to incise tissue, typically creates surgical smoke when energy is imparted to tissue cells during surgery. The heat from the energy vaporizes the intracellular fluid, which increases the pressure inside the cell and eventually causes the cell membrane to burst. When this happens, a plume of smoke containing mostly water vapor is released into the operating 25 - 3 - 92477014v. room. At the same time, the heat chars the protein and other organic matter within the cell, releasing contaminants, such as carbonized cell fragments and gaseous hydrocarbons.
These small particles and gases are potentially hazardous if inhaled. If they are not evacuated from the surgical site nearest to the location where the surgical smoke is created, they can become airborne and inhaled. This has led to the development and use of smoke evacuation systems during surgical procedures. A smoke evacuator is basically a vacuum pump with one or more filters designed to remove surgical smoke and aerosol from an operative site and filter out contaminants. In addition, they may return filtered air to the operating room.
Given the increasing need and desire for surgical evacuation systems in operating rooms, the inventors have determined that it would be advantageous to incorporate such a system directly into a battery powered lighting device used with a handheld electrosurgical instrument. The subject disclosure presents several new and useful embodiments of a battery powered lighting device for use with an electrosurgical instrument, such as a BOVIE® pencil, which incorporates a smoke evacuation system. - 4 - 92477014v.
