Description
Technical field
The invention belongs to surgical operation medical apparatus technical field, more particularly to a kind of medical cranium brain to bore.
Background technology
When carrying out operation of opening cranium, generally to be drilled using drilling tool on hard skull.In use, need first to
Drill bit is installed on rig, and in the prior art, the connection of the two often uses helicitic texture by the connection of drill bit precession rig front end
Portion, this connected mode drill bit and rig in operative process are easily loosened, and the depth for causing to creep into skull is not known,
Easily cause operative failure, crisis patients ' lives safety, and dismount inconvenience.Rig using when can put cloth temporarily, only will
Drill bit is exposed, and easily stirs cloth into rig together during operation, inconvenient for operation.In addition in sphenotresia, it is necessary to set
Stopping means, to prevent drill bit after skull is penetrated, continue deeper into and damage brain tissue.Although this device can effectively avoid boring
The too deep entrance of head, but if deposited in operation between the position and skull of the failure of stopping means contingency or stopping means fixation
In deviation, it will cause to damage brain tissue, cause irreversible surgical consequences.The U of Patent No. CN 204293220 China is specially
Profit provides a kind of craniotomy drill drill bit, by setting the diameter of conductive bar to be more than the external diameter of bit head, to form hierarchic structure, from
And ensureing deviation be present in the case where other stopping means fail or between its position and skull, bit head is completely into skull
Conductive bar can be stuck on skull afterwards, avoid bit head from further deeply damaging brain tissue.But this structure simply prevents spacing
Failure of apparatus, itself can not play the effect, can not be used alone, still need to be used cooperatively with stereotactic surgery instrument.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is an object of the invention to provide a kind of medical cranium brain to bore, and drill bit can be with
It is used alone, it is not necessary to be used cooperatively, eliminate hidden existing for stopping means failure with the positioner of stereotactic surgery instrument
Suffer from, more securely and reliably；Drill bit is connected with rig by magnetic force, convenient disassembly, and in surgical procedure drill bit without departing from rig.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of medical cranium brain is bored, including drill bit and rig, it is characterised in that is also provided with including limiter, the limiter
Drill bit spacing hole, rig connecting rod, described drill bit one end is fixedly connected through the drill bit spacing hole with the limiter, described
The drill bit other end is fixedly connected with the rig connecting rod, and the chisel edge is provided with screw thread, and the rig front end is provided with irony
Drill bit connecting shaft, the irony drill bit connection axis center are provided with the groove matched with the rig connecting rod, set in the groove
There is magnet, the rig is externally provided with sterile bagging, and the sterile bagging is provided with elastic opening, and the elastic opening is located at the irony
At drill bit connecting shaft, the drill bit is located at the outside of the elastic opening.
The limiter includes rotary part and fixed component, and bearing one, the fixed part are provided with the rotary part
Bearing two, the rotary part and the fixed component are provided with part to be connected by the bearing one and the bearing two,
Size, shape identical through hole are respectively equipped with the middle part of the fixed component and the rotary part, described two through holes form institute
Drill bit spacing hole is stated, and center line is on the same line.
The diameter of the drill bit spacing hole is more than the external diameter of the drill bit, and less than the rig connecting rod cross section most
Big width.
The rotary part sidepiece is provided with fixing hole, the aperture direction of the fixing hole and the aperture of the drill bit spacing hole
Direction is vertical, and the drill bit is fixedly connected by the fixing hole, fixture with the rotary part.
The rotary part and the fixed component are cylinder, and the diameter of the rotary part is less than the fixation
The diameter of part.
The irony drill bit connecting shaft is hollow shaft sleeve.
The drill bit and the rig connecting rod are formed in one structure.
The beneficial effects of the invention are as follows：Drill bit is connected with rig by magnet, and installation and removal are convenient, instead of original
Threaded connection, the problem of loosening in the absence of drill bit in surgical procedure, ensure that being smoothed out for operation；Rig outer cover whether there is
Bacterium bagging, sterile bagging is provided with elastic opening, and just can expose drill bit, can not only play the mesh for preventing that rig from polluting
, and sterile bagging will not be stirred in bit operation into drill bit；Drill bit is provided with screw thread, can limit and pierce scalp
Depth；Drill bit is connected with limiter by fixing hole and fixture so that drill bit pierces depth adjustment；Pass through bearing one and axle
Two effect is held, realizes reach and spacing effect, rotary part can enter relative to fixed component after certain displacement is reached
Row idle running, position-limiting action can be played to drill bit, effectively prevent that the position on drill bit drilling head is too deep, so as to ensure that operation technique mistake
The safety of patient in journey；And the diameter of rotary part further increases the security of operation less than the diameter of fixed component, prevent
Encounter head periphery during spin-ended rotation member rotation；The limiter of the present invention and drill bit overall structure are simple in addition, low manufacture cost,
Operate easy to adjust, limiter and drill bit form an entirety, can be used alone, it is not necessary to determining for stereotactic surgery instrument
Position device is used cooperatively, and eliminates hidden danger existing for stopping means failure, more securely and reliably.
