## 4 Conclusions  
We presented the design, fabrication, and multiple testing stages of a specialized platform that is aimed at compensating for the hand tremor in medical laser equipment. The key development aspects have included the design of a Stewart-type platform tailored for laser surgery, the design and integration of a mechanical amplifier within the macro-scale platform, the fabrication and visual inspection of the amplifier, the static FEA and experimental validation, as well as a dynamical FEA simulation of the amplifier. The results of this study have been promising; therefore, one may consider that they provide a solid foundation for further development, including miniaturization and optimization of the system. In this respect we must highlight that the proposed device serves as a proof-of-concept and has not been designed for immediate surgical applications. Future research and development efforts are focused both on miniaturization and on transitioning the device toward practical, real-world applications. A contribution of this work lies in the development of a novel mechanical amplifier model, which enhances the performance of the system by optimizing the force transmission within the compliant mechanism. Flexible wires have been utilized, thus simplifying the assembly process and introducing a pseudo-spherical joint. Additionally, a key innovation lies in the introduction of a hybrid experimental testing approach that combines a high-resolution optical 3D measurement system with a material testing machine. This dual-method approach enables precise validation of the 3D amplifier model, material behavior, and static performance of the compliant mechanism, while also providing preliminary insights into its dynamic behavior and useful frequency range. To advance toward practical implementation, ongoing and future work on this proof-of-concept prototype includes: (i) a flexural analysis of the entire amplifier body under the applied actuator forces (including the elastic joint); (ii) the calculus of the stiffness and compliance for the amplifier; (iii) development of a flexural/mechanical model of the entire elastic structure, including an evaluation of stiffness, compliance, and natural frequencies; (iv) dynamic experiments to assess the mechanical amplifier, actuating subsystem, and overall system response; and (v) the ascertainment of the vibration compensation capabilities in its intended function as a laser scalpel.

Overall, one may say that the results of this study demonstrate the feasibility of the proposed design and its potential for future applications, in particular in medical robotics and precision surgical tools.
