Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present utility model more clear, the technical solutions in the embodiments of the present utility model will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in FIGS. 1-2 , the utility model provides a functional exercise support for total knee arthroplasty, including a first U-shaped tube 1 , a second U-shaped tube 2 , a first telescopic tube 4 , and a second telescopic tube 5 , the load-bearing plate 6, the two sides of the first U-shaped pipe 1 are respectively provided with a plurality of clamping teeth 3, the first telescopic pipe 4, the second telescopic pipe 5 are respectively connected with the two sides of the first U-shaped pipe 1. One end is hinged, the two sides of the second U-shaped tube 2 are hinged with the first telescopic tube 4 and the second telescopic tube 5 respectively, and the bottom edge of the second U-shaped tube 2 is stuck on the first U-shaped tube. The load-bearing plate 6 is fixedly connected with the first telescopic tube 4 and the second telescopic tube 5 in the latching teeth 3 corresponding to both sides of the 1. By the bottom edge of the second U-shaped tube 2 being clamped in different clamping teeth 3, the inclination angles of the first telescopic tube 4, the second telescopic tube 5 and the load-bearing plate 6 can be adjusted to meet the different ranges of motion of patients; The telescopic tube 4 , the second telescopic tube 5 and the load-bearing plate 6 are fixedly connected, and the load-bearing plate 6 forms at least four fixed points (corresponding to the four ends of the load-bearing plate 6 ) with the first telescopic tube 4 and the second telescopic tube 5 , thereby forming With a stable load-bearing bracket, the bracket capacity is enhanced.
