Abstract

The invention belongs to the field of medical instruments, and particularly relates to a fine-adjustment fracture fixing frame. The fine adjustment fracture fixing frame comprises two lead screws which are perpendicular to each other, wherein fine adjustment bodies are arranged on the two lead screws; each fine adjustment body is provided with an adjusting part and a follow-up part; the adjustingparts drive linkage sleeves and drive the corresponding follow-up parts to move linearly along the lead screws, and mounting bases used for mounting a bone nail are arranged on the left sides of the follow-up parts of the fine adjustment bodies on the vertical lead screws; and locking pieces are inserted into the mounting bases, and after the locking pieces are screwed, the mounting bases and thefine adjustment bodies are jacked and locked to fix the position of the bone nail. The position of the bone nail is adjusted through cooperation of adjusting nuts and the lead screws, the moving distance of the adjusting nut by rotating for a circle every time can be accurately grasped, fine adjustment of the bone nail position by the fine adjustment bodies is achieved, the offset position of thebone is corrected, the staggered bone is aligned and connected again, and the connecting quality of the fractured bone of a patient after rehabilitation is guaranteed.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a fine-tuning fracture fixation frame. Background technique [0002] Clinically, after limb fractures, the bones need to be fixed to help them recover and heal as soon as possible. Orthopedic external fixation brackets are one of the commonly used medical devices in orthopedic clinics. However, most of the existing external fixation brackets are difficult to adjust, which brings operational difficulties Inconvenience. For example, the Chinese patent application with application number 201210244501.5 discloses a micro-movement three-dimensional external fixation bracket system for orthopedics. Connection, the fixed frame can only be adjusted by the doctor's experience when adjusting, and the adjustment accuracy is low, which brings inconvenience to the doctor's operation and cannot guarantee the patient's rehabilitation quality. Contents of the invention [0003] According t...
