Summary. Scientific research is impossible without experiments on laboratory animals. At the same time, difficulties often arise in equipping such works with surgical instruments and technical devices. The aim of this study is creation and testing the surgical instruments for working with small laboratory animals. Surgical instruments were created and introduced into practice: a surgical hook, a retractor, a device for static fixation of tissues, and also a device for fixing animals. The developed instruments were tested in experiments on 160 laboratory rats for surgery on the spine and spinal cord. Usability, wear resistance, the ability to produce multiple copies were evaluated. These instruments have also been disinfected and sterilized with special equipment. The device for fixing animals was used during x-ray examinations. The use of the presented devices showed their ergonomics, resistance to processing cycles, as well as compliance with the requirements for medical instruments.

Keywords: experiment, laboratory rat, surgical instruments, microsurgery, ergonomics, surgical retractor, surgical dilator, device for fixation, radiography.
