As shown in fig. 4 and 5, the structure of the probe body 1 mainly includes: the device comprises a shell 11, a detection needle 12, a pull wire 13, a movable sleeve rod 14, a spring 15 and a displacement sensor. The shell 11 is a main structure of the probe body 1 and mainly plays a role of supporting other components, and the detection needle 12, the pull wire 13, the movable loop bar 14, the spring 15, the displacement sensor and other components are directly or indirectly arranged on the shell 11; in addition, the housing 11 also serves to facilitate handling by a doctor during operation.

The front end of the housing 11 is provided with a probe sleeve 111, and the probe 12 is movably sleeved in the probe sleeve 111. One end of the pull wire 13 is fixedly arranged on the probe 12, the other end of the pull wire 13 is fixedly arranged at the front end of the movable loop bar 14, and the pull wire 13 is in a tight state.

The rear end of the movable loop bar 14 is provided with a convex ring 141; the spring 15 is sleeved on the movable loop bar 14, one end of the spring 15 abuts against the inside of the shell 11, and the other end of the spring 15 abuts against a raised ring 141 at the rear end of the movable loop bar 14.

The probe body 1 realizes the function of measuring the depth of the periodontal pocket through the mutual matching of the probe 12, the pull wire 13, the movable sleeve rod 14 and the spring 15. When the probe needle 12 is continuously applied with a downward force after abutting against the bottom of the periodontal pocket, the probe needle 12 applies a traction force to the pull wire 13, the probe needle 12 moves upward along the probe sleeve 111, the pull wire 13 drives the movable loop bar 14 to compress the spring 15, and the movable loop bar 14 moves forward; when the probe needle 12 leaves the bottom of the periodontal pocket, the probe needle 12 stops applying traction force to the traction wire 13, the elastic force of the spring 15 drives the movable sleeve 14 to move backward, and the probe needle 12 moves downward along the probe sleeve 111. On the basis of the structure, the function of measuring the depth of the periodontal pocket can be realized by matching with a displacement sensor arranged on the movable sleeve rod 14, wherein the displacement sensor is used for measuring the depth of the periodontal pocket by measuring the displacement of the movable sleeve rod 14.

When the measurement is not started, the spring 15 provides an expansion force, so that the movable sleeve rod 14 has a tendency to move backwards, the movable sleeve rod 14 can pull the pull wire 13, so that the pull wire 13 is in a tight state, and the pull wire 13 drives the probe 12 and enables the probe 12 to be inserted downwards into the probe sleeve 111. To start the measurement, the doctor holds the housing 11 and extends the probe 12 into the periodontal pocket and then slowly advances it toward the bottom of the periodontal pocket. When the probe needle 12 abuts against the bottom of the periodontal pocket, the probe needle 12, the pull wire 13, the movable stem 14, the spring 15, and the like are in an initial state. At this time, the doctor applies downward pressure to the probe 12, and since the lower end of the probe 12 abuts against the bottom of the periodontal pocket, the probe 12 is stationary with respect to the oral cavity, but the probe sleeve 111 gradually descends, which corresponds to the probe 12 moving upward along the direction of the probe sleeve 111; at this time, the probe 12 drives the movable loop bar 14 to move against the elastic force of the spring 15 through the pulling rope, the spring 15 is further compressed, and the movable loop bar 14 moves forward. When the probe sleeve 111 descends to a certain degree, the probe sleeve will be abutted against the gum, and at this time, the length of the probe 12 exposed out of the lower end of the probe sleeve 111 is the depth of the periodontal pocket; correspondingly, the rising height of the probe 12 is the depth of the periodontal pocket; the probe 12 drives the pull wire 13 and the movable sleeve rod 14 to move in turn, the displacement of the movable sleeve rod 14 is the depth of the periodontal pocket, and the displacement of the movable sleeve rod 14 is measured by a displacement sensor, so that the depth of the periodontal pocket can be measured. After the measurement is finished, the doctor slowly takes out the probe needle 12 from the periodontal pocket, and because the abutting force between the bottom of the periodontal pocket and the probe needle 12 is no longer existed, at this time, the spring 15 which is further compressed before is restored to the initial state, so as to provide an expansion force to drive the movable sleeve rod 14 to move backwards; furthermore, the pull wire 13 drives the probe 12 to be inserted into the probe sleeve 111 again. In the present invention, for convenience of description and understanding, the body of the probe body 1 is defined by the direction of the probe 12 as the front side and the direction of the distal end of the housing 11 as the rear side.

In probe body 1, do not set up the scale that is used for the reading on probe 12, but through probe 12, pull wire 13, cooperation between components such as activity loop bar 14 and spring 15, convert the degree of depth of periodontal pocket into the displacement volume of activity loop bar 14, the measurement data of periodontal pocket depth can be acquireed to the displacement volume of measuring activity loop bar 14 through displacement sensor, not only can realize periodontal pocket depth measurement function, can also directly obtain the measurement data who acquires the digital, be convenient for follow-up direct application that carries on.

In order to adapt to the physiological structure of the oral cavity of the human body, in the present invention, the central axis of the housing 11 and the movement direction of the probe 12 are not on the same straight line, i.e. an included angle exists between the central axis of the movable loop bar 14 and the central axis of the probe sleeve 111, specifically, the included angle between the central axis of the movable loop bar 14 and the central axis of the probe sleeve 111 is 60-80 °. Because the one end of pull wire 13 is fixed to be set up on probe 12, the other end is fixed to be set up in the front end of activity loop bar 14, and the direction of motion of activity loop bar 14 and the axis coincidence of shell 11, consequently, at the measuring in-process, pull wire 13 is not along linear motion, but has certain transition angle of buckling, pull wire 13 has great frictional force in this transition angle department of buckling, it is not smooth and easy to lead to the motion of parts such as probe 12 and activity loop bar 14 not smooth, and then causes the influence to measurement accuracy.

As shown in fig. 6, in order to make the measurement more accurate, a direction-adjusting guide 112 is further provided at the front end of the housing 11, and the traction wire 13 is wound around the direction-adjusting guide 112. The direction adjusting guide wheel 112 is arranged at the front end of the shell 11, the traction wire 13 is wound on the direction adjusting guide wheel 112, and the friction force of the traction wire 13 at the bending transition angle can be reduced to the maximum extent through the direction adjusting guide wheel 112, so that the measurement accuracy is improved.

In order for the probe 12 to smoothly enter the periodontal pocket and reach the bottom thereof during the measurement of the periodontal pocket depth, the force applied to the probe 12 should be between 20-25 g. If the force applied to the probe pin 12 is too large, the probe pin 12 is directly inserted into the gum at the bottom of the periodontal pocket, causing damage; if the force applied to the probe 12 is too small, the probe 12 may not be fully inserted due to the obstruction of other tissues. Whether the force is too large or too small, this causes a problem that the measurement accuracy is lowered.

As shown in fig. 7 and 8, in order to further make the measurement more accurate, the utility model discloses an innovation point lies in: the probe 12 includes a needle portion 121 and a circular portion 122, the circular portion 122 is fixedly disposed at an upper end of the needle portion 121, and the needle portion 121 is movably sleeved in the probe sleeve 111. As shown in fig. 8, the traction wire 13 is divided into an outer wire body 131 and an inner wire body 132 by a contact portion with the direction-adjusting guide pulley 112.

The external wire body 131 and the external wire body 131 are connected end to form a traction wire 13; one end of the external wire 131 is fixedly disposed on the circular portion 122, and the external wire 131 is parallel to the probe 12. One end of the internal line 132 is fixedly disposed at the front end of the movable sleeve 14, and the internal line 132 and the central axis of the movable sleeve 14 are parallel to each other

The circular portion 122 is provided to enable the outer wire body 131 and the probe pin 12 to be parallel to each other. If the outer wire 131 and the probe needle 12 are not parallel to each other by providing the circular ring 122, it is conceivable that the angle between the outer wire 131 and the probe needle 12 is large at the beginning of measurement, but after the probe needle 12 abuts against the bottom of the periodontal pocket, the probe needle 12 gradually moves upward along the probe sleeve 111 as the doctor continues to apply pressure, and the angle between the outer wire 131 and the probe needle 12 gradually decreases. As the measurement is carried out, even if the force applied to the shell by the doctor is constant, the force applied to the pull wire 13 by the probe needle 12 changes nonlinearly due to the decomposition of the force in different directions, the force applied to the probe needle 12 becomes larger, and the force applied to the probe needle 12 is difficult to be kept within the range of 20-25g, thereby affecting the measurement accuracy.

In the above preferred embodiment, the circular ring portion 122 is provided to keep the included angle between the outer wire 131 and the inner wire 132 constant, and during the measurement, the outer wire 131 and the probe 12 are parallel to each other, so as to ensure the force applied to the probe 12 to be between 20 and 25g as much as possible, thereby improving the measurement accuracy.

In the prior art, whether the probe 12 is in place is generally determined by the subjective experience of a physician. The doctor applies downward force to the probe needle 12 through the shell 11, and when the reaction force applied to the probe needle 12 is not large, the doctor judges that the probe needle 12 is not in place; when the reaction force to which the probe needle 12 is subjected is large, the doctor judges that the probe needle 12 is already in position.
