The utility model relates to the technical field of medical appliances, in particular to puncture positioning system and three-dimensional accurate locator for intracranial hematoma minimal access puncture.
[ background of the invention ]
The cerebral apoplexy is the first cause of death of human beings at present, and is characterized by high morbidity, high mortality and high disability rate, wherein the morbidity of cerebral hemorrhage is 60-80 people/10 ten thousand per year, the cerebral hemorrhage accounts for about 20-30% of all cerebral apoplexy in China, the mortality rate in the acute stage is as high as 30-40%, and more than 30% of survivors leave functional disorders; the cerebral hemorrhage of adults in Europe and America accounts for 10% -20% of all cerebral apoplexy, and the fatality rate is 23% -52%.
Based on the limitations of large trauma and high risk of cerebral hemorrhage patients and the rapid reduction of local pressure to induce rebleeding or aggravation of edema in the craniotomy, the minimally invasive hematoma drainage method increasingly pays more attention to and is applied to the clinic. The minimally invasive hematoma drainage method generally adopts a line drawing method, an aiming method and the like to perform puncture according to the principle nearby, the puncture direction is inaccurate, the depth of a drainage tube cannot be changed, the puncture drainage is mainly performed in a local small range, hematoma is not thoroughly cleared, and furthermore, the puncture of a brainstem, a third ventricle and a fourth ventricle is dared to be performed and the puncture of a longer drainage tube is not required. Based on this, the improved soft channel stereotaxic technique is widely applied to the minimally invasive hematoma drainage method, and the technique needs the soft channel drainage tube to enter the intracranial for a long distance (about 12cm is needed for the hemorrhage in the basal ganglia region), needs accurate positioning, particularly needs accurate positioning for the drainage of the third ventricle, the fourth ventricle and the brainstem, and does not allow multiple times of puncture, otherwise, the injury is large, the effect is poor, particularly, the brainstem puncture does not allow failure. However, many years of clinical experience shows that the puncture accuracy is not high, and beginners are lower.
