Description

Technical Field

[0001] The present invention belongs to the technical field of thoracic cavity illumination, and particularly relates to an endothoracic thoracoscope illumination device. Background Art

[0002] Thoracoscope illumination is a key link in thoracoscopic surgery. It refers to using specialized illumination equipment to provide sufficient light for the operation of the thoracoscope in the thoracic cavity, enabling the surgeon to clearly observe the tissue structure and lesions in the thoracic cavity. Mainly, strong light is emitted by a light source, and the light is conducted through an optical fiber or directly enters the thoracoscope through an optical system, and then illuminates inside the thoracic cavity. The light source is usually a high-brightness cold light source to reduce thermal damage to the tissues in the thoracic cavity. The thoracic cavity contains important organs such as the heart, lungs, large blood vessels, esophagus, etc., as well as fine structures such as nerves and lymphatic vessels. Good illumination can clearly show the contours, surface features, and lesion conditions of these structures, helping the doctor accurately diagnose the condition and perform surgical operations. Traditional thoracoscopic surgeries usually require multiple incisions on the patient's body surface to insert the thoracoscope and other surgical instruments. Existing thoracoscope illumination devices are mostly fixed outside the patient through complex external support structures or in combination with other instruments. This not only occupies a large amount of surgical operation space, but also increases the complexity of the surgery, easily causes additional trauma to the patient, and also affects the efficiency and safety of the surgery to a certain extent. For this reason, we have proposed an endothoracic thoracoscope illumination device. Summary of the Invention

[0034] Please refer to Figure 1-8As shown in the figure, the present invention is an endothoracic thoracoscope lighting device, which includes a housing 1, a drive motor 15 and a telescopic rod 6. The housing 1 has a square hollow structure, and an opening is provided on the surface of the housing 1. A rotating cover 2 is installed outside the opening of the housing 1, and a universal ball 7 is installed at the center position of the housing 1. The universal ball 7 has a spherical structure, and two groups of rotating shafts 8 are installed at the center position on the side of the universal ball 7. The two groups of rotating shafts 8 are at right angles to each other. A transverse frame 9 and a longitudinal frame 10 are respectively sleeved outside the two groups of rotating shafts 8. The transverse frame 9 and the longitudinal frame 10 have a right-angled bending structure. One end of the transverse frame 9 and the longitudinal frame 10 are respectively rotatably connected to the rotating shaft 8, and the other ends of the transverse frame 9 and the longitudinal frame 10 are respectively installed with two groups of rotating sleeves 12. The two groups of rotating sleeves 12 have a cylindrical hollow structure. One end of the rotating sleeve 12 is fixedly connected to the transverse frame 9 and the longitudinal frame 10, and the other end of the rotating sleeve 12 is rotatably connected to the inner wall of the housing 1.

The threaded rod 14 meshes with the tooth block 13. One end of the threaded rod 14 is rotatably connected to the inner wall of the housing 1, and the other end of the threaded rod 14 is installed with a drive motor 15. The housing of the drive motor 15 is fixedly connected to the inner wall of the housing 1, and the output end of the drive motor 15 is fixedly connected to the threaded rod 14.

One end of the rotating frame 17 is sleeved outside the threaded rod 14, and the other end of the rotating frame 17 is fixedly connected to the inner wall of the housing 1 on the side away from the rotating cover 2. By driving the threaded rod 14 to rotate with the drive motor 15, since the threaded rod 14 meshes with the tooth block 13 on the rotating sleeve 12, the drive motor 15 drives the rotating sleeve 12 to rotate. The transverse frame 9 and the longitudinal frame 10 are respectively installed on the two groups of rotating sleeves 12. The rotation of the transverse frame 9 drives the universal ball 7 to rotate horizontally, and the rotation of the longitudinal frame 10 drives the universal ball 7 to rotate vertically.

By using the power of the telescopic rod 6 itself, the distance between the lighting module 5 and the lesion position is adjusted. An LED light source with high brightness and low heat generation is adopted, which can provide sufficient endoscope illumination brightness to meet the clear observation requirements of the surgical field in the chest cavity. The outer shape design of the lighting module 5 conforms to the space structure in the chest cavity, reduces the volume, and avoids interfering with the organs in the chest cavity and surgical operations.

A through hole 25 is formed on the magnetic attraction block 23. The position of the through hole 25 corresponds to that of the threaded hole 21, and a bolt 22 is inserted into the through hole 25. The four bolts 22 pass through the through hole 25 and are threadedly connected in the threaded hole 21.

[0037] Wherein, a power supply unit 18 is installed on the inner wall of one side of the outer shell 1 away from the rotating cover 2. The output end of the power supply unit 18 is electrically connected to the driving motor 15, the lighting module 5, and the telescopic rod 6.

The camera assembly is docked with the transmission line 20 to transmit information to the external display device.

[0038] The working principle of the present invention is as follows:

[0039] Please refer to Figure 1-8 As shown, the present invention is an endoscope lighting device for internal thoracic cavity. Before the operation, the lighting module 5 is fixed at a suitable position on the inner side of the patient's chest wall according to the operation requirements by magnetic attraction or using a sticky material with good biocompatibility. If the built-in battery is used for power supply, ensure that the battery has sufficient power. If the external power supply is used, connect the signal transmission line 20 and ensure the stable power supply. During the operation, the lighting device is turned on to provide clear endoscopic lighting in the thoracic cavity. The doctor can perform surgical operations through other surgical instruments such as an endoscope. The driving motor 15 drives the threaded rod 14 to rotate. Since the threaded rod 14 meshes with the tooth block 13 on the rotating sleeve 12, the driving motor 15 drives the rotating sleeve 12 to rotate. A transverse frame 9 and a longitudinal frame 10 are respectively installed on the two rotating sleeves 12. The rotation of the transverse frame 9 drives the universal ball 7 to rotate horizontally, and the rotation of the longitudinal frame 10 drives the universal ball 7 to rotate vertically. Since the telescopic rod 6 and the lighting module 5 are installed on the universal ball 7, it is convenient to adjust the angle of the lighting module 5 in the thoracic cavity and improve the lighting efficiency. The telescopic rod 6 uses its own power to adjust the distance between the lighting module 5 and the lesion location. Since the lighting device is built into the thoracic cavity, the interference of external devices is reduced, the surgical operation space is increased, the surgical complexity and patient trauma are reduced, and the surgical efficiency and safety are improved.
