Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to a limb lifting device for limb surgery. Background Art

[0002] In actual clinical surgeries, such as knee joint replacement surgeries for orthopedic patients, comprehensive disinfection of the lower limbs is required before the operation, and it needs to be done twice. At present, medical staff need to hold the patient's ankles to lift the legs. Each leg lift needs to last for 5 to 10 minutes without being able to let go and rest in the middle, consuming a lot of physical strength and affecting the medical quality. Through a large number of clinical exchanges with medical staff and market research, leg lifting and disinfection is an indispensable process before the operation. However, the current manual leg lifting consumes a large amount of physical strength of medical staff, and there is an urgent need for a device to assist in leg lifting to replace manual leg lifting.

[0043] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0044] It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components during actual implementation. The type, quantity, and ratio of each component during actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0045] Embodiment 1

[0046] The applicant found that in the existing technology, the fixing method of the existing hook and the support rod is often complicated in structure, which not only increases the manufacturing cost of the equipment, but also makes medical staff spend more time and energy to familiarize themselves with and operate the equipment. Secondly, the problem of cumbersome operation further reduces the surgical efficiency. Especially in emergency situations where the position of the patient's limb needs to be quickly adjusted, such cumbersome operation may cause unnecessary delays. In addition, the lack of stability directly affects the safety and accuracy of the surgery.

[0047] In view of this, a support device is proposed. Please refer to Figure 1 , Figure 1 which is a partial schematic diagram of a support device provided in an embodiment of the present application. The support device includes: a support rod 2, a fixing piece 6, a third fixing block 5, and a connecting rod 7.

[0048] Among them, the support rod 2 has a hollow channel space for the third fixing block 5 to slide. The fixing piece 6 can be arranged outside the support rod 2. One end of the connecting rod 7 passes through the fixing piece 6 and is connected to the third fixing block 5 to prevent the third fixing block 5 from sliding inside the support rod 2.

[0049] The above content can connect the connecting rod 7 through the fixing piece 6 to the third fixing block 5 placed in the hollow channel space of the support rod 2. By rotating the connecting rod 7, the fixing piece 6 wraps around the support rod 2, completing the fixation of the third fixing block 5 inside the support rod 2 to prevent the third fixing block 5 from sliding.

[0050] In addition, to facilitate the passing of the connecting rod 7 through the fixing piece 6, a first opening 61 matching the connecting rod 7 is provided on the fixing piece 6. The fixing piece 6 can be in the shape of a groove and fit onto the outside of the support rod 2. The first opening 61 provided on the fixing piece 6 enables the fixing piece 6 to better cooperate with the support rod 2. The fixing piece 6 is in the shape of a groove and can fit more stably on the outside of the support rod 2, preventing the fixing piece 6 from moving on the support rod 2.

[0051] In addition, on the side of the support rod 2 where it fits the fixing piece 6, a second opening 23 is also provided. The second opening 23 can be a long strip-shaped opening to facilitate the passing of the connecting rod 7.

[0052] Reference Figure 3 , a first groove 51 is provided on the third fixing block 5. A small slider matching the opening of the support rod 2 can be provided below the third fixing block so that the third fixing block 5 can slide to a predetermined position within the support rod 2. Threads can also be provided in the first groove 51 for fixing the connection between the connecting rod 7 and the third fixing block 5, which can further enhance the stability of the connection.

[0053] The connecting rod 7 and the third fixing block 5 can be threadedly connected:

[0054] One end of the connecting rod 7 can be provided with an external thread, and an internal threaded hole matching the external thread is provided in the first groove 51 of the third fixing block 5. When it is necessary to connect the connecting rod 7 with the third fixing block 5, only the external threaded part of the connecting rod 7 needs to be screwed into the internal threaded hole of the third fixing block 5. Through the screwing action of the threads, the connecting rod 7 and the third fixing block 5 can achieve a firm connection.

[0055] Reference Figure 1 , the other end of the connecting rod 7 can be connected to a hook 21, and a sling 22 is connected to the hook 21. The sling 22 and the hook 21 can also be realized in various ways. For example, the hook 21 and the sling 22 can be threadedly connected or snap-connected to achieve a detachable effect. In Figure 1 , the hook 21 and the sling 22 are snap-connected. Specifically:

[0056] A snap mechanism can be provided on the sling 22. The snap mechanism includes a spring-loaded latch. When it is necessary to hang the sling 22 on the hook 21, the doctor only needs to press the latch forcefully. The latch will be recessed under the force and then pass through the hook 21. Release the latch, and the latch will automatically spring back to its original position due to the force of the spring. Similarly, the disassembly is also very convenient.

[0057] Reference Figure 4, sealing caps 24 can be provided at both ends of the support rod 2 to prevent foreign objects from entering the channel, which can effectively prevent foreign objects such as dust and particles from the outside from entering the channel space inside the support rod 2, thus avoiding obstacles or damage to the sliding components of the device caused by foreign objects.

[0058] The sealing cap 24 can be a cap made of elastic materials such as rubber and silica gel. These materials have good sealing performance and durability. In addition, the sealing cap 24 can also be fixed on the support rod 2 by means of threaded connection, snap connection, magnetic adsorption, etc. to ensure that it will not fall off easily during use. The sealing cap 24 can also take into account the need for easy disassembly and cleaning, thereby ensuring more convenient maintenance and servicing of the device.

[0059] Reference Figure 2 , it can also include a first support sling 31 and a second support sling 32. The first support sling 31 and the second support sling 32 are connected to the hanging ring 22. The first support sling 31 and the second support sling 32 as a whole present a parabola shape with the opening facing upwards. The distance between the two ends of the first support sling 31 and the second support sling 32 is adjustable. The parabolic shape of the first support sling 31 and the second support sling 32 provides better mechanical stability, making the limb not prone to shaking during the lifting process. In addition, the adjustable distance between the two ends increases the flexibility of the device, which can be adjusted according to the surgical needs, thereby improving the convenience of operation.

[0060] Embodiment 2

[0061] The embodiment of the present application also provides a limb surgery limb lifter system, including a limb surgery limb lifter and the support device in the above embodiment. The limb surgery limb lifter cooperates with the support device.

[0062] It should be noted that in actual clinical surgeries, such as knee joint replacement surgery for orthopedic patients, comprehensive disinfection of the lower limbs is required before the operation, and it needs to be done twice. At present, there are some limb lifting devices that can lift the lower limbs of surgical patients, but their lifting mechanisms are complex, taking up a lot of surgical space, lacking flexibility in actual use, and the support pads for lifting the patient's legs have a large contact area with the surgical patient. During the actual disinfection process, medical staff need to lift them to cooperate with the disinfection, which is very inconvenient in actual use. For this reason, such patients urgently need a more flexible and practical limb lifter during the operation. Therefore, the present invention provides a limb surgery limb lifter, including: a frame 1, a first upright post 11, a second upright post 12, a support rod 2, and a driving device 4.

[0063] Among them, the frame 1 includes a first column 11 and a second column 12. The first column 11 and the second column 12 are arranged in parallel. The support rod 2 is horizontally arranged and connected to the first column 11 and the second column 12. The driving device 4 is built into the first column 11. The driving device 4 may include a motor 45 and a lead screw 44 arranged at one end of the first column 11 away from the support rod 2. The lead screw 44 extends into one end of the first column 11 close to 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.

[0064] The above content can drive the first column 11 and the second column 12 to expand and contract through the driving device 4, so as to flexibly adjust the height of the support rod 2, realizing the automation of the lifting process, effectively reducing the physical burden of medical staff and improving the surgical efficiency. This limb lifter can adjust the height and width according to different usage needs, with higher flexibility in actual use and can adapt to the environments of various operating rooms.

[0065] Reference Figure 9 , the first column 11 is composed of 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 further includes a first fixing block 41 and a second fixing block 43. The first fixing block 41 is arranged at one end of the first upper column 111 close to the support rod 2, and the second fixing block 43 is arranged at one end of the first lower column 112 close to 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 same setting is also in the second column 12).

[0066] It is worth mentioning that the length of the first upper column 111 inserted into the first lower column 112 is preferably 0 - 150 cm, which is specifically determined according to the patient's condition.

[0067] Working principle: After starting the motor 45, the lead screw 44 is driven to rotate by the motor 45. A nut 42 is sleeved on the lead screw 44, and the nut 42 and the lead screw 44 are tightly fitted through threads. As the motor 45 continues to operate, the nut 42 smoothly moves up and down along the spiral track of the lead screw 44. At the top of the first upper column 111, a first fixing block 41 is fixedly arranged. The first fixing block 41 is internally provided with internal threads that cooperate with the lead screw 44. When the lead screw 44 rotates, through the threaded connection between the first fixing block 41 and one end of the lead screw 44, the first upper column 111 is effectively driven to slide longitudinally and smoothly relative to the first lower column 112.

[0068] Reference Figure 1 , the support rod 2 and the frame 1 can be made of metal or engineering plastics to provide greater support stability and avoid being too heavy and inconvenient to move. The frame 1 is movably arranged.

[0069] In addition, the flexibility and applicability of a limb surgery limb lifter are enhanced. The support device 3 may include a first support sling 31 and a second support sling 32. The first support sling 31 and the second support sling 32 are slidably connected to the support rod 2. The first support sling 31 and the second support sling 32 as a whole present a parabola shape with the opening facing upward. This design is not only beautiful, but more importantly, it can evenly disperse the supporting force and provide a more comfortable and stable supporting experience for the patient.

[0070] The distance between the first support sling 31 and the second support sling 32 can be flexibly adjusted according to the specific situation of the patient. This user-friendly design enables the lifter to adapt to patients with 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 slings, thereby providing more personalized surgical assistance and support for the patient.

[0071] Reference Figure 6 and Figure 7 In order to avoid secondary injury to the patient when the lower limb of the patient is placed on the first support sling 31 or the second support sling 32 due to the hardness of the sling, and to ensure that the lower limb can be fully and effectively disinfected before the surgery, a first liquid injection hose 311 is sleeved outside the first support sling 31, and a first infiltration flexible pad 312 is covered between the first support sling 31 and the first liquid injection hose 311. A second liquid injection hose 321 is sleeved outside the second support sling 32, and a second infiltration flexible pad 322 is covered between the second support sling 32 and the second liquid injection hose 321.

[0072] The first infiltration flexible pad 312 or the second infiltration flexible pad 322 can be high-elastic sponge or medical gauze. It has the function of storing liquid and can absorb the disinfectant in the lumen of the first support sling 31 and the second support sling 32 onto the infiltration flexible pad. Then, when the lower limb of the patient is placed on the infiltration flexible pad, it can be effectively disinfected. Moreover, on the one hand, the infiltration flexible pad can avoid mechanical damage to the skin of the patient's lower limb, and on the other hand, it can effectively increase the friction with the patient's lower limb to effectively lift the patient's lower limb.

[0073] To ensure more comprehensive and in-depth disinfection of the lower limbs before surgery, the first liquid injection hose 311 can be arranged along the extending direction of the first support sling 31, ensuring that the disinfection liquid can be evenly distributed along the entire length of the sling. A plurality of first through holes 3111 can be provided on the tube wall of the first liquid injection hose 311. The first through holes 3111 are communicated with the second through holes 3112 provided on the first support sling 31. The second through holes 3112 are arranged at intervals along the length direction of the first support sling 31. In this way, the disinfection liquid can penetrate into each part of the sling through multiple channels. The orifice of the second through hole 3112 points to the first wetting flexible pad 312, ensuring that the disinfection liquid can fully wet and cover the flexible pad, thereby further expanding the disinfection area and effect.

[0074] Similarly, the second liquid injection hose 321 can be arranged along the extending direction of the second support sling 32, ensuring that the disinfection liquid can be evenly distributed along the entire length of the sling. A plurality of third through holes 3211 can be provided on the tube wall of the second liquid injection hose 321. The third through holes 3211 are communicated with the fourth through holes 3212 provided on the second support sling 32. The fourth through holes 3212 are arranged at intervals along the length direction of the second support sling 32. In this way, the disinfection liquid can penetrate into each part of the sling through multiple channels. The orifice of the fourth through hole 3212 points to the second wetting flexible pad 322, ensuring that the disinfection liquid can fully wet and cover the flexible pad, thereby further expanding the disinfection area and effect.

[0075] In addition, the first liquid injection hose 311 can be a flexible silica gel tube, and the disinfection liquid can be injected through the first liquid injection hose 311 by a syringe. The disinfection liquid enters the lumen of the first support sling 31 through the first through holes 3111 and the second through holes 3112. Moreover, multiple groups of the second through holes 3112 are provided, and the multiple groups of the second through holes 3112 are preferably arranged at the middle section of the first support sling 31. When the patient's lower limb is placed on the first support sling 31, by squeezing the first support sling 31 to deform, the disinfection liquid in the first support sling 31 is squeezed through the second through holes 3112 to the first wetting flexible pad 312, so that the surface of the first wetting flexible pad 312 is wetted with the disinfection liquid to disinfect the contact position of the patient's lower limb. (The second liquid injection tube is the same as the first liquid injection hose 311 and will not be elaborated here.)

[0076] Reference Figure 1 For the convenience of fixing both ends of the first support sling 31, the support rod 2 is tubular. A third fixing block 5 is arranged inside the support rod 2. A second opening 23 is provided on the support rod 2. The hook 21 is installed on the third fixing block 5 through the second opening 23. A small slider matching 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.

[0077] It is worth mentioning that the hook 21 and the eye ring 22 can be purchased from the market, and no detailed description of the hook 21 and the eye ring 22 will be given here.

[0078] Reference Figure 5 , the frame 1 further includes:

[0079] A base 13, the lower ends of the first upright post 11 and the second upright post 12 are arranged on the base 13, and the base 13 is arranged in parallel with the support rod 2. Such a layout is not only beautiful and generous, but also ensures the stability of the limb lifter during use. A start switch 131 is also arranged on the side of the base 13 close to the first upright post 11, which is convenient for doctors to operate. Four wheels 132 can also be arranged under the base 13 for easy movement. When moved to a suitable position, a lock is arranged on the universal wheel to lock the rotation of the universal wheel and fix the whole limb lifter.

[0080] In addition, both the base 13 and the support rod 2 adopt a detachable connection method with the first upright post 11 and the second upright post 12. Such a design is not only convenient for users to assemble and disassemble, but also convenient for equipment maintenance and repair, greatly improving the practicability and durability of the limb lifter.

[0081] In order to reduce the possible harm to medical staff or patients during accidental collisions, we have adopted an arc-shaped design for the corners of the base 13 and both ends of the support rod 2. This design not only gives the device a higher roundness, making it more harmonious visually, but also improves the comfort of use. More importantly, the arc-shaped design effectively reduces friction and resistance, making the operation of the lifter smoother, thus further improving the efficiency and convenience of the operation.

[0082] In summary, when the four - limb surgical limb - lifting device is actually used, place the device at the head position of the operating table. Place the lower limbs of the patient to be operated on the first support sling 31 (the second support sling 32), and drive the lead screw 44 through the motor 45 to adjust the height of the support rod 2. Furthermore, the height of the first support sling 31 (the second support sling 32) can be adjusted, so as to lift the lower limbs of the patient to be operated on to match the limb position during the operation. A first infusion hose 311 (a second infusion hose 321) is arranged on the support sling. The first infusion hose 311 (the second infusion hose 321) is arranged along the extension direction of the first support sling 31 (the second support sling 32) and can soak the disinfectant on the surface of the first support sling 31 (the second support sling 32), which can effectively disinfect the contact position between the first support sling 31 (the second support sling 32) and the lower limbs, thus solving the problem of disinfection dead - ends existing in the existing limb - lifting devices. Moreover, this limb - lifting device can adjust the height and width according to different usage requirements, with higher practical flexibility, can adapt to the environments of various operating rooms, is convenient for disassembly and installation, and does not occupy too much space in the operating room.
