Application of Novel CO2 Laser-Suction Device

Abstract

Background Development of the flexible CO2 fiber has presented new opportunities for the use of precision laser cutting in cranial procedures. The efficacy of the CO2 scalpel is further enhanced by combining it with a fluid removal suction capability. Objectives We report our experience with a novel CO2 laser-suction device. Methods The novel laser-suction device was designed in conjunction with OmniGuide Inc. (Cambridge, Massachusetts, USA). We performed a case review of its use in firm tumors that were resistant to resection by bipolar, suction, and ultrasonic aspirator. Results The laser-suction device was applied in three tumors where resection with ultrasonic aspiration failed. Tumor resection using the laser-suction device was successful in all three cases. There were no complications related to the laser-suction device. There were no instances of intraoperative device malfunction. Discussion The CO2 laser combined with suction is a useful instrument for resection of firm tumors that prove to be resistant to ultrasonic aspiration. We also find it to be useful in settings where precise tissue incisions are desired with minimal manipulation. In our experience, the surgical efficiency of the CO2 laser is improved by the laser-suction device. This device allows the surgeon to utilize a suction device and laser in a single hand and enables concurrent use of bipolar electrocautery without repeated instrument changes.

Nanoparticle-Mediated Cavitation via CO2 Laser Impacting on Water: Concentration Effect, Temperature Visualization, and Core-Shell Structures

“…A compound interface 39 might be designed with various liquids to attain more sophisticated structured cavitation with promising functionalities, such as the separation and selection of liquid phases, or the delivery of targeted liquid. Although complicated liquid structures can be generated by other approaches such as a microcapillary device 40 , the structured cavitation here might be particularly applicable for laser-related technological applications, such as CO 2 -laser surgery 14,15 , and the precise manipulation of microstructures in materials science 41 . Moreover, the novel core-shell cavitation together with the recently reported conical interfaces 42 might inspire more future studies on the compound interface of two immiscible fluids impacted by a laser beam and the subsequent diverse patterns and structures.…”

“…In particular, lasers impacting on liquids, ranging from a single droplet 11,12 to soft biological tissues 13 , can generate vapor explosions and cavitation. Due to the intense laser-tissue interaction, lasers offer the potential to precisely manipulate or locally destroy biological tissues for many clinical applications including lithotripsy, tumor removal and neurosurgery 13–15 . Specifically, an ultrafast infrared laser can be selectively absorbed by water in the tissue to generate a rapid ablation or cutting process, holding promise for minimally invasive surgery down to the single-cell level 16 .…”

Development of Cutting and Suction Device with Twist Blade Screw for Minimally Invasive Surgery: Evaluation of Suction Performance

“…For this purpose, devices have been developed as surgical instruments that are capable of simultaneously resecting and removing body tissue, such as the CUSA system (Integra LifeSciences Corp., New Jersey, USA) [ 2 ] and Sonopet (Stryker Corp., Michigan, USA) [ 3 ]. Furthermore, research and development, of devices such as one combining a CO 2 laser and a negative pressure suction tube [ 4 ] and a suction tube with an electric scalpel function in itself [ 5 ] has been performed. These devices also use negative pressure as their suction method.…”
