摘要:
A surgical micro-burring instrument including an outer tubular member coaxially maintaining an inner tubular member. The outer tubular member defines a proximal section, a distal section, and a central lumen extending from the proximal section to the distal section. The distal section forms a pocket and an elevator tip. The pocket has a bottom wall and an opposed upper opening. The elevator tip extends distal the pocket. The inner tubular member forms a bur received within the pocket. Upon final assembly, at least a portion of the bur is exposed relative to the outer tubular member via the upper opening of the pocket. The elevator tip is configured to facilitate lifting of soft tissue, such as mucosa, while positioning the bur, via the pocket, in an appropriate location for cutting contacted harder tissue, such as turbinate bone or septal bone/cartilage.
