摘要：
A needle for collecting a tissue samples includes a needle body extending along a longitudinal axis from a proximal end to a distal end including a sharp tip for penetrating a target tissue. The needle body includes a channel extending therethrough for collecting a tissue sample therein when the distal end is inserted into the target tissue. A distal portion of the needle body has a first stiffness and a proximal portion of the body has a second stiffness of the proximal portion less than the first stiffness. The needle also includes a sleeve extending along a length of the needle body to cover the pattern along the proximal portion.
