First, uses. The Microwave Ablation Syringe Rigidity Toughness Tester is a device used to evaluate the rigidity and toughness of the needle used in microwave ablation surgery. Microwave ablation is an interventional surgical technique used for ** tumors, which achieves the ablation of tumors by transferring microwave energy to tissues near the tumor to trigger tissue heating and necrosis.
In microwave ablation surgery, your doctor uses a needle to guide a microwave-clear catheter into tissue near the tumor. Therefore, the rigidity and toughness of the needle tube are very important for a successful operation. Rigidity refers to the hardness and bending resistance of the needle tube, while toughness indicates the flexibility and durability of the needle tube.
First, the implementation of standards.

Driven by modern medical technology, microwave ablation has become an important method for tumors. The rigidity, toughness and puncture force of the needle become particularly critical in the microwave ablation process. In order to better understand and evaluate the performance of different needles to improve the success rate and safety of microwave ablation procedures, scientists have developed the Microwave Ablation Needle Rigid Toughness Puncture Force Tester.
This test instrument has attracted a lot of attention in the medical industry with its powerful functions and accurate test results. It not only provides an accurate test of the puncture force of the needle tube, but also evaluates the stiffness and toughness of the needle tube. In microwave ablation surgery, the rigidity of the needle directly affects the stability and handling of the needle, while the toughness is related to the durability and safety of the needle. By testing the stiffness and toughness of the syringe, medical staff can choose a better performing needle to improve the success rate of microwave ablation surgery.
The working principle of this test instrument is very simple, but it is very accurate. First, the stylus tube to be tested is fixed on the test platform and a predetermined puncture speed and penetration depth are set. Then, through the locomotion system of the test instrument, the tip of the needle is pierced vertically downwards through the material to be measured. During the puncture process, the test instrument detects and records the change in the puncture force in real time. Finally, according to the test results, the stiffness and toughness index of the needle tube were analyzed, and a detailed test report was generated.
