Description

An external fixation apparatus for rib fractures

The present invention relates to an apparatus which can effectively fix and stabilize a fractured frame.

Chest trauma and cardiopulmonary resuscitation due to traffic accidents can lead to multiple rib fractures (multiple rib fractures). Multiple rib fractures can lead to hemothorax and pneumothorax due to the fracture of the fracture piece, as well as loss of the support of the ribs during the breathing, which may lead to bilateral chest (or chest, flail chest) . Especially, when three or more consecutive ribs are fractured at both ends, bilateral thoracic chest often occurs. When a patient's chest is inspected, the patient does not support the ribs and collapses toward the thoracic cavity when the patient is inspirated, resulting in inadequate aspiration and acute respiratory failure. Sonata chest can last up to four weeks when rib fractures are treated. Continuous positive pressure respiratory therapy is needed to treat respiratory failure due to bilateral chest trauma.

The method of fixation of multiple rib fractures is to fix the fractured ribs surgically, but only when severe rib fracture due to rib fracture is severe. On the other hand, a method of fixing the rib fracture from the outside is not yet developed.

Therefore, in a case where a rib is broken, a device capable of effectively securing a fractured rib without surgery is required.

Chest trauma and cardiopulmonary resuscitation due to traffic accidents can lead to multiple rib fractures (multiple rib fractures). Multiple rib fractures can lead to hemothorax and pneumothorax due to the fracture of the fracture piece, as well as loss of the support of the ribs during the breathing, which may lead to bilateral chest (or chest, flail chest) . Especially, when three or more consecutive ribs are fractured at both ends, bilateral thoracic chest often occurs. If the chest is bilateral, the patient does not support the ribs during inspiration, collapse into the thoracic cavity, resulting in inadequate aspiration and acute respiratory failure. Sonata chest can last up to four weeks when rib fractures are treated. Continuous positive pressure respiratory therapy is needed to treat respiratory failure due to bilateral chest trauma.

The method of fixation of multiple rib fractures is to fix the fractured ribs surgically, but only when severe rib fracture due to rib fracture is severe. Therefore, there is a need for an apparatus capable of stabilizing and stabilizing the thoracic deformity caused by a rib fracture by an operation other than an operation.

1 is a front view showing an example of a frame fixing device 10 of the present invention. 2 is a perspective view showing an example of the frame fixing device 10 of the present invention.

A rib fixation device (10) is used to fix a fractured rib in a patient with multiple rib fractures. The frame fixation device 10 has a structure capable of fixing the fractured frame region in a state in which it is supported in a normal frame portion existing around the fractured frame, and in a pulled state (a state in which tensile force is applied).

To this end, a rib fixation device (10) according to an embodiment of the present invention is a structure for fixing a rib fracture part of a patient, comprising: a chest supporting means (11) for supporting a peripheral part of a rib fracture part; Suction means (19) which is adsorbed to the rib fracture site; And pulling means (14) for pulling the suction means (19) in the direction of the chest supporting means (11).

Hereinafter, a concrete fixing method for each configuration will be described.

First, the chest supporting means 11 may be placed on the unfractured chest around the fractured frame, and then the suction means 19 may be attached to the fractured site. That is, the chest supporting means 11 can serve as a frame for fixing the frame fixing device 10 to the normal chest area. Particularly, even if a tensile force is generated by the suction means 19, it can support the reaction force to induce the reaction force in the outward direction of the body.

The chest support means (11) comprises at least two support legs (12-1, 12-2) in contact with the peripheral portion; And a body portion 13 connected to the two support legs 12-1 and 12-2. The body part 13 is connected to the two support legs 12-1 and 12-2 and is spaced apart from the rib fracture part by a predetermined distance to form a predetermined space with the body corresponding to the rib fracture part .

The chest supporting means 11 may be made of a plastic deformable material. That is, the chest supporting means 11 can adjust the degree of bend and width according to the position and extent of the rib fracture. The shape of the ribcage or the position of the rib fracture may vary from one person to another, as it can not be used in various situations when only one shape is present. In this case, the material may include plastic, aluminum, or an aluminum alloy.

In the example shown in FIGS. 1 and 2, the support legs 12-1 and 12-2 are illustrated as two, but the present invention is not limited thereto. In addition, the present invention is not limited to the above-described leg shape but may be included in the rib fracture apparatus 10 of the present invention if it is capable of supporting a region other than the rib fracture region.

The body portion 13 is disposed at a predetermined distance from the rib fracture site so that the absorption means 19 is located at the rib fracture site. In other words, it may be arranged so as to be spaced apart so as to provide a space for the adsorption means 19.

The absorption means (19) can be adsorbed to the rib fracture site. At this time, the method of adsorption will not limit the constitution of the present invention. For example, an adhesive may be applied to the surface of the suction means 19 and adsorbed to the rib fracture site. Alternatively, an air-absorbing pad may be provided to be adsorbed to the rib fracture site. In addition, the suction means 19 may be provided so as to be adsorbed to the rib fracture site by combining various methods including the two methods.

It may be pulled and fixed in the direction of the chest supporting means 11 through the pulling means 14 in a state in which the suction means 19 is adsorbed to the rib fracture site. The pulling means 14 may pass through the body portion 13 of the chest supporting means 11 and be fixed therethrough. When the suction means 19 is pulled, tensile force is generated in the outward direction with respect to the body surface, so that a phenomenon of collapse of the fractured frames into the inside of the body can be prevented.

The pulling means 14 may have a circular or polygonal columnar shape with a plurality of grooves formed along the longitudinal direction.

The pulling means 14 connected to the suction means 19 is pulled up to pull the fractured portion of the frame and then the pulling means 14 is fixed to the fixing device in the chest supporting means 11, It can be stabilized (fixed).

The chest supporting means 11 can be fixed by adjusting the bending and length to adjust to the bending and fracture range of the chest. The suction means 19 can also be adjusted according to the extent of the fracture by allowing the width and length to be adjusted according to the fracture range.

The pulling means 14 will be described in detail with reference to Fig.

3 (a) and 3 (b) are diagrams showing pulling means 14 according to an embodiment of the invention. Fig. 3 (a) shows a perspective view of the pulling means 14, and Fig. 3 (b) shows a cross-sectional front view of the pulling means 14. Fig.

As shown in Fig. 3, the pulling means 14 may have at least one groove 22 in the shape of a column along the longitudinal direction. The at least one groove (22) is formed for fixing by means of a fixing means (16).

The fastening means 16 is provided with a protrusion 15 corresponding to the groove 22 so that any one of the plurality of grooves 22 in the state in which the pulling means 14 penetrates the body portion 13 The protruding portion 15 is fitted to the body portion 13 so that the pulling means 14 can be fixed to the body portion 13. The protrusions 15 may be coupled to the fixing means 16 by elastic means or the like so that the protrusions 15 can be held in any one of the plurality of grooves 22 even when the user does not exert any force. If the position of the fastening means 16 is moved and released in a state where the protruding portion 15 is pulled out, when the user tries to change the position of the groove to be inserted in the plurality of grooves 22, The protruding portion 15 may be modified to be inserted.

When the fixing means 16 is fixed to the groove 22 at the desired position, the movement of the projection 15 can be fixed by using the fixed-portion cap 18. That is, the user may close the fixed cap 18 to fix the engagement position of the groove 22, and open the fixed cap 18 to change the engagement position of the groove 22. [

Further, the pulling means 14 may further include a head 21 at one end of a columnar shape. The head 21 is provided to be larger than the width (or width or radius) of the columnar shape and can be coupled to the suction means 19 and pulled in the direction of the chest supporting means 11. That is, the suction means 19 is provided with a hole which is larger than the width (or width or radius) of the columnar shape and smaller than the width (or width or radius) of the head 21, 14 are fitted, the hole is caught in the head 21 and can be pulled by the pulling means 14.

Hereinafter, a concrete method of applying the rib fixation device 10 of the present invention to a fractured portion and a normal portion of a rib fracture patient will be described.

FIGS. 4 to 6 are views showing an example of applying a rib fixation apparatus 10 of the present invention to a rib fracture site of a patient according to an embodiment of the present invention. The order is arbitrarily described for ease of understanding, but is not limited to this application order.

Referring to Figures 4-6, the patient's frames 41-1 through 41-4 are shown, the first and fourth frames 42-1 and 42-4 are shown as normal frames, 3 The frames (42-2 and 42-3) are assumed to be fractured frames. The position of the normal frame is the normal area 42-1, and the position of the fractured frame is referred to as the fracture area 42-2.

The suction means 19 of the frame fixing device 10 of the present invention is placed in the fracture region 42-2. The suction means (19) is coupled with a pulling means (14). The adsorption means (19) adsorbs in the fracture region (42-2).

Then, the chest supporting means 11 is placed in the normal region 42-1. Specifically, the two legs 12-1 and 12-2 of the chest supporting means 11 can support the two normal regions 42-1 with the fracture region 42-2 at the center.

In this state in which the chest supporting means 11 is positioned, the pulling means 14 coupled with the suction means 19 can be pulled upward through the chest supporting means 11. The pulling force may be obtained from the physician, the patient himself, or the machine to which the above-mentioned frame fixing device (10) (11) is applied. When the pulling means 14 is pulled in the upward direction (the arrow direction in the drawing), the pulling force is similarly transmitted (the force in the downward arrow direction) to the suction means 19 adsorbed to the fracture region 42-2, Will be.

FIG. 6 shows a state in which a certain level of pulling force is applied. It is confirmed that the fracture region 42-2 is shown partially pulled.

In this state, when the fixing means 16 is inserted into the groove of the pulling means 14, the state in which the pulling force is applied to the fracture region 42-2 may be maintained. In particular, when adjusting the position of the pulling means 14 fitted in the groove, the degree of the desired pulling force can be adjusted.

In this fixed state, it is possible to prevent the collapse that may occur in the fracture region 42-2 due to the fracture of the rib, minimize the pressure applied to the rib, and reduce the pain of the patient Lt; / RTI > Furthermore, since the movement of the fractured part can be caused by the patient's breathing or movement, the movement can be minimized, so that the restoration can be expected even faster.
