Surgical retractor for puncture operation

摘要

A surgical retractor is for use when extended through a trocar sleeve. The retractor has a pair of telescoping tubes. The inner one of the retractor tubes has a number of fingers which may be spread into a fan shape, and then articulated to select a position between 180 DEG and 90 DEG relative to the length of the tubes. For insertion and retraction into and out of the trocar sleeve, the fingers may be pulled into a compact configuration.
