Abstract
A surgical instrument that allows a surgeon to temporarily halt the flow of blood to a tissue during a surgical procedure (temporary hemostasis) and restore the flow of blood to the tissue when desired without damaging the tissue is described. The instrument comprises a handle means, a hollow barrel member, a loop and an operating means coupled to the loop to drive the loop between contracted state and an expanded state. Preferably, one end of the loop is removable from the operating means so that temporary hemostasis can be induced in virtually any tissue of the body.
