Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a dental root canal cleaning file. Background Art

[0002] Root canal therapy, also known as endodontic treatment, is a dental procedure used to treat pulp necrosis and root infection. This procedure preserves the tooth, thus complementing tooth extraction. However, the procedure is complex and typically requires two to four visits. With advances in technology and materials, one-time root canal therapy is becoming increasingly popular among doctors and patients. Painless treatment is also becoming widely used clinically, making the treatment less painful.

[0003] For example, the machine-used root canal file with a counting function, as disclosed in publication number CN215994316U, comprises a file portion, a handle, and a counting device. The handle of the machine-used root canal file is provided with a counting device and a file portion, and the counting device is provided as a counting ring. However, in actual use, the following deficiencies still exist:

[0004] The above-mentioned machine-used root canal files need to be used in conjunction with a special root canal treatment dental handpiece. When the dental handpiece malfunctions or when more precise root canal cleaning is required manually, the surface of the machine-used root canal files is very smooth and they can easily slip when held directly by hand, causing harm to the patient. In addition, root canal files that break deep in the tooth root often cannot be properly removed, affecting the normal progress of the operation and greatly reducing the practicality and safety of the equipment. Utility Model Content

[0029] As Figures 1-3As shown, the upper end of the file handle 11 is provided with a file handle notch 112 on one side, a limiting hole 111 is formed in the middle of the side wall of the file handle notch 112, and two symmetrical limiting holes 111 are formed in the bottom surface of the file handle notch 112. An annular groove 121 is formed on the surface of the file shank 12. Two guide grooves 132 are respectively formed in the bottom part of the thread groove 133 of the file tip 13. Two guide wires 131 are respectively fixed in the corresponding guide grooves 132. The bottom ends of the two guide wires 131 are fixedly connected with the tip of the file tip 13. The upper ends of the two guide wires 131 are fixedly connected with the bottom of the file shank 12. The two guide wires 131 are made of copper-nickel-titanium alloy material with higher toughness, which can prevent the file tip 13 from breaking in the root of the tooth and being unable to be taken out. The surfaces of the two guide wires 131 are smoothly connected with the bottom of the thread groove 133, which will not cause obstruction to the thread groove 133.

[0030] Among them, the file handle notch 112 is a structure provided with the existing root canal cleaning file, which is convenient to install on the dental handpiece to control rotation. The annular groove 121 has the same effect as disclosed in the application number 202122169399.4, which will not be described in detail here.

[0031] As shown in Figure 1 , Figure 4 , Figure 5 As shown, the inner top surface of the anti-skid sleeve 2 is fixedly connected with the upper ends of two limiting rods 23 respectively. The surfaces of the limiting rods 23 are slidably connected with the two limiting holes 111 formed in the bottom surface of the file handle notch 112, so as to limit the anti-skid sleeve 2. The surface of the anti-skid sleeve 2 is fixedly provided with a plurality of anti-skid vertical lines 22 made of silica gel material, which can enhance the friction to better prevent slipping during manual cleaning.

[0032] The fixing mechanism 21 includes a fixing box 211 fixedly arranged on the top surface of the anti-skid sleeve 2. The fixing rod 214 extends into the limiting hole 111 in the side wall of the file handle notch 112 after penetrating through the inner cavity rear end surface of the fixing box 211. The front end of the fixing rod 214 is fixedly connected with the spring 212. The front end of the spring 212 is fixedly connected with the inner cavity front end surface of the fixing box 211. The spring 212 can return the fixing rod 214 to the original position for next use. The surface of the fixing rod 214 is fixedly connected with the connecting rod 218. The upper end of the connecting rod 218 is fixedly connected with the bottom surface of the sliding block 213. The upper surface of the fixing box 211 is provided with a square groove for the connecting rod 218 to move and pass through. The bottom surface of the sliding block 213 is slidably connected with the top surface of the fixing box 211. The top of the sliding block 213 is provided with a silica gel stripe, which can enhance the friction of the fingers to the sliding block 213. The surface of the fixing rod 214 is fixedly connected with the inner surface of the fixing ring 216. When the fixing ring 216 abuts against the rear end of the inner cavity of the fixing box 211, the fixing rod 214 is at the maximum extension. The front end surface of the fixing rod 214 is provided with a limiting groove 215. The front end of the supporting rod 217 extends into the limiting groove 215, which can provide good support and limiting for the fixing rod 214.

[0033] Principle and process of the utility model:

[0034] When being installed on the dental handpiece for use, firstly, the cleaning file body 1 and the anti-skid sleeve 2 are separated from each other, the sliding block 213 is pushed backward, and the sliding block 213 moves to drive the connecting rod 218, the fixed rod 214 and the fixed ring 216 to move synchronously, so that the fixed rod 214 is completely separated from the limiting hole 111 on the side of the file handle notch 112, the anti-skid sleeve 2 is pulled upward, so that the limiting rod 23 is completely separated from the two limiting holes 111 at the bottom of the file handle notch 112, and the cleaning file body 1 and the anti-skid sleeve 2 are separated from each other, and then the cleaning file body 1 can be installed on the dental handpiece for use.

[0035] When being manually used, firstly, the cleaning file body 1 and the anti-skid sleeve 2 are assembled, the limiting rod 23 in the anti-skid sleeve 2 is aligned with the two limiting holes 111 at the bottom of the file handle notch 112 and is caused to be close to each other, the sliding block 213 on the fixed box 211 is pushed backward by fingers, the sliding block 213 moves backward to drive the connecting rod 218, the fixed rod 214 and the fixed ring 216 to move backward, at this time, the spring 212 is compressed, and the cleaning file body 1 and the anti-skid sleeve 2 are completely attached after being released, at this time, the elastic force of the spring 212 moves the fixed rod 214 into the limiting hole 111 on the side of the file handle notch 112, the limiting rod 23, the fixed rod 214 and the three limiting holes 111 are limited to each other, so that the cleaning file body 1 and the anti-skid sleeve 2 are firmly fixed together, and after assembly, the anti-skid sleeve 2 can be held by fingers to manually clean.

[0036] During the rotating process of the cleaning file, the depth of the current file tip 13 entering can be observed through the annular groove 121 formed on the surface of the file rod 12, the file tip 13 is provided with the guide groove 132 and the corresponding guide wire 131, so that the file tip 13 can be prevented from being broken in the root canal and cannot be taken out, even if the file tip 13 is broken in the middle, the guide wire 131 is still connected with the tip end of the file tip 13, and the guide wire 131 with higher toughness can pull out the broken file tip 13 from the root.
