[0001] The utility model relates to the technical field of switching structures, in particular to a dental needle free switching structure. Background Art

[0002] Periodontal probe examination is an oral examination method that uses a special probe tool to evaluate the health of the tissues around the teeth. Its main functions include detecting the depth of periodontal pockets, evaluating the level of gingival attachment, detecting gingival bleeding, discovering periodontal lesions, and monitoring the progression of the disease. Periodontal probe examination helps to detect problems in the early stages of the disease, take timely treatment measures, and formulate corresponding treatment plans based on the examination results. It is an important part of routine oral examinations.

[0003] During periodontal probing, a dedicated periodontal probe is often used for examination. During probing, different structures of probes are constantly switched and used probes are placed together with unused probes. Doctors need to constantly pick up probes, which can easily cause the probes to shift when they are picked up, and easily contact unused probes, which can lead to the risk of cross infection. Therefore, we propose a free-switching structure for dental burs. Summary of the invention

[0029] Example

[0030] like Figure 1-4 As shown, a dental needle free switching structure proposed by the utility model includes a shell 1, and also includes a rotating base 2 rotatably installed on the top of the shell 1, a plurality of needle rods 5 are provided at the bottom of the rotating base 2, and needles are fixedly installed at the bottom of the needle rods 5. The needles can be set to different models. A through hole 101 for the needle rod 5 to pass through is opened on one side of the bottom of the shell 1, and a bearing seat for the rotating base 2 to rotate is provided on the top of the shell 1.

[0031] Among them, a containing bottle 6 for containing alcohol is fixedly installed at the bottom of the shell 1, and a cleaning sponge 7 is provided on the outer side of the bottom end of the containing bottle 6. The cleaning sponge 7 abuts against the needle head at the bottom of the needle rod 5. A round hole is opened at the bottom of the containing bottle 6 for alcohol to flow out. When the rotating seat 2 is rotated, the needle rod 5 rotates in the shell 1. Since the cleaning sponge 7 is soaked by the alcohol in the containing bottle 6, the cleaning sponge 7 abutting against the needle head cleans and disinfects the needle head, avoiding cross infection, thereby improving the safety and convenience of using the device.

[0032] In this embodiment, the needle bar 5 is slidably installed in the outer shell 1, and a pressure rod 8 for controlling the movement of the needle bar 5 is provided on the rotating seat 2. A round rod 9 is fixedly installed on the end of the needle bar 5 extending into the rotating seat 2, and the pressure rod 8 is fixedly installed on the top of the round rod 9. A connecting rod 4 is fixedly installed on the end of the pressure rod 8 away from the rotating seat 2, and a first buckle 13 is fixedly installed on the other end of the pressure rod 8. After rotating the rotating seat 2 to align the connecting rod 4 corresponding to the needle bar 5 to be used with the through hole at the bottom of the outer shell 1, press the corresponding pressure rod 8 to move the round rod 9 downward, driving the needle bar 5 to move downward until the needle head at the bottom of the needle bar 5 is exposed outside the through hole 101.

[0033] Among them, the rotating seat 2 is provided with a slide groove 201 for the pressure rod 8 to move, and the top of the round rod 9 is fixedly installed with a limit block, which is used to prevent the round rod 9 from sliding into the shell 1. The limit block is fixedly connected to the bottom of the rotating seat 2 with a first spring 10. The bottom of the rotating seat 2 is hinged with multiple second buckles 14 that are adapted to the shape of the first buckle 13. When the first buckle 13 moves downward, it engages with the second buckle 14, so that the needle rod 5 is kept in a fixed state with the needle tip at the bottom exposed outside the through hole 101 for use. It is achieved that the corresponding needle tip can be extended out of the shell 1 for use by simply rotating the rotating seat 2 and pressing the pressure rod 8, avoiding the operation of medical staff repeatedly taking the probe, and the structure is simple and easy to use.

[0034] In this embodiment, the reset assembly includes a pull block 3 slidably installed on the top of the rotating seat 2, and the reset assembly also includes a sleeve 11 fixedly installed at the bottom center of the rotating seat 2, and a moving rod 12 is slidably installed in the sleeve 11. The pull block 3 is fixedly installed on the top of the moving rod 12. A round cover is provided on the top of the rotating seat 2, and a round hole is opened on the round cover for the moving rod 12 to pass through. The pull block 3 is pulled to make the moving rod 12 move in the sleeve 11, driving the support rod 15 to swing, so that the second buckle 14 swings toward the side close to the corresponding round rod 9, so that the first buckle 13 is disengaged from the second buckle 14. Under the action of the first spring 10, the round rod 9 moves upward, and the pressure rod 8 is reset.

[0035] Among them, a second spring 16 is fixedly connected between the bottom of the moving rod 12 and the bottom of the sleeve 11, and multiple groups of support rods 15 are hinged on the moving rod 12. The other end of the support rod 15 is fixedly connected to the second buckle 14. The sleeve 11 is provided with multiple rectangular holes for the support rods 15 to pass through. The pull block 3 is released, and under the action of the second spring 16, the moving rod 12 moves downward, thereby realizing the reset of the moving rod 12 and the pull block 3.

[0036] Working principle: During the working process of the utility model, first rotate the rotating seat 2 to align the connecting rod 4 corresponding to the needle rod 5 to be used with the through hole at the bottom of the shell 1, then press the corresponding pressing rod 8 to move the round rod 9 downward, so that the corresponding needle rod 5 fixedly connected to the round rod 9 moves downward until the needle head at the bottom of the needle rod 5 is exposed outside the through hole 101. At this time, the first buckle 13 fixedly installed at one end of the pressing rod 8 moves downward and engages with the second buckle 14, so that the needle rod 5 is kept in a fixed state with the needle head at the bottom exposed outside the through hole 101 for use. When other needle heads need to be used, pull the pull block 3 to move the moving rod 12 fixedly installed at the bottom of the pull block 3 in the sleeve 11, driving the support hinged between the moving rod 12. The rod 15 swings, driving the second buckle 14 fixedly connected to the support rod 15 to swing toward the side close to the corresponding round rod 9, so that the first buckle 13 is disengaged from the second buckle 14. Under the action of the first spring 10, the round rod 9 moves upward, realizing the resetting of the pressure rod 8, and realizing that the corresponding needle tip can be extended out of the shell 1 for use by simply rotating the rotating seat 2 and pressing the pressure rod 8, thereby avoiding the medical staff from repeatedly taking the probe. The structure is simple and easy to use; in addition, while rotating the rotating seat 2, the needle rod 5 rotates in the shell 1, and since the cleaning sponge 7 is soaked by the alcohol in the bottle 6, the cleaning sponge 7 abutting against the needle tip cleans and disinfects the needle tip, avoiding cross infection, thereby improving the safety and convenience of the device.

[0037] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
