Sumario: | BACKGROUND: Surgical recording has become very important for digestive surgery skill training in the COVID-19 pandemic. In addition to high quality recordings, the directions of vantage points are also important. To assist our vantage point for our camera, we frequently use a laser pointer to increase accuracy in the shooting range. MATERIALS AND METHODS: We recorded surgery more than 2 h with a fixed top-mounted Panasonic HC-V770 camcorder and otherwise with an action-cam Sony FDR. We installed a laser Pointer TaffLED Tactical Red Dot Laser Gun Picatinny Mount Airsoft Rifle HJ 11. We compared focus field video recordings with and without laser pointer guiding. We divided them into four groups: head mounted with, head mounted without, top mounted with and top mounted without. We recorded a total of five digestive surgery cases of superficial, visceral, and deep visceral procedures for each group after adjusting the laser pointer direction to the center of the cameras’ focus. RESULTS: The laser pointer on camcorder Panasonic HC-V770 can assist recording on operation fields to prevent the field of view from being blocked by movement of an object compared to either camera without laser pointer. The head mounted Sony FDR-X3000 action-cam can easily depict surgeon's eye while recording and be controlled by the slightest movement of the surgeon's head by tracking with a red dot. CONCLUSION: From either mounting, the laser pointer aided in focusing the surgical field of view and could increase visibility for surgical recording. |
