Description

Technical Field

[0001] This utility model relates to a shadowless lamp, and more particularly to a shadowless lamp for use in operating rooms in the field of medical devices. Background Technology

[0002] Surgical shadowless lamps are used to illuminate the surgical site for optimal observation of small, low-contrast objects at different depths within incisions and body cavities. Since the surgeon's head, hands, and instruments can all cast interfering shadows on the surgical site, surgical shadowless lamps should be designed to minimize shadows and reduce color distortion to a minimum.

[0003] Chinese Patent Publication No. CN219222276U discloses a surgical shadowless lamp with lighting adjustment function. This utility model uses a rotating adjustment component. As it rotates, the rotating ball and the connecting sleeve fit more tightly, thereby increasing the friction and making it more stable in use.

[0004] Chinese Patent Publication No. CN222123074U discloses a portable surgical light without shadow. This utility model allows for adjustment of the height of the sliding column, achieving automatic adjustment of the overall height of the base and reducing the labor intensity of the operator.

[0005] During surgery, shadows are minimized by adjusting the angle of the shadowless lamp. However, new shadows are inevitably created when medical staff move around and operate. Since the main light source has a single direction of illumination, either dual shadowless lamps are set up to illuminate the operating table from different directions, or the angle of the shadowless lamps is adjusted to illuminate the shadowed areas. However, the design of dual shadowless lamps greatly increases the cost, and frequent adjustments to the angle of the shadowless lamps may interfere with the surgical procedure. Utility Model Content

[0006] The technical problem that this utility model aims to solve in response to the above-mentioned prior art is that after adjusting the angle of the shadowless lamp, new shadows will be generated when medical staff walk and operate. The dual shadowless lamp design increases maintenance costs, and frequent adjustment of the angle of the shadowless lamp may interfere with the operation of medical staff.

[0007] To address the aforementioned problems, this utility model provides a shadowless lamp for operating rooms, comprising a lamp body, a mounting ring fixedly fitted onto the outer surface of the lamp body, multiple mounting grooves carved into the upper end of the mounting ring, a magnetic block fixedly connected to the inner wall of the mounting groove, a connector fixedly embedded in the surface of the magnetic block, multiple auxiliary lamps externally provided on the lamp body, an adjusting rod fixedly connected to the upper end of each auxiliary lamp, a snap-fit ​​assembly fixedly connected to the end of the adjusting rod away from the auxiliary lamp, the snap-fit ​​assembly being inserted into an adjacent mounting groove, the snap-fit ​​assembly including a locking block fixedly connected to the end of the adjusting rod away from the auxiliary lamp, the locking block... Inserted into the mounting slot, the end of the locking block near the first magnetic block is fixedly connected to the second magnetic block, the end of the second magnetic block near the first magnetic block is fixedly connected to the second connector, and the end of the locking block away from the first magnetic block is fixedly connected to the adjusting block. A pull plate is provided on the outside of the adjusting block, and two insert rods are fixedly connected to the end of the pull plate near the adjusting block. Two compression springs are fixedly connected to the inner wall of the outer side of the adjusting block, and the ends of the two compression springs away from the inner wall of the adjusting block are jointly fixedly connected to a sliding plate. The ends of the insert rods away from the pull plate move sequentially through the adjacent compression springs, the locking block, and the mounting ring, and the sliding plate is fixedly sleeved on the outer surface of the two insert rods.

[0008] In the aforementioned operating room lighting shadowless lamp, an additional mounting ring is added to the original shadowless lamp body. Through the multi-angle layout of the annular slot, an auxiliary lamp is temporarily added to supplement the light according to the blind spot of the shadowless lamp body, effectively solving the problem of the single direction of the main light source. Without damaging the original structure, it effectively eliminates deep shadows. Compared with adding a new shadowless lamp, the cost of this application is greatly reduced, and it is simple to operate and easy to use.

[0009] As a further supplement to this application, magnetic block one and magnetic block two attract each other, and connector one and connector two fit together.

[0010] As a further supplement to this application, the cross-section of the card block is arc-shaped, and the longitudinal section of the card block is U-shaped. The width of the card slot of the card block is consistent with the distance between the mounting ring and the mounting slot.

[0011] As a further supplement to this application, the outer surface of the skateboard is in contact with the inner wall of the adjustment block, and the end of the skateboard near the block is in contact with the block.

[0012] As a further supplement to this application, multiple mounting slots are arranged in a ring array around the mounting ring, the adjusting rod is made of elastic material, and the adjusting rod has a shape memory alloy inner skeleton.

[0013] As a further supplement to this application, a positioning ring is fixedly connected to the upper end of the mounting ring, and multiple baffles corresponding to multiple mounting slots are rotatably connected to the surface of the positioning ring, with a pull rod fixedly connected to the upper end of the baffles.

[0014] In summary, in practical applications, when supplemental lighting is needed, medical staff can pull the pull plate to move the insertion rod outward, then insert the locking block into the mounting slot. Releasing the pull plate allows the insertion rod to pass through the mounting ring and the locking block. Simultaneously, magnetic block two and magnetic block one attract each other, and connector one and connector two engage, illuminating the auxiliary lamp. Pulling the adjustment rod adjusts the position of the auxiliary lamp, providing supplemental lighting to the operating table. This effectively solves the problem of the main light source's unidirectional nature, effectively eliminating deep shadows without damaging the original structure. Compared to adding a new shadowless lamp, the cost of this application is significantly reduced, and it is simple to operate and easy to use. Attached Figure Description

Detailed Implementation

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figure 1 and Figure 2The diagram shows a shadowless lamp for operating rooms, comprising a lamp body 1. A mounting ring 2 is fixedly fitted onto the outer surface of the lamp body 1, extending the functionality of the lamp body 1 without modifying its main structure. Multiple mounting slots 3 are chiseled at the upper end of the mounting ring 2, each capable of mounting multiple auxiliary lamps 6. These slots are arranged in a circular array around the mounting ring 2, facilitating the installation of auxiliary lamps 6 in different positions according to staff requirements. A magnetic block 4 is fixedly connected to the inner wall of the mounting slot 3, and a connector 5 is fixedly embedded in the surface of the magnetic block 4. The magnetic block 4 and connector 5 enable rapid positioning of the auxiliary lamps 6 and provide a power supply interface.

[0026] Figures 1-4 The diagram shows that the main body 1 of the shadowless lamp has multiple auxiliary lamps 6. An adjustment rod 7 is fixedly connected to the upper end of each auxiliary lamp 6. The adjustment rod 7 is made of an elastic material and contains a shape memory alloy inner skeleton. The shape memory alloy skeleton can be bent to a target angle, and its deformation temperature threshold can be set as needed, such as 35 degrees Celsius. Before adjustment, the shape memory alloy skeleton is in a rigid state. After reaching the temperature threshold, it can be bent. After bending, the body temperature triggers a phase transition of the alloy, locking the shape. Releasing the adjustment rod 7 lowers its surface temperature below the threshold, and the shape memory alloy skeleton switches back to a rigid state. This is existing technology. This will not be elaborated further. To facilitate arbitrary adjustment of the angle of the auxiliary lamp 6, the end of the adjustment rod 7 away from the auxiliary lamp 6 is fixedly connected to a snap-fit ​​component. The snap-fit ​​component is inserted into the adjacent mounting slot 3. The end of the snap block 8 near the first magnetic block 4 is fixedly connected to the second magnetic block 9. The end of the second magnetic block 9 near the first magnetic block 4 is fixedly connected to the second connector 10. The first magnetic block 4 and the second magnetic block 9 attract each other, temporarily fixing the snap-fit ​​component. The first connector 4 is connected to the power controller of the shadowless lamp body 1 through a wire. When the first connector 5 and the second connector 10 are in contact, the circuit can be automatically turned on, and it lights up immediately upon plugging in, effectively reducing additional switching operations.

[0027] Figures 3-5The diagram shows that the snap-fit ​​assembly includes a snap-fit ​​block 8 fixedly connected to the end of the adjusting rod 7 away from the auxiliary lamp 6. The snap-fit ​​block 8 is inserted into the mounting groove 3. The cross-section of the snap-fit ​​block 8 is arc-shaped, and the longitudinal section of the snap-fit ​​block 8 is U-shaped. The width of the snap-fit ​​groove of the snap-fit ​​block 8 is consistent with the distance between the mounting ring 2 and the mounting groove 3, so that the snap-fit ​​block 8 can be stably snapped onto the mounting ring 2. An adjusting block 11 is fixedly connected to the end of the snap-fit ​​block 8 away from the magnet 4. A pull plate 12 is provided on the outside of the adjusting block 11. Two insert rods 13 are fixedly connected to the end of the pull plate 12 near the adjusting block 11. Two compression springs 14 are fixedly connected to the inner wall of the outer side of the adjusting block 11. The two compression springs 14 are located away from the adjusting block 6. A sliding plate 15 is fixedly connected to one end of the inner wall of the block 11. The outer surface of the sliding plate 15 is in contact with the inner wall of the adjusting block 11, and the end of the sliding plate 15 near the locking block 8 is in contact with the locking block 8. The end of the insert rod 13 away from the pull plate 12 moves through the adjacent compression spring 14, the locking block 8 and the mounting ring 2 in sequence. The sliding plate 15 is fixedly sleeved on the outer surface of the two insert rods 13. The medical staff pulls the pull plate 12 to move the insert rod 13 outward, and then the locking block 8 is inserted into the mounting groove 3 in the appropriate position. The pull plate 12 is released so that the insert rod 13 passes through the mounting ring 2 and the locking block 8, thereby limiting and fixing the locking block 8, effectively preventing the auxiliary light 6 from falling off during the operation.

[0028] In use, the shadowless lamp body 1 can be connected to the external mounting bracket. The illumination direction of the shadowless lamp body 1 can be adjusted by adjusting the mounting bracket. When supplementary lighting is needed, an auxiliary lamp 6 can be selected. Medical staff pull the pull plate 12 to move the insertion rod 13 outward, and then insert the locking block 8 into the appropriate mounting slot 3. Release the pull plate 12 so that the insertion rod 13 passes through the mounting ring 2 and the locking block 8. At the same time, the second magnetic block 9 and the first magnetic block 4 attract each other, and the first connector 5 and the second connector 10 fit together. The auxiliary lamp 6 lights up. Pull the adjustment rod 7 to adjust the position of the auxiliary lamp 6. The auxiliary lamp 6 provides supplementary lighting to the operating table, thereby effectively solving the problem of the single directionality of the main light source. Without damaging the original structure, it effectively eliminates deep shadows. Compared with adding a new shadowless lamp, the cost of this application is greatly reduced, and the operation is simple and easy to use.

[0029] Second implementation method:

[0030] This embodiment adds a positioning ring 16, a baffle 17, and a pull rod 18 to the first embodiment, while the rest remains the same as the first embodiment.

[0031] Figure 6 As shown: A positioning ring 16 is fixedly connected to the upper end of the mounting ring 2. Multiple baffles 17, each corresponding to a multiple mounting slot 3, are rotatably connected to the surface of the positioning ring 16. A pull rod 18 is fixedly connected to the upper end of the baffle 17. The pull rod 18 facilitates the operation by allowing medical staff to pull the baffle 17.

[0032] Multiple baffles 17 are used to shield multiple mounting slots 3, thereby effectively protecting the magnetic block 4 and connector 5 inside the mounting slot 3 and effectively reducing the entry of external substances into the mounting slot 3.

[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
