Description

Minimally invasive positioning device for intracranial hematoma

Technical Field

The utility model relates to an intracranial hematoma wicresoft location, in particular to intracranial hematoma wicresoft positioner belongs to intracranial hematoma wicresoft location technical field.

Background

In the existing life, intracranial hematoma is a common disease and frequently occurs disease clinically, in the existing technology, two operation methods for treating the intracranial hematoma are provided, one is treatment by craniotomy, the operation difficulty is high, the danger is high, the treatment cost is high, and the pain and the economic burden of a patient are increased. The other is that a minimally invasive technology for removing the intracranial hematoma is adopted, although the technology is safe, effective, low in cost and small in wound, in the practical clinical operation, the used instrument is greatly interfered by human factors in the aspect of puncture accuracy, a puncture needle tip is not easy to hit a target point, the position of the puncture needle tip is not matched with the position of the target point selected before the operation, and the treatment effect is directly influenced if the puncture needle tip is penetrated to the edge of the hematoma. Therefore, the size and the position of the hematoma need to be determined before minimally invasive operation, and then positioning is carried out, so that the puncture needle can conveniently enter the place where the hematoma is located for treatment.

However, the existing minimally invasive positioning device for intracranial hematoma still cannot accurately position the blood clot in the brain when in use, thereby possibly causing huge medical accidents and having unthinkable consequences.
