Robotic Gastrectomy System with Adherent Marking for Precise Stomach Transection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During bariatric surgical procedures, clinicians face challenges in accurately transecting the stomach along a straight line due to limited maneuverability and steadiness of surgical instruments, which can lead to inadvertent damage to stomach or esophageal tissue.
Innovation Solution
A robotic surgical system is employed to perform bariatric surgery by positioning a gastrectomy device, applying an adherent material along a desired transection line, and using a robotically-controlled surgical instrument to cut the stomach, with optional activation of the adherent material for enhanced visibility and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a robotic surgical system is used to perform stomach transection, then manufacturing precision and reliability are improved, but device complexity increases
Solution Approach 1:
The robotic surgical system is divided into multiple independent components: a robotic arm for positioning, a separate marking device for applying adherent material, and a cutting instrument for transection. This segmentation allows each component to be optimized for its specific function while maintaining overall system precision without requiring complete robotic automation of all subsystems.
Solution Approach 2:
An adherent material serves as an intermediary between the marking device and the cutting instrument. The material is applied along the desired transection line to create a visible guide that the robotic system can detect and follow, enabling precise cutting without requiring direct robotic control of every marking and cutting action.
2Device complexity
If manual surgical instruments are used for stomach transection, then device complexity is reduced, but manufacturing precision and reliability deteriorate due to lack of maneuverability and steadiness
Solution Approach 1:
The marking device applies adherent material along the desired transection line before the cutting instrument is used. This preliminary action creates a stable, visible guide that remains in place during the subsequent cutting process, ensuring precision without requiring the cutting instrument itself to be highly complex or difficult to maneuver.
Solution Approach 2:
The adherent material creates a physical copy or template of the desired transection path on the stomach surface. The robotic cutting instrument then follows this copied guide, allowing the system to achieve high precision by tracing a pre-established path rather than requiring complex real-time calculation and execution of the entire cutting trajectory.
3Manufacturing precision
If adherent material is applied to mark the transection line, then manufacturing precision is improved, but loss of substance increases due to material consumption
Solution Approach 1:
The adherent material is applied locally only along the specific transection line path rather than broadly across the entire surgical field. This localized application minimizes material consumption while maintaining high precision where it is most needed - along the cutting path. The marking device deposits material in a concentrated linear pattern rather than diffuse coverage.
Solution Approach 2:
The system changes the physical state or properties of the adherent material to enhance its visibility and detectability by the robotic system. By activating the material's optical or electromagnetic properties, the system achieves better detection with potentially less material, as the activated material provides stronger signal for the robotic vision system to track the transection line accurately.
