Description

Gynecological tumor taking-out forceps Technical Field The invention relates to the technical field of surgical forceps, in particular to a pair of gynecological tumor taking-out surgical forceps. Background Minimally invasive medical surgery is performed by cutting off a lesion part or repairing a defect under a microscope field of view through a percutaneous hole of a natural human body hole or a keyhole size, and the adherent tissues on human organs need to be grasped and separated in the surgical process. The minimally invasive surgery has the advantages of small minimally invasive damage, less bleeding and quick postoperative recovery, so that the forceps for the surgery are mostly in a long rod shape, and the tumor forceps (also called tumor extirpation forceps and tumor clamping forceps) are precise medical instruments specially used for grabbing, clamping, separating and extirpating tumor tissues in the surgery, are widely applied to the fields of tumor surgery, neurosurgery, general surgery and the like, and are particularly suitable for tumor excision operations of deep tissues such as intracranial, abdominal cavity, pelvic cavity and the like.
