Description

Technical Field

[0001] The invention relates to medical equipment, in particular to an orthopedic reduction and fixation frame. Background Art

[0002] After a human bone is fractured, a stent is needed to temporarily fix the position of the broken bone. After the fracture is healed, the stent will be removed.

[0003] Prior art, patent application number 202122520446.5 discloses a unilateral external fixation bracket for rat long bone fractures, comprising a connecting rod, a first fixing rod, a second fixing rod, a fixing block and a threaded pin; the first fixing rod is rotatably connected to one end of the connecting rod, and the second fixing rod is threadedly connected to the other end, and multiple fixing blocks are respectively fixed on the first fixing rod and the second fixing rod, each fixing block is provided with a threaded pin that can be inserted into the long bone of the rat, and by rotating the connecting rod, the rat long bones can be spliced ​​and an axial tightening force can be applied to prevent the rat long bones from being separated again after splicing; a fixing frame is provided on the connecting rod, an adjusting rod is threadedly connected to the fixing frame, and a connecting pressure plate is rotated at the end of the adjusting rod to limit the relative rotation between the first fixing rod and the connecting rod, thereby preventing the connecting rod from rotating again after the long bones are fixed, causing the connected long bones to be separated again.

[0004] Among them, "a fixing frame is arranged on the connecting rod, an adjusting rod is threadedly connected to the fixing frame, and a connecting pressure plate is rotated at the end of the adjusting rod to limit the relative rotation between the first fixing rod and the connecting rod"; since the pressure plate is pressed on the circumferential surface of the first fixing rod by using the fixing frame and the adjusting rod, the fixing frame of the cantilever beam structure is prone to deformation, so the adjusting rod cannot be pressed tightly after a long time.

[0005] In addition, the above-mentioned prior arts are all connected and fixed by threads. In the event of an accidental collision or the patient's own bored rotation of the threaded component, the threaded component will rotate. After the connecting rod rotates relative to the first fixing rod and the second fixing rod, the length of the connecting rod, the first fixing rod and the second fixing rod changes, causing the direct stress of the two broken bones to change (causing the bone cracks to not fit together), which is not conducive to the healing of the broken bones. Summary of the invention

[0006] In view of the above-mentioned shortcomings in the prior art, the present invention provides an orthopedic reduction and fixation frame.

[0007] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:
