Intracranial hematoma is clear away sleeve pipe fixing device for art

Technical Field

The utility model relates to the technical field of medical equipment is relevant, concretely relates to intracranial hematoma is clear away sleeve pipe fixing device for art.

Background

Intracranial Hematoma removal (Removed Of intracrarial Hematoma) is less common in traumatic hematomas, accounting for about 10% Of Intracranial hematomas. Can be divided into a shallow part and a deep part. The former is a complex intracerebral hematoma, which often occurs with traumatic frontal and temporal contusion and laceration of the occipital region. Bleeding is usually caused by the expansion of hematoma into the brain, which is formed by the rupture of the cerebral cortical blood vessels, often accompanied by acute subdural hematoma. It is also seen in cases of depressed fractures. The latter is a simple intracerebral hematoma, which is caused by the rupture of deep blood vessels in the brain, and has no obvious injury or only slight contusion on the surface of the brain.

Intracranial hematoma removal procedures are applicable: clear diagnosis of CT with increased intracranial pressure or obvious focal symptoms. 2. Intracranial pressure is still high after subdural or epidural hematoma is removed, and the brain bulges outwards or the cerebral cortex has local contusion and palpation has fluctuation. 3. The hematoma is located in the deep part of the important functional area, and after the puncture and the suction, the hematoma is not reduced, and the intracranial pressure is not improved.

An endoscope sleeve is required to be adopted in clinical endoscopic craniocerebral hematoma removal operation, and the sleeve is fixed in the operation, which is a common problem. At present, medical workers hold the sleeve by hands by manpower, and half of the operation lasts for about 1 hour, so that the method for fixing the sleeve on the brain of a patient by the medical workers holding the sleeve by the hands is very high in requirement, and the personnel holding the sleeve by hands is difficult to be matched with the personnel performing the operation; in addition, a common flexible shaft retractor is adopted, so that the device has poor fixing effect, is easy to displace and even damages the brain of a patient; and an imported snake-shaped retractor is adopted, so that the scheme has higher cost, and a device fixedly connected with the sleeve is not provided, so that the popularization is difficult. In addition, the above common methods are difficult to operate when the angle position of the internal diameter sleeve needs to be finely adjusted in the operation.
