Description
Technical Field
The utility model relates to an appliance in dentistry; in particular to a ring drill for taking broken roots.
Background
The dead pulp teeth treated by the root canal are brittle and are easy to break when being extracted, if the broken root is longer, the dead pulp teeth can be extracted again, and if the broken root is deeper, the dead pulp teeth are not easy to clamp; as shown in fig. 1, the method for taking the broken tooth root is that a round drill bit is used for grinding the broken tooth root, all the broken tooth root is ground into powder, and then the powder is washed by water to complete the grinding and cutting process; the grinding time is long, and the finished cavity is irregular.
Dead pulp teeth are usually accompanied by other symptoms, such as periapical periodontitis, granulation tissue and abscess around the root tip, and are not easy to grind; still other dead teeth may be prematurely filled and may require a canal treatment to remove infected cementum by cutting away around the root tip.
Disclosure of Invention
The utility model discloses it is not enough to prior art, provide one kind be suitable for the root surface level, not leave the piece get disconnected root trephine.
In order to solve the technical problem, the utility model discloses a following technical scheme can solve:
a ring drill for cutting off the root of a tree is composed of a drill rod with a central hollow drill sleeve, several grinding racks and a spiral chip-removing slot.
The water injection hole is arranged on the peripheral wall or the tail end of the hollow drill bit.
The drill rod is gradually tapered, and a spherical grinding head is arranged at the end head.
The middle end of the drill rod is provided with a step in a threaded mode, and a silica gel pad is arranged between the step and the hollow drill bushing.
Compared with the prior art, the utility model, following beneficial effect has: along the growth direction of the broken root, the broken root and the infected alveolar bone around the broken root are completely removed at one time by using the hollow drill bushing, the operation is simple, and the subsequent filling is also convenient; exploring the growth direction of the tooth through a spherical grinding head so as to facilitate the drilling orientation and positioning of the hollow drill bushing; in addition, the spherical grinding head also has a central stabilizing function, so that the drill bushing is prevented from slipping.

Fig. 3 is a schematic structural diagram of two short rod embodiments of the present invention.
Fig. 4 is a schematic structural diagram of two kinds of embodiments of the long rod of the present invention.
Fig. 5 is a schematic diagram of the external structure of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: as shown in fig. 1-5, the labels are as follows: the hollow drill bushing 01, a drill rod 02, a silica gel pad 03, a cavity 11, sawteeth 12, a water injection hole 13, a grinding rack 14, a chip removal groove 15, a spherical grinding head 21, a step 22, an alveolar bone 04, a broken root 05 and periapical sclerotin 06.
A ring drill for taking broken roots comprises a drill rod 02 and a hollow drill sleeve 01 which are matched by screw threads and can also adopt a plug-in buckle type with a square end, wherein the center is a cavity 11, the front end is opened, and sawteeth 12 are uniformly distributed on the edge of the opening; the working principle is as shown in figure 2, the broken root is aimed at and drilled downwards, the broken root 05 and the periapical sclerotin 06 around the broken root are cut into a whole and separated from the alveolar bone 04, then the broken root is slightly pried by a dental collar, and the broken root is clamped out by a pair of tweezers after the bottom is broken.
As shown in fig. 3: the hollow drill sleeve can be in a circular sleeve shape, preferably a wieldy head, the wall of the hollow drill sleeve is provided with a plurality of water injection holes 13, a plurality of grinding racks 14 are uniformly distributed outside the wall, or the periphery of the hollow drill sleeve is coated with grinding materials and is provided with a chip removal groove 15 which is spiral, so that broken bone chips can overflow.
The water injection hole sets up at the perisporium or the tail end of hollow drill, and during the operation, the delivery port of the handheld aircraft nose of dentistry can spray cooling water, and water pours into from the water injection hole that is located the afterbody, flows out in water injection hole or other gaps on the perisporium, and the water injection hole on the perisporium can play the effect of cooling down and reduction bone meal when the grinding.
As shown in fig. 4, the drill rod is gradually tapered, and a spherical grinding head 21 is arranged at the end head, can be clamped in a central hole of a broken root, and can adjust the drilling direction along the direction of the root of the tooth from the top to the bottom during operation so as to play a guiding role; the middle end of the drill rod is provided with a step 22, and a silica gel pad 03 is arranged between the step and the hollow drill bushing to prevent looseness.
Equivalent designs similar to those described herein are also within the scope of the present application.
