[0029] See Figures 1 to 2 As shown, this utility model discloses a specific embodiment of a hand support, including: a connecting component 1, a supporting component 2, and a protective cover 3; the connecting component 1 is connected to the operating table; the supporting component 2 is connected to the connecting component 1; the protective cover 3 is connected to the supporting component 2, and a receiving cavity (not shown in the figure) is formed between the protective cover 3 and the supporting component 2; the protective cover 3 is provided with an opening communicating with the receiving cavity at one end near the connecting component 1 and at the other end away from the connecting component 1.

[0030] Specifically, connecting component 1, as a key connecting part, is responsible for firmly connecting the arm support to the operating table, ensuring a stable connection and laying a solid foundation for supporting the patient's limb. Support component 2, connected to connecting component 1, provides reliable support for the patient's limb, ensuring the limb remains in a proper position during surgery and reducing pain caused by uncomfortable limb placement. Protective cover 3, connected to support component 2, together with support component 2, forms a receiving cavity. This cavity has openings at both ends, one end close to connecting component 1 and the other end away. The opening design facilitates easy insertion of the patient's limb into the receiving cavity, while providing dedicated support and protective space to prevent unnecessary compression or impact to the limb.

[0031] In one specific embodiment, the support component 2 includes two support rods 21 and a flexible breathable layer 22; both support rods 21 are connected to the connecting component 1; both sides of the flexible breathable layer 22 are respectively connected to the two support rods 21; both sides of the protective cover 3 are also respectively connected to the two support rods 21; and a receiving cavity is formed between the protective cover 3 and the flexible breathable layer 22.

[0032] Specifically, the two support rods 21 are securely connected to the connecting component 1 to form a stable support platform. The flexible breathable layer 22 is connected to the two support rods 21 on both sides, and the protective cover 3 is also connected to the two support rods 21 on both sides, thus naturally forming a receiving cavity between the protective cover 3 and the flexible breathable layer 22. The flexible breathable layer 22 can conform to the curves of different patient limbs without adding extra burden to the patient's limbs, greatly improving the comfort of limb placement and providing good support. Furthermore, its breathability effectively prevents the limbs from becoming stuffy or sweaty due to prolonged placement, bringing a more comfortable experience to the patient. Preferably, the flexible breathable layer 22 is made of non-woven fabric.

[0033] In one specific embodiment, the protective cover 3 is slidably connected to two support rods 21 on both sides.

[0034] Specifically, the protective cover 3 is slidably connected to the two support rods 21 on both sides, allowing medical staff to slide the protective cover 3 on the support rods 21 according to the length of the patient's limb, thereby adjusting the position of the protective cover 3. This significantly improves the applicability of the arm support to different patients and ensures that each patient can obtain the best limb support and protection.

[0035] In one specific embodiment, the protective cover 3 includes a plurality of cover bodies 31 nested in sequence; the two sides of the cover body 31 are slidably connected to two support rods 21 respectively.

[0036] Specifically, through this nested sliding structure, the length of the protective cover 3 can be adjusted according to the length of the patient's limb, which can better meet the diverse needs of patients of various body types. Whether the patient's limbs are long or short, they can achieve a precise fit of the protective cover 3 with the help of this structure.

[0037] In one specific embodiment, the cover 31 is connected to a pulley (not shown in the figure), and the pulley is slidably connected to the support rod 21.

[0038] Specifically, to make the cover 31 slide more smoothly and stably on the support rod 21, the cover 31 is connected to a pulley, and the pulley and the support rod 21 slide together. The introduction of the pulley significantly reduces the friction when the protective cover 3 slides, making it easier and more convenient for medical staff to adjust the position of the protective cover 3, and improving the efficiency of the surgical preparation stage.

[0039] In one specific embodiment, the top of the support rod 21 is provided with a guide groove (not shown in the figure) arranged along the length direction of the support rod 21, and a number of pulleys are installed at the bottom of the cover 31 and slidably connected to the guide groove.

[0040] Specifically, the guide groove provides precise guidance for the sliding of the pulley, effectively preventing the pulley from deviating or shaking during the sliding process, ensuring the stability and reliability of the protective cover 3 throughout the adjustment process, and ensuring that the patient's limb is always in a safe and stable support environment.

[0041] In one specific embodiment, the cover 31 is made of a transparent material.

[0042] Specifically, during surgery, medical staff need to constantly monitor the patient's limb condition, from subtle changes in skin color and whether the limb is correctly positioned, to any abnormalities such as swelling or bleeding. By using a transparent cover 31, medical staff can directly and comprehensively observe the patient's limb condition without removing the protective cover 3. This avoids interference with limb support caused by frequent removal of the protective cover 3, reduces the risk of infection, ensures the continuous and stable progress of the surgery, and greatly improves the safety and efficiency of the surgical procedure.

[0043] In one specific embodiment, a flexible blood oxygen sensor 23 is connected to the side of the flexible breathable layer 22 near the protective cover 3.

[0044] Specifically, the flexible pulse oximeter 23 can monitor the patient's limb blood oxygenation in real time and accurately, and promptly feed the monitoring data back to medical staff. During surgery, blood oxygenation is one of the important parameters reflecting the patient's physical condition. By monitoring the patient's limb blood oxygenation in real time, medical staff can promptly detect any abnormalities that may occur, providing strong assurance for the safe conduct of the surgery and greatly improving the safety and reliability of the procedure.

[0045] In one specific embodiment, the two sides of the flexible breathable layer 22 are detachably connected to two support rods 21.

[0046] Specifically, this design greatly facilitates the cleaning and maintenance of the support frame. After surgery, the flexible breathable layer 22 can be easily removed from the support rod 21 for thorough cleaning and disinfection, ensuring the support frame remains hygienic and clean at all times, effectively preventing risks such as cross-infection, and providing a safety guarantee for subsequent surgeries. Understandably, the detachable connection between the flexible breathable layer 22 and the support rod 21 can use Velcro or snap-fit ​​connections, providing a stable connection and facilitating the installation and removal of the flexible breathable layer 22.

[0047] In one specific embodiment, at least one side of the flexible breathable layer 22 is also connected to a fixing strap 24.

[0048] Specifically, the main function of the fixation strap 24 is to stabilize the patient's limb after it has been placed on the support frame. During the surgery, the patient may unconsciously move their limb for various reasons. The fixation strap 24 effectively prevents this from happening, ensuring that the patient's limb remains in a proper position and avoiding interference with the surgical procedure due to limb movement, thus ensuring the smooth progress of the surgery.

[0049] More specifically, the fixation strap 24 can employ various methods such as Velcro, elastic bandages, and snap-on fixation straps 24, providing medical staff with more operational options. Velcro is easy to use, allowing medical staff to quickly fix and release the patient's limb, saving significant time in emergencies or when frequent limb position adjustments are required. Elastic bandages are also relatively easy to install and adjust, easily done with one hand, facilitating fine-tuning by medical staff during surgery based on the patient's condition. While snap-on fixation straps 24 are relatively complex to install, they offer high fixation strength. For surgeries with extremely strict limb fixation requirements, medical staff can use them to achieve precise and secure fixation, ensuring the smooth progress of the surgery and meeting the operational needs of medical staff in different surgical scenarios.

[0050] In one specific embodiment, the connecting component 1 is detachably connected to the operating table.

[0051] Specifically, this design allows the armrest to be easily and quickly installed on the operating table during use, and can also be easily disassembled for storage or transfer to other operating tables after surgery. Furthermore, when other operations or maintenance of the operating table are required, the detachable connecting component 1 will not obstruct the operating table in any way, thereby improving the flexibility and convenience of using both the operating table and the armrest.

[0052] In one specific embodiment, the connecting assembly 1 includes a fixing base 11 and a first clamping bolt 12; one end of the fixing base 11 is connected to the support rod 21, and the other end is provided with a slot (not shown in the figure); the first clamping bolt 12 is threadedly connected to the fixing base 11, and part of the first clamping bolt 12 extends into the slot.

[0053] Specifically, the first clamping bolt 12 is vertically positioned and extends into the slot from below the fixing seat 11. When installing the arm support, the edge of the operating table is inserted into the slot, and the first clamping bolt 12 is rotated so that it gradually penetrates deeper into the slot under the action of the thread, reducing the size of the slot and firmly clamping the fixing seat 11 to the edge of the operating table. This achieves a stable connection between the arm support and the operating table, ensuring that the arm support can withstand the weight of the patient's limb and various external forces that may occur during the operation without loosening or displacement.

[0054] In one specific embodiment, the support rod 21 is connected to the lifting assembly 4 and is connected to the fixed base 11 through the lifting assembly 4.

[0055] Specifically, the height of the support rod 21 can be easily adjusted via the lifting component 4. Different surgeries may require the patient's limbs to be in different height positions. The adjustability of the lifting component 4 allows the support frame to flexibly adjust the height of the support rod 21 according to the patient's body shape and surgical requirements, thereby better adapting to various surgical needs and helping to improve the patient's experience during surgery. At the same time, the lifting component 4 is connected to the fixed base 11, ensuring that the height of the support frame does not change arbitrarily during surgery. This avoids potential injuries to the patient's limbs caused by unstable support frame height, such as preventing sudden slippage of the limb or instrument collisions due to changes in support frame height, providing a safety guarantee for the smooth progress of the surgery.

[0056] In one specific embodiment, the lifting assembly 4 includes a fixing member 41 and a lifting member 42. The fixing member 41 is horizontally arranged, and its two ends are respectively connected to two support rods 21; the lifting member 42 is vertically arranged, and its two ends are respectively connected to the fixing member 41 and the fixing seat 11.

[0057] Specifically, the fixing member 41 is horizontally positioned and connected to two support rods 21 at each end, forming a transverse connection structure. This design allows the two support rods 21 to be interconnected and work together. When height adjustment is required, the fixing member 41 can evenly transmit the force applied by the lifting member 42 to the two support rods 21, ensuring that the two support rods 21 rise and fall synchronously and maintaining the overall balance of the support frame. The lifting member 42, based on the stable support provided by the fixed base 11, changes the height of the fixing member 41 through its own extension or transmission action, thereby driving the change in the height of the connected support rods 21 and the entire support frame.

[0058] More specifically, the lifting component 42 is a lifting rod, which is slidably connected to a groove (not shown in the figure) provided in the fixed base 11. The lifting assembly 4 also includes a second clamping bolt 43, which is horizontally arranged and threadedly connected to the fixed base 11. When the lifting rod maintains a constant height, the second clamping bolt 43 extends into the groove and abuts against the lifting rod, thereby clamping the lifting rod together with the fixed base 11. When it is necessary to adjust the height of the lifting rod, the second clamping bolt 43 is rotated to release the lifting rod, so that the lifting rod can slide up and down relative to the fixed base 11.

[0059] This design allows medical staff to easily lock and unlock the lifting rod height by simply rotating the second clamping bolt 43. This operation requires no complex tools or specialized skills, enabling rapid adjustment of the support frame height even in the stressful environment of a surgical procedure, saving preparation time. Furthermore, this clamping method effectively prevents the lifting rod from slipping due to the weight of the patient's limb, vibrations during surgery, or other external forces, ensuring the support frame maintains a stable height throughout the procedure. Even during prolonged surgeries, the support frame provides continuous and stable support to the patient's limb, reducing the risk of surgical interference caused by changes in support frame height and improving surgical safety and reliability. In addition, the sliding connection and simple bolt clamping structure used in this design are more cost-effective than some complex electric or hydraulic lifting systems. Its simple structure and relatively few parts not only reduce manufacturing costs but also make maintenance and upkeep easier. In case of malfunction, troubleshooting and repair are easier, reducing equipment downtime and improving equipment efficiency and economy, making it a cost-effective option for medical institutions.

[0060] It is understood that in other embodiments, the lifting component 42 may also employ a lifting motor, cylinder, or other similar solutions. By using a lifting motor, cylinder, or similar solutions, the lifting height of the lifting component 42 can be controlled more quickly, accurately, and stably, but the cost is higher.

[0061] In one specific embodiment, the ends of the first clamping bolt 12 and the second clamping bolt 43 are both connected to handles 5.

[0062] Specifically, the presence of handle 5 makes it easier for medical staff to operate the clamping bolts. During surgery, time is of the essence, and ease of operation is crucial. Handle 5 allows medical staff to quickly operate on the fixation or height adjustment of the support frame without the need for additional tools, saving surgical preparation time and improving work efficiency.

[0063] More specifically, the first clamping bolt 12 and the second clamping bolt 43 are hinged to the handle 5 so that the angle of the handle 5 can be changed according to the operating habits, which facilitates the operation of medical staff. After the operation is completed, the handle 5 can be rotated to a position close to other parts, reducing the space occupied by the protruding part and avoiding the risk of collision caused by the protruding handle 5, ensuring the safety of surrounding personnel and equipment during the operation. At the same time, it also makes the overall layout of the hand support frame more compact and reasonable.

[0064] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
