Hexagonal Handle Surface for Surgical Instrument Grip

The patent replaces sharp pyramid-shaped grooves with rounded, dome-shaped enclosures having curved surfaces. This curvature eliminates sharp edges that cut gloves while maintaining the mechanical interlocking effect for grip security. The rounded geometry allows force distribution without concentration at specific points, preventing glove damage.

The patent changes the geometric parameters of the surface structures from sharp angular pyramids to rounded domes with specific radius ratios. The enclosure radius to opening radius ratio is optimized to provide sufficient grip while ensuring rounded transitions that prevent glove cutting. This parameter optimization resolves the contradiction between grip effectiveness and glove protection.

The rounded dome-shaped enclosures with curved surfaces prevent liquid accumulation by eliminating sharp corners and flat bottoms where liquid would pool. The curved geometry facilitates liquid runoff during cleaning and sterilization processes, making the handle easier to clean while maintaining grip effectiveness through the same rounded structures.

The patent optimizes the depth, width, and curvature radius of the enclosures to achieve a balance between grip provision and liquid drainage. The specific radius ratios ensure that the enclosures are deep enough to provide mechanical interlocking for grip but have curved profiles that prevent liquid pooling, thereby improving cleaning efficiency.

The patent uses an asymmetric hexagonal arrangement of rounded enclosures that provides optimized grip in the primary thumb application direction while maintaining adequate grip in other orientations. The hexagonal symmetry with six-fold arrangement creates direction-dependent optimization without complete directionality, balancing grip security with handling versatility for different surgical instruments.

The hexagonal enclosure arrangement serves multiple functions: it provides optimized grip for thumb application, maintains adequate grip for other finger configurations, and offers consistent performance across different instrument orientations. This multi-functional design resolves the contradiction between direction-specific optimization and general adaptability.

The patent segments the smooth handle surface into multiple discrete rounded enclosures distributed across the handle surface. This segmentation provides grip-enhancing features without creating continuous complex structures, maintaining manufacturing simplicity while improving grip security through distributed mechanical interlocking points.

The patent introduces controlled surface geometry changes with specific radius ratios and enclosure dimensions that optimize grip while maintaining manufacturability. The parameters are chosen to balance the complexity of surface structure with the need for effective grip, resolving the contradiction between smooth simple surfaces and grip-enhancing features.
