Technical Field

The invention relates to the technical field of medical surgical instruments, in particular to an operation positioning device for intracerebral lesions.

Background

Cerebral hemorrhage is a common neurosurgical disease; cerebral hemorrhage has high disabling fatality rate, and the operation of clearing intracerebral hematoma is often required to be performed as early as possible during the treatment of the cerebral hemorrhage; the key to the success of cerebral hemorrhage surgery is the precise location of intracerebral hematoma by the operating physician. At present, when cerebral hemorrhage surgery is performed, a doctor adopts a freehand puncture method, but whether puncture is successful or not mainly depends on experience and feeling of an operator, and the method has great uncertainty and risk.

The existing intracerebral lesion accurate positioning system used for the cerebral hemorrhage operation is mainly a frame stereotaxic apparatus and a frameless stereotaxic navigation apparatus; however, these two types of medical equipment are expensive and have large volume; is not beneficial to be popularized in most medical institutions, especially basic medical units;

accordingly, a surgical locator device for an intracerebral lesion is presented herein.
