Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current minimally invasive surgical procedures for intra-abdominal surgery lack efficient methods for insufflation that minimize tissue trauma and ensure precise perforation without damaging adjacent organs.
Innovation Solution
A method and device involving a hollow needle inserted into a hollow internal organ, using a wireless scanning apparatus to detect the absence of tissues before perforation, and conveying pressurized carbon dioxide gas through the needle, with an optional port element for maintaining access and minimizing tissue damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a needle is inserted through the abdominal wall for insufflation, then the abdominal cavity can be insufflated, but there is a risk of damaging adjacent organs
Solution Approach 1:
The wireless scanning apparatus performs preliminary detection of adjacent organs before the needle insertion procedure. The system maps the location of internal organs and identifies safe zones for needle passage, allowing the surgeon to plan the insertion path in advance to avoid vital structures.
Solution Approach 2:
The wireless scanning apparatus provides real-time or near-real-time feedback during the needle insertion process. The system continuously monitors the needle position relative to detected organs and alerts the operator if the needle approaches dangerous zones, enabling dynamic adjustment of the insertion path.
2Productivity
If traditional insufflation methods are used, then the abdominal cavity can be insufflated, but tissue trauma is increased
Solution Approach 1:
The patent replaces traditional mechanical blind insertion methods with a wireless scanning and imaging system. Instead of relying on anatomical knowledge and physical palpation alone, the system uses electromagnetic or acoustic fields to visualize internal structures, substituting mechanical trial-and-error with field-based detection and guidance.
3Measurement precision
If visual feedback is obtained via endoscope or radiographic equipment, then needle position can be monitored, but device complexity increases
Solution Approach 1:
The wireless scanning apparatus is designed to serve multiple functions: it detects organ locations, guides needle insertion, monitors needle position, and provides real-time feedback. This single multi-functional device replaces the need for separate endoscopes, radiographic equipment, and other monitoring devices, reducing overall system complexity while maintaining measurement precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces tissue trauma, minimizes the risk of damaging adjacent organs, and allows for efficient insufflation of the abdominal cavity, facilitating shorter hospital stays and less invasive surgical procedures.
Implementation Method 1
operating a wireless scanning apparatus externally of the patient to obtain data as to internal structures of the patient
Implementation Method 2
a pressurized fluid is conveyed through the needle into the patient on the side of the wall opposite the body cavity. The pressurized fluid is typically carbon dioxide gas.

AI summary
In a surgical method, a hollow needle is inserted into a hollow internal organ of a patient through a natural body opening. A wireless scanning apparatus is operated externally of the patient to obtain data as to internal structures of the patient on a side of a wall of the organ opposite the body cavity. A distal tip or free end of the needle is passed through the wall of the organ only upon detecting, via the wireless scanning apparatus, an absence of internal organic tissues of the patient in contact with the wall of the organ on the side of the organ opposite the body cavity. Upon the passing of the distal tip or free end of the needle through the wall of the organ, pressurized CO2 gas is conveyed through the needle into the patient on the side of the wall opposite the body cavity. The needle may be connected to the distal end of an elongate flexible hollow shaft and an endoscope may be optionally used to view the needle deployment procedure.
