Abstract

The invention relates to a multifunctional trephine. The multifunctional trephine is characterized by comprising a host and a drill bit; the host comprises a battery clamping groove, a battery, a handle, a motor, a lighting lamp, a switch fuse, a heat dissipating hole, a motor, a drill bit connecting clamping groove base, a clutch and a sensor; the drill bit connecting clamping groove base is arranged at the head end of the host, the drill bit is detachably connected with the drill bit connecting clamping groove base, the battery clamping groove is formed in the bottom end of the host, the battery is arranged in the battery clamping groove, the lighting lamp is installed at the front end of the handle, the switch fuse is arranged at the position, easy to operate, of the handle, the motor is arranged in the host, the heat dissipating hole corresponds to the motor in position, the clutch is arranged in the drill bit connecting clamping groove base, the drill bit is connected with the clutch device, and the sensor is arranged on the drill bit and connected with the motor in a linkage mode. When the drill bit drills through the bone, the sensor detects the changes of rotating speed and torque of the drill bit to be in linkage with the motor so that the motor can stop working and force the drill bit to stop rotating.

Description

[0001] 【Technical Field】 [0002] The invention relates to a medical instrument used for craniocerebral surgery, in particular to a multifunctional cranial drill used for drilling and performing operations such as ventricular catheter or hematoma cavity catheterization, drainage, and flushing. [0003] 【Background technique】 [0004] Hypertensive intracerebral hemorrhage (HICH) is a disease with a very high mortality rate. In recent years, the number of cases has been on the rise, and the age of onset is getting younger and younger. Not only the fatality rate is high, but also the disability rate ranks first among all stroke types. The treatment methods and therapeutic effects of cerebral hemorrhage larger than 30ml above the tentorium and 10ml below the tentorium have always been an important topic of neurosurgery research. Such as decompression of large bone flaps, large bone windows, small bone windows, and recent microsurgery, endoscopic surgery can remove intracranial hematoma ...
