During 200~300mmHg, using on the emulsion tube that the special Clip Applier of laparoscopic surgery closes at magnesium alloy hemostatic clamp, removal is noted
Emitter, hemostatic clamp is immersed in simulated body fluid, and experimental provision is placed in 37 degrees Celsius of constant temperature waters, is observed in 48 hours
Recording manometer registration changes, and such as sphygomanometers registration is not less than 150mmHg, then meet and require.
Working mechanism of the invention：
A kind of magnesium alloy laparoscopic surgery hemostatic clamp folder closes the external detection method of effect, is made up of three parts, first
It is divided into renitency test after magnesium alloy hemostatic clamp closure, can the hemostatic clamp that be used to observe after closure to the chucking power of emulsion tube
Reach 200~300mmHg；Part II is external chucking power test after magnesium alloy hemostatic clamp closure, after being used to observe closure
The situation of change of the external chucking power to emulsion tube of hemostatic clamp；Part III is the clamping during magnesium alloy hemostatic clamp soaks in vitro
Power is tested, and is used to observe in the in-vitro simulated body fluid immersion degradation process of magnesium alloy hemostatic clamp the change feelings to emulsion tube chucking power
Condition.When the detection of magnesium alloy hemostatic clamp meets three above means suitable simultaneously, then it is assumed that meet clinical requirement.
It is an advantage of the invention that：Stop from the pressure test of resistance, chucking power test, magnesium alloy after magnesium alloy hemostatic clamp closure
The folder that chucking power in blood folder immersion process tests three aspect comprehensive analysis sign Absorbale magnesium alloy hemostatic clamps closes effect；Behaviour
Work is easy, the degree of accuracy is high, good stability, and the detection magnesium alloy hemostatic clamp folder of energy system closes effect, used as animal experiment in vivo
