Description
Technical Field
The invention relates to the field of operating tables, in particular to a multi-body-position neurosurgery operating table.
Background
Neurosurgery is a discipline for treating diseases of brain, spinal cord and peripheral nervous system by using a surgical method and taking an operation as a main treatment means, is a discipline of high, essence and pointedness in the current medical field, and is generally recognized as the field with the highest medical position; the operations of tumor, blood vessel, disc discectomy and the like in neurosurgery are microsurgery operations performed under a large-scale operation microscope, the operations are extremely fine, complex, dangerous and time-consuming, not only medical staff are required to have better technique and physical strength, but also great challenges are brought to patients; in the operation process, patients are in an anesthesia state, and in the anesthesia state, the patients are in a passive lying position, but a large neurosurgery operation usually needs several hours or even more than ten hours, so that the patients need to face a very troublesome problem, namely pressure injury.
Pressure injury is localized damage to the skin or underlying tissues, usually occurring in the bony prominences or in areas of prolonged compression, and can be manifested by local tissue damage but complete or open ulceration of the epidermis, with pain, and most of the pressure injuries suffered by patients during surgery exhibit symptoms of injury 1-3 days after surgery; during the operation, the pressure injury is positively correlated with the operation time, the patient can have irreversible injury after keeping an operation position for more than 2 hours, the occurrence rate of the pressure injury is increased by 33 percent every 30 minutes, and the pressure injury can be inevitably generated after the pressure injury lasts for 4 hours; under the prior art condition, for the prevention patient pressure nature damage appears, need adopt multiple silica gel cushion to carry out static bedding to patient different positions, cushion kind quantity is tens of even, not only complex operation, and the pressure nature damage of different degrees can appear equally in cushion pressure cushion for a long time, consequently, research and development one kind is applied to the neurosurgery and can avoid the patient to appear pressure nature damage's operation table has obvious meaning.
