摘要：
Methods and devices for performing percutaneous surgery in a patient are provided. A retractor includes a working channel formed by a first portion coupled to a second portion. The first and second portions are moveable relative to one another from an unexpanded onfiguration to an expanded configuration to increase the size of the working channel along the length of the working channel while minimising trauma to skin and tissue.
