[0002] The present application relates to the technical field of medical devices, more particularly to a thyroid separator for general surgery department. BACKGROUND

[0003] In thyroid surgery of general surgery department, the operator needs to finely dissect and separate thyroid tissue, blood vessels, nerves and surrounding fascia in a narrow neck space.

[0004] Based on the above, the present inventor found that the current clinical mainly relies on traditional metal separation forceps, mosquito forceps or electric hook and other instruments, which has the following defects: the front end of the instrument is a solid structure, which cannot directly observe the deep tissue level, especially when dealing with the back side or lower pole of the thyroid gland, it is easy to injure the recurrent laryngeal nerve or parathyroid gland, and the separation, traction and hemostasis need to frequently change the instruments, which prolongs the operation time, increases the risk of tissue exposure, and the light is seriously blocked in the deep part of the operation field, which affects the identification accuracy. Therefore, in view of the above, the existing structure is improved, and a thyroid separator for general surgery department is provided, so as to achieve the purpose of more practical value. SUMMARY

DETAILED DESCRIPTION

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Example: Please see Figures 1-4 A general surgical thyroid separator includes an end piece 1, a handle 2, and a hollow tubular rod 3. The handle 2 and the hollow tubular rod 3 are fixedly connected to the lower and right sides of the end piece 1, respectively. An installation sleeve 4 is fitted on the outer side of the hollow tubular rod 3, and an extension tube 5 is provided on one side of the hollow tubular rod 3. A flat nozzle 6 is installed on one side of the extension tube 5, and an installation sleeve 9 is fitted on the protrusion of the flat nozzle 6. A miniature camera 10 and an LED light 11 are respectively installed on the outer side of the installation sleeve 9, and an interface 1 and an interface 2 are respectively fixedly provided on the inner sidewall of the installation sleeve 9.

[0020] See Figure 1 and Figure 2 The control circuit board and battery compartment are located inside the end 1, and the switch 16 is installed on the outside of the mounting sleeve 4. The built-in rechargeable lithium battery powers the camera and LED.

[0021] See Figure 1 and Figure 3 The hollow tubular rod body 3 is equipped with flexible ribbon cable 12 and flexible ribbon cable 23 respectively. One side of flexible ribbon cable 12 and flexible ribbon cable 23 is electrically connected to the battery compartment, and the other side of flexible ribbon cable 12 and flexible ribbon cable 23 is connected to the miniature camera 10 and LED light 11 respectively. The flexible ribbon cable ensures that the signal is not interrupted when the angle of the flat nozzle 6 is repeatedly adjusted, thus ensuring the continuous stability of the image and lighting.

[0022] See Figure 3 and Figure 4 One end of the extension tube 5 is fixedly provided with a notch 8, and one side of the flat nozzle 6 is fixedly provided with a connecting bracket 15. The inner side of the notch 8 is hinged to the connecting bracket 15 through a movable shaft 14. This hinge structure allows the flat nozzle 6 to swing slightly within a range of ±15° to adapt to uneven tissue surfaces, achieve "flexible following" separation, and reduce mechanical stress concentration.

[0023] See Figure 3 and Figure 4 The flat mouth 6 is provided in two sets, and the surface of the flat mouth 6 is fixedly provided with corrugated sections 7. The corrugated sections 7 increase the surface friction, prevent tissue slippage, and at the same time disperse local pressure to avoid damaging the fragile glands.

[0024] See Figure 3 andFigure 4 Two sets of LED lights 11 are symmetrically arranged on both sides of the mounting sleeve 2 9, and the structure of each set of LED lights 11 is the same. The symmetrical lighting on both sides eliminates shadows and provides uniform, glare-free illumination with an illuminance of ≥5000 lux, which meets the requirement of clear visibility of deep surgical fields.

[0025] See Figure 3 and Figure 4 Figure 3 Figure 4 The miniature camera 10 is a CMOS sensor with a diameter of ≤1.5 mm and a resolution of 720P. Its ultra-small size ensures that it does not increase the volume of the instrument front end. The 720P resolution can clearly display nerve texture and vascular pulsation. The images are transmitted to the surgical monitor wirelessly or via wired means, supporting real-time navigation during the operation.

[0026] In use: The surgeon holds handle 2 and inserts the flat nozzle 6 through the neck incision into the thyroid surgical field. Pressing switch 16 on mounting sleeve 4 illuminates the LED light 11, and the miniature camera 10 begins acquiring images and transmitting them to the surgical display screen. The surgeon observes the tissue layers on the screen and gently pushes open the space between the true and false capsules of the thyroid gland using the corrugated sections 7 of the double flat nozzles 6. When encountering adhesions or dense fascia, the instrument can be slightly swung, utilizing the flexible hinge structure of the movable shaft 14 to perform blunt dissection following the tissue's direction. If it is necessary to pull tissue to expose deeper structures, one flat nozzle 6 can be used as a support point while the other is used for dissection, achieving multi-functional collaborative operation. The entire process requires no instrument changes, providing a clear field of vision, precise operation, and minimal tissue damage, significantly improving surgical safety and efficiency.
