Description

Technical Field

[0001] The present invention belongs to the technical field of surgical instruments, and particularly relates to a floating plate type memory surgical handrest board. Background Art

[0002] A surgical handrest board is arranged on an operating table to limit the patient's arm during the operation and prevent the unconscious arm movement of the patient from interfering with the surgical operation, which is an auxiliary instrument.

[0003] A common surgical handrest board is a whole board in a surgical bed with an automatically pop-up handrest frame disclosed in Publication (Announcement) No. CN119302820A, and supplemented with a strap structure in a surgical handrest frame disclosed in Publication (Announcement) No. CN221266316U to bind the patient's arm to the board. Therefore, during a long operation, the patient's arm will be fixed in one position for a long time, and the patient will feel numb and stiff in the arm after the operation, making the already weak patient after the operation more uncomfortable. In order to solve the problem that the existing surgical handrest board will cause the patient's arm to be numb and stiff during a long operation, the present application proposes a floating plate type memory surgical handrest board. Summary of the Invention

[0004] The purpose of the present invention is to provide a floating plate type memory surgical handrest board to solve the technical problem that the existing surgical handrest board will cause the patient's arm to be numb and stiff during a long operation.

[0005] To solve the above technical problem, the present invention provides a floating plate type memory surgical handrest board, including: a bottom plate, with an armpit limiting unit and a wrist limiting unit respectively arranged at both ends thereof, and a plurality of support arm units are penetrated in the bottom plate; a recording plate, which is installed below the bottom plate and penetrated with a plurality of recording units, and each recording unit is adapted to be pressed down after the corresponding support arm unit supports the corresponding part of the arm and descends; a recording locking unit, which is arranged on the recording plate and is adapted to lock each recording unit after the pressing is completed; a support arm locking unit, which is arranged on the bottom plate and is adapted to unlock each support arm unit after the current recording plate is removed and the next recording plate is installed, and lock each support arm unit after it falls onto the corresponding recording unit in the next recording plate, so as to switch the shape of the support surface formed by each support arm unit.

[0006] The beneficial effects of the present invention are as follows. By providing an armpit limiting unit and a wrist limiting unit at both ends of the bottom plate of the floating plate type memory surgical handrest, and arranging a plurality of support arm units in the bottom plate, the patient's arm can be limited within the corresponding area of the bottom plate and supported by the support arm units in the bottom plate. Each support arm unit can form a suitable shape of the support surface, which fits well with the arm. Therefore, it can be adapted to different surgical postures or patients with different body types. And because only the armpit and wrist are limited, the arm between the armpit and the wrist has the freedom of movement to switch the placement posture along with the change of the shape of the support surface formed by the support arm units. Before the operation, the patient can be asked to pose several placement postures of the arm. For each posed placement posture, it is recorded on a recording board by locking the recording unit through the recording locking unit. Then, another recording board is replaced, so as to record multiple placement postures. During the operation, first lock each support arm unit with the support arm locking unit, then remove the current recording board, install the next recording board, and then unlock each support arm unit with the support arm locking unit, so that each support arm unit falls onto the corresponding recording unit on this recording board, thereby switching the placement posture from the one corresponding to the previous recording board to the one corresponding to this recording board, enabling the patient's arm to switch between several placement postures that feel comfortable during the operation, and not easily accumulating a sense of stiffness and numbness.

[0020] Embodiment

[0021] As Figure 1As shown in the figure, the present invention provides a floating plate type memory surgical handrest, comprising: a bottom plate 100, with an armpit limiting unit 110 and a wrist limiting unit 120 respectively arranged at both ends thereof, and a plurality of support arm units 200 are arranged through the bottom plate 100; a recording plate 300, which is installed below the bottom plate 100 and is provided with a plurality of recording units 400, and each recording unit 400 is adapted to be pressed down after the corresponding support arm unit 200 supports the corresponding part of the arm and descends; a recording locking unit 500, which is arranged on the recording plate 300 and is adapted to lock each recording unit 400 after the pressing is completed; a support arm locking unit 600, which is arranged on the bottom plate 100 and is adapted to unlock each support arm unit 200 after the current recording plate 300 is removed and the next recording plate 300 is replaced, so that each support arm unit 200 falls onto the corresponding recording unit 400 in this recording plate 300 and then is locked, thereby switching the shape of the supporting surface formed by each support arm unit 200.

[0022] By arranging the armpit limiting unit 110 and the wrist limiting unit 120 at both ends of the bottom plate 100 and arranging a plurality of support arm units 200 in the bottom plate 100, this floating plate type memory surgical handrest can limit the patient's arm in the corresponding area of the bottom plate 100 and be supported by the support arm units 200 in the bottom plate 100. Each support arm unit 200 can form a suitable supporting surface shape and fit well with the arm, so that it can be adapted to different surgical positions or patients with different body types. And because only the armpit and the wrist are limited, the arm between the armpit and the wrist has the freedom of movement to switch the placement posture along with the change of the supporting surface shape formed by the support arm units 200. Before the operation, the patient can be made to pose several placement postures of the arm first. Each time a placement posture is posed, it is recorded on a recording plate 300 by locking the recording unit 400 through the recording locking unit 500. Then, another recording plate 300 is replaced, so as to record multiple placement postures. During the operation, first lock each support arm unit 200 with the support arm locking unit 600, then remove the current recording plate 300 and replace it with the next recording plate 300, and then unlock each support arm unit 200 with the support arm locking unit 600, so that each support arm unit 200 falls onto the corresponding recording unit 400 in this recording plate 300, thereby switching the placement posture from the one corresponding to the previous recording plate 300 to the one corresponding to this recording plate 300, so that the patient's arm can switch between several placement postures that feel comfortable during the operation and it is not easy to accumulate stiffness and numbness.

[0023] As Figure 1 and Figure 2 shown, it should be noted that Figure 2In the following figures, only three support arm units 200 and three recording units 400 are shown. A resilient floating plate 700 is provided below the base plate 100, and the resilient floating plate 700 is slidably connected to the base plate 100. A number of support arm springs 710 are provided on the resilient floating plate 700; as Figure 2 shown, the support arm unit 200 may include: a support plate 210, the bottom surface of which is connected to a support rod 220. The support rod 220 penetrates into the top surface of the base plate 100 and passes through the base plate 100 and the resilient floating plate 700. The resilient floating plate 700 is adapted to, when rising to the support arm height, enable each support arm spring 710 to penetrate into the bottom surface of the base plate 100, pass through the base plate 100, and abut against the corresponding support plate 210, so that the support plate 210 floats on the base plate 100. Thus, when the patient places the arm on each support plate 210, each support plate 210 forms a suitable shape of the supporting surface and fits well with the arm.

[0024] As Figure 2 shown, the recording unit 400 may include: a recording column 410, which penetrates into the top surface of the recording plate 300 and passes through the recording plate 300; a recording spring 420, which is provided on the recording plate 300 and abuts against the recording column 410, so that the recording column 410 floats on the recording plate 300. A recording plate fixed slide rail 130 is provided on one side wall of the base plate 100, and a recording plate rotating slide rail 140 is rotatably provided on the opposite side wall. It is adapted that after one end of the recording plate 300 is inserted into the recording plate fixed slide rail 130, the recording plate rotating slide rail 140 is turned down to cover the other end of the recording plate 300, so that the recording column 410 is located below the corresponding support rod 220 to be pressed down by the support rod 220 that follows the support plate 210 supporting the corresponding part of the arm and descends. Figure 2 And Figure 3 are schematic diagrams when the support plate 210 corresponds to different shapes of the supporting surface. By providing the recording plate fixed slide rail 130 and the recording plate rotating slide rail 140, the recording plate 300 can be quickly replaced. That is, when it is necessary to replace the recording plate 300 when recording the placement posture before the operation or switching the placement posture during the operation, as long as the recording plate rotating slide rail 140 is turned up, the current recording plate 300 can be taken out. Then, the next recording plate 300 is inserted, and turning down the recording plate rotating slide rail 140 to cover this recording plate 300 can complete the replacement. After the replacement, each recording column 410 is located below the corresponding support rod 220 to record the placement posture or switch the placement posture by docking with the descending support rod 220.

[0025] In at least one embodiment, the method of recording the placement posture is as follows. As Figure 3 shown, the recording columns 410 are arranged in columns on the recording plate 300; as Figure 4 shown, the recording locking unit 500 may include: a number of recording fixed clips 510, in combination with Figure 3 and Figure 2, all of which are provided on the bottom surface of the recording board 300, are respectively located on one side of a recording column 410, and are in contact with the recording column 410; Return to Figure 4 , a plurality of recording rotating clamping blocks 520, combined with Figure 5 , the upper ends of which are rotatably provided on the bottom surface of the recording board 300, and the recording rotating clamping blocks 520 are respectively located on the other side of a recording column 410; a plurality of recording locking rods 530, which are connected to the lower ends of a column of recording rotating clamping blocks 520 corresponding to each column of recording columns 410; a plurality of recording locking knobs 540, which are provided on one side of the recording board 300 and are connected to the corresponding recording locking rods 530, and are adapted to drive the corresponding recording locking rods 530 when rotating, referring to Figure 6 and Figure 7 , so that the corresponding recording rotating clamping block 520 turns towards the recording fixed clamping block 510 to clamp the pressed recording column 410. Before the operation, when the patient assumes a placement posture on each support plate 210, each support plate 210 compresses the support arm spring 710 and descends, and each support rod 220 also descends, thereby pressing down each recording column 410, that is, the placement posture corresponds to the height of each support plate 210 and the height of each recording column 410. At this time, by rotating the recording locking knob 540, the height of each recording column 410 corresponding to the placement posture can be recorded on the recording board 300. After that, by replacing the next recording board 300, the next placement posture can be recorded.

[0026] In at least one embodiment, the principle of the support arm locking unit 600 is the same as that of the recording locking unit 500. As Figure 3 shown, the support rods 220 are arranged in columns on the bottom plate 100; as Figure 4 and Figure 5 shown, the support arm locking unit 600 may include: a plurality of support arm fixed clamping blocks 610, all of which are provided on the bottom surface of the bottom plate 100, are respectively located on one side of a support rod 220, and are in contact with the support rod 220; a plurality of support arm rotating clamping blocks 620, the upper ends of which are rotatably provided on the bottom surface of the bottom plate 100, and the support arm rotating clamping blocks 620 are respectively located on the other side of a support rod 220; a plurality of support arm locking rods 630, which are connected to the lower ends of a column of support arm rotating clamping blocks 620 corresponding to each column of support rods 220; a plurality of support arm locking knobs 640, which are provided on one side of the bottom plate 100 and are connected to the corresponding support arm locking rods 630, and are adapted to drive the corresponding support arm locking rods 630 when rotating, so that the corresponding support arm rotating clamping block 620 turns towards the support arm fixed clamping block 610 to clamp the descending support rod 220.

[0027] As Figure 2As shown, a floating plate slide rail 150 is provided on the side wall of the bottom plate 100, and the floating plate slide rail 150 penetrates into the floating plate 700; a floating plate sliding locking member 720 is provided on the floating plate 700, so that when loading the recording plate 300 to record the shape of the supporting surface, it slides up to the height of the support arm and locks, and when replacing the recording plate 300 to switch the shape of the supporting surface, it unlocks and slides down from the height of the support arm. By setting the support arm locking unit 600, the floating plate slide rail 150, and the floating plate sliding locking member 720, when recording the placement posture before the operation, the floating plate 700 can be slid up to the height of the support arm and locked, referring to Figure 2 , in this way, the height of each recording post 410 corresponding to the placement posture is recorded on the recording plate 300 as described above. After replacing the next recording plate 300, the support arm spring 710 can keep each support plate 210 fully attached to the arm during the process of the patient changing from this placement posture to the next placement posture. When the placement posture is recorded, the patient can start the operation in the last recorded placement posture. When starting the operation, the floating plate 700 is unlocked through the floating plate sliding locking member 720, referring to Figure 8 , so that the support arm spring 710 descends into the bottom plate 100. At this time, each support rod 220 is supported by the recording post 410 clamped on the recording plate 300 corresponding to this placement posture. Of course, at this time, the support rod 220 can also be clamped in advance through the support arm locking unit 600, and the support plate 210 maintains the corresponding supporting surface shape. When it is necessary to switch the placement posture, first clamp each support rod 220 with the support arm locking unit 600, and then replace the recording plate 300 in the above-mentioned fast replacement method. For the replaced recording plate 300, only the most prominent recording post 410 on it needs to be in contact with the support rod 220. After that, unlock each support rod 220 with the support arm locking unit 600. Since there is no support arm spring 710 at this time, each support rod 220 falls onto the corresponding recording post 410 on this recording plate 300, thereby switching the placement posture from the one corresponding to the previous recording plate 300 to the one corresponding to this recording plate 300.

[0028] In order to enable the most prominent recording post 410 on the replaced recording plate 300 to be in contact with the support rod 220, as Figure 2 shown, a recording plate rotation slide rail locking member 141 is provided on the recording plate rotation slide rail 140 to lock with the bottom plate 100 after flipping down and covering the other end of the recording plate 300.

[0029] Furthermore, as Figure 2 shown, a recording plate locking member 310 is rotatably installed on the side surface of the recording plate 300.

[0030] As Figure 1As shown in the figure, both ends of the bottom plate 100 are respectively connected to the side cantilever brackets 160; the axilla limiting unit 110 includes: an axilla shelf 111, which is connected to one side cantilever bracket 160; an axilla strap 112, which is arranged on the axilla shelf 111; the wrist limiting unit 120 includes: a wrist shelf 121, which is connected to the other side cantilever bracket 160; a wrist strap 122, which is arranged on the axilla shelf 111. Through the side cantilever brackets 160, the axilla shelf 111 and the wrist shelf 121 can be adjusted, so that in the case of different surgical positions or patients with different body types, they can be adapted, and can be folded after the operation.

[0031] As Figure 9 shown in the figure, a surgical table cantilever bracket 170 is connected to one side wall of the bottom plate 100, and an infusion rod mounting slider 180 is arranged on the opposite side wall. By setting the surgical table cantilever bracket 170, after the bottom plate 100 is connected under the surgical table, it is very convenient to take out this floating plate type memory surgical handrest from under the surgical table, place it in a suitable position, and tuck this floating plate type memory surgical handrest back under the surgical table after the operation. By setting the infusion rod mounting slider 180, an infusion rod can be inserted, which is convenient for infusion.

[0032] In summary, this floating plate type memory surgical handrest is provided with an axilla limiting unit 110 and a wrist limiting unit 120 at both ends of the bottom plate 100, and a number of support arm units 200 are arranged in the bottom plate 100, so that the patient's arms can be limited in the corresponding areas of the bottom plate 100 and supported by the support arm units 200 in the bottom plate 100. Each support arm unit 200 can form a suitable support surface shape and fit well with the arms. Therefore, in the case of different surgical positions or patients with different body types, they can be adapted. And because only the axilla and the wrist are limited, the arms between the axilla and the wrist have the freedom of movement to switch the placement posture along with the change of the support surface shape formed by the support arm units 200. Before the operation, several placement postures of the arms can be let the patient pose first. For each posed placement posture, it is recorded on a recording board 300 by the way of locking the recording unit 400 through the recording locking unit 500. Then another recording board 300 is replaced, so as to record multiple placement postures. During the operation, first lock each support arm unit 200 with the support arm locking unit 600, then remove the current recording board 300, install the next recording board 300, and then unlock each support arm unit 200 with the support arm locking unit 600, so that each support arm unit 200 falls onto the corresponding recording unit 400 on this recording board 300, so as to switch the placement posture from the one corresponding to the previous recording board 300 to the one corresponding to this recording board 300, so that the patient's arms can switch between several placement postures that feel comfortable during the operation, and it is not easy to accumulate the feeling of stiffness and numbness.

[0033] In the embodiments provided in the present application, it should be understood that the disclosed systems and devices can be implemented in other ways. The embodiments described above are merely illustrative. For example, the division of the mechanisms is only a logical function division, and there may be other division methods in actual implementation. For another example, multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed.
