The application discloses a self-stopping skull drill in the technical field of brain surgery instruments, which includes a shell, a nut and a top plate. The nut is fixed on the inner wall of the shell through a connecting rod. There are pistons and driven discs, and a support rod is provided in the casing, the piston rod in the piston is fixed on the support rod, the piston is connected with the powder suction channel, the support rod is fixed with a motor, the output shaft of the motor is screwed with the nut, and the output shaft is fixed There is a rotating disc, a groove is arranged in the rotating disc, and a first air bag is arranged between the groove and the top plate; the top plate is engaged with the groove, and the bottom of the top plate is provided with a push rod, and the push rod is provided with a card slot; the inner wall of the shell is threaded A driven plate is connected, and a sleeve is fixed on the driven plate, and a block is arranged in the sleeve. A second air bag is provided at the bottom of the driven plate, and the second air bag communicates with the first air bag. A drill bit is provided at the bottom of the driven plate. This solution solves the problems that the existing electric drill cannot stop automatically and the bone powder flies everywhere.
Description
technical field [0001] The invention relates to the technical field of brain surgery instruments, in particular to a self-stopping skull drill. Background technique [0002] When medical personnel perform craniotomy with an electric drill, they often directly point the drill bit at the patient's skull to drill holes. According to past experience, medical personnel perform craniotomy and stop automatically, which cannot guarantee that the drill will reach a suitable position during the craniotomy. method, it is easy to cause high tension and physical fatigue of medical staff. During the craniotomy process of the traditional electric drill, it lacks the self-stop function, and when the drill bit is working, the bone powder generated during the cutting process will not only fly everywhere, but also the drill bit may work for a long time. It will lead to high temperature of the drill bit, damage to tissues such as the cerebral cortex, and cause secondary damage to the patient's ...
