Circular Tubular Stapler With Audible Firing Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Doctors cannot visually observe or feel the firing state of a circular stapler during surgical operations, leading to poor user experience.
Innovation Solution
A circular stapler with an indicator that moves between two positions, striking a strike part to emit a sound when firing is complete, providing auditory feedback on successful completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional circular stapler is used without feedback mechanism, then the structure remains simple, but the operator cannot observe or feel the firing state leading to poor user experience
Solution Approach 1:
The patent implements an audible feedback mechanism where a strike part (bell) and striker provide auditory confirmation when the anvil assembly reaches the correct position relative to the cartridge assembly. This feedback loop allows the operator to know when firing is complete without adding complex electronic systems.
Solution Approach 2:
The patent replaces potential electronic or optical feedback systems with a simple mechanical audible indication system. The strike part and striker create sound through mechanical impact, providing reliable feedback without requiring batteries, sensors, or electronic components.
2Reliability
If no audible indication is provided, then the device structure remains simple, but the operator cannot know when firing is completed
Solution Approach 1:
The audible indication system provides immediate feedback to the operator when firing is complete. The strike part produces a distinct sound that confirms the anvil assembly has reached the correct position, ensuring reliable operation.
Solution Approach 2:
While not using color changes directly, the patent employs a similar sensory feedback principle using sound. The audible indication serves as a sensory signal (analogous to visual color changes) that clearly indicates the firing state to the operator.
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
Enhances user experience by allowing operators to know the firing state of the stapler through an audible indication, improving operational confidence.
Implementation Method 1
the first end of the indicator returns to the first position area from the second position area, strikes the strike part and emits a strike sound

AI summary
A circular tubular stapler, comprising a stapler body, a handle assembly, and a staple pushing rod (75). A pointer (5) and an impact portion are further provided in the stapler body, and the pointer (5) can be rotatably connected to the stapler body; when the stapler is in an initial state, the pointer (5) is located in a first position area, and the pointer (5) presses against the impact portion; when the stapler is in a trigger state, the pointer (5) moves to a second position area, and the pointer (5) is separated from the impact portion; when the stapler is triggered completely, the pointer (5) returns from the second position area to the first position area, and collides with the impact portion to produce an impact sound. The impact portion is provided in the stapler body; when the trigger is completed, the pointer (5) returns from the second position area to the first position area, and can collide with the impact portion to produce the impact sound; an operator is prompted to successfully complete the trigger by means of the sound, the operator can timely grasp the trigger state of the stapler, and the use experience is improved.
