Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to medical instruments, and in particular to a root canal filling device. Background Art
[0002] At present, root canal filling is a key step in root canal treatment. The filling effect directly affects the efficacy of root canal treatment. The success or failure of root canal treatment depends largely on whether the root canal filling is tight or not. At present, most medical staff use handheld instruments to perform manual compaction and filling, which may lead to inadequate and loose filling. The treatment instruments used in these operations are all handheld, and the fingers occupy the patient's mouth, forcing the patient to open his mouth for a long time, which not only causes fatigue, but also often causes joint dislocation and pain. Moreover, when the tooth to be treated is located at the innermost part of the mouth, the fingers are not firmly clamped, and it is easy to control the clamping device poorly. The excessive vertical pressure during the filling process causes the gutta-percha tip to be damaged during the clamping process. Utility Model Content
[0003] The utility model aims to provide a root canal filling device to solve the above problems.
[0004] The above technical objectives of the utility model are achieved through the following technical solutions:
[0005] A root canal filling device comprises a chuck, a handle is connected to the side wall of the chuck, a receiving groove is provided in the chuck which passes through the chuck from top to bottom, a transmission groove is connected to the side wall of the receiving groove, a transmission wheel is rotatably mounted on the inner wall of the transmission groove, a through hole is provided at the center of the transmission wheel, a clamp is threadedly connected to the through hole of the transmission wheel, the clamp is made of rubber, a clamp groove which passes through the chuck from top to bottom is provided in the middle of the clamp, the side wall of the clamp groove is an inclined surface, two symmetrical deformation grooves are provided on the side wall of the clamp groove, and the deformation groove passes through the clamp.
[0006] Beneficial effects: The gutta-percha tip is clamped by the clamp, which makes it convenient for the chuck to control the movement of the root canal in the oral cavity, reducing the contact between the gutta-percha tip and the oral cavity wall. The movement of the clamp is controlled by the thread. The inclined surface inside the clamp can ensure the clamping of the gutta-percha tip during the filling process during the movement. At the same time, the clamping work of the gutta-percha tip is adjusted, and the clamping force of the side of the gutta-percha tip is gradually relaxed to reduce root canal damage.
[0007] Furthermore, a driving groove connected to the transmission groove is provided in the handle, a motor is provided in the driving groove, a driving shaft is connected to the motor, the driving shaft extends into the transmission groove and is connected to a transmission gear, and the transmission gear and the transmission wheel are meshed and connected via a bevel gear set.
[0008] Furthermore, a top ring is detachably connected to the upper side of the clamp, and the top ring extends upward out of the accommodating groove.
[0009] Furthermore, a certain gap is left between the top ring and the side wall of the accommodating groove.
[0010] Furthermore, the lower end of the clamp is connected to a guide head, and a slide groove penetrating from top to bottom is provided in the guide head.
[0011] Furthermore, the lower end of the clamp is slidably connected to the slide slot, and the clamp extends out of the slide slot. BRIEF DESCRIPTION OF THE DRAWINGS
