Problems solved by technology

[0002] Clinically, comminuted fractures of the phalanx are sometimes difficult to deal with, especially when the skin condition of the open injury is poor, the timing of surgery is difficult to grasp, and early treatment problems appear
Plaster and braces can be used as temporary external fixation devices for auxiliary treatment, but it is only a simple temporary fixation for skin and soft tissue conditions that are accompanied by angulated fractures and lateral displacement; Good reduction of the fracture often leads to poor reduction, and the plaster brace needs to be bandaged, and it is not convenient for us to change the dressing to observe the changes of the condition

Abstract

The invention relates to a simple phalange distraction device. The simple phalange distraction device comprises a first length regulator and a second length regulator which are symmetrically arranged. The first length regulator comprises a rod sleeve with an inner screwed hole, two ends of the rod sleeve are respectively provided with a left screw and a right screw, the threaded connection ends of the left screw and the right screw are respectively in threaded connection with two ends of the rod sleeve, the other end of each of the left screw and the right screw is provided with a fixedly-connected collar, the second length regulator has the same structure as the first length regulator, a left kirschner wire and a right kirschner wire are respectively arranged at two sides of the first length regulator and the second length regulator, the left screws of the first length regulator and the second length regulator are respectively connected with two ends of the left kirschner wire through collars respectively connected with the left screws, and the right screws of the first length regulator and the second length regulator are respectively connected with two ends of the right kirschner wire through collars respectively connected with the right screws. The simple phalange distraction device is simple in structure, convenient to use, low in making cost and good in usage effect.

Description

technical field [0001] The invention relates to an auxiliary appliance used in the clinical technical operation process before or during the treatment of comminuted phalanx fractures, in particular to a simple phalanx spreader. Background technique [0002] Clinically, comminuted fractures of the phalanx are sometimes difficult to deal with, especially when the skin condition of the open injury is poor, the timing of surgery is difficult to grasp, and early treatment problems appear. Plaster and braces can be used as temporary external fixation devices for auxiliary treatment, but it is only a simple temporary fixation for skin and soft tissue conditions that are accompanied by angulated fractures and lateral displacement; Good reduction of the fracture often leads to poor reduction, and plaster braces need to be bandaged, and it is not convenient for us to change dressings and observe changes in the condition. Contents of the invention [0003] The invention provides a s...
