The utility model provides a dental elevator which is used for tooth root extraction operation.
Description
Technical Field
The utility model relates to the technology of medical instruments, in particular to a technology of a dental elevator for tooth root extraction.
Background
In the oral cavity outpatient service, need the doctor to wedge the tappet beak of elevator into the nearly middle part of suffering from tooth when extracting the root of suffering from tooth, application of force prizes the root of suffering from tooth again, because the tappet of current elevator is all fixed on the tappet, and tappet also all are straight type, doctor's operative hand is located the dead ahead in patient's oral cavity, can influence doctor's operation field of vision, consequently, the doctor needs tractive patient angle of mouth by a relatively large margin in order to obtain good operation field of vision, draw wound patient angle of mouth easily, and whole elevator can all move when oral cavity outside application of force in addition, the easy skew of elevator during application of force, damage to suffering from tooth peripheral tissue is great.
SUMMERY OF THE UTILITY MODEL
To overcome the defects in the prior art, the utility model aims to solve the technical problem of providing a dental elevator for tooth root extraction, which can avoid the mouth and corner strain of a patient when the broken root of an affected tooth is extracted and can also reduce the damage of peripheral tissues of the affected tooth.
In order to solve the technical problem, the utility model provides a tooth root is pulled out and is used elevator which comprises tappet stem, tappet rod, its characterized in that:
the tappet is an L-shaped pipe fitting, a rotatable vertical rotating rod and a rotatable transverse rotating rod are arranged in a pipe cavity of the tappet and are perpendicular to the transverse rotating rod, bevel gears are respectively fixed at the lower end of the vertical rotating rod and the right end of the transverse rotating rod, the bevel gears on the vertical rotating rod and the transverse rotating rod are meshed with each other, so that the vertical rotating rod and the transverse rotating rod can synchronously rotate, a grab handle is fixed at the upper end of the tappet, a rotatable operating handle is arranged on the grab handle, and the upper end of the vertical rotating rod is coaxially and fixedly connected with the operating handle;
the movable ring is sleeved on the transverse rotating rod and is in threaded fit with the transverse rotating rod;
the lower end of the tappet is provided with a tappet beak, the upper part of the tappet is pivoted with the left part of the tappet, a connecting rod is arranged on the tappet rod body above the pivot, the left end of the connecting rod is pivoted with the tappet, and the right end of the connecting rod is pivoted with the movable ring.
Furthermore, the tip of the elevator beak faces to the left, and the root part of the right side of the elevator beak is provided with a beak process protruding towards the front side and the rear side.
The utility model provides a root of tooth is pulled out and is used very, the stiff handle adopts L shape structure, doctor's action hand is located the side in patient's oral cavity, can not influence doctor's operation field of vision, consequently, it is less to the tractive range of patient angle of mouth, can avoid patient angle of mouth to pull out when suffering from the broken root of tooth, and very beak wedges after suffering from the nearly well position of tooth, the doctor only need rotate the action handle and just can order about the jib pivot, thereby control very beak point-end and arrive incomplete root section sled smoothly and suffer from the broken root of tooth, other parts except that action handle and tappet all need not move, very beak is difficult to the skew, the beak process that can also utilize very beak root portion is adjacent supports the tooth as the impetus, can reduce the damage to suffering from the peripheral tissue of tooth.
Drawings
Fig. 1 is a partially cut front view of a dental elevator for root extraction according to an embodiment of the present invention.
Detailed Description
The following description will be made in detail with reference to the accompanying drawings, but the present embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention, and the relations between the numbers of the components in the present invention are shown.
As shown in fig. 1, the dental elevator for tooth root extraction provided by the embodiment of the present invention comprises a tappet stem and a tappet rod 5, and is characterized in that:
the vertical rotating rod and the transverse rotating rod can synchronously rotate, a grab handle 2 is fixed at the upper end of the tappet, a rotatable operating handle 1 is arranged on the grab handle, and the upper end of the vertical rotating rod 6 is coaxially and fixedly connected with the operating handle 1;
the transverse rotating rod 7 is sleeved with a movable ring 8, and the movable ring 8 is in threaded fit with the transverse rotating rod 7;
a tappet beak 11 is formed at the lower end of the tappet 5, the upper part of the tappet 5 is pivoted with the left part of the tappet, a connecting rod 9 is arranged on the tappet rod body above the pivot 13, the left end of the connecting rod 9 is pivoted with the tappet 5, and the right end of the connecting rod 9 is pivoted with the movable ring 8;
the tip of the elevator beak 11 faces to the left, and the root part of the right side of the elevator beak is provided with a beak process 12 protruding towards the front side and the rear side.
The embodiment of the utility model provides a tooth root removing operation for oral cavity outpatient service, its using-way is as follows:
a doctor holds the grab handle 2 by hand, extends the tappet rod 5 into the mouth of a patient, wedges the tip of the tappet 11 into the middle part of the affected tooth, and positions the grab handle 2 at the side of the mouth of the patient;
after the lifting beak 11 reaches the target position, the tooth root extraction operation can be directly carried out, or the coracoid process 12 at the root of the lifting beak can be firstly utilized to prop against the adjacent teeth as an acting point, the force is applied (the grab handle can move at the moment) to lift and loosen the affected tooth, and the tooth root extraction operation is carried out after the affected tooth is loosened to a certain degree;
when the tooth root extraction operation is carried out, the position of the grab handle 2 is kept still, the operation handle 1 is rotated to drive the tappet rod 5 to pivot, so that the tip of the tappet 11 moves towards the affected tooth to reach the broken root section, the broken root of the affected tooth is pried, and the extraction of the broken root of the affected tooth is realized.
