[0032] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0033] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0034] Example 1

[0035] The applicant has found that existing methods of fixing hooks and support rods in current technologies are often structurally complex. This not only increases the manufacturing cost of the equipment but also requires medical personnel to spend more time and effort to familiarize themselves with and operate it. Secondly, the cumbersome operation further reduces surgical efficiency, especially in emergency situations requiring rapid adjustment of the patient's limb position, where such cumbersome procedures may cause unnecessary delays. Furthermore, the lack of stability directly affects the safety and precision of the surgery.

[0036] In view of this, a support device is proposed, please refer to [link / reference]. Figure 1 , Figure 1 This is a partial schematic diagram of a support device provided in an embodiment of this application. The support device includes: a support rod 2, a fixing plate 6, a third fixing block 5, and a connecting rod 7.

[0037] The support rod 2 has a hollow channel space to accommodate the sliding of the third fixing block 5. The fixing plate 6 can be set outside the support rod 2. One end of the connecting rod 7 passes through the fixing plate 6 and connects to the third fixing block 5 to prevent the third fixing block 5 from sliding inside the support rod 2.

[0038] The above-mentioned components can be connected by the connecting rod 7 passing through the fixing plate 6 and connecting to the third fixing block 5 built into the hollow channel space of the support rod 2. By rotating the connecting rod 7, the fixing plate 6 can wrap around the support rod 2, thus fixing the third fixing block 5 inside the support rod 2 and preventing the third fixing block 5 from sliding.

[0039] In addition, in order to facilitate the connection rod 7 to pass through the fixing plate 6, the fixing plate 6 is also provided with a first opening 61 that cooperates with the connection rod 7. The fixing plate 6 can be in a groove shape to fit against the outside of the support rod 2. The first opening 61 on the fixing plate 6 allows the fixing plate 6 to better cooperate with the support rod 2. The groove shape of the fixing plate 6 can fit more stably against the outside of the support rod 2, preventing the fixing plate 6 from moving on the support rod 2.

[0040] In addition, a second opening 23 is provided on the side of the support rod 2 that is attached to the fixing piece 6. The second opening 23 can be a long strip opening to facilitate the passage of the connecting rod 7.

[0041] refer to Figure 3 The first groove 51 opened on the third fixing block 5 can be provided with a small slider that matches the opening of the support rod 2 below the third fixing block, so that the third fixing block 5 can slide to a predetermined position in the support rod 2. A thread can also be provided in the first groove 51 to fix the connection between the connecting rod 7 and the third fixing block 5, which can further enhance the stability of the connection.

[0042] The connecting rod 7 and the third fixing block 5 can be threaded together.

[0043] One end of the connecting rod 7 may be provided with an external thread, and the first groove 51 on the third fixing block 5 is provided with an internal thread hole that matches the external thread. When it is necessary to connect the connecting rod 7 and the third fixing block 5, simply screw the external thread part of the connecting rod 7 into the internal thread hole of the third fixing block 5. Through the screwing action of the thread, the connecting rod 7 and the third fixing block 5 can achieve a stable connection.

[0044] refer to Figure 1 The other end of the connecting rod 7 can be connected to the hook 21, and the hook 21 is connected to the lifting ring 22. The lifting ring 22 and the hook 21 can be connected in various ways; for example, the hook 21 and the lifting ring 22 can be connected by threads or snap-fit ​​to achieve a detachable connection. Figure 1 In the middle, the hook 21 and the ring 22 are connected by a snap-fit ​​connection, specifically:

[0045] The sling 22 can be equipped with a buckle mechanism, which includes a spring-loaded lock. When the sling 22 needs to be hung on the hook 21, the doctor only needs to press the lock firmly, and the lock will be indented under the force. Then, the lock passes through the hook 21 and is released. The lock will automatically spring back to its original position due to the force of the spring. Similarly, disassembly is also very convenient.

[0046] refer to Figure 4 Sealing caps 24 can be installed at both ends of the support rod 2 to prevent foreign objects from entering the channel. This can effectively prevent external dust, particles and other foreign objects from entering the channel space inside the support rod 2, thus avoiding obstruction or damage to the sliding parts of the device by foreign objects.

[0047] The sealing cover 24 can be made of elastic materials such as rubber and silicone, which have good sealing performance and durability. In addition, the sealing cover 24 can also be fixed to the support rod 2 by means of threaded connection, snap connection, magnetic adsorption, etc., to ensure that it will not easily fall off during use. The sealing cover 24 can also take into account the need for easy disassembly and cleaning, thereby ensuring that the maintenance and upkeep of the device is more convenient.

[0048] refer to Figure 2 It may also include a first support rope 31 and a second support rope 32, which are connected to the lifting ring 22. The first and second support ropes 31 and 32 are in the shape of an upward-opening parabola. The distance between the two ends of the first and second support ropes 31 and 32 is adjustable. The parabolic shape of the first and second support ropes 31 and 32 provides better mechanical stability, making the limb less prone to swaying during lifting. In addition, the adjustable distance between the two ends increases the flexibility of the device, which can be adjusted according to the needs of the surgery, thereby improving the convenience of operation.

[0049] Example 2

[0050] This application also provides a limb surgical lifting device system, including a limb surgical lifting device and a support device in the above embodiment, wherein the limb surgical lifting device cooperates with the support device.

[0051] It should be noted that in actual clinical surgery, such as knee replacement surgery for orthopedic patients, preoperative preparation requires comprehensive disinfection of the lower limbs, which must be performed twice. Currently, some limb-lifting devices can elevate the lower limbs of surgical patients, but their lifting mechanisms are complex, occupy a lot of surgical space, and lack flexibility in actual use. Furthermore, the support pad for elevating the patient's leg has a large contact surface with the surgical patient, requiring medical staff to lift the leg during disinfection, which is very inconvenient in actual use. Therefore, such patients urgently need a more flexible and practical limb-lifting device during surgery. In this regard, the present invention provides a limb-lifting device for limb surgery, including: a frame 1, a first column 11, a second column 12, a support rod 2, and a driving device 4.

[0052] The frame 1 includes a first column 11 and a second column 12, which are arranged in parallel. The support rod 2 is arranged horizontally and connected to the first column 11 and the second column 12. The drive device 4 is built into the first column 11. The drive device 4 may include a motor 45 and a lead screw 44 located at the end of the first column 11 away from the support rod 2. The lead screw 44 extends into the first column 11 near the end of the support rod 2. A nut 42 can be sleeved on the lead screw 44. The nut 42 cooperates with the lead screw 44 to complete the adjustment of the support rod 2.

[0053] The above-mentioned components can be driven by the drive device 4 to extend and retract the first column 11 and the second column 12, thereby flexibly adjusting the height of the support rod 2, realizing the automation of the lifting process, effectively reducing the physical burden on medical staff and improving surgical efficiency. The limb lifter can adjust its height and width according to different usage needs, making it more flexible in actual use and adaptable to various operating room environments.

[0054] refer to Figure 9 The first column 11 comprises a first upper column 111 and a first lower column 112. The lower end of the first upper column 111 is inserted into the upper end of the first lower column 112 and forms a sliding fit. The driving device 4 also includes a first fixing block 41 and a second fixing block 43. The first fixing block 41 is disposed at the end of the first upper column 111 near the support rod 2, and the second fixing block 43 is disposed at the end of the first lower column 112 near the motor 45. One end of the lead screw 44 is connected to the first fixing block 41, and the other end of the lead screw 44 is connected to the second fixing block 43. (The second column 12 has the same configuration).

[0055] It is worth mentioning that the length of the first upper column 111 inserted into the first lower column 112 is preferably 0-150cm, depending on the patient's condition.

[0056] Working principle: After the motor 45 is started, the motor 45 drives the lead screw 44 to start rotating. A nut 42 is sleeved on the lead screw 44. The nut 42 and the lead screw 44 are tightly engaged by threads. As the motor 45 continues to run, the nut 42 moves smoothly up and down along the spiral trajectory of the lead screw 44. At the top of the first upper column 111, a first fixing block 41 is fixedly installed. The first fixing block 41 has an internal thread that mates with the lead screw 44. When the lead screw 44 rotates, the first fixing block 41 is threadedly connected to one end of the lead screw 44, effectively driving the first upper column 111 to slide smoothly longitudinally relative to the first lower column 112.

[0057] refer to Figure 1 The support rod 2 and the frame 1 can be made of metal or engineering plastic to provide greater support stability and avoid excessive weight and inconvenience in moving. The frame 1 is a movable part.

[0058] In addition, the flexibility and applicability of the limb lifting device for limb surgery have been enhanced. The support device 3 may include a first support rope 31 and a second support rope 32. The first support rope 31 and the second support rope 32 are slidably connected to the support rod 2. The first support rope 31 and the second support rope 32 present an overall parabolic shape with the opening facing upward. This design is not only aesthetically pleasing, but more importantly, it can evenly distribute the support force, providing patients with a more comfortable and stable support experience.

[0059] The distance between the first support rope 31 and the second support rope 32 can be flexibly adjusted according to the specific situation of the individual patient. This humanized design allows the lift to adapt to patients of different body types and surgical needs, further improving the accuracy and safety of the surgery. Through simple adjustment operations, medical staff can easily adjust the distance between the ropes, thereby providing patients with more personalized surgical assistance support.

[0060] refer to Figure 6 and Figure 7 To avoid secondary injury to the patient when the lower limb is placed on the first support rope 31 or the second support rope 32 due to the rope being too stiff, and to ensure that the lower limb is adequately and effectively disinfected before surgery, the first support rope 31 is covered with a first injection tube 311, and a first impregnated flexible pad 312 is placed between the first support rope 31 and the first injection tube 311. The second support rope 32 is covered with a second injection tube 321, and a second impregnated flexible pad 322 is placed between the second support rope 32 and the second injection tube 321.

[0061] The first infiltrated flexible pad 312 or the second infiltrated flexible pad 322 can be a highly elastic sponge or medical gauze, which has the function of storing liquid. It can absorb the disinfectant in the lumen of the first support rope 31 and the second support rope 32 into the infiltrated flexible pad, so that when the patient's lower limbs are placed on the infiltrated flexible pad, they can be effectively disinfected. Moreover, the infiltrated flexible pad can avoid causing mechanical damage to the patient's lower limb skin, and can also effectively increase the friction with the patient's lower limbs, so as to effectively elevate the patient's lower limbs.

[0062] To ensure more comprehensive and thorough disinfection of the lower limbs before surgery, the first injection tube 311 can be arranged along the extension direction of the first support rope 31, ensuring that the disinfectant can be evenly distributed along the entire length of the rope. The tube wall of the first injection tube 311 can be provided with multiple first through holes 3111, which are connected to the second through holes 3112 provided in the first support rope 31. The second through holes 3112 are arranged at intervals along the length of the first support rope 31, so that the disinfectant can penetrate into various parts of the rope through multiple channels. The opening of the second through hole 3112 points towards the first soaking flexible pad 312, ensuring that the disinfectant can fully soak and cover the flexible pad, thereby further expanding the disinfection area and effect.

[0063] Similarly, the second injection hose 321 can be arranged along the extension direction of the second support rope 32 to ensure that the disinfectant can be evenly distributed along the entire length of the rope. The second injection hose 321 can be provided with multiple third through holes 3211. The third through holes 3211 are connected to the fourth through holes 3212 provided in the second support rope 32. The fourth through holes 3212 are arranged at intervals along the length of the second support rope 32, so that the disinfectant can penetrate into various parts of the rope through multiple channels. The opening of the fourth through hole 3212 points towards the second wetted flexible pad 322, ensuring that the disinfectant can fully wet and cover the flexible pad, thereby further expanding the disinfection area and effect.

[0064] In addition, the first injection tube 311 can be a flexible silicone tube, and disinfectant can be injected through the first injection tube 311 using a syringe. The disinfectant enters the lumen of the first support rope 31 through the first through hole 3111 and the second through hole 3112. Multiple sets of second through holes 3112 are provided, and these multiple sets of second through holes 3112 are located as close as possible to the middle of the first support rope 31. When the patient's lower limb is draped on the first support rope 31, the first support rope 31 is deformed by squeezing it, so that the disinfectant in the first support rope 31 is squeezed through the second through hole 3112 to the first soaking flexible pad 312, so that the surface of the first soaking flexible pad 312 is soaked with disinfectant to disinfect the contact area of ​​the patient's lower limb. (The second injection tube is the same as the first injection tube 311, and will not be described in detail here.)

[0065] refer to Figure 1 To facilitate the fixing of both ends of the first support rope 31, the support rod 2 is tubular, and a third fixing block 5 is provided inside the support rod 2. A second opening 23 is provided on the support rod 2, and the hook 21 is installed on the third fixing block 5 through the second opening 23. A small slider that cooperates with the second opening 23 is provided on the third fixing block 5. The small slider is located inside the support rod 2 and rolls along the length direction.

[0066] It is worth mentioning that the hook 21 and the ring 22 can be purchased on the market, and will not be described in detail here.

[0067] refer to Figure 5 Rack 1 also includes:

[0068] The lower ends of the first column 11 and the second column 12 are mounted on the base 13. The base 13 is parallel to the support rod 2. This layout is not only aesthetically pleasing but also ensures the stability of the limb lift during use. A start switch 131 is located on the side of the base 13 near the first column 11 for easy operation by doctors. Four wheels 132 are also installed under the base 13 for easy movement. Once moved to a suitable position, locking devices on the wheels prevent rotation, securing the entire limb lift in place.

[0069] In addition, the base 13 and the support rod 2 are detachably connected to the first column 11 and the second column 12. This design not only makes it easier for users to assemble and disassemble, but also makes it easier to maintain and care for the equipment, greatly improving the practicality and durability of the limb lifter.

[0070] To reduce potential injury to medical staff or patients in the event of accidental collisions, we have incorporated rounded corners on the base 13 and both ends of the support rod 2. This design not only gives the device a more rounded appearance, making it more visually harmonious, but also enhances user comfort. More importantly, the rounded design effectively reduces friction and resistance, making the operation of the lift smoother, thereby further improving the efficiency and convenience of the surgery.

[0071] In summary, when using this limb lifting device, it is placed at the head of the operating table. The patient's lower limb is placed on the first support rope 31 (second support rope 32). The height of the support rod 2 is adjusted by the motor 45 driving the lead screw 44, thereby raising the patient's lower limb to match the limb position during surgery. A first injection tube 311 (second injection tube 321) is installed on the support rope. The two injection tubes (321) are arranged along the extension direction of the first support rope 31 (second support rope 32) and can wet the surface of the first support rope 31 (second support rope 32) with disinfectant. This can effectively disinfect the contact area between the first support rope 31 (second support rope 32) and the lower limb, thereby solving the problem of disinfection dead corners in existing limb lifting devices. Moreover, the height and width of this limb lifting device can be adjusted according to different usage needs, making it more flexible in actual use. It can be adapted to various operating room environments, is easy to disassemble and install, and does not occupy too much operating room space.
