Abstract

The invention discloses a multifunctional craniotome. The multifunctional craniotome comprises a shell, a motor is installed at one end of the shell, the output end of the motor is fixed to a rotary shaft, and a cutting knife fixedly sleeves one end of the rotary shaft; a support is arranged at the top of the shell and slidably connected with the shell, an adjusting block sleeves and is slidably connected to one end of the support, a telescopic rod is vertically fixed to the bottom of the adjusting block, and a fixed rod is installed at the other end of the support; a movable rod is inserted into the middle of the fixed rod, a touch plate is fixed to one end of the movable rod, a limiting block fixedly sleeves one end of the movable rod, and a spring is arranged at the outer side of the movable rod; one end of the spring is fixed to the limiting block, the other end of the spring is fixed to the inner wall of the fixed rod, a touch spot is installed at one end of the limiting block, and a switch is installed on the inner wall of the fixed rod. By means of the multifunctional craniotome, when the cutting knife approaches dura mater encephali, a user can be reminded to be careful, the efficiency of craniotomy is improved, and the cutting knife is prevented from damaging dura mater encephali.

Description

technical field [0001] The invention relates to the technical field of craniotomy devices, in particular to a multifunctional craniotomy device. Background technique [0002] The traditional craniotomy cannot control the cutting depth, and it is difficult to avoid damage to the dura mater when sawing the skull. It is very important to check brain injury and pathological changes without destroying the dura mater, and there is no warning device when the cutter is close to the dura mater, which affects the efficiency of craniotomy. Contents of the invention [0003] The object of the present invention is to propose a multifunctional craniotome in order to solve the shortcomings in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A multifunctional craniotomy, comprising a housing, a motor is installed at one end of the housing, the output end of the motor is fixed to a rotating shaft, a cut...
