A Gomco clamp, otherwise known as a Yellen clamp, is a specialized clamp for performing circumcisions. It was invented by Hiram S. Yellen and Aaron Goldstein in 1934-1935. Gomco stands for the ''GOldstein Medical COmpany'', the original manufacturer of the clamp.〔 In a 1998 study, it was the preferred circumcision technique of 67% of US physicians. ==Method== The technique is as follows: # Anesthetic should be applied (though it is an historically recent addition, dating only to approximately the early 1990s). # The foreskin is gripped with two hemostats (tissue holders) and a probe is inserted between the foreskin and glans to break any adhesion.〔 # Once separated, a hemostat is used to crush the foreskin lengthwise in order to reduce bleeding.〔 HealthWise Medical Reference, Available online at: http://children.webmd.com/tc/circumcision-what-happens-during-a-circumcision Last Updated: February 19, 2008.〕 # Next, the foreskin is cut lengthwise where it was crushed to allow space to insert the clamp.〔 # The bell of the clamp is placed over the glans, and the foreskin is pulled over the bell. # The base of the clamp is placed over the bell, and the clamp's arm is fitted. # After the surgeon confirms correct fitting and placement, and the amount of foreskin to be excised, the nut on the Gomco clamp is tightened, causing the clamping of nerves and blood flow to the foreskin. # The clamp is left in place for about five minutes to allow clotting to occur, then the foreskin is severed using a scalpel. # The clamp's base and bell are then removed from the penis. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gomco clamp」の詳細全文を読む スポンサード リンク
