Abstract

The invention provides an abdominal cavity puncture outfit for a medical operation and a puncture method, and relates to the field of medical operation supplies. The puncture outfit comprises a puncture outfit outer sheath and a puncture outfit inner core rod, wherein the outer side of the puncture outfit outer sheath is connected with a gas guide tube used for injecting a gas into the puncture outfit outer sheath; the puncture outfit inner core rod is arranged in the puncture outfit outer sheath in a penetrating manner, the length of the puncture outfit inner core rod is greater than that of the puncture outfit outer sheath, the puncture outfit inner core rod is detachably connected with the puncture outfit outer sheath, the end, penetrating through an inner cavity of the puncture outfit outer sheath, of the puncture outfit inner core rod is in a needle tip shape, a wire through hole is formed in the puncture outfit inner core rod, the wire through hole is formed along the axis of the puncture outfit inner core rod, and two sides of the wire through hole penetrate through two sides of the puncture outfit inner core rod respectively. The abdominal cavity puncture outfit solves the problem that an existing abdominal cavity puncture outfit is not easy to position. In addition, the invention further provides a puncture method of the abdominal cavity puncture outfit for the medical operation, which comprises the steps of puncture, primary location and secondary location. The invention can improve the accuracy of peritoneal cavity puncture.

Description

technical field [0001] The invention relates to the technical field of medical operation supplies, in particular to an abdominal puncture device for medical operation and a puncture method. Background technique [0002] The current treatment methods for renal cysts include laparoscopic renal cyst unroofing and decompression, and B-ultrasound-guided percutaneous renal cyst puncture and sclerosis. Laparoscopic surgery generally requires the establishment of three puncture channels, one of which is a laparoscopic observation port, and the other two are instrument operation ports. B-ultrasound-guided percutaneous renal cyst puncture and sclerosis is more minimally invasive than laparoscopic surgery, and there is only one puncture channel. However, since the cyst wall of the renal cyst is not removed, there is a certain chance of recurrence. Therefore, the most commonly used treatment method is laparoscopic decompression of renal cysts. [0003] Paracentesis is a commonly used ...
