Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a lower limb support device for an operating table. Background Technology

[0002] In knee and ankle surgeries (such as replacement surgery, ligament repair, arthroscopic surgery, etc.), the stability of the patient's position is extremely important, and the operated limb needs to meet the requirements of multi-angle adjustment and dynamic locking during surgery. Therefore, the fixation and support of the patient's lower limb is extremely important during the operation.

[0003] Clinically, when a patient undergoes knee (or ankle) surgery, the patient's lower limb is usually first bent at a specific angle, and then supported and stabilized by medical staff. Alternatively, a pillow or other support may be placed on the inside of the knee joint before the medical staff provides further support and stabilization. Figure 6 (As shown). However, knee (or ankle) surgery generally takes a long time, and the bending angle of the patient's lower limb needs to be frequently changed during the operation, which poses a huge challenge to the physical strength of medical staff. In addition, some surgical instruments (such as bone hammers and chisels) apply a lot of force to the patient's lower limbs during the operation, and it is difficult to maintain the stability of the patient's lower limbs by simply relying on the manual support of medical staff, which leads to changes in the position and bending angle of the patient's lower limbs. This situation is not only detrimental to maintaining the precision of the surgical operation and increases the surgical risk, but may also lead to unsatisfactory postoperative recovery and seriously affect the patient's medical experience.

[0004] Therefore, there is a need for a lower limb support pad that can assist medical staff in providing stable support for the patient's lower limbs during surgery. Utility Model Content

[0055] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0056] This embodiment provides a lower limb support device for an operating table, such as... Figure 1-5 As shown, it includes: a base frame 1, a thigh support 2, a calf support 3, and a footrest 4; the base frame 1 is adapted to be fixedly installed on the operating table; one end of the thigh support 2 is rotatably connected to the base frame 1; one end of the calf support 3 is rotatably connected to the other end of the thigh support 2; the footrest 4 has a horizontally arranged foot pedal 41 and a connecting plate 42 disposed at one end of the foot pedal 41; the free end of the connecting plate 42 is rotatably connected to the other end of the calf support 3, and the side of the connecting plate 42 facing the free end of the foot pedal 41 is provided with an arc-shaped concave surface 420; the footrest 4 can move horizontally along the axial direction and is locked and fixed to the base frame 1 by a locking structure.

[0057] In this embodiment, when the footrest 4 is moved horizontally along the axial direction (lower limb extension direction), the angles of the thigh support 2 and the calf support 3 will change accordingly. In use, the base frame 1 is first fixedly installed in the designated position on the operating table to prevent movement during surgery. The required angles of the thigh support 2 and calf support 3 are determined according to the patient's specific condition and surgical needs. Then, the footrest 4 is moved to adjust the thigh support 2 and calf support 3 to the predetermined angles. Finally, the footrest 4 is locked to the base frame 1 using a locking structure. During surgery, the patient lies supine with their thighs and calves naturally aligned with the thigh support 2 and calf support 3, respectively, and their feet supported on the footrest 4. Medical staff hold the patient's thighs, calves, and ankles, and through the coordinated action of the thigh support 2, calf support 3, and footrest 4, the patient's lower limbs are fixed at a suitable angle.

[0058] The lower limb support device for the operating table in this embodiment is fixedly installed on the operating table via a base frame 1. The rotatable connection of the thigh support 2, lower leg support 3, and footrest 4, as well as the horizontal movement and locking of the footrest 4, achieves effective support and flexible adjustment of the lower limbs, thus adapting to different surgical positions. The horizontal setting of the footrest 4 improves foot stability. The arc-shaped concave surface 420 of the connecting plate 42 conforms to the heel contour, avoiding pressure on the patient's heel and improving patient tolerance. In this way, medical staff can not only reduce physical burden but also improve the efficiency and safety of surgical procedures, thereby providing better treatment results for patients.

[0059] The lower limb support device for the operating table in this embodiment, such as Figure 1 , Figure 2 As shown, the base frame 1 includes a first base frame 11, which includes a first mounting seat, a first mounting plate 114, a support rod 111, and a first locking nut 115. There are two first mounting seats, each including a first fixing seat 112 that can be fixedly mounted on the side rail 01 of the operating table and a first guide rod 113 that is vertically arranged on the top of the first fixing seat 112. The bottom of the first guide rod 113 is provided with external threads. The first mounting plate 114 is horizontally arranged, and its two ends are respectively mounted on the two first guide rods 113 through two first guide holes 1141. There are two support rods 111, which are vertically arranged opposite each other on the top of the first mounting plate 114, and their top ends are respectively rotatably connected to one end of the thigh frame 2. There are two first locking nuts 115, which are respectively screwed to the external threads at the bottom of the two first guide rods 113 to press the first mounting plate 114 onto the operating table.

[0060] In this embodiment, the first fixed seat 112 can be modified from existing mature products, such as existing operating table accessories that can slide and lock with the side rail 01. The support rod 111 can be fixedly connected to the first mounting plate 114 by welding, bonding or other methods. The first guide rod 113 can be fixedly connected to the first fixed seat 112 by welding, bonding or other methods. In use, the first fixed seat 112 is first fixed to the side rail 01. Then, the two ends of the first mounting plate 114 are respectively sleeved on the two first guide rods 113 through the two first guide holes 1141, and the two ends of the first mounting plate 114 are pressed together by the two first locking nuts 115.

[0061] In this embodiment, the support rod 111 and the first fixing seat 112 are vertically fixed to the side rail 01 of the operating table, which can form a stable mechanical support axis and avoid shaking during operation. The position of the first mounting plate 114 can be adjusted up and down to adapt to different mattress thicknesses. The first mounting plate 114 spans the bed surface, which can provide stable support and prevent lateral displacement. The first fixing seat 112 adopts a side rail clamping design, which can be quickly installed without damaging the structure of the operating table and is compatible with various brands of operating tables.

[0062] In this embodiment of the lower limb support device for the operating table, the support rod 111 further includes an upper rod 1111, a lower rod 1112, and a middle rod 1113; the top end of the upper rod 1111 is rotatably connected to the thigh frame 2; the bottom end of the lower rod 1112 is fixedly connected to the first fixed seat 112; and the two ends of the middle rod 1113 are telescopically connected to the bottom end of the upper rod 1111 and the top end of the lower rod 1112 respectively through a connecting structure.

[0063] In this embodiment, the segmented design of the support rod 111 allows for flexible adjustment of the height through the connection structure between the middle rod 1113 and the upper rod 1111 and the lower rod 1112, thus better adapting to the lower limb length and surgical needs of different patients, while also facilitating the replacement and maintenance of components.

[0064] In this embodiment of the operating table lower limb support device, the connecting structure includes a threaded hole or threaded shaft at the bottom end of the upper rod 1111, a threaded hole or threaded shaft at the top end of the lower rod 1112, and threaded shafts or threaded holes at both ends of the middle rod 1113.

[0065] In this embodiment, the threaded hole or threaded shaft at the bottom of the upper rod 1111, the threaded hole or threaded shaft at the top of the lower rod 1112, and the threaded shaft or threaded hole at both ends of the middle rod 1113 can be configured as follows: the middle rod 1113 can rotate independently, and clockwise rotation of the middle rod 1113 will bring the upper rod 1111 and the lower rod 1112 closer together; counterclockwise rotation of the middle rod 1113 will move the upper rod 1111 and the lower rod 1112 away from each other; or, clockwise rotation of the middle rod 1113 will move the upper rod 1111 and the lower rod 1112 away from each other; counterclockwise rotation of the middle rod 1113 will move the upper rod 1111 and the lower rod 1112 closer together. With this design, when the middle rod 1113 rotates independently, the upper rod 1111 and the lower rod 1112 can be moved closer or further apart, thereby achieving the purpose of adjusting the height of the support rod 111. The connection structure uses a threaded hole and a threaded shaft to securely connect the various parts of the support rod 111 together, while also facilitating height adjustment. The threaded connection provides self-locking friction to prevent the support rod from unexpectedly shrinking due to vibration during surgery. The threaded hole / shaft is a universal mechanical connection method, which facilitates the replacement and maintenance of parts.

[0066] The lower limb support device for the operating table in this embodiment, such as Figure 1 , Figure 2 As shown, the base frame 1 includes a second base frame 12, which includes a second mounting base, a second mounting plate 124, and a second locking nut 125. There are two second mounting bases, each including a second fixing base 123 that can be fixedly mounted on the operating table side rail 01 and a second guide rod 122 vertically positioned at the top of the second fixing base 123. The bottom of the second guide rod 122 has an external thread. The second mounting plate 124 is horizontally positioned, and its two ends are respectively mounted on the two second guide rods 122 via two second guide holes 1241. The second mounting plate 124 can be locked and fixed to the footrest 4 via a locking structure. There are two second locking nuts 125, which are respectively screwed to the external threads at the bottom of the two second guide rods 122 to press the second mounting plate 124 onto the operating table.

[0067] In this embodiment, the second fixing seat 123 can be modified based on existing mature products, such as existing operating table accessories that can slide and lock with the side rail 01, such as sliders, bearings, or fasteners. The second guide rod 122 can be fixed to the second fixing seat 123 by welding, bonding, or other methods. In use, the second fixing seat 123 is first fixed to the side rail 01, and then the two ends of the second mounting plate 124 are respectively sleeved onto the two second guide rods 122 through the two second guide holes 1241, and the two ends of the second mounting plate 124 are pressed together by the two second locking nuts 125.

[0068] In this embodiment, the position of the second mounting plate 124 can be adjusted up and down to accommodate different mattress thicknesses; the second mounting plate 124 spans the bed surface, providing stable support for the lower limbs and preventing lateral displacement; the second fixing seat 123 adopts a side rail clamping design, which can be quickly installed without damaging the operating table structure and is compatible with multiple brands of operating tables.

[0069] The lower limb support device for the operating table in this embodiment, such as Figure 2 , Figure 5 As shown, the locking structure includes a locking seat 121 and a buckle 43. The locking seat 121 is disposed on the top of the second mounting plate 124 and includes a frame 1210 and a plurality of horizontal bars 1211 arranged parallel to each other within the frame 1210. There is at least one buckle 43 disposed at the bottom of the foot pedal 41, and the buckle 43 can be engaged and fixed with the horizontal bars 1211.

[0071] In this embodiment of the operating table lower limb support device, the connecting plate 42 is provided with at least one buckle 43 on the side opposite to the free end of the foot pedal 41, and the free end of the foot pedal 41 is provided with a support structure 44.

[0072] Before or after surgery, patients often require procedures such as disinfection or bandaging. During this process, medical staff typically need to elevate the patient's lower limbs to facilitate the application of disinfectant or the wrapping of gauze (e.g., ...). Figure 7 (As shown). However, for larger patients, raising their lower limbs for an extended period of time requires a great deal of physical exertion and may even require the collaboration of multiple medical staff, resulting in the occupation and waste of manpower.

[0073] In this embodiment, as Figure 5As shown, the foot pedal 41 can be erected and fixed to the mounting base 121 by a buckle 43 on the side of the connecting plate 42 opposite to the free end of the foot pedal 41. The support structure 44 can support the patient's lower limbs and can be flat. When it is necessary to disinfect or wrap the patient's lower limbs with gauze, first move the foot pedal 41 to lower the height of the thigh support 2 and the calf support 3, then erect the foot pedal 41 and snap the buckle 43 on the side of the connecting plate 42 opposite to the free end of the foot pedal 41 onto the crossbar 1211, and then support the patient's lower limbs on the support structure 44. There can be multiple buckles 43 on the side of the connecting plate 42 opposite to the free end of the foot pedal 41, and they are distributed along the axial direction of the foot pedal 41, so that the angle of the foot pedal 41 after it is erected can be adjusted.

[0074] The lower limb support device for the operating table in this embodiment, further, such as Figure 1-3 As shown, the thigh support 2 includes a mounting frame 20, a first support plate 21, and a first support pad 22; one end of the mounting frame 20 is rotatably connected to the base frame 1, and the other end is rotatably connected to the lower leg support 3; the first support plate 21 is fixedly installed inside the mounting frame 20; the first support pad 22 is detachably installed on the upper surface of the first support plate 21.

[0075] In this embodiment, the mounting frame 20 can be a rectangular structure made of stainless steel or titanium alloy. The first support plate 21 can be made of metal and can be installed on the mounting frame 20 by welding, bolting, or other means. Guide holes can be provided on the first support plate 21, and a threaded shaft can be provided on the bottom surface of the first support pad 22, allowing it to be installed on the first support plate 21 by bolting. Alternatively, a plug adapted to the guide holes can be provided on the bottom surface of the first support pad 22, allowing it to be installed on the first support plate 21 by plugging it in. It can also be installed on the first support plate 21 by adhesive, magnetic attraction, or other means. The detachable design of the first support pad 22 facilitates postoperative cleaning and disinfection, avoiding cross-infection.

[0076] The lower limb support device for the operating table in this embodiment, further, such as Figure 1 , Figure 2 As shown, the lower leg support 3 includes a second support plate 31 and a second support pad 32; one end of the second support plate 31 is rotatably connected to the thigh support 2, and the other end is rotatably connected to the free end of the connecting plate 42; the second support pad 32 is detachably installed on the upper surface of the second support plate 31.
