Detailed Description
In order to make the objects, technical solutions and advantages of the present invention easier to clearly understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
As shown in fig. 1, the abdominal puncture drainage device comprises a drainage main pipe 2 and a puncture needle 1 arranged inside the drainage main pipe 2, wherein the drainage main pipe 2 is of a hollow structure, the inner diameter of the drainage main pipe 2 is slightly larger than the diameter of the puncture needle 1, the diameter of the puncture needle 1 is 18-23G, the damage to tissues is small when the diameter is thin, the puncture needle 1 can clearly develop under ultrasound, and medical staff can puncture a focus under direct vision of ultrasound;
