Brief summary
The purpose of this study is to evaluate the safety and effectiveness of using Temperature Controlled Laser Soldering System for soft tissue bonding.
Detailed description
Skin incisions can be closed by a variety of method which create temporary approximation of the wound edges until natural healing process ensue and reach a phase, where it is closed and can sustain the daily tensile forces. The wound closure devices include sutures, staples, tapes, tissue adhesives. The Applied Physics group at the Tel Aviv University has developed a Temperature Controlled CO2 Laser Soldering system for soft tissue bonding. This system includes features that make laser soldering suitable for clinical use. The Temperature Controlled Laser Soldering System is composed of CO2 fiberoptic laser device, Infrared fiber-optic radiometer, a computerized temperature control program, propriety grip device (Clamps) and concentrated Human Albumin as a soldering agent.
Interventions
DEVICETemperature Controlled Laser Soldering
This study had a prospective within-subject design. Patients allocated to laparoscopic cholecystectomy procedure were enrolled. After the completion of the laparoscopic cholecystectomy surgical procedure, 4 trocar port sites were randomly either sutured or laser soldered by employing the temperature-controlled laser soldering system.

Primary
| Measure | Time frame |
|---|---|
| Primary study endpoint will be to establish the safety of using the Temperature Controlled Laser Soldering System for skin bonding and wounds closure. Safety will be established by paucity of serious adverse events and adverse events. | 3 months |
Secondary
| Measure | Time frame |
