Abstract
Bone drill is taken the utility model discloses a kind of broken bone, including bone drill and blocks set.Broken bone disclosed by the utility model takes bone drill, bone drill can during taking bone broken bone simultaneously, save the time；The storage that bone bits storage unit facilitates bone to consider to be worth doing；Spiral shape crumb loading portion is elastic component, compressible, and cooperation bone drill uses, and can be played a protective role in drilling, does not have to worry drilled too deep.This takes bone device compared with existing tooth-implanting operation takes bone drill, has easy to operate, and can realize that accurate positioning, drilling depth are controllable, can reduce the advantages of bone bits are lost.
Description
Technical field
The utility model relates to department of stomatology the field of medical instrument technology, in particular to a kind of broken bone takes bone drill.
Background technique
Tooth-implanting benefits " the third pair tooth " of defect of dentition patient because its beautiful, comfortable and good chewing effect becomes,
It is optimal reparation means after current anodontia.It is that dental implant is implanted to agomphosis position by way of surgical operation
Alveolar bone in, after it is in conjunction with alveolar bone, at an upper portion thereof installation repair artificial tooth.(such as periodontosis, alveolus for various reasons
Osteanabrosis etc.), there are the situations of the area Zhi Ya Alveolar bone insufficiency by many missing tooth patients, this can bring such as to dental implant surgical
The risks such as pain or planting body loosening after plant tooth.For this situation, it is necessary to carry out Bone Defect Repari, with guarantee dental implant surgical at
Function.
In clinic, bone renovating material mainly includes autologous bone, with (different) kind allograph bone, artificial synthesis bone etc..And autologous bone
With good biocompatibility, good skeletonization effect, it therefore is widely adopted.The source of autologous bone mainly includes plantation nest
Original position takes bone and dystopy to take bone.Original position take when bone because the cooling loss for considering bone to be worth doing of physiological saline in plantation nest preliminary process compared with
It is more, while the osteogenic activity of bone bits is also destroyed to a certain extent.What dystopy took that bone obtains is blocky bone, and size is larger, nothing
Method is repaired immediately, and currently used technology is blocky bone to be ground into short grained bone bits, then repaired.This method
It is complicated for operation, it is time-consuming, and will also result in the loss of osseous granules in process of lapping.
It is band saw dentation that the tooth-implanting operation of existing market, which takes bone drill mostly, and acquisition is ring-shaped blocky bone, later period
Also need to be ground into short grained bone bits, it is time-consuming bothersome.
Utility model content
Deficiency existing for bone drill is taken for current tooth-implanting operation, the utility model is intended to provide a kind of clever structure, behaviour
Make simplicity, that reduces bone bits loss takes bone drill with broken bone.
A kind of broken bone takes bone drill, including bone drill and blocks set, and the bone drill includes that the shank of strip and the bone of tubulose are considered to be worth doing
Storage unit, the tail end of the shank have connectivity port compatible with the dental handpiece of peripheral hardware, and head end is equipped with baffle ring, described
Shank is fixedly connected by baffle ring with the tail end that bone considers storage unit to be worth doing, and the head end of the bone bits storage unit, which has, cuts osteotome sword, described
It blocks set to be made of pipe tail portion, spiral shape crumb loading portion and tube head, spiral shape crumb loading portion is telescopic elastic component, institute
It states and blocks the outside for being socketed in bone drill and pipe tail portion is abutted with the baffle ring of bone drill, the tube head is equipped with for drilling portion and bone
The internal diameter of the nozzle that bits storage unit is pierced by, the nozzle is adapted with the outer diameter of bone bits storage unit, and is less than pipe tail portion and spiral
The internal diameter in shape crumb loading portion.
Bone bits storage unit described in the utility model includes the snap ring positioned at its tail end, and the snap ring is fixedly connected with baffle ring,
The snap ring and pipe tail portion are interference fitted.Further, the pipe tail portion is equipped with expansion slot.
The tube wall of bone bits storage unit described in the utility model is equipped with chip-removal hole.
Broken bone disclosed by the utility model takes bone drill, bone drill can during taking bone broken bone simultaneously, save the time；Bone bits
The storage that storage unit facilitates bone to consider to be worth doing；Spiral shape crumb loading portion be elastic component, it is compressible, cooperation bone drill use, can drilling when from
To protective effect, do not have to worry drilled too deep.This takes bone device compared with existing tooth-implanting operation takes bone drill, has operation letter
Just, and it can realize that accurate positioning, drilling depth is controllable, the advantages of bone bits are lost can be reduced.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the stereoscopic schematic diagram that the broken bone takes bone drill；
Fig. 2 is the stereoscopic schematic diagram for blocking set；
Fig. 3 is the use state diagram that the broken bone takes bone drill.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more preferably coupling structure.Each technology in the invention is special
Sign, can be with combination of interactions under the premise of not conflicting conflict.
As shown in Figures 1 to 3, a kind of broken bone takes bone drill, including bone drill and blocks set, and the bone drill includes the shank of strip
1 and the bone of tubulose consider storage unit to be worth doing, the tail end of the shank 1 has connectivity port compatible with the dental handpiece of peripheral hardware, first
