Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a universal guide plate for non-invasive monitoring of oral microcirculation. Background Art

[0002] When inflammation occurs in the periodontal or per-implant tissues, the local gingival microcirculation system will undergo a series of significant hemodynamic and microvascular structural changes. Preliminary studies have shown that there is a close relationship between gingival blood perfusion and periodontal health. Microcirculation changes may be an early sign predicting pathological changes in gingival tissue, and gingival blood flow dysfunction may become an important prognostic marker. Therefore, monitoring the blood flow and blood oxygen status in gingival microcirculation is crucial for early identification of periodontal disease or per-implant inflammation.

[0003] Laser Doppler Flowmetry (LDF) is an instrument used to evaluate the blood flow dynamics of the microcirculation system and the changes in local tissue oxygen content. Due to its non-invasiveness and high sensitivity, LDF and measurement instruments with the same principle are important tools for clinically evaluating and monitoring microcirculation changes. The applications of LDF in dentistry include measurement of dental pulp microcirculation and vitality, monitoring of gingival blood flow changes after periodontal surgery to reflect wound healing, exploration of gingival blood flow changes after orthodontic force application, study of the impact of smoking on gingival blood flow changes, and gingival blood flow changes in healthy and diseased states, etc.

[0004] However, all along, how to design a measurement guide plate to fix the measurement position and avoid relative movement between the probe and the tissue during measurement of soft tissues remains a methodological problem to be solved. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art, and provides a universal guide plate for non-invasive monitoring of oral microcirculation, including: A first guide plate body, including a first detection plate configured on the side of the gingiva close to the cheek and a first connecting member configured on the tooth crown, and the first connecting member is provided with a plug-in groove along the radial direction; A second guide plate body, including a second detection plate configured on the side of the gingiva close to the tongue and a second connecting member configured on the tooth crown, and the second connecting member can be plug-in arranged in the plug-in groove; a vertical surface of the first detection plate close to the tooth side, a vertical surface of the second detection plate close to the tooth side, a lower end surface of the first connecting member, and a lower end surface of the second connecting member outside the plug-in groove form an alveolar ridge fixing interval; The probe fixing member is disposed on the first detection plate and the second detection plate. The probe fixing member on the first detection plate / the second detection plate includes a first probe fixing assembly near the first connecting member / the second connecting member side and a second probe fixing assembly away from the first connecting member / the second connecting member side.

[0006] Further, the first detection plate has an arc-shaped structure. The center of the arc-shaped first detection plate is located on the side close to the gum. The upper end surface of the first detection plate extends toward the lingual side to form a first connecting member. The side of the first connecting member that does not connect to the first detection plate is recessed toward the first detection plate to form the insertion slot.

[0007] Further, the second detection plate has an arc-shaped structure. The center of the arc-shaped second detection plate is located on the side close to the tongue. The upper end surface of the second detection plate extends in a direction away from the lingual side to form a second connecting member. The shape and size of the second connecting member match those of the insertion slot.

[0008] Further, the first probe fixing assembly is at least three hollow slots arranged horizontally; the second probe fixing assembly is at least two hollow slots arranged horizontally; the hollow slots in the first probe fixing assembly and the second probe fixing assembly are arranged relatively staggeredly to form a zigzag structure. The shape and size of the hollow slots match those of the probe.

[0009] Further, the depth range of the insertion slot is 5 mm to 16 mm; the width range of the second connecting member is 5 mm to 16 mm.

[0010] Further, the distance from the second probe fixing assembly on the first guide plate body to the first connecting member ranges from 10 mm to 14 mm.

[0011] Further, the distance from the second probe fixing assembly on the second guide plate body to the second connecting member ranges from 12 mm to 16 mm.

[0012] Further, the thicknesses of the first detection plate, the second detection plate, and the second connecting member are all 2 mm.

[0013] Further, the distance from the second probe fixing assembly to the bottom surface of the detection plate where it is located ranges from 1 mm to 2 mm.

[0014] Further, the materials of the first guide plate body and the second guide plate body are both medical plastic materials.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. A general guide plate for non-invasive monitoring of oral microcirculation according to the present invention includes a first guide plate body and a second guide plate body that can be adjusted and inserted, and can adapt to different tooth positions with a large difference in the width of the anterior and posterior tooth crowns. The adjustment range of the present invention is designed to be about 10 - 15 mm, which can meet the measurement requirements of different widths of alveolar ridges. Before measurement, clinicians can try on the general guide plate, adjust the pin structure, confirm the suitable measurement distance and position, and then use silicone rubber to fix the guide plate on the local dentition. This design is not only applicable to a variety of clinical application scenarios, such as the early monitoring of periodontal disease and peri-implant inflammation, but also simplifies the operation process and improves the convenience of clinical use.

[0016] 2. Probe fixing parts are provided on both the first guide plate body and the second guide plate body of a general guide plate for non-invasive monitoring of oral microcirculation according to the present invention. The size of the probe fixing parts is precisely matched with the measurement probe, so as to keep the distance between the probe and the gingiva in a state of light contact without pressure, and the angle is perpendicular to the measurement surface to ensure the accuracy of the measurement results. Clinicians can, according to the specific tooth structure of the patient, adjust the pin structure to individually set the measurement distance and position, and achieve multiple repeated measurements at the same site. This design significantly reduces the human operation error, improves the repeatability of the measurement data, and provides a more accurate microcirculation monitoring means for clinicians.

[0017] 3. The general guide plate for non-invasive monitoring of oral microcirculation according to the present invention is fixed by using a tooth-supported tray in cooperation with a flexible occlusal record or silicone rubber, which causes less irritation to soft tissues and provides higher patient comfort.

[0018] 4. The structure of the general guide plate for non-invasive monitoring of oral microcirculation according to the present invention is simple, and only includes a pluggable guide plate body and a probe fixing part provided on the guide plate body. It is easy to be mass-produced and customized individually, and can be widely applied in clinical practice and scientific research, providing a reliable and repeatable microcirculation monitoring means for the early identification of periodontal disease or peri-implant inflammation.

Detailed implementation manners

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] To make the drawings concise, only the parts related to the present invention are schematically shown in each drawing, and they do not represent their actual structures as products. Additionally, to make the drawings concise and easy to understand, in some drawings, components with the same structure or function are only schematically shown as one of them, or only one of them is labeled. In this article, "one" not only means "only this one" but also can mean "more than one" situation.

[0023] First embodiment Please refer to Figure 1-8, the technical solution of a general guide plate for non-invasive oral microcirculation monitoring provided in this embodiment is as follows: The first guide plate body 1 includes a first detection plate 11 disposed on the side of the gum close to the cheek and a first connecting member 12 disposed on the tooth crown. The first connecting member 12 is provided with a plugging groove 13 in the radial direction. The second guide plate body 2 includes a second detection plate 21 disposed on the side of the gum close to the tongue and a second connecting member 22 disposed on the tooth crown. The second connecting member 22 can be plugged into the plugging groove 13. A dental alveolar ridge fixing interval 5 is formed between the vertical surface of the first detection plate 11 close to the tooth side, the vertical surface of the second detection plate 21 close to the tooth side, the lower end surface of the first connecting member 12, and the lower end surface of the second connecting member 22 outside the plugging groove 13. The probe fixing member 3 is disposed on the first detection plate 11 and the second detection plate 21. The probe fixing member 3 on the first detection plate 11 / the second detection plate 21 includes a first probe fixing assembly 31 close to the first connecting member 12 / the second connecting member 22 and a second probe fixing assembly 32 away from the first connecting member 12 / the second connecting member 22.

[0024] In a specific implementation, as shown in the attached Figure 1 - attached Figure 4 As shown, taking (a) in the attached Figure 1 as an example, the left side is the first guide plate body 1 and the right side is the second guide plate body 2. At this time, the structure shown is that the second connecting member 22 is completely plugged into the plugging groove 13, and the jacks on the first guide plate body 1 and the second guide plate body 2 are the probe fixing member 3. Specifically, in order to conform to the arrangement structure of the dental alveolar ridge, the first detection plate 11 is designed as an arc structure. The center of the arc-shaped first detection plate 11 is located on the side close to the gum. The upper end surface of the first detection plate 11 extends towards the tongue side to form the first connecting member 12. The side of the first connecting member 12 that does not connect to the first detection plate 11 is recessed towards the first detection plate 11 to form the plugging groove 13. The second detection plate 21 is also designed as an arc structure. The center of the arc-shaped second detection plate 21 is located on the side close to the tongue. The upper end surface of the second detection plate 21 extends in the direction away from the tongue side to form the second connecting member 22. The shape and size of the second connecting member 22 match those of the plugging groove 13.

[0025] Specifically, since the crown heights of different patients are different, in order to match the usage requirements of patients with different crown heights, two rows of probe fixing components are designed. The first probe fixing component 31 is at least three hollow grooves arranged horizontally; the second probe fixing component 32 is at least two hollow grooves arranged horizontally; the hollow grooves in the first probe fixing component 31 and the second probe fixing component 32 are arranged in a staggered manner to form a zigzag structure style, and the shape and size of the hollow grooves match the probe 4.

[0026] In a specific implementation, the buccolingual alveolar ridge width of healthy adults is between 5 mm and 16 mm. Therefore, the depth a range of the insertion slot 13 is set to be between 5 mm and 16 mm; the width a range of the second connecting member 22 that matches the insertion slot 13 is also set to be between 5 mm and 16 mm, so as to achieve full coverage of the measurement range. Specifically, the crown height of healthy adults is usually between 6 mm and 12 mm. In addition, about 4 mm of material space needs to be reserved. Therefore, the distance c range from the second probe fixing component 32 on the first guide plate body 1 to the first connecting member 12 is set to be between 10 mm and 14 mm; the distance d range from the second probe fixing component 32 on the second guide plate body 2 to the second connecting member 22 is set to be between 12 mm and 16 mm.

[0027] Specifically, the thickness b of the first detection plate 11, the second detection plate 21, and the second connecting member 22 is 2 mm.

[0028] Specifically, the distance e from the second probe fixing component 32 to the bottom surface of the detection plate where it is located is 1 mm to 2 mm.

[0029] Specifically, the materials of the first guide plate body 1 and the second guide plate body 2 are both medical plastic materials.

[0030] The working principle or working process of a general guide plate for non-invasive monitoring of oral microcirculation provided by the present invention is as follows: When in use, first pre-insert the second connecting member 22 into the insertion slot 13 and then place the general guide plate in the mouth. The stable fitting is achieved by the support of the dental arch. The pin structure automatically adapts to different crowns and alveolar ridge widths to adjust the pin structure. After confirming the suitable measurement distance and position, then use silicone rubber to fix the general guide plate on the local dental arch. Thus, the fixation of the general guide plate is completed. After the fixation is completed, insert the O2C probe into the target hollow groove in the probe fixing member 3, so as to accurately guide the probe to the target gingival area, and then start the device to perform non-invasive, repeated and stable gingival microcirculation measurement. The general guide plate of the same patient can be cleaned, disinfected and reused for repeated measurement within a certain observation period.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
