Description

Technical Field

[0001] This utility model relates to the field of laser working tip technology, and in particular to a working tip telescopic mechanism and a handle. Background Technology

[0002] Dental laser working tips are an important component of dental laser treatment devices, and their design and function are crucial to the treatment effect. Fine working tips: These working tips are designed to be very fine and long, and can reach into the narrow gaps between teeth. They are especially suitable for cleaning plaque and tartar in the gaps between teeth. Their fine tips can accurately remove dirt hidden deep in the gaps between teeth without damaging the gums, ensuring thorough oral cleaning.

[0003] Flat working tip: This type of working tip has a relatively large contact area, making it suitable for removing large areas of tartar and stains from the tooth surface. Its flat design makes the cleaning process more efficient, especially suitable for relatively flat areas of the tooth surface. It can quickly and evenly remove tartar and restore the natural luster of the teeth.

[0027] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] Reference Figure 1-5 This utility model embodiment provides a working tip telescopic mechanism and a handle, which includes: a laser handle 1, a rotating column 2, an internal telescopic threaded column 3, and a working tip assembly 4. The laser handle 1 includes a telescopic working head 101, a rear connecting end 102, an annular groove 103, and a hollow slide rod 104. The front end of the laser handle 1 is fixedly connected to the telescopic working head 101, which can extend and retract to drive other devices to move. An annular groove 103 is provided on the top of the telescopic working head 101, and a hollow slide rod 104 is fixedly connected on the top of the telescopic working head 101. The hollow slide rod 104 can limit the rotation column 2.

[0029] The rotating column 2 includes anti-slip texture 201, bottom rotating groove 202, and internal thread 203. The anti-slip texture 201 is provided on the outer surface of the rotating column 2, and the bottom rotating groove 202 is provided at the bottom of the rotating column 2. The rotating column 2 has a groove inside, and the inner wall of the groove is provided with internal thread 203. When the operator rotates the rotating column 2, the bottom rotating groove 202 rotates on the annular sliding groove 103, and rotates in conjunction with the rotating column 2.

[0030] The internal telescopic threaded column 3 includes a scale groove 301, a scale mark 302, a mounting groove 303, and a limiting hole 304. The scale groove 301 is provided on one side of the internal telescopic threaded column 3, and the scale mark 302 is provided on the scale groove 301. The mounting groove 303 is provided on the top of the internal telescopic threaded column 3, and the limiting hole 304 is provided in the middle of the mounting groove 303. When the rotating column 2 rotates, the rotating column 2 drives the internal telescopic threaded column 3 to move up and down. The scale mark 302 on the scale groove 301 can tell the medical staff the length of the displacement, thus improving accuracy.

[0031] The hollow slide rod 104 passes through the rotating column 2 upwards, and the internal telescopic threaded column 3 is slidably connected to the hollow slide rod 104 through the limiting hole 304. The hollow slide rod 104 can limit the internal telescopic threaded column 3 to prevent it from deviating, and there is a limiting block below the internal telescopic threaded column 3 to prevent it from falling off due to excessive extension and contraction.

[0032] The working tip assembly 4 includes a fixing groove 401, a working tip 402, a working tip connecting block 403, a support sleeve 404, a first sealing groove 405, and a second sealing groove 406. The working tip assembly 4 is fixedly connected to the mounting groove 303. The working tip assembly 4 is a laser concentrator for laser treatment of the patient's affected area. The laser is concentrated inside the working tip assembly 4 and emitted through the working tip 402 on the working tip assembly 4. The working tip assembly connecting block 403 is fixedly connected to the top of the working tip assembly 4, and a fixing groove 4 is formed in the middle of the working tip assembly connecting block 403. 01. The fixing groove 401 on the working tip connecting block 403 can install the working tip 402. The support sleeve 404 is fixedly connected inside the fixing groove 401. The working tip 402 is fixedly connected inside the support sleeve 404. The support sleeve 404 can protect the working tip 402 and fix the working tip 402 in the fixing groove 401. A first sealing groove 405 is opened in the middle of the support sleeve 404. A second sealing groove 406 is opened at one end below the first sealing groove 405. The first sealing groove 405 and the second sealing groove 406 are slots for installing sealing rings.

[0033] A first sealing ring 407 and a second sealing ring 408 are fitted on the first sealing groove 405 and the second sealing groove 406, respectively, to enhance the sealing between the support sleeve 404 and the fixing groove 401.

[0034] An internal telescopic threaded post 3 is fitted on the internal thread 203, and a rotating post 2 is rotatably connected to the annular slide groove 103. By rotating the internal thread 203, the internal telescopic threaded post 3 moves up and down in cooperation with the internal thread 203, and the rotating post 2 rotates on the annular slide groove 103.

[0035] The rear end of the laser handle 1 is fixedly connected to the rear connection end 102, which is fixedly connected to the laser emitting device. The laser emitting device will transmit the laser through the laser handle 1 to the working tip assembly 4 to start the operation.

[0036] The working tip 402 on the working tip assembly 4 is either flat or pointed. The working tip 402 is made of sapphire. The flat-chistle-shaped working tip makes it easier for medical staff to insert the working tip assembly 4 into the patient's periodontal pocket. The pointed working tip reduces light scattering, and the laser energy is concentrated in a very small area, resulting in extremely high power density. The laser can more easily reach deep targets. Sapphire material has good light transmittance.

[0037] Working principle: When using this device, medical staff first need to remove the working tip assembly 4 from the storage device. After removing the working tip assembly 4, they use tweezers to install it into the retractable working head 101 on the laser handle 1. The working tip assembly 4 adopts a flat chisel-shaped working tip assembly. This structure allows medical staff to easily insert the working tip assembly into the patient's periodontal pocket, facilitating treatment of the affected area. The first sealing ring 407 and the second sealing ring 408 on the support sleeve 404 can increase the sealing between the support sleeve 404 and the fixing groove 401. After installation, when medical staff need to adjust the length of the working tip assembly 4, they rotate the rotating column 2. The bottom rotating groove 202 rotates on the annular slide groove 103, cooperating with the rotation of the rotating column 2. The rotating column 2 drives the internal telescopic threaded column 3 to move up and down. The scale mark 302 on the scale groove 301 can help the staff to accurately adjust the position and improve the accuracy of the operation.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
