Description

Accurate accuse power periodontal probe

Technical Field

The invention relates to the technical field of periodontal probes, in particular to a precise force-control periodontal probe.

Background

Periodontal probes are the most common and important specialized periodontal examination instruments used primarily to measure the periodontal pocket depth. Periodontal probes are essential instruments in dental examinations and surgeries, and are the most important tools for diagnosing periodontal diseases and judging their severity.

However, physicians are often affected by various factors during the use of periodontal probes, wherein the probing pressure has a large influence on the accuracy of the measurement results. The probing force is usually controlled to be between 20 g and 25g, which is usually controlled by the hand feeling and experience of the doctor, thus causing human error. If the probing force is too great, the gingival junction may be punctured, and the periodontal failure condition is overestimated. If too little force is applied, the bottom of the pocket may not be detected and the destruction of the periodontal tissue may be underestimated. Whether the force is too large or too small, the real numerical value of the depth of the periodontal pocket can be influenced, so that the diagnosis and the treatment plan are influenced. A number of studies suggest that the amount of probing should be precisely controlled between 20-25 g.

In order to solve the technical problem that the pressure of a probe cannot be accurately detected when the depth of a periodontal pocket is detected in the prior art, and human errors exist, the application number is as follows: the patent of CN201310613516.9 discloses a periodontal probe capable of displaying probing pressure, which realizes the determination of probing pressure by connecting a pressure gauge between the probe and the support rod.

However, in the actual use of periodontal probes, the probe usually extends into the mouth, and the pressure gauge is disposed on the probe, which prevents the medical staff from viewing the value on the pressure gauge and is inconvenient to use.

Disclosure of Invention

The invention aims to provide a precise force-control periodontal probe, which can clearly judge probing pressure by medical staff in the process of using the periodontal probe.

The above object of the present invention is achieved by the following technical solutions:

the utility model provides a precision accuse power periodontal probe, includes end-to-end connection's test probe and handle, the handle is provided with and indicates the nip, indicate the peripheral parcel in nip to have the pressure sensor of film formula, the handle is close to the one end of test probe and is provided with the luminance pilot lamp of being connected with the pressure sensor electricity.

Through adopting above-mentioned technical scheme, using this periodontal probe in-process, medical staff can hold the handle of gripping, applys power in the finger pressure district through the finger, and the light that the luminance pilot lamp received according to the finger pressure district sends the light that represents different dynamics to make medical staff can the luminous situation of luminance pilot lamp judge the size of applying the dynamics.

As an improvement of the invention, one end of the holding handle, which is far away from the test probe, is provided with a display screen connected with the pressure sensor point.

As an improvement of the invention, one end of the holding handle close to the test probe is provided with an illuminating lamp.

Through adopting above-mentioned technical scheme, the setting of light can cooperate the camera, when test probe position light is dim, plays the effect of illumination for the image information that the camera acquireed is more clear, has also made things convenient for medical staff to look over the inside situation in oral cavity simultaneously.

As a improvement of the invention, the illuminating lamp is positioned on the side surface of the holding handle close to the probe tip of the test probe, and the position of the brightness indicator lamp and the position of the illuminating lamp are symmetrical relative to the axis center of the holding handle.

Through adopting above-mentioned technical scheme, because the light is located the side that the handle of gripping is close to test probe tip position for the light can illuminate the test probe and survey the position, and the light is symmetrical with the light, when the in-process that uses the probe, can make medical staff convenient see the light indicator.

As an improvement of the invention, the cross section of the finger pressing area is a convex polygon, and a pressure sensor is attached to each outer side face of the finger pressing area.

Through adopting above-mentioned technical scheme, finger pressure district cross section is protruding polygon, uses this periodontal probe in-process, and medical staff's finger can laminate in the lateral surface of finger pressure district to the convenient application of force to the periodontal probe, because each lateral surface of finger pressure district all posts pressure sensor, provides medical staff to the multiple handheld mode of periodontal probe.

In conclusion, the beneficial technical effects of the invention are as follows:

1. due to the arrangement of the camera, medical staff can see the condition of the lesion area more clearly and provide more intuitive reference;

2. the arrangement of the brightness indicating lamp provides judgment of the force applied by medical staff, and is simple and convenient;

3. the cross section of the finger pressure area is provided with the convex polygon, so that various holding modes of medical staff for the periodontal probe can be provided, and the comprehensive stress of each pressure sensor is also ensured.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the precision force control periodontal probe disclosed by the present invention comprises a test probe 1 and a grip handle 2 connected end to end, wherein a finger pressure area 211 is arranged on a portion of the grip handle 2 close to the test probe 1.

Wherein, the cross section of the finger-pressing area 211 is a convex polygon, preferably a convex hexagon, each outer side surface of the finger-pressing area 211 is attached with a pressure sensor 3, the pressure sensors 3 adopt resistance type film pressure sensors 3, the pressure sensors 3 are glued on the outer side surface of the finger-pressing area 211, and the adjacent pressure sensors 3 are mutually abutted.

The finger grip region 211 extends toward the end of the test probe 1 with a test column provided with a light indicator 5, a camera 6 and an illumination lamp 4. The illuminating lamp 4 is positioned on the side face of the holding handle 2 close to the tip part of the test probe 1, the position of the brightness indicating lamp 5 and the position of the illuminating lamp 4 are symmetrical relative to the axis center of the holding handle 2, and the camera 6 is arranged at the end part of the test column connected with the test probe 1. The end part of the holding handle 2 far away from the test probe 1 is provided with a display screen 7, and the display screen 7 is fixed at the end part of the holding handle 2 through a mounting shell 71 fixedly welded at the end part of the holding handle 2.
