The Laparoshield Laparoscopic Smoke Filtration System is a passive smoke evacuation system which removes particles, cells, virus and odor causing noxious chemicals from surgical smoke generated in laparoscopic procedures while maintaining a clear field of vision. It is indicated for use during any minimally invasive surgery involving insufflation, electrocautery, laser, or ultrasonic scalpel use.
Features and Benefits
- Maintain Continuity of Surgical Procedures. During tissue ablation, smoke accumulates in the peritoneal cavity obscuring the surgeon's vision.1 Interruption of surgical procedures to clear the field of vision can cause delays to re-acquire the pneumoperitoneum and reposition instruments.
- Reduce Odor and Mutagenic Chemicals. Smoke, created in the burning of tissue with both laser and electrocautery, contains toluene, xylene, styrene, acetaldehyde, acrolein, polyaromatic hydro-carbons (PAH's), benzene and formaldehyde. In addition to contributing to the noxious odor of the smoke, these chemicals are known irritants and, in the case of PAH's, benzene and formaldehyde, known carcinogens.2-5 The Laparoshield Filtration System contains activated carbon, which reduces these chemicals and odor in the smoke.
- Remove Cells and Virus. Viable cells and virus exist in electrocautery and laser smoke.6-8 The Laparoshield Filtration System will remove 99.999% of all cells and virus from surgical smoke.
- Easy to Use. The universal luer connector meets ISO standards for leak free connection to the trocar.
- Remove Particles. Surgical smoke from both lasers and electrocautery contains large quantities of particles ranging in size from 10 mm to 1 µm.9 These particles are the size classified as hazardous to breathe, i.e., 0.5 - 5 µm. Studies show both laser and electrocautery plume produce pathologic changes in the lungs of rats and are too small to be filtered by surgical masks.10-11 The Laparoshield Filtration System removes 99.999% of the 0.02 µm MS-2 virus.
- Protect Patients. Surgical smoke is cytotoxic.13 Absorption into the patient's blood, causing elevated methemoglobin and carboxyhemoglobin levels, is also possible.2,14 It can contribute to headaches, double vision, muscle weakness, nausea and vomiting in patients recovering from laparoscopic procedures.14 The Laparoshield Filtration System allows for an efficient evacuation of smoke throughout the surgical procedure, minimizing the patient's exposure to potentially harmful surgical smoke.
- Unobtrusive. A lightweight, low profile construction makes efficient use of materials providing a non-obtrusive, cost-effective solution to laparoscopic smoke removal.
- Easy Presentation into Sterile Field. The Laparoshield Filtration System is packaged and sterilized in a double peel-pouch configuration allowing easy presentation into the sterile field.

Pall Medical Scientific Laboratories testing. Smoke generated using electrocautery on beef liver.
Trial 1 represents the amount of chemical present after filtration of smoke generated in 60 seconds of cautery. Control represents amount of chemical present in smoke after 60 seconds of cautery and no filter. Trial 2 represents the amount of chemical present after filtration of smoke generated in 180 seconds of cautery.
