A positioning mechanism of an infrared thermal imager for examining human parathyroid glands

Abstract

The invention provides a positioning mechanism of an infrared thermal imager for inspecting human parathyroid glands, and relates to the field of medical infrared thermal imagers. The positioning mechanism of the infrared thermal imager for inspecting human parathyroid glands includes a gravity base, and the bottom of the gravity base is fixedly connected with universal wheels for rolling. The positioning mechanism of the infrared thermal imager used to examine the parathyroid glands of the human body, through the electric telescopic rod installed inside the cylindrical shell, the expansion and contraction of the electric telescopic rod can push the circular block to move, and the circular block can drive the stable contact tube The snapping bump 1 and the snapping bump 2 on the second move and engage with the snapping groove 1 and the snapping groove 2, which can effectively connect the snapping bump 1 and the snapping groove 2 after the drive linear motor stops working. The meshing between the two connecting bumps reduces the problem of shaking of the thermal imager caused by the meshing gap between the transmission gear and the inner ring teeth, and greatly improves the imaging stability of the thermal imager.

Description

technical field [0001] The invention relates to the field of medical infrared thermal imagers, in particular to a positioning mechanism of an infrared thermal imager for examining human parathyroid glands. Background technique [0002] The thermal imager uses the infrared detector and the optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector to obtain an infrared thermal image, which is consistent with the thermal distribution on the surface of the object. corresponding to the field. In layman's terms, a thermal imager converts the invisible infrared energy emitted by an object into a visible thermal image. Different colors on the top of the thermal image represent different temperatures of the measured object. [0003] The infrared thermal imager is heavy, and the measurement process requires stability. Therefore, the infrared thermal imager...

AI Technical Summary

Problems solved by technology

However, since the operating table shakes during work, this directly affects the detection of the parathyroid glands of the human body by the thermal imager, and the shaking of the infrared thermal imager directly affects the deviation of the imaging, which is likely to cause detection errors, and During the activity of the infrared thermal imager, there will be meshing gaps between the gears. During the process of starting the motor, there will be gaps in the meshing parts of the gear transmission, which will easily cause the infrared thermal imager to shake.

Secondly, thermal imaging cameras are highly sophisticated instruments that cannot be sterilized

The operating table is a sterile environment, and each fixation process is very cumbersome, and there is a possibility of bacterial contamination, which poses a threat to the safety of patients
