Summary
This study introduces rubber-coated metal springs for intermediate stereotactic frame fixation, improving patient comfort and stability during neurosurgery. The innovative device ensures precise head-to-frame alignment, enhancing the Leksell stereotactic system.
Area of Science:
- Neurosurgery
- Medical Device Development
- Biomedical Engineering
Background:
- Stereotactic surgery requires precise patient fixation.
- Current methods may cause discomfort or instability.
- A need exists for improved intermediate fixation techniques.
Purpose of the Study:
- To develop a novel device for painless, intermediate fixation of stereotactic frames.
- To enhance patient comfort and system stability during stereotactic procedures.
- To evaluate the efficacy of rubber-coated metal springs as an accessory for the Leksell stereotactic system.
Main Methods:
- Development and optimal shape determination of rubber-coated metal springs using 30 volunteers.
- Clinical testing of the springs on 15 patients undergoing stereotactic surgery.
- Measurement of frame stability and patient convenience, including head-to-frame distances.
Main Results:
- The optimal shape of the metal springs was determined through volunteer testing.
- Clinical evaluation in 15 patients demonstrated good tolerance and patient convenience.
- Measurements confirmed symmetric distances between the patient's head and the stereotactic frame, indicating stability.
Conclusions:
- Rubber-coated metal springs provide a useful accessory for the Leksell stereotactic system.
- The developed device allows for intermediate, painless fixation prior to definite pin fixation.
- This innovation enhances stability and patient comfort in stereotactic neurosurgery.
