  • Patent number: 8647348
    Abstract: A circumcision clamp for aiding the removal of the foreskin of an adult, human, male penis. A top clamp and a bottom clamp for circumcision each has: 1) a curved interior brace, placed between the foreskin and the penis shaft; and 2) a curved exterior brace, which aligns over the interior brace and compresses the foreskin against the interior brace. The curved interior brace preferably has a greater depth than the exterior brace, which greater depth forms a distal overhang or shelf for protecting the penis shaft during operation. By simultaneously employing a top clamp and a bottom clamp during circumcision, an entire band or collar of foreskin along the desired path of incision and suturing can be securely held in place and clamped, thus helping the operator or surgeon trim and suture the foreskin quickly and precisely.
