Abstract
An improvement to a tissue removal device, that is, the addition of an adjustable protective guard and/or a retractable protective guard on the blade guard sheath of a mechanical tissue morcellator is presented. The retractable protective guard can be fixedly located at the distal end of a blade guard sheath and can be openly operated by a spring loaded means or a trigger means. The adjustable protective guard is moveably mounted in close contact around the blade sheath and may be positioned at any point along the length of the blade guard sheath in either direction. The addition of the adjustable protective guard and the retractable protective guard on the blade guard sheath of the mechanical tissue morcellator act to control and direct positioning of the tissue morcellator within the body cavity of the patient.
