Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a periodontal pocket depth detection device. Background Art

[0002] In the dental industry, periodontal pocket depth is an important criterion for evaluating gum health. Therefore, pocket depth measurement is an essential step in gum treatment. In the prior art, periodontal pocket depth is generally measured using a purely mechanical periodontal pocket probe. A purely mechanical periodontal pocket probe primarily consists of a handle and a probe. The measurement process is as follows: the doctor holds the handle, inserts the probe into the periodontal pocket, and slowly advances toward the bottom of the pocket. When the probe contacts the bottom of the pocket, the doctor reads the probe, and the pocket depth is measured based on the reading.

[0003] Through long-term monitoring of the depth of periodontal pockets in the entire mouth of a person's teeth, dental health can be effectively assessed. In the prior art, after measuring with a mechanical periodontal pocket probe, it is necessary to write down the data one by one with pen and paper in order to record the corresponding conditions of each periodontal pocket; when it is necessary to provide an examination report for the patient, it is necessary to further input the data recorded on pen and paper into the PC one by one to form an examination report. Therefore, the mechanical periodontal pocket probe in the prior art can meet the most basic measurement functions, but cannot directly obtain electronic measurement data. Doctors need to repeatedly count and input the data into the PC to obtain electronic measurement data, which has the disadvantages of being inconvenient to record measurement data and inconvenient to obtain electronic measurement data.

[0026] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] The terms "first", "second" and the like in the specification, claims and drawings of the present invention are used to distinguish different objects rather than to describe a specific order.

[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] The embodiment of the present invention discloses a periodontal pocket depth detection device, such as Figures 1 to 3 As shown, it includes a transmission assembly and a housing 100,

[0030] The transmission assembly includes a metal probe 210, a slider 220, and a transmission shaft 230, which are arranged from left to right. The metal probe 210 is arranged outside the housing 100, and the slider 220 and the transmission shaft 230 are arranged inside the housing 100. When the other end of the metal probe 210 contacts the user's gums and is subjected to pressure, one end of the metal probe 210 drives the slider 220 to slide to the right through the pull line 240, thereby causing the transmission shaft 230 to move to the right.

[0031] A distance sensor 250 and a signal output module 260 electrically connected to the distance sensor 250 are also provided inside the shell 100, wherein the distance sensor 250 is located on the right side of the transmission assembly and is used to detect the distance that the transmission shaft 230 moves to the right, and the signal output module 260 is used to output an electrical signal representing the distance to an external device.

[0032] In this embodiment of the present invention, the transmission assembly is used to bring metal probe 210 into contact with the user's gums and measure the periodontal pocket depth, which is expressed through the displacement of transmission shaft 230. Specifically, when the other end of metal probe 210 contacts the user's gums and is subjected to pressure, one end of metal probe 210, via pull line 240, drives slider 220 to slide rightward, thereby causing transmission shaft 230 to move rightward.

[0033] In this embodiment of the present invention, distance sensor 250 detects the distance traveled by drive shaft 230 to the right, while signal output module 260 outputs an electrical signal representing this distance (i.e., an electrical signal representing the periodontal pocket depth) to an external device. Optionally, signal output module 260 can be electrically connected to a PC, a display, or a storage device, allowing the periodontal pocket depth to be recorded on the PC, displayed on the display, or stored in a storage device.

[0034] It can be seen that the periodontal pocket depth detection device disclosed in the embodiment of the present invention can determine the periodontal pocket depth by detecting the distance that the transmission shaft 230 in the transmission assembly moves to the right, and transmit the periodontal pocket depth to an external device in the form of an electrical signal through the signal output module 260. This is conducive to efficiently recording the data on the periodontal pocket depth, thereby helping to improve the efficiency of medical staff in detecting the periodontal pocket depth of patients.

[0035] In some specific embodiments of the present invention, Figures 1 to 3 As shown, one end of the pull wire 240 extending to the left to the outside of the housing 100 is tied and connected to one end of the metal probe 210, the rightward extension of the pull wire 240 is sleeved on the left end surface of the slider 220, and the other end of the pull wire 240 is fixedly connected to the inner side surface of the housing 100;

[0036] The right end surface of the slider 220 is in contact with the left end surface of the transmission shaft 230 .

[0037] It can be seen that in this embodiment, the connection relationship between the metal probe 210, the traction line 240, the slider 220 and the transmission shaft 230 in the transmission assembly is conducive to the efficient transmission of the thrust exerted on the end of the metal probe 210 that contacts the user's gums in the transmission assembly. When the other end of the metal probe 210 contacts the user's gums and is subjected to pressure, one end of the metal probe 210 drives the slider 220 to slide to the right through the traction line 240, thereby causing the transmission shaft 230 to move to the right.

[0038] Furthermore, the transmission assembly further includes a spring 270 disposed inside the housing 100. The spring 270 is sleeved on the right side of the transmission shaft 230. A first boss portion 231 is provided in the middle of the transmission shaft 230. The right end surface of the first boss portion 231 is abutted against one end of the spring 270.

[0039] Furthermore, a second boss portion 101 is provided on the right side of the housing 100, and the left end surface of the second boss portion 101 is in contact with the other end of the spring 270.

[0040] When the other end of the metal probe 210 contacts the user's gums and is subjected to pressure, one end of the metal probe 210 drives the slider 220 to slide to the right through the traction line 240, thereby causing the transmission shaft 230 to move to the right, and further causing the spring 270 to be in a compressed state.

[0041] By setting the spring 270, when the transmission shaft 230 moves to the right, the spring 270 is in a compressed state, and can provide a leftward elastic force to the transmission shaft 230. On the one hand, this can limit the contact between the metal probe 210 and the user's gums, and the sampling force for periodontal depth sampling is the instantaneous elastic force of the spring 270 from the initial state to the compressed state. On the other hand, the compression stroke of the spring 270 can be used as the maximum stroke of the transmission shaft 230 moving to the right, thereby playing a limiting role in the process of the transmission shaft 230 moving to the right.

[0042] The first boss portion 231 and the second boss portion 101 are provided to fix the spring 270 inside the housing 100. Optionally, the positions of the first limiting surface 271 and the second limiting surface 272 of the spring 270 can be as follows: Figure 6 shown.

[0043] Furthermore, if Figure 4 As shown, the left end face of the second boss portion 101 is provided with a groove 1011, and one end of the spring 270 facing the second boss portion 101 is engaged in the groove 1011. The provision of the groove 1011 on the second boss portion 101 facilitates the installation and fixation of the spring 270. Optionally, the length between the second boss portion 101 and the right end of the transmission shaft 230 may be less than the original length of the spring 270, so that the spring 270 is always in a compressed state during use; further optionally, the force exerted by the spring 270 on the transmission shaft 230 may be adjusted by adjusting the original length of the spring 270 and the length between the second boss portion 101 and the right end of the transmission shaft 230; further optionally, the force may be adjusted to about 15g. Further, as Figure 2 As shown in FIG3 , a ring portion 211 is provided at one end of the metal probe 210 , and one end of the pulling wire 240 extending to the left to the outside of the shell is tied to the ring portion 211 .

[0044] Providing the annular portion 211 on the metal probe 210 facilitates the connection and installation of the pull line 240 and the metal probe 210 , thereby facilitating the assembly and disassembly of the pull line 240 and the metal probe 210 during daily maintenance, as well as replacement of replacement parts.

[0045] In other specific embodiments of the present invention, Figure 1 Shown and Figure 5 As shown, the housing 100 includes a housing body 120 and a housing head 110 sleeved on the left end of the housing body 120 . The housing head 110 can rotate 360° relative to the housing body 120 .

[0046] By providing a shell head connected to the shell body 120 in a 360° rotation, the metal probe 210 can contact the user's gums at different angles during use of the periodontal pocket depth detection device, which is beneficial to further improve the efficiency of periodontal pocket depth detection.

[0047] Furthermore, the shell body 120 and the shell head 110 are detachably connected. Optionally, the shell head 110 and the metal probe 210 can be treated as a whole and replaced before each use. This helps reduce the risk of cross-infection caused by repeated use of the metal probe 210, thereby helping to improve the safety of use of the detection device.

[0048] In some further specific embodiments of the present invention, an AD conversion module electrically connected to the distance sensor is further provided inside the housing, and the AD conversion module is used to convert an electrical signal input by the distance sensor.

[0049] By setting up the AD conversion module, it is beneficial to perform AD conversion on the electrical signal input by the distance sensor, thereby increasing the efficiency of the signal output module in outputting relevant signals to the external device.

[0050] Further, such as Figures 1 to 3 As shown, the signal output module 260 includes a USB interface 261 , and the electrical signal converted by the AD conversion module is outputted by the USB interface 261 .

[0051] By setting up a USB interface 261, the signal output module 260 can output the electrical signal converted by the AD conversion module to the external device based on the USB communication protocol. Among them, the USB interface 261 is commonly used on PC terminals and display screens, which is conducive to the convenience of using the periodontal pocket depth detection device on PC terminals, display screens and other devices.

[0052] Finally, it should be noted that the periodontal pocket depth detection device disclosed in the embodiment of the present invention is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiment, a person skilled in the art should understand that the technical solution described in the aforementioned embodiment can still be modified, or some of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the spirit and scope of the technical solution of the embodiment of the present invention.
