Description

Technical Field

[0001] The utility model relates to the field of medical probing auxiliary equipment, in particular to a novel periodontal probing dynamometer. Background Art

[0002] Periodontal probing is one of the common oral examination items. During periodontal probing, the tip of the probe is used to explore the gingival sulcus or periodontal pocket of each tooth surface. The force should be light, about 20-25g. This force is usually determined by the experience or personal cognition of medical staff. For those who lack experience, it is difficult to control the force more accurately, which affects the accuracy of the periodontal probing results.

[0003] The utility model patent with announcement number CN209992092U proposes a periodontal probing dynamometer, which can be used by medical staff for touch and pressure training to achieve force perception and control. However, the probing port of the dynamometer faces upward, and the direction of the probe body tends to be horizontal when the probe is held. Therefore, the probing port will affect the downward pressure depth of the probe body and the probe tip, thereby affecting the training. At the same time, the dynamometer can only train the downward touch and pressure force, and cannot simulate the upward touch and pressure force for the upper teeth to train, so the training is incomplete.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: See Figure 1 and Figure 2As shown, the utility model provides a new type of periodontal probing force measuring device, including a detection tube 1 with both upper and lower ends blocked, the detection tube 1 is a cylindrical structure, a receiving cavity is provided in the detection tube 1, a detection port 101 is provided in the middle section of the side circumference of the detection tube 1, the detection port 101 is connected to the receiving cavity, and the upper and lower edges of the detection port 101 extend to the upper and lower parts of the detection tube 1 respectively, and a detection seat 4 that slides up and down is provided at the detection port 101 in the receiving cavity, and the arc of the detection port 101 corresponds to a central angle of 120°, which can not only ensure the width of the detection port 101 but also ensure the stable sliding of the detection seat 4 in the detection tube 1. A first spring 2 is connected between the upper end surface of the detection seat 4 and the inner top surface of the detection tube 1, or a second spring 3 is connected between the lower end surface of the detection seat 4 and the inner bottom surface of the detection tube 1. Either the first spring 2 or the second spring 3 can be selected, or the two can be combined and used together.

[0020] On the basis of the above embodiment, the detection base 4 includes an upper base 401 and a lower base 403 which are spaced apart from each other, the space being not less than 2 cm, and a first spring 2 is connected between the upper end surface of the upper base 401 and the inner top surface of the detection tube 1, and a second spring 3 is connected between the lower end surface of the lower base 403 and the inner bottom surface of the detection tube 1. In this embodiment, the upper base 401 and the lower base 403 are separated and independent from each other, so in this embodiment, the first spring 2 is used to measure the force from the upper base 401, and the second spring 3 is used to measure the force from the lower base 403.

[0021] On the basis of the above embodiment, the upper base 401 and the lower base 403 can be connected into an integrated structure, such as a connecting wall 402 is connected between the upper base 401 and the lower base 403, and an operating port 4021 is provided on the side of the connecting wall 402 facing the detection port 101. The arc of the operating port 4021 corresponds to the center of the circle and refers to the detection port 101. At this time, the first spring 2 and the second spring 3 work together to measure the force from the detection seat 4. It should be noted that the mass of the detection seat 4 is preferably controlled below 10g, because during upward touch and pressure training, it is necessary to first overcome the weight of the detection seat 4 and then press to deform the first spring 2 and the second spring 3, so as to achieve the purpose of measurement through spring deformation.

[0022] On the basis of the above embodiment, the outer circumferential surface of the connecting wall 402 is formed with a limiting ridge 404 distributed along the axial direction, and the inner circumferential surface of the detection tube 1 is provided with a limiting groove 102 adapted to the limiting ridge 404. By setting the limiting ridge 404 and the limiting groove 102, deflection or displacement of the detection tube 1 when sliding up and down can be avoided.

[0023] On the basis of the above embodiment, the height of the detection port 101 is three times the height of the detection seat 4, and the outer circumferential surface of the detection tube 1 is provided with scale lines 103. The inner top surface and the inner bottom surface of the detection tube 1 are both connected with a counterweight seat 104, and the counterweight seat 104 is arranged in the first spring 2 / second spring 3. The stability of the force measuring device when placed is improved by adding the counterweight seat 104, and the counterweight seat 104 can limit the position of the spring and prevent the spring from unstable deflection.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
