PYT-019A Stapler Anastomotic Seal Pressure Tester
The Peyotal PYT-019A Stapler Anastomotic Seal Pressure Tester incorporates a hydraulic/pneumatic dual-mode pressure boosting and stabilization system, enabling precise and linearly controllable pressure ramp rates. Featuring a 7-inch color touchscreen with an intuitive UI design, the system streamlines the setup of testing parameters, automated calibration routines, and real-time data analysis. Built to handle tissue specimens and staple lines across various surgical formats, the instrument measures seal pressure thresholds across a baseline range of 0 to 6 kPa (customizable up to 500 kPa) with a control accuracy of +/-0.12 kPa and standard test durations of 30 +/- 1 s. Equipped with an embedded thermal printer, automated data memory with power-loss protection, and a durable 12 kg benchtop frame, the PYT-019A serves as an essential quality control instrument for surgical stapler manufacturing lines, medical device inspection institutes, university research facilities, and hospital laboratories across Southeast Asia, Central Asia, Africa, and Latin America.
product details
The Stapler Anastomotic Seal Pressure Tester (Model: PYT-019A) is a specialized laboratory verification system designed and manufactured by Peyotal. Engineered to evaluate the burst pressure resistance, structural integrity, and hermetic sealing leak performance of staple lines formed by tubular staplers, linear cutters, and endoscopic staplers following tissue anastomosis, this instrument delivers reliable data to prevent post-operative fluid leakage and tissue separation.
Standards: Fully compliant with regulatory standards including YY/T 0245 (General Technical Requirements for Staplers) and related clinical performance evaluation criteria.

Q1: What is the exact laboratory testing principle and workflow for measuring stapler anastomotic pressure resistance?
A: The test evaluates the maximum fluid pressure a stapled tissue line can withstand before leaking or bursting. After performing a tissue closure using a surgical stapler, the anastomosed specimen is clamped into the tester’s specialized fixture. The hydraulic/pneumatic drive system delivers a linearly controlled fluid or air pressure into the specimen lumen. The instrument monitors pressure buildup over a standard 30 +/- 1 s duration, recording the exact pressure value at which fluid bypass or rupture occurs.
Q2: What types of surgical staplers can be evaluated on the PYT-019A?
A: The system accommodates a wide variety of surgical closure formats, including circular (tubular) staplers for gastrointestinal procedures, linear cutters, laparoscopic/endoscopic articulating staplers, and circular hemorrhoidal staplers. The customizable fixture architecture allows flexible testing across different staple line dimensions and tissue thicknesses.
Q3: Can the pressure testing range be customized for high-pressure medical devices?
A: Yes. While the standard configuration offers a baseline range of 0 to 6 kPa with +/-0.12 kPa accuracy for soft tissue anastomotic lines, the pressure delivery subsystem can be factory-customized to measure higher pressure thresholds up to 500 kPa for specialized vascular closures or high-strength synthetic graft testing.
Q4: What facility utilities and accessories are included in the delivery package?
A: The PYT-019A operates on standard single-phase electrical power (220V / 50Hz or 110V / 60Hz) and functions as a standalone benchtop system. The delivery container comes complete with the main testing instrument, standard anastomotic test fixtures, an integrated thermal micro printer, printing paper rolls, a power cable, and a comprehensive user manual.
