Cooley – Instruments for cardiovascular surgery

The typical feature of the atraumatic surgical instruments is the design of the jaw. The unique serration and arrangement of the teeth makes the jaw of Cooley instruments so special. The single or double serration allows the tissue or organs to be injured as little as possible during surgery. There are different variations of jaw surfaces:

Instruments Made in Germany - How did the August Reuchlen company come to Cooley?

The cooperation with William Merz, former instrument maker and later Vice President of V. Mueller in Chicago, and August Reuchlen began far before the introduction of the Cooley clamps in the late 1960s. After Merz chose the August Reuchlen company in Tuttlingen for the complex production of the Debakey, Mueller-Markham and Glassman serrations, which are also atraumatic, Reuchlen also became involved in the manufacturing of the Cooley clamps. In order to produce the fine toothing, it was necessary to purchase new machines. At this time, the August Reuchlen company was the only company that produced Cooley for V. Mueller.
Interesting side note: Before the surgical devices manufactured so far, known by the V. Mueller catalog, went into circulation, Dr. Cooley himself tested the instruments on his own operating table. This process, in consultation with William Merz and August Reuchlen, resulted in frequent re-adjustment and fine-tuning of the serrations.
