Abstract
Description
Technical Field
[0001] This utility model relates to medical equipment, and more particularly to an electric operating table. Background Technology
[0002] An electric operating table is a surgical support device driven by electricity. It mainly includes a headboard, backboard, buttocks board, and legboard. Precise patient positioning is achieved through a hydraulic or mechanical transmission system to meet different positioning needs. The operating table's height is controlled by a lifting cylinder at the bottom that drives the bed to move up and down.
[0003] In existing literature, such as the "Electric Operating Table with Flip-Up Moving Unit" published on March 11, 2022, the tabletop is spaced above the base. A lifting assembly is located between the tabletop and the base. The tabletop can be raised and lowered, rotated 180 degrees horizontally, tilted forward and backward, and tumbled left and right, with the tilting and tumbling linked. The upper surface of the tabletop is provided with a headboard, flip-up moving unit, middle board, legboard, and independent small table. Multiple flip-up moving units are provided on both sides of the middle board, and tabletop frames are provided on both sides of the legboard. In this case, the lifting assembly includes a lifting column mechanism, a tilting motor, a tumbling motor, and a rotating motor. The lifting column mechanism drives the tabletop to rise and fall, the tilting motor drives the tabletop to tilt forward and backward, the tumbling motor drives the tabletop to tumble left and right, and the rotating motor drives the tabletop to rotate 180 degrees horizontally. Most of the space between the bed surface and the base is occupied by the bed lifting mechanism.
[0004] For example, in existing literature, such as the "Intelligent Composite Operating Table" published on January 28, 2025, it includes a base, a lifting support column, and a tilting frame assembly. The tilting frame assembly is equipped with front-to-back tilting frames and left-to-right tilting frames. Two opposite crossbeams of the left and right tilting frames are hinged to the upper end of the lifting support column. The front-to-back tilting frames are fitted outside the left and right tilting frames and hinged to two opposite crossbeams within the left and right tilting frames. A multi-functional bed board is mounted on the front-to-back tilting frames via guide rails. This allows for adjustment of multiple positions of the multi-functional bed board, thereby improving its usability for patients and medical staff and enhancing the convenience and stability of surgical procedures. However, this solution also sacrifices the space between the base and the tilting frame assembly to achieve multi-position adjustment functionality.
[0005] Because the space between the operating table (or frame) and the base is largely occupied, rotation of the operating table is often necessary to complete a comprehensive examination of the corresponding area, such as for procedures like lateral C-arm fluoroscopy. For example, a patent application published on January 11, 2017, entitled "A Rotating Operating Table," includes a lifting operating table, an operating table, and a rotating bearing. The operating table includes a headboard and a backboard. The front end of the backboard has an arc-shaped connecting part, and the bottom end of the headboard has a movable groove. The rotating bearing is located at the front third of the backboard, and its bottom is connected to the lifting operating table. The backboard can rotate horizontally left and right, facilitating lateral C-arm fluoroscopy during surgery. During rotation, not only is a large amount of space required, but the movement can also easily cause patient displacement, necessitating careful stability control.
[0006] In summary, how to increase the space under the backrest on an existing electric operating table with the required specifications and functions to meet the requirements for examinations such as antero-C-arm lateral fluoroscopy is a technical problem that urgently needs to be solved in this case. Utility Model Content
[0007] To address the above problems, this utility model provides an electric operating table with a compact structure that enhances the space under the back panel on existing electric operating tables of various specifications and functions, thereby accommodating examinations such as antero-C-arm lateral fluoroscopy.
[0008] The technical solution of this utility model is: An electric operating table, comprising: The outer frame is slidably mounted between a pair of booms; The inner frame is hinged and can be flipped within the outer frame; along the length of the electric operating table, a hydraulic cylinder mounting position is provided between the inner frame and the outer frame. A lifting mechanism is installed between the base and the inner frame for raising and lowering the height of the boom; A forward and backward tilting linear drive mechanism is provided on the side of the lifting mechanism, with its bottom hinged to the lifting mechanism and its top hinged to the bottom of the inner frame; A left-right tilting linear drive mechanism is located at the cylinder mounting position between the outer frame and the inner frame; one end is hinged to the outer frame, and the other end is hinged to the bottom of the inner frame. The horizontal telescopic linear drive mechanism has a cylinder body fixedly mounted on the outer frame, and the piston rod end is fixedly connected to the inner side of the boom. The horizontal telescopic linear drive mechanism extends and retracts to meet the body part requirements of the inspection equipment.
[0009] Specifically, the bottom corner of the inner frame is provided with a fixed connection combination seat; The combined connecting seat has a first hinge position for the left and right tilting linear drive mechanism (600) at one end and a second hinge position for the front and rear tilting linear drive mechanism at the other end.
[0010] Specifically, the pair of booms are connected by a top support plate.
[0011] Specifically, the outer frame is slidably connected to the inner wall of the boom via a pair of guide rails.
[0012] Specifically, the tilting linear drive mechanism includes a tilting hydraulic cylinder, a tilting air cylinder, or a tilting electric push rod.
[0013] Specifically, the left and right tilting linear drive mechanism includes a left and right tilting hydraulic cylinder, a left and right tilting air cylinder, or a left and right tilting electric push rod.
[0014] Specifically, the horizontal telescopic linear drive mechanism includes a horizontal hydraulic cylinder, a horizontal air cylinder, or an electric push rod.
[0015] Specifically, the lifting mechanism includes: The lifting linear drive mechanism is hinged at the top to the inner frame and at the bottom to the base. The lower column is sleeved on the lifting linear drive mechanism, and its bottom is fixedly connected to the base. The upper column is sleeved on the outside of the lower column, and the top of the inner cavity is fixedly connected to the cylinder of the lifting linear drive mechanism; the inner frame is hinged to the outside of the upper column.
[0016] Specifically, the lifting linear drive mechanism includes a lifting cylinder, a lifting hydraulic cylinder, or a lifting electric push rod.
[0017] Specifically, the piston rod end of the lifting linear drive mechanism is hinged to the base, and the cylinder is hinged to the upper column.
[0018] This invention utilizes a frame structure design (i.e., an outer frame and an inner frame), with the inner frame hinged to the outer frame and a hydraulic cylinder mounting position between them. This effectively utilizes the length of the operating table and reduces the space occupied by the bed lifting components in traditional designs. The horizontal telescopic linear drive mechanism allows the boom to be extended and adjusted, meeting the examination needs of different body parts without requiring the entire operating table to be rotated, thus avoiding the patient position shift problem caused by rotation in traditional solutions. In surgeries requiring frequent position adjustments (such as complex surgeries requiring imaging examinations), this significantly reduces position adjustment time and improves surgical efficiency.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] The following is for reference. Figure 1-6 Describe this utility model; An electric operating table, comprising: The outer frame 100 is slidably disposed between a pair of booms 200; the boom 200 in this case is a back plate boom, used to support the back plate. One end of the back plate boom is equipped with a head plate boom, and the other end is equipped with a waist plate boom. The back plate, head plate, waist plate, push plate, etc. are the same as the existing technology structure. The inner frame 300 is hinged and can be flipped within the outer frame 100; along the length of the electric operating table, a hydraulic cylinder mounting position is provided between the inner frame 300 and the outer frame 100. A lifting mechanism 400 is disposed between the base 800 and the inner frame, and is used to raise and lower the height of the boom 200. A forward and backward tilting linear drive mechanism 500 is disposed on the side of the lifting mechanism 400, with its bottom hinged to the lifting mechanism and its top hinged to the bottom of the side plate of the inner frame 300. A left-right tilting linear drive mechanism 600 is installed at the cylinder mounting position between the outer frame 100 and the inner frame 300; one end is hinged to the outer frame 100, and the other end is hinged to the bottom of the side plate of the inner frame 300. The horizontal telescopic linear drive mechanism 700 has a cylinder body fixedly mounted on the outer frame 100, and the piston rod end is fixedly connected to the inner side of the boom 200. The horizontal telescopic linear drive mechanism 700 can extend and retract to meet the body part requirements of the inspection equipment. The extension range of the horizontal telescopic linear drive mechanism 700 is 460-810mm.
[0024] This design utilizes a frame structure (outer frame 100 and inner frame 300), with the inner frame 300 hinged within the outer frame 100 and a hydraulic cylinder mounting position between them. This effectively utilizes the length of the operating table and reduces the space occupied by the bed lifting components in traditional designs. The horizontal telescopic linear drive mechanism allows for the extension and adjustment of the boom, enabling examinations of different body parts without rotating the entire operating table, thus avoiding patient position shifts caused by rotation in traditional solutions. In surgeries requiring frequent position adjustments (such as complex surgeries requiring imaging examinations), this significantly reduces adjustment time and improves surgical efficiency.
[0025] The piston rod ends of the left-right tilting linear drive mechanism 600 and the front-back tilting linear drive mechanism 500 are hinged to the combined connecting seat 310, thereby extending the left-right tilting linear drive mechanism 600 in the width direction of the electric operating table and the front-back tilting linear drive mechanism 500 in the length direction of the electric operating table. The left-right tilting linear drive mechanism 600 is located above the front-back tilting linear drive mechanism 500, which is tilted to the side of the lifting mechanism 400. This satisfies the front-back and left-right tilting functions while reducing the space around the lifting mechanism 400 (i.e., the space below the back panel). Simultaneously, the front-back and left-right tilting linear drive mechanisms control tilting movements in different directions, achieving not only precise adjustment in multiple positions but also improving the stability of the operating table during operation.
[0026] The bottom corner of the inner frame 300 is provided with a fixed connection combination seat 310; The combined connecting seat 310 has a first hinge position for the left-right tilting linear drive mechanism 600 at one end and a second hinge position for the front-back tilting linear drive mechanism 500 at the other end. By setting the combined connecting seat 310 at the bottom corner of the inner frame 30, the hinge positions of the left-right tilting and front-back tilting drive mechanisms are integrated into the same component, reducing the space occupied by the dispersed hinge points in traditional designs and improving the utilization rate of the operating space under the frame. In this case, the combined connecting seat 310 has an F-shaped cross-section, and the hinge position layout makes the transmission of driving force more balanced, effectively dispersing the local stress when the frame is under load and extending the service life of key components.
[0027] A pair of booms 200 are connected by a top support plate, that is, the support plate is fixedly set on the top surface of a pair of booms 200.
[0028] The outer frame 100 is slidably connected to the inner wall of the boom 200 via a pair of guide rails.
[0029] The tilting linear drive mechanism 500 includes a tilting hydraulic cylinder, a tilting air cylinder, or a tilting electric push rod.
[0030] The left and right tilting linear drive mechanism 600 includes a left and right tilting hydraulic cylinder, a left and right tilting air cylinder, or a left and right tilting electric push rod.
[0031] The horizontal telescopic linear drive mechanism 700 includes a horizontal hydraulic cylinder, a horizontal air cylinder, or an electric push rod.
[0032] The lifting mechanism 400 includes: The lifting linear drive mechanism 410 is hinged at the top to the inner frame 300 and at the bottom to the base 800. The lower column 420 is sleeved on the lifting linear drive mechanism 410, and its bottom is fixedly connected to the base 800. The upper column 430 is sleeved on the outside of the lower column 420, and the top of the inner cavity is fixedly connected to the cylinder of the lifting linear drive mechanism 410; the inner frame 300 is hinged to the outside of the upper column 430.
[0033] The lifting linear drive mechanism 410 includes a lifting cylinder, a lifting hydraulic cylinder, or a lifting electric push rod.
[0034] The piston rod end of the lifting linear drive mechanism 410 is hinged to the base 800, and the cylinder is hinged to the upper column 430.
[0035] The lifting linear drive mechanism 410 in this case is equipped with a metal dust cover 900 on the outside. The cylinder of the tilting linear drive mechanism 500 is located inside the metal dust cover 900. The piston rod extends out from inside the metal dust cover 900 and is protected from dust by a corrugated rubber hose telescopic sleeve 910, which effectively improves the convenience and service life of the operating table for disinfection and cleaning.
