Abstract
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.degree. and 90.degree. 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.
Claims10
A retractor for use during surgical procedures conducted through trocar sleeves, said retractor comprising telescoping inner and outer retractor tubes, a plurality of fingers pivotally attached to a distal end of one of said tubes, and means on a proximal end of said tubes for selectively controlling the pivotal attitude of said fingers, a block which is pivotally attached to said distal end of said inner tube, said fingers being attached to said block, a pull wire pivotally attached to said block in order to control the attitude thereof, said pull wire extending throughout the length of said inner retractor tube, and means at the proximal end of said inner tube for pulling or pushing said pull wire.
An elongated retractor for use during surgical procedures performed through a trocar sleeve, said elongated retractor having a plurality of fingers extending from a distal end of said retractor, said fingers spreading apart when extended from said distal end, means for pivotally enabling said extended and spread apart fingers to articulate over an approximate range of 180.degree. to 90.degree. relative to the elongated direction of said retractor, a pivot point for said articulation being located at the distal end of said retractor, means responsive to a control function performed at a proximal end of said retractor for articulating said extended and spread apart fingers, and means extending along a length of said retractor for articulating said fingers responsive to said control function performed at said proximal end.
An elongated device for controlling the position of human tissue during surgery, said device comprising means for selectively spreading a retracting means into a fan shape, means for articulating said fan shape to a selected position between an approximation of an extension of said elongation and a right angle relative to said elongation, means for locking said retracing means in said selected position, and means for compressing said fan shape into a compact configuration for movement into and out of an operative position.
