Description

Alveolar bone reduction forceps

Technical Field

The utility model relates to the technical field of dental medical equipment, in particular to alveolar bone reduction forceps.

Background

Alveolar bone refers to the lower edge of the maxilla and the upper edge of the mandible where the root is embedded. Tooth extraction is one of the most common treatment projects in oral clinical practice, and after the tooth is pressed out, in addition to the repair of soft tissues, alveolar bones are also continuously absorbed and reconstructed to finally form tissue repair. If the alveolar bone is damaged or not restored during tooth extraction, imbalance in the absorption and generation of the alveolar bone may be caused, and bone reconstruction may be faster in some places and slower in some places, so that a bone tip or a bony prominence may be formed. In addition to discomfort to the patient, late repair may also be affected. Therefore, the current oral cavity is usually used tooth forceps to reset the alveolar bone after the tooth is pulled out in clinic, however, because tooth forceps both ends are tiny and sharp, the operation degree of difficulty is big, is difficult for the atress when carrying out the reset of alveolar bone, easily takes off and leads to resetting not in place, damages the alveolar bone even once more.

Detailed Description

To facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to specific embodiments and drawings.

Referring to fig. 1-3, a preferred embodiment of the present invention is as follows.

An alveolar bone reduction forceps comprises two handles 1, wherein the two handles 1 are mutually crossed and hinged, a forceps mouth 2 is arranged at the hinged part of the two handles 1 along the length direction of the handles 1, a flat clamping block 21 is arranged at the end part of the forceps mouth 2, and two opposite surfaces of the two flat clamping blocks 21 are arc surfaces; one of the two handles 1 is provided with an adjustable buffer device 3, the other handle is provided with a positioning block 4 matched with the buffer device 3, and the buffer device 3 is used for buffering the force of the reset pliers during clamping. The alveolar bone pincers that reset of this embodiment, tip at pincers mouth 2 is equipped with has the flat clamp splice 21 of arcwall face, through increasing the area of contact of pincers that reset when using as far as possible with the alveolar bone for when resetting the alveolar bone, because 2 tip of pincers mouth wider more, the stress point of pincers on the alveolar bone that reset is more, area of contact is bigger, pressure is littleer, consequently can effectively avoid the pincers that reset to break away from the alveolar bone, also can avoid the further damage to the alveolar bone.

In addition, still be equipped with buffer 3 on handle 1, buffer 3 in this embodiment has the function that resets and cushion simultaneously, and through buffer 3's buffer function, the doctor is getting alveolar bone when restoreing, and buffer 3's feedback can more clearly sense the dynamics of getting, avoids because of the skew or the damage of exerting oneself excessively to lead to alveolar bone. Because the doctor needs to loosen and clamp the reduction forceps repeatedly, the reduction forceps can be automatically opened through the reduction function of the buffer device 3 after the doctor loosens the reduction forceps, the reduction forceps can be conveniently pulled out of the alveolar bone, the doctor does not need to open the reduction forceps by himself, and therefore the operation intensity of the doctor is relieved.

In this embodiment, the arc-shaped surface of one of the flat clamping blocks 21 is provided with a buffer layer 212, and the arc-shaped surface of the other flat clamping block 21 opposite to the buffer layer is provided with anti-slip teeth 211. The buffer layer 212 is any one of a rubber layer, a soft plastic layer, and a sponge layer. Because alveolar bone is the not hard up fragile one end that resets usually when resetting, consequently when using the pincers that reset of this embodiment, the pincers mouth 2 that has buffer layer 212 contacts with not hard up alveolar bone, and the one end that has anti-skidding tooth 211 contacts with fixed alveolar bone to avoid haring the alveolar bone, thereby guarantee the integrality of alveolar bone, be convenient for subsequent self-repair.

In this embodiment, the buffering device 3 includes a limiting block 31, an adjusting screw 32 and a limiting rod 33, the limiting block 31 is fixedly connected with the handle 1, a limiting cavity 311 is arranged inside the limiting block 31, the adjusting screw 32 and the limiting rod 33 are both movably connected with the limiting cavity 311, and an elastic member 34 is arranged in the limiting cavity 311. The adjusting screw rod 32 is in threaded connection with the limiting block 31, one end of the adjusting screw rod 32 is located in the limiting cavity 311, and the other end of the adjusting screw rod 32 is located outside the limiting cavity 311; one end of the limiting rod 33 is clamped in the limiting cavity 311, the other end of the limiting rod is abutted against the positioning block 4, and the elastic piece 34 is clamped between the adjusting screw rod 32 and the limiting rod 33.

Adjusting screw 32 and gag lever post 33 of this embodiment are located relative position, and when using, its initial condition does, gag lever post 33 butt struts the pincers that reset on locating piece 4, when extrudeing two handles 1, elastic component 34 compression produces elasticity to play the cushioning effect of certain degree, and gag lever post 33 butt all the time on locating piece 4, when loosening two handles 1, because the elasticity that elastic component 34 compression produced can make two handles 1 automatic re-setting. It should be noted that, because the two handles 1 are hinged, the track of the rotation is arc-shaped, and in order to make the buffer device 3 work smoothly, the inner diameter of the limiting cavity 311 should be slightly larger than the inner diameter of the spring, and the sliding gap between the limiting block 31 and the limiting rod 33 should also be larger.

In this embodiment, an adjusting knob 321 is fixedly disposed at one end of the adjusting screw 32 outside the limiting cavity 311. Because the adjusting screw 32 is in threaded connection with the limiting block 31, the initial compression degree of the elastic member 34 is controlled by controlling the position of the adjusting screw 32, so that the buffering elastic force of the elastic member 34 is controlled to adapt to various different use conditions.

In the present embodiment, the elastic member 34 is a metal spring or an elastic rubber, and preferably a metal spring.

In this embodiment, the end portions of the two handles 1 are both provided with the grips 5, and the grips 5 are in a circular ring structure. The circular structure can be used for inserting fingers, on one hand, the extrusion of the reduction forceps is convenient to apply force, and on the other hand, the stability of holding the reduction forceps can be effectively improved.

While the invention has been described in conjunction with the specific embodiments set forth above, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations that fall within the spirit and scope of the appended claims.
