[Separation of undamaged single nerve fibers by using an ultrasonic microscalpel].
A routine procedure for dissection of single nerve fibres with sharpened sewing needles is rather tiresome and occasionally traumatic because of poor efficiency in cutting interfibrous connective tissue and sticking out patches of it to preparative needles. The described method using microscalpel oscillating with ultrasonic frequency is free from these shortcomings. Voltage clamp tests proved an innocuous character of this method for excitable nodal membrane.
