METHOD FOR MINIMALLY INVASIVE REMOVAL OF INTRACRANIAL NON-TRAUMATIC HEMATOMAS Russian patent published in 2024 - IPC A61B17/00 A61B17/16 A61B1/15 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to neurosurgery. After bone exposure, craniotomy is performed using a minimally invasive craniotomy device. Device is made in the form of a crown cutter with end teeth and a shank, interconnected by means of a limiter of the immersion of the crown cutter. Limiter is made in the form of a hexagonal plug interconnected with the cutter by means of a threaded connection and rigidly fixed on the shank. In the inner cavity of the shank there is a compression spring interconnected with a central sharpened rod, by means of which the device is fixed to the periosteum and the external plate. Using the medical brace, the drilling movement of the device is performed so that the central sharpened rod goes into the inner cavity of the shank, and the teeth of the crown cutter are immersed in the external bone plate with depth control by means of a threaded connection. End surface of the hexagonal plug is borne against the tissues of the head, preventing the cutter from falling into the cranial vault. Round bone section is drilled out. Dura mater is opened. After puncture of hematoma on cerebral cortex, encephalotomy is performed. Edges of the cerebral cortex are spread with a cerebral spatula in the direction of an intracerebral hematoma. That is followed by partial removal of the intracerebral hematoma by means of a surgical aspirator. After reduction of cerebral oedema under optical control of a surgical microscope, residual intracerebral hematoma is removed. Drainage is installed. Haemostatic sponge is placed in the cavity of the bone defect. Wound edges are closed in layers.

EFFECT: method enables increasing the effectiveness of the surgical intervention in minimally invasive removal of non-traumatic intracranial hematomas, reducing the length of the operation, reducing blood loss in the patient.
