Abstract

A kind of minimally invasive turnkey, belongs to medical instruments field.Conventional instruments for tooth extraction can produce the strength of harmful extruding or impact to tooth socket in extraction and it is caused to damage, and dental implant be repaired extremely disadvantageous.Therefore, the utility model, which provides, mainly includes a draw bar, it is connected by spiro rod section with screwing in tapping screw；Also include packing ring, the hex nut that L-shaped key is housed thereon, and the support of the installation draw bar, the both sides bottom surface of the support is curved, corresponds to intend extraction tooth both sides each adjacent two adjacent teeths respectively.The top that a paragraph key groove and the L-shaped key in the packing ring are formed with the spiro rod section is mutually matched with system turn；The screw thread Xiang Hu Nogami of hex nut and the spiro rod section closes.The utility model will not produce the strength of harmful extruding or impact in extraction to tooth socket, thus tooth socket is intact, reaches minimally invasive purpose, ensure that the quality of dental implant reparation.

Description

Minimally invasive turnkey

Technical field

It the utility model is related to a kind of medicine equipment, the particularly minimally invasive turnkey for dentistry extraction

Background technology

Conventional Extraction pattern is the corona that tooth to be pulled out is clamped using dental forceps at present, is caused by shaking corona Root of the tooth is fixed on into periodontal ligament in tooth socket to tear, while root of the tooth extruding tooth socket causes its deformation, increased and root of the tooth Between gap, so as to which most tooth pulls out tooth socket at last.When root of the tooth and tooth socket are completely embedded, can also use Clavis, root of the tooth is produced dislocation power using the wedging forces of clavis, tear periodontal ligament, and expand tooth socket.Above-mentioned routine is pulled out Tooth method will necessarily make tooth socket by different degrees of wound due to can produce to the extruding force of tooth socket even impulsive force, Even tooth socket is caused to be fractured.And the alveolar bone due to immediate implant requirement in extraction in teeth socked can not have wound, otherwise The bone tissue of bone regeneration around implant at a specified future date can absorb and cause to plant repairing failure.

Existing foreign data reports a kind of instruments for tooth extraction, is first to be screwed into plan extraction tooth with a screw mutually to fix therewith, then use One steel wire ties the screw, draws the steel wire by draw-gear afterwards and extracts tooth.Complicated, the processing of its draw-gear It is not easy, thus expensive.

The content of the invention

The purpose of this utility model is to provide for a kind of case for the immediate implant that needs to have tooth pulled out at once and designed micro- Wound extraction utensil, it is ensured that will not produce the strength of the extruding being harmful to tooth socket or impact in extraction, and is only produced simultaneously The strength for the traction that root of the tooth is outwards dislocated is born, so as to reach minimally invasive effect, ensures the quality of dental implant.

What the purpose of this utility model was realized in：A kind of minimally invasive turnkey is provided, there is draw bar and screw in plan and pull out The screw of tooth, the draw bar (2) are formed into integral with the tapping screw (2d) for screwing in plan extraction tooth：Its leading portion is Tapping screw (2d), back segment are spiro rod section (2c)；Also include the handwheel (1) for turning draw bar (2), thereon equipped with flat key (1a)；Also packing ring (6), thereon equipped with a L-shaped key (6a) and hex nut (5), and the support of the above-mentioned draw bar (2) of installation (3), the both sides bottom surface of the support (3) is curved, corresponds to intend extraction tooth both sides each adjacent two adjacent teeths respectively；The screw rod In section (2c) top of a paragraph key groove (2b) and the L-shaped key (6a) in the packing ring (6) is formed with to match, the L-shaped key (6a) compared with System turns in the groove on wide bottom insertion support (3) top；(2c) Xiang Nogami closes the hex nut (5) with the spiro rod section.

The spiro rod section (2c) of above-mentioned draw bar (2) and the thread tooth of hex nut (5) is trapezoidal or rectangle, its screw thread bottom Footpath is not less than 10 millimeters.

The diameter in draw bar (2) the end tapping screw portion can between 1.5 millimeters to 3 millimeters, length at 8 millimeters extremely Between 10 millimeters

, can be in support (3) basis rest one according to intending extraction tooth character through when participating in the cintest according to the character for intending extraction tooth The backing plate (4) of property moulding.

The strength of harmful extruding or impact will not be produced to tooth socket in extraction using the utility model, only produced simultaneously The strength of traction outwards dislocated is born, thus tooth socket is intact, is protected well, reaches minimally invasive effect, protects The quality that plantation is repaired, the case especially suitable for the immediate implant that needs to have tooth pulled out at once are demonstrate,proved.If the utility model is used for normal Rule extraction, also all it is favourable to reducing wound, mitigating patient's pain and shorten healing time.The utility model also has knot The advantages of structure is simple, easy to process, manufacturing cost is cheap and easily operated, has a extensive future.

Brief description of the drawings：

Fig. 1 is structural representation of the present utility model.

In figure：1- handwheels, 1a- flat keys, 2- draw bars, 2a- draw bar side keyways, 2b- drawbar length keyways, 2c- are led Draw bar spiro rod section, 2d- draw bar tapping screws, 3- supports, 4- backing plates, 5- hex nuts, 6- packing rings, 6a-L shape keys, 6c- packing rings Bottom.

Embodiment

Illustrate embodiment of the present utility model below in conjunction with accompanying drawing and extraction job step：

Being drilled in ready passage in tooth root pipe first by fiber posts preparation, (channel diameter is preferably slightly less than tapping screw The bottom footpath of screw thread), then with the utility model handwheel 1 flat key 1a key in draw bar 2 side keyway 2a in, turn handwheel 1 drive draw bar 2, which rotates, can be such that the tapping screw section 2b of its leading portion enters in the preparation passage of tooth, and continues screw-in and be intended to extract Root of the tooth, until screw；Complete to remove handwheel 1 after connection, by the long keyway 2b on the flat key 6a alignment draw bars 2 of packing ring 6 Insertion, packing ring 6 is moved down until its base plane 6c and support 3 plane contact, screw in draw bar by hex nut 5 afterwards In 2 epimere screw rod 2c, with hexagon wrench's turn hex nut 5, Tong crosses Luo Wen Nogami and closes transmission, and draw bar 2 is embedded at it The system of L-shaped key 6a in packing ring 6 turns under being oriented to the long keyway of draw bar 2, and draw bar 2 can be removed steadily vertically, until leading Draw root of the tooth outwards dislocate extract tooth.The utility model, can be in 3 basis rest of support, one warp according to the character for intending extraction tooth The backing plate 4 of personalized moulding when participating in the cintest, in order to operate and doctor patient communication.
