Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of medical appliances, in particular to a head fixing device for intracranial hematoma minimally invasive 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 are left with functional disorders; adult cerebral hemorrhage 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. In the past, a 3D-slicer software positioning method is mostly adopted in the minimally invasive hematoma drainage method under the guidance of CT, the method simulates the hematoma condition of a patient on a mobile phone for positioning, but in actual operation, the patient needs to be switched to, the line needs to be drawn again for positioning, and the accuracy is low. 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, the accuracy of puncturing is not high for the physicians with many years of clinical experience, and the beginners are lower. Because the head position of a patient is not fixed, the standard aspect of CT scanning is inaccurate, the scanning result of each CT scanning is inconsistent, the puncture plane is difficult to accurately determine, and even if the puncture plane is determined, if the plane cannot be vertical to the surface (horizontal plane) of an operation bed, a pipeline can be deviated to the skull base or the skull top in the process of puncture tube placement, the tube placement accuracy is also low, each tube placement is a new tube replacement process, multiple punctures cause fatigue of operators, assistants and CT technicians, the risk of hemorrhage of the patient is increased, and the family members are not trusted.
At present, although there are some head fixators, such as chinese utility model CN 209751235U, a head fixation clamp for neurosurgery, its movable plate can only be lifted up and down, i.e. only can be adjusted in height, but not in forward, backward or side-tipping adjustment, and only lifting up or down adjustment cannot adjust the head of the patient in intracranial hematoma puncture so that the head of the patient passes through the plane of the crystalline lens and the external auditory canal and is perpendicular to the horizontal plane, thus it is not applicable.
