Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current minimally invasive surgeries face challenges in precisely locating tumors, determining incision points, angles, and depths, and implementing resection paths due to the limitations of ultrasonic apparatuses, which result in inaccurate tumor resection and potential damage to surrounding structures.
Innovation Solution
A laser-assisted tumor localization and resection device comprising a laser displacement sensor, cylindrical base, joint part, transmission rod, and data screen, which uses a trigonometric model to guide surgeons in real-time by displaying beam ranging and included angles, allowing for precise localization of a triangular model containing the tumor, ensuring correct surgical planes and adequate resection margins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultrasonic apparatus is used for tumor localization, then the projection points of tumors can be identified on the surfaces of the organs, but the accuracy of further ultrasonic examination is decreased due to gas filling after incising
Solution Approach 1:
The patent replaces the ultrasonic apparatus with a laser displacement sensor system that uses laser beams to measure distances and calculate tumor positions. The laser-based optical measurement system avoids the limitations of ultrasonic waves being blocked by gas, providing continuous accurate measurement throughout the surgical process.
Solution Approach 2:
The patent changes the measurement parameter from ultrasonic wave reflection to laser displacement measurement. By using laser beams to measure the distance from the sensor to the tumor surface and combining this with angle information, the system calculates real-time tumor position without being affected by gas filling in the surgical field.
2Ease of operation
If traditional surgical methods are used, then surgeons can perform resection, but the location and depth of tumors cannot be determined by the naked eye and touch
Solution Approach 1:
The patent implements a real-time feedback system where the laser displacement sensor continuously measures the distance to the tumor surface, and the data processing unit calculates and displays the tumor's real-time position and depth. This provides surgeons with continuous feedback during the resection process, enabling precise control of the surgical knife along the planned path.
Solution Approach 2:
The patent introduces a data processing unit and display interface as intermediaries between the laser measurement system and the surgeon. The system processes raw laser displacement data and angle information to calculate tumor position, then presents this information in a user-friendly format that guides the surgeon's actions without requiring direct interpretation of complex measurements.
3Device complexity
If no real-time navigation system is used, then surgical equipment is simpler, but there is no method to precisely guide surgeons in real time to dissect the organ parenchyma by the resection path planned preoperatively
Solution Approach 1:
The patent designs a compact integrated device where the laser displacement sensor, angle sensor, data processing unit, and display interface work together as a single system. The laser sensor serves multiple functions by measuring both distance and angle information, which are then processed to provide comprehensive real-time guidance for the entire resection process, making the system accessible for various surgical applications.
