Payr’s Pylorus Clamp

What is Payr’s Pylorus Clamp? The clamp is named after Erwin Payr who was Austrian-German surgeon. This is a lever-action clamp which is also known as Payr’s Intestinal Crushing Clamp because of its ability to crush the intestine. The clamp has four joints, the three joints in proximity are for the handles and they operate the distal joint. The jaws are attached to the fourth distal joint. When the handles are approximated they result in firm closure without the fear of the handles springing apart. The jaw may or may not have pins. The presence of pins enhances the gripping ability of the clamp.

What is its function? This clamp is used to occlude the lumen of the intestine to prevent spillage of gut content and to occlude the blood supply of the diseased part of the gut.

Surgical Procedures: The crushing clamp in opposition to the intestinal occlusion clamp is used to crush the diseased part of the gut in resection anastomosis as mentioned above. The resection anastomosis is a surgical procedure in which diseased part of the gut is cut out and the healthy parts are joined again.



The procedure is carried out in case of strangulated hernia (the gut trapped in this case of hernia becomes nonviable), diverticulitis (inflammation of diverticulum) or intestinal cancer.

There are other crushing clamps as well but this is by far the most popular one.

Age Group and Available Sizes: The clamp is available in variant sizes so that it can be used on adults and children both. The available sizes for the adults are 13 ¾ inches(349mm) and 8 inches(203mm) having jaw lengths of  3 inches(76mm) and 5 ¾ inches(146mm) respectively. Both the sizes are available with either pins or without pins. While the length of the clamp for pediatric age group is 5 ¾ inches (145mm) with jaw length of 2 3/16 inches (55m) with or without pins.
