Microsurgical handle and instrument

An instrument comprising:

• an actuation structure having an actuation structure distal end and an actuation structure proximal end;
• a plurality of actuation arms of the actuation structure, each actuation arm of the plurality of actuation arms having an extension joint;
• an inner bore of the actuation structure;
• a nosecone fixed to the actuation structure;
• a distal barb fitting of the nosecone;
• a handle base housing of the actuation structure;
• a handle base having a handle base distal end and a handle base proximal end, the handle base distal end disposed within the handle base housing wherein the handle base is fixed to the actuation structure;
• an end plug fixed to the handle base;
• a proximal barb fitting of the end plug;
• and
• a tube having a tube distal end and a tube proximal end, the tube disposed in the inner bore of the actuation structure and in the handle base wherein the tube proximal end is disposed over the proximal barb fitting forming a first hermetic seal and wherein the tube distal end is disposed over the distal barb fitting forming a second hermetic seal.
