Abstract

The invention provides a precise stereoscopic positioner for minimally invasive paracentesis of intracranial hematoma. The precise stereoscopic positioner comprises a positioning device and a positioning belt. The positioning device comprises a support, a sliding part and a reference rod, the support comprises a top plate, a bottom plate and a connecting plate connecting the bottom plate and the top plate, the top plate and the bottom plate are arranged oppositely, and the top plate is provided with a sliding hole and an angle positioning scale line; the bottom plate is provided with three first reference rod positioning holes along the sliding hole and three first drainage tube positioning holes corresponding to the three first reference rod positioning holes. The sliding part is mountedon the top plate through a bolt and is provided with a second reference rod positioning hole and a second drainage tube positioning hole at an interval, one end of each reference rod is inserted intothe corresponding first reference rod positioning hole, the reference rod penetrates the sliding hole and the second reference rod positioning hole, and the positioning belt is mounted on the support.The precision stereoscopic positioner is capable of improving puncturing accuracy of the minimally invasive paracentesis of intracranial hematoma. The invention further provides a puncture positioning system for minimally invasive paracentesis of the intracranial hematoma.

Description

technical field [0001] The invention relates to a positioning device, in particular to a puncture positioning system for minimally invasive puncture of intracranial hematoma and a precise stereotaxic device thereof. Background technique [0002] Stroke is currently the number one cause of human death, characterized by high morbidity, high mortality, and high disability rate. Among them, the incidence of cerebral hemorrhage is (60-80) per 100,000 people per year, accounting for about 100,000 in my country. 20% to 30% of all strokes, the fatality rate in the acute phase is as high as 30% to 40%, and >30% of the survivors have residual dysfunction; adult cerebral hemorrhage in European and American countries accounts for 10% to 20% of all strokes, and the mortality rate is as high as 30% to 40%. 23% to 52%. [0003] Based on the limitations of surgical craniotomy on patients with cerebral hemorrhage due to its large trauma, high risk, and rapid reduction of local pressure to ...
