A Conical Washer- Couple is a specialized component used in some external fixator systems. It consists of two conical washers that are designed to work together. When tightened, these washers create a strong and secure connection between different parts of the external fixator, such as the frame and the bone clamps. This helps maintain the stability and effectiveness of the washer. The conical shape of the washers helps to distribute pressure evenly and prevent the loosening of the components, which is crucial for successful bone healing.
