Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] Numerous different embodiments or examples are provided below to implement different structures of the present utility model. To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present utility model.

[0029] As Figure 1 shown, it is a schematic structural view of an adjustable armrest for an operating table provided by an embodiment of the present utility model. In Figure 1 the embodiment shown, the adjustable armrest for the operating table mainly includes the following several parts, namely:

[0030] Fixed rod 10, the fixed rod 10 includes a first end of the fixed rod;

[0031] Link rod 20, the link rod 20 includes an opposite first end of the link rod and a second end of the link rod. The first end of the link rod is fixedly connected to the first end of the fixed rod, and the link rod can rotate around the first end of the fixed rod;

[0032] Tie rod fixing device 30, the tie rod fixing device 30 is arranged in parallel with the link rod 20 and fixed on the link rod 20. The tie rod fixing device 30 is a telescopic structure that slides along the link rod 20;

[0033] Armrest mechanism 40, the armrest structure 40 is connected to the second end of the link rod and the tie rod fixing device.

[0034] The following Figure 1 will detail the structure and working principle of the adjustable armrest for the operating table provided by the present utility model. Please refer to Figure 1 , in Figure 1 the embodiment shown, the fixed rod 10 is generally a regular cuboid structure, including a first end and a second end arranged opposite to each other; wherein the first end of the fixed rod can be fixedly connected to other structures such as the link rod 20 and other structures. In Figure 1In it, a lower ratchet 01 and an upper ratchet 02 are further provided above the first end of the fixed rod. The lower ratchet 01 is fixedly welded to the first end of the fixed rod 10, and the upper ratchet 02 is arranged above the lower ratchet 01 and meshes with the lower ratchet 01. However, the upper ratchet 02 and the lower ratchet 01 can rotate relative to each other to separate the upper ratchet 02 and the lower ratchet 01. In the embodiment of the present utility model, the lower ratchet 01 is welded to the first end of the fixed rod 10, and the upper ratchet 02 is welded to the first end of the connecting rod 20. By clamping and meshing the upper ratchet 02 and the lower ratchet 01, the fixed rod 10 and the connecting rod 20 are fixedly connected together. Please refer to Figure 1 , in Figure 1 , the adjustable armrest of the operating bed further includes a fixing knob 03, and the fixing knob 03 is simultaneously clamped in the upper ratchet 02 and the lower ratchet 01 to fasten the fixed rod 10 and the connecting rod 20. Specifically, when the upper ratchet 02 and the lower ratchet 01 are meshed, the fixed rod 10 and the connecting rod 20 can be connected. However, relying only on the meshing of the upper ratchet 02 and the lower ratchet 01 cannot control the stable connection of the fixed rod 10 and the connecting rod 20. Therefore, a fixing knob 03 is further added. The fixing knob can be tightened to fasten the upper ratchet 02 and the lower ratchet 01, so as to fasten the fixed rod 10 and the connecting rod 20. When the fixing knob 03 is loosened, the connecting rod 20 can be controlled to rotate around the upper ratchet 02, thereby adjusting the position of the connecting rod 20 to realize the position adjustment of the armrest mechanism 40.

[0035] As Figure 2 shown, it is a top view of the adjustable armrest of the operating bed provided by the embodiment of the present utility model; the following will combine Figure 1 and Figure 2 to describe the tie rod fixing device and the armrest mechanism in detail. The tie rod fixing device 30 provided by the embodiment of the present utility model includes a toothed tie rod 04, a tie rod fixing block 05, a compression spring 06, a compression spring fixing block 07 and a toothed fixing block 08 which are connected in sequence. The toothed tie rod 04 further includes a toothed tie rod head, a toothed tie rod body and teeth 09. The teeth 09 are clamped in the armrest mechanism 40, and the toothed tie rod body sequentially passes through the tie rod fixing block 05, the compression spring 06, the compression spring fixing block 07 and the toothed fixing block 08. Please refer to Figure 1 and Figure 2, in this embodiment, the pull rod fixing block 05 and the gear shaping fixing block 08 are fixedly connected to the connecting rod 20, and their positions are fixed and unchanged at the same time; however, the position of the compression spring fixing block 07 will change with the expansion and contraction of the compression spring 06. Specifically, the gear shaping pull rod head can receive an external force to drive the gear shaping pull rod body and the gear shaping to move, thereby driving the compression spring 06 to expand and contract. At the same time, the expanding and contracting compression spring 06 will drive the compression spring fixing block 07 to move as well. The gear shaping 09 will also move, but due to the existence of the gear shaping fixing block 08, the position of the gear shaping 09 will be restricted to prevent the moving position of the gear shaping 09 from exceeding the position of the gear shaping fixing block 08; that is, the gear shaping fixing block 08 in the embodiment of the present invention mainly functions to limit the gear shaping 09. Similarly, the pull rod fixing block 05 limits the compression spring 06 and the gear shaping pull rod body at the same time to prevent the moving positions of the compression spring 06 and the gear shaping pull rod body from exceeding the range.

[0036] In the embodiment of the present invention, the arm protection mechanism 40 mainly includes several structures such as an arm protection baffle fixing block 010, an arm protection baffle rotating shaft sleeve 011, an arm protection baffle 012, and an arm protection baffle support frame 013. Specifically, as Figure 1 and Figure 2 shown, the arm protection baffle fixing block 010 is fixedly connected to the second end of the connecting rod. The arm protection baffle fixing block 010 can be a circular structure or other structures, and is mainly used to connect other structures such as the arm protection baffle rotating shaft sleeve 011, the arm protection baffle 012, and the arm protection baffle support frame 013. In the embodiment of the present invention, the arm protection baffle fixing block 010 can include an arm protection baffle fixing block body and a rotating ratchet. The arm protection baffle fixing block, the connecting rod 20, and the upper ratchet 02 are welded into an integral structure, mainly the arm protection baffle fixing block body, the connecting rod 20, and the upper ratchet 02 are welded into an integral structure. The rotating ratchet is arranged on the baffle fixing block, and the rotating ratchet can be clamped with the gear shaping. When the two are clamped, other structures arranged on the rotating ratchet cannot rotate anymore.

[0037] In the above embodiments, the rotating shaft sleeve of the arm guard baffle is fixed on the fixed block of the arm guard baffle, mainly on the rotating ratchet of the fixed block of the arm guard baffle. In this way, when the rotating ratchet rotates, it can drive the rotating shaft sleeve of the arm guard baffle to rotate as well. Similarly, the support frame of the arm guard baffle is fixed on the rotating shaft sleeve of the arm guard baffle. When the rotating shaft sleeve of the arm guard baffle rotates, it can drive the support frame of the arm guard baffle to rotate. The arm guard baffle 012 is connected to the side of the rotating shaft sleeve of the arm guard baffle; the arm guard baffle 012 can rotate around the side of the rotating shaft sleeve of the arm guard baffle to change the position of the arm guard baffle 012 and place the patient's arm. In the present utility model, the arm guard baffle may include an independent first baffle and a second baffle. The sides of the first baffle and the second baffle are both fixedly connected to the side of the support frame of the arm guard baffle, and the first baffle and the second baffle can rotate around the side of the support frame of the arm guard baffle to form an arm receiving space for receiving the patient's arm. At the same time, since the rotating ratchet can rotate, it can drive the rotating shaft sleeve of the arm guard baffle to rotate, and the rotating shaft sleeve of the arm guard baffle can drive the support frame of the arm guard baffle to rotate; when controlling the rotation of the rotating ratchet, it can ultimately drive the rotation of the arm guard baffle to change the position of the arm receiving space. And because the arm guard baffle itself can also rotate around the side of the support frame of the arm guard baffle, the arm guard baffle itself can further change the size of the arm receiving space by rotation.

[0038] In some other embodiments, a damping piece can be added between the brace support frame of the arm guard baffle and the fixed block of the arm guard baffle to adjust the stability of the arm guard baffle and the magnitude of the force required during rotation, so as to meet the needs of different users. In the usage scenario of the adjustable arm guard of the operating table provided by the present utility model, the fixing button 03 can be rotated to loosen the upper ratchet and the lower ratchet, and the connecting rod can be controlled to rotate around the upper ratchet according to actual needs to change the positions of the connecting rod and the arm guard mechanism. After determining the position, the fixing knob 03 is tightened to fasten the upper ratchet and the lower ratchet to prevent the connecting rod and the arm guard mechanism from moving again. When it is necessary to adjust the position of the arm guard mechanism, the insertion tooth pull rod head of the insertion tooth pull rod can be pulled to drive the insertion tooth 09 clamped with the rotating ratchet to separate from the rotating ratchet and move along the direction close to the insertion tooth pull rod head. At this time, since the insertion tooth 09 is disengaged from the rotating ratchet, the rotating ratchet can rotate, and then drive the rotating shaft sleeve of the arm guard baffle to rotate, and then drive the brace support frame of the arm guard baffle to rotate. After the brace support frame of the arm guard baffle rotates to a determined position, the insertion tooth pull rod head can be released, and the originally compressed compression spring 06 will push the entire insertion tooth pull rod to move towards the rotating ratchet, so that the insertion tooth and the rotating ratchet are clamped again. At this time, the rotating ratchet will be clamped and unable to rotate, thus fixing the position of the brace support frame of the arm guard baffle. The operation process of the whole operation is simple. By controlling the fixing knob 03 and the insertion tooth pull rod, the arm guard mechanism can be rotated at any angle; and since the positions of the insertion tooth pull rod and the fixing knob are relatively close, only one person is required to operate, and the operation is simple and labor-saving. At the same time, the maximum adjustable range of the insertion tooth pull rod in the present utility model is 450 mm, and the adjustable range is also relatively large, with strong practicability.

[0039] The present utility model also provides an operating table, which includes the adjustable arm guard of the operating table as described in any one of the above, and further includes a clamp and an operating table body; wherein, the operating table body is the main bearing structure for the patient, and the patient can lie on the operating table body. The adjustable arm guard of the operating table described in the foregoing embodiments can be fixed on the side rail of the operating table body through the clamp and is then used to bear the patient's arm. When the adjustable arm guard of the operating table is not needed, it can be removed, which will not occupy the space of the operating table body and will not block the space for other operations of the user. At the same time, the size of the arm guard mechanism in the adjustable arm guard of the operating table provided by the present utility model can be set according to actual needs to be applicable to users of different body types, with a wide range of applications.

[0040] In the above embodiments, the descriptions of each embodiment have their own focuses. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
