The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
As shown in fig. 2 to 7, the present utility model provides an endodontic file device which is convenient to replace, comprising: a connecting sleeve 1, a root canal file body 2, a locking mechanism 3 and a linkage mechanism 4. The connecting sleeve 1 is adapted to mount a locking mechanism 3 and a linkage mechanism 4. The file body 2 is adapted to be mounted to a locking mechanism 3. The locking mechanism 3 is adapted to clamp the file body 2 to the linkage mechanism 4. The linkage 4 is adapted to drive the locking mechanism 3 to open or close. The above components are described in detail below.
The connecting sleeve 1, the connecting sleeve 1 is cylindrical as a whole, and the axis of the connecting sleeve 1 is provided with a through hole along the length direction. Be suitable for installation locking mechanical system 3 and link gear 4 on the connecting sleeve 1, root canal file body 2 can be installed in connecting sleeve 1 one side through link gear 4, and a handle can be connected to connecting sleeve 1 opposite side to make things convenient for the operator to control root canal file device.
The root canal file body 2, root canal file body 2 detachable sets up in connecting sleeve 1 one side, and the root canal file is suitable for pegging graft with link gear 4.
And the locking mechanism 3 is arranged on one side of the connecting sleeve 1 away from the handle, the locking mechanism 3 is suitable for being opened or closed along the radial direction of the connecting sleeve 1, when the locking mechanism 3 is opened, the connecting sleeve 1 is in an open state, and when the locking mechanism 3 is closed, the connecting sleeve 1 is in a closed state.
The structure of the locking mechanism 3 will be specifically described, and the locking mechanism 3 includes two locking blocks 31 disposed in mirror image, and the locking blocks 31 are hinged to one end of the connection sleeve 1. The locking blocks 31 can be rotated along the coupling sleeve 1 to open or close the coupling sleeve 1, respectively. The outer wall of the locking block 31 is matched with the outer wall of the connecting sleeve 1, so that the locking block 31 can form a complete column with the connecting sleeve 1. Through the above-mentioned setting for during the installation, two locking pieces 31 can rotate around the articulated department with connecting sleeve 1 separately to take on the open condition, the root canal file body 2 can insert in the link gear 4 along the axial of connecting sleeve 1 this moment. After the root canal file body 2 is inserted into the linkage mechanism 4, the two locking blocks 31 can rotate around the hinge part of the connecting sleeve 1 in opposite directions to present a closed state, and at the moment, the two locking blocks 31 can clamp and limit the root canal file body 2 from two sides so as to prevent the root canal file body 2 from being separated from the linkage mechanism 4.
In order to achieve the above effect, one end of the root canal file body 2 is provided with a limiting ring 21, and the inner wall of the locking block 31 is provided with a limiting groove 32. The limiting ring 21 corresponds to the limiting groove 32. Specifically, after the root canal file body 2 is inserted into the linkage mechanism 4, the limiting ring 21 can be abutted with the limiting groove 32, and when the two locking blocks 31 rotate in opposite directions, the limiting groove 32 can be clamped with the limiting ring 21 from two sides, so that the root canal file body 2 is positioned between the two locking blocks 31.
The link mechanism 4, link mechanism 4 sets up in connecting sleeve 1 inboard, and link mechanism 4 is suitable for and connecting sleeve 1 length direction is flexible, and root canal file body 2 is suitable for inserting into link mechanism 4. The link mechanism 4 is linked with the lock mechanism 3, specifically, when the link mechanism 4 extends in the longitudinal direction, the link mechanism 4 can push the two lock blocks 31 to rotate away from each other. When the link mechanism 4 is contracted in the longitudinal direction, the link mechanism 4 can pull the two locking blocks 31 to rotate in opposite directions. By the above arrangement, when the operator controls the link mechanism 4 to extend and retract, the two lock blocks 31 can be driven to open or close. Specifically, during installation, the linkage mechanism 4 pushes the locking block 31 to open along the radial direction of the connecting sleeve 1. After the root canal file body 2 is inserted into the linkage mechanism 4, the linkage mechanism 4 pulls the locking block 31 to be radially closed.

Through the above arrangement, when the positioning column 41 slides along the axial direction of the connecting sleeve 1 towards the locking blocks 31, the positioning column 41 can push the two locking blocks 31 so as to open the two locking blocks 31. After the root canal file body 2 is inserted into the positioning column 41, the positioning column 41 slides reversely, and the positioning column 41 pulls the root canal file body 2 so that the limiting ring 21 pushes the two locking blocks 31 to slide oppositely.
In order to facilitate the operator to operate the positioning column 41, the positioning column 41 is provided with a driving slot 411 along the radial direction, and an arc-shaped block 412 is arranged in the driving slot 411. The connecting sleeve 1 is provided with a linkage hole 11 along the radial direction, a floating block 12 is arranged in the linkage hole 11, and the floating block 12 is abutted with the arc-shaped block 412. The slider 12 is limited in the linkage hole 11, and when an operator presses the slider 12 inwards, the slider 12 can push the arc-shaped block 412, so that the arc-shaped block 412 drives the positioning column 41 to slide towards the locking block 31, and the positioning column 41 pushes the two positioning blocks to open.
For convenient insertion of the file body 2 into the positioning column 41, the file body 2 is also circumferentially limited, and the positioning column 41 faces one end of the file body 2 to form a hexagonal groove 413. The end of the file body 2 facing the positioning column 41 is provided with a hexagonal positioning block 22, and the hexagonal positioning block 22 corresponds to the hexagonal groove 413. Through the above arrangement, the root canal file body 2 is inserted into the positioning column 41.
In order to avoid that the operator touches the slider 12 by mistake when using the file device, said slider 12 is recessed in the outer wall of said coupling sleeve 1.
