Suture needle triangle needle edge cutting force tester 

Use a 7-inch LCD display screen, with the Chinese menu display.The menu on the LCD screen is controlled by the keyboard, which automatically loads the cutting force, automatically outputs the data report, and prints the test data onboard.Nominal specification, test load, printing, test, uplink, downlink, time, and calibration.

Part of the list:
1. One host machine 2. One set of printing paper 3
7. Instruments * upgrade services according to national standards

test procedure:

The schematic value error of the instrument shall not be greater than 0.98 N.

The instrument should have a correction level and shock-proof device, and the needle clip should be adjusted and stable during use.

The transmission of the instrument shall be sensitive and reliable, and the pointer shall stop automatically when the suture is cut.

Suture line requirements

Sutures is 4-0 coated twisted medical wire, its performance requirements shall meet the requirements of XY0167-2005.

The suture surface shall be clean and dry without knotted defects.

Sutures shall not exceed the service period specified in the standard.

testing program

Suture needles, instruments, and sutures were placed in a 22℃ x 2g ℃ environment for at least 1 h and tested under the same conditions.Position the suture needle (one side of the suture needle plane) down on the fixture, fold the suture from 9 c m to 10 c m, and then hang it on the upper fixture to U-shape, and insert the front section of the triangular needle blade (1 / 3 of the total length of the triangular blade mouth) for cutting.When the triangular edge cuts the seam line, the scale indicated by the pointer is the cutting force of the triangular edge.

Press the work control switch button to restore the pointer to the ether.

Turn the needle clamp for 180° to determine the flat edge cutting force of the other side of the suture needle with the same test method

The two-plane blade edges of each triangular suture needle were cut once, and the arithmetic average value was taken.
