laparoscopic insufflator
Medical device that delivers CO2 gas into the peritoneal cavity to create pneumoperitoneum during laparoscopic procedures.
Full Definition
A specialized medical device that controls the flow, pressure, and volume of CO2 gas delivered into the peritoneal cavity during laparoscopic surgery. The insufflator maintains optimal visualization by creating and sustaining pneumoperitoneum while monitoring intra-abdominal pressure to prevent complications. Modern insufflators feature safety mechanisms including pressure alarms, flow rate controls, and automatic shutoff systems. The device is essential for creating the working space necessary for safe laparoscopic visualization and instrument manipulation.
Usage
Usage note: Always specify pressure settings and flow rates when mentioned in operative documentation. Distinguish from other gas delivery devices used in surgery.
In Context
- "The surgeon requested that the insufflator pressure be reduced to 10 mmHg for better patient tolerance." — Operative report
- "Equipment checklist must include verification of insufflator flow rate and pressure settings before patient positioning." — Surgical protocol
