Self-stopped electric bone drill with monitoring function

Abstract

The invention discloses a self-stopped electric bone drill with a monitoring function. The self-stopped electric bone drill comprises a main shell, a driving mechanism, a monitoring mechanism and a power supply mechanism, wherein the main shell is internally provided with the driving mechanism and the power supply mechanism; the driving mechanism is connected with the power supply mechanism; the monitoring mechanism is arranged at the upper end inside the main shell; the monitoring mechanism comprises a signal amplifier, a signal processor and a display; and the signal processor comprises an AD (analog to digital) converter and a control unit. The self-stopped electric bone drill is under micro-electric control depending on a sensor, the response time is faster, variation of torques, pressure and rotation speeds can be observed by a doctor through the display in the use process, then whether the bone drill already reaches an expected cutting position or not can be judged by the doctoraccording to data, and the security is high; and in addition, a mechanical structure space of a clamping end is released, and a common rapidly changed clamp can be used, so that the self-stopped electricbone drill can be adaptive to bone drills of more sizes and types when being compared with a conventional self-stopped electric bone drill, and is wide in application range.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a self-stop electric bone drill with a monitoring function. Background technique [0002] The medical electric bone drill can realize bone cutting in different parts through the change of the motor, drill bit and other components. The main purpose in the shell operation is to cut the bone to obtain the corresponding aperture. At present, the medical electric bone drill needs to stop automatically during the operation, mainly through the pressure lock. Tight spring structure, the spring is compressed by the axial pressure during the cutting process of the bone drill, so that the mechanical structure can be locked, once the axial pressure is lost through the cutting boundary, the spring rebounds to release the mechanical locking structure, making the bone drill lose its drive The self-stop function depends on the elastic force of the spring in the mechanical structure. If the el...
