Technical Field

[0001] This invention belongs to the field of quantitative measurement tools, specifically relating to a pen for assessing the degree of tooth loosening. Background Technology

[0002] In the field of oral medicine, accurately assessing tooth mobility, quantifying occlusal force performance, and effectively diagnosing pain during occlusion have long been critical technical challenges for dentists in clinical practice. While these assessments are essential for developing personalized treatment plans, preventing further tooth damage, and monitoring treatment effectiveness, the industry has long lacked a tool that combines efficiency, portability, and precision to systematically address these issues. Summary of the Invention

[0003] In view of this, the present invention creatively proposes a tooth loosening assessment pen (hereinafter referred to as "assessment pen"), aiming to fill this technological gap.

[0004] Specifically, this application relates to an assessment pen for the degree of tooth loosening, which consists of the following parts: a handle (1), a strain gauge (2), a sensor probe (3), a disposable sterile protective sleeve (4), a directional force transmission spring track (5), and a rigid conductive material (6); wherein the handle (1) is located at one end of the assessment pen as the main operating body, the handle (1) is connected to the directional force transmission spring track (5), the sensor probe (3) is placed on the upper part of the directional force transmission spring track (5), and the rigid conductive material (6) and the strain gauge (2) are respectively placed inside, wherein the rigid conductive material (6) is located between the sensor probe (3) and the strain gauge (2), and the directional force transmission spring track (5) and the sensor probe (3) on its upper part are wrapped by the disposable sterile protective sleeve (4).

[0005] This assessment pen integrates a precisely designed mechanical structure with advanced sensing technology to non-invasively and in real-time measure and record the displacement response of teeth under specific loads, thereby accurately quantifying the maximum compressive strength of teeth, i.e., their degree of looseness. This innovation not only greatly simplifies the assessment process and improves its convenience, but also provides dentists with objective and repeatable assessment data through its data-driven output, contributing to more precise and personalized dental treatment decisions.

[0009] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0010] This invention mainly involves a probe that contacts the tooth and uses an internal pressure sensor to measure the force. Doctors can then determine the pressure that the tooth can withstand based on the patient's feedback and the way the tooth is touched.

[0011] Specifically, it involves a pen for assessing the degree of tooth loosening, such as... Figure 1 As shown, it consists of the following parts: handle (1), strain gauge (2), sensing probe (3), disposable sterile protective sleeve (4), directional force transmission spring track (5) and rigid transmission material (6); wherein the handle (1) is located at one end of the evaluation pen as the main operating body, the handle (1) is connected to the directional force transmission spring track (5), the sensing probe (3) is placed on the upper part of the directional force transmission spring track (5), and the rigid transmission material (6) and strain gauge (2) are placed inside respectively, wherein the rigid transmission material (6) is located between the sensing probe (3) and the strain gauge (2), and the directional force transmission spring track (5) and the sensing probe (3) on its upper part are wrapped by the disposable sterile protective sleeve (4).

[0012] The following provides further explanation of the relevant components.

[0013] Handle (1): This component serves as the control center of the entire measurement system. It is ergonomically designed to provide medical personnel with a comfortable and stable grip experience, thereby facilitating precise operation and control. The handle design not only ensures ease of operation but also enhances the overall stability of the equipment through its robust structure.

[0014] Strain gauge (2): Located below the directional force transmission spring track (5), the strain gauge is the core sensor of the force measurement system. When the probe is subjected to an external force and the spring is compressed, this mechanical change is converted into a change in electrical signal on the strain gauge. The high precision characteristics of the strain gauge ensure the linearity and accuracy of the force value conversion, providing a reliable basis for subsequent data processing.

[0015] Induction Probe (3): This module is located at the front end of the system and is a key component that directly contacts the outside world and senses the force. The probe has a built-in high-sensitivity force sensing element, which can accurately capture the externally applied force and convert this force into the compression motion of the rear spring system through a carefully designed mechanical structure. In this process, the probe not only achieves effective force acquisition, but also ensures the accuracy of the measurement through its structural design.

[0016] Disposable sterile protective sleeve (4): In order to ensure hygiene and safety during the measurement process and avoid the risk of cross-infection, this system is specially equipped with a replaceable disposable sterile protective sleeve. The protective sleeve tightly wraps the probe part, which can effectively isolate pollutants in the external environment and prevent biological contamination that may occur during the measurement process, thereby ensuring the cleanliness and hygiene of the measurement system.

[0017] Oriented force transmission spring track (5): This system incorporates a spring track design to ensure that force transmission is strictly limited to the vertical direction. This design not only improves the accuracy of force measurement but also reduces force interference in non-target directions, making the measurement results more accurate and reliable. The optimized layout and material selection of the spring track further enhance the stability and durability of the system.

[0018] Rigid conductive material (6): used for the connection between the sensing probe (3) and the strain gauge (2) to transmit the biting force downward.

[0019] In some embodiments, the strain gauge (2) is internally connected to a force acquisition device, which includes a force acquisition circuit.

[0020] The resistance change of the strain gauge (2) becomes the core of this system's measurement, as shown in Figure 2, which illustrates the measurement circuit. The measurement circuit mainly consists of a strain gauge (acting as a variable resistor). R 1) A reference resistor with a fixed resistance value R 0 and a stable voltage source V The three components (0, 1, 2, 3) form a typical voltage divider circuit structure. In this circuit, the voltage across the strain gauge is obtained using a high-precision voltage measuring device. U 1. Then, using the basic formula (1) of the voltage divider circuit, the real-time resistance value of the strain gauge under the current stress state can be calculated. R 1.

[0021] Obtain the real-time resistance of the strain gauge R After step 1, the resistance value is further converted into the corresponding pressure value through mathematical calculation using the pre-calibrated resistance-pressure relationship formula (2). P This step is crucial for achieving accurate pressure measurement. Formula (2) is usually an empirical formula or mathematical model obtained by fitting experimental data, which can accurately reflect the mathematical relationship between resistance change and applied pressure.
