Stapler Nail Excitation Force Tester Testing Machine
The Stapler Nail Excitation Force Tester Testing Machine is a medical device quality inspection system used to evaluate whether the operating force required during the firing (activation) process of a surgical stapler meets specified standards.
It is mainly used in:
- Medical device manufacturing quality control
- R&D and product validation
- Regulatory testing (e.g., CE, FDA compliance)
- Final production inspection
The Stapler Nail Excitation Force Tester Testing Machine is the manual firing action of a surgical stapler using a motor-driven actuator. During the process, a high-precision force sensor (load cell) continuously records the applied force. The system also tracks displacement and speed, generating a force–displacement curve and calculating key parameters such as peak force and average operating force.
To ensure the stapler operates within a safe and ergonomic force range—neither too difficult to fire nor too easy, which could affect surgical safety and performance.

Main Functions
1. Fixture and Positioning
The surgical stapler is securely mounted on a dedicated fixture to ensure a consistent test angle and stable positioning throughout the measurement process.
2. Simulation of Firing Action
The system uses a servo motor or electric linear actuator to simulate the manual firing process of the stapler.
It drives the firing mechanism at a predefined and controllable speed, replicating the motion of a human operator.
3. Real-Time Force Measurement (Core Function)
During the firing process, a high-precision load cell installed on the driving mechanism continuously measures the applied force in real time.
The force data is typically displayed in Newtons (N) or gram-force (gf).
4. Synchronized Displacement Tracking
At the same time, the system records displacement (mm) and movement speed (mm/s).
These parameters are used to generate the key output:
Force–displacement curve
This curve is essential for evaluating the mechanical performance and operational smoothness of the stapler.
5. Data Analysis and Evaluation
The software automatically processes the collected data and calculates key indicators, including:
- Peak force
- Average force
- Force fluctuation range
- Compliance with preset standards
Finally, the system generates:
- A detailed test report
- Force–displacement curve graphs
- Pass/Fail evaluation results
