Embodiment 1

[0073] Embodiment 1 A detection instrument for detecting parathyroid glands according to the present invention, comprising:

[0074] The AR glasses body 7 includes a spectacle frame 71 for wearing on the eyes and an enhanced display lens assembly 72 for enhancing the display of the position of the parathyroid gland. The spectacle frame is composed of a beam 711 and temples 712. A hollow cavity, and each of its lateral ends is fixedly connected to a mirror leg; a power supply, a near-infrared autofluorescence receiving device and a data signal processing component are arranged in the hollow cavity of the beam, and a near-infrared autologous Fluorescence excitation device 3 and near-infrared autofluorescence receiving device 5, the lateral ends of the front end of the beam are symmetrically equipped with a camera, and the two cameras form a visible light RGB binocular camera 15; the bottom of the beam along its Two pieces of enhanced display lens assemblies are fixed in the leng...

Embodiment 2

[0098] Embodiment 2 An application method of AR detection glasses for detecting the position of parathyroid glands, comprising the following steps:

[0099] S100: closing the first switch to supply power to the near-infrared autofluorescence excitation device; before receiving the laser conduction enabling signal from the data signal processing component, the laser diode of the near-infrared autofluorescence excitation device does not emit light;

[0100] S200: Close the second switch, supply power to the data signal processing component, the data signal processing component starts to work, and starts three subprocesses:

[0101] S300: Process 1, control the near-infrared autofluorescence excitation device to emit light and turn off; collect the image data from the near-infrared autofluorescence receiving device synchronized with the laser on and off operation; analyze the collected image data sequence to find the near-infrared autofluorescence The position of the thyroid glan...

Abstract

The invention provides AR detection glasses for detecting the position of a parathyroid gland. The AR detection glasses comprise a glasses frame, wherein the glasses frame comprises a cross beam and glasses legs, a hollow cavity is formed in the cross beam, and the two transverse ends of the cross beam are each fixedly connected with one glasses leg; a power supply, a near-infrared autofluorescence receiving device and a data signal processing assembly are arranged in the hollow cavity of the cross beam, and a near-infrared autofluorescence exciting device and a near-infrared light source illumination and autofluorescence receiving light path assembly are arranged in the middle of the front end face of the cross beam; the two transverse ends of the front end face of the cross beam are each symmetrically provided with a camera, and the two cameras form a visible light RGB binocular camera; and two enhanced display lens assemblies shielding the eyes of a user are fixedly installed at the bottom of the cross beam in the length direction of the cross beam, each enhanced display lens assembly comprises a lens and an AR displayer, the inner side edges, close to each other, of the two enhanced display lens assemblies are erected on the nose bridge, and the AR displayers are arranged in the lenses. The AR detection glasses have the advantages that the position of the parathyroid gland is rapidly detected and fused with an actual scene.

Description

technical field [0001] The invention relates to AR detection glasses for detecting the position of parathyroid glands, belonging to the field of medical operations. Background technique [0002] The parathyroid glands are small and changeable. In the visible light range, the parathyroid glands are similar to other tissues (such as fat) in color, and it is difficult to identify them during surgery. During thyroid surgery, the probability of parathyroid glands being injured or miscut is as high as 18-59% %. The protection of the parathyroid glands during the operation is extremely important to the recovery of the patient. Accidental injury can lead to hypoparathyroidism. The patient will suffer from numbness and convulsions due to calcium deficiency, which is extremely painful and requires calcium supplementation. The key to the protection of parathyroid glands is accurate identification. [0003] In addition, in some surgeries, the parathyroid glands need to be removed. Fo...
