Problems solved by technology

[0008] At present, in order to preserve the vocal cord nerve during thyroid tumor surgery, a medical device that uses the conduction of the nerve to grasp the position of the nerve has been commercialized, but it is still under development. There are deficiencies in the device for grasping the position of the parathyroid glands

Abstract

The present invention relates to a parathyroid sensing system comprising: a modulator for generating a modulation signal having a predetermined frequency; a lock-in amplifier and a light source whichreceive information on the modulation signal; an excitation filter for transmitting, among light emitting from the light source, only excitation light that excites the parathyroid glands; a probe andan emission filter connected to the probe and selectively transmitting only autofluorescence emitting from the parathyroid glands; a near-infrared sensor for sensing the autofluorescence that has passed through the emission filter, and converting same into an electric signal; and a speaker for generating an alarm through the electric signal. By means of the present invention, the locations of theparathyroid glands may be precisely identified even when lights are turned on in an operating room, and convenience may be provided by alerting a surgeon by means of an alarm when the parathyroid glands are detected. In addition, the locations of the parathyroid glands may be precisely detected, even when the probe is not directly in contact with the parathyroid glands, by using the autofluorescence characteristics of the parathyroid glands.

Description

technical field [0001] The invention relates to a real-time detection device for parathyroid glands, more specifically, a detection system capable of grasping the position of the parathyroid glands by detecting the autofluorescence of the parathyroid glands. Background technique [0002] In thyroidectomy for removal of thyroid tumors, it is especially important to preserve the parathyroid glands, which maintain the body's calcium homeostasis. Parathyroid glands are very small and delicate organs with a weight of 35-45mg and a size of about 5x3x1cm. Therefore, it is difficult to distinguish parathyroid glands from surrounding tissues such as thyroid and lymph nodes with the naked eye. [0003] figure 1 (a) is a diagram showing the position of the parathyroid gland, figure 1 (b) is a diagram showing subgroups of lymph nodes. [0004] refer to figure 1 In (a), the parathyroid glands can be seen posterior to the thyroid in the anterior center of the neck. There are usually ...
