Cooper Stereotactic Device

This device was designed by Dr. Irving Cooper to provide the stereotactic direction of his cryoprobe in stereotactic thalamotomy in patients with movement disorders.

Professor Lauri Laitinen, one of the pioneers of modern movement disorder neurosurgery, started operating on Parkinson patients in Helsinki in 1963, using the Cooper Stereotactic Device. Later, he invented his own frame, which was in use for 20 years in many places in the Nordic countries ¹⁾.
