What cutting instrument is recommended for circumcision due to less trauma to end vessels?

A bipolar diathermy device is recommended for circumcision because it provides hemostasis while simultaneously cutting tissue. This method minimizes trauma to blood vessels compared to traditional cutting instruments. The bipolar diathermy works by passing an electrical current between two prongs, which cauterizes the vessels as it cuts, significantly reducing the risk of bleeding and providing better control over the surgical site. This feature is particularly valuable in delicate areas where precision is crucial, leading to a reduced incidence of complications related to bleeding.

On the other hand, while scalpels, electrocautery, and lasers are useful in various surgical scenarios, they have drawbacks in the context of circumcision. A scalpel can cause more trauma to surrounding tissues, potentially leading to greater postoperative bleeding. Electrocautery, although effective at controlling bleeding, can result in thermal injury to adjacent tissues, which may complicate recovery. Laser instruments, while precise, can also cause thermal damage and may not be as effective in controlling bleeding during circumcision as bipolar diathermy.
