  • Publication number: 20050192592
    Abstract: A self-tensioning handle for use with endoscopic devices is disclosed. The handle may have mounting features for mounting a sheath and a control rod from an endoscopic device, such as a grasper or a retrieval basket. One mounting feature, such as a pin vise to hold a sheath, may be mounted in a distal portion of the handle, nearer a patient. Another mounting feature for a control rod or cannula of the endoscopic device is preferably mounted in a proximal portion of the handle. The handle is assembled with a tension or a pre-load so that a surgeon is not required to continually grip and compress the handle to retain a sample in the retrieval basket or other end-effector used with the handle.
