Microwave Ablation Probe Tester YY 0899-2020 What are the detection items?

Microwave ablation therapy is one of the effective means of treating cancer, and an important auxiliary device for microwave ablation treatment is microwave ablation injection
.

Microwave ablation needles are directly acting on the human body, so there are very strict standards in terms of quality, microwave ablation needle tester is an efficient and precise instrument
to detect microwave ablation needle treatment.

Today, Wesa Technology will take you to see the standard requirements of microwave ablation needles and what are the microwave ablation needle testers? The standard basis for microwave ablation needles is the general requirements
of YY 0899-2020 medical microwave equipment accessories.

The manufacturing basis of the microwave ablation needle tester is also designed and manufactured according to the test methods and other relevant terms in the general requirements of the medical microwave equipment accessories of YY 0899-2020
.

In the general requirements of YY 0899-2020 medical microwave equipment accessories, strict requirements have been made for the physical size, puncture force, rigidity, toughness, needle connection firmness, surface material adhesion reliability, rod temperature detection function, sealing reliability of cooling components, prostate thermal condensation components, temperature measurement and positioning devices, etc.
of physical properties, electrical properties, chemical properties and biological properties of microwave ablation needles
.

Today we will talk in detail about the specific requirements
of physical performance.

1.
Physical size requirements The manufacturer should specify the shape, size and error requirements
of the accessories.

The use of universal gages, measured at the position specified by the manufacturer, should comply with the relevant requirements
.

2.
The puncture force needs to be punctured by the skin and tissue accessories, such as thermocoagulators, temperature measurement accessories, etc.
, which should have good puncture ability, and the puncture force should not be greater than 3 N
.

3.
Rigid skin and tissue puncture in vivo tissue thermal coagulation equipment accessories, such as thermocoagulators, temperature measurement accessories, etc.
, according to the provisions of the test of its deflection value should not exceed the provisions of
Table 1.

4.
Toughness needs to be punctured by skin and tissue in vivo tissue coagulation equipment accessories, such as thermocoagulators, temperature measurement accessories, etc.
, should have good toughness, and no rupture
occurs after the prescribed test.

5.
The needle connection is firm and the needle rod connection of the tissue thermocoalizer in the body should be reliable and should be able to withstand the tensile force specified in the table 2 without falling
off.

6.
Surface material adhesion reliability in vivo tissue condenser surface material should have sufficient adhesion reliability to ensure that the surface material does not fall off and damage
during contact with the tissue.

In addition to the requirements for the physical properties of the microwave ablation needle, the above mentioned requirements also include the rod temperature detection function, the sealing reliability of the cooling assembly, the prostate thermocoagulation assembly, the temperature positioning device, etc
.

The instruments needed to detect the physical properties of microwave ablation needles include microwave ablation needle puncture force tester, microwave ablation needle rigidity tester, microwave ablation needle toughness tester, microwave ablation needle connection firmness tester, microwave ablation needle seal reliability tester, microwave ablation needle rigidity toughness tester and many other microwave ablation needle testers
.
