Technical Field

[0001] This utility model relates to the field of operating table technology, and in particular to an electric lumbar support mechanism for operating tables. Background Technology

[0002] The lumbar bridge mechanism in traditional operating tables is generally hydraulically driven, with transmission rods on both sides of the lumbar bridge. It has many shortcomings: (1) the overall structure is complex; (2) the transmission rods between the two sides of the lumbar bridge affect X-ray images during use. Utility Model Content

[0003] The purpose of this invention is to provide an electric lumbar support mechanism for operating tables that is simple in structure and easy to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an electric lumbar bridge mechanism for an operating table, comprising a bed frame and a table surface arranged on the bed frame, characterized in that a scissor lift structure is respectively provided on both sides of the bed frame, the scissor lift structure is driven by a motor, and the top of the scissor lift structure is connected to the table surface.

[0005] Further details: The scissor lift structure is a screw scissor lift structure, including a base frame, a scissor lift component mounted on the base frame, a top plate mounted on the top of the scissor lift component, a first connecting shaft for sliding on one side of the bottom of the scissor lift component, and a second connecting shaft mounted on the other side. The first connecting shaft is connected to one end of the base frame, and the second connecting shaft is connected to the other end of the base frame. The first connecting shaft has a threaded hole, and the second connecting shaft has a mounting hole. After the screw driven by the motor passes through the threaded hole and the mounting hole, it connects to the end limiting structure.

[0006] Further: A mounting plate is installed on the upper side of the tabletop, and the mounting plate and the top plate are connected by bolts.

[0007] Compared with the prior art, the present invention has the following advantages: the present invention has a simple and compact structure, is easy to use, and reduces the impact on X-ray images. Attached Figure Description

[0015] Example 1

[0016] See Figures 1 to 7 An electric lumbar bridge mechanism for an operating table includes a bed frame 11 and a table surface 12 arranged on the bed frame 11. Scissor lift structures are respectively provided on both sides of the bed frame 11. The scissor lift structures are driven by a motor, and the top of the scissor lift structure is connected to the table surface 12.

[0017] In this embodiment, the scissor lift structure is a screw-driven scissor lift structure. For example, the screw-driven scissor lift structure includes a base frame 21, a scissor lift component 22 mounted on the base frame 21, a top plate 27 on the top of the scissor lift component 22, a first connecting shaft 23 for sliding on one side of the bottom of the scissor lift component 22, and a second connecting shaft 24 on the other side. The first connecting shaft 23 is connected to one end of the base frame 21, and the second connecting shaft 24 is connected to the other end of the base frame 21. The first connecting shaft 23 has a threaded hole, and the second connecting shaft 24 has a mounting hole. A screw 25 driven by a motor 26 passes through the threaded hole and the mounting hole and connects to an end-limiting structure. The motor drives the screw to rotate, causing the scissor lift component to rise and fall. It should be noted that the screw-driven scissor lift structure can also refer to existing technologies; the above is merely an example and not a limitation.

[0018] In this embodiment, a mounting plate 31 is provided on the upper side of the platform 12, and the mounting plate 31 and the top plate 27 are connected by bolts. This design improves the stability after installation.

[0019] In this embodiment, there are two scissor lift structures: a first scissor lift structure 101 and a second scissor lift structure 102. Figure 7 This is a cross-sectional view of the first scissor lift mechanism.

[0020] Driven by the motor, the lead screw rotates, causing the scissor fork assembly to rise and fall. The lifting platform at the top of the scissor fork assembly allows the lumbar position of the operating table to be raised or lowered to facilitate surgery.

[0021] Example 2

[0022] The basic scheme is the same as in Embodiment 1. The difference is that, in order to facilitate the use of the mechanism, several slots are provided on the top of the top plate 27 along the width direction (the slots in the width direction run from one end to the other).

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above-described embodiments. All technical solutions that fall within the principles of this utility model are within its protection scope. For those skilled in the art, any improvements made without departing from the principles of this utility model should also be considered within its protection scope.
