Abstract
The utility model provides a conical drill special for a hand machine, and the blade part of the conical drill adopts the three blade conical structure. A conical part adopts the double conical degree transition engagement, and the conical degree of a blade cusp part is greater than the conical degree of the body part of the blade part. A longitudinal U-shaped groove is arranged among blades, and the blade part is provided with a scale groove for displaying the depth. The conical drill uses an international general purpose hand machine standard connecting port and is provided with a middle watering pipe line. A user has convenient operation, and the cooling effect is good. A bone wall in a planting receiving hole can contact a planting body in the largest area, and the planting receiving hole is suitable for various appearances of planting bodies as much as possible. The structure of the U-shaped groove can hold enough cooling liquid and cutting organization chips. The bone hole drilled by the conical drill has easy organization growing and healing process, and the operation effect is good.
Description
This utility model belongs to the medical equipment class, is for tooth-planting tooth usefulness, and preparation coniform spiral implantation body is subjected to one of the instrument in bone grafting hole.
When implanting implantation body during the oral cavity anodontia is repaired, the bone hole need be prepared into the cone that adapts with implantation body in advance, so need the conic drill of special-shaped.There are some shortcomings in the existing brill that generally uses, and shorter as drilling rod, conical section is single tapering, three tough nothings " U " the shape groove, there is not deep calibration sign etc., user operation inconvenience, result of use is not good enough.
Factors such as the design's purpose is to consider the length of implantation body, diameter, tapering, is planted hole internal skeleton wall energy and contacts with the implantation body maximum area, and the operator grasps easily, and is easy to operate design the special-purpose taper of a kind of novel mobile phone and bore.
Major technique content of the present utility model is: the special-purpose taper of mobile phone bores mainly and is made of interface portion (2), bar portion (3) and blade (5) three parts.Blade (5) divides blade tip portion (8) and body again, blade (5) is three tough pyramidal structures, tapering part adopts the double tapered transition and linkage, the tapering of blade tip portion (8) is greater than blade body tapering, three tough have longitudinally " U " shape groove (9) respectively, the blade body has the scale groove (6) of the expression degree of depth, and the tapering of blade tip portion (8) is the 10.0-15.0 degree, and blade body tapering is the 7.0-12.0 degree.There is interface portion (2) upper end of bar portion (3), is international mobile phone standard interface.This taper bores central authorities can filling pipe (4), and water inlet (1) is located at interface portion (2) top, and outlet (7) is located at blade or blade tip portion.Outlet can be single hole, diplopore or trifora, according to the tough number of blade and different.
Major advantage and good effect that taper bores: 1. three of blade tough pyramidal structures are the angles and the boring requirement specialized designs of being planted the hole according to the taper body of implantation body.The tapering of blade is identical with the tapering that the implantation body body does not have the screw thread cone nuclei, and its blade maximum diameter is no more than the maximum diameter after implantation body removes screw thread.This design is for tapping on the basis of this boring, make to be planted pore morphology and approach implantation body's profile most, and make drilling process standardization, stylize.2. three of blade tough structures are for making drill bit stressed when rotated evenly, spin stabilization, the stock-removing efficiency that performance is maximum.3. the longitudinal U-shaped groove on each tough plane of blade is for increasing the space between this plane and bone hole wall, with the liquid coolant of holding capacity and the tissue debris under the cutting, makes the cutting face can not produce too high temperature and causes bone to be burnt.4. water filling type of cooling good cooling results in adopting.5. with the bone hole of this brill preparation, implant implantation body after, planted hole internal skeleton wall energy and contacted with the implantation body maximum area, tissue growth is healed, good operation effect.6. user is easy to operate.
Accompanying drawing and drawing explanation:
Fig. 1. the special-purpose taper of mobile phone bores cutaway view.
Sequence number among the figure: (1) water inlet, (2) interface, (3) bar portion, (4) filling pipe, (5) blade, (6) scale groove, (7) outlet, (8) blade tip portion, (9) " U " shape groove.
Embodiment: taper bores interface portion and adopts international mobile phone standard interface, bar minister 25mm, the diameter 2.35mm of bar portion, the long 16mm of blade, blade upper end diameter 3.1mm, blade tip portion tapering 11 degree, blade body tapering 8 degree, " U " shape groove width 0.9mm, R0.6mm.Water inlet is located at the interface portion top, and three of outlets are located at following 1/3rd places between blade and blade tip portion, filling pipe diameter 0.08mm.
Claims (4)
1. the special-purpose taper of mobile phone bores and it is characterized in that blade (5) is three tough pyramidal structures, and tapering part adopts the double tapered transition and linkage, and blade tip portion (8) tapering is greater than blade body tapering, and three tough have longitudinally " U " shape groove (9) respectively.
2. it is characterized in that by the said brill of claim 1 the blade body has the scale groove (6) of the expression degree of depth.
3. it is characterized in that by claim 1,2 said brills blade tip portion tapering is the 10.0-15.0 degree, blade body tapering is the 7.0-12.0 degree.
4. it is characterized in that by claim 1,2 said brills there is filling pipe (4) in central authorities, water inlet (1) is located at the interface portion top, and outlet (7) is located at blade or blade tip portion, and the number of outlet can be single hole, diplopore or trifora according to the tough number of blade.
