Sagittal Blade Cartridge Guide Bar Reinforcement Against Flexure

The guide bar is divided into three separate plates (top plate, bottom plate, and inner plate) that are positioned alongside each other rather than being a single thick structure. This segmentation allows the guide bar to achieve sufficient rigidity through the combined structural support of multiple thinner plates while maintaining the ability to produce smooth cut surfaces, as each plate remains thin enough to allow flexible blade movement and precise cutting action.

The guide bar is constructed as a composite structure using three distinct plates made of suitable materials that work together to provide the required mechanical properties. This composite approach allows optimization of each plate's thickness and material characteristics to achieve both rigidity for resisting flexure and sufficient flexibility for maintaining cut smoothness, resolving the contradiction between these two requirements.

The guide bar is segmented into three plates that can work independently to some extent, allowing the structure to maintain its static position for ease of operation while the distributed plate structure provides enhanced resistance to deformation from uneven bone resistance. The segmentation allows force distribution across multiple elements rather than concentrating stress in a single thick bar.

The structural parameters of the guide bar are changed by using multiple thinner plates instead of a single thick bar. This parameter change allows the guide bar to maintain static positioning for operational stability while the multi-plate configuration provides increased resistance to deformation through distributed structural support and force distribution across the three plates.
