ARTICULATING TISSUE DISSECTOR

摘要

A tissue dissector can include a tool body having a proximal end and a distal end. The tool body can include a longitudinal path therein between the proximal end and the distal end. The path can include an arcuate portion disposed adjacent the distal end and a horizontal portion extending proximally from the arcuate portion. A cutting blade can be pivotably attached to the body with via a first pin. A central shaft can be coupled to the first pin. A handle assembly can be coupled to the central shaft. A second pin can be fixed to the cutting blade, engage the path of the tool body and be located offset from the first pin to pivot the blade about the first pin as the blade moves in a proximal direction from a farthest distal extent of the path in the tool body.

主权项

1. A tissue dissector, comprising:
a tool body having a proximal end and a distal end, and defining a J-shaped path between the proximal and distal ends; a blade movably attached to the distal end of the tool body; and a handle coupled to the proximal end of the tool body, which actuates the blade such that the blade rotates up to 90 degrees out from a longitudinal axis of the tool body along the J-shaped path to create a J-shaped pathway in a patient's tissues.
