Description

Technical Field

[0001] This utility model relates to medical devices, and in particular to a hand support board for an operating table. Background Technology

[0002] When performing hand surgery on an existing operating table, a hand support board is usually inserted under the mattress. The hand support board extends to one side of the operating table, allowing the patient lying on the bed to place their hand so that the doctor can perform the surgery.

[0003] However, since this type of support board is not fixed to the operating table, it is not very stable. Moreover, when there are people on the operating table, it is very difficult to rotate the angle of the support board, which is not conducive to the angle movement during the operation to adapt to the changes of different surgical sites. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a surgical bed support board that solves at least one of the above problems.

[0005] An operating table armrest includes a table, a bed board, and an armrest. The bed board is disposed on the table, and the armrest is rotatably connected to the bottom of the bed board. The armrest is provided with a hand support, which is rotatably connected to the armrest, and a hand fixing component is provided on the hand support.

[0006] The armrest can rotate relative to the bed board on a horizontal plane;

[0007] The hand support can rotate relative to the hand support plate and be placed on top of the hand support plate, and the hand support can rotate relative to the hand support plate to one side of the hand support plate.

[0008] By fixing the hand support to the bottom of the bed board, the hand support becomes more stable and has a greater load-bearing capacity. Moreover, the hand support is rotatably connected to the bottom of the bed board. When in use, the hand support is rotated out from the bottom of the bed board, and when not in use, the hand support is rotated back to the bottom of the bed board, saving storage space, making it convenient to store and use, and at the same time, it will not affect the operation of any procedure other than the hand.

[0028] Please see Figure 1-8 An embodiment of the present invention provides a surgical bed support board 300, comprising a bed platform 100, a bed board 200, and a support board 300. The bed board 200 is disposed on the bed platform 100, and the support board 300 is rotatably connected to the bottom of the bed board 200. The support board 300 is provided with a hand support portion 400, which is rotatably connected to the support board 300, and a hand fixing member 600 is provided on the hand support portion 400.

[0029] The armrest 300 is rotatable relative to the bed board 200 on a horizontal plane;

[0030] The hand support 400 can rotate relative to the hand support plate 300 and be placed on top of the hand support plate 300, and the hand support 400 can rotate relative to the hand support plate 300 to one side of the hand support plate 300.

[0031] In this embodiment, by fixing the hand support 300 to the bottom of the bed board 200, the hand support 300 becomes more stable and has a greater load-bearing capacity. Moreover, the hand support 300 is rotatably connected to the bottom of the bed board 200. When in use, the hand support 300 can be rotated out from the bottom of the bed board 200, and when not in use, the hand support 300 can be rotated back to the bottom of the bed board 200, saving storage space, making it convenient to store and use, and at the same time not affecting the surgery other than the hand.

[0032] Since the hand support board 300 rotates from the bottom of the bed board 200, the top of the hand support board 300 will be lower than the top of the bed board 200, which can easily cause hand discomfort when supporting the hand. Therefore, by setting up the hand support part 400, the position of the hand support part 400 can be further increased so that the patient will not feel uncomfortable during the operation.

[0033] By setting a hand fixation device 600, the patient's hand will not shake during the operation, thus affecting the surgical outcome.

[0034] The components that support the rotation of the two structures can be a combination of a rotating shaft and a bearing. The specific configuration can be selected according to the actual situation.

[0035] In one embodiment, the support plate 300 includes a first support rod 320 and a second support rod 330. One end of the first support rod 320 is rotatably connected to the bottom of the bed board 200, and the other end of the first support rod 320 is rotatably connected to one end of the second support rod 330. The other end of the second support rod 330 is rotatably connected to the support part 400.

[0036] In this embodiment, by setting the hand support plate 300 as a two-way rotatable part, it can rotate similarly to the joints of the human hand, and rotate according to the placement of the hand when needed to correspond to the hand support position, making it more adaptable to different scenarios and making the patient more comfortable.

[0037] In one embodiment, the bottom of the bed board 200 is provided with an annular positioning post 210, and the top of the first support rod 320 is rotatably provided with a circular positioning rod 310. The annular positioning post 210 is hollow in the middle, and a plurality of vertically arranged positioning holes 220 are provided on the periphery of the annular positioning post 210. The periphery of the circular positioning rod 310 is provided with insertion holes corresponding to the positioning holes 220. The circular positioning rod 310 can be set in the annular positioning post 210, and the pin 500 passes through the positioning holes 220 and the insertion holes in sequence to achieve the purpose of positioning the circular positioning rod 310 in the annular positioning post 210.

[0038] In this embodiment, by setting the cooperation between the annular positioning post 210 and the circular positioning rod 310, the position of the circular positioning rod 310 can be adjusted by inserting and removing it into the annular positioning post 210, thereby achieving the purpose of adjusting the height of the hand support 300 to adapt to different people and different usage scenarios.

[0039] The positioning hole 220 and the insertion hole are aligned in the preset position so that the pin 500 can pass through and lock in sequence to fix the circular positioning rod 310.

[0040] The specific preset position can be set according to the actual position of the positioning hole 220 and the distance between the positioning holes 220.

[0041] In one embodiment, the positioning holes 220 are provided in at least three sets, the insertion holes are provided in two sets, and the pin 500 includes two sets of parallel insertion rods and a plate connecting the two sets of insertion rods.

[0042] In this embodiment, the positioning holes 220 are set into three groups and the insertion holes are set into two groups. Then there are two preset positions: the uppermost insertion hole is aligned with the uppermost positioning hole 220, and the uppermost insertion hole is aligned with the middle positioning hole 220. The two insertion rods on the pin 500 are aligned with the accurate positioning holes 220 and inserted into the insertion holes to achieve fixation.

[0043] The purpose of this design is to increase the number of insert rods, thereby increasing the load-bearing capacity of the 300-inch support plate. Furthermore, if all the insert rods are not aligned, they cannot be inserted into the sockets, thus preventing misinsertion and uncontrollable height.

[0044] In one embodiment, the bottom outer edge of the hand support 400 is provided with a lower protrusion, and the hand support plate 300 is provided with a notch corresponding to the lower protrusion. The lower protrusion is rotatably connected to the hand support plate 300 through the notch via a pivot.

[0045] When the hand support 400 rotates relative to the hand support plate 300 to one side of the hand support plate 300, and the tops of the hand support 400 and the hand support plate 300 are parallel, the lower protrusion abuts against the inner sidewall of the notch.

[0046] In this embodiment, by providing a lower protrusion, which is rotatably connected to the notch through cooperation with a pivot, when the handle part 400 is rotated to one side of the handle plate 300, and the tops of the handle part 400 and the handle plate 300 are parallel, the inner wall of the notch can become a limiting part 622, restricting the handle part 400 from continuing to rotate relative to the handle plate 300, maintaining the tops of the handle part 400 and the handle plate 300 parallel, which is convenient for storage.

[0047] In one embodiment, the hand support portion 400 includes a first hand support pad 410 and a second hand support pad 420, the lower protrusion is disposed on the outer edge of the bottom of the first hand support pad 410, and the second hand support pad 420 is rotatably connected to the side of the first hand support pad 410 opposite to the lower protrusion.

[0048] The axis of rotation of the second hand support pad 420 and the first hand support pad 410 relative to each other is vertical.

[0049] In this embodiment, by setting the hand support 400 into two parts, and the two parts being able to rotate relative to each other, it can rotate similarly to the joints of the human hand, and rotate according to the placement position of the hand when needed to correspond to the hand support position, making it more adaptable to different scenarios and making the patient more comfortable.

[0050] In one embodiment, the support arm 400 has connecting grooves on both sides, and the hand fixing member 600 is connected to the connecting grooves on both sides of the support arm 400 respectively. The hand fixing member 600 forms a forearm fixing space at the top of the support arm 400.

[0051] In this embodiment, by providing connecting grooves on both sides of the hand support 400, the hand fixing member 600 can be fixed in the connecting grooves and the hand is bound to the hand support 400.

[0052] In one embodiment, the hand fastener 600 includes two connecting straps, one end of which is connected to the connecting groove, and the other end of which is provided with Velcro.

[0053] In this embodiment, the connecting strap and the Velcro on the connecting strap facilitate the disassembly and fixation of the hand, and also make it easy to clean and replace.

[0054] In one embodiment, the hand fixing member 600 includes a fixing ring, which includes a first retaining ring 620 and a second retaining ring 610. The first retaining ring 620 and the second retaining ring 610 are rotatably connected to the connecting groove. The first retaining ring 620 is provided with a plurality of first toothed protrusions, and the second retaining ring 610 is provided with a plurality of second toothed protrusions that mesh with the first toothed protrusions. The first retaining ring 620 and the second retaining ring 610 achieve a fixing function by at least partial meshing.

[0055] In this embodiment, the hand fixing member 600 is set as a fixing ring, which is divided into a first retaining ring 620 and a second retaining ring 610 and is rotatably connected to the connecting groove. The retaining ring is provided with toothed protrusions. When the two toothed protrusions are engaged, the hand that is bound therein will be locked tighter when it struggles upward, making it difficult for the hand to break free.

[0056] To release the lock, simply press down the lower retaining ring and pull up and rotate the upper retaining ring.

[0057] In a preferred embodiment, the hand fixing member 600 includes three sets, two sets disposed on the first hand support pad 410 and one set disposed on the second hand support pad 420.

[0058] In this embodiment, two sets are placed on the first hand support pad 410 to better control the more flexible forearm, and one set is placed on the second hand support pad 420 to fix the upper arm.

[0059] In a preferred embodiment, the tops of the first armrest 410 and the second armrest 420 are flush with the top of the bed board 200.

[0060] In a preferred embodiment, the tops of the second hand support pad 420 and the first hand support pad 410 are angled outwards and upwards to increase the comfort of the patient's hands.

[0061] In one embodiment, the second toothed protrusion is disposed on a connecting plate 626, and a protective part 621 is provided at the end of the first retaining ring 620. The connecting plate 626 is rotatably disposed in the protective part 621. A hand-held part extending outward is provided on the side of the connecting plate 626. A through hole 625 is provided on the protective part 621 for the hand-held part to extend outward. The hand-held part can drive the connecting plate 626 to rotate counterclockwise, thereby realizing the separation of the first toothed protrusion and the second toothed protrusion.

[0062] In this embodiment, since the previous embodiment required pressing down on the lower retaining ring, which could easily cause injury to the hand, the second toothed protrusion is provided on the connecting plate 626. The connecting plate 626 is rotatably disposed in the protective part 621, which can not only prevent the connecting plate 626 and the toothed protrusion from being exposed, thus protecting the hand and the user, but also allow the hand to be released by operating the connecting plate 626 to separate the two toothed protrusions.

[0063] In one embodiment, the protective part 621 is provided with a spring-loaded part 700, which is used to make the connecting plate 626 have a downward rotational tendency, so that when fastening, the second retaining ring 610 can be rotated toward the protective part 621 and engaged so that the toothed protrusions on both can be engaged.

[0064] Specifically, the rebound section 700 is a V-shaped elastic steel plate, and the protective section 621 is provided with an installation section, in which the elastic steel plate is installed.

[0065] The mounting section includes a fixing part 624 located in the middle of the steel plate, a limiting part 622 at the top, and an abutting part 623 at the rear.

[0066] The springback part 700 is roughly positioned by the fixing part 624, the limiting part 622 and the abutting part 623.

[0067] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
