Drainage tube with puncture needle and using method thereof

Abstract

A drainage tube with a puncture needle and a method of using the present invention, comprising a drainage cannula, a puncture needle and a drainage assembly, the drainage cannula includes a single-chamber sealing section, a multi-chamber sealing section and a multi-chamber opening section connected in sequence, the single The tube wall of the cavity sealing section is closed and at least one channel is formed inside, the tube wall of the multi-cavity sealing section is closed and the interior is divided into several channels, and the tube wall of the multi-cavity open section is notched along the length direction and the interior is divided into several channels; The end of the single-chamber sealing section away from the multi-chamber open section is connected with the puncture needle. Before the surgical wound is sutured, the puncture needle enters the cavity from the wound, punctures from the vicinity of the wound to the outside, pulls until the length of the drainage cannula left in the cavity reaches the preset length, and then cuts off at the single-cavity sealing section and withdraws The puncture needle, the single-lumen sealing section connected with the multi-lumen sealing section is connected to the drainage assembly from the cut-off. It can effectively avoid the risk of puncture needle wound and infection, and it is safer and more convenient to use, and has better drainage effect.

Description

technical field [0001] The invention relates to the technical field of drainage tubes, in particular to a drainage tube with a puncture needle and a usage method thereof. Background technique [0002] Drainage tubes are widely used in general surgery, trauma orthopedics, microsurgery, joint surgery, spine surgery, orthopedic surgery, and urology to drain organs such as wounds, chest cavity, brain cavity, gastrointestinal tract, and biliary tract. . During the operation, a local cavity will be formed for the operation. When drainage is required after the operation, the existing technology is to connect a puncture needle to the front end of the drainage tube (the end with the drainage hole), and there is a puncture part near the wound on the human skin , insert the puncture needle from the outside through the puncture part to pull the front end of the drainage tube to the inside of the cavity, then pull out the puncture needle from the cavity, and then fix the drainage tube f...

AI Technical Summary

Problems solved by technology

However, the existing structure and method of puncturing from the outside to the inside have the following defects: (1) it is difficult to control the puncture depth of the puncture needle during the puncture process, which can easily cause secondary damage to the wound; (2) the puncture needle When pulled out from the cavity, the force point of the puncture needle is relatively small, making it difficult to operate, and pulling out the puncture needle may damage the structure of the front end of the drainage tube; (3) Pulling out the puncture needle from the cavity will cause the longer The drainage tube is pulled into the cavity, causing the excessively long drainage tube to be bent under pressure in the cavity, turning into an angle, which will affect the drainage effect, and even the risk of infection or swelling caused by fluid reflux or retention

[0003] In addition, the drainage hole at the front end of the existing drainage tube is prone to blockage

Generally, postoperative drainage takes about 2 to 15 days. The drainage hole at the front end of the drainage tube is easily blocked by blood clots; During healing, new granulation will grow into the hole, causing drainage blockage; during the wound healing process, it is easy to squeeze the traditional drainage tube, resulting in unsmooth drainage; after drainage, the muscle tissue that grows into the hole will hinder the drainage. Pulling out the drainage tube, when the drainage tube is pulled out, will cause new damage to the newly grown muscle tissue, and the patient will feel intense pain
