[0003] The distance between each finger is relatively close, and it is inconvenient to perform plaster fixation on the fingers. Excessive external load will affect the patient's hand movement and the recovery and healing of the fingers. Therefore, a fixation splint is used to fix them. However, each person's fingers are of different thicknesses and lengths, and the common fixation splint cannot adjust the length and width according to the patient's needs. Therefore, other problems may arise during later use, such as the fixation splint not matching the patient's injured finger. Utility Model Content

[0024] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] See also Figure 1-4 The utility model provides a technical solution: a fixed splint for fracture rehabilitation that is easy to adjust in length, comprising a movable semicircle 10 slidably connected to a hollow semicircle 11 through a slider and a slide groove 13, one end of the movable semicircle 10 and the hollow semicircle 11 are welded and fixed with a protrusion 14, a secondary limiting belt 21 is engaged with the protrusion 14 through a groove 15 on the outside of the protrusion, and the secondary limiting belt 21 is threadedly fixed to the protrusion 14 through a second bolt.
[0026] The two main limiting belts 20 are respectively engaged and fixed with the movable semicircle 10 and the hollow semicircle 11 through the two limiting grooves 16 , and the two main limiting belts 20 are threadedly fixed thereto through the clamping bolts 22 .
[0027] Working principle: Place both movable semicircles 10 on the outside of the fractured finger. When the finger is longer, pull the movable semicircle 10 toward one end of the finger, so that one end of the movable semicircle 10 slides outward through the slider inside the outer groove 13 of the hollow semicircle 11, so the overall length of the movable semicircle 10 and the hollow semicircle 11 becomes longer, and then wrap the secondary limiting belt 21 around the outer side of the protrusion 14 through the groove 15, pull the two ends of the secondary limiting belt 21 to both sides, and adjust it to the position where it needs to be limited, and then use the bolt 22 to limit its thread on the outside of the secondary limiting belt 21, and then put the two main limiting belts 20 on the limiting groove 16 on the outside of the movable semicircle 10 and the hollow semicircle 11 respectively, and limit them by the same method, so the movable semicircle 10 and the hollow semicircle 11 are limited and fixed on the outside of the finger at the fracture.
[0028] Furthermore, the overall length of the auxiliary limiting belt 21 and the main limiting belt 20 is longer than that of the movable semi-circle 10 and the hollow semi-circle 11, and thus can be adjusted according to the thickness of the injured person's fingers.
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
