Suture needle elasticity tester principle

Suture needle elastic tester is a professional for testing the physical properties of medical suture needles of efficient precision instruments, qualified medical suture needles in the puncture force, cutting force, hardness, elasticity, toughness, needle tip strength and other physical properties are required to meet the standard can be shipped to the market and used in
patients.

The application scenario of suture needles will not be said more here, and today Weisha Technology will elaborate on the suture needle elastic tester
in detail.

The design and manufacturing standard for the suture needle elasticity tester is Y Y 0043- 2005 Medical suture needle elasticity related requirements
.

It is a precision instrument specializing in detecting the elastic physical properties of suture needles
.

The same is true for the suture needle elasticity tester, we mentioned above puncture force, cutting force, hardness, elasticity, toughness, needle tip strength and other physical properties need to use the corresponding professional instruments, medical suture needle piercing force tester, medical suture needle cutting force tester, medical suture needle hardness tester, medical suture needle toughness tester, medical suture needle tip strength tester, etc
.

The requirements for physical properties are also described
in detail in the Y Y 0043-2005 medical suture needle standard.

First of all, let's briefly understand the classification of medical suture needles, medical suture needles are composed of needle tip edges, needle bodies, needle tails, pinholes and other parts; The tip of the needle can be divided into circular, positive triangle, reverse triangle, short edge triangle and triangular half-bend.

The needle body can be divided into straight, 1/2 arc, 3/8 arc
.

The specification code for medical suture needles is often expressed
as diameter X string length.

Next, we will take a look at the requirements of Y Y 0043- 2005 medical suture needle standard for the elastic physical properties of medical suture needles
.

Using elastic special tools, the end of the curved needle is fixed on the clamp to unfold the needle tip to the arc increase value specified in Table 3, and the scale value pointed by the needle tip is the amount of deformation, and the stitching needle should have good elasticity
.

It should be noted here that medical suture needles with a chord length of less than 12MM do not do elasticity tests, and string lengths above 12mm need to be tested
according to the standard requirements.

If the elastic performance of medical suture needles is not up to standard, there will be many safety hazards, which are easy to cause various medical accidents, so we should strictly control the quality of medical suture needles
.

If you happen to be a manufacturer of medical suture needles, it is recommended that you buy medical suture needle elasticity tester at the same time as you also buy medical suture needle piercing force tester, medical suture needle cutting force tester, medical suture needle hardness tester, medical suture needle toughness tester, medical suture needle tip strength tester and other testing instruments, so that the physical performance of medical suture needle testing items can be complete, of course, some suture needle tester suppliers will provide multi-function machine, You can buy a single instrument to inspect multiple items, which is both economical and affordable, and it is very cost-effective; The premise is that you can understand and find a reliable supplier, and from the supplier you can learn a lot of information that will help you!
