Description
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to a novel craniocerebral Ommaya cyst puncture drainage fixing device.
Background
The Ommaya capsule is invented by a pakistan neurosurgeon in the continuous administration process of Ommaya in the ventricles of the lateral brain for treating fungal meningitis, and is called as a drug storage capsule, and is widely used for treating various central nervous system diseases.
The Ommaya bag is not communicated with the outside after being placed into a human body, the whole device is sealed under the scalp, and puncture liquid suction or continuous drainage through bag puncture can be performed at any time and for many times, so that the operation is simple and convenient, and the probability of retrograde infection can be obviously reduced. Compared with the traditional external ventricular drainage and ventricular-abdominal (V-P) shunt, the method has the advantages of small operation wound, short time, small chance of concurrent retrograde infection, capability of intracapsular administration and the like, and belongs to minimally invasive operation.
Ommaya capsules have a variety of uses, including the following:
1. Drug infusion: ommaya capsules are useful for infusion of drugs, in particular drugs for the treatment of brain diseases. By connecting a syringe or pump, the drug may be injected directly into the implanted capsular bag and delivered through a catheter to the diseased area of the brain.
2. Cerebrospinal fluid collection: ommaya vesicles may also be used to collect cerebrospinal fluid for analysis and monitoring at regular or as needed. By puncturing the capsular bag and connecting the sampler, cerebrospinal fluid in the capsular bag can be extracted to assess disease status, monitor therapeutic effects, or perform disease diagnosis.
3. Disease diagnosis and monitoring: the Ommaya capsule can puncture and aspirate liquid for multiple times, and through collection and analysis of cerebrospinal fluid, a doctor can obtain real-time information of brain diseases of a patient and monitor and evaluate the conditions of the brain diseases.
At present, as no drainage device matched with the Ommaya capsule is available, most of clinical use is common scalp needles for transfusion, and medical staff is often required to manually bend a puncture needle and then prick the needle into the Ommaya capsule for fixation, so that the puncture depth of the puncture needle is difficult to control, the occupational exposure risk of the medical staff is increased, and the problems that the needle is broken in the capsule or the lumen is narrow due to bending to lead to unsmooth drainage are easily caused; the external fixation of the puncture needle is very difficult and is not exact, and when the head of a patient moves, the puncture needle is easy to fall off or shift, and the puncture needle is often required to puncture again; once the scalp is shifted, an included angle is formed between the puncture needle and the scalp, direct compression is generated on the local scalp, the scalp is partially necrotized, and the infection risk is increased.
