Critical Dimensions

Each instrument undergoes rigorous quality assurance testing to verify its performance in critical surgical procedures, ensuring absolute reliability in the operating room.

Surface Inspection

Every instrument is carefully examined for material integrity and surface perfection. We ensure a flawless satin finish, free from any residual lubricants, scratches, or foreign particles.

Dimensions Verification

Key measurements are checked using calipers, micrometers, and specialized gauges, then matched against technical design drawings to maintain strict consistency and pattern accuracy.

Function Tests

In addition to general inspections, function tests are used to verify instrument quality.

Cutting tests are performed on testing material. Scissors must not snag or bind when cutting appropriate layers of material. The heavier the scissors, the more layers of material they must cut. Blades must close smoothly without hesitation. Visual inspection is performed for burrs, especially on the cutting edge. Screw lock must be secure and slight amount of hinge play should exist when opened.

Ratchets are checked for proper holding action. Tips are verified as either sharp, blunt or semi-sharp. Ratchet mechanisms must close smoothly. Holding power is tested to make sure ratchet remain engaged during use. Ratchet teeth must align properly.

Closed jaws are checked against a light source to ensure that no substantial amount of light passes through. Jaws are clamped on plastic testing material. The impression should be clean and consistent. Teeth must mesh together closely . Jaws must be properly aligned. Ratchets must engage crisply and smoothly. While engaged at the first ratchet tooth, instruments should not open when tapped lightly against the edge of a table.

Cutting tests are performed with the appropriate test material. Forceps must cut cleanly with the front half of the jaws. Tips must close properly from the top to the middle of the jaws.

Jaws must close tightly so that no light shines through the front 2/3 of closed jaws tested against a light source. Must hold suture material, and pass similar tests as outlined under forceps.

Cutting tests are performed according to the recommended maximum capacity of each instrument.
