Brain abscess precise puncture drainage device

Abstract

The invention discloses a brain abscess precise puncture drainage device which is composed of a puncture drainage tube and a metal guide core in the puncture drainage tube, the puncture drainage tube is designed to be of a hollow cylinder structure, the two ends of the puncture drainage tube are open, and the far end of the metal guide core is provided with a puncture head with an electromagnetic navigation function, preferably a navigation probe, in an operation process, electromagnetic navigation is utilized, the position of the current puncture head can be determined, whether deviation exists or not can be accurately judged in the operation process, and meanwhile the position relation between the puncture drainage catheter and the abscess wall can be observed. After the puncture head reaches the abscess wall, the metal guide core is electrified, and the current reaches the puncture head through the metal guide core, so that the abscess wall can be easily opened. According to brain abscess precise puncture drainage device, the surgical operation difficulty can be reduced, the accuracy is improved, the risk of pus exosmosis is reduced, and the surgical safety is improved.

Description

technical field [0001] The invention belongs to the technical field of brain abscess puncture, in particular to a precise puncture and drainage device for brain abscess. Background technique [0002] Surgical treatment of brain abscess includes craniotomy and abscess resection and abscess drainage. Craniotomy for abscess resection is relatively traumatic, and there is a risk of secondary brain tissue damage, especially when the abscess is located in an important functional area or deep in the brain, the operation is difficult and may leave permanent dysfunction. Abscess puncture and drainage is a widely used treatment method at present, and it is the first choice for the treatment of deep brain and multiple brain abscesses. However, the current defects in brain abscess puncture are: when the puncture needle reaches the wall of the abscess, the puncture needle is difficult to puncture due to the obvious and thick fibrosis of the abscess wall. Excessive force may slip, easily...

AI Technical Summary

Problems solved by technology

However, the current defects in brain abscess puncture are: when the puncture needle reaches the wall of the abscess, the puncture needle is difficult to puncture due to the obvious and thick fibrosis of the abscess wall. Excessive force may slip, easily damage the surrounding structures, and the strength is difficult to grasp. Moreover, multiple punctures are likely to cause pus outflow and spread of infection. In addition, because abscesses are generally deep, whether the puncture needle can reach the wall of the abscess is mainly based on the preoperative brain scan to determine the location of the abscess, and then calculate the puncture path and depth. This mainly depends on the doctor's experience, so the actual operation is more difficult and the risk is higher
