The Centers for Disease Control and Prevention (CDC) describes devices as non-critical, semi-critical and critical. Endoscopy is in the semi-critical category, and biopsy forceps are considered to be critical. It was reported that gastrointestinal endoscopy revealed the spread of infection factors such as Helicobacter pylori, Salmonella, Pseudomonas aeruginosa, Xanthomonas and Hepatitis B and Hepatitis C virus. The sterility of the device that maintains the biopsy / aspiration channel through the GI endoscope: endoscopy, attachment treatment, endoscopy kit and gastrointestinal tract are not sterile.
Disinfection and re-use of disposable biopsy clamps in any significant way to impair their function or to significantly increase the risk of infection One-time accessories offer more variety, complexity and practicality. When the equipment is difficult to reprocess, the cost burden they may carry when they contain features that prove costly additional costs, or when their unit costs are close to the cost of re-processing, such as biopsy pliers, with the purchase of reuse substitutes Accepted. Smaller units may tend to be independent of the ease of disposable accessories of relative cost issues, while large, large capacity units may require more careful assessment of cost data to sustain sustainable practices.
It was found that the disposable biopsy force was reliable and consistent when taking a good size of the biopsy specimen and prevented the indirect transmission of infection during endoscopy.7 The post-processing procedure could cause damage to the wearing parts. Disposable biopsy pliers are still contaminated after reprocessing.6,7 In many cases, there is no proper assessment of the real costs and the ease / difficulty of implementing the institutional reuse plan. It is important to remember that the disposable biopsy forceps disrupt the mucosal barrier and contact with the patient's blood flow.1 In a study conducted by the FDA's Office of Science and Technology using three types of tweezers, the researchers found that residual water rinse, Agents and enzymes after ultrasonic washing and water, retained in the equipment. This can not adequately dry the chamber of the device may reduce the sterilization effect .14 Reusable biopsy clamps include more durable stainless steel cups than disposable biopsy calipers; handle and other components are resistant to heat, designed for repeated use and strict cleaning And steam sterilization. The reusable biopsy forceps have special ports for cleaning the liquid through the chamber and cleaning the internal parts.
