Drainage tube with puncture needle and utilization method of drainage tube

Abstract

The invention discloses a drainage tube with a puncture needle and a utilization method of the drainage tube. The drainage tube comprises a drainage cannula, the puncture needle and a drainage component. The drainage cannula comprises a single-cavity sealed section, a multi-cavity sealed section and a multi-cavity open section in sequential communication. At least one passage is formed in the single-cavity sealed section which is sealed, the multi-cavity sealed section is sealed and internally partitioned into a plurality of passages, the multi-cavity open section is provided with a notch along the length direction of the wall and internally partitioned into a plurality of passages, and one end, away from the multi-cavity open section, of the single-cavity sealed section is connected with the puncture needle. Before suture of a surgical wound, the puncture needle enters the cavity from the wound and punctures outside from a nearby part of the wound, then pulling is performed until length of the drainage cannula indwelled in the cavity is equal to a preset length, cutting is performed at the single-cavity sealed section to withdraw the puncture needle, and the single-cavity sealed section connected with the multi-cavity sealed section is connected with the drainage component at the cut position. Risks of infection and wound stabbing caused by the puncture needle can be effectively avoided, safety, convenience and quickness are realized, and better drainage effects are achieved.

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 method of use thereof. Background technique [0002] Drainage tubes are widely used in general surgery, trauma and orthopedics, microsurgery, joint surgery, spine surgery, bone surgery and urology and other departments to drain wounds, thoracic cavity, brain cavity, gastrointestinal tract and biliary tract. . During the operation, a cavity is formed for the operation. When drainage is required after the operation, the prior art 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 on the human skin near the wound. , Insert a puncture needle from the outside through the puncture part to pull the front end of the drainage tube to the inside of the cavity, and then pull the puncture needle from the cavity, and then fix the drainage tube for drainage. Fixing...

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
