Description

TECHNICAL FIELD

[0001] The utility model relates to oral medical instrument technical field, concretely is a tooth extraction auxiliary tool. BACKGROUND

[0002] In the operation of removing caries and wisdom teeth, for the condition that the tooth crown is damaged but the tooth root is relatively healthy, the connection between the tooth root and the alveolar bone is tight, at this time, the tooth elevator needs to be inserted into the periodontal membrane, and the tooth root is pried out through high-frequency vibration. However, in this process, due to the problems of bleeding at the tooth extraction site, patient's saliva, etc., and the fact that the tail part of some tooth roots is in the form of a small hook and is hooked in the alveolar bone (many patients' wisdom teeth often have this form, or the teeth with developmental abnormalities also have hooks), the tooth elevator often cannot be completely inserted into the tail part of the tooth root to make it completely separate from the alveolar bone, at this time, although the tooth seems to have loosened, the tail part of the tooth root is still connected relatively tightly to the alveolar bone, and the patient cannot accurately feedback to the medical staff due to the effect of anesthetic, if the tooth elevator is directly hit or the tooth forceps are used, the tail part of the tooth root is small, which often leads to the breakage of the tail part of the tooth root and the loss of the tail part in the alveolar bone, affecting the closure of the incision of the patient, bringing discomfort to the recovery of the patient, and in some cases, it can also cause the alveolar bone to be pulled and damaged (the alveolar bone is relatively thin), if the tooth needs to be implanted at this place later, it will affect the success rate.

DETAILED DESCRIPTION

[0020] The technical scheme of the utility model will be described in detail below with reference to the drawings.

[0021] The following embodiments are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical terms used have the same meaning as understood by those skilled in the art to which the present application belongs. It should be noted that the terms used are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0022] The embodiment is a tooth extraction auxiliary tool, which comprises a main body 1, a water supply pipeline and a drainage pipeline. The main body 1 comprises a shell 11, an impact head 12, a transmission assembly and a drive assembly arranged in the shell 11. A booster 3 is arranged on the water supply pipeline. The booster 3 can be a Venturi tube. A check valve 4 is arranged on the drainage pipeline to prevent backflow of waste water.

[0023] The drive assembly comprises a drive cover 6, a water inlet 61, a drainage outlet 62 and a water wheel 63. The drive cover 6 is fixed to the shell 11. The water inlet 61 and the drainage outlet 62 are arranged above and below the drive cover 6 respectively. The water wheel 63 is installed in the drive cover 6 and is aligned with the water inlet 61. The water inlet 61 is connected to tap water through the water supply pipeline to serve as the driving force of the water wheel 63. A switch valve is arranged on the water supply pipeline. The switch valve can be a foot switch valve 2, which facilitates control of the water flow rate (pressure). The drainage outlet 62 is connected to the waste water tank 5 through the drainage pipeline.

[0024] The transmission assembly comprises an eccentric wheel 13 and a transmission rod set. The upper end of the transmission rod set contacts the eccentric wheel 13, and the lower end is connected to the impact head 12. A spring 17 for resetting is arranged on the transmission rod set. The water wheel 63 is connected to the eccentric wheel 13 through a rotating shaft to drive the impact head 12 to reciprocate through the transmission rod set. Various conventional sealing structures, such as sealing sleeves and sealing pads, are arranged between the drive assembly and the transmission assembly.

[0025] Specifically, the transmission rod group comprises a top rod 14 and a striking rod 16 in sequence, the upper end of the top rod 14 contacts the eccentric wheel 13, the lower end contacts the upper end of the striking rod 16, and the lower end of the striking rod 16 is screwed with the striking head 12, so that the suitable striking head 12 can be replaced according to different parts and different sizes of teeth. The spring 17 is sleeved on the striking rod 16, and the striking rod 16 is provided with a protruding shoulder 18 to limit the spring 17.

[0026] Further, the housing 11 is further provided with a fixed sleeve 15, the fixed sleeve 15 is provided with a sliding hole, the lower part of the top rod 14 and the upper part of the striking rod 16 are respectively slidingly inserted into the sliding hole of the fixed sleeve 15, which plays a guiding and fixing role and reduces the shaking of the transmission rod group when reciprocating; the inner wall of the sliding hole of the fixed sleeve 15 is provided with a sliding groove, and the upper part of the striking rod 16 is provided with a sliding block 19 matched with the sliding groove.

[0027] When the tool is used, the main body 1 is connected with the water supply pipeline and the drainage pipeline, the medical staff controls the water flow speed by stepping on the foot switch valve 2, uses the pressure of tap water itself and the booster 3 to make the water flow impact the water wheel 63 to rotate and drive the eccentric wheel 13 to rotate, and under the action of the spring 17, the top rod 14 and the striking rod 16 reciprocate and retract, and the striking head 12 reciprocates and strikes the tooth, gradually loosening the root tail from the alveolar bone. If the medical staff exerts greater force, etc. to cause the striking force between the tooth and the striking head 12 to be too large, the top rod 14 will press the eccentric wheel 13 to cause it to be stuck, and the water wheel 63 will stop or slow down. Since it is water-driven, it will not be damaged due to being stuck, and the medical staff can observe that the striking head 12 no longer reciprocates and retracts, and it is known that the force is too large, at which time the striking force can be reduced or the stepping force of the foot switch valve 2 can be adjusted, so as to avoid the root tail from being broken or the alveolar bone from being damaged.

[0028] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some changes or improvements can be made without departing from the principle of the present application, and these changes or improvements should be regarded as the protection scope of the present application.
