Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of minimally invasive dental device.
Background technique
Currently, application is lever mechanics principle in the extraction of clinical oral surgery, instrument used usually have dental elevator,
Chisel, hammer and dental forceps etc..Method is that dental elevator, chisel are placed at diastema and corresponding crest of alveolar ridge, firmly by tooth lever
Pine or chisel pine, then hold dental forceps, or rock or reverse lifting again, will suffer from tooth extraction.Using the extraction of above-mentioned instrument, there are many
Problem, first is that tooth extraction procedure relies primarily on the experience and technology of dentist, the clinic for needing to grow tempers grasp that could be more skilled very much,
Young doctor is difficult to grasp；Second is that above-mentioned instrument can not position on undesirable root, often very numb if encountering the root of the tooth of residual disconnected
It is tired, it is sometimes desirable to cut gum, bring many pains to patient；Third is that no matter being existed using dental elevator, chisel, hammer or dental forceps etc.
All wound area can be caused larger when pulling out the undesirable root of labial teeth, be influenced while bringing pain to patient beautiful；Therefore, it is necessary to seek
Seek a kind of minimally invasive instruments for tooth extraction.
Current minimally invasive extraction is to cut off periodontal ligament by using the wedging forces and slight rotary force of minimally invasive Exelcymosis knife
And alveolar bone crushing is squeezed simultaneously, then tooth can be extracted with dental forceps using micro- power, although this minimally invasive extraction means exist
The damage that periodontium is subject to by entire tooth extraction procedure greatly reduces, but due to using dental forceps to have tooth pulled out, still inevitably
The gum that patient can be touched causes different degrees of damage, brings many pains to patient, and minimally invasive instruments for tooth extraction is all
The expensive of import cannot be popularized, and there is no dedicated undesirable root puller currently on the market.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of minimally invasive dental device, the present invention is being pulled out
When tooth undesirable root, by canal pin being squeezed into the root canal of tooth undesirable root, and the pulling force generated by continuous rotating screw machine structure
It drives canal pin bindiny mechanism to pull canal pin, and then entire tooth undesirable root is pulled out.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of minimally invasive dental device, the minimally invasive dental device includes canal pin and pulls out root canal spike devices, described to pull out
Root canal spike devices include bracket and screw mechanism, and screw hole is provided on the bracket, and the screw mechanism runs through the screw hole；Institute
It states screw mechanism lower end and is provided with canal pin bindiny mechanism.
Minimally invasive dental device of the invention selects existing minimally invasive Exelcymosis knife to produce first when implementing in minimally invasive tooth extraction procedure
Raw wedging forces and rotary force, cutting periodontal ligament simultaneously squeeze alveolar bone crushing simultaneously, canal pin are then driven into tooth undesirable root
Root canal in, and the canal pin bindiny mechanism connected on screw mechanism is connected with canal pin, passes through constantly rotation branch upwards
Screw mechanism on frame and the pulling force generated pulls canal pin to extract undesirable root；Minimally invasive dental device provided by the invention is residual
The inside of root applies active force, not will cause the damage of the periodontium and gum around undesirable root；And in existing tooth pulling surgery
Dental forceps is then to apply active force around undesirable root, inevitably will cause patient's gum using dental forceps and is damaged, wound
It is big to hurt area, and easily cause the feared state of mind to patient.
In the present invention, the bracket that the bracket can have any shape provides as long as it can pull out canal pin for implementation
Fulcrum；Preferably, the bracket includes first support bar and second support bar, the first support bar and second described
One end of strut is connected by cross bar；The canal pin bindiny mechanism is arranged in the carrier openings side.
When being provided with aperture at the top of the canal pin for minimally invasive extraction, the canal pin bindiny mechanism be can be set to
The connection between canal pin can be realized by aperture by the drag hook of aperture, drag hook；In the present invention, the quantity of aperture can
Think it is multiple, as long as canal pin bindiny mechanism is enabled to closely to connect with canal pin；Preferably, the drag hook with it is described
It is to be detachably connected between screw mechanism；Using such setting, convenient for being dismantled and being sterilized to drag hook, it is also beneficial to for micro-
Create the collection of the device for pulling out canal pin of extraction；Preferably, the screw mechanism end is provided with annular groove, the drag hook
Including hook tail, coupler body and bill, in the annular groove of hook tail insertion screw mechanism end setting；Using such setting, lead to
It crosses and the hook tail of drag hook is embedded into annular groove, drag hook is prevented to be detached from screw mechanism, increase and connect between drag hook and screw mechanism
The tightness connect；It is further preferable that the hook tail is set as lantern ring compatible with annular groove, hook tail total is arranged
For lantern ring, lantern ring is embedded in the annular groove, the close connection between realization drag hook that can be more convenient and screw mechanism.
When the canal pin for minimally invasive extraction is common canal pin, when top is not provided with aperture, the canal pin
Bindiny mechanism can be set to clamping device, and clamping device realizes it between canal pin and clamping the top of canal pin
Connection；In the present invention, the clamping device can be that arbitrarily can be realized the mechanism of clamping canal pin, such as can be folder
Armed or clamping limb；Preferably, the clamping device includes driving lever, and Holding seat, the folder are fixed on the driving lever
