Embodiment Construction

[0055] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] The purpose of the present invention is to provide a periodontal probe measurement system based on Hall elements, which can accurately measure the depth of the periodontal pocket, maintain a constant pressure during the probing process, automatically acquire and process the probing results,

[0057] in:

[0058] The periodontal pocket probe part includes a titanium alloy probe and a plastic sleeve for detecting the depth of the periodontal pocket;

[0059] The length of the probe is 20mm, and the tail end of the probe is a right angle with a smooth transition, which is connected to the front end of the lever; the working end of the probe is a spherical protrusion, which is used to extend into the bottom of the periodontal pocket;

[0060]The inner wall of the plastic sleeve is smooth, and the inner diameter is slightly larg...

Abstract

The present invention designs a periodontal pocket depth measurement device based on the Hall effect, which is mainly used for measuring the depth of the periodontal pocket, and specifically relates to the field of biomedical electronics technology, including: the first part, which is used to displace the periodontal probe It is converted into changes in magnetic field strength for digital measurement; the second part is used to keep the force constant under the condition of displacement changes; the present invention can realize the functions of high-precision and stable measurement of periodontal pocket depth and constant probing pressure, which solves the problem of existing The technology has problems such as low probe precision and unstable probing pressure, which can meet the needs of clinical probing.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a periodontal probe, in particular to a periodontal pocket depth measuring device based on the Hall effect. Background technique [0002] Periodontal probes are commonly used instruments for periodontal examinations, mainly used to measure the depth of periodontal pockets. The value and distribution of periodontal pocket depth are important indicators for the diagnosis of periodontal disease and the level of periodontal attachment. [0003] At present, the most commonly used periodontal probes in clinical practice are made of stainless steel, and the working end is provided with millimeter scale lines or scale marks expressed in different colors. The probing depth is recorded by another healthcare provider while the physician feels the resistance of the probe to the bottom of the periodontal pocket with his fingers. [0004] The accuracy of probing depth is closely relate...
