Embodiment Construction

[0030] like figure 1 The novel parathyroid gland detection device shown is composed of a probe 100 , a handle 200 , an external optical fiber cable 300 , a host 400 and a power adapter 500 .

[0031] The probe 100 has a probe lens 101 at the top, which can focus the emitted laser light on the tissue to be tested to increase the laser intensity, and can also focus and transmit weak fluorescent signals that are difficult to detect from the side to the optical fiber 8 .

[0032] The host 400 is composed of a cassette 401 , an internal optical fiber cable 402 , a laser emission unit 403 , a fluorescence detection unit 404 , a controller 405 , an HMI man-machine interface 406 , a wireless device 407 , a power supply system 408 and a battery 409 .

[0033] The HMI man-machine interface 405 can be displayed on a display screen, or can be displayed in the form of sound and light alarms, etc. There are various efficient identification and display methods, which are beneficial for clin...

Abstract

The invention discloses a novel parathyroid gland detection device which is composed of a probe, a handle, an external optical fiber cable and a host, a probe lens is arranged at the top end of the probe, the host comprises a cassette, an internal optical fiber cable, a laser emission unit, a fluorescence detection unit and a controller, and the external optical fiber cable and the internal optical fiber cable both adopt a single optical fiber design. The cassette comprises a laser light source, a photoelectric sensor, a first lens and a second lens, the laser light source is provided with a laser filtering cover, the surface of the photoelectric sensor is covered with a fluorescent filtering film, and the laser light source is placed on the photoelectric sensor. The parathyroid gland detection device is simple in structure, laser density can be improved, fluorescence signal intensity is enhanced, and accordingly parathyroid gland detection and recognition rate is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a novel parathyroid gland detection device. Background technique [0002] There are two pairs of parathyroid glands in the human body, which are brownish-yellow like soybeans, located in the middle and lower part of the back of the left and right thyroid lobes (or buried in them). calcium , Phosphorus metabolism. Hypoparathyroidism or complete removal (such as accidental removal during thyroid surgery), the secretion of PTH will be insufficient, resulting in a gradual decrease in blood calcium and a gradual increase in blood phosphorus, resulting in hypocalcemic convulsions and even death. Calcium salts can temporarily relieve symptoms. Since the parathyroid glands weigh 35-45mg and are around 2x3x4mm in size, the size is very small, and the location of the parathyroid glands is not static: the position of the upper parathyroid glands is relatively constant, about 77% are loc...
