Integral needling-drilling encephalic hematoma puncture drainage device

Abstract

The invention discloses an integral needling-drilling encephalic hematoma puncture drainage device. The integral needling-drilling encephalic hematoma puncture drainage device is characterized by comprising a T-joint, a drilling body, a limiting device, a cleaning rod, a drainage tube, a liquid inlet needle-shaped channel and a drilling sleeve of which a perforated cap limiter sleeves the T-joint,wherein the drilling body is inserted into the drilling sleeve of the T joint, and is fixed in cooperation with a groove in the drilling body sleeve through a lug I on the side face of the T-joint. The integral needling-drilling encephalic hematoma puncture drainage device has the beneficial effects that: a self-destruction function can be realized after the completion of skull drilling, so thatthe integral needling-drilling encephalic hematoma puncture drainage device cannot be reused from the structure, the effect of operation be affected by the pollution of a drill bit is avoided; moreover, liquid hematoma can be sucked and drained; saline is injected into a hematoma cavity through the drainage tube on a perforated cap in order to dilute and drain viscous hematoma; a hematoma liquefaction agent is injected into the remaining solid hematoma through an injection needle device channel until intracranial hematoma is removed.

Description

technical field [0001] The invention relates to a medical device, in particular to a needle-drill integrated puncture and drainage device for intracranial hematoma. Background technique [0002] The intracranial pressure (ICP) of the human body needs to be kept within a certain value. The normal ICP is 0.667-2Kpa or 5-15mmHg. If it is too high or too low, people will feel headache, vomiting, papilledema, disturbance of consciousness, and changes in vital signs. Even the lesions of brain herniation. When traumatic brain injury or intracerebral lesions occur in the human body, blood or fluid will accumulate in the brain, often accompanied by intracranial pressure deviation from normal. At this time, extracranial or lesion drainage must be performed through surgery to relieve symptoms and treat . Craniocerebral drainage is often used in operations on cerebral hemorrhage, hydrocephalus, and brain tumors in modern medicine. Cranial drainage can reduce intracranial pressure, dra...

AI Technical Summary

Problems solved by technology

[0003] In clinical nursing, empty infusion bottles are sterilized and then inserted into blood transfusion sets to make a simple cranial drainage device. Such a drainage device is cumbersome to make manually, and the disinfection requirements of each link are relatively high, otherwise it is easy to cause infection and low safety. The drainage effect is not good; when intracranial injection of drugs such as hemolytic agents or antibiotics is required, it is complicated to pull out from the joint, and it is easy to cause intracranial infection, endangering the life safety of patients
