Technical Field

[0001] The utility model relates to the technical field of root chargers, in particular to a protective device for a thermal head of a root charger. Background Art

[0002] Root canal therapy is a dental procedure used to treat tooth infection and pulpitis. During root canal therapy, the doctor will use a root canal filler to fill the root canal to prevent bacteria from entering again.

[0003] At present, the root filling stage of root canal treatment mainly uses the hot melt gutta-percha tip of the root filling machine to vertically pressurize and fill. The temperature of the root filling machine with a hot head is as high as 200°C or above. Sometimes the lip and cheek mucosa are not pulled sufficiently or cannot be pulled, which can easily burn the patient's lips and mucosa. At the same time, when the teeth are positioned backward or the teeth are tilted toward the cheek and tongue, part of the oral mucosa, lips, and tongue will block the filling field of view, making it inconvenient to operate. Therefore, we propose a protective device for the hot head of the root filling machine. Utility Model Content

[0009] Furthermore, one side of the moving block is fixedly connected to a connecting column, and the other end of the connecting column is fixedly connected to a rubber arc plate.

[0010] Furthermore, an eccentric cam is movably connected to the inner side of the through hole, a handle is fixedly connected to the outer side of the eccentric cam, and the eccentric cam is located on the inner side of the through hole.

[0011] Furthermore, the shaft portion of the eccentric cam is slidably connected to the inner side of the runway groove, and the shaft portion of the eccentric cam is rotationally connected to the inside of the connecting rail.

[0023] The effect achieved by the entire embodiment 1 is that the cam handle 31 is pried open by tweezers, and the column rod 32 is connected to the cam handle 31 in an eccentric state, so the cam handle 31 in the initial horizontal state is flipped around the column rod 32 to a vertical state, and the cam part of the cam handle 31 squeezes the sleeve 33, and the sleeve 33 slides on the connecting shaft 34 and squeezes the two ends of the outer hoop 35, thereby the outer hoop 35 clamps and limits the heat insulation hose 4 to prevent scalding the patient's lips or oral mucosa.

[0024] Embodiment 2, as Figure 1 - Figure 4As shown, the difference between this embodiment and embodiment 1 is that both sides of the outer hoop 35 are fixedly connected with connecting rails 28, the inner side of each group of connecting rails 28 is slidably connected with a moving block 23, the middle part of the moving block 23 is provided with a through hole 26 and a runway groove 27, the through hole 26 and the runway groove 27 penetrate, one side of the moving block 23 is fixedly connected with a connecting column 22, the other end of the connecting column 22 is fixedly connected with a rubber arc plate 21, the inner side of the through hole 26 is movably connected with an eccentric cam 24, the outer side of the eccentric cam 24 is fixedly connected with a handle 25, the eccentric cam 24 is located on the inner side of the through hole 26, the shaft of the eccentric cam 24 is slidably connected to the inner side of the runway groove 27, and the shaft of the eccentric cam 24 is rotatably connected to the inside of the connecting rail 28.

[0025] The effect achieved by the entire embodiment 2 is that by using tweezers to pry the handle 25, the handle 25 drives the eccentric cam 24 to rotate a certain angle in the through hole 26, the axis of the eccentric cam 24 is in an eccentric state, and the protrusion of the eccentric cam 24 pushes the moving block 23 outward, and the moving block 23 slides on the inner side of the connecting rail 28, and under the connection of the connecting column 22, pushes the rubber arc plate 21 to move outward, and the other external support mechanism 2 is operated in the same way, thereby the two rubber arc plates 21 expand outward, open the lips or oral mucosa that blocks the filling field of view, and help expose the field of view of the root canal filling operation, thereby making it more convenient for the operator to actually operate and improving work efficiency.

[0026] Working principle: When using the heat-carrying head protection device for the root charger, the heat-insulating hose 4 and the limiting mechanism 3 are placed on the middle part between the turning point of the heat-carrying head of the root charger body 1 and the handle. After adjusting the direction of the external support mechanism 2, the cam handle 31 is moved with the help of tweezers. The column 32 is connected to the cam handle 31 in an eccentric state, so the cam handle 31 in the initial horizontal state is turned around the column 32 to a vertical state. The cam of the cam handle 31 squeezes the clamping sleeve 33, and the clamping sleeve 33 slides on the connecting shaft 34 and squeezes the two ends of the outer hoop 35, so that the outer hoop 35 clamps and limits the heat-insulating hose 4. The handle 25 is also used to pry open the eccentric cam 24, which drives the eccentric cam 24 to rotate a certain angle in the through hole 26. The axis of the eccentric cam 24 is in an eccentric state. The protrusion of the eccentric cam 24 pushes the moving block 23 outward. The moving block 23 slides on the inner side of the connecting rail 28, and is connected with the connecting column 22 to push the rubber arc plate 21 outward. The other external support mechanism 2 is operated in the same way, so that the two rubber arc plates 21 expand outward to open the lips or oral mucosa that block the filling field of view, thereby helping to expose the field of view of the root canal filling operation.
