Abstract:
In laparoscopic and thoracoscopic surgery, maintaining clear visualization is crucial for safe and efficient operation. We have developed a new scope warmer/cleaner (Lapahot®) based on "hot-pack" technology. We used our device in 20 consecutive laparoscopic and thoracoscopic cases and compared it with the conventional warm saline method. Lens fogging was not observed in any of the cases, and the cleaning function was comparable to the warm saline method. Moreover, continuous temperature monitoring showed that Lapahot® maintained its temperature much longer than warm saline. Our novel device has the potential to become the new standard for lens defogging and cleaning.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
