Spülkanülen

Spülkanülen, also known as flushing cannulas or irrigation needles, are medical instruments designed for introducing fluids into a body cavity or for washing out substances. They typically consist of a hollow tube with a blunt or rounded tip, often featuring multiple side openings instead of a single terminal opening. This design helps to distribute the irrigating fluid more evenly and gently, preventing excessive pressure or damage to delicate tissues.

These cannulas are commonly used in various medical and dental procedures. In surgery, they can be employed to irrigate surgical sites, remove debris, or deliver medications directly to an area. In dentistry, particularly in endodontics, spülkanülen are crucial for flushing the root canals during cleaning and shaping procedures, ensuring thorough disinfection and removal of debris. They are also used in ophthalmology for eye irrigation and in urology for bladder irrigation.

The material of spülkanülen varies, with stainless steel and plastic being common choices. Stainless steel cannulas are often reusable and can be sterilized, while plastic ones are typically single-use, offering convenience and reducing the risk of cross-contamination. The size and gauge of spülkanülen are chosen based on the specific application and anatomical location. Their blunt tip is a key safety feature, minimizing the risk of accidental perforation or injury to surrounding tissues.
