Frequently Asked Questions
How large is the healing surface after tissue shedding?
The shrinkage of the inner lumen is unrestricted, resulting in a very small healing surface. This prevents the formation of small granulomas commonly associated with standard rubber band inner diameters. 
Some doctors feel the anoscope aperture is too large and hard to get used to.
The large aperture design helps expand the mucosa to prevent post-ligation anal stricture. We also offer day-surgery anoscopes with smaller apertures.
Under what circumstances might vacuum leakage occur in the device body?
Vacuum leakage typically occurs if the negative pressure release valve is not fully closed.
What is the inner diameter of the barrel's inner tube?
The inner diameter is approximately 0.8 cm. The suction volume of the barrel is fixed, preventing over-suctioning regardless of suction duration.
Will bleeding occur after the ligated tissue sheds?
With optimal ligation tightness, postoperative bleeding caused by incomplete closure is extremely rare. Even if minor oozing occurs, most cases require no intervention.
First-time users often worry that quantitative tightening might not lock securely, resulting in insufficient tissue grasp.
Operators can manually pull the tightening knob to feel and verify the degree of tightness.
Why does the elastic band remain on the inner tube without capturing mucosal tissue after firing?
This is caused by an installation error where the barrel and the slot were not securely connected, preventing the inner tube from retracting after firing.
Why does the elastic band stretch into a straight line without capturing any mucosal tissue after firing?
The elastic band failed to catch any tissue. By design, the elastic thread knot straightens out into a line when no tissue is bound inside.
Will quantitative tightening exert excessive force and damage the mucosa?
The force of quantitative tightening is precisely controlled. Supported by cumulative data from tens of thousands of clinical cases, it is completely safe for use.
How should larger hemorrhoidal masses be ligated?
First, place 1-2 suspension ligation points above the larger mass. Once the mass is reduced in volume, perform base ablation ligation on the remaining mass.
How long does it usually take for the ligated tissue to fall off?
Approximately 10 days.
