Spiral puncture outfit with pneumoperitoneum device

Abstract

The invention relates to a spiral puncture outfit with a pneumoperitoneum device with simple and convenient operation and safe use and a use method thereof. The spiral puncture outfit consists of a sleeve sheath with a handle at the tail part and a core bar with a core bar seat at the tail part, wherein the core bar is a hollow tube, the front end of the core bar is provided with a needle hole, an inner cavity of the core bar is sequentially provided with a pneumoperitoneum needle with a resetting device and an air conduit from the front end of the core bar to the tail end of the core bar, the head of the pneumoperitoneum needle extends out of the core bar from the needle hole, and the air conduit is sleeved outside the tail end of the pneumoperitoneum needle; and one end of the resettingdevice is connected to the air conduit and fixed on the inner wall of the sleeve sheath, and the other end of the resetting device is fixed on the pneumoperitoneum needle. When the sleeve sheath withthe handle is combined with the core bar with the core bar seat and the front end of the core bar completely extends out of the sleeve sheath, a vent hole is arranged on the side wall of the core barlocated below a rubber one-way valve, and an opening at the upper end of the air conduit and the inner wall of the core bar seat are not neighboring. The invention has the advantages of simple and convenient operation, reduced surgery risks, and the like.

Description

technical field [0001] The invention relates to a medical device, in particular to a spiral puncture device with a pneumoperitoneum device. Background technique [0002] At present, in laparoscopic surgery, the pneumoperitoneum is generally first established with a vesicle needle, and then punctured with a puncture device, which takes a long time to perform the operation, and is likely to cause damage during the puncture into the abdomen. The incidence of large vessel injury in the retroperitoneum caused by the first puncture in laparoscopic surgery ranges from 0.05% to 0.11%. Laparoscopic cholecystectomy (LC) is often complicated by vascular injury due to the use of Veress needles, puncture cones and other instruments, and death due to vascular injury The rate was 0.02%, accounting for 21.9% of LC deaths; cases of omental blood vessels, intestines, liver or other tissues and organs were occasionally injured by abdominal puncture and puncture needle.
