Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a spinal surgical curette device with integrated cold light source. Background Technology

[0002] In spinal surgery, the surgical area is deep and the space is narrow. Traditional curettes lack lighting functions and rely on external light sources. However, traditional curettes rely on external cold light surgical lamps or indirect lighting from endoscopes. The instrument itself has no light source, which results in the curette body blocking the light and creating shadows. It is difficult to clearly identify key areas and increases the risk of surgical operation. Existing cold light source technology is mostly used in endoscopes or independent lighting devices, but it is not directly integrated with curettes, resulting in single instrument function and cumbersome operation.

[0003] Therefore, there is an urgent need for a curette that integrates a cold light source to achieve precise local illumination, reduce interference from external light sources, and improve the accuracy and safety of surgical procedures. Utility Model Content

The USB charging interface 15 is embedded in the side wall of the proximal end of the handle body 11. The USB charging interface 15 is electrically connected to the power supply 13, and the power supply 13 is charged through the USB charging interface 15.

[0037] Among them, the cold light source 14 adopts a high color rendering LED cold light source (color temperature 5500K±500K, color rendering index ≥90%).

[0038] The output end of the cold light source 14 is connected to the optical fiber bundle 16 and is fixed to the inner wall of the handle body 11 by a heat dissipation silicone sheet to ensure efficient heat dissipation. The outer layer of the optical fiber bundle 16 is provided with a metal braided mesh, which can protect the internal fibers and extend the service life of the device.

[0039] The connecting rod 2 is a hollow tubular structure, and a through hole 22 is provided along the axial direction of the connecting rod 2. The through hole 22 communicates with the receiving cavity.

[0040] The diffuser 21 is fixed to the far end of the connecting rod 2 with optical adhesive;

[0041] The scraper 3 includes: a first scraper bar 31 threadedly connected to the distal end of the connecting rod 2, a second scraper bar 32 fixedly connected to the distal end of the first scraper bar 31, and a scraper head 33 fixedly disposed at the distal end of the second scraper 32. The second scraper bar 32 and the scraper head 33 have an included angle, and the included angle between the second scraper bar 32 and the scraper head 33 is 90°.

[0042] A scattering sheet 21 is fixedly provided at the distal end of the first scraper bar 31, and the distal end of the optical fiber bundle 16 is fixedly connected to the scattering sheet 21 through the through hole 22;

[0043] The second scraper bar 32 is fixedly provided with an electromagnetic attraction device 321 at its distal end, and a hexagonal metal connector 331 is fixedly provided with a proximal end of the scraper head 33. The electromagnetic attraction device 321 has a hexagonal groove 322, and the hexagonal metal connector 331 matches the hexagonal groove 322. The hexagonal metal connector 331 is magnetically connected to the electromagnetic attraction device 321, and the electromagnetic attraction device 321 is electrically connected to the control main board 12.

[0044] The power supply 13 and the cold light source 14 are both electrically connected to the control motherboard 12. The control motherboard 12 integrates a microprocessor and control circuit to control the cold light source 14.

[0045] The first scraper bar 31 and the second scraper bar 32 are both made of metal.

[0046] The first scraper bar 31 is shaped like a frustum, and the second scraper bar 32 is shaped like a semi-cylindrical frustum. The diameter of the bottom surface at the far end of the first scraper bar 31 is the same as the diameter of the bottom surface at the near end of the second scraper bar 32.

[0047] Among them, the scraper head 33 is "spoon" shaped, which is concave in the middle to form a spoon-like recessed space that can temporarily hold scraped tissue debris.

Then, the cold light source 14 is activated via the control motherboard 12. The doctor holds the handle body 11 and aligns the scraper 3 with the surgical site. The light emitted by the cold light source 14 is transmitted to the diffuser 21 via the optical fiber bundle 16, evenly illuminating the surgical field. When it is necessary to adjust the angle of the scraper head 33, the electromagnetic suction device 321 is de-energized and demagnetized via the control motherboard 12 on the handle. At this time, the scraper head 33 can be removed, and the angle of the scraper head 33 can be rotated to adjust to the required angle. Then, the hexagonal metal connector 331 is aligned and placed into the hexagonal groove 322. The electromagnetic suction device 321 is energized again, and the scraper head 33 is fixed by magnetic attraction. With the angle design between the second scraper rod 32 and the scraper head 33, it can flexibly scrape away diseased tissue around the spine and adapt to narrow surgical spaces.
