Description

Technical Field

[0001] The utility model relates to the field of medical appliances, in particular to a leg support device with adjustable leg support angle used in unicompartmental replacement surgery. Background Art

[0002] Unicompartmental knee replacement is also called partial knee replacement because osteoarthritis patients have more single-compartment wear and tear, only a part of it is worn out, and the other part is intact. At this time, there is no need to perform a large total knee prosthesis replacement. A small, cartilage-pad-like structure can be used for partial replacement to solve the problem. In the prior art, when suturing the lower limbs in clinical orthopedic surgery, the lower limbs are generally lifted by a surgical assistant and another surgeon sutures the limbs. Manual leg lifting is a laborious task, and it is not easy to maintain stability when lifting, which affects the effect of the operation. In order to reduce the labor intensity of medical staff and improve the quality of surgery, a lower limb bracket is generally used for support at this stage. However, the connection between the support plate and the support rod of the existing lower support bracket is simple, and the angle of the support plate cannot be adjusted at will. Moreover, it is still unstable to support with only one support rod, and the reliability is poor. Utility Model Content

[0005] Furthermore, the two lower ends of the support rods are fixedly connected with support blocks, and the front side surface and the rear side surface of the support block are arc surfaces.

[0006] Furthermore, a buffer pad 1 is provided on the upper side of the arc-shaped support plate, and a buffer pad 2 is provided on the lower side of the support block.

[0007] The advantages of the utility model compared with the prior art are: the utility model adopts two support rods for support, and is connected and fixed to the bed body through support rod one. After adjusting the height and angle of the support plate, the support rod two is adjusted to make it effectively support the support plate, so that the support is stable and reliable, the angle of the support plate can be adjusted at will to suit different patients, the angle of the support rod two can be adjusted at will, and the support rod two can always provide effective support, and the applicability is strong, thereby greatly reducing the labor intensity of medical staff and being conducive to improving the efficiency and quality of surgery.

[0013] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0014] Embodiment 1, in combination with Figure 1-3The leg support device with adjustable leg support angle used in unicompartmental replacement surgery comprises an arc-shaped support plate 1 and a support rod 2. A connecting column 3 is fixedly connected to one side of the arc-shaped support plate 1. The connecting column 3 is connected to an adjusting column 4. The adjusting column 4 and the relatively close sides of the connecting column 3 are provided with anti-slip teeth that cooperate with each other. A through hole 2 is provided in the middle of the adjusting column 4. The connecting column 3 is threadedly connected with an adjusting bolt 5. The screw rod of the adjusting bolt 5 passes through the through hole 2 and then is threadedly connected to the connecting column 3. The lower part of the arc-shaped support plate 1 Connecting plates 6 are symmetrically arranged on both sides along the middle, an adjusting column 27 is arranged between the two connecting plates 6, and the relatively close sides of the adjusting column 27 and the connecting plate 6 are provided with anti-slip teeth that cooperate with each other, a through hole 2 is arranged in the middle of the adjusting column 27, one of the connecting plates 6 is provided with a through hole 3, and the other connecting plate 6 is threadedly connected with an adjusting bolt 28, and the adjusting bolt 28 passes through the through hole 3 and the through hole 2 through one connecting plate 6 and the adjusting column 27 and is threadedly connected to the other connecting plate 6; the adjusting column 27 is fixedly connected with a support rod 29. When in use, install the fixing part on the bed. The fixing part is the fixing part used and will not be described in detail here. Insert the support rod 2 into the connecting hole on the fixing part and determine the insertion depth as needed to adjust the height of the arc-shaped support plate 1. Fix it through the locking structure on the fixing part. Loosen the adjusting bolt 5 as needed. At this time, the arc-shaped support plate 1 can be rotated relative to the adjusting column 4 to adjust the angle of the arc-shaped support plate 1. After adjustment, tighten the adjusting bolt 5. At this time, the adjusting column 4 and the anti-slip teeth of the connecting column 3 engage with each other, thereby achieving relative fixation. Similarly, loosen the adjusting bolt 8 and then adjust the angle of the support rod 9 and then tighten the adjusting bolt 8 to make the lower end of the support rod 9 rest on the bed to further support the arc-shaped support plate 1.
