VIBRATING SURGICAL INSTRUMENTS FOR BLUNT DISSECTION

摘要

A dissector including a body, a first arm, a second arm, and a string. The first arm extending from the body towards a distal end thereof and the second arm extending from the body towards a distal end thereof. One end of the string is coupled to the first arm adjacent the distal end thereof and the other end of the string is coupled to the second arm adjacent the distal end thereof. The first and second arms have an expanded configuration such that the string is taut and have a collapsed configuration such that the string is slack. The string is configured to dissect tissue when the first and second arms are in the expanded configuration. The string may oscillate to dissect tissue. The distal ends of the first and second arms may atraumatically dissect tissue.

1. A dissector comprising:
a body; a first arm extending from the body to a first distal end thereof; a second arm extending from the body to a second distal end thereof; and a string with one end coupled to the first arm adjacent the first distal end and the other end coupled to the second arm adjacent the second distal end, the string being taut when the first and second arms are in an expanded configuration and the string being slack when the first and second arms are in a collapsed configuration, the string configured to dissect tissue when the first and second arms are in the expanded configuration.
