[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0043] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] This embodiment provides a knee eversion position frame to address the issues of poor stability and convenience in existing technologies.

[0045] Example 1

[0046] like Figure 1As shown, this embodiment provides a knee eversion position frame, including a main frame 1, a footrest 2, and a binding strap 3. The main frame 1, as the main structure, mainly serves to support the footrest 2, while the binding strap 3 is used to bind the main frame 1 to the wearer's body, and the footrest 2 is used to support the patient's lower leg and ankle.

[0047] More specifically, the main frame 1 is secured to the wearer's chest, waist, or hips via straps 3. The footrest 2 is rotatably connected to the main frame 1 on the outside, away from the wearer.

[0048] With the above-mentioned technical solution, during surgical preparation, the surgeon can directly wear the main frame 1 on their body using the binding strap 3. The position of the main frame 1 can be adjusted vertically and positioned at the chest, waist, or hip according to the actual situation. During the operation, the patient's lower leg and ankle are first positioned on the foot support 2. This allows a single surgeon to complete the exploration, suturing, and repair of the posterior horn of the medial meniscus. Then, the rotation function of the foot support 2 and the vertical adjustment of the main frame 1 are used to precisely adjust the patient's lower leg flexion and eversion position and continuously stabilize the patient's position, thereby effectively solving the problems of poor stability and convenience of existing technologies.

[0049] In this embodiment, all the edges of the main frame 1 are rounded. By rounding the edges of the main frame 1, the possibility of the edges of the main frame 1 tearing the sterile surgical gown is reduced, the sterile surgical gown is prevented from being contaminated, and the safety of the surgical procedure is improved.

[0050] Furthermore, the bottom of the main frame 1 rests against the wearer's groin, which improves the stability of the fit.

[0051] Furthermore, the main frame 1 includes side panels 11 and a first soft pad 12. The side panels 11 serve as the skeleton of the main frame 1, while the first soft pad 12 conforms to the wearer's chest, hips, or waist. More specifically, the first soft pad 12 is attached to the inside of the side panels 11 via Velcro for easy replacement later. The first soft pad 12 conforms to the wearer's chest, hips, or waist. In this embodiment, the side panels 11 can be made of composite materials or metal, while the first soft pad 12 can be made of rubber, silicone, natural fiber, or other composite materials.

[0052] Through the above structural design, a first soft pad 12 is provided on the inner side of the side plate 11, which can prevent the side plate 11, which has a certain degree of hardness, from directly contacting the human body's torso, thereby improving the comfort of wearing this utility model.

[0053] Preferably, to facilitate adjustment of the tightness of the binding strap 3, the knee eversion position frame in this embodiment also includes a tightening adjustment component. This tightening adjustment component is similar to the shoulder strap buckle of a backpack shoulder strap, and it consists of a connecting piece and a square buckle. In this embodiment, the first end 31 of the binding strap 3 is fixedly connected to the outside of the side plate 11. The tightening adjustment component is disposed away from the first end 31 of the binding strap 3 and rotatably connected to the outside of the side plate 11. The second end 32 of the binding strap 3 passes through the loop end of the tightening adjustment component and is folded back towards the wearer. After the wearer binds the binding strap 3 to themselves, they pass the second end 32 of the binding strap 3 through the loop end of the tightening adjustment component and fold it back towards themselves to tighten it, which can adjust the tightness between the main frame 1 and the wearer.

[0054] Furthermore, the strap 3 is provided with Velcro 33, and the second end 32 of the strap 3 is attached to the strap 3 via Velcro 33. Velcro 33 is used to fix the second end 32 of the strap 3, so as to reduce the possibility of the strap 3 loosening due to the stretching force, thereby improving the reliability of the knee eversion position frame of this utility model.

[0055] Furthermore, there are two binding straps 3, one of which is located close to the footrest 2, and the other is located away from the footrest 2.

[0056] By setting two tie straps 3 spaced apart vertically, a "two-stage" binding is achieved. This method allows the first soft pad 12 to be firmly attached to the wearer's chest, hip, or waist, preventing the possibility of the knee eversion position frame of this utility model falling off the wearer and further improving the reliability of the knee eversion position frame of this utility model.

[0057] The implementation principle of this embodiment is as follows:

[0058] 1) During the surgical preparation phase, before washing hands and putting on gowns, the surgeon (wearer) wears the knee eversion positioning brace and secures it with strap 3. Then, the surgeon washes hands and puts on sterile gowns.

[0059] 2) During the surgery, the patient's feet are placed on footrest 2, and the knee joint is adjusted to an eversion position using the lateral support commonly used on the outside of the operating table. The surgeon can adjust the knee flexion angle by flexing and extending their body. If it is necessary to maintain the position for a long time, the surgeon can rise onto their toes, so that the anterolateral thigh root supports the lower edge of the side plate 11, providing sufficient upward support.

[0060] Example 2

[0061] like Figure 2As shown, based on Embodiment 1, this embodiment discloses a knee eversion position frame, which improves the footrest 2. Specifically, the footrest 2 in this embodiment includes a bracket 21 and a U-shaped footrest 22. One end of the bracket 21 is rotatably connected to the side plate 11, and the other end is fixedly connected to the outer wall of the U-shaped footrest 22.

[0062] In this embodiment, the bracket 21 is a steel component with excellent toughness and connection strength. The U-shaped footrest 22 is a thermoformed plastic component with a certain degree of elasticity and light weight.

[0063] By using the above technical solution, the bracket 21 is used to fix the U-shaped footrest 22, which avoids direct contact between the U-shaped footrest 22 and the side plate 11, reducing the possibility of wear and tear on the U-shaped footrest 22 during rotation. Simultaneously, relying on the steel component connection for support improves the supporting force of the U-shaped footrest. Furthermore, the U-shaped footrest conforms better to the outer contour of the patient's lower leg and ankle, facilitating the fixation of the patient's lower leg and ankle and improving the stability of this knee eversion position frame.

[0064] Furthermore, to improve patient comfort and reduce the likelihood of foot pressure sores, a second soft pad 23 is provided on the inner wall of the U-shaped footrest 22.

[0065] In this embodiment, the knee eversion position frame also includes a rotating connector 4 and a fastener 5.

[0066] The rotating end of the rotating connector 4 is set in a pre-cut slot in the side plate 11. The rotating end can rotate relative to the side plate 11 and cannot be pulled out of the slot. The rod of the rotating connector 4 extends from the inside of the side plate 11 to the outside of the side plate 11, and its fastening end is connected to the bracket 21.

[0067] By providing the rotating connector 4, the side plate 11 can be connected to the bracket 21, and the bracket 21 can rotate relative to the side plate 11.

[0068] Preferably, the rotating connector 4 can be a ball head screw, with the ball head end being the aforementioned rotating end, and the fastening end being the end away from the ball head end.

[0069] In this embodiment, in order to strengthen the connection between the bracket 21 and the U-shaped footrest 22 and prevent the U-shaped footrest 22 from falling off the bracket 21 during rotation, the bracket 21 is also U-shaped. The bracket 21 fits against the outer wall of the U-shaped footrest 22, and the middle and end of the bracket 21 are fixedly connected to the outer wall of the U-shaped footrest 22 by fasteners 5.

[0070] Example 3

[0071] like Figure 3 and Figure 4As shown, unlike Embodiment 2, the rotating connector 4 in this embodiment includes a rotating rod 41 and a fastening head 42.

[0072] The rounded end of the rotating rod 41 is positioned within a pre-cut slot in the side plate 11, while the rod body extends from the inside of the side plate 11 and passes through the end of the bracket 21. The end of the rotating rod 41 away from the rounded end is provided with an internal thread, while the fastening head 42 is provided with an external thread and is threadedly connected to the rotating rod 41.

[0073] Through the above structural design, the bracket 21 can be detachably connected to the side plate 11, making it easy to replace the U-shaped footrest 22 at any time.

[0074] Preferably, a rubber block can be provided outside the side plate 11 through which the rotating rod 41 protrudes. This rubber block is hollow and fits against the side plate 11 (but is not fixedly connected to the side plate 11), and the rotating rod 41 protrudes from the cavity of the rubber block. The rubber block and the fastening head 42 together clamp the bracket 21.

[0075] The above structural design improves the stability of the knee eversion position frame of this utility model, increases the friction of rotation, and requires the steering force to overcome the static friction of the rubber block in order to rotate, which is beneficial for the limiting of angle adjustment.

[0076] Example 4

[0077] like Figure 5 As shown, based on Embodiment 1, this embodiment adjusts the thickness of the side plate 11, bracket 21 and U-shaped foot support 22.

[0078] In this embodiment, the rotating connector 4 is a hinge or screw. One end of the rotating connector 4 penetrates the side plate 11 and is fixedly connected to the inner side of the side plate 11. The screw body of the rotating connector 4 penetrates the bracket 21 and the U-shaped footrest 22. The end of the rotating connector 4 away from the side plate 11 abuts against the inner wall of the U-shaped footrest 22. A gap is left between the screw body of the rotating connector 4 and the opening of the bracket 21 and the U-shaped footrest 22, so that the footrest 2 as a whole can rotate slightly relative to the side plate 11.

[0079] Preferably, to reduce the risk of breakage of the rotating connector 4, the bracket 21 is shaped like a "large soup spoon," with its rotatable connection to the side plate 11 at its "handle" end, i.e., the lower end. When the U-shaped footrest 22 supports the ankle, it presses down, while the rotating connector 4 acts as a lever, with its end away from the U-shaped footrest 22 tilting upwards, transferring the force to the side plate 11, and then to the surgeon, creating force feedback and facilitating easier adjustment of the patient's position during surgery.

[0080] Preferably, a gasket can be added between the end of the rotating connector 4 away from the side plate 11 and the inner wall of the U-shaped foot support 22.

[0081] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
