[0002] In the medical field, endoscopic therapy is a common and important diagnostic and treatment method, which requires extremely high functionality and stability of the equipment. Traditional endoscopic therapy carts are mostly designed with fixed structures, and the adjustment functions are complex and limited, which cannot adapt to the quick and convenient adjustment during use. These carts have problems such as inconvenient height and position adjustment, insufficient stability, and excessive space occupation in actual use. Especially when carrying heavy objects, traditional carts often show high stability, but it is challenging to meet the requirements of rapid adjustment while taking into account stability. The pursuit of functional adjustment is bound to affect the safety of operation. In addition, traditional carts often lack flexibility when moving and adjusting positions, resulting in difficulties in operation in a small medical environment. In order to improve these shortcomings, a new type of cart is needed, which is designed to provide higher adjustment flexibility and stability while optimizing space utilization and ease of operation. Therefore, this scheme proposes an endoscopic therapy cart with multi-functional adjustment, pressure control and sliding mechanism, aiming to solve the shortcomings of existing carts and improve the operating efficiency and comfort in endoscopic therapy.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0044] like Figures 1 to 9 As shown, the multifunctional mobile cart for endoscopic treatment includes:

[0045] Two sets of side frames 2 are symmetrically and movably connected on both sides of the load-bearing seat 1, and the top ends of the two side frames 2 on the same side are movably connected to a height adjustment component 6 through a pin shaft;

[0046] A storage platform 8 is fixedly connected below the height adjustment component 6;

[0047] The position retainer 4 is movably connected to the surfaces of the two side frames 2 on the same side through a pin shaft, and a pressure regulator 5 for adjusting the inlet and outlet air pressure in both directions of extension and contraction is provided at the bottom end of the position retainer 4;

[0048] The stand 3 is fixedly connected to one side of the load-bearing seat 1, and is used to cooperate with the load-bearing seat 1 to form a main body support;

[0049] The horizontal slide rail 7 is fixedly connected to the upper surface of the height adjustment assembly 6 , and a storage panel 9 is fixedly connected to the upper surface of the horizontal slide rail 7 . A push-pull opening 13 is provided on the surface of the storage panel 9 .

[0050] Specifically, Figure 3 As shown: the stand 3 includes a column 31 fixedly connected to one side of the load-bearing seat 1, a support 33 is fixedly connected to the surface of the column 31, and a bottom support frame 32 is fixedly connected to the bottom end of the column 31.

[0051] By setting the column 31, the column 31 is directly fixed on one side of the load-bearing seat 1, so that the column 31 has a better supporting effect. At the same time, the platform 33 on the surface can place the debris bucket 10, keep the debris bucket 10 in an independent state, and have a certain height, which is convenient for throwing debris or garbage, and cooperates with the platform 33 to support the weight and facilitate the taking and placing operation.

[0052] Specifically, Figure 7 As shown: the position retainer 4 includes a cylinder 41, the inner wall of the cylinder 41 is movably connected to a piston 42, the surface of the piston 42 is fixedly connected to a telescopic end 43, the telescopic end 43 slides through one end of the cylinder 41, and the end of the cylinder 41 away from the telescopic end 43 is movably connected to the surfaces of the two side frames 2 on the same side through a pin shaft.

[0053] The pressure regulator 5 comprises two gas chambers 52 symmetrically connected and arranged at the bottom end of the cylinder 41, and a connecting rod 51 is axially penetrated and slidably connected to the two gas chambers 52, and an outlet valve core 53 and an inlet valve core 54 are sealably penetrated and slidably connected to the surface of the connecting rod 51;

[0054] The outlet valve core 53 and the inlet valve core 54 are respectively located on the inner wall of the two gas chambers 52 and are fitted together. One end of the connecting rod 51 is threadedly matched with a threaded barrel 58, and the end of the threaded barrel 58 away from the connecting rod 51 is provided with a knob 59.

[0055] The knob 59 on the surface of the threaded barrel 58 is fixedly connected thereto, and the inner wall of the knob 59 arranged at one end of the connecting rod 51 is threadedly matched with one end of the connecting rod 51 through a nut;

[0056] The surface of the air chamber 52 is provided with a vent hole 57 for external air circulation;

[0057] Two first magnets 55 are fixedly connected to the surface of the connecting rod 51 , and a second magnet 56 cooperating with the first magnet 55 is disposed on one side of the inlet valve core 54 and the outlet valve core 53 , and the first magnet 55 and the second magnet 56 are in a repulsive state.

[0058] When in use, the first magnet 55 on the surface of the connecting rod 51 and the threaded tube 58 applies pressure to the second magnet 56 through repulsion, thereby maintaining a holding force on the outlet valve core 53 and the inlet valve core 54. Based on the action of the holding force, the outside airflow needs to lift the inlet valve core 54 when entering, and the internal airflow needs to lift the outlet valve core 53 when being discharged. This process is the process of offsetting the repulsive force of the two first electromagnets and the corresponding second electromagnets respectively. When the placed items are heavier, the pressure of the first magnet 55 on one side can be increased by rotating the threaded sleeve alone. If the weight is lighter, the nut can be rotated to move the connecting rod 51 for adjustment. When the connecting rod 51 moves, the two first magnets 55 on the surface move at the same time, and synchronous adjustment is performed under the premise that the original inlet and outlet air pressure ratio remains unchanged, which is convenient for use.

[0059] Specifically, Figure 3 As shown: rollers 11 are arranged at the four corners of the load-bearing seat 1 and the bottom support frame 32, a handle 12 is fixedly connected to the top of the column 31, and a debris bucket 10 is arranged on the surface of the support platform 33.

[0060] By setting the handle 12, the handle 12 can directly act on the load-bearing seat 1 and the bottom support frame 32 through the column 31 to make them move as a whole. The bottom rollers 11 are respectively installed under the bottom support frame 32 and the load-bearing seat 1 to ensure stability.

[0061] Specifically, Figure 5 As shown: the height adjustment assembly 6 includes a frame plate 61 located at the top of the two sets of side frames 2 and movably connected by a pin shaft. The frame plate 61 is provided with a directional through hole 62 and a plurality of guide holes 64;

[0062] The inner wall of the guide hole 64 is rotatably provided with a threaded rod 65, and the surface of the threaded rod 65 is threadedly matched with a guide block 66, which slides on the inner wall of the guide hole 64, and the upper surface of the guide block 66 is movably connected with a deflection plate 67 through a pin shaft, and the top end of the deflection plate 67 is movably connected to the lower surface of the horizontal slide rail 7 through a pin shaft;

[0063] Vertical through frames 63 are symmetrically and vertically slidably disposed on both sides of the frame plate 61 . The vertical through frames 63 are slidably disposed on the inner walls of the corresponding guide holes 64 .

[0064] By setting up a vertical through-frame 63, the vertical through-frame 63 is fixed between the storage panel 9 and the storage table 8 to keep the distance between the storage panel 9 and the storage table 8 constant. When the height is adjusted in conjunction with the height adjustment component 6, it can slide on the inner wall of the directional through-frame 62 to ensure the stability of lifting and lowering and the constancy of the relative distance.

[0065] The air inlet valve core 54 and the air outlet valve core 53 are both located on the right side of the two air chambers 52, and the two air vents 57 are opened on the side away from the two air chambers 52. The air inlet valve core 54 and the air outlet valve core 53 cooperate with each other to control the gas in and out of the piston 42 in the cylinder 41. The pressure is directly fed back to the size of the supporting force. Through an adjustable method, the overall load-bearing range can be adjusted to meet the needs of use. In normal use, the items placed are all regular and do not need to be adjusted multiple times.

[0066] Specifically, Figure 6 As shown: the horizontal slide rail 7 includes a slide seat 71 fixedly connected to the upper surfaces of the two vertical through frames 63, the top of the deflection plate 67 is movably connected to the lower surface of the slide seat 71 through a pin shaft, and a slide member 72 is slidably provided on the inner wall of the slide seat 71;

[0067] A limiting column 74 for limiting the slide 72 is fixedly connected to the lower surface of the inner wall of the slide 71, and a baffle 75 for cooperating with the limiting column 74 is fixedly connected to the inner wall of the slide 72. Limiting bosses 76 for limiting the slide 72 are symmetrically arranged on both sides of the inner wall of the slide 71, and blocks 77 on the same horizontal plane as the limiting bosses 76 are symmetrically arranged on both sides of the slide 72.

[0068] The slide 72 can slide on the inner wall of the slide seat 71 in two directions. In one direction, the slide 72 is prevented from slipping due to the interference of the baffle 75 and the limit column 74. In the other direction, the limit boss 76 and the stop block 77 cooperate to prevent it from slipping, so that the storage panel 9 can achieve horizontal height displacement adjustment without slipping.

[0069] Specifically, Figure 6 As shown, ball groups 73 that slide in cooperation with the slide seat 71 are arranged on both sides of the slide 72, and the slide 72 is fixedly connected to the lower surface of the storage panel 9.

[0070] By providing the ball group 73 , the slide member 72 can slide on the inner wall of the slide seat 71 to ensure smooth sliding and avoid the overall deviation and tilt caused by friction damping.

[0071] The detailed explanation of this plan is as follows:

[0072] Combined with the actual operation needs of this department, our hospital has specially investigated and developed this device, which basically follows the traditional multi-layer design concept. When in use, heavier equipment is preferably placed directly in the load-bearing seat 1, and the storage table 8 can be used to place heavy objects. The storage panel 9 is used to place, for example, endoscope tubes, instruments and tools, etc. A display needs to be installed on one side of the stand 3 in subsequent use;

[0073] When in use, the two ends of the pressure regulator 5 can be rotated according to the weight requirements of the items in normal use, so that the telescopic force of the position retainer 4 can be adjusted differently. In actual use, after moving to the specified position, the push-pull port 13 can be held to press or lift up to tilt the side frame 2. The tilting spacing of the two side frames 2 on the same side changes, and the position retainer 4 can maintain the spacing between the two side frames 2 to keep the tilt unchanged. At the same time, the storage panel 9 and the storage table 8 can be adjusted along with the front and rear positions, and their heights will also change during the front and rear position pulling and adjustment process. This method can quickly adjust the horizontal position and height of the storage panel 9 and the storage table 8 according to needs, which is convenient for use and can avoid the load-bearing seat 1 from occupying the operating space.

[0074] Furthermore, by rotating the threaded rod 65, the threaded rod 65 rotates and the guide block 66 slides axially on the inner wall of the guide hole 64 under the cooperation of the thread. At this time, the guide block 66 moves and moves the bottom end of the deflection plate 67, and then the top end of the deflection plate 67 lifts the horizontal slide rail 7, so that after it is pulled to a suitable position, the height of the storage platform 8 and the storage panel 9 can be adjusted quickly and separately;

[0075] Furthermore, by directly pushing the storage panel 9 horizontally, the storage panel 9 can slide through the horizontal slide rail 7, and the storage panel 9 and the storage table 8 are in a staggered state, which is convenient for viewing or taking objects in the storage table 8, and can satisfy the operator's ability to pull the storage panel 9 to move with it when moving one side of the bed.

[0076] The overall height is adjusted, and the positions of the stand 3 and the load-bearing seat 1 will not change. The overall movement can only be achieved by moving the roller 11. The roller 11 can be positioned at the designated position when it is braked. If the state is adjusted and you do not want to reset it, you can move the whole thing by holding the handle 12.

[0077] In order to ensure the best push-pull feel and strength, by rotating the knob 59 on the surface of the connecting rod 51 or the threaded barrel 58, the connecting rod 51 is moved synchronously with the threaded barrel 58 under the action of the nut thread, and the two first magnets 55 press the second magnet 56 at the same time. By rotating the threaded barrel 58 alone, the pressing force of the two first magnets 55 on the second magnet 56 can be differentiated, so that the supporting force is greater than the downward force, which can well offset the gravity of the placed items and match the best adjustment operation feel. This method can achieve coordinated control of the inlet and outlet air ratio unchanged after proportional regulation, and is easy to operate.

[0078] In summary, this solution is based on the air pressure control of the magnetic adjustment mechanism, combined with multiple adjustment functions of height, extension, and horizontal position. First, through the repulsive force between the first magnet 55 and the second magnet 56, an efficient and accurate way is provided to control the opening and closing of the air inlet valve core 54 and the air outlet valve core 53. When the weight of the item changes, the user can accurately adjust the magnetic force by turning the threaded sleeve, thereby achieving flexible control of the supporting force and ensuring the stability and safety of the cart under heavy or light conditions. This magnetic-based control method has higher response speed and adjustment flexibility than traditional mechanical structures.

[0079] Secondly, this solution also realizes independent height adjustment and horizontal displacement adjustment of the storage table 8 and the storage panel 9 through the combined design of the threaded rod 65 and the guide block 66. This design enables the device to quickly adapt to different usage scenarios and needs, especially in a medical environment. Through simple operations, medical staff can easily adjust the position and height of the cart, which improves the convenience and flexibility of the operation of the device and reduces the interference caused by physical space limitations on the operation.

[0080] In addition, the design of the roller 11 and the hand-held handle 12 makes the device easier to move, and can quickly lock and unlock the position of the device, adapting to a variety of usage environments. This comprehensive design effectively improves the functionality, ease of operation and safety of the device, and is particularly suitable for medical and other scenarios that require high stability and flexibility of the device.

[0081] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
