Abstract

The invention relates to the field of medical instruments, in particular to a puncture and drainage device for abdominal surgery in gastrointestinal surgery, which includes a housing case and a needle tube. The bottom surface of the transition case is also fixedly connected with a lamp body. The first optical coil, the second optical coil and the third optical coil in the extension direction are arranged concentrically, the diameter of the first optical coil is smaller than the diameter of the second optical coil, and the diameter of the second optical coil is smaller than the third optical coil. The diameter of the optical coil, the lamp body cover is arranged on the outside of the inner slide plate; through the concentrically arranged first optical coil, second optical coil, and third optical coil, the extension direction of the wound is estimated, and then rotated at this time Put the extrusion block connected to the rotating sleeve on the split extension line, and provide a resistance in the extension direction of the wound through the elastic pulling force of the spring rod, thereby preventing the wound from further cracking in this direction, thereby achieving prevention. The purpose of malignant dehiscence of the wound.

Description

technical field

[0001] The invention relates to the field of medical instruments, in particular to a puncture and drainage device for abdominal surgery in gastrointestinal surgery. Background technique

[0002] Gastrointestinal surgical puncture refers to the puncture technique in which a puncture needle is used to pierce the peritoneal cavity through the abdominal wall. Often used to examine the nature of the effusion to aid in the identification of the cause, or to administer intraperitoneally.
