Embodiment

[0027] Example: as attached figure 1 , 2 , 3, 4, 5, 6 and attached Figure 7 As shown, a locking and pressurizing chest wall external fixation device includes an external fixation plate 1, which is arranged on the external fixation plate 1 and passes through the chest wall 2, and is used to push the chest wall by expanding and pulling outward. The softened and collapsed chest wall 2 presses outwards on the external fixation plate 1 to pass through the expansion unit 3 for external fixation of the chest wall.

[0028] The fixation plate in the prior art usually adopts the method of adhesive bonding, which is used to locally limit the softening of the collapsed chest wall and reduce the movement of the fracture, but it sacrifices the chest cavity volume, restricts the respiratory movement, affects the respiratory function, and the fixation effect is limited , currently not advocated clinical use.

[0029] In this embodiment, the method of using the fixation device is as follo...

Abstract

The invention belongs to the technical field of medical devices for treating rib fracture, and in particular relates to a locking compression thoracic wall external fixation device. The locking compression thoracic wall external fixation device comprises an external fixation plate, and a penetrating expansion unit which is arranged on the external fixation plate, penetrates through the thoracic wall, and outwards presses the softened and collapsed thoracic wall to the external fixation plate in an expansion and outwards traction jacking manner for realizing external fixation of the thoracic wall. The invention aims at providing the locking compression thoracic wall external fixation device, after an expansion ball is inserted into the thoracic wall, the softened and collapsed thoracic wall is outwards pulled and jacked up and outwards pressed on the external fixation plate, and thus the purpose of active fixation is achieved. The locking compression thoracic wall external fixation device has the advantages that the structure is simple and effective, the thoracic wall fixation stability is good, the fracture end sets and realizes alignment, the fixation effect is good, and the surgical trauma is small.

Description

technical field [0001] The invention belongs to the technical field of medical equipment for treating rib fractures, in particular to a locking and pressurizing chest wall external fixation device. Background technique [0002] The most common case of chest trauma is rib fracture, which accounts for about 90% of the incidence of chest trauma, and the incidence of flail chest due to multiple rib fractures accounts for 15%-25%. Multiple rib fractures can cause severe pain, intrathoracic hemorrhage, or even hemorrhage in the patient due to the swing of the fracture ends, and due to the lack of bony connection, the chest wall is affected and lacks support at the front and rear ends of multiple rib fractures, resulting in softening and collapse of the chest wall This phenomenon brings certain damage to the movement integrity of the thoracic cage. In severe cases, it can lead to mediastinal oscillation and abnormal respiratory movement, which can lead to respiratory failure, pulmo...
