PI Mini Imaging Drives For Endoscopy

Source: PI (Physik Instrumente) LP

With the aim to cause patients as little discomfort as possible, minimal invasive surgery (MIS) techniques use endoscopes integrated with a miniature drive to achieve variable focusing so that objects can be in sharp focus at all times. These endoscopes are used in larynx diagnostics or laparoscopy where optics and special instruments can then be introduced to the abdominal cavity through working trocars. Patients will then experience less post-operative pain and are able to be discharged earlier from the hospital.
