Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a skull drill.
Background
The skull is located above the spinal column and consists of 23 flat bones and irregular bones with different shapes and sizes. The bones other than the mandible and hyoid bones are firmly connected to each other by means of sutures or cartilage, and function to protect and support the brain, sense organs, and the initial parts of the digestive and respiratory organs.
During neurosurgery procedures, operations often involving drilling holes in the skull bone margin are involved, such as: for the cases needing to suspend the dura mater really, such as after hematoma removal or tumor resection, drilling holes at the bone margin of the skull are needed, and the dura mater is suspended at the bone margin; for cases requiring a positive suspension of the temporal muscle, such as a temporal muscle application, skull bone margin drilling is required to provide a suture fixation site for the temporal muscle; some cases need suture to fix the artificial skull, such as children with small age, and hope that the skull can continue to grow and develop in the future.
In the traditional neurosurgery operation, manual operation is carried out to drill a skull target by using an electric ball grinding drill, and then water is added for cooling; because the manual operation error is large, the thickness of the skull of each person is different, particularly the thickness of the skull of a child is small, the drilling depth cannot be accurately controlled, and the situation that the dura mater and the brain tissue are injured by electric ball grinding drilling is easy to occur.
