Summary of the Inventive Concept
An improved handheld electromechanical surgical system that enhances surgical accuracy, precision, and versatility, while reducing user fatigue and complications.
Background and Problem Solved
The original handheld electromechanical surgical system had limitations in terms of clamping force accuracy, motor speed calibration, reload design, ergonomic grip, and visualization. The new inventive concept addresses these limitations by integrating a force sensor, calibrating motor speed, featuring a modular reload design, incorporating an advanced ergonomic grip, and providing real-time visualization.
Detailed Description of the Inventive Concept
The enhanced handheld electromechanical surgical system comprises a handle assembly with an integrated force sensor to detect changes in tissue resistance during a surgical procedure, enabling real-time adjustment of clamping force and improving surgical accuracy. The system's motor speed is calibrated based on the type of tissue being operated on, optimizing surgical outcomes. The modular reload design features interchangeable cartridge modules, each configured for a specific type of surgical procedure, increasing the device's versatility and convenience. The advanced ergonomic grip design with adjustable ergonomic settings reduces user fatigue and improves overall surgical performance. The integrated visualization system, comprising a high-resolution camera and display, provides real-time visual feedback to the user during a surgical procedure, enhancing surgical precision and reducing complications.
Novelty and Inventive Step
The new inventive concept introduces a novel combination of features that improve the original handheld electromechanical surgical system. The integration of a force sensor, motor speed calibration, modular reload design, advanced ergonomic grip, and real-time visualization provides a non-obvious solution to the limitations of the original patent.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include varying the type and placement of the force sensor, using different motor speed calibration algorithms, or incorporating additional features such as tissue identification or automated reload detection. Variations could also include adapting the system for use in different surgical specialties or procedures.
Potential Commercial Applications and Market
The enhanced handheld electromechanical surgical system has significant commercial potential in the medical device industry, particularly in the fields of general surgery, laparoscopic surgery, and endoscopy. The system's improved accuracy, precision, and versatility make it an attractive solution for hospitals, clinics, and surgical centers.
