Description

A periodontal probe with force control

Technical Field

The invention relates to the technical field of medical instruments, and in particular to a periodontal probe with force control.

Background Art

The periodontal probe is an essential instrument for periodontal examination. When in use, the periodontal probe is inserted into the periodontal pocket or gingival pocket to detect its depth and shape. It can also be used to detect the location of tartar. Probing is one of the important means of clinical periodontal examination.

At present, the common periodontal probes on the market are made of stainless steel and are divided into three parts: handle, neck and working end, all of which are single-ended. The working end is a tapering cylindrical or flat shape, bent at a certain angle, and is provided with millimeter grid lines or scale marks represented by different colors. However, the accuracy of probing depth measurement is closely related to the magnitude of the probing force, and the constancy of the probing force is one of the important factors affecting the accuracy of the probing depth. The probing force needs to be controlled between 20-25g. However, in the prior art, the periodontal probe needs to rely on the doctor's experience and feel to control the probing force, which not only affects the accuracy of the probing result, but also easily causes damage to the periodontal tissue due to excessive control force. For this reason, patents CN 103690261A (a periodontal probe capable of displaying probe pressure) and CN 110074888 A (a new type of precision force-controlled periodontal probe) use an electronic pressure sensor device to display the pressure during probing to assist the doctor in controlling the probing force. However, the electronic pressure sensor device has the problem of high manufacturing cost and damage to electronic components caused by high-temperature disinfection. The purpose of probing is to accurately measure the depth of periodontal pockets, but the electronic pressure sensors carried by existing invention patents cannot meet the exact needs of doctors and have limited clinical promotion value.

DETAILED DESCRIPTION

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

The purpose of the present invention is to provide a periodontal probe with force control to solve the technical problem that the probing force cannot be accurately controlled, which easily leads to damage to the periodontium and affects the accuracy of the probing result.

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in Figs. 1-4, the present invention provides a periodontal probe with force control, comprising a handle 1, a neck and a working part, wherein the handle 1, the neck and the working part are fixed together in sequence from head to tail, the handle 1 is used for holding by a dentist, the neck mainly plays a role of supporting and transmitting force, an extrusion section 23 is provided at one end of the neck close to the working part, an indicator ring 231 is fixedly provided in the middle of the extrusion section 23, the extrusion section 23 is used to connect the working part and transmit the probing force to the working part, the working part comprises a force control section 31 and a measuring section 32 fixedly connected from head to tail, the force control section 31 is used for the dentist to observe whether the probing force is reached, the measuring section 32 is used to extend into the patient's periodontal pocket or gingival pocket to measure its depth and shape, the force control section 31 is a shell 311 with an elastic element 313 inside, and the probing force is applied to the handle 1 The extrusion section 23 can extend into the shell 311 through one end of the shell 311, contact and squeeze the elastic element 313, and when the elastic element 313 is compressed to the point where the indicator ring 231 contacts the upper top surface of the shell 311, the probing force reaches the standard probing requirement, which is convenient for dentists to control the probing force and prevent periodontal damage due to excessive probing force. The measuring section 32 is provided at the other end of the shell 311 and extends from the lower bottom surface of the shell 311 in a direction away from the shell 311. A scale is provided on the measuring section 32 to facilitate dentists to read. The overall structure of the periodontal probe with force control is relatively simple, and it is possible to intuitively judge whether the force applied to the handle 1 reaches the standard probing force by observing whether the indicator ring 231 contacts the upper top surface of the shell 311, thereby ensuring measurement accuracy and effect.

Specifically, the diameter of the neck is smaller than the diameter of the handle 1, and the connection between the handle 1 and the neck has a smooth transition, which is convenient for dentists to hold and use.

The neck also includes a connecting section 21 and a supporting section 22. The connecting section 21, the supporting section 22 and the extruding section 23 are fixedly connected end to end in sequence, and the angle between the connecting section 21 and the supporting section 22 is an obtuse angle, and the angle between the supporting section 22 and the extruding section 23 is an obtuse angle. One end of the connecting section 21 is fixed to the neck as a whole. The neck is integrally formed and is not easily damaged. The connecting section 21 is used to connect the handle 1. The overall tortuous design of the neck enables the periodontal probe to be correctly placed on the root surface of different tooth positions. One end of the extruding section 23 contacts the elastic element 313 and can extrude the elastic element 313, thereby transmitting the probing force to the working part and facilitating the control of the probing force.

The working part includes a shell 311, a sliding element and an elastic element 313. An insertion hole is provided on the top surface of the shell 311, so that the extrusion section 23 can be inserted into the shell 311 through the insertion hole to apply force to the elastic element 313. A connecting hole is provided in the middle of the sliding element, and the inner wall of the connecting hole is provided with an internal thread. An external thread is provided on the outer wall of the extrusion section 23 that extends into the shell 311. The extrusion section 23 can be inserted into the connecting hole, and the internal thread is matched with the external thread. The extrusion section 23 is inserted into the shell 311 through the insertion hole and is threadedly connected with the sliding element to realize a detachable connection between the neck and the working part, which is convenient for later cleaning. One end of the elastic element 313 is fixedly connected to an end of the sliding element away from the neck, and the other end of the elastic element 313 is fixed to the inner bottom surface of the shell 311. The inner wall of the shell 311 is provided with a The slide rail extends from the bottom surface of the body 311, and the sliding element can slide along the slide rail. When the dentist applies a probing force through the handle 1, the extrusion section 23 drives the sliding element to slide in the slide rail toward the measuring section 32, the elastic element 313 is squeezed, and the measuring section 32 also moves toward the bottom of the periodontal pocket. When the bottom end of the measuring section 32 reaches the bottom of the periodontal pocket, the indicator ring 231 contacts the top surface of the shell 311. At this time, the standard probing force of 20 to 25 g is reached. This probing force is maintained, and the scale on the measuring section 32 is read. The force is transmitted through the elastic element 313 to achieve effective control of the probing force. As a better choice, the elastic element 313 is a spring, but the elastic element 313 in the periodontal probe with force control provided by the present invention is not limited to a spring, as long as it can be compressed in the shell 311 and the elastic coefficient is known.

The outer diameter of the indicator ring 231 is larger than the inner diameter of the insertion hole. When the probing force reaches the standard probing force, the indicator ring 231 can reach the upper surface of the shell 311 and be stuck by the upper surface, so that the dentist can more intuitively judge whether the standard probing force has been reached, and the indicator ring 231 will not enter the shell 311 through the insertion hole, affecting the judgment of the probing force.

The sliding element is an inner piston 312, and the outer wall of the inner piston 312 is circumferentially provided with an inner piston protrusion 314 extending outward. The inner piston protrusion 314 can be embedded in the slide rail and slide. However, the sliding element in the periodontal probe with force control provided by the present invention is not limited to the inner piston 312, as long as it can be detachably connected to the extrusion section 23 and slide back and forth in the shell 311.

There are two inner piston protrusions 314, and the two inner piston protrusions 314 are symmetrically arranged along the axis of the inner piston 312. There are two sliding rails, and the inner piston protrusion 314 can slide in the sliding rail along the direction consistent with the extension direction of the extrusion section 23. The sliding connection between the inner piston protrusion 314 and the rail can reduce friction and prevent the inner piston 312 from rotating in the shell 311 and affecting the measurement results. However, the number of inner piston protrusions 314 in the periodontal probe with force control provided by the present invention is not limited to two, as long as it can be set corresponding to the rail to assist the inner piston 312 to slide in the shell 311.

The shell 311 is a cylindrical shell 3, which is consistent with the shape of the outer wall of the inner piston 312, but the shape of the shell 311 in the periodontal probe with force control provided by the present invention is not limited to a cylindrical shell, as long as the sliding element and the elastic element 313 can be accommodated inside it and the sliding of the sliding element and the elastic element 313 is convenient.

The present specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
