Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and particularly relates to a handle for a root canal file. Background Art

[0002] In dental treatment, root canal files are sometimes needed. Root canal files are very small and need to be connected to a handle for easy operation.

[0003] The current handle, such as that disclosed in patent application publication number CN110638536A, does not allow the root canal file to rotate during dental treatment. During use, tooth debris accumulates in the file gap, affecting the filing effect. In this case, the root canal file needs to be rotated at an angle so that the side with less tooth debris in the file gap faces the treatment area. Currently, the root canal file tube cannot be rotated in the oral cavity, and sometimes the dentist can only rub the root canal file back and forth with the thumb and index finger, which is extremely inconvenient. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to design a handle for a root canal file so that the root canal file tube can be rotated in the oral cavity to facilitate the operation of the dentist.

[0007] The pin shaft is a screw, the clamping piece has a clamping cavity, the tip of the screw passes through the clamping piece from the clamping cavity to reach the screw hole of the support piece, and the screw is threadedly connected to the support piece.

[0008] An elbow shell is provided outside the support member, and the elbow shell wraps the bevel gear and the support member.

[0009] The bevel gear includes a bevel gear A and a bevel gear B. The bevel gear A is integrally formed with the handle rotating part, and the bevel gear B is integrally formed with the clamping part.

[0010] The clamping piece includes a locking nut for fixing the root canal file placed in the clamping cavity of the clamping piece.

[0011] The support rod is fixed to the support member by threads.

[0012] The included angle between the axis of the pin and the axis of the support rod is 60-140°; the clamping member is used to clamp the root canal file;

[0013] The support rod and the support member are both metal parts; the handle fixing part is provided with a hollow part assembled with the support rod, the hollow part is connected to the outside world at the tail end of the handle fixing part, and the tail end of the handle fixing part is fixed with a plug.

[0014] The handle fixing portion fixes the palm grip, and an angle is formed between the handle fixing portion and the palm grip.

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 This is a schematic diagram of the utility model Figure 1 .

[0018] Figure 2 yes Figure 1 Enlarged diagram of the left end.

[0019] Figure 3 This is a schematic diagram of the utility model Figure 2 . DETAILED DESCRIPTION

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.

[0021] like Figure 1-2 A handle for a root canal file includes a handle fixing portion 6 and a handle rotating portion 7. The handle fixing portion 6 fixes a support rod 9. The handle rotating portion 7 is sleeved outside the support rod 9 and can rotate along the support rod 9. The support rod 9 fixes a support member 10. The support member 10 fixes a pin shaft 3. The axis of the pin shaft 3 and the axis of the support rod 9 have an included angle. A clamping member 4 is sleeved on the outside of the pin shaft 3, and the clamping member 4 can rotate around the pin shaft 3. The clamping member 4 is connected to the handle rotating portion 7 through a bevel gear. The clamping member 4 is used to clamp the root canal file 1.

[0022] like Figure 1-2 The support rod 9 and the support member 10 are both metal parts, and the support is relatively stable and firm.

[0023] like Figure 1-2 The pin 3 is a screw, and the clamping member 4 has a clamping cavity 23. The tip of the screw passes through the clamping member 4 from the clamping cavity 23 and reaches the screw hole of the support member 10, and the screw is threadedly connected to the support member 10. In this way, the clamping member 4 is stuck between the support member 10 and the nut of the screw and can rotate stably.

[0024] like Figure 1-2 In order to prevent the bevel gear from damaging the oral cavity, an elbow shell 5 is provided outside the support member 10, and the elbow shell 5 wraps the bevel gear and the support member 10.

[0025] like Figure 2 The bevel gears include a bevel gear A21 and a bevel gear B22. The bevel gear A21 is integrally formed with the handle rotating portion 7, and the bevel gear B22 is integrally formed with the clamping member 4. For example, the clamping member 4 and the handle rotating portion 7 can be made of plastic parts and can be integrally formed by injection molding. This makes it easier to fix relatively small parts together and ensures accuracy.

[0026] like Figure 1-2 The clamping member 4 includes a locking nut 2 for fixing the root canal file 1 placed in the clamping cavity 23 of the clamping member 4.

[0027] The support rod 9 is fixed to the support member 10 by threads.

[0028] The included angle between the axis of the pin 3 and the axis of the support rod 9 is 60-140°.

[0029] like Figure 1 The handle fixing portion 6 is provided with a hollow portion for assembling with the support rod 9 , the hollow portion is connected to the outside world at the tail end of the handle fixing portion 6 , and the plug 8 is fixed at the tail end of the handle fixing portion 6 .

[0030] like Figure 3 , the handle fixing portion 6 fixes the palm grip 12. There is an angle between the handle fixing portion 6 and the palm grip 12.

[0031] like Figure 3 The palm holding piece 12 is sleeved on the outside of the handle fixing portion 6 for easy processing.

[0032] Its working principle is:

[0033] When using,

[0034] S1. Installing the root canal file: Loosen the locking nut 2, place the root canal file 1 into the clamping cavity 23, and then tighten the locking nut 2.

[0035] S2. When using: place the handle fixing part 6 on the base of the thumb, hold the palm grip 12 with the little finger and ring finger, and use the thumb, index finger and middle finger to clamp and rotate the handle rotating part 7 to complete the treatment.

[0036] It can also be Figure 1 As shown, the handle for the root canal file is not equipped with a palm grip 12 .

[0037] Features of this application:

[0038] During treatment, the up-and-down movement of the wrist allows the file 1 to move up and down, a fundamental task. However, because the thumb, index finger, and middle finger can rotate the handle rotating portion 7, the handle rotating portion 7 drives the gripper 4 and the file 1 to rotate synchronously. This combines the up-and-down movement of the file 1 with the rotational motion, causing the file 1 to perform a spiral motion within the oral cavity, facilitating tooth filing and treatment.

[0039] S2. The hammer handle plate 41 cooperates with the opening of the slider 2 to constrain the sliding posture of the slider 2, thereby improving the stability of the slider 2 sliding along the hammer rod 5.

[0040] S3. The support rod 9 and the support member 10 are designed separately to facilitate processing.

[0041] For other contents, please refer to the prior art.

[0042] The above description is only the preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
