Phalanx retractor

Abstract

A phalanx retractor comprises a bearing seat, wherein two vertical rods are arranged on the bearing seat, a cross rod and a rotating rod are arranged between the two vertical rods, a movable pulley for guiding a traction rope is arranged on the cross rod, and a winch wound with the traction rope id arranged on the rotating rod. A locking nut is arranged at one end of the rotating rod, the other end of the rotating rod outwards extends to form a handle, the handle is provided with a limiting plate matched with the locking nut, the winch arranged on the rotating rod is wound with the traction rope, the other end of the traction rope is connected with a traction bow through the movable pulley, and two ends of the traction bow are connected with two ends of a kirschner wire respectively. A cushion plate connected with the bearing seat is arranged below the traction bow, and multiple phalanx fixing bands are arranged on the other side of the cushion plate. The length of fractured phalanxes can be effectively recovered, formed angles and side displacement are corrected, and phalanx alignment lines are recovered. The phalanx retractor can also serve as simple and fixed treatment for a patient suffering from comminuted fracture but having poor skin conditions.

Description

technical field [0001] The invention belongs to orthopedic auxiliary treatment appliances, in particular to a phalanx tractor. 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 for those with poor skin and soft tissue conditions, accompanied by angulation of fractures and lateral displacement, they can only play a simple temporary fixation role; for displaced fractures, often lead to The reduction is not good, and the plaster needs to be bandaged, and it is not convenient for us to change the dressing to observe the changes of the condition. Contents of the invention [0003] In order to make up for the deficiencies in the existing phalanx fracture treatment process, ...
