The use of craniotomy drill is a basic operation in brain surgery, and timely completion of this operation can obviously improve surgical efficiency. The operation process is simple and clear, but there are also certain risks involved. The most important thing is that the surgeon should be familiar with these relatively basic surgical steps to minimize the incidence of complications.

The skull consists of an inner plate and an outer plate separated by wooden barriers. This anatomical relationship is particularly important when using a craniotomy drill. Surgeons can quickly and safely perforate the skull's outer and inner plates, but when perforating the inner plate, in order to avoid the vibration of the craniotomy drill directly affecting the dura mater and cerebral cortex, the movements must be soft. When performing craniotomy in the posterior cranial fossa, be careful when using a milling cutter to enter the foramen magnum and remove the skull where the transverse sinus and sinus converge. The surgeon must hold the skull drill handle with a pen in their right hand and stabilize their arm on their hand. When using a high-speed craniotomy drill, the following points should also be noted:

When using a high-speed craniotomy drill, remove the gauze and cotton swabs around the drill in advance. When the drill rotates, it may become entangled in the drill, causing braided damage and avoiding damage to the underlying brain tissue. Especially during deep surgery, attention should be paid.

2. The rotating craniotomy drill may slide away from its original direction, especially when rotating at low speeds or when the drill is sluggish. In this case, pressing hard can easily cause the craniotomy drill to be misaligned. To prevent this situation, the motor must be turned on and the steering wheel must be held before the craniotomy drill comes into contact with the skull.

3. Do not use a craniotomy drill to drill vertically downwards at the front end, maintain the angle. When drilling in adjacent soft tissue areas, the diamond craniotomy drill must be replaced to avoid damaging the soft tissue. 5. When using a high-speed cranial drill, a large amount of heat must be generated to keep the water flowing towards the drilling area. High speed cranial drill is a difficult tool for neurosurgeons, and practicing its operation in the laboratory is important to familiarize oneself with its performance and understand its scope of application. Untrained doctors cannot fully utilize the role of high-speed drilling during surgery, which affects the safety of the operation.

The above is an introduction to 5 precautions when using a high-speed craniotomy drill. Thank you for reading.
