Surgical Stapler Current-Sensing Control for Anastomosis Completion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing surgical staplers, operators must manually determine whether an anastomosis action is completed, which affects the progress and efficiency of surgical procedures.
Innovation Solution
A surgical stapler with a control part that acquires real-time drive current values and jump current average values, determining differences and comparing them to thresholds to automatically control the drive part to stop or continue operations, thereby automating the determination of anastomosis completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual determination of anastomosis completion is used, then operator control is maintained, but surgical efficiency decreases due to continuous monitoring requirements
Solution Approach 1:
The surgical stapler performs self-detection of anastomosis completion through the control part monitoring drive current values. The system automatically determines when the stapling action is complete without requiring continuous operator assessment, enabling the device to monitor and judge its own operational status.
Solution Approach 2:
The patent replaces manual operator judgment with an automated electrical detection system. The control part uses drive current monitoring and comparison with threshold values to automatically determine anastomosis completion, substituting the mechanical/manual assessment process with an electrical sensing and control system.
2Measurement precision
If automated drive current monitoring is implemented, then anastomosis completion detection precision improves, but device complexity increases
Solution Approach 1:
The control part continuously monitors the drive current value during operation and compares it with threshold values in real-time. This feedback mechanism allows the system to automatically detect when the drive current changes indicate completion of the anastomosis action, providing precise detection through continuous electrical parameter monitoring.
Solution Approach 2:
The patent detects anastomosis completion by monitoring changes in the drive current parameter. The control part compares the real-time drive current value with predetermined threshold values, and when the current exceeds the threshold, it automatically determines that the stapling action is complete, utilizing electrical parameter changes as the detection basis.

AI summary
A surgical stapler and a control method therefor. A control part of the surgical stapler is used to acquire a real-time drive current value and a jump current average value of a drive part; then, determine the difference value between the drive current value at a current moment and the drive current value at a previous moment; compare the difference value to the jump current average value, if the difference value is greater than the jump current average value, control the drive part to stop working. Thus, an operator does not have to determine by his or herself whether anastomosis action is completed before operating the surgical stapler, thereby increasing surgical efficiency.
