Embodiment 1

[0019] see figure 1 , figure 2 and image 3 , the present invention provides a technical solution: a movable elbow bracket, including two right-angled bending rods 1, the rear side of the right-angled bending rods 1 clamps a clamping block 2, and the clamping block 2 clamps a Schanz screw 3, and the Schanz screw 3 is fixedly installed on the back side of the ulna shaft, the right side of the right-angle bending rod 1 clamps the clamping block 2, and the lower end connecting rod 4 is clamped between the two clamping blocks 2, and the lower end is connected The upper end of the rod 4 is equipped with an adjustable connecting piece 5, and the upper end of the adjustable connecting piece 5 is equipped with a spherical connecting rod 6. The upper end of the spherical connecting rod 6 holds the clamping block 2, and the clamping block 2 holds two Schanz screw 3, and the Schanz screw 3 is fixed to the humeral shaft.

[0020] Specifically, the adjustable connector 5 includes a dis...

Embodiment 2

[0025] A movable elbow support, other features are the same as the first embodiment, the difference is: as figure 1 and Figure 4 Shown:

[0026] Specifically, the clamping block 2 includes a central splint 21, the two ends of the central splint 21 are integrally formed with a hexagonal stopper 22, the two sides of the central splint 21 are fitted with extrusion blocks 23, and one side of the extrusion block 23 is sleeved with a screw 24, and the screw 24 passes through the hexagonal limiting block 22 and is screwed with the other side extrusion block 23, and the opposite surface of the extrusion block 23 and the center splint 21 is provided with a hexagonal limiting block. The hexagonal limiting groove 25 nested with the positioning block 22 , on the opposite surface of the extruding block 23 and the central splint 21 , an extruding groove 26 is formed on the outer wall of the hexagonal limiting groove 25 .

[0027] Working principle: The present invention proposes a clampi...

Abstract

The present invention discloses a movable elbow joint support, the rear sides of two right-angle bent rods clamp Schanz screws through clamping blocks to be fixed to the rear side of an ulnar backbone, the front sides of the two right-angle bent rods and a lower-end connecting rod are clamped together through clamping blocks, the lower-end connecting rod and a spherical connecting rod are installed together through an adjustable connecting piece, and therefore through use of the right-angle bent rod 1, the far-end Schanz screw is driven into a screw at the near end of the ulna and located on the rear side, so that the rotating center of the adjustable connecting piece is located on the outer side, and the operation difficulty of driving the screw into the far end is reduced. By using the adjustable connecting piece, after the fixing screw is loosened, the position of the far-end straight rod connector on the lower-end connecting rod can be adjusted, the fixing screw can be used for locking, and the angle between the upper-end connecting rod and the far-end straight rod connector can be adjusted by loosening the hollow positioning nail, so that the angle can be adjusted according to the bending angle of the arm of a patient, the movable elbow joint support can better meet the physiological activity standard of the elbow joint, and the influence on the anterior wall rotation function is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a movable elbow support. Background technique [0002] Instability of the elbow joint caused by trauma is a common injury of the elbow, most of which require surgical treatment. In some cases, there is still a certain degree of instability after fracture fixation and ligament repair. In this case, external fixation brackets are needed to increase stability and allow early movement of the elbow joint to reduce elbow stiffness and improve curative effect. [0003] The screw at the distal end of the existing movable elbow support is usually placed on the outside of the middle section of the ulna, which is inconvenient to operate, easily causes fractures of the ulnar shaft, and simultaneously limits the rotation function of the forearm. For this reason, a new type of elbow joint movable support is proposed. Contents of the invention [0004] The object of the present inve...
