Virat Enterprises - Laparoscopic Hassan Trocar 5mm Reusable Instruments.The Laparoscopic Hassan Trocar (5mm) is a specialized trocar used in laparoscopic surgeries, particularly for open (Hasson) technique entry. Unlike standard trocars, it is designed for situations where a safer, controlled entry into the abdominal cavity is necessary. Here are the primary uses of the 5mm Hassan trocar:* Open Laparoscopic Entry (Hasson Technique)The Hasson technique is used for initial entry into the abdominal cavity, especially in patients with prior surgeries or when safety is a concern (e.g., to avoid injuries to internal organs or large vessels).The 5mm size allows for minimal incisions while maintaining a reliable port for laparoscopic instruments.In this technique, the surgeon makes a small incision, manually opens the abdominal wall, and places the blunt trocar under direct vision, avoiding the "blind" entry associated with traditional sharp trocars.
