Summary of the Inventive Concept

An improved optical shape sensing device with integrated force sensing region and tip integration, providing real-time feedback on axial force exerted on the distal end of the elongated outer body, thereby enhancing shape sensing accuracy and quality.

Background and Problem Solved

The original patent, 'Optical shape sensing device with integrated force sensing region and tip integration', has limitations in providing accurate shape sensing data due to signal losses at the distal tip of the multicore optical fiber. The new inventive concept addresses this issue by integrating a force sensing region that provides real-time feedback on axial force, enabling more accurate shape sensing and compensation for signal losses.

Detailed Description of the Inventive Concept

The enhanced optical shape sensing device comprises a multicore optical fiber extending through an elongated outer body, a force sensing region integrated with the elongated outer body, and a signal processing unit that amplifies and filters signals from the force sensing region to reduce noise and interference. The force sensing region is designed to provide real-time feedback on axial force exerted on the distal end of the elongated outer body, allowing for calibration and compensation of signal losses at the distal tip of the multicore optical fiber. The signal processing unit ensures accurate and reliable shape sensing data, enabling improved performance in medical procedures and other applications.

Novelty and Inventive Step

The new claims introduce the concept of integrating a force sensing region with the elongated outer body, providing real-time feedback on axial force and enabling calibration and compensation for signal losses. This novel approach enhances shape sensing accuracy and quality, making it a non-obvious improvement over the original patent.

Alternative Embodiments and Variations

Alternative embodiments may include varying the design of the force sensing region, using different materials or structures for the elongated outer body, or integrating additional sensors or components to further enhance shape sensing accuracy. Variations may also include adapting the device for use in different medical procedures or applications.

Potential Commercial Applications and Market

The enhanced optical shape sensing device has significant commercial potential in the medical device industry, particularly in minimally invasive procedures where accurate shape sensing is critical. The device may also find applications in other industries, such as robotics, aerospace, or industrial automation, where precise shape sensing and force feedback are essential.
