Description

Technical Field

[0001] This utility model belongs to the field of operating table technology, specifically relating to a mechanism for realizing the up-and-down bending of the electric legs of the operating table by 90° and the operating table itself. Background Technology

[0002] In lumbar surgeries such as kidney and ureter surgery, the lateral decubitus position, as well as gynecological laparoscopic surgeries, require the operating table's legboard to fold down to facilitate the procedure. Electric operating tables have a legboard folding mechanism that can fold the legboard down to a angle of 90° or greater, but the legboard folding angle is generally between 15° and 20°, and the upward folding angle is small, which cannot meet the requirements of special surgeries. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a mechanism that enables the electric leg of the operating table to bend vertically by 90°. This mechanism can bend upwards by 90° and downwards by more than 90°, providing a better and safer experience for surgical patients, while also facilitating operation by medical staff.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mechanism for achieving 90° vertical bending of an electric leg plate on an operating table, the mechanism comprising a leg plate connecting frame, a seat plate frame, a drive component, a fan blade, a first leg plate connecting rod, and a second leg plate connecting rod;

[0006] One end of the drive component is hinged to the seat plate frame, and the other end is hinged to the middle part of the second leg plate connecting rod.

[0007] One end of the second leg plate connecting rod is hinged to the seat plate frame, and the other end is hinged to one end of the first leg plate connecting rod; the other end of the first leg plate connecting rod is hinged to the leg plate connecting frame.

[0008] The leg plate connecting frame and the seat plate frame are connected by a hinge.

[0009] The fan blade is a 100° sector-shaped plate with a limiting groove along the arc of the fan blade. A limiting post is set on the leg plate connecting frame, and the limiting post is locked in the limiting groove. The center of the fan blade is hinged to the hinge axis between the leg plate connecting frame and the seat plate frame.

[0010] Furthermore, a limiting block is provided on the fan blade, and a limiting block matching the limiting block is provided on the seat plate frame to prevent the fan blade from being pulled out of the leg plate frame by external force.

[0011] Preferably, the first leg plate connecting rod is S-shaped and the second leg plate connecting rod is arc-shaped.

[0012] This utility model also provides an operating table, which is equipped with the above-mentioned mechanism that enables the electric legs of the operating table to bend up and down by 90°.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention allows for a larger upward folding angle, meeting the needs of special surgical positions; the connecting rod structure has higher strength and a stronger load-bearing capacity. This invention also features a large-angle upward folding protective fan to prevent injury from accidental operation. Attached Figure Description

[0021] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] like Figure 1-2 As shown, a mechanism for realizing the up-and-down bending of the electric leg plate of the operating table by 90° is provided. The mechanism includes a leg plate connecting frame 1, a seat plate frame 2, a fan plate 3, a driving component 4, a first leg plate connecting rod 5, and a second leg plate connecting rod 6.

[0024] One end of the drive component 4 is hinged to the seat frame 2, and the other end is hinged to the middle part of the second leg plate connecting rod 6.

[0025] One end of the second leg plate connecting rod 6 is hinged to the seat plate frame 2, and the other end is hinged to one end of the first leg plate connecting rod 5; the other end of the first leg plate connecting rod 5 is hinged to the leg plate connecting frame 1.

[0026] The leg plate connecting frame 1 and the seat plate frame 2 are connected by a hinge.

[0027] The fan blade 3 is a 100° fan-shaped plate, and a limiting groove 7 is provided along the arc of the fan blade 3. A limiting post 8 is provided on the leg plate connecting frame 1, and the limiting post 8 is locked in the limiting groove 7. The center of the fan blade 3 is hinged to the hinge axis between the leg plate connecting frame 1 and the seat plate frame 2.

[0028] A limiting block is provided on the fan blade 3, and a limiting block matching the limiting block is provided on the seat frame 2 to prevent the fan blade 3 from being pulled out of the leg plate frame by external force.

[0029] The first leg plate connecting rod 5 is S-shaped, and the second leg plate connecting rod 6 is arc-shaped.

[0030] The driving component in this embodiment is a hydraulic cylinder.

[0031] like Figure 3 As shown, the limiting post 8 of the leg plate connecting frame 1 slides in the limiting groove 7 of the fan plate;

[0032] like Figure 4 As shown, when the leg plate connecting frame 1 bends upward, the limiting post 8 is located at the end of the limiting groove 7. At this time, the limiting post 8 drives the fan blade 3 to slide along with the leg plate connecting frame 1. The fan blade 3 can cover the gap at the angle between the leg plate connecting frame 1 and the seat plate frame 2 to prevent the operator's hand from being pinched.

[0033] like Figure 4-5 As shown, the drive shaft of the hydraulic cylinder extends forward to push the second leg plate connecting rod 6 to rotate clockwise, which in turn drives the first leg plate connecting rod 5 to move. This, in turn, causes the leg plate connecting frame to rotate clockwise around the hinge position between the leg plate connecting frame and the seat plate frame, achieving a 90° fold upward. The leg plate connecting frame then drives the fan blade to slide out through the limiting post, filling the gap between the leg plate connecting frame and the seat plate frame, thus providing a protective measure to prevent hand pinching. At the same time, a fan blade limiting block 10 is set on the fan blade, which cooperates with the seat plate limiting block 9 on the seat plate frame to achieve the effect that external force cannot pull the fan blade out of the leg plate frame.

[0034] like Figure 5 As shown, the drive shaft retracts to complete the opposite movement, achieving a 90° downward fold of the leg plate connecting frame.

[0035] In this embodiment, the driving component is a hydraulic cylinder, but it is not limited to hydraulic drive and can also be other driving methods, such as electric push rods.

[0036] This utility model adopts a planar two-link structure design, which can realize the leg plate bending up and down to 90°. At the same time, the link is a one-piece machined part, which has higher strength and greatly improves the load-bearing capacity of the leg plate.

[0037] This utility model relates to a connection structure between the leg plate connecting frame and the fan blade. Through the cooperation of the limiting groove and the limiting post, the fan blade is driven to cover the gap between the two as the leg plate folds up and down, protecting the operator and preventing their hands from being pinched.

[0038] The seat frame of this utility model can be a cavity between two frame plates for housing the driving component, connecting rod, fan blade, and leg plate connecting frame. Hinges are arranged along a line on the upper edge of the seat frame, with the hinge point to the leg plate connecting frame located at a corner of the seat frame. This hinge point also serves as the hinge for the fan blade. The hinge point of the fan blade is located at the center of the fan blade.

[0039] Example 2

[0040] An operating table is provided, which is equipped with the mechanism described in Example 1 for realizing the electric leg plate of the operating table bending up and down by 90°.

[0041] For any content not described in detail in this utility model, conventional technical knowledge in the field can be used.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
