Description

A single bone hole and double target point channel bleeding positioning device

technical field

The invention relates to a brain positioning device, in particular to a bleeding positioning device with single bone hole and double target point channels.

Background technique

Hypertensive cerebral hemorrhage is a common clinical disease, and the treatment method largely determines the prognosis and recovery. Minimally invasive perforation drainage, open surgery, and conservative treatment all cause varying degrees of damage to nerve function and affect the prognosis. With the deepening of research on cerebral hemorrhage, people have a relatively complete understanding of the pathology, clinical manifestations, treatment methods, and prognosis of cerebral hemorrhage. Surgical indications. There are many clinical surgical methods commonly used, mainly including craniotomy and hematoma evacuation, small bone window microsurgery, drilling hematoma aspiration and drainage, etc. Drill hole hematoma aspiration and drainage is based on cranial CT image examination to accurately determine the position, angle, and puncture depth of the puncture point, so as to achieve localized puncture of the hematoma cavity for hematoma aspiration or placement of related catheters for drainage. Practice has shown that through The use of burr hole hematoma aspiration and drainage to treat patients causes minimal trauma to patients.

At present, the single-channel drilling drainage is commonly used clinically, and simply looking for the hematoma center as the target may not be able to achieve a good suction effect.

The beneficial effects of the present invention are:

The device is aimed at patients with large-area cerebral hemorrhage. It adopts one hole and multiple targets, which is conducive to adequate drainage of hematoma and drainage of surrounding tissue fluid, which can relieve the pressure of cerebral edema on the brain tissue of patients, and is conducive to the prevention of cerebral vascular disease. Spasm occurs, helping to improve the cerebral circulation of patients, and speeding up the recovery of brain function after surgery, reducing surgical trauma, thereby improving the therapeutic value of patients with massive cerebral hemorrhage.
