DETAILED DESCRIPTION

[0022] The features and exemplary embodiments of various aspects of the present disclosure will be described in detail below. In order to make the purposes, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present disclosure, rather than to limit the present disclosure. For those skilled in the art, the present disclosure can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present disclosure by illustrating examples of the present disclosure.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.

[0024] The applicant has discovered that, in traditional surgical settings, the patient's legs are typically supported and fixed by an assistant surgeon holding the legs with their hands. However, this method is unstable. Therefore, the applicant has proposed using a mechanical device, such as a leg support device, for fixation. However, existing leg support devices typically fix the legs in a fixed position or offer only very limited adjustment capabilities to accommodate the patient's posture, resulting in limited flexibility and inconvenience.

[0025] For this purpose, a leg support device is proposed, such as Figure 1As shown, the leg support device includes a fixing component 1, a support rod 2, an adjustment component 3 and a leg rest 4; the fixing component 1 is used to fix the leg support device to the target object; one end of the support rod 2 is detachably connected to the fixing component 1, and the other end is detachably connected to the adjustment component 3; the adjustment component 3 is used to connect the leg rest 4 to the support rod 2 in a fixed state, and allows the position of the leg rest 4 relative to the support rod 2 to be adjusted in an unlocked state. The patient's legs are fixed and supported by the support rod 2, the leg rest 4 and the fixing component 1, and the position of the legs can be changed by changing the position of the support rod 2. In addition, through the provision of the adjustment component 3, the leg rest 4 can be flexibly adjusted relative to the support rod 2, further improving the flexibility of adjusting the support state of the leg support device.

[0026] It is understood that in the operating room, the fixing assembly 1 generally fixes the leg support device to the side rails of the operating table to fix the patient's legs. The support rod 2 has a certain length and can extend the leg support 4 to a certain height to fit the patient's kneeling posture.

[0027] refer to Figure 1 and Figure 2 The adjustment assembly 3 connects the support rod 2 and the leg rest 4, increasing the flexibility of the leg rest 4 when supporting. When the adjustment assembly 3 is unlocked, the adjustment assembly 3 can move relative to the support rod 2 and rotate around the axis of the support rod 2, and the leg rest 4 can rotate relative to the adjustment assembly 3.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, the adjustment assembly 3 includes an inner sleeve 301, a first outer sleeve 302, a second outer sleeve 303 and a locking piece 304. The second outer sleeve 303 is fixedly connected to the leg support 4. The locking piece 304 is connected to the inner sleeve 301. The first outer sleeve 302 and the second outer sleeve 303 are fitted into the inner sleeve 301. The locking piece 304 moves axially relative to the inner sleeve 301 to axially lock the first outer sleeve 302 and the second outer sleeve 303.

[0029] Continue to refer Figure 3 and Figure 4, wherein the first end of the inner sleeve 301 is provided with a threaded hole 305, and the second end of the inner sleeve 301 is provided with a boss 306 protruding from the outer diameter of the sleeve. The threaded hole 305 is threadedly connected to the locking member 304. The inner diameter of the first outer sleeve 302 matches the outer diameter of the inner sleeve 301, and part of the inner diameter of the second outer sleeve 303 matches the outer diameter of the inner sleeve 301, and part of the inner diameter matches the outer diameter of the boss 306. The second outer sleeve 303 and the first outer sleeve 302 are sequentially inserted into the inner sleeve 301 from the end with the threaded hole 305 until the second outer sleeve 302 abuts against the boss 306. A circumferential positioning structure is provided between the first outer sleeve 302 and the inner sleeve 301. The circumferential positioning structure can be the anti-rotation plane 307 arranged along the axial direction of this embodiment. The anti-rotation plane 307 prevents the first outer sleeve 302 from rotating relative to the inner sleeve 301. A stop pin 308 is provided at one end of the threaded hole 305 of the inner sleeve to prevent the second outer sleeve 303 from being dislodged. A space between the stop pin 308 and the boss 306 allows a small range of axial movement between the first outer sleeve 302 and the second outer sleeve 303, so that the posture of the leg support 4 can be adjusted when the adjustment assembly 3 is unlocked.

[0030] The first outer sleeve 302 is provided with a first through hole 309, and the inner sleeve 301 is provided with a second through hole 310. The first through hole 309 and the second through hole 310 are positioned correspondingly and are used to receive the support rod 2. The first through hole 309 is a round hole matching the support rod 2, and the second through hole 310 is an elongated hole.

[0031] In actual use, after one end of the support rod 2 is passed through the first through hole 309 and the second through hole 310, the locking member 304 is rotated so that one end of the locking member 304 located in the threaded hole 305 abuts the support rod 2. As the locking member 304 rotates, it pulls the first outer sleeve 302 and the second outer sleeve 303 axially to fix them. The contact surfaces of the first outer sleeve 302 and the second outer sleeve 303 can be flat surfaces. Through the compression and friction of the flat surfaces, the first outer sleeve 302 and the second outer sleeve 303 are circumferentially fixed, that is, the leg rest 4 cannot rotate relative to the first outer sleeve 302. Furthermore, the locking surface 311 of the first through hole 309 and the locking member 304 fix the support rod 2, and the first outer sleeve 302 is fixed to the support rod 2. Therefore, the leg rest 4 is fixed relative to the support rod 2.

[0032] Of course, the length of the support rod 2 inserted into the first through hole 309 and the second through hole 310 can be adjusted according to actual needs, that is, it can be fixed at different positions on the support rod 2. Similarly, when the support posture of the leg rest 4 needs to be adjusted, it is only necessary to unlock the locking member 304. In the unlocked state, the leg rest 4 can be adjusted in multiple directions relative to the support rod 2.

[0033] In an optional embodiment, as Figure 3 As shown, in order to increase the stability of the circumferential fixation of the first outer sleeve 302 and the second outer sleeve 303, the adjacent surfaces of the first outer sleeve 302 and the second outer sleeve 303 are tooth surfaces 312 that can mesh with each other.

[0034] In an optional embodiment, the support rod 2 is a round rod with multiple bends, and the multiple bends are transitioned through arcs. Figure 5 As shown, the support rod 2 is a round rod with three bends. The bending design of the support rod 2 also brings a certain flexibility to the posture adjustment of the leg support device.

[0035] In an optional embodiment, the fixing assembly 1 is a side rail clamp that can lock the support rod 2. One end of the side rail clamp clamps the side rail, and the other end can fix the support rod. The support rod can rotate and move axially relative to the side rail clamp, and the support rod can be flexibly positioned. Figure 5 The following is an example of a side rail clamp solution. Of course, the side rail clamp solution is relatively mature and will not be described in detail here.

[0036] Although the present disclosure has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made based on the present application. Therefore, such modifications or improvements, which do not depart from the spirit of the present disclosure, are within the scope of protection claimed by the present disclosure.
