Description
Technical field
The present invention relates to a kind of bone drilling device with accurate scale and its application, belong to technical field of medical instruments.
Background technology
When carrying out Parkinson treatment using DBS (lesions located in deep brain) operations, it is necessary to carry out perforate in brain, adopt at present
When the mode taken is mainly with hand feed to carry out head drilling, and judge whether situation about drilling, doctor is always needed according to brill
Drill bit feedback force and feel after wearing judge.If there is doctor's error in judgement or experience shortage, it is possible to cause to bore
Head depth enter it is too deep injure its hetero-organization, cause the situation of secondary injury to occur.
Human brain construction includes hair, scalp, skull, meninx and brain tissue.Scalp plays covering, and skull mainly plays protection
Effect, and skull bottom is meninx, meninx is flexible, there is nearly 2mm gap between general human skull and meninx, on head
The necessary spiritual high concentration of the Shi doctor that drills, to prevent continuing to feed after skull is drilled, injures meninx and brain tissue.
Therefore, need a kind of bone drilling device of design badly, half step distance feeding can be carried out when also not drilling skull, even if ensureing
Still there is larger surplus after drilling skull, do not injure other brain tissues.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of bone drilling device with accurate scale, is filled using the bone drill
Putting can ensure under the feeding state of half step distance, even if drilling skull, drill bit still has larger surplus between meninx, will not hinder
And other brain tissues, protection patient medical safety.
The present invention also provides a kind of operating method of above-mentioned bone drilling device with accurate scale.
Technical scheme is as follows：
A kind of bone drilling device with accurate scale, including outer shell barrel, drill bit and sliding block, cunning is offered in the outer shell barrel
Groove and the multiple locking slots communicated with chute, the side of locking slot are provided with accurate scale, and drill bit is placed in outer shell barrel, sliding block edge
Chute moves through locking slot positioning, and it is spacing deep to adjust the feeding of drill bit that drill bit moves through sliding block in outer shell barrel
Degree.
Preferably, the drill bit afterbody is provided with retaining ring.This design is advantageous in that, stretches out outer shell barrel when promoting drill bit
When, sliding block stops retaining ring so that drill bit stops stretching, the exact depth of guarantee drill bit feeding.
Preferably, the sliding block includes pole and the head being connected, and head is located on the outside of chute and head width is more than
Trough width, pole through chute and with chute CONTACT WITH FRICTION.This design is advantageous in that user adjusts by promoting head
Movement of the whole sliding block in chute is saved, pole can avoid excessive slip with chute CONTACT WITH FRICTION, and sliding block is effectively ensured and reaches phase
Groove location should be locked.
Preferably, the bottom end opening of the chute, top closure.This design is advantageous in that the chute of one end open is square
Just the pole of sliding block enters in chute.
Preferably, the maximum feeding depth of the drill bit is 5mm.
Preferably, the multiple locking slot is correspondingly arranged at following accurate scale：1mm、2mm、2.3mm、2.6mm、
2.9mm、3mm、3.1mm、3.2mm、3.3mm、3.4mm、3.5mm、3.6mm、3.7mm、3.8mm、3.9mm、4mm、4.1mm、
4.2mm、4.3mm、4.4mm、4.5mm、4.6mm、4.7mm、4.8mm、4.9mm、5mm。
A kind of operating method of the bone drilling device with accurate scale, comprises the following steps：
The first step：The locking slot according to corresponding to patient's head thickness of scanning gained screws in sliding block；
Second step：Brill bone is carried out, promotes drill bit afterbody drill bit is progressively stretched out outer shell barrel, when feeding depth reaches locking slot
During the depth of setting, retaining ring encounters sliding block, prevents drill bit from further feeding；
3rd step：If being not reaching to the situation for drilling skull, sliding block is carried out downwards to minute movement and screwed in corresponding
Locking slot, drill bit is promoted to stretch out again, until drilling skull.
The beneficial effects of the present invention are：
Bone drilling device smart structural design of the present invention, it is simple to operate, it is easy to use, it can be ensured using the bone drilling device
Under the feeding state of half step distance, even if drilling skull, drill bit still has larger surplus between meninx, will not injure other brain groups
Knit, greatly protect patient medical safe.It acts on obvious, significant effect, is worthy of popularization.

Embodiment
The present invention will be further described by way of example and in conjunction with the accompanying drawings, but not limited to this.
Embodiment 1：
As shown in Figure 1 to Figure 3, the present embodiment provides a kind of bone drilling device with accurate scale, including outer shell barrel 1, brill
First 2 and sliding block 4, chute 5 is offered in outer shell barrel 1 and the multiple locking slots 6 communicated with chute 5, the side of locking slot 6 are provided with
Accurate scale, drill bit 2 are placed in outer shell barrel 1, and sliding block 4 moves through locking slot 6 along chute 5 and positioned, and drill bit 2 is in outer shell barrel 1
Inside move through that sliding block 4 is spacing to adjust the feeding depth of drill bit 2.
Sliding block 4 includes pole 402 and head 401, and pole 402 is welded with head 401, head 401 be located at the outside of chute 5 and
The width of head 401 is more than the width of chute 5, and pole 402 is in chute 5 and support 402 and the CONTACT WITH FRICTION of chute 5, the present embodiment
Rubber sleeve is covered on pole 402, the frictional force of pole 402 and chute 5 can be increased.User is by promoting head 401 to adjust
Movement of the whole sliding block 4 in chute 5 is saved, pole 402 can avoid excessive slip with the CONTACT WITH FRICTION of chute 5, sliding block 4 is effectively ensured
Reach the corresponding position of locking slot 6.
The afterbody of drill bit 2 is provided with retaining ring 3, and retaining ring 3 and drill bit 2 are formed in one structure.Outer shell barrel 1 is both ends open
Structure, drill bit 2 are placed in outer shell barrel 1, and (frictional force is enough to ensure that under plumbness retaining ring 3 with the inwall CONTACT WITH FRICTION of outer shell barrel 1
Drill bit will not glide in outer shell barrel), when promoting drill bit 2 to stretch out outer shell barrel 1, sliding block 4 stops retaining ring 3 so that drill bit 2
Stop stretching out, ensure the exact depth that drill bit 2 is fed.
