Description

Laparoscope cyst puncture anti-overflow positioning device

Technical Field

The application relates to the field of medical tools, in particular to a laparoscope cyst puncture anti-overflow positioning device.

Background

The progress of laparoscopic surgery has made possible the removal of most benign celiac cysts over the last 30 years. Laparoscopic surgery has the advantages of less trauma, shorter hospital stay and recovery time than traditional laparotomy, and is favored by patients due to its better aesthetic appeal.

However, in terms of the oncological safety of laparoscopic minimally invasive surgery, whether tumor resection satisfies the "tumor-free principle" has been controversial, mainly because rupture of the medical cyst and spillage of the contents of the malignant mass in laparoscopic minimally invasive surgery escalate the disease, resulting in the need for adjuvant chemotherapy and possibly compromising the overall survival of the patient.

The researchers think that serous cystadenoma and skin-like cyst rupture do not affect postoperative disease rate at present, because repeatedly washing the pelvic cavity in the operation generally does not affect causing the residue of the content of the skin-like cyst, and the ovarian mucinous cyst and the peritoneal mucinous cyst are tumors with different biological behaviors, so even if a little overflow occurs in the operation, the repeated washing does not affect the prognosis, but in fact, patients with ruptured and overflowed tumors exist in the operation, the follow-up requirements are tighter, and the patients and the operators face greater psychological pressure. While the poor outcome resulting from failed surgery is irreparable for unidentified individuals with early malignancy.

The iatrogenic cyst rupture and malignant mass content overflow risk of laparoscopic cyst resection is selected to be related to factors such as cyst size, nature, operation mode, operator operation capacity, laparoscopic equipment development and the like.
