三角緘
Also called the ashi sankaku garami (leg triangle entanglement) in [[judo]] and the coil lock in catch wrestling, the omoplata is a [[joint lock]] technique in Brazilian jiu-jitsu. It is preformed by using the attacker's legs and hips to extend an opponent's shoulder joint past its normal range of motion. The lock applied to the shoulder is similar to the [[Kimura lock]], but the legs are used in place of the figure-four grip.
