Description

Technical Field

[0001] This utility model relates to a surgical instrument, and more particularly to a periodontal probe used in oral diagnosis and treatment. Background Technology

[0002] Periodontal probing is the most important method in the diagnosis of periodontitis. Its main purpose is to determine the presence of periodontal pockets or attachment loss, to detect their depth and attachment level, to observe for bleeding after probing, to detect the amount and distribution of subgingival calculus, and to assess root furcation involvement. Currently, the instrument used for periodontal probing is the periodontal probe. During probing, the probe is moved using an adjacent tooth as a fulcrum, employing a lifting and thrusting motion to measure the depth from the gingival margin to the bottom of the pocket. During probing, it should be as close to the tooth surface as possible to reach the bottom; to reduce pain, the pressure should be very light.

[0003] For standard 0.5mm probes, the pressure used in periodontal probing is generally controlled at 20-25g. Because periodontal probing requires a very precise pressure range, clinicians currently rely on experience and feel to control the pressure, which can easily lead to errors. If the pressure is too low, the probe cannot reach the bottom of the periodontal pocket; if the pressure is too high, it can easily puncture the gum.

[0004] Therefore, the purpose of this application is to improve the existing periodontal probe by providing real-time prompts to indicate the range of probing force, so as to ensure that the probing force is always controlled within an appropriate pressure range. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of difficulty in controlling the force during periodontal probing and the easy occurrence of deviations in clinical diagnosis and treatment. It provides real-time prompts to indicate the force used in periodontal probing, so as to ensure that the probing force is always controlled within an appropriate pressure range.

[0006] The periodontal probe of this utility model is characterized in that: the periodontal probe 100 includes a detection mechanism 1, a pressure measuring device 2, and a handle 3;

[0007] A. The detection mechanism 1 is located at the distal end of the handle 3;

[0008] B. The pressure measuring device 2 includes a pressure detection probe 21 and a pressure prompting mechanism 22; the pressure detection probe 21 is disposed on the working part 11 of the detection mechanism 1, and the pressure prompting mechanism 22 is disposed on the handle 3. The pressure applied to the gingiva by the working part 11 is detected by the pressure detection probe 21 and then prompted in real time on the pressure prompting mechanism 22.

[0009] The periodontal probe of this invention detects the force applied to the working part 11 through the pressure measuring device 2, and provides real-time prompts through pressure value prompts, and / or pressure range prompts, and / or pressure status prompts, so as to ensure that the probing force applied by the probing personnel in clinical applications is always controlled within a suitable pressure range. This ensures that the working part 11 can probe the bottom of the periodontal pocket without puncturing the gum due to excessive force, thus ensuring the effectiveness and safety of clinical examination.

[0010] The pressure measuring device 2 is a mechanical pressure measuring device 2-1; the mechanical pressure measuring device 2-1 includes a pressure detection probe 21, a pressure indication mechanism 22, and a pressure transmission mechanism 23. Because this mechanical pressure measurement method utilizes mechanical transmission throughout, it allows for the use of high-temperature, high-pressure sterilization methods most commonly used in dental clinics for disinfection and sterilization.

[0011] The pressure detection probe 21 is a mechanical pressure detection probe 21-1, and the pressure indication mechanism 22 is a mechanical pressure gauge 22-1. The pressure applied to the gingiva by the working part 11 is transmitted to the mechanical pressure detection probe 21-1 and then driven by the pressure transmission mechanism 23 to the pointer 22-11 of the mechanical pressure gauge 22-1. The pointer 22-11 displays the detected pressure. The mechanical pressure detection probe 21-1 and the working part can be manufactured as a whole or manufactured separately and then fixedly connected together.

[0012] The pressure transmission mechanism 23 is a gear-driven pressure transmission mechanism 23-1. Gear-driven transmission is the most common method of force transmission. Through the meshing rotation between gears, the direction of force transmission can be changed and transmitted at different angles, which can very conveniently realize force transmission in curved pipes.

[0013] The gear-driven pressure transmission mechanism 23-1 includes a drive rod 23-11, a transmission rack 23-12, and an output gear 23-13; the output gear 23-13 is connected to the pointer 22-11 and drives the pointer 22-11 to rotate to indicate pressure.

[0014] The transmission rack 23-12 and the output gear 23-13, through their different meshing angles, can achieve the conversion of force transmission at various angles. The output gear 23-13, through the rotation of the shaft 23-13-1, can drive the rotation of the pointer 22-11, thereby indicating the pressure value.

[0015] The pressure measuring device 2 is also equipped with a reset mechanism 24. The reset mechanism 24 can automatically reset the pressure indication mechanism 22 to zero after the external force is removed, so as to facilitate the probing operation again.

[0016] The reset mechanism 24 is a reset spring 24-1. During the probe, the reset spring 24-1 is compressed, and the drive rod 23-11 transmits the force to the pressure indication mechanism 22 for pressure indication. When the probe ends, the pressure applied to the working part 11 is released, and the reset spring 24-1 returns to its original position under the action of elastic force, driving the pressure detection probe 21 back to its original position. The pressure indication mechanism 22 then automatically resets to zero. This spring structure is very simple, and the reset process is very convenient.

[0017] The pressure indication mechanism 22 is a pressure safety range indication mechanism 22-2; the pressure safety range indication mechanism 22-2 includes an indicator block 22-21 and a display window 22-22. The pressure applied to the gingiva by the working part 11 is transmitted to the mechanical pressure detection probe 21-1 and then driven by the pressure transmission mechanism 23 to slide the indicator block 22-21, which is then displayed in the display window 22-22.

[0018] The indicator blocks 22-21 are divided into three areas based on the applied force: insufficient force, appropriate force, and excessive force, identified by different colors and / or different shapes and patterns. The distal end of the mechanical pressure detection probe 21-1 is rigidly connected to the working part 11 or integrally manufactured therein, while the proximal end is connected to the indicator blocks 22-21 via the pressure transmission mechanism 23, typically a rigid transmission mechanism such as the drive rod 23-11. During periodontal probing, under pressure, the working part 11 drives the drive rod 23-11, which in turn moves the indicator blocks 22-21 back and forth. When the display window 22-22 shows an area with insufficient force, it indicates that the probing force needs to be increased; when it shows an area with excessive force, it indicates that the probing force is too strong and needs to be reduced; and when it shows an area with appropriate force, it indicates that the probing force is sufficient to complete the probing process. This area recognition method eliminates the need to constantly monitor the displayed pressure value during probing to determine if the pressure is appropriate. Instead, it allows for easy identification of the probing intensity through simple color or pattern recognition. This provides crucial guidance for probing physicians, especially those without experience. Furthermore, because it eliminates the need for precise identification of the probing pressure value, it minimizes interference with the physician's normal probing process, making it clinically significant for ensuring the continuity of the probing procedure.

[0019] The pressure measuring device 2 is an electric pressure measuring device 2-2. The electric pressure measurement method allows for a very accurate and intuitive digital display of the probing pressure, making clinical observation very convenient.

[0020] The electric pressure measuring device 2-2 includes a pressure detection probe 21, a pressure indication mechanism 22, and a signal processing mechanism 25. The pressure indication mechanism 22 is a digital pressure gauge 22-3. The pressure signal detected by the pressure detection probe 21 is converted into an electrical signal by the signal processing mechanism 25 and then directly displayed digitally on the digital pressure gauge 22-3.

[0021] The pressure detection probe 21 is a sensing diaphragm 21-2.

[0022] The diaphragm sensor design allows for miniaturized structure design and enables precise acquisition and measurement of minute pressures. The electric pressure measuring device 2-2 also includes a power supply 27 and a circuit system 28. The pressure detection probe 21, the pressure indication mechanism 22, and the signal processing mechanism 25 are connected together via the circuit system 28 and the power supply 27.

[0023] The force applied by the working part 11 is collected by the sensing diaphragm 21-2, transmitted through the circuit system 28 to the signal processing mechanism 25 for processing, and then the pressure value is displayed in real time and accurately on the digital pressure gauge 22-3.

[0024] The tip of the working part 11 is a smooth spherical or arc-shaped structure. The tip of the working part 11 is a blunt-tipped design, usually a smooth spherical or arc-shaped structure. This blunt-tipped design makes it less likely for the working part 11 to puncture the gums and cause accidental damage when it enters the periodontal pocket.

[0025] The working part 11 is provided with a marking mechanism 11-1. In order to detect the depth of the periodontal pocket, the marking mechanism 11-1 is provided at the distal end of the working part 11 to detect the depth of the periodontal pocket.

[0026] The marking mechanism 11-1 is a periodontal depth scale 11-11. The marking mechanism 11-1 is usually a periodontal depth scale 11-11 marked in millimeters, which can intuitively display the depth of the periodontal pocket.

[0027] The pressure measuring device 2 is also provided with a calibration mechanism 26. The calibration mechanism 26 can calibrate the position of the zero scale of the pressure indication mechanism 22 to ensure that the pressure measuring device 2 can correctly measure and display the force applied by the working part 11.

[0028] This utility model's periodontal probe includes a detection mechanism 1, a pressure measuring device 2, and a handle 3. The detection mechanism 1 is located at the distal end of the handle 3; the pressure measuring device 2 includes a pressure detection probe 21 and a pressure indication mechanism 22; the pressure detection probe 21 is located at the proximal end of the working part 11 of the detection mechanism 1, and the pressure indication mechanism 22 is located on the handle 3. The pressure applied to the gingiva by the working part 11 is detected by the pressure detection probe 21 and then indicated in real time by the pressure indication mechanism 22. This utility model's periodontal probe, after detecting the force applied to the working part 11 by the pressure measuring device 2, provides real-time indication through pressure value indication, and / or pressure range indication, and / or pressure status indication, to ensure that the probing force applied by the examiner in clinical application is always controlled within an appropriate pressure range. This ensures that the working part 11 can probe the bottom of the periodontal pocket without puncturing the gingiva due to excessive force, thus ensuring the effectiveness and safety of clinical examination.

[0049] Example 1: Periodontal probe of this utility model with mechanical pressure measuring device including pressure gauge

[0050] refer to Figures 1 to 1-6 The periodontal probe in this embodiment includes a detection mechanism 1, a pressure measuring device 2, and a handle 3.

[0051] The tip of the working part 11 is a smooth spherical or arc-shaped structure. The tip of the working part 11 is a blunt-tipped design, usually a smooth spherical or arc-shaped structure. This blunt-tipped design makes it less likely for the working part 11 to puncture the gums and cause accidental damage when it enters the periodontal pocket.

[0052] The working part 11 is provided with a marking mechanism 11-1. In order to detect the depth of the periodontal pocket, the marking mechanism 11-1 is provided at the distal end of the working part 11 to detect the depth of the periodontal pocket.

[0053] refer to Figure 1 and Figure 1-3 The marking mechanism 11-1 is a periodontal depth scale 11-11. The marking mechanism 11-1 is usually a periodontal depth scale 11-11 marked in millimeters, which can intuitively display the depth of the periodontal pocket.

[0054] The detection mechanism 1 is located at the distal end of the handle 3. The pressure measuring device 2 includes a pressure detection probe 21 and a pressure indication mechanism 22; the pressure detection probe 21 is located at the proximal end of the working part 11 of the detection mechanism 1, and the pressure indication mechanism 22 is located on the handle 3. The pressure applied to the gingiva by the working part 11 is detected by the pressure detection probe 21 and then indicated in real time by the pressure indication mechanism 22.

[0055] refer to Figure 1-2 and Figure 1-4 In this embodiment, the pressure measuring device 2 is a mechanical pressure measuring device 2-1 containing a pressure gauge. The mechanical pressure measuring device 2-1 includes a pressure detection probe 21, a pressure indication mechanism 22, and a pressure transmission mechanism 23. Because this mechanical pressure measurement method utilizes mechanical transmission throughout, it allows for the use of high-temperature, high-pressure sterilization methods most commonly used in dental clinics for disinfection and sterilization.

[0056] The pressure detection probe 21 is a mechanical pressure detection probe 21-1, and the pressure indication mechanism 22 is a mechanical pressure gauge 22-1. The pressure applied to the gingiva by the working part 11 is transmitted to the mechanical pressure detection probe 21-1 and then driven by the pressure transmission mechanism 23 to the pointer 22-11 of the mechanical pressure gauge 22-1. The pointer 22-11 displays the detected pressure. In this embodiment, the mechanical pressure detection probe 21-1 and the working part 11 are manufactured as a single unit. In practical applications, the mechanical pressure detection probe 21-1 and the working part 11 can also be manufactured separately and then fixedly connected together.

[0057] In this embodiment, the pressure transmission mechanism 23 is a gear-driven pressure transmission mechanism 23-1. Gear-driven transmission is the most common method of force transmission. Through the meshing rotation between gears, the direction of force transmission can be changed and transmitted at different angles, which can very conveniently realize force transmission in curved pipes.

[0058] refer to Figure 1-2 and Figure 1-4The gear-driven pressure transmission mechanism 23-1 includes a drive rod 23-11, a transmission rack 23-12, and an output gear 23-13. The drive rod 23-11 is connected to the distal end of the transmission rack 23-12, and the proximal end of the transmission rack 23-12 meshes with the output gear 23-13. The output gear 23-13 is connected to the pointer 22-11 via a rotating shaft 23-13-1.

[0059] When a force is applied to the working part 11 for probing, the mechanical pressure detection probe 21-1 drives the drive rod 23-11 to move backward under the drive of the working part 11. The drive rod 23-11 then drives the transmission rack 23-12 to move backward. Through meshing, the output gear 23-13 rotates, which drives the rotating shaft 23-13-1 to rotate, thereby driving the pointer 22-11 to rotate and thus indicating the pressure.

[0060] In this embodiment, the transmission rack 23-12 and the output gear 23-13 achieve a 90° transmission direction conversion to drive the rotation of the pointer 22-11. In practical applications, the transmission rack 23-12 and the output gear 23-13 can achieve the conversion of force transmission at various angles through different meshing angle designs.

[0061] refer to Figure 1-2 and Figure 1-5 The pressure measuring device 2 is also equipped with a reset mechanism 24. The reset mechanism 24 can automatically reset the pressure indication mechanism 22 to zero after the external force is removed, so as to facilitate the probing operation again.

[0062] In this embodiment, the reset mechanism 24 is a reset spring 24-1. The reset spring 24-1 is located at the distal end of the drive rod 23-11 and is limited by the integrally manufactured working part 11 and the mechanical pressure detection probe 21-1. During the probe, the reset spring 24-1 is compressed, and the drive rod 23-11 transmits the force to the pressure indication mechanism 22 for pressure indication. When the probe ends, the pressure applied to the working part 11 is released, and the reset spring 24-1 returns to its original position under the action of elastic force, driving the pressure detection probe 21 back to its original position. Simultaneously, a reset spring 24-1 is also provided at the bottom of the rotating shaft 23-13-1. When the rotating shaft 23-13-1 rotates, the reset spring 24-1 is compressed, and the pointer 22-11 rotates to indicate pressure. When the external force is removed, the reset spring 24-1 returns to its original position, and under the action of elastic restoring force, the pointer 22-11 returns to zero, and the pressure indication mechanism 22 automatically returns to zero. This spring structure is very simple and the reset process is very convenient.

[0063] refer to Figure 1-6 The pressure measuring device 2 is further provided with a calibration mechanism 26. The calibration mechanism 26 calibrates the zero-scale position of the pressure indication mechanism 22 to ensure that the pressure measuring device 2 can correctly measure and display the force applied by the working part 11. In this embodiment, the calibration mechanism 26 is a calibration stud 26-1 located near the end of the drive rod 23-11. Before starting the probe, rotating the working part 11 rotates the drive rod 23-11, which in turn rotates the calibration stud 26-1 to perform zero-position calibration. This rotational calibration method has a very simple structure and is easy to operate.

[0064] The periodontal probe of this invention detects the force applied to the working part 11 via the pressure measuring device 2, and provides real-time feedback via the mechanical pressure gauge 22-1. This ensures that the probing force applied by the examiner during clinical application is always controlled within an appropriate pressure range, guaranteeing that the working part 11 can probe the bottom of the periodontal pocket without puncturing the gingiva due to excessive force, thus ensuring the effectiveness and safety of clinical examination. Moreover, since this mechanical pressure measurement method uses mechanical transmission, it can be sterilized using the high-temperature and high-pressure sterilization methods most commonly used in oral clinical practice.

[0065] Example 2: Periodontal probe of this utility model: a mechanical pressure measuring device with pressure safety range indication.

[0066] refer to Figure 1-7 and Figure 1-8 The difference between this embodiment and embodiment 1 is that in this embodiment, the pressure indication mechanism 22 is a pressure safety range indication mechanism 22-2.

[0067] The pressure safety range indication mechanism 22-2 includes an indicator block 22-21 and a display window 22-22. The pressure applied to the gingiva by the working part 11 is transmitted to the mechanical pressure detection probe 21-1 and then driven by the pressure transmission mechanism 23 to slide the indicator block 22-21, which is then displayed in the display window 22-22.

[0068] The indicator blocks 22-21 are divided into three areas according to the magnitude of the applied force: too little force, appropriate force, and too much force, and are identified by different colors and / or different shapes and patterns.

[0069] The display windows 22-22 are located on the handle 3.

[0070] The distal end of the mechanical pressure detection probe 21-1 is rigidly connected to the working part 11 or integrally manufactured together, and the proximal end is connected to the indicator block 22-21 via the rigid drive rod 23-11. The handle 3 has a sliding groove 31 on its inner side, and the drive rod 23-11 can drive the indicator block 22-21 to move back and forth within the sliding groove 31.

[0071] During periodontal probing, under pressure, the working part 11 drives the drive rod 23-11, which in turn drives the indicator block 22-21 to move back and forth. When the display window 22-22 shows an area with insufficient force, it indicates that the probing force needs to be increased. When the display window 22-22 shows an area with excessive force, it indicates that the probing force is too strong and needs to be reduced. When the display window 22-22 shows an area with appropriate force, it indicates that the probing force is sufficient to effectively complete the probing process.

[0072] In this embodiment, this area recognition method eliminates the need to observe the displayed pressure value in real time during the probing process to determine whether the pressure is appropriate. It only requires simple identification of color or pattern to determine whether the probing intensity is appropriate. This provides very important guidance for probing doctors, especially inexperienced ones. Moreover, since it does not require precise identification of the probing pressure value to determine whether the probing pressure is appropriate, it greatly minimizes interference with the doctor's normal probing process and has significant clinical implications for the continuous conduct of the probing process.

[0073] Example 3: Periodontal probe of this utility model with electric pressure measuring device

[0074] refer to Figures 2 to 2-3 The difference between this embodiment and embodiment 1 is that in this embodiment, the pressure measuring device 2 is an electric pressure measuring device 2-2, which can very accurately display the probing pressure digitally and intuitively, making clinical observation very convenient.

[0075] Referring to Figure 2, the electric pressure measuring device 2-2 includes a pressure detection probe 21, a pressure indication mechanism 22, a signal processing mechanism 25, a power supply 27, and a circuit system 28.

[0076] refer to Figure 2-2 and Figure 2-3 In this embodiment, the pressure detection probe 21 is a sensing diaphragm 21-2. The sensor design of the diaphragm allows for a miniature structure design and enables precise acquisition and measurement of minute pressures.

[0077] refer to Figure 2 and Figure 2-1The pressure indication mechanism 22 is a digital pressure gauge 22-3. The pressure signal detected by the pressure detection probe 21 is converted into an electrical signal by the signal processing mechanism 25 and then directly displayed digitally on the digital pressure gauge 22-3.

[0078] The pressure detection probe 21, the pressure indication mechanism 22, and the signal processing mechanism 25 are connected together via the circuit system 28 and the power supply 27.

[0079] The force applied by the working part 11 is collected by the sensing diaphragm 21-2, transmitted through the circuit system 28 to the signal processing mechanism 25 for processing, and then the pressure value is displayed in real time and accurately on the digital pressure gauge 22-3.

[0080] In this embodiment, the electric pressure measuring device 2-2 can achieve accurate acquisition and measurement of minute pressures through diaphragm pressure acquisition, and display the pressure in real time through digital display. It is very effective for clinical use in measurements with high accuracy requirements.

Although preferred embodiments of this utility model have been described and illustrated herein, those skilled in the art will understand that these embodiments are merely illustrative, and those skilled in the art can make numerous variations, improvements, and substitutions without departing from this utility model.
