[0051] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0052] Please refer to Figures 1-10 The present invention discloses a parathyroid gland detection device, which consists of six parts, as follows: Figures 1-3 The device includes a limiting component 1, a mounting housing 2, a beam guide 3, a signal conversion component 4, a light transmission component 5, a connecting lens 6, and an endoscope light source interface 9. A detachable beam guide 3 is installed on the upper end of the mounting housing 2, and the beam guide 3 introduces a laser beam. The limiting component 1 is installed at the rear end of the mounting housing 2, and a signal transmission cable is installed in the limiting component 1. The connecting lens 6 is installed at the front end of the mounting housing 2, and the light transmission component 5 is installed inside the mounting housing 2. One end of the light transmission component 5 faces the connecting lens 6, and the other end of the light transmission component 5 is connected to the signal conversion component 4. In the first use state, the connecting lens 6 is connected to the endoscope, and the beam guide 3 is connected to the endoscope light source interface 9. In the second use state, the beam guide 3 is inserted into the upper end of the mounting housing 2.

[0053] In use, this invention determines whether to perform open or closed thyroid surgery based on the patient's physical examination and wishes. If open surgery is performed, due to the larger opening area, the mounting housing 2 can be placed into the surgical site. Before placement, one end of the beam guide 3 is connected to the connector 25, and the other end of the beam guide 3 is connected to the laser source. During detector assembly, the signal transmission cable is electrically connected to the signal conversion component 4. The detector with the beam guide 3 is then inserted into the surgical opening, and the laser source is activated. The laser source emits a 700-nanometer laser beam, which is transmitted through the beam guide 3. A light-transmitting lens is provided on the connector 25, through which the laser beam passes. The light beam diverges through a lens, while a 700-nanometer laser beam excites a fluorescence signal pre-set on the parathyroid gland. The fluorescence signal is excited by dye molecules absorbing two or more photons in a short time, reaching an excited state, then undergoing an internal conversion back to the ground state, releasing energy as fluorescence emission. This fluorescence is received by the connecting lens 6 and transmitted through the light transmission component 5. Finally, the fluorescence signal is absorbed by the CMOS sensor 41. When light reaches the surface of the CMOS sensor 41, the photodiode in each pixel receives the photons and converts them into electrons. The charge generated by the photodiode is stored in each pixel, and the amount of charge reflects the intensity of the light received by the pixel. Strong light generates more charge, while weak light generates less charge. These charges are then converted into analog voltage signals and processed by the integrated circuit of CMOS sensor 41. The processed voltage signal is sent to the imaging device via a signal transmission cable, enabling real-time monitoring of the parathyroid gland location to prevent accidental cutting. Simultaneously, a laser illuminates the cavity, while another CMOS sensor receives visible light signals. The visible light illuminates the tissue, and then the lens 6 feeds the image of the illuminated area back to the CMOS sensor. The CMOS sensor processes the image signal into an electrical signal, which is transmitted via a signal transmission cable. Finally, on the imaging device, the tissue pattern and the fluorescence signal of the parathyroid gland location are displayed. During open surgery... During the procedure, the endoscope is connected to the connecting lens 6, and the endoscope light source interface 9 is connected to the beam guide 3. After the endoscope is aligned with the surgical position, the light emitted by the laser light source is transmitted to the front end of the endoscope through the beam guide (optical fiber) to illuminate the inside of the human body being observed. The same 700-nanometer laser beam can also excite the fluorescence signal. Finally, the visible light illumination forms the image information and fluorescence signal, which are transmitted through the endoscope. The light signal passes through the endoscope and is transmitted to the connecting lens 6. The light signal is finally transmitted to the signal conversion component 4, which converts the light signal into an electrical signal. The electrical signal is then used by the imaging device to present the image of the surgical position.

[0054] In a specific embodiment, such as Figure 4The connecting lens 6 includes a connecting block 61, a circular groove 62, an internal thread structure 63, and a protrusion 64. The connecting block 61 has a circular groove 62 inside, and one end of the connecting block 61 is connected to the front end of the mounting housing 2. The protrusion 64 is connected to the front end of the connecting block 61, and the protrusion 64 has an internal thread structure 63 inside. Several threaded grooves are formed on the connecting block 61. By fastening bolts passing through the threaded grooves, the connecting block 61 is connected to the plane 24. The circular groove 62 is used for the installation of the lens group 8. The internal thread structure 63 is designed to cooperate with the external thread structure 72 to connect the connecting lens 6 to the buckle 7.

[0055] In a specific embodiment, such as Figure 3 and Figure 5 A buckle 7 is connected to the protrusion 64. The buckle 7 includes a limiting ring 71, an external thread structure 72, and a column 73. The external thread structure 72 is provided on the outer surface of the rear end of the column 73. The limiting ring 71 is sleeved on the outside of the column 73 and is located at the front end of the external thread structure 72. The front end of the column 73 is connected to the endoscope. The design of the limiting ring 71 can limit the depth of the rear end of the endoscope inserted into the column 73, preventing damage caused by collision between the endoscope and the lens group 8. Through the threaded connection between the column 73 and the endoscope, and the threaded connection between the column 73 and the connecting lens 6, installation is satisfied while achieving quick connection. After the endoscope light source interface 9 is connected to the beam guide 3, the laser beam of the laser source irradiates the thyroid surgery site. The image signal is reflected through the endoscope for light signal transmission. The transmitted light signal passes through the buckle 7 and enters the connecting lens 6. The imaging method is the same as the imaging method during the use of the detector.

[0056] In a specific embodiment, such as Figure 6The light transmission assembly 5 includes a mounting block 51, an optical adapter 52, a cylinder 53, a clamping spring 54, and a receiving lens 55.

One end of the clamping spring 54 abuts against the cylinder 53, and the other end of the clamping spring 54 abuts against the end of the receiving lens 55. The optical adapter 52 is used to connect the prism frame 44 and the mounting block 51. The through slot in the mounting block 51 and the cylinder 53 is for light to pass through. Regarding the design of the clamping spring 54, when the light transmission assembly 5 is installed, when the mounting block 51 is fixed inside the mounting housing 2 by bolts, the receiving lens 55 will press against the lens group 8. At this time, the clamping spring 54 is in a compressed state, so that the receiving lens 55 continues to press against the lens group 8. This design can reduce the dispersion of light during transmission, resulting in better imaging effect. The receiving lens 55 is used to transmit light signals, the small hole is used for light to pass through, and the threaded hole is used to fix the mounting block 51.

[0057] In a specific embodiment, such as Figure 7 The signal conversion component 4 includes a CMOS sensor 41, a receiving component 42, a threaded interface 43, and a prism frame 44. One end of the prism frame 44 has a threaded interface 43, which is screwed onto one end of the optical adapter 52. The receiving component 42 is installed within the prism frame 44. Two CMOS sensors 41 are provided; one CMOS sensor 41 is connected to a fluorescence imaging device via a signal transmission cable, and the other CMOS sensor 41 is connected to a visible light imaging device via a signal transmission cable. The receiving component 42 receives light signals, and an image is displayed on it. This image is transmitted to the CMOS sensor 41, activating the diodes on the CMOS sensor 41 and converting them into electrical signals. Thus, the image signal is transmitted to the imaging device in electrical form for imaging. The threaded interface 43 is used to connect to the optical adapter 52.

[0058] In a specific embodiment, such as Figure 8The mounting housing 2 includes a signal transmission cable clamp 21, a connecting hole 22, a connecting cylinder 23, a flat surface 24, a connector 25, and a housing 26.

A flat surface 24 is provided at the front end of the housing 26, on which a connecting lens 6 is mounted. The bottom end of the connector 25 is inserted into the slot, and the upper end of the connector 25 is connected to a beam guide 3. The signal transmission cable clamp 21 is used to restrict the signal transmission cable and prevent signal transmission termination due to cable displacement. The connecting cylinder 23 can be used with bolts to connect the two housings 26 together. The flat surface 24 is used to mate with the connecting lens 6. The connector 25 is the link between the housing 26 and the beam guide 3, and a lens is installed on the connector 25 to disperse part of the laser.
