Stapler Blade Sharpness Tester

It features a 7-inch K600+ core/dot-matrix 65-color 800*480 resolution touchscreen display with English and Chinese menu options.  Test parameters, production unit, production batch, and tester information can be freely entered.  Automatic data storage upon power failure is included, along with overload alarm and shutdown protection. Multi-level password protection is optional. Nominal specifications, pipe wall thickness, number of tests, pressurization, upward and downward movement, time, and calibration are all displayed. Test data can be printed directly from the onboard printer via the touchscreen LCD menu. It displays real-time blade sharpness force and peak force data, and can display the maximum sharpness and various other peak force curves.

Applications

The sharpness tester for stapler blades is mainly used to assess the sharpness of blades for medical staplers, ensuring the quality of surgical instruments and the surgical outcome. Specifically, the tester simulates the process of the blades cutting materials, measures and analyzes parameters such as the force and displacement during cutting, and then determines the sharpness value of the blades. This test result not only provides important quality - control evidence for medical device manufacturers but also offers reliable reference data for medical workers when choosing surgical instruments.

Test Procedures

1. Pre-test Preparation

Check the instrument's power supply (220V 50Hz) and component connections to ensure they are functioning correctly. Start the instrument and allow it to warm up to a stable operating state;

Calibrate the force sensor (ensuring an accuracy of ±0.01N), and prepare the test materials (such as 3-0 uncoated silk twisted suture as specified in YY0167-2005).

2. Sample and Test Medium Installation

Fix the stapler blade to be tested onto the instrument's dedicated fixture, ensuring the blade angle, position, and cutting path are aligned and there is no looseness/offset;

Install the test medium (such as standard suture) onto the cutting platform, adjusting its position to precisely align with the cutting edge of the blade.

3. Test Parameter Settings

Using the touchscreen interface, select the appropriate standard (YY/T 1797-2021), set the test speed (e.g., 0.05–600 mm/min), data acquisition frequency, and other parameters. Confirm and save the configuration.

4. Starting the Test

After confirming that the blade and medium are correctly positioned, click the "Start" button. The instrument will automatically simulate the cutting process, collecting and displaying cutting force, displacement, and other data in real time.

5. Test Process Monitoring

Observe the data changes on the interface to ensure that there are no abnormalities during the cutting process (such as blade jamming or medium displacement). If problems occur, pause and adjust immediately.

6. Test Completion and Cleanup

After the test is completed, the instrument will automatically shut down. Record/export the sharpness-related data (such as initial cutting force and displacement curve);

Loosen the fixture to remove the blade and remaining test medium, clean the fixture and cutting platform, turn off the instrument's power, and prepare the test report.

FAQs

1. What is the primary function of the Stapler Blade Sharpness Tester?

The Stapler Blade Sharpness Tester is mainly used to assess the sharpness performance of blades used in medical staplers. The instrument simulates the cutting process of stapler blades, measures parameters such as cutting force and displacement, and analyzes these data to determine blade sharpness. The test results provide objective and quantitative evidence for evaluating whether stapler blades meet sharpness and cutting performance requirements, helping ensure the quality of surgical instruments and the effectiveness of surgical procedures.

2. How does the tester support quality control and clinical instrument selection?

The Stapler Blade Sharpness Tester plays an important role in both manufacturing quality control and clinical instrument selection. For medical device manufacturers, the tester provides reliable sharpness data that can be used as quality-control evidence to verify product consistency and compliance with relevant standards. For medical workers, the measured sharpness values and cutting force curves offer reference data when selecting surgical staplers, supporting informed decisions that contribute to improved surgical outcomes and reduced operational risk.

3. What standards does the Stapler Blade Sharpness Tester comply with?

The tester is designed to support sharpness and cutting performance evaluation in accordance with YY/T 1797-2021. which specifies test methods for surgical blade sharpness and cutting performance. During testing, standard test materials such as 3-0 uncoated silk-like twisted strand sutures, as referenced in YY0167-2005. can be used to ensure consistency and comparability of test results under standardized conditions.

4. What test data and curves can be displayed during operation?

During operation, the instrument displays real-time blade sharpness force and peak force data on the touchscreen interface. It can also show the maximum sharpness value and various peak force curves generated throughout the cutting process. In addition, nominal specifications, number of tests, pressurization status, movement parameters, and timing information are displayed, enabling users to comprehensively monitor and analyze blade sharpness performance during each test.

5. What operational and data management features are integrated into the tester?

The Stapler Blade Sharpness Tester is equipped with a 7-inch industrial-grade capacitive touchscreen featuring English and Chinese menu options. Test parameters, production unit, batch number, and tester information can be freely entered. The system supports automatic data storage in the event of power failure, overload alarm and shutdown protection, and optional multi-level password protection. Test data can be printed directly using the built-in miniature printer, and professional software with access control supports standardized laboratory management.
