Endoscopic Stoma Closure via Pneumatic Arrow Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical methods for suturing small pits in hollow organs require invasive procedures like abdominal incisions and are complex, posing challenges in operability, safety, and suitability for patients with unusual conditions due to the need for delicate manual operations and potential damage to internal structures.
Innovation Solution
A surgical system using an endoscope or capsule endoscope with a suturing device that includes arrowy-shaped members and a suture thread, where compressed air or high-pressure gas is used to eject the members into tissue on both sides of the small pit, allowing for secure suturing without the need for major surgical procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surgical methods are used to suture small pits in hollow organs, then secure suturing can be achieved, but the procedure requires invasive abdominal incisions and complex manual operations
Solution Approach 1:
The patent replaces complex manual mechanical suturing operations with an automated endoscopic device that uses compressed air to eject arrowy-shaped members and automatically sutures the tissue, eliminating the need for delicate manual operations while maintaining suturing reliability
Solution Approach 2:
The patent uses compressed air to eject the arrowy-shaped members from the device and drive them into the tissue, providing a simple and effective mechanism for tissue engagement without requiring complex mechanical actuators or manual manipulation
2Reliability
If conventional surgical methods are used, then suturing can be performed, but the invasiveness and duration of surgery increase
Solution Approach 1:
The patent divides the surgical procedure into separate functional components: the endoscope provides visualization, the surgical device performs suturing, and compressed air provides actuation. This segmentation allows each component to be optimized independently, reducing overall invasiveness while maintaining suturing capability
Solution Approach 2:
The patent introduces compressed air as an intermediary to transfer energy from the gas shooter to the arrowy-shaped members, enabling tissue engagement without direct mechanical contact or invasive incisions, thereby reducing surgical invasiveness
3Reliability
If conventional surgical methods are used, then tissue can be sutured, but the risk of damage to internal structures increases
Solution Approach 1:
The patent applies the suturing action locally at the small pit site using the arrowy-shaped members that engage only the tissue immediately surrounding the defect, rather than requiring widespread dissection or manipulation that could damage internal structures
Solution Approach 2:
The arrowy-shaped members are pre-loaded into the device and positioned for immediate ejection upon contact with tissue, allowing the suturing action to be performed in a single controlled motion that minimizes the risk of accidental damage to surrounding internal structures
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
The system reduces the invasiveness and duration of surgery, improves operability and safety, and is suitable for patients with unusual conditions by eliminating the need for abdominal incisions and minimizing damage to internal structures.
Implementation Method 1
compressed air or high-pressure gas sequentially ejected into the suture-member cartridge (5) are ejected from the cartridge in sequence and driven into tissue in the hollow organ on both sides of the small-pit site
Implementation Method 2
a gas shooter (4) that includes a cylinder unit having (a) a piston that, through its operation, generates compressed air, and (b) a high-pressure-gas reservoir that stores high-pressure gas

AI summary
A surgical system for small-pit closure in hollow organs is provided. The surgical system is provided with a surgical device for small-pit closure in hollow organs, with the surgical device including the following components: a suture-member cartridge in which a pair of parallel tubular members that accommodate respective suture members are feedably connected to the rear ends of a pair of arrow-shaped members that latch into tissue in a hollow organ; an auxiliary shooting unit having plungers respectively provided in a pair of cylinders open at both ends; a hollow-organ-insertable unit configured of a pair of flexible air tubes; and a gas shooter that sequentially discharges compressed air or high-pressure gas into the open-ended cylinders in response to operations of a trigger, for sequentially ejecting the arrow-shaped members and driving the same into tissue in the hollow organ on both sides of a small pit site.
