This invention is directed to hemostasis in the lips and the mucosal side of the cheek. These devices are not used for stopping each vessel from bleeding but are used for temporarily stopping the total blood supply to the entire surgical area. Model A has a pair of lip-shaped jaws for providing hemostasis in the entire upper or lower lip. The jaws are curved to conform to the entire lip and formed to interlock to permit longitudinal movement in jaw menbers. This structure is used for changing the size of jaws to adapt to different sizes of lips. Model A has two pairs of arms for maintaining a constant hemostatic pressure throughout the entire lip. Another design is constructed to provide hemostasis in a small area on the lip. Its jaws are semicircular and curved 90 DEG with semicircular parts of arms so that the surgeon can have access to surgical field easily without obstruction. Another model is designed to obtain hemostasis in the mucosal side of the cheek. Its circular jaws are combined with a pair of 90 DEG angulated arms. In the second and third models, the jaw-arm 90 DEG angulation is combined with an interlocked longitudinally movable system for keeping a constant parallel between the jaws in order to obtain hemostasis most effectively. A locking bolt-like bar has two threads. The distal thread is used for keeping the nut on the bar when releasing the device. The proximal thread is used for desirably adjusting the hemostatic pressure.
