Description

Technical Field

[0001] This utility model relates to the field of dental surgical instruments, and in particular to an external light source for a root canal probe. Background Technology

[0002] A root canal probe is a dental instrument primarily used during root canal treatment to explore the canal orifice, clear the canal, and determine the canal's orientation and depth. It is typically made of tungsten carbide or stainless steel, with a fine, sharp tip that possesses a degree of flexibility to adapt to the complex anatomy of the root canal. Existing root canal probes, such as the Chinese utility model patent with publication number CN204618447U, disclose a probe including a handle with pressure needles at both ends; the pressure section of the pressure needle has graduations; the tip of the pressure needle has a raised pressure surface; furthermore, the graduations are set to 10mm, 15mm, and 20mm; furthermore, an anti-slip layer is provided on the surface of the handle. When using this type of root canal probe, the patient's oral cavity is illuminated by a dental surgical lamp, and the operator holds the root canal probe to perform the operation. However, during this process, the operator's hand or the main body of the root canal probe can easily block the light from the lamp, affecting the ambient brightness of the probe tip during operation within the root canal. Since the root canal orifice is usually located at the bottom of the pulp chamber, which is deep and difficult for light to reach, the dentist may have difficulty accurately locating the root canal orifice if the light source is blocked, especially if the root canal orifice is small or covered by calcified tissue, affecting the accuracy and safety of the surgery. Utility Model Content

[0003] The purpose of this invention is to provide an external illumination device for root canal probes. This invention has a simple structure, is easy to install, and provides stable illumination for the root canal probe, improving the ambient brightness during probe operation.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0024] Example: An external illumination device for root canal probes, including a connecting sleeve 1 fitted onto one end of the root canal probe, as shown in the attached figure. Figure 1 and 2 As shown, the connecting sleeve mainly fits into the end of the handle of the root canal probe. The outer surface of the connecting sleeve 1 has anti-slip protrusions 7 for anti-slip purposes; this increases friction and improves grip stability when the operator holds the connecting sleeve. The connecting sleeve 1 has an end sleeve 2, the top of which has a conical surface 3 that fits into the tip of the root canal probe. An LED 4 for illuminating the root canal probe is mounted on the conical surface 3. An aperture 5, which works in conjunction with the LED 4, is mounted on the circumferential surface of the end sleeve 2, close to the LED 4, to enhance the light brightness around the probe body, facilitating operation within the root canal. The connecting sleeve can rotate around the root canal probe, aligning the LED with the tip of the probe. The aperture 5 has a ring-shaped structure, with its emitting side facing the probe body. This structure effectively enhances the ambient brightness around the probe, providing stable supplemental lighting for the probe tip during operation within the root canal. The connecting sleeve 1 has an electronic component tube 6 on its circumferential surface for placing batteries and circuit boards, as shown in the attached figure. Figure 3 As shown, the LED bead 4 is connected to the circuit board inside the electronic component tube 6 via a circuit. The bottom inner side of the connecting sleeve 1 has an annular bevel 11, which facilitates the connecting sleeve being fitted onto the handle of the root canal probe. The electronic component tube 6 and the connecting sleeve 1 are an integral structure, and the electronic component tube 6 and the connecting sleeve are manufactured as a single piece, which ensures good structural strength.

[0025] The electronic component tube 6 is divided by a sheet into a first chamber 8 for placing a circuit board and a second chamber 9 for placing a button battery compartment 13, as shown in the attached diagram. Figure 4 and 5 As shown, a button battery is installed in the button battery compartment; a switch 12 for the LED is installed on the side of the connecting sleeve, and the switch 12 is connected to the circuit board in the first chamber. The switch 12 can control the LED to turn on or off. The LED, the aperture, and the switch are all connected to the circuit board via wiring. The button battery supplies power to the circuit board, and pressing the switch turns on the LED and the aperture. A rubber cover 10 is installed at the port of the electronic component tube 6. The rubber cover 10 includes a main body 101 for setting the port of the electronic component tube 6, as shown in the attached figure. Figure 6 As shown, the upper end of the main body 101 has an outer sealing end 102, and the lower end of the main body 101 has an inner sealing end 103. An annular groove 104 is formed between the inner sealing end 103 and the outer sealing end 102, which fits with the port of the electronic component tube 6. The electronic component tube is sealed by a rubber cap, thus sealing the second chamber and providing a certain degree of sealing protection for the button battery. The edge of the outer sealing end 102 has an extension tab 105 for easy removal of the rubber cap 10. The rubber cap fits tightly with the port of the electronic component tube, and it is inconvenient to remove the rubber cap without using a tool. Therefore, an extension tab is provided on the edge of the outer sealing end, which allows the rubber cap to be pulled out. The connecting sleeve 1 has a stabilizing anti-slip member 14 between its open end and the handle of the root canal probe. This stabilizing anti-slip member ensures a secure connection between the connecting sleeve and the handle of the root canal probe, preventing slippage when the connecting sleeve is fitted onto the root canal probe. The stabilizing anti-slip member 14 includes an inner ring 141 and an outer ring 142, as shown in the attached figure. Figure 7 As shown, the inner ring is embedded between the connecting sleeve and the handle of the root canal probe, and the outer ring is on the outside of the connecting sleeve. The entire stabilizing and anti-slip component can be easily removed through the connecting sleeve.

[0026] The working principle of this invention is as follows: The connecting sleeve and the end sleeve are fitted onto the working end of the root canal probe. The conical surface of the end sleeve fits into the tip of the root canal probe. When the LED and the aperture are turned on, the light generated by the aperture and the LED illuminates the probe body, providing a stable supplemental lighting effect and improving the ambient brightness during root canal probe operation. After installing this invention on a conventional root canal probe, the light source of this invention can illuminate the inside of the root canal, helping dentists to clearly see the direction and curvature of the root canal, as well as the presence of lateral root canals or calcification, making it easier to detect hidden problems such as tiny lesions and calcified areas within the root canal. Furthermore, this invention has a simple structure and is very convenient to install on a root canal probe.

Furthermore, in these embodiments, "up," "down," "left," "right," "front," and "back" represent relative positions only, not absolute positions. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
