Sealing connection method of vacuum sealing drainage device and orthopedic external fixator and vacuum sealing drainage system

Abstract

The invention provides a sealing connection method of a vacuum sealing drainage device and an orthopedic external fixator and a vacuum sealing drainage system. The system comprises the vacuum sealing drainage device and sealing rubber rings for connecting and sealing puncture needles on the orthopedic external fixator and the vacuum sealing drainage device, wherein the sealing rubber rings comprise elastic sealing sleeves and sealing bases which are positioned on the lower parts of the elastic sealing sleeves and extend outwards; and the elastic sealing sleeves and the sealing bases are mutually communicated. When the method is used, the sealing rubber rings are sleeved on the lower parts of the puncture needles of the orthopedic external fixator; after the puncture needles of the orthopedic external fixator are located, notches are cut on the positions, corresponding to the puncture needles of the orthopedic external fixator, of a porous foam cushion and a sealing film, the puncture needles penetrate through the notches, and the sealing film of the vacuum sealing drainage device and the porous foam cushion completely cover the surroundings of the puncture needles of the orthopedic external fixator; and then the sealing rubber rings are adjusted downward so that the bases of the sealing rubber rings are fit with the sealing film of the vacuum sealing drainage device, thus the sealing rubber rings completely cover and seal the notches of the sealing film in the positions of the puncture needles.

Description

technical field [0001] The invention relates to the sealing of an orthopedic external fixation device and a negative pressure sealing drainage device in negative pressure sealing drainage, specifically, a sealing connection method between a negative pressure sealing drainage device and an orthopedic external fixing device and a negative pressure sealing drainage system. Background technique [0002] Vacuum sealing drainage technology (vacuum sealing drainage, referred to as VSD) was pioneered by Dr. Wim Fleischman of ULM University in Germany in 1992, and formed a theoretical prototype for the drainage of extremity wounds; in 1994, Professor Qiu Huade of China applied the vacuum sealing drainage technology for the first time In general surgery, he pioneered the application of negative pressure sealing drainage technology in general surgery. The patent CN 2276350 authorized by Professor Wang Yanfeng and Qiu Huade in China on March 18, 1998 is the first patent of negative pres...

AI Technical Summary

Problems solved by technology

The above-mentioned sealing methods are very cumbersome in actual operation, and the surgeons need to perform repeated operations and exercises to master them, and the operation time is long, which makes the patients extremely painful

At the same time, due to the long-term operation, the patient will inhale a large amount of anesthetics, which will bring extremely serious side effects to the patient, and even cause brain death of the patient due to excessive inhalation of anesthetics.

Moreover, the above-mentioned method is still not firm in sealing, and it is extremely difficult to complete the sealing only by pasting the film, and the air leakage rate is over 90%, which can easily cause the therapeutic effect of the negative pressure closed drainage system to weaken or even fail due to air leakage.

Even if the seal is complete, the perforated needle patch will still lose its adhesiveness to the patch due to the accumulation of exuded tissue fluid and cause the seal to fail

However, after the treatment effect of the negative pressure sealing drainage system is weakened or even fails, infection is very likely to occur at the needle puncture site, and it will extend to the bone cavity along the puncture needle; Inside, the pus is extremely difficult to discharge, causing traumatic osteomyelitis, and the patient often suffers from unbearable pain.

However, the treatment of traumatic osteomyelitis is extremely expensive and difficult to treat, and may even persist for a long time. Repeated stimulation of the wound during treatment may also lead to squamous cell carcinoma.
