Description

Technical Field

[0001] The invention belongs to the technical field of circumcision devices, and in particular relates to an advanced circumcision device. Background Art

[0002] A circumcision device is a medical device used to assist in completing circumcision surgery. It is used to simplify the positioning and tightening of the elastic coil. During the circumcision surgery, the circumcision device may come into contact with the patient's penis in a squeezed manner. The inner ring structure of the circumcision device adopts a tubular structure with a fixed size. During use, when the patient's penis size is inconsistent with the size of the inner ring, directly putting it on will cause discomfort to the patient and squeeze the body, resulting in inaccurate positioning or asymmetric appearance after circumcision. At the same time, in the early design, the positioning section of the outer ring was relatively low. When the patient's circumcision process was relatively mild, the skin peeling extension area was shorter, resulting in the inability to extend to the positioning section for positioning operations, affecting the smooth progress of the operation. Summary of the Invention
