Head fixing device for intracranial hematoma minimally invasive puncture

Abstract

The invention belongs to the technical field of medical appliances, and specifically discloses a head fixing device for intracranial hematoma minimally invasive puncture. The fixing device comprises asupporting base and two head fixators erected on the supporting base, the supporting base comprises a bottom plate, a lifting and tilting mechanism and a movable plate, the lifting and tilting mechanism is installed between the bottom plate and the movable plate to adjust the lifting, forward tilting, backward tilting or side tilting of the movable plate, the head fixator comprises a fixing plate, both ends of the fixing plate are connected with the upper end of a fixing rod, the lower ends of the fixing rods are both connected with a fixing clip, and the two fixing clips are respectively detachably connected with the edge of the movable plate. The height of the head of a patient can be adjusted by the device, the adjustment of forward tilting, backward tilting and side tilting can also be realized, the head of the patient can also be effectively fixed, so that the puncture plane of the patient can be stable and vertical to the horizontal plane, and then the accuracy of intracranial hematoma minimally invasive puncture is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of medical appliances, in particular to a head fixation device for minimally invasive puncture of intracranial hematoma. 【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 more than 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 induce rebleeding...

Problems solved by technology

However, the accuracy of puncture is not high for doctors with many years of clinical experience, and it is even lower for beginners.

Because the position of the patient's head is not fixed, the standard level of CT scan is not accurate, resulting in inconsistent results of each CT scan, and it is difficult to accurately determine the puncture plane. Even if the puncture plane is determined, if the plane is not perpendicular to the operating table (horizontal plane) , during the process of puncture and catheterization, the pipeline will be biased towards the skull base or the top of the skull, which will also cause low accuracy of catheter placement, and each catheter placement is a new process of re-cannulation. Multiple punctures make the operator, assistant, CT technicians are fatigued, which increases the risk of rebleeding for patients, and family members do not trust them, etc.

[0004] And at present, though also have some head holders, such as Chinese utility model patent CN 209751235 U a kind of neurosurgery head holder, its movable plate can only lift up and down, that is, it can only adjust the height, and can not lean forward or backward. Tilt or roll adjustment, but only raising or lowering adjustment can not adjust the patient's head in intracranial hematoma puncture so that the plane of the patient's head passing through the lens and external auditory canal is perpendicular to the horizontal plane, so it cannot be applied
