Description
Technical field
The invention belongs to brain section medical instruments field, more particularly to a kind of brain milling is bored.
Background technology
As the progress and development of medical science, Cerebral surgery are increasingly common.Cerebral surgery is the high operation of required precision,
Once occurring a little slipping up in brain surgery, serious sequelae, such as the symptom such as dizziness, homonymous hemianopia will be brought.One people
Brain there are about 100,000,000,000 neurons, there are about trillions of Synaptic junctions between neuron, form network mazy
Connection, each neuron includes millions of protein, performs different functions, and with age, quantity is successively decreased, therefore
Requirement of the cerebral operationses for medical apparatus is very high, and particularly brain milling is bored, to its transmission accuracy and robust motion requirement
It is very high.Brain milling brill internal structure in the market for medical treatment is various, and transmission mechanism species is also a lot, but all passes mostly
Dynamic low precision, bumpy motion, noise, vibrations are big, and complicated and cutter changing is inconvenient.
The content of the invention
The shortcomings that it is an object of the invention to overcome prior art, there is provided a kind of brain milling is bored, and its transmission mechanism ensures coaxially
Transmission, the generation of noise and vibration is reduced, and use straight spur gear group, increase power improves transmission accuracy simultaneously.
To solve the above problems, the present invention provides the first technical scheme：A kind of brain milling is bored, including transmission mechanism, is arranged on
The cutter changing mechanism of transmission mechanism one end, the brain milling head fender bracket replacing mechanism for being arranged on cutter changing mechanism one end；It is described
