Description

Single-hole incision protective sleeve free of inflation through vagina

Technical Field

The utility model relates to a transvaginal inflation-free single-hole incision protective sleeve, and belongs to the field of medical instruments.

Background

Transvaginal natural orifice endoscopic surgery (V-NOTES) is a transvaginal natural orifice endoscopic technique. The minimally invasive surgery mode is that an endoscope enters a body cavity through a natural body cavity channel of a vagina, an operation channel and a pneumoperitoneum are established, and various pelvic cavity and abdominal cavity surgical operations are completed under the endoscope. With the rapid development of minimally invasive surgery and the improvement of the humanistic care concept of doctors, V-NOTES is gradually used in various gynecological operations, and is popular among more and more young women and gynecological doctors due to the unique advantages of no scar on skin, light postoperative pain, quick recovery, more minimally invasive and more attractive appearance. The existing common V-NOTES provides the space required by the operation by manufacturing the CO2 artificial pneumoperitoneum, an air leakage-proof incision protector is needed to be used when the artificial pneumoperitoneum enters the abdominal cavity platform through the vagina, a valve needs to be opened when surgical instruments are replaced, the air leakage in the abdominal cavity is prevented, and the V-NOTES has the following defects: the inflation is needed, and the valve is required to be opened when the surgical instrument is replaced every time, the structure is complex, and the operation is troublesome.

Disclosure of Invention
