Adjustable fracture minimally invasive compression fixation guiding device and use method thereof

Abstract

The invention discloses an adjustable fracture minimally invasive compression fixation guiding device, comprising: a connecting seat; a handle grip; an adjusting mechanism mounted on the other side ofthe connector; two guide sleeves are arranged on the outside of the adjusting mechanism, and the axes of the two guide sleeves are parallel; And two bending bars, each bending bar is correspondinglyinstalled on the outside of a guide sleeve, each bending bar comprises a fixedly connected bending bar straight part and a bending bar turning part, the free end of each bending bar turning part is provided with a pair of needle top centers, and the axial line of each guide sleeve passes through the corresponding pair of needle top centers; At least one of the two guide sleeves is cooperated withthe adjusting mechanism, and when the adjusting mechanism is rotated, the spacing between the axes of the two guide sleeves can be changed synchronously. The device can ensure the parallelism betweentwo Kirschner pins drilled into the bone, and the needle tip is accurately aligned with the needle outlet, thus reducing the operation time and the X-ray fluoroscopy times. At the same time, the device is multi-purpose, has the function of compression reduction, improves the operation quality and efficiency, and has little trauma.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an adjustable fracture minimally invasive pressurized fixation guide and a use method thereof. Background technique [0002] Patellar fractures are common clinically, and most patella fractures require surgical treatment. No matter whether open reduction and internal fixation or closed reduction and internal fixation is used for the surgical treatment of patella fractures, the patella needs to be reset, and the fixation after reduction must be stable and reliable without defects such as misalignment and protrusion; The pins are used as fixation or guide; the two Kirschner wires that penetrate into the patella need to be parallel, and the distance between the two pins should be appropriate. The distance between the two sides is moderate, and the length of the two needles on the opposite side of the patella is appropriate. [0003] At present, in patella fracture surgery, the fixat...

AI Technical Summary

Problems solved by technology

[0003] At present, in patella fracture surgery, the fixation surface is not comprehensive enough after reduction, and the fixation is not stable enough. During the fixation process, deviation is prone to occur, and the accuracy is not high; it is difficult to ensure parallelism between the two Kirschner wires penetrating into the patella. Moreover, the distance between the two needles cannot be adjusted precisely; the process of inserting the Kirschner wire basically depends on the clinical experience of the surgeon. Repeated corrections and adjustments are required, which increases the operation time and the number of X-ray perspectives. This not only increases the pain of the patient and the workload of the medical workers, but more importantly, increases the damage to the health of the patient.
