Catheter device for surgical neurosurgery intervention

Abstract

The invention discloses a catheter device for surgical neurosurgery intervention. The catheter device comprises a base, a bottle body fixing mechanism is mounted at the top of the base, a negative pressure pressing mechanism is mounted in front of the base, the bottle body fixing mechanism comprises two first mounting plates, and the two first mounting plates are fixedly connected to the top, close to the two sides, of the base respectively. According to the catheter device for surgical neurosurgery intervention, collecting bottles can be effectively fixed through the bottle body fixing mechanism, and the situation that in the using process, the collecting bottles are toppled over due to the fact that a straightening guide pipe is dragged, then a catheter is pressed or bent, and final drainage fails is prevented; gas in the collecting bottles is pumped away through the negative pressure pressing mechanism, a negative pressure environment is created in the collecting bottles, hydrops ispumped into the collecting bottles due to the negative pressure effect, the pressing amplitude of an elastic air bag can be adjusted, the pressure in the collecting bottles is controllable, and the problem that drainage suction force is too large or insufficient is avoided.

Description

technical field [0001] The invention relates to the technical field of neurosurgery intervention equipment, in particular to a catheter device for surgical neurosurgery intervention. Background technique [0002] Interventional neurosurgery, also known as interventional neuroradiology, belongs to the category of interventional radiology. The first part of this book systematically introduces the anatomy of brain and spinal cord blood vessels related to interventional neurosurgery, catheters, embolization materials, imaging equipment, perioperative management, anesthesia, indications, prevention and treatment of complications and Various endovascular therapies used in interventional neurosurgery. Among them, the interventional catheter is the process of completely draining the effusion by using the principle of negative pressure, and is mainly used to implement closed drainage of the thoracic or abdominal cavity of postoperative patients. [0003] After searching, it is foun...

Problems solved by technology

[0004] But this drainage bottle also has the following defects: 1. The gas in the negative pressure device is discharged by manual extrusion to control the pressure value in the drainage bottle

However, such a drainage bottle not only has its internal air pressure unknown, but also cannot be adjusted accurately, which may easily cause the problem of excessive or insufficient drainage suction; The dragging of the straight catheter causes the bottle body to overturn, and then the catheter is pressed or bent, resulting in the failure of the final drainage, and the effect of use is not ideal
