Problems solved by technology

[0006] Aiming at the existing products on the market at present, the intensity of received light is low, the ratio of noise to noise is poor, the divergence angle of emitted light is large, the system is complicated, and it is impossible to realize one-time aseptic use, etc., and proposes an L-shaped optical path The parathyroid gland detection device not only increases the laser density and enhances the fluorescence signal intensity, but also greatly improves the detection and recognition rate of parathyroid glands. It can clearly distinguish parathyroid glands from surrounding tissues such as thyroid and fat, and can achieve aseptic operation, which has great clinical significance.

Embodiment Construction

[0031] like figure 1 The illustrated parathyroid gland detection device based on an L-shaped optical path is composed of a probe 100 , a handle 200 , an optical fiber cable 300 , a portable host 400 and a power adapter 500 .

[0032] 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 302 .

[0033] The portable host 400 is composed of an L-shaped optical path 401 , a laser emission unit 402 , a fluorescence detection unit 403 , a controller 404 , an HMI man-machine interface 405 , a wireless device 406 , a power supply system 407 and a battery 408 .

[0034] The HMI man-machine interface 405 can be displayed on a display screen, and can also be displayed in the form of sound and light alarms. Various efficient identification and display methods are useful for cli...

Abstract

The invention discloses a parathyroid gland detection device based on an L-shaped light path, the parathyroid gland detection device is composed of a probe, a handle, an optical fiber cable and a portable host, the L-shaped light path is arranged in the portable host so that emitted laser signals and received fluorescence signals are transmitted through the same optical fiber, a probe lens is arranged at the top end of the probe, and the probe adopts a replaceable design. According to the invention, the effective utilization rate of exciting light can be improved, the laser density can be improved, and the fluorescence signal intensity can be enhanced, so that the parathyroid gland detection and recognition rate can be improved, and one-time sterile operation can be realized, which has great clinical significance.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a parathyroid gland detection device based on an L-shaped optical path. 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...
