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. 11,857,174.

Summary of the Inventive Concept

An advanced tissue manipulation device incorporating an integrated sensor, enabling real-time detection of tissue properties and optimized tissue manipulation through dynamic adjustment of the adjustment member and securing member.

Background and Problem Solved

The original tissue manipulation device had limitations in terms of accuracy and efficiency. The new inventive concept addresses these limitations by integrating a sensor to detect tissue properties, enabling real-time feedback and adjustment of the device for optimal tissue manipulation.

Detailed Description of the Inventive Concept

The enhanced tissue manipulation device comprises a handle portion with an integrated sensor for detecting tissue properties, an adjustment member displaceably coupled to the proximal end of the handle portion, and a securing member coupled to the handle portion, extending along a member axis and being pivotably displaceable from between an engaged position and a disengaged position. The integrated sensor provides real-time data on tissue properties, which is transmitted to a control unit that adjusts the adjustment member accordingly. This enables the device to dynamically adapt to changing tissue conditions, ensuring optimal tissue manipulation. The securing member is biased into engagement with the distal portion of the adjustment member by a resilient member with a variable stiffness, allowing for further fine-tuning of the device's operation.

Novelty and Inventive Step

The new claims introduce the concept of integrated sensing and real-time feedback, which enables the device to adapt to changing tissue conditions and optimize tissue manipulation. This is a significant departure from the original patent, which relied on manual adjustment and lacked real-time feedback.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of sensors, such as optical or electrical impedance tomography, or the integration of additional features, such as visualization modules or haptic feedback. Variations of the device could be designed for specific medical procedures or applications, such as laparoscopic or robotic-assisted surgery.

Potential Commercial Applications and Market

The enhanced tissue manipulation device has significant commercial potential in the medical device industry, particularly in the areas of laparoscopic and robotic-assisted surgery. The device's ability to provide real-time feedback and adapt to changing tissue conditions makes it an attractive solution for surgeons and medical professionals seeking to improve patient outcomes and reduce complications.
