Technical parameters and cleaning standards for medical hollow drillsRelease date:2024-08-15

Medical hollow drills are mainly used for grinding bones. They have a strong and accurate structure, low consumption, are designed based on ergonomics, and are easy to operate. Its standard name is multi blade steel plate drill bit, which adopts the form of multi blade annular cutting. The drill bit only cuts the outer diameter annular part of the hole and does not cut the middle part, greatly improving the perforation efficiency. In addition, by combining with the magnet drill bit, it can carry out the piercing operation at any time on the site.

Avoid damaging the air hole. Carefully handle lesions infiltrating the skull and bone markers hidden outside the dura mater. When using an end mill for operation, it is important to avoid transmitting the vibration of the end mill to the brain tissue (which can cause contusions and subarachnoid hemorrhage). It is also necessary to avoid forcefully opening the inner plate and inserting the drill into the dura mater and brain tissue, which may cause cortical damage.
