Embodiment 1

[0022] see Figure 1-3 , a positionable 3D printed elbow brace, comprising an upper arm fixing shell 1, a connecting winch 2 is movably connected to the surface of the upper arm fixing shell 1, and the inside of the connecting winch 2 is provided with a clamping groove 3, and the clamping groove 3 The inner wall is movably connected with a connecting ball 4, the side of the connecting ball 4 is fixedly connected with a connecting frame 5, the surface of the connecting winch 2 is provided with a mounting groove suitable for the connecting frame 5, and the connecting frame 5 is fixedly connected with an end far away from the connecting winch 2. The forearm fixing shell 6, the surface of the forearm fixing shell 6 and the upper arm fixing shell 1 are all equipped with Velcro straps, the top surface of the connecting winch 2 is fixedly connected with a connecting sleeve 7, and the inner wall of the connecting sleeve 7 is movably connected with a fixing ball 8. The surface of the c...

Embodiment 2

[0025] see Figure 4 , the surface of the front of the connecting winch 2 near the top is fixedly connected with an elastic fixed rod 10, the top of the elastic fixed rod 10 is fixedly connected with a stabilizing ball 11, and the bottom surface of the fixed ball 8 is provided with a draw-in groove suitable for the stabilizing ball 11, and the stabilizing ball 11 is clamped with the inwall of the draw-in groove, the surface of the fixed ball 8 is provided with anti-slip protrusions, the inwall of the movable groove on the surface of the connection sleeve 7 is provided with an anti-slip rubber pad, and the elastic fixing rod 10 and the number of the connection sleeve 7 are equal. There are two, and the two elastic fixing rods 10 and the connecting sleeve 7 are horizontally distributed on the top surface of the connecting winch 2 .

[0026] The difference from Embodiment 1 is that through the elastic fixing rod 10 and the stabilizing ball 11, the stabilizing ball 11 can be snapp...

Embodiment 3

[0028] see Figure 5-6 , the back side of the connection winch 2 is movably connected with an elbow stabilizing shell 12, and the front side of the elbow stabilizing shell 12 is fixedly connected with an installation ball 13, and the back side of the connection ball 4 is provided with a draw-in groove suitable for the installation ball 13, and the elbow is stable. The front of shell 12 is fixedly connected with L-shaped flap 14, and one end of L-shaped flap 14 away from elbow stable shell 12 is provided with spherical block, and the back side of connecting capstan 2 is provided with L-shaped flap 14 and spherical block. Adapted draw-in slot, the inner wall of the draw-in slot that is set on the surface of the connection winch 2 and is compatible with the connecting ball 4 and the connecting frame 5 is fixedly connected with an elastic clamp block 15, and the front shape of the elastic clamp block 15 is T-shaped, and the elastic clamp One end of the block 15 is movably connecte...

Abstract

The invention discloses a positionable 3D printed elbow joint brace. The positionable 3D printed elbow joint brace comprises an upper arm fixing shell, a connecting winch is movably connected to the surface of the upper arm fixing shell, a clamping groove is formed in the connecting winch, and a connecting ball is movably connected to the inner wall of the clamping groove; By means of the connecting ball and a connecting frame, when the upper arm fixing shell and a forearm fixing shell are damaged, the connecting ball can be directly taken out of the connecting winch, the connecting frame andthe forearm fixing shell can be separated, and different parts of the brace can be replaced conveniently. Meanwhile, due to the arrangement of a connecting sleeve and a fixing ball, during wearing ofa patient, if the elbow needs to be moved, the connecting winch can be far away from the upper arm fixing shell, the connecting relation between the upper arm fixing shell and the connecting winch canbe kept under the action of the fixing ball and the connecting sleeve, and mutual movement of the upper arm fixing shell and the connecting winch is also facilitated, and the effects of being convenient for a patient to use and convenient for replacing damaged parts are achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a positionable 3D printed elbow brace. Background technique [0002] Elbow joint brace is a medical device that is worn on the hand to facilitate the recovery of the elbow after people suffer from elbow fractures or elbow dislocations. With the continuous development of 3D printing technology, it can be printed out by 3D printers. And the elbow brace that can come out is also gradually researched by people. [0003] Among the existing 3D printed elbow braces, although some elbow braces can locate the position of the upper arm, the position of the device needs to be adjusted in advance during use, which is inconvenient to operate. At the same time, due to the The external bracket is a whole that is 3D printed, and when its internal components are damaged, the whole needs to be replaced, which is a waste of resources. Contents of the invention [0004] Aiming at the def...
