BAYONET CONNECTOR FOR SURGICAL HANDPIECE

摘要

A connection of first and second members (11 and 12) wherein each has a body and a connecting end with an inner surface (17) so the second connecting end (19) has an outer surface (20) shaped for telescoping into the inner surface (17) of the first connecting end (16). A shoulder (21) is located on the second member (12) and a groove (22) is in the outer surface (20) of the second connecting end (19). A raised nub (23) on the inner surface (17) of the first connecting end (16) is radially inward to engage the groove (22). An elastomeric gasket (13) is positioned to bear against the shoulder (21) and be compressed between the first and second bodies. An engaging trough (24) in the groove (22) holds the first connecting end (16) against the shoulder (21) with the nub against the groove (22) by the compression force of the gasket (13). An indexing trough (25) in the groove (22) positioned along the groove (22) beyond the engaging trough (24) allows the nub to follow therethrough and slightly compress the gasket (13) thus giving the user a tactile indication that it has been rotated beyond the engaging trough (24). A method for fluid tight attachment of members (11 and 12) of a medical device has steps including the connection of the first and second members (11 and 12) with ends by telescoping the ends. Locating a groove (22) for operating the groove (22) as a cam (14) and locating a raised nub (23) of material on the inner surface (17) of the first connecting end (16) for positioning the raised nub (23) to engage the groove (22) for operating the raised nub (23) as a follower of the cam (14) are steps. Compressing a gasket (13) seal between the first connecting end (16) and the shoulder (21) while making the gasket (13) seal from an elastomeric material is a step. Positioning an engaging trough (24) in the groove (22) to hold the first and second connecting ends (19) against each other is a step. Positioning an indexing trough (25) in the groove (22) so when the nub is rotatably forced past the engaging trough (24) it will further compress the first end against the gasket (13) is a step.
