Description
Technical Field
The invention belongs to the field of medical instruments, and particularly relates to a novel incision protection sleeve for single-hole endoscopic surgery.
Background
Single lumen endoscopic surgery refers to surgery in which the surgeon inserts a tiny endoscope and surgical instruments through only one suitable surgical incision and directs the surgical instruments through images transmitted to a monitor. Such a surgical operation is called laparoscopic surgery when performed in the abdominal cavity and as thoracoscopic surgery when performed in the chest cavity.
Through many years of development, surgeons often place incision protection sleeves in incisions during single-hole endoscopic surgery, and the incision protection sleeve has the advantages of protecting the incisions to the greatest extent, reducing injuries such as intercostal nerves and blood vessels, reducing postoperative pain and bleeding, and expanding the incisions through flexible channels, thereby being more beneficial to surgical implementation. The existing incision protection sleeve comprises a bottom end ring, a top end ring and a flexible channel, wherein the bottom end ring is placed into a patient, the top end ring is left outside the patient, and the flexible channel is arranged between the inner ring and the outer ring to prop open an incision. However, in actual surgical procedures, such incision protection sleeves are still inconvenient to use and are not particularly suited to the needs of single hole endoscopic surgery that are currently becoming popular. In clinical practice, the endoscope and the surgical instrument are required to pass through the single hole of the flexible channel, and the condition that the endoscope and the surgical instrument are mutually interfered often occurs due to the asynchronous movement of the endoscope and the surgical instrument.
In single hole surgical procedures, surgeons are accustomed to placing a scope on one side or highest of a single hole of a flexible channel, and surgical instruments are frequently operated and switched on the other side or below. In addition, in some surgical operations, a surgeon often needs a sealed and inflated operation environment, such as artificial pneumothorax down thymoma excision, artificial pneumoperitoneum down abdominal cavity operation, etc., which requires a single hole incision protection sleeve with a sealed accessory.
