Description

Puncture cannula with panoramic image function

Technical Field

The utility model relates to the field of medical instruments, in particular to a puncture cannula with a panoramic image function.

Background

The laparoscopic surgery is a surgery that a surgeon performs outside the body through an endoscope lens and surgical instruments inserted into the body.

Laparoscopic surgery generally requires that a plurality of small incisions with the diameter of 5-12 mm are established at different parts of the abdomen by using puncture outfits, 3-5 holes are mostly adopted for operation, and an endoscope and various special surgical instruments are inserted through the small incisions. The surgeon operates with various special surgical instruments in vitro by observing various images of the inside of the abdominal cavity captured by the endoscope lens. The endoscope used in the laparoscope provides illumination through a cold light source and displays the shot images on a special screen in real time. The operation has the advantages of small operation wound, small scar of abdominal incision, beautiful appearance, quick recovery after operation, short hospitalization time, light pain after operation, the same treatment effect as the operation for opening abdomen, etc.

Laparoscopic surgery requires a separate incision for the endoscope, which sometimes cannot be seen completely in the abdominal cavity due to the restriction of the operating position of the endoscope, and needs to be seen by adjusting the angle of the endoscope. For the patient, the addition of one incision undoubtedly brings about greater pain and longer recovery period.
