Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopic suturing technologies face issues with high friction surfaces on suturing beads, difficulty in bead discharge through suturing needles, waste of suturing beads, and inability to verify proper bead discharge, leading to inefficient and inaccurate surgeries.
Innovation Solution
A suturing bead with an arc-shaped cross-section and inclined suture-penetrating part, a suturing needle equipped with a bead stopper and dummy bead for controlled discharge, and a side suction cap with a perpendicular suction port and mirror part for visual verification of bead placement, ensuring accurate and efficient suturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a prior suturing bead is used, then it can perform suturing function, but it has a large friction surface with respect to a suture making it difficult to move through a suturing needle
Solution Approach 1:
The suturing bead is designed with a curved surface and an arc-shaped cross-section, which reduces the friction surface area compared to flat-sided beads. The curved geometry allows smoother passage through the suturing needle while maintaining effective suturing contact with tissue.
2Reliability
If a prior suturing needle is used, then it can deliver suturing beads, but there is no way to check whether the suturing bead is discharged properly resulting in waste of suturing beads
Solution Approach 1:
A mirror surface is integrated into the side suction cap, allowing the surgeon to visually verify bead discharge through reflected light. This feedback mechanism enables real-time confirmation of successful bead delivery, preventing waste from failed discharges.
Solution Approach 2:
The mirror surface utilizes light reflection properties to create visual indicators of bead discharge status, enabling optical detection of the suturing process outcome without requiring additional sensors or complex detection systems.
3Loss of information
If a prior vacuum cap is used, then it can perform suction function, but it cannot check whether the suturing needle penetrates the sucked organ and whether the suturing bead is discharged properly
Solution Approach 1:
The side suction cap integrates multiple functions: suction capability, visual verification through mirror reflection, and observation of needle penetration and bead discharge. This multi-functional design provides comprehensive surgical information without requiring separate verification devices.
Solution Approach 2:
The mirror surface acts as an intermediary that reflects light from the surgery area, enabling indirect visualization of bead discharge and needle penetration status. This optical mediator provides verification capability without requiring direct line-of-sight or additional complex imaging systems.
4Productivity
If multiple suturing beads are discharged for one stitch, then suturing can be performed, but it increases surgery time and surgeon fatigue
Solution Approach 1:
The inclined suture-penetrating part replaces complex mechanical bead advancement mechanisms with a geometric solution. The inclination angle facilitates automatic bead movement through the needle during discharge, reducing the number of beads needed and simplifying the suturing process.
