Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a surgical shadowless lamp lifting device. Background Technology

[0002] A shadowless lamp is an effect produced by a group of lights working together. It can increase brightness and eliminate shadows during operation. A shadowless lamp arranges high-intensity light sources in a circle on a large lamp panel, allowing the light to shine down from different angles, so the shadows formed by each point light source are not visible. Shadowless lamps are mainly used in medical institutions such as hospitals and beauty salons.

[0003] Currently, operating lights on the market are mainly divided into two categories. The first type is the fixed operating light, which is installed on the ceiling of the operating room. Its biggest advantage is that it does not occupy horizontal space, allowing doctors and nurses to move freely and operate flexibly around the operating table. However, this type of operating light has obvious limitations. Because it cannot be moved, it can only be used in the operating room and cannot meet the lighting needs of surgeries in other locations. The other type is the portable operating light, which mainly consists of a lifting device and the operating light body. When in use, the height and angle need to be manually adjusted. It has a high degree of flexibility and can not only serve as an emergency backup lighting device when the fixed operating light fails, but is also suitable for temporary or simple surgical environments.

[0004] In practical clinical applications, portable shadowless lamps have significant drawbacks in terms of ease of operation. Height adjustment requires medical staff to directly pull the lamp body. Especially when medical staff are too short to reach the adjustment components, not only is it impossible to quickly adjust the lighting angle and height, but repeated attempts to adjust may also prolong surgical preparation time, severely impacting surgical efficiency and quality. This highly manual operation mode significantly affects the convenience of using shadowless lamps. Utility Model Content

[0005] To address the problem that existing surgical shadowless lamps rely on manual height adjustment, this invention provides a surgical shadowless lamp lifting device.

[0006] This utility model is achieved through the following technical solution:

[0007] A surgical shadowless lamp lifting device includes a movable base and a lifting mechanism. The lifting mechanism includes a square tube vertically mounted on the top of the movable base. One side of the square tube has an elongated hole. A fixed frame is installed at the bottom inside the square tube. A rotating shaft is rotatably connected to the inside of the fixed frame. A reducer and a motor are connected and driven on the fixed frame. The output shaft of the reducer is driven by the rotating shaft. A pulley is rotatably connected to the top inside the square tube. A rope is wound around the rotating shaft. The rope passes around the pulley and connects to a lifting frame that slides and guides against the inner wall of the square tube. A connecting plate that slides and guides against the elongated hole is connected to the lifting frame. Several connecting rods are rotatably connected to the connecting plate via an angle adjustment mechanism. The shadowless lamp can be connected and installed with the connecting rods located away from the connecting plate.

[0008] A further improvement of this invention is that the angle adjustment mechanism is a damping shaft, which can fix the angle of the connecting rod, thus maintaining the connecting rod at the required rotation angle.

[0009] A further improvement of this invention is that a counterweight is provided inside the movable base. This lowers the center of gravity and prevents the shadowless lamp from tipping over during use.

[0010] A further improvement of this invention is that a handle is installed on the side of the square tube, and a control panel is also provided on the side. The control panel is electrically connected to the shadowless lamp and the motor. The handle provides the operator with a point of leverage to move the device, facilitating pushing and pulling to adjust the appropriate angle. The control panel can control the on / off state and brightness of the shadowless lamp, as well as the raising and lowering of the device.

[0011] A further improvement of this utility model is that the connecting rod includes a telescopic tube and a telescopic rod slidably inserted into the telescopic tube. The telescopic rod has several arrayed second limiting grooves on its side. The telescopic tube has a second through hole at one end near the telescopic rod. A fixing box is connected and installed on the outside of the second through hole. A telescopic block that passes through the second through hole and can engage with the second limiting groove is installed inside the fixing box. A spring block installed in the fixing box is connected to the side of the telescopic block away from the telescopic rod.

[0012] A further improvement of this invention is that the connecting rod is a hollow, lightweight aluminum alloy rod. This reduces the weight of the connecting rod, making it easier and less strenuous to adjust the angle of the shadowless lamp.

[0013] A further improvement of this invention is that tapered plates are connected and installed on both sides of the rotating shaft. This guides the rope towards the center, ensuring that the vertical portion of the rope is in the middle position and guaranteeing smooth sliding of the rope within the first through hole.

[0014] A further improvement of this invention is that several hooks are provided on the upper side wall of the square tube, which allows for the hanging of IV bags for patients during surgery.

[0015] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0016] When using this device, first push the device to the surgical area via the movable base, start the motor to drive the shadowless lamp to rise and fall smoothly along the vertical guide rail to the appropriate height, ensuring that the shadowless lamp maintains a stable posture without external interference, providing the surgeon with the necessary space to adjust the illumination height and angle. After the surgery, quickly raise the shadowless lamp to immediately release the surgical field of view, leaving ample space for subsequent medical operations such as postoperative care and patient transfer, significantly improving the efficiency of the entire surgical process.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0028] As shown in the figure, this utility model discloses a surgical shadowless lamp lifting device, including a movable base 1, a lifting mechanism 2, and a connecting rod 3. The lifting mechanism 2 includes a square tube 201 vertically mounted on the top of the movable base 1. One side of the square tube 201 has an elongated hole 202. A fixed frame 203 is connected and installed on the inner side of the bottom of the square tube 201 away from the elongated hole 202. A rotating shaft 204 is rotatably connected to the inner side of the fixed frame 203. A worm gear reducer 205 with a transmission connection is connected and installed on the fixed frame 203. The output shaft of the reducer 205 is transmissionally connected to the rotating shaft 204. A motor 206 is driven and installed at the upper end of the reducer 205. A pulley 209 is connected and installed at the top of the inner end of the square tube 201. The pulley 209 can also be installed... On the mounting plate 207 fixed to the top of the square tube 201, the lower end face of the mounting plate 207 is provided with two parallel vertical plates 208 for the pulley 209 to be installed and rotated. A rope 210 is wound on the rotating shaft 204. The rope 210 can be made of steel or nylon, etc. The rope 210 passes around the pulley 209 and is connected to a lifting frame 211 that slides and guides with the inner wall of the square tube 201. The lifting frame 211 is provided with a first through hole 212 for the rope 210 to pass vertically. The lifting frame 211 is provided with a connecting plate 213 that slides and engages with the elongated hole 202. The connecting plate 213 is rotatably connected to the connecting rod 3 through an angle adjustment mechanism. The end of the connecting rod 3 away from the connecting plate 213 is connected to and installed with a shadowless lamp.

[0029] In use, the device is moved to the designated position using the movable base 1. The motor 206 is started, and the reducer 205 causes the rotating shaft 204 to rotate, causing the rope 210 to wind around the rotating shaft 204. The direction of the rope movement is changed by the pulley 209, and the rope 210 pulls the lifting frame 211 up and down. The lifting frame 211 slides stably and vertically on the inner wall of the square tube 201. Due to the worm gear structure of the reducer 205, the rotating shaft 204 can be fixed when the motor 206 is not working, so that the lifting frame 211 maintains a fixed height. When it needs to be moved, the lifting frame 211 is raised to a high position, and the connecting rod 3 is brought close to the square tube 201. On the one hand, this can lower the center of gravity to the lowest level and prevent overturning during movement. On the other hand, it can reduce the carrying space and prevent collision with other objects during movement. After arriving at the operating room, the connecting rod 3 is unfolded, and the angle adjustment mechanism keeps the various connecting rods at the adjusted angle. At the same time, the height is lowered so that the shadowless lamp is in a position for further adjustment by the doctor.

[0030] In one embodiment, the angle adjustment mechanism is a damping shaft, which allows the connecting rod 3 to maintain its current angle without external force, ensuring that the shadowless lamp is at the optimal illumination angle, providing the doctor with a clear field of vision, and ensuring the smooth progress of the surgery.

[0031] In another embodiment, the angle adjustment mechanism includes a bolt 54, a nut 55, a plurality of first limiting blocks 51 arranged in a circular array on one side and a plurality of second limiting blocks 52 arranged on the other side, and a self-locking plate 53 with a connecting hole in the middle. The top of the first limiting block 51 is an arc surface. The connecting surfaces of the connecting plate 213 and the end of the connecting rod 3 are provided with connecting holes and first limiting grooves 56 of the same shape and number as the second limiting blocks 52. The second limiting blocks 52 are embedded in the first limiting grooves 56. The self-locking plate 53 is in close contact with the connecting surface. The bolt 54 is threadedly connected to the nut 55 through the connecting rod 3, the two paired self-locking plates 53 and the connecting hole of the connecting rod 3 on the other side. In use, the self-locking plate 53 and the corresponding connecting rod 3 are kept circumferentially fixed. Under the tightening force of the bolt 54 and nut 55, the first limiting blocks 51 of the paired self-locking plates 53 are engaged with each other. Since the top of the first limiting block 51 is arc-shaped, when subjected to a large torque, the paired first limiting blocks 51 will deform and slide relative to each other, causing the connecting rod 3 to rotate and achieve the purpose of adjusting the angle. As a wear-prone part, the self-locking plate 53 can be repaired and replaced before the angle adjustment function fails, without having to replace the entire connecting rod 3, which has good economic efficiency.

[0032] The bolt 54 has a knob 541 with anti-slip protrusions around its circumference at one end, and the nut 55 has anti-slip protrusions on its outer circumference. The knob 541 has a large diameter, which makes it easier to turn, and it has teeth on the outside, which can enhance the contact friction and provide a large clamping force to the self-locking plate 53, preventing the angle adjustment mechanism from failing due to insufficient clamping force.

[0033] The movable base 1 is equipped with a counterweight 11. The large weight of the counterweight 11 and its low position can lower the center of gravity of the device, making the device more stable during the movement and adjustment of the connecting rod 3.

[0034] The square tube 201 has handles 2011 and control panel 2012 installed on both sides. The control panel 2012 is electrically connected to the shadowless lamp and the motor 206. The handles 2011 provide a fulcrum for moving and transporting the device, facilitating movement. The control panel 2012 contains a controller that is connected to the power supply via wires. The controller is also connected to the motor 206 via wires, which are arranged inside conduits on the side wall to prevent interference with the lifting frame 211. The wires connecting the controller and the shadowless lamp pass through the inner wall of the connecting rod 3. When passing through the angle adjustment mechanism, the wires need to go around to the outside, with a certain redundant length to facilitate adjustment of the angle of the connecting rod 3. The wires pass through the bottom of the lifting frame 211, so that the wires rise and fall with the lifting frame 211, ensuring the power supply.

[0035] Among them, any one of the several connecting rods 3 includes a telescopic tube 41 and a telescopic rod 42 slidably inserted into the telescopic tube 41. The telescopic rod 42 is provided with several arrayed second limiting grooves 43 on its side. The end of the telescopic tube 41 near the telescopic rod 42 is provided with a second through hole 45. A fixing box 44 is connected and installed on the outside of the second through hole 45. A telescopic block 46 is slidably installed inside the fixing box 44, with one side passing through the second through hole 45. A spring block 47 installed inside the fixing box 44 is connected to the side of the telescopic block 46 away from the telescopic rod 42. The telescopic tube 41 can slide on the outside of the telescopic rod 42 to extend the length of the connecting rod 3. The telescopic block 46 inside the fixed box 44 is tightly pressed against the second limiting groove 43 by the elastic force of the spring block 47, so that the telescopic tube 41 can remain relatively fixed with the telescopic rod 42 without a large pulling force. Since the telescopic rod 42 has a groove with a straight wall on one side close to the second limiting groove 43 on the side near the telescopic tube 41, the telescopic block 46 cannot continue to slide away from the telescopic rod 42 after sliding into the groove, so it can prevent the telescopic tube 41 from falling out of the telescopic rod 42 during the process of extending the connecting rod 3.

[0036] The connecting rod 3 is a hollow, lightweight aluminum alloy rod. This significantly reduces the weight of the connecting rod 3, making adjustment easier, lowering the center of gravity, and making the device more stable. The hollow structure also allows the wires to pass through it.

[0037] Among them, the self-locking plate 53 is made of polytetrafluoroethylene (PTFE). PTFE has excellent lubrication and wear resistance, which can increase the service life and smoothness of the angle adjustment mechanism.

[0038] The rotating shaft 204 has tapered plates 2041 connected and installed on both sides. The tapered plates 2041 can provide a center-directing guide for the rope 210 as it is wound on the rotating shaft 204, so that the rope 210 is in the middle position of the rotating shaft 204, keeping the rope 210 in a relatively vertical state, and reducing the contact friction between the rope 210 and the first through hole.

[0039] The square tube 201 has several hooks 2013 on its upper side wall, which can hang items such as infusion bags, improving convenience.

[0040] The controller can be a common PLC controller, such as the Mitsubishi FX5U series. Through programming, the shadowless lamp can be raised and lowered with a single button to reach a preset position. It can be customized according to different doctors' operating habits for ease of operation. Motor 206 uses a DC worm geared motor, model WS-4058GW-555R, which is self-locking; when motor 206 is not rotating, the shaft 204 is locked to prevent rotation.

[0041] It should be noted that the weight of the lifting frame 211 of the surgical shadowless lamp lifting device is sufficient to prevent the lifting frame 211 from moving upward due to the rotation of the connecting rod 3 during the adjustment of the angle of the connecting rod 3, thus affecting the adjustment of the angle of the shadowless lamp.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
