Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a free-standing pillow for the back of the head of a patient after a craniotomy. Background Art

[0002] Surgery is abbreviated as operation, commonly known as opening the door, which refers to the process of entering the human body or other biological tissues through surgical equipment or surgical instruments under the operation of surgeons or other professionals to eliminate lesions, change structures or implant foreign objects by external means.

[0003] Neurosurgery is a branch of surgery. It is a high-level discipline that uses unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, and its related ancillary structures, such as the skull, scalp, cerebral blood vessels and meninges, as well as injuries, inflammation, tumors, malformations and certain genetic metabolic disorders or functional disorders, such as epilepsy, Parkinson's disease, neuralgia and other diseases, and explores new diagnosis, treatment and prevention technologies.

[0004] In neurosurgery, craniotomy is considered a major operation and is generally performed with caution due to its high risk. However, it is still necessary to perform craniotomy for some special diseases, such as Parkinson's disease and epilepsy.

[0005] However, clinically, many neurosurgery patients have lesions in the cerebellum. After craniotomy, the incision is made in the occipital region. When the patient lies flat, the area under pressure is in the occipital region. For awake patients, the incision is compressed, causing pain and discomfort, and they cannot lie flat. For comatose patients, the incision is compressed, causing local ischemia and hypoxia, which can easily cause poor healing of the incision. Some patients have long-term pressure on the occipital region, which can easily cause pressure injury. Therefore, a pillow is designed to lift the occipital region of patients after craniotomy to change the above technical defects. Utility Model Content
