This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,214.

Summary of the Inventive Concept

The Smart Tissue Manipulation System is an advanced medical instrument that integrates sensors, micro-actuators, and haptic feedback to enable precise, real-time tissue grasping and manipulation during minimally invasive procedures.

Background and Problem Solved

The original patent's multi-functional medical device has limitations in terms of tissue grasping force and manipulation precision. The new inventive concept addresses these limitations by incorporating advanced technologies to improve the safety and efficacy of minimally invasive procedures.

Detailed Description of the Inventive Concept

The Smart Tissue Manipulation System comprises a medical instrument with a member having a proximal end and a distal end, an end effector having a first arm and a second arm, and a sensor to detect tissue properties. The system further includes a control unit configured to receive input from the sensor and adjust the grasping force in real-time. Additionally, the system features a micro-actuator to enable precise grasping and manipulation of tissue, and a haptic feedback system to provide tactile feedback to the user based on the grasping force and tissue properties. The system enables surgeons to perform procedures with increased precision, safety, and efficiency.

Novelty and Inventive Step

The new inventive concept's integration of sensors, micro-actuators, and haptic feedback represents a significant improvement over the original patent, providing a more precise and controlled tissue manipulation experience. The real-time adjustment of grasping force based on tissue properties and the provision of tactile feedback to the user are novel and non-obvious features that distinguish the Smart Tissue Manipulation System from existing medical instruments.

Alternative Embodiments and Variations

Alternative embodiments of the Smart Tissue Manipulation System could include variations in sensor types, micro-actuator designs, and haptic feedback mechanisms. Additionally, the system could be adapted for use in different medical specialties, such as neurosurgery or orthopedic surgery.

Potential Commercial Applications and Market

The Smart Tissue Manipulation System has significant commercial potential in the medical device industry, particularly in the minimally invasive surgery market. The system's advanced features and improved performance could make it an attractive option for hospitals and medical centers, leading to increased market share and revenue growth.
