Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present utility model should have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure belongs. The "first", "second" and similar terms used in the present disclosure do not denote any order, quantity or importance, but are only used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left", "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0029] In the specific implementation manners provided by the present disclosure, a surgical position hand support device is provided. Refer to Figures 1 to 4As shown, the surgical position hand support device includes: a fixing frame 1, a support frame 2, and a locking member 3. Among them, the fixing frame 1 can be connected to the operating table. The support frame 2 has a support position for supporting the patient's arm. The support frame 2 is slidably connected to the fixing frame 1 through the locking member 3 in a lockable manner. That is, before the operation, medical staff should carefully evaluate the patient's body type, arm length, and joint range of motion and adjust the height of the support position appropriately according to the type of operation, so as to ensure that the patient's arm can be placed on the support position more naturally. The position of the support frame 2 is particularly important. That is, the position of the support position can allow the patient's arm to stretch naturally without excessive pulling or compression.

[0030] In the present disclosure, the height of the support frame 2 can be adjusted through the locking member 3. The height of the support position should be adjusted to a position where the patient's arm is relaxed and does not need to be lifted or drooped excessively. A good height can reduce the hanging pressure on the arm and keep the blood circulation smooth at the same time. Also, when actually using the hand support device, during the preoperative preparation process, after the height of the support frame 2 is adjusted, the patient can be asked to lie down and asked about their feelings to ensure there is no discomfort or compression. At the same time, medical staff can closely observe the patient's reaction and fine-tune the height of the support frame 2 as needed.

[0031] Through the above technical solution, during the preoperative preparation process, medical staff can evaluate the patient's body type and the type of operation to be carried out, and judge whether the position of the support frame 2 can make the patient's arm be placed on the support position in a natural state, thereby reducing the discomfort of the patient during the operation as much as possible. That is, medical staff can adjust the position height of the support frame 2 through the locking member 3, and ensure that the arms of different patients can be placed on the support position more naturally by adjusting the height, improving the versatility of the surgical position hand support device.

[0032] In some embodiments, the fixing frame 1 is constructed as an L-shaped metal rod, which can be formed by welding two metal rods with square cross-sections and the angle between the connecting parts of the two metal rods is 90°. Two plug plates are welded to one end of the L-shaped metal rod, that is, when the L-shaped metal rod is fixed on the operating bed, the bed board of the operating bed should be located between the two plug plates, and the L-shaped metal rod is connected to the operating bed by plugging. The support frame 2 includes a collar, a connecting sleeve, a set screw, a support rod and a placement plate. The connecting sleeve is welded to the collar and a threaded hole for threadedly connecting the set screw is provided on the connecting sleeve. The locking screw can pass through the threaded hole to pass through the connecting sleeve and extend to the inside of the ring. The ring is sleeved on one of the metal rods of the L-shaped metal rod (the metal rod facing away from the plug plate). A support rod is welded on the ring. The end of the support rod facing away from the ring is connected to a placement board. The placement board is used for placing the patient's arm. When the height of the placement board needs to be adjusted, the medical staff can loosen the locking screw to allow the ring sleeved on the L-shaped metal rod to slide. When the height position is appropriate, the locking screw can be tightened to fix the position of the placement board, so that the placement board can be suitable for more patients and provide good support for the patient's arm.

[0033] In some embodiments, reference Figures 1 to 3 As shown, the fixing frame 1 includes a fixedly connected pressing plate 101 and a connecting plate 102, and the supporting frame 2 includes a first plate 201 and a second plate 202 that are fixedly connected, and the supporting position is arranged on the upper surface of the second plate 202, wherein the pressing plate 101 is arranged between the bed body and the mattress of the operating bed, and the pressing plate 101 is pressed by the weight of the patient and the weight of the mattress of the operating bed, so that the pressing plate 101 and the connecting plate 102 fixedly connected to the pressing plate 101 are stably connected to the operating bed, and a locking member 3 is arranged on the side wall surface of the connecting plate 102 away from the pressing plate 101. In the present disclosure, the locking member 3 includes a screw 30 1 and a nut 302 threadedly connected to the screw rod 301, the screw rod 301 is fixedly connected to the connecting plate 102, the first plate 201 is provided with a through groove 2012 for the screw rod 301 to pass through, the first plate 201 is clamped between the connecting plate 102 and the nut 302, that is, when it is necessary to adjust the height of the support position, the medical staff can loosen the nut 302 to loosen the first plate 201, thereby realizing the mobility of the support frame 2, and after moving to a suitable height, the medical staff tightens the nut 302 to make the first plate 201 clamped and fixed by the nut 302 and the connecting plate 102.

[0034] In some embodiments, in order to make the support frame 2 more firmly connected to the fixing frame 1, refer to Figure 1 and Figure 2As shown, the number of the locking members 3 can be two. The two locking members 3 are oppositely arranged along the length direction of the connecting plate 102. By applying clamping forces to the first plate 201 from both ends of the connecting plate 102 simultaneously with the two locking members 3, the connection stability between the fixing frame 1 and the support frame 2 can be improved to a certain extent. Similarly, the number of the locking members 3 in the present disclosure includes but is not limited to two, and can also be multiple.

[0035] In some embodiments, when the patient's arm is placed in the support position, the patient's arm will apply a downward force to the support frame 2. Considering the connection stability and to avoid loosening of the connection between the support frame 2 and the fixing frame 1 during the operation, the locking member 3 includes a limiting block 303. Refer to Figures 1 to 3 , the limiting block 303 is fixedly connected between the connecting plate 102 and the screw 301. A receiving groove 2011 for the limiting block 303 to be inserted is provided on the first plate 201. The receiving groove 2011 communicates with the through groove 2012. The number of the receiving grooves 2011 is multiple, and the multiple receiving grooves 2011 are arranged at intervals along the length direction of the through groove 2012. That is, in order to ensure the connection stability between the fixing frame 1 and the support frame 2, when the height of the support frame 2 is adjusted, the limiting block 303 should be located in the receiving groove 2011. At this time, the limiting block 303 plays a supporting role. When the height of the support frame 2 needs to be adjusted, the medical staff can loosen the nut 302 and pull the first plate 201 towards the nut 302 to separate the limiting block 303 from the receiving groove 2011. At this time, the height of the support frame 2 can be adjusted. The medical staff can hold the first plate 201 and move the first plate 201 up and down. When the first plate 201 moves up and down, the through groove 2012 on the first plate 201 can serve as a passage for the screw 301 to pass through. After selecting the receiving groove 2011 at a suitable position, stop the up and down movement of the first plate 201, move the first plate 201 towards the connecting plate 102 to insert the limiting block 303 into the selected receiving groove 2011, and then tighten the nut 302, that is, the fixation between the fixing frame 1 and the support frame 2 is completed.

[0036] In some embodiments, in order to enable the surgical position hand support device to better adapt to most patients, provide good support for more patients as much as possible, and enable the patient's arm to be placed in the support position more naturally, the height adjustment of the support frame 2 should ensure that the support frame 2 can be adjusted in height more accurately. That is, multiple receiving grooves 2011 should be provided on the first plate 201. The multiple receiving grooves 2011 are arranged at equal intervals along the length direction of the through groove 2012. At the same time, the interval between two adjacent receiving grooves 2011 should be as small as possible so that the support frame 2 can be adjusted in height finely, thereby meeting the usage requirements of more patients and improving the versatility.

[0037] In some embodiments, in order to improve the connection strength between the fixing bracket 1 and the support bracket 2 and prevent the nut 302 from loosening during the operation, a rubber cushion block 304 may be provided. The rubber cushion block 304 is disposed on the end face of the limiting block 303 away from the connecting plate 102, and a part of the rubber cushion block 304 extends outside the receiving groove 2011. When the medical staff tightens the nut 302, the nut 302 first contacts the rubber cushion block 304 extending out of the receiving groove 2011 and then squeezes the rubber cushion block 304. The rubber cushion block 304 can effectively prevent the nut 302 from gradually loosening due to vibration. Through the frictional force provided by the rubber cushion block 304, the nut 302 can be effectively locked to prevent the nut 302 from automatically rotating and loosening.

[0038] In some embodiments, a through hole 3041 for the screw rod 301 to pass through is provided on the rubber cushion block 304. When installing the rubber cushion block 304, the rubber cushion block 304 is sleeved on the screw rod 301 through the through hole 3041, and then the rubber cushion block 304 can be pasted on the end face of the limiting block 303 away from the connecting plate 102 by means of glue.

[0039] In some embodiments, referring to Figure 2 and Figure 4 as shown, the rubber cushion block 304 can be fixed in a plug-in manner. That is, a plug-in post 3042 is provided on the end face of the rubber cushion block 304 close to the limiting block 303, and a plug-in groove 3031 for receiving the plug-in post 3042 is provided on the end face of the limiting block 303 away from the connecting plate 102. When installing the rubber cushion block 304, the plug-in post 3042 can be inserted into the plug-in groove 3031 by pressing, thereby completing the installation of the rubber cushion block 304. The plug-in post 3042 is made of rubber. When the plug-in post 3042 is inserted into the plug-in groove 3031, the plug-in post 3042 is in close contact with the inner cavity of the plug-in groove 3031, ensuring that the rubber cushion block 304 is firmly installed on the limiting block 303.

[0040] In some embodiments, referring to Figure 3As shown, in order to prevent the patient's arm from shaking or falling off the self-supporting position during the operation, perforations 2021 for tying and fixing with a tying strap can be provided on the second plate 202. Before the operation, the patient's arm can be tied and fixed with the tying strap. Among them, in order to more conveniently fix the tying strap on the second plate 202, the number of perforations 2021 can be multiple, that is, there are two groups of perforations 2021 arranged oppositely along the length direction of the second plate 202, and the number of each group of perforations 2021 is multiple and they are arranged at intervals along the length direction of the second plate 202. In this way, when medical staff need to fix the patient's arm with a tying strap, they can choose according to the actual situation, and can choose different combinations of perforations 2021 to fix the tying strap to ensure that the patient's arm can be well fixed.

[0041] In some embodiments, referring to Figure 3 As shown, in order to improve the comfort of the patient, a cushion layer 4 can also be provided on the upper surface of the second plate 202. Among them, the cushion layer 4 can be made of materials such as high-density foam, gel or medical-grade silicone, so as to provide sufficient support for the patient's arm and reduce the discomfort that may occur when the patient is fixed in one position for a long time.

[0042] Instructions for using the surgical position hand support device: First, insert the pressing plate 101 between the bed body and the mattress of the operating bed, so that the fixing frame 1 can be fixed by the weight of the patient and the weight of the mattress. Then, adjust the height of the support frame 2 installed on the fixing frame 1 to ensure that the support position can allow the patient's arm to be placed naturally, and provide good support for the patient as much as possible to reduce the discomfort of the patient. When the medical staff adjusts the height, loosen the nut 302 so that the nut 302 no longer clamps and fixes the first plate 201, and then displace the position of the first plate 201 until the receiving groove 2011 and the limiting block 303 are disengaged from each other. After disengagement, the first plate 201 can be moved up or down along the height direction of the connecting plate 102 according to actual needs. At this time, the corresponding receiving groove 2011 can be selected according to the actual situation of the required adjusted height. After the selection is completed, start to move the first plate 201. When moving, the through groove 2012 serves as a channel for the screw 301 to pass through. Until it is moved to the designated position, the medical staff moves the first plate 201 towards the connecting plate 102 so that the limiting block 303 is embedded in the corresponding receiving groove 2011, and then tighten the nut 302, which means the height position adjustment of the support frame 2 is completed. After the height adjustment is completed, the medical staff can pass the tying strap through the perforations 2021 on the second plate 202 to fix the patient's arm and prevent displacement due to surgical operations.

[0043] In addition, it should be noted that the material used for this surgical position hand support device needs to meet the requirements of light transmission and ray non-imaging for interventional surgery, and its material can be acrylic material.
