DETAILED DESCRIPTION

The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

Example:

As shown in Figures 1 to 4:

The utility model provides a knee joint puncture bracket, comprising a first fixing plate 11 and a second fixing plate 12, the tops of the first fixing plate 11 and the second fixing plate 12 are both arc-shaped surfaces that fit the legs, which can better fit the legs and increase the comfort of the patient; a first hinge 13 is arranged on one side of the first fixing plate 11, and a second hinge 14 is arranged on one side of the second fixing plate 12 corresponding to the first hinge 13, and the first hinge 13 and the second hinge 14 are rotatably connected by a fixed shaft pin 15, so that the first fixing plate 11 and the second fixing plate 12 can rotate relative to each other to meet the needs of different angles of the patient's legs; in addition, an adjustment component is also arranged at the bottom of the first fixing plate 11 and the second fixing plate 12 for connection, which can realize the angle adjustment and fixation of the first fixing plate 11 and the second fixing plate 12, so that the bracket can better wrap the patient's legs, and then bend the patient's knee joint to a suitable angle for puncture operation, thereby improving the convenience of use and the scope of application.

Please refer to Figures 2, 3 and 4, the adjustment component includes two groups of connecting seats 21, two groups of connecting seats 21 are set at the bottom of the first fixed plate 11, one end of a triangular bracket 22 is connected between the two groups of connecting seats 21 through two groups of screws, and the other end of the triangular bracket 22 is connected to the bottom of the second fixed plate 12; the first fixed plate 11 can be moved up and down relative to the triangular bracket 22 through the thread or slider structure in the connecting seat 21, and the other end of the triangular bracket 22 is fixed on the second fixed plate 12, so that the first fixed plate 11 and the second fixed plate 12 can be adjusted in the vertical direction.

As shown in FIG. 2 , FIG. 3 and FIG. 4 , a rectangular slide groove 23 is provided at the bottom of the second fixed plate 12. This can provide a space for relative sliding between the triangular bracket 22 and the second fixed plate 12. In order to achieve sliding connection, a sliding block 24 is provided at the other end of the triangular bracket 22. The shape of the sliding block 24 matches the slide groove 23 below the second fixed plate 12 so that it can slide smoothly in the slide groove 23. Specifically, the sliding block 24 may be provided with a guide rail or a bearing and other structures, and it can slide along the long side direction of the slide groove 23, which can make the triangular bracket 22 realize simple and flexible positioning adjustment relative to the second fixed plate 12. Through the fixed connection between the connecting seat 21 on the first fixed plate 11 and the triangular bracket 22, and the sliding movement of the sliding block 24 below the triangular bracket 22 in the slide groove 23, the relative movement of each part in the adjustment component can be realized, thereby flexibly adjusting the spacing between the two fixed plates in the vertical direction.

Please refer to Figures 3 and 4, the adjustment component also includes a telescopic cylinder 25 and a telescopic rod 26. Two groups of fixing seats 27 are provided at the bottom of the first fixed plate 11. The telescopic cylinder 25 can be rotatably installed between the two groups of fixing seats 27, and one end of the telescopic rod 26 is connected to the telescopic cylinder 25. At the same time, a connecting hole is also provided on the triangular bracket 22, and the other end of the telescopic rod 26 is fixedly connected to the connecting hole through a rotating structure. Through the telescopic movement of the telescopic rod 26 in the telescopic cylinder 25, the triangular bracket 22 can be moved forward and backward relative to the first fixed plate 11, thereby adjusting the distance between the two fixed plates.

When the position and angle of the puncture bracket need to be adjusted to adapt to the different leg shapes of patients, the doctor can start the telescopic cylinder 25 to drive the telescopic rod 26 inside it to move forward and backward. One end of the telescopic rod 26 is fixed to the triangular bracket 22 through a connecting structure, so its movement will directly drive the triangular bracket 22 to move forward and backward relative to the first fixed plate 11; the position of the triangular bracket 22 is fine-tuned, so that its angle and position can be adjusted to the optimal position of the patient's leg to obtain the best support effect.

As shown in FIG. 4 , the first fixing plate 11 is provided with two groups of first female Velcro 16 on one side, and the second fixing plate 12 is also provided with a second female Velcro 17 at a corresponding position; at the same time, the other side of the first fixing plate 11 is provided with two groups of first male Velcro 18, and the two groups of first male Velcro 18 are respectively attached to the two groups of first female Velcro 16 of the first fixing plate 11; the other side of the second fixing plate 12 is also provided with a second male Velcro 19. The second male Velcro 19 is attached to the second female Velcro 17 on the second fixing plate 12.

The bracket can be quickly installed or removed by connecting with the female and male Velcro on both sides. Compared with the traditional bracket that needs to be assembled with screws or other connection methods, the connection method of female and male Velcro can significantly save the doctor's preparation time before the puncture operation, and can also remove the bracket more quickly after the puncture. In addition, quick disassembly can also bring patients a more relaxed and comfortable experience after the puncture, avoiding the discomfort caused by wearing the bracket for a long time.
