Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a water flushing, suction and visualization device for anterior cervical ACDF surgery. Background Art

[0002] In the ACDF surgery of the anterior cervical spine, the spinal endoscope is now added for visual operation in conjunction with the application of traditional cervical spine surgical instruments. Due to the injection of physiological saline and the magnification of the visual field, the ACDF surgery can reduce bleeding, be more accurate and safer. However, there is no corresponding supporting instrument for this method at present. The water injection process is not scientific enough, and the water pressure in the intervertebral space cannot be properly controlled to achieve the purpose of further controlling and reducing bleeding, clearer visual field, easier operation and safer operation. The existing water injection process is open and completed by assistants, which interferes with the surgeon's operation in the surgical area and overflows around the injection, causing water accumulation and contamination of the surrounding tissues. It takes time to install the spinal endoscope, and the installation and connection of various interfaces increase the chance of infection. The decompression process in the anterior cervical spine surgery will directly expose the spinal cord. When the spinal endoscope and instruments are used, there is no limit on the insertion distance. When the surgeon is accidentally hit by the surrounding personnel, there is a potential risk of spinal cord injury. Utility Model Content
