Abstract: A curved-head hemorrhoid banding device may include an inner cylinder curved at one end for sucking the hemorrhoid tissue into the device for banding. The device also may include a curved outer cylinder for releasing a rubber band, a straight barrel for pushing the curved outer cylinder to release the rubber band, an airtight plunger (or operator handle), and a handle for generating negative pressure. The banding device may provide tighter contact with hemorrhoid tissues and thus may provide better suction of hemorrhoid feeding vessels and adjacent rectal mucosal tissue. When being manipulated into contact with the internal hemorrhoid feeding vessel position, the device may maximally fit the anatomic configuration of the rectum, causing less discomfort to the patient during banding and after the procedure. The banding device may be disposable and designed for single-handed use.
