Requirements and steps for using gypsum sawsRelease date:2024-08-15
Only trained personnel are allowed to use gypsum saws. If sharp serrations are used, the heating of blunt serrations will accelerate. Rotating blades. Due to the fact that vibration is generated by hard materials, serrations may generate heat and cause tissue burns. By using sharp serrations or gently rotating the serrations each time they are cut, and continuing with the remaining part of the serrations, the heat generated by the serrations can be effectively reduced.

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. Compared with the ordinary Fried Dough Twists drill, it is more efficient and easier to cut.

Basic principles of using a craniotomy drillRelease date:2024-08-15
The basic principle of crossing the midline for craniotomy. A small bone flap that crosses the midline for craniotomy. Crossing the sinus opening can be done in different ways. To ensure sufficient exposure and avoid damage to the venous sinus, it is recommended to adhere to the following principle: in small (sagittal sinus, sagittal position less than 5cm) bone flap craniotomy, 2 bone holes and 1 paranasal bone hole can be perforated in the sinus. The skull starts from the lateral foramen and stops about 1.5cm beside the sinus. Then cut the bone outward from the sinus foramen and merge it with the outer bone seam.

Precautions for craniotomy drill during drilling operationRelease date:2024-08-15
Special attention should be paid to the protection of the venous sinus located above the dura mater when using a craniotomy drill. Pay attention to the integrity of the dura mater. 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.
