Technical Field

[0001] The present invention relates to the technical field of surgical instrument carts, in particular to a liftable surgical instrument cart. Background Art

[0002] The liftable surgical instrument trolley is an important equipment in modern operating rooms. It is usually made of strong and durable materials, such as stainless steel, and has a stable frame structure. The trolley is equipped with an advanced lifting system, which can easily adjust the height according to different surgical needs and the operating habits of medical staff, providing great convenience for surgical operations. Its multi-layered table and tray can place various surgical instruments, medicines and dressings in an orderly manner, making it convenient for medical staff to use them at any time. The high-quality wheels make the instrument trolley flexible to move, and it is equipped with a reliable brake device to ensure stable parking during the operation.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention sets a lifting mechanism. Conventional lifting devices use hydraulic or pneumatic methods to push the platform to move, thereby achieving lifting. However, the hydraulic system may leak or even get blocked, causing the platform to fall rapidly. The present invention uses a servo motor to drive the lead screw to rotate, thereby driving the moving block to move upward or downward along the lead screw, thereby achieving lifting of the placement unit.

[0017] 2. The present invention provides a fine-tuning mechanism. The medical staff steps on the push pedal to move the round block, the rotating rod and the gear 2 toward the lower gear 1, and make the gear 1 and the gear 2 mesh with each other. Then, the medical staff steps on the rotating pedal on one side with the toes to make the rotating rod and the gear 2 rotate in one direction, thereby driving the gear 1 to rotate and realizing the rotation of the screw rod, and finally moving the placement unit upward or downward, so that slight adjustments can be made.

[0018] 3. The present invention provides an oil replenishing mechanism to clamp wedge block 1 and wedge block 2 together, and then when the push pedal is stepped on to move the rotating rod, the support rod 1, support block 2 and push plate will be driven to move, and the push plate will squeeze out the lubricating oil in the oil storage tank, and the lubricating oil will flow into gear 1 and gear 2 through the through pipe and the nozzle.

[0019] 4. The present invention provides a placement unit. Since the placement table is installed by placing a magnetic ring into a magnetic suspension slot, the magnetic properties of the magnetic suspension slot and the magnetic ring are different. However, since the magnetic ring, the placement table and the objects on the placement table have weight, these weights will be opposite to the repulsion generated by the magnetic force, so that there is a moving space between the magnetic ring and the magnetic suspension slot, which is similar to the state of magnetic suspension. This will facilitate the rotation of the placement table during use and ensure that the placement table can be disassembled at any time for cleaning and disinfection.

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0035] Example 1, using Figure 1-Figure 13 A liftable surgical instrument cart according to an embodiment of the present invention is described as follows.

[0036] like Figure 1-Figure 3 As shown, a liftable surgical instrument vehicle of the present invention comprises a cross plate 1, pulleys 2 are evenly arranged at the bottom of the cross plate 1, the top of the pulley 2 is fixedly connected to the bottom of the cross plate 1, convex plates 3 are evenly arranged at the top of the cross plate 1, the bottom of the convex plates 3 is fixedly connected to the top of the cross plate 1, the bottom of the convex plates 3 is fixedly connected to a telescopic rod 4, the bottom of the telescopic rod 4 is fixedly connected to a chassis 5, the top of the cross plate 1 is fixedly connected to a lifting mechanism 6, the outer surface of the lifting mechanism 6 is fixedly connected to a fine-tuning mechanism 7, the top of the lifting mechanism 6 is fixedly connected to a placement unit 8, and the outer surface of the placement unit 8 is rotatably connected to a cover plate 9;

[0037] When the present invention is working, the placement unit 8 is first placed on the lifting mechanism 6. Under normal conditions, the lifting mechanism 6 will drive the placement unit 8 to be lifted and lowered. During surgery, when the placement unit 8 needs to be lifted and lowered, the telescopic rod 4 will extend downward and lift the entire surgical instrument vehicle upward for a distance, thereby lifting the pulley 2 off the ground. After that, the staff will use their feet to operate the fine-tuning mechanism 7 to control the placement unit 8 to be slightly lifted and lowered.

[0038] like Figure 6-Figure 8 As shown, the fine-tuning mechanism 7 includes a support plate 71, the outer surface of the support plate 71 is fixedly connected with a circular sleeve 72, the inner wall of the circular sleeve 72 is rotatably connected with a rotating rod 73, the end of the rotating rod 73 close to the lifting mechanism 6 is fixedly connected with a gear 2 713, the end of the rotating rod 73 away from the gear 2 713 is fixedly connected with a round block 74, both ends of the round block 74 are fixedly connected with rotating pedals 75, a slide groove 77 is provided on the cross plate 1, the outer surface of the slide groove 77 is slidably connected with a sliding plate 710, the outer surface of the sliding plate 710 is fixedly connected with a pushing pedal 76, the top of the sliding plate 710 is fixedly connected with a telescopic spring 1 711, the bottom of the support plate 71 is fixedly connected with a drooping plate 79, the outer surface of the drooping plate 79 is fixedly connected with a telescopic spring 2 712, and the top of the support plate 71 is fixedly connected with an oil replenishing mechanism 78.

[0039] During surgery, when the height of the placement unit 8 needs to be adjusted, the servo motor 62 driving the screw rod 63 to rotate may easily cause the placement unit 8 to move excessively, requiring slight adjustments.

[0040] Under normal circumstances, due to the elasticity of telescopic spring 2 712, gear 1 66 and gear 2 713 will be separated. When fine-tuning is needed, the medical staff first steps on the push pedal 76 to move the round block 74, the rotating rod 73 and the gear 2 713 toward the lower gear 1 66, and make the gear 1 66 and the gear 2 713 mesh with each other, and then step on the rotating pedal 75 on one side with the toes to make the rotating rod 73 and the gear 2 713 rotate in one direction, thereby driving the gear 1 66 to rotate and realizing the rotation of the screw rod 63, and finally moving the placement unit 8 up or down. After releasing the foot, the elastic force of telescopic spring 2 712 will first move the rotating rod 73 back and separate gear 1 66 and gear 2 713, and then the elastic force of telescopic spring 1 711 and the pulling force of the telescopic spring 1 711 on the other side will cause the round block 74 to rotate and make the rotating pedal 75 horizontal.

[0041] The top of telescopic spring 1 711 is fixedly connected to the bottom of rotating pedal 75 , and the end of telescopic spring 2 712 away from the drooping plate 79 is fixedly connected to the outer surface of pushing pedal 76 , and the top of pushing pedal 76 contacts the side of circular sleeve 72 away from rotating rod 73 .

[0042] like Figure 4-Figure 5As shown, the lifting mechanism 6 includes a cylinder 61, a servo motor 62 is fixedly connected to the bottom of the cylinder 61, a screw rod 63 is fixedly connected to the output end of the servo motor 62, the top of the screw rod 63 is rotatably connected to a top plate 65, a moving block 67 is threadedly connected to the outer surface of the screw rod 63, a gear 1 66 is fixedly connected to the bottom of the screw rod 63, a notch 64 is provided at one end of the cylinder 61 close to the gear 1 66, support columns 68 are evenly provided on the top of the moving block 67, the bottom of the support columns 68 is fixedly connected to the top of the moving block 67, and the top of the support columns 68 is fixedly connected to a magnetic suspension slot 69.

[0043] Conventional lifting devices use hydraulic or pneumatic means to push the platform to move, thereby achieving lifting. However, the hydraulic system may leak or even be blocked, causing the platform to fall rapidly. The present invention uses the servo motor 62 to drive the screw rod 63 to rotate, thereby driving the moving block 67 to move upward or downward along the screw rod 63, thereby achieving the lifting of the placement unit 8.

[0044] The specific workflow is as follows:

[0045] When lifting and lowering before surgery, the servo motor 62 drives the screw rod 63 to rotate, thereby driving the moving block 67 to move up or down along the screw rod 63, thereby driving the top placement unit 8 to move up and down. During surgery, when the height of the placement unit 8 needs to be adjusted, the servo motor 62 drives the screw rod 63 to rotate, which easily causes the placement unit 8 to move excessively and requires slight adjustment. Under normal circumstances, the elasticity of the telescopic spring 2 712 will separate the gear 1 66 from the gear 2 713. When fine-tuning is required, the medical staff first steps on the push pedal 76 to make the round block 74, the rotating rod 73 and the gear 2 713 move upward or downward. 13 moves gear 1 66 downward, and makes gear 1 66 and gear 2 713 mesh with each other, and then steps on the rotating pedal 75 on one side with the toe, so that the rotating rod 73 and gear 2 713 rotate in one direction, thereby driving gear 1 66 to rotate and realizing the rotation of the screw rod 63, and finally moving the placement unit 8 up or down. When the foot is released, the elastic force of the telescopic spring 2 712 will first move the rotating rod 73 back and separate the gear 1 66 and gear 2 713, and then the elastic force of the telescopic spring 1 711 and the pulling force of the telescopic spring 1 711 on the other side will cause the round block 74 to rotate and make the rotating pedal 75 horizontal.

[0046] Example 2, using Figure 1-Figure 13 A liftable surgical instrument cart according to an embodiment of the present invention is described as follows.

[0047] like Fig. 9 and Fig.11As shown, a liftable surgical instrument vehicle of the present invention is based on the first embodiment, and the oil replenishing mechanism 78 includes a support plate 2 781, the inner wall of the support plate 2 781 is fixedly connected with an oil storage bin 782, the top of the oil storage bin 782 is fixedly connected with a pouring port 786, the outer surface of the oil storage bin 782 is fixedly connected with a through pipe 783, the inner wall of the through pipe 783 is evenly provided with a hard film 784, the outer surface of the hard film 784 is fixedly connected to the inner wall of the through pipe 783, the hard film 784 is gathered together when there is no force, and is in a closed state, and the inner wall of the oil storage bin 782 is slidably connected with a connecting mechanism 787.

[0048] After the fine-tuning mechanism 7 has been used for a period of time, lubricating oil needs to be added to gear one 66 and gear two 713 to increase the transmission efficiency. The push plate 7874 will squeeze out the lubricating oil in the oil storage tank 782. When the lubricating oil passes through the through pipe 783, the hard film 784 is gathered together and in a closed state when there is no force on it. Only when the lubricating oil is squeezed will gaps appear in the hard film 784, and then it will flow into gear one 66 and gear two 713 through the nozzle 785 to achieve the lubrication effect.

[0049] like Fig.10 As shown, the connection mechanism 787 includes a support block 7871, the top of the support block 7871 is fixedly connected to a support rod 1 7872, the top of the support rod 1 7872 is fixedly connected to a wedge 1 7873, the inner wall of the oil storage tank 782 is slidably connected to a push plate 7874, the outer surface of the push plate 7874 is fixedly connected to a support rod 2 7875, and the end of the support rod 2 7875 away from the push plate 7874 is fixedly connected to a wedge 2 7876.

[0050] When oil replenishment is needed, pull back the support rod 2 7875 and clamp the wedge block 1 7873 and the wedge block 2 7876 together. Then, when the push pedal 76 is stepped on to move the rotating rod 73, the support rod 1 7872, the support block 7871 and the push plate 7874 will be driven to move. When the rotating pedal 75 is stepped on to rotate the rotating rod 73, the support rod 1 7872 will separate the wedge block 1 7873 from the wedge block 2 7876, thereby not hindering the normal operation of the fine-tuning mechanism 7.

[0051] The bottom of the second support plate 781 is fixedly connected to the top of the first support plate 71, the outer surface of the support block 7871 is fixedly connected to the outer surface of the rotating rod 73, and the wedge block 1 7873 and the wedge block 2 7876 cooperate with each other.

[0052] The outer surface of the top plate 65 is fixedly connected to the inner wall of the cylinder 61 , and the bottom of the cylinder 61 is fixedly connected to the top of the cross plate 1 .

[0053] The gear 1 66 is meshed with the gear 2 713 , and the outer surface of the support plate 1 71 is fixedly connected to the side of the cylinder 61 close to the notch 64 .

[0054] like Figure 12-13 As shown, the placement unit 8 includes a placement table 81, a magnetic ring 82 is fixedly connected to the bottom of the placement table 81, side panels 83 are symmetrically arranged on both sides of the placement table 81, the top of the side panel 83 is fixedly connected to the bottom of the placement table 81, placement bins 84 are evenly arranged on the top of the placement table 81, a support plate three 85 is fixedly connected to the top of the placement table 81, a groove 86 is arranged on the top of the support plate three 85, an ultrasonic device 87 is fixedly connected to the top of the placement table 81, and a filter plate 88 is fixedly connected to the outer surface of the ultrasonic device 87.

[0055] Since the placement table 81 is installed by placing the magnetic ring 82 into the magnetic suspension slot 69, due to the different magnetic properties of the magnetic suspension slot 69 and the magnetic ring 82, but due to the weight of the magnetic ring 82, the placement table 81 and the objects on the placement table 81, these weights will be opposite to the repulsion generated by the magnetic force, so that there is a moving space between the magnetic ring 82 and the magnetic suspension slot 69, which is similar to the state of magnetic suspension. This will facilitate the rotation of the placement table 81 during use, and can also ensure that the placement table 81 can be disassembled at any time for cleaning and disinfection.

[0056] When using the placement unit 8, the surgical instruments to be used will be placed on the placement bin 84 or the side plate 83. In the intervals between uses, the surgical instruments will be placed on the groove 86 of the support plate three 85. The function of the groove 86 is to prevent the instruments from being detached when the table is fine-tuned up and down during surgery. At the same time, the instruments can also be placed on the filter plate 88 of the ultrasonic device 87 for cleaning, which is convenient for subsequent use.

[0057] The outer surface of the magnetic ring 82 is slidably connected to the inner wall of the magnetic suspension slot 69 , and the magnetic properties of the magnetic ring 82 and the magnetic suspension slot 69 are opposite.

[0058] The specific workflow is as follows:

[0059] During operation, after the fine-tuning mechanism 7 has been used for a period of time, lubricating oil needs to be added to the gear 1 66 and the gear 2 713 to increase the transmission efficiency. First, the support rod 1 7872 has a certain elasticity, and the support rod 2 7875 is pulled back to clamp the wedge block 1 7873 and the wedge block 2 7876 together. Then, when the push pedal 76 is stepped on to move the rotating rod 73, the support rod 1 7872, the support block 7871 and the push plate 7874 will be driven to move, and the push plate 7874 will squeeze out the lubricating oil in the oil storage tank 782. When the lubricating oil passes through the through pipe 783, the hard film 784 is gathered together in a closed state when there is no force. The lubricating oil will be squeezed to create a gap in the hard film 784, and then flow through the nozzle 785. When the rotating pedal 75 is stepped on to rotate the rotating rod 73, the supporting rod 1 7872 will separate the wedge 1 7873 from the wedge 2 7876, thereby not hindering the normal operation of the fine-tuning mechanism 7. Finally, since the placement table 81 is installed by placing the magnetic ring 82 into the magnetic suspension slot 69, the magnetic properties of the magnetic suspension slot 69 and the magnetic ring 82 are different, but since the magnetic ring 82, the placement table 81 and the objects on the placement table 81 have weight, these weights will be opposite to the repulsion generated by the magnetic force, so that there is a moving space between the magnetic ring 82 and the magnetic suspension slot 69, which is similar to the state of magnetic suspension. This will facilitate the rotation of the placement table 81 during use, and can also ensure that the placement table 81 can be disassembled at any time for cleaning and disinfection.

[0060] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
