Scissors system for surgical craniosynostosis treatment

摘要

A skull bone cutting scissors system is disclosed that comprises a scissors assembly including having first and second members each having a handle portion and a blade portion. The first and second members have an inner periphery and an outer periphery, with at least a section of the inner periphery of the blade portion being sharpened. The second member is pivotally connected to the first member. The first member has a conductive section located along a portion of the inner periphery and the second member has a conductive section located along a portion of the inner periphery. The system includes a cautery energizing apparatus in electrical communication with the conductive section of the first member and the conductive section of the second member. The cautery energizing apparatus is configured to provide power to the conductive sections of the first member and the second member.

1. A skull bone cutting scissors system comprising:
a scissors assembly comprising:
a first member having a proximal end and a distal end, the first member having a handle portion located toward the proximal end and a blade portion located toward the distal end, the first member having an inner periphery and an outer periphery, at least a section of the inner periphery of the blade portion forming a first cutting edge;a second member having a proximal end and a distal end, the second member having a handle portion located toward the proximal end and a blade portion located toward the distal end, the second member having an inner periphery and an outer periphery, at least a section of the inner periphery of the blade portion forming a second cutting edge;wherein the second member is pivotally connected to the first member to move the first cutting edge of the first member along the second cutting edge of the second member to shear bone material contacted by the converging cutting edges of the first and second members;wherein the first member has a conductive section located along a portion of the first cutting edge on the inner periphery of the first member;wherein the second member has a conductive section located along a portion of the second cutting edge of the inner periphery of the second member; and a cautery energizing apparatus in electrical communication with the conductive section on the first cutting edge of the first member and the conductive section on the second cutting edge of the second member, the cautery energizing apparatus being configured to provide power to the conductive sections of the first member and the second member; wherein each of the blade portions of the first and second members has a pair of opposite faces; a first flange located along at least a portion of the outer periphery of the first member and extending outwardly from at least one of the opposite faces of the blade portion, and a second flange located along at least a portion of the outer periphery of the second member and extending outwardly from at least one of the opposite faces of the blade portion; and wherein the conductive sections of the first and second cutting edges are entirely located in a space between the first and second flanges; wherein the handle portion of the first member has a longitudinal axis and the blade portion of the first member has a longitudinal axis, the longitudinal axis of the handle portion and the longitudinal axis of the blade portion forming a non-zero angle.
