Comparison Item
|
Hysteroscopic Cold Knife System
|
Traditional Hysteroscopic Electrosurgical Resection
|
|
Working Principle
|
Pure mechanical manipulation (scissors, forceps, cold knife), no energy input or heat generation.
|
Uses thermal effect generated by high-frequency electric energy for tissue cutting and coagulation.
|
|
Tissue Injury
|
No thermal injury; excellent protection of the endometrium, with low risk of postoperative adhesions.
|
Thermal burns may occur, which can damage the basal layer of the endometrium and increase the risk of adhesions.
|
|
|
|
|
|
Surgical Precision
|
Extremely high; capable of fine adhesion separation and resection of small polyps.
|
High, but heat conduction may cause tissue carbonization, affecting pathological judgment.
|
|
Applicable Scenarios
|
Intrauterine adhesion separation, uterine septum resection, endometrial polyp resection, submucosal myomectomy, etc.
|
Resection of larger myomas, surgeries requiring high hemostasis requirements.
|
|
Complication Risk
|
Low, mainly mechanical injury.
|
Relatively high, including uterine perforation, bleeding, infection, intrauterine adhesions, etc.
|
|
Postoperative Recovery
|
Fast, short hospital stay, mild pain.
|
Relatively slow; postoperative discharge and abdominal pain may occur.
|
|
Pathological Specimen Quality
|
Good, intact tissue, conducive to pathological diagnosis.
|
Average; tissue carbonization may affect pathological results.
