Abstract
A connector assembly is disclosed for connecting the proximal end of a medical device to a handle without compromising the sterility of the working (distal) end of the medical device. The connector assembly comprises a body that is rigidly attached to the proximal end of the medical device. A lever is attached to body and is resiliently biased towards a first position which engages the handle. A lock-tab projects from the lever in a direction generally away from the body and is shaped to be received in a lock-slot within the handle. The lock-tab and handle preferably are shaped to permit a snap-lock engagement of the handle and the body upon insertion of the body within the handle. This assembly can be used on a variety of medical devices and with a variety of handles. One industrial application is a biopsy needle having the connector assembly attached at its proximal end for a secure, snap-lock engagement to the handle.
