Abstract:
1. A modular scalpel assembly, comprising: a handle assembly and at least one blade assembly connectable thereto and separable therefrom, each at least one blade assembly including a blade affixed thereto at a distal end, wherein the scalpel assembly includes a plurality of blade assemblies that are interchangeable with the handle assembly, wherein the handle assembly with the blade assembly connected thereto is adapted to provide for retraction of the blade into the distal end of the blade assembly and wherein the handle assembly includes a handle casing and a handle rod disposed therewithin and movable therewithin, with the handle assembly having an arrangement that defines a distal-most position for the handle rod and a proximal-most position therefore, wherein a distal end of the handle rod is engageable with a proximal end of a retractable rod within the blade assembly to move the retractable rod to a distal-most position extending the blade thereof for surgical use, when the handle rod is in its distal-most position, and wherein a spring within the blade assembly is under compression when the handle rod is in its distal-most position, wherein the arrangement comprises a slot in the handle casing cooperable with a radially extending pin of the handle rod to permit the pin to travel along the slot, whereby the handle rod moves controllably within the handle casing between the distal-most and proximal-most positions.
