Fracture paratope machine

Abstract

The invention relates to a fracture contraposition machine, which is characterized in that a lead screw neck is sleeved in a shaft hole at a main supporting plate; a lead screw nut is fixedly connected with an auxiliary supporting plate; one end of a guiding bar is fixed at the main supporting plate while the other end interpenetrates in a guide sleeve connected with the auxiliary supporting plate; a concave annular sidestep is arranged at each inner side of each upper central section of the main and auxiliary supporting plates respectively; an arc guide strip hole is arranged on the annular sidestep; an annular angle-adjusting disk is wedged at the annular sidestep; a guidepost pin is arranged in the arc guide strip hole with the lower end sleeved on the angle-adjusting disk; a regulating gear meshed with the sawteeth at the edge of the angle-adjusting disk is arranged in a gear hole at the supporting plate; a steel nail hanger or a clamping device is arranged in the arc strip hole of the angle-adjusting disk; a retaining sleeve frame is arranged at the lower part of the main or auxiliary supporting plate. The invention has the advantages that the contraposition error rate is very low; the invention has strong reliability to help patients recover completely; the complete cure rate is up to 95%; the surgery time and sealing time are both shortened by more than one third; the invention not only lightens the suffering of patients but also saves the cost for medical service.

Description

technical field [0001] The invention relates to a medical device for treating fractures. Background technique [0002] For many years, the methods for treating fractures include splint external fixation, surgical incision plate internal fixation, and external stent fixation. None of these methods solves the problem of accurate alignment of the fractured parts. So far, as long as the two broken ends of the fracture can be offset by no more than two-thirds and the limbs can be shortened by no more than 2 centimeters, it meets the national standard. Even this low standard is hard to meet. Due to poor alignment, bone regeneration time is prolonged, or permanent bone gaps are left, resulting in malunion of the fracture site, and normal function cannot be fully restored; some cannot be cured due to poor alignment, resulting in disability. If the internal fixation with steel plate is used, a second operation is required to remove the steel plate, which increases the pain and fin...

AI Technical Summary

Problems solved by technology

Even this low standard is hard to meet

Due to poor alignment, the time for bone regeneration is prolonged, or permanent bone gaps are left, resulting in malunion of the fracture site, and the normal function cannot be fully restored; some cannot be healed due to poor alignment, resulting in disability

If the plate internal fixation is used, a second operation is required to remove the plate, which increases the pain and economic burden of the patient and prolongs the healing time
