Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a surgical lighting device with a resetting function. Background Technology

[0002] Surgical lighting devices are used to illuminate the surgical site for optimal observation of small, low-contrast objects at different depths within incisions and body cavities. They primarily utilize the multi-point light source effect: when multiple light sources illuminate an object, some light sources are blocked by the object and cannot reach the receiving surface, creating shadows. Meanwhile, light from other light sources illuminates this shadowed area from another angle, thereby reducing and eliminating the shadow in this area, ultimately forming a shadowless zone. Furthermore, if the shadowless lamp malfunctions, a reset operation can be attempted to restore it to normal working condition.

[0003] Existing surgical lighting devices use a crossarm to allow the operator to move the lamp head to the desired position, facilitating observation of the surgical incision during surgery. Installation of the crossarm and connector involves engaging the mounting end of the crossarm with the mounting point of the connector, rotating the crossarm or connector according to pre-drilled holes at the engagement point to align multiple holes, and then inserting bolts to complete the installation. However, the alignment of these mounting holes during installation can cause obstruction, resulting in installation difficulties. Utility Model Content

A connection is provided between the connecting seat 32 and the lamp head 1. A cross arm 2 is provided, and a limiting component 30 is provided between the cross arm 2 and the connecting seat 32. The limiting component 30 consists of a movable cavity 301, a connecting component 302, a limiting block 303, and a groove component 304. The movable cavity 301 is opened inside the connection between the connecting seat 32 and the cross arm 2. The limiting block 303 is disposed inside the movable cavity 301. The connecting component 302 is disposed at the connection between the bottom end of the limiting block 303 and the bottom end of the movable cavity 301. The groove component 304 consists of a sliding groove 3041 and a retaining groove 3042. The slide groove 3041 is located at the bottom edge of the inner wall of the horizontal arm 2, and the slot 3042 is located on the inner side of the horizontal arm 2. The bottom end of the slot 3042 is connected to the top end of the slide groove 3041. The designed limiting component 30 improves the problem that, in the original surgical lighting device, when aligning multiple mounting holes between the horizontal arm 2 and the base 3 during installation, the mounting holes would be obstructed, causing inconvenience in alignment and affecting installation efficiency. This is achieved by setting a limiting component 30 at the connection between the horizontal arm 2 and the base 3. The positioning component 30, during installation, limits the position of the mounting hole to increase installation efficiency. The cross-section of the slide 3041 is L-shaped, and the cross-section of the limiting block 303 is L-shaped. The depth of the slide 3041 is half the thickness of the connecting seat 32. The connection between the cross arm 2 and the connecting seat 32 is provided with a mounting hole, and a bolt passes through the inner side of the mounting hole. An operator is provided on the side of the lamp head 1, and a disinfection handle is provided on the lamp head 1. The disinfection handle facilitates the operator to move the lamp head 1.

[0022] In this embodiment, preferably, the connecting component 302 consists of a crossbar 3021 and a torsion spring 3022. The crossbar 3021 is located inside the bottom end of the limiting block 303. Both ends of the crossbar 3021 are fixed to the inner walls of the movable cavity 301. The connecting component 302 enables the bottom end of the limiting block 303 to be movably connected to the movable cavity 301. The torsion spring 3022 is sleeved on the surface of the crossbar 3021. Both ends of the torsion spring 3022 are fixed to the inner side of the limiting block 303. The crossbar 3021 has a cylindrical structure.

[0023] The working principle and usage process of this utility model are as follows: During surgery, when multiple light sources on lamp head 1 illuminate an object, the light from some light sources will be blocked by the object and cannot reach the receiving surface, creating a shadow. Meanwhile, the light from other light sources will illuminate this shadowed area from another angle, thereby reducing and eliminating the shadow, ultimately forming a shadowless zone. This shadowless design provides a clear surgical field of vision, ensures surgical safety, meets surgical needs, and protects the surgeon's eyes. When the lighting device malfunctions, a reset operation can be attempted to restore normal operation. The specific reset steps are as follows:

[0024] 1. Check the power supply: Confirm that the power supply of the surgical shadowless lamp is normal, including checking the power plug, power cord and power switch, etc.

[0025] 2. Replace the monitor for testing: Try replacing it with a known working monitor to determine if the problem is with the original monitor itself. If the problem is solved after replacement, it means that the original monitor is faulty and needs to be repaired or replaced.

[0026] 3. Check the grounding connection: Confirm that the grounding connection is secure and free from looseness or corrosion. Use a multimeter to test the grounding resistance, ensuring the resistance is within a reasonable range. If the grounding resistance is too high, try cleaning the rust from the grounding connector and reinforcing the grounding connection with a suitable conductive material.

[0027] 4. Check the magnetron and modulator: Place a microphone or other sound detection tool around the magnetron and listen for any abnormal sounds when the beam is emitted to determine if the magnetron is arcing. If a problem with the magnetron is confirmed, the modulator settings may need to be adjusted.

[0028] V. Systemic Fault Troubleshooting: Try resetting the surgical shadowless lamp system to see if it can be restored to normal.

[0029] By following the steps above, you can try resetting the shadowless lamp to troubleshoot the problem and restore it to normal operation. If the problem persists, it is recommended to contact a professional repair technician for further inspection and repair.

[0030] When it is necessary to install the cross arm 2 and the connecting seat 32, first press the top of the limiting block 303, so that the limiting block 303 rotates inward around the through cross bar 3021. During the rotation, the torsion spring 3022 deforms. Then, align the top of the limiting block 303 with the slide groove 3041, and simultaneously insert the mounting end of the cross arm 2 into the inner side of the mounting end of the connecting seat 32, and at the same time, insert the top of the limiting block 303 into the inner side of the slide groove 3041. After the top of the mounting end of the cross arm 2 is inserted into the inner side of the top of the mounting end of the connecting seat 32, the limiting block 303... The top of the limit block 303 is inserted into the top of the slide groove 3041. Then, the cross arm 2 or the connecting seat 32 is rotated, causing the top part of the limit block 303 to rotate inside the top of the slide groove 3041. When the top of the limit block 303 is aligned with the slot 3042, under the torque of the torsion spring 3022, the top part of the limit block 303 is engaged inside the slot 3042, thus limiting the connection between the cross arm 2 and the connecting seat 32. At the same time, the mounting holes between the cross arm 2 and the connecting seat 32 are aligned. Then, the bolt is passed through the mounting hole to complete the installation operation of the cross arm 2 and the connecting seat 32.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
