Description

Technical Field

[0001] The utility model relates to the technical field of surgical equipment, in particular to a photoelectric integrated patient interface box and a surgical device. Background Art

[0002] During thyroid surgery, identifying and protecting the recurrent laryngeal nerve and parathyroid glands are two of the most pressing issues. Damage to the recurrent laryngeal nerve, which controls vocal cord movement, can lead to hoarseness and difficulty breathing. The recurrent laryngeal nerve connects to the vagus nerve, and damage anywhere along the nerve pathway can prevent the vocal cords from opening and closing properly. Inadvertent removal or damage of the parathyroid glands can lead to hypocalcemia, requiring lifelong medication and severely impacting quality of life.

[0003] Therefore, intraoperative detection of the recurrent laryngeal nerve and parathyroid glands has become extremely important. By detecting and monitoring the recurrent laryngeal nerve during surgery, surgeons can avoid nerve damage and promptly remedy any damage. Regarding the parathyroid glands, surgeons can use detection equipment to promptly locate and protect them during surgery. [The following appears to be unrelated and likely a separate topic:] Technical problems exist in existing technologies.

[0004] For laryngeal recurrent nerve monitoring, there are commercially available products that utilize electrical nerve stimulation combined with electromyographic signal acquisition. Meanwhile, for the parathyroid glands, a current technology utilizes their autofluorescence under near-infrared light to identify them. Terminal applications include cameras and probes.

During operation of the parathyroid gland detection circuit, the light source module 101 outputs light, the excitation optical path module 102 adjusts the light source to excitation light and directs the excitation light into the subject along the probe 200, the receiving optical path module 104 receives the fluorescence generated by the subject in response to the excitation light through the probe 200, and transmits the fluorescence to the spectrometer 105.
