Electric Stapler With Independent Drive, Rotation, and Swing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric endoscopic staplers lack intelligence in their operation, as all three functions (swing, rotation, and closing/firing) are driven by motors, leading to suboptimal performance and requiring manual dexterity from the doctor.
Innovation Solution
An electric stapler with independent main drive, rotating, and swing assemblies, each driven by a motor and gear assembly, allowing for intelligent operation through a control system with guide buttons for one-handed use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If all three operations (swing, rotation, closing/firing) are driven by motors, then the stapler should be fully automated, but the current implementation is not intelligent enough and requires manual dexterity
Solution Approach 1:
The stapler is divided into three independent motor-driven assemblies: swing assembly (driving oscillation), rotating assembly (driving rotation), and main driving assembly (driving closing and firing). Each assembly operates independently under electronic control, achieving full automation while maintaining operational simplicity through button control.
Solution Approach 2:
The patent replaces manual mechanical operation with an electronic control system that coordinates three motors. The control system receives signals from guide buttons and automatically controls the swing, rotation, and firing sequences, substituting complex manual mechanical coordination with electronic automation.
2Device complexity
If manual endoscopic stapler is used, then the structure is simpler, but it requires certain requirements for the doctor's actual operating skills and may cause pulling and tearing of tissues
Solution Approach 1:
The patent replaces manual mechanical stapling with an electrically controlled system that automates the closing and firing processes. The main driving assembly controls the cartridge assembly's movement precisely, eliminating the pulling and tearing issues associated with manual operation while improving reliability.
Solution Approach 2:
The stapler performs self-adjustment and self-execution of the stapling process through automated control. The system automatically coordinates the swing, rotation, and firing actions without requiring manual dexterity, making the device self-sufficient in performing the surgical task reliably.
3Extent of automation
If electric stapler with multiple motor assemblies is implemented, then full automation is achieved, but the device complexity increases
Solution Approach 1:
The complex automated system is segmented into three functional modules (swing assembly, rotating assembly, main driving assembly), each with its own motor and gear assembly. This modular segmentation manages complexity by organizing functions into independent, manageable units that can be controlled separately yet coordinated electronically.
