Abstract
The invention relates to a device for removal of a root canal nail. The device for removal of the root canal nail comprises a rack and a screw mechanism; the rack is provided with a screw hole; the screw mechanism penetrates through the screw hole; and the lower end of the screw mechanism is provided with a root canal nail connecting mechanism. In the implementation course of minimally invasive tooth extraction, the root canal nail is inserted into the root canal of a residual root to closely connect the root canal nail connecting mechanism and the root canal nail; and the tension produced by continuous rotation of the screw mechanism drives a drag hook to pull the root canal nail, so as to remove the root canal nail and extract the whole residual root.
Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to a kind of device pulling out canal pin.
Background technology
At present, when clinical oral surgery is had tooth pulled out, application be lever mechanics principle, apparatus used has dental elevator, chisel, hammer and dental forceps etc. usually.Method, for dental elevator, chisel are placed in diastema and corresponding alveolar ridge crest place, firmly by tooth lever pine or cutter pine, and then are held dental forceps, or is rocked or reverse lift, pulled out by trouble tooth.Adopt above-mentioned apparatus to have tooth pulled out and there are problems, one is experience and the technology that tooth extraction procedure mainly relies on dentist, need to grow very much clinical temper could be more skilled grasp, young doctor is difficult to grasp; Two is that above-mentioned apparatus cannot be located on undesirable root if run into residual disconnected root of the tooth, often pretty troublesome, sometimes needs to cut gingiva, brings a lot of misery to patient; Three is adopt dental elevator, chisel, hammer or dental forceps etc. that wound area all can be caused comparatively large when pulling out the undesirable root of labial teeth, affects attractive in appearance to patient while bringing misery; Therefore, need to seek a kind of Wicresoft instruments for tooth extraction.
Current Wicresoft's exodontia is mainly cut off periodontal ligament by the wedging forces and slight revolving force using Wicresoft's Exelcymosis knife and is extruded alveolar bone simultaneously and increases gap, then micro-power is used tooth can be extracted with dental forceps, although the damage that periodontal tissue is subject at whole tooth extraction procedure by this Wicresoft exodontia means reduces greatly, but owing to using dental forceps exodontia, still inevitably touch the gingiva of patient, cause damage in various degree, a lot of misery is brought to patient, and Wicresoft's instruments for tooth extraction is all import, expensively can not to popularize, there is no special undesirable root tool for uprooting in the market.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of device pulling out canal pin is provided, when pulling out canal pin, by canal pin being squeezed in the root pipe of tooth undesirable root, by compact siro spinning technology between canal pin bindiny mechanism and canal pin, and drive drag hook to pull canal pin by the pulling force that continuous rotating screw mechanism produces, thus pull out canal pin, whole undesirable root is pulled out.
For achieving the above object, the present invention adopts following technical scheme:
Pull out a device for canal pin, described in pull out canal pin device and comprise support and screw mechanism, described support is provided with screw, and described screw mechanism runs through described screw; Described screw mechanism lower end is provided with canal pin bindiny mechanism.
In the present invention, when implementing Wicresoft's exodontia, first the wedging forces selecting existing Wicresoft Exelcymosis knife to produce and revolving force, cut off periodontal ligament and extrude alveolar bone simultaneously and increase gap, then the canal pin suitable with the device pulling out canal pin is driven in the root pipe of undesirable root, completes being fixedly connected with of canal pin and undesirable root; Then support both sides are resisted against on the adjacent teeth on both sides of undesirable root to be pulled out, and the canal pin bindiny mechanism that screw mechanism one end is arranged and described canal pin compact siro spinning technology, the pulling force produced by constantly rotating up screw mechanism pulls canal pin to be extracted by undesirable root.
In the present invention, the support that described support can have any shape, as long as it can provide fulcrum for implementing to pull out canal pin; Preferably, described support comprises the first support bar and the second support bar, and described first support bar is connected by cross bar with one end of described second support bar; Described canal pin bindiny mechanism is arranged on described carrier openings side.
When the top of the canal pin of having tooth pulled out for Wicresoft is provided with aperture, described canal pin bindiny mechanism can be set to can by the drag hook of aperture, and drag hook realizes the connection between canal pin by aperture; In the present invention, the quantity of aperture can be multiple, as long as can make canal pin bindiny mechanism and canal pin compact siro spinning technology; Preferably, between described drag hook and described screw mechanism for removably connecting; Adopt this kind to arrange, be convenient to dismantle drag hook and sterilize, be also conducive to the collection of the device pulling out canal pin; Preferably, described screw mechanism end is provided with annular groove, and described drag hook comprises hook tail, coupler body and bill, and described hook tail embeds in the annular groove of screw mechanism end setting; Adopt this kind to arrange, by the hook tail of drag hook is embedded in annular groove, prevents drag hook from departing from screw mechanism, increase drag hook and the compactness be connected between screw mechanism; More preferably, described hook tail is set to the collar suitable with annular groove, and hook tail total is set to the collar, and the collar embeds in described annular groove, the compact siro spinning technology realized between drag hook and screw mechanism that can be more convenient.
When the top of the canal pin of having tooth pulled out for Wicresoft is not provided with aperture, described canal pin bindiny mechanism can be set to clamping device, and clamping device is by clamping the top of canal pin and the connection realized between itself and canal pin; In the present invention, described clamping device can for realizing arbitrarily the mechanism clamping canal pin, such as, can be clamping rifle or clamping limb; Preferably, described clamping device comprises driving lever, and described driving lever is fixed with Holding seat, and described Holding seat is provided with clamping limb, and described clamping limb is made up of the first clamping limb and the second clamping limb; Live canal pin by the first clamping limb that Holding seat is arranged and the second gripping arm, realize compact siro spinning technology.
