Surgical staple

The use of staples over sutures reduces the local inflammatory response, width of the wound, and time it takes to close a defect.

The technology was refined in the 1950s in the Soviet Union, allowing for the first commercially produced re-usable stapling devices for creation of bowel and anastomeses.

[7][2] In patients that are subjected to pulmonary resections where lung tissue is sealed with staplers, there is often postoperative air leakage.

Circular staplers are used for end-to-end anastomosis[broken anchor] after bowel resection or, somewhat more controversially, in esophagogastric surgery.

Laparoscopic staplers are longer, thinner, and may be articulated to allow for access from a restricted number of trocar ports.

Apart from the different modality of coupling of vascular (everted) in respect to digestive (inverted) stumps, the main basic reason could be that, particularly for small vessels, the manuality and precision required just for positioning on vascular stumps and actioning any device cannot be significantly inferior to that required to carry out the standard hand suture, then making of little utility the use of any device.

This is finalized to make as brief as possible the donor organ dangerous warm ischemia phase that can be contained in the couple of minutes or less necessary just to connect the device's ends and actioning the stapler.

Titanium produces less reaction with the immune system and, being non-ferrous, does not interfere significantly with MRI scanners, although some imaging artifacts may result.
