Abstract

The invention discloses a periodontal pocket depth measuring device which comprises a support, a connecting rod rotatably arranged on the support, a sleeve arranged at the first end of the support, a probe fixedly arranged at the first end of the connecting rod and capable of movably extending out of the sleeve, and a permanent magnet rotatably arranged in the second end of the support. The second end of the connecting rod is rotatably connected with the permanent magnet and can push the permanent magnet to rotate in the support, the middle of the connecting rod is rotatably connected with the support through a first rotating shaft, and a magnetic angle sensor is arranged at the position, located at the center of the side edge of the permanent magnet, in the second end of the support. A micro-control chip electrically connected with the magnetic angle sensor is further arranged in the second end of the support.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a periodontal pocket depth measuring device. Background technique [0002] Periodontal probing is an important method for clinical examination of periodontitis. Periodontal probes can be used to measure the depth and attachment level of periodontal pockets. The reliability of probing is very critical, especially the depth of periodontal pockets, which directly affects the doctor's diagnosis. [0003] Traditional measurement devices are mainly realized by photoelectric encoders and Hall elements. The photoelectric encoder has a complex structure and low precision, while the use of Hall elements has low sensitivity and high power consumption. In order to improve sensitivity and accuracy, additional components are required. Therefore, the volume and complexity of the device are increased, and the system reliability is also reduced. Contents of the invention [0004] Aiming at ...
