Definitions
- the present invention relates to a linear expander device usable in the progressive correction of skull and face deformations.
- Bone growth disorders Absence or limitation of regeneration and even resorption. These surgical techniques involve a very wide dissection of the soft tissues and particularly of the periosteum. The rupture of the osteoperiosteal complex harms both tissues, which despite coming from two different tissue lines constitute a perfect example of symbiotic coexistence.
- the periosteum helps bone development through the cambrium and, subsequently, offers nutritional support to the cortex through its vascular network.
- the bone pieces completely separated from the remaining tissues behave as authentic free autografts, which in their ischemic phase give rise to irreparable damage to the growth nuclei and promote reabsorption and / or absence.
- Regeneration The resorption process is also one of the causes of long-term failures of techniques that use bone grafts in reconstruction.
- ocular motility disorders are very common. In some cases, these alterations appear to be primary due to an alteration of the external muscles of the eye, however in others, perhaps in the majority, they are due to morphological disorders of the orbit, as evidenced by the improvement of some of the alterations. after corrective osteotomies. But we also know that these operations can make the situation worse or even create and / or make it irreversible. This has been attributed to surgical manipulation.
- linear expanders The principle of operation of the devices that we have called “linear expanders” is similar to that of soft tissue expanders that currently exist on the market: introduction of an extensible balloon inside the tissues and spatial increase thereof through injection progressive saline solution through a subcutaneous valve.
- the expanders used to increase the breast volume of women Descriptive references of these devices can be found in patents EP183496, EP338701, EP324234, EP411767, all of them in the name of Dow Corning.
- the essential difference of the invention with the prior art is that in conventional expanders the expansive force is manifested in a multidirectional manner, being limited only by hard anatomical structures and, in certain types of expanders, by non-membrane elastic located on one of their faces. While in the "linear expanders", object of the present invention, the energy is transmitted in a unidirectional direction. This circumstance The control of the direction of tissue expansion opens up unprecedented perspectives for the application of these devices both to act on soft tissues and on the bone skeleton.
- the expanders described in the present invention transmit the energy in a linear sense.
- the 'appliances would be completely internal and would allow adjustment of the expansion process. They should be as small and flat as possible, as well as soft edges to avoid decubitus.
- Figure 1 Top view of the four anchor point linear expander (5), with movable element (4), fixed box (9), inflatable element (1) by tube (2) coupled to the fluid injection point (3) . Detail of the retention in ratchet (8) between facing walls.
- Figure 2 Detail of the mobile and fixed separating ends, in the form of a hook (7 and 6), of the linear expander. Top flap (7 ') of the free end of the moving element.
- Figure 3 Representation of the movement of the moving element due to the hydraulic / pneumatic pressure emitted by the supply of fluid to the inflatable element.
- Figure 4 Side view of the linear piston expander with hook-shaped end, anchored to the skull bone.
- Figure 5 Detail of the ends (fixed and mobile) in the form of a hook and of the opening of introduction in the skull of the same, of the linear expander.
- Figure 6 Representation of the separation action exerted by the combination of two linear piston expanders, with a hook-shaped end, on the cranial bones.
- Figure 7 Top view of retractable linear expander with mobile inner box (10) and fixed outside (11) with a single anchor point (5), with detail of the retention of ratchet (8) between facing walls.
- Figure 8 Lateral view of the anterior expander device, where the ends of both hook-shaped boxes (6 and 7) are observed.
- Figure 9 Top view of linear expander with blunt end plunger (4 ') for nasal corrections, with detail of ratchet retention between facing walls.
- Figure 10 Side view of linear expander with blunt end plunger for nasal corrections, with detail of flexible joint area with the tube (12).
- Figure 11 Frontal representation of the linear plunger expander with blunt end, once implanted.
- Figure 12 Lateral representation of the linear piston expander with blunt end without lengthening, once implanted.
- Figure 13 Lateral representation of the linear piston expander with an elongated blunt end, once implanted.
- this type of apparatus consists of a very elongated rectangular box, with very thin, rigid or semi-rigid walls, but not extensible.
- the box is closed at one end and open at the other.
- the closed part houses a small balloon (1) that communicates through a tube (2) with a valve (3) through which a fluid can be injected.
- the rest of the box that constitutes almost 3/4 of the box, has been occupied by a solid piece (4) that appears through the open limb and that can slide through the inside of the box.
- the operating mechanism consists in dilating the balloon when a fluid is injected through the valve, which, being confined in a rigid cavity and fixed on all sides except for one, expands through the latter acting as a piston, which in turn it drives out the sliding piece.
- the box is pro- view of some ears (5) that allow their bone fixation by means of micro screws, which has a hook (6) directed inwards, at its open end and that rests on one end of the osteotomy.
- the sliding part is also provided with another hook-shaped edge (7) oriented in the opposite direction, which rests on the other end of the osteotomy.
- the free end also ends in a flap (7 ') that rests on the bone tissue in separation.
- the force exerted by the projection of the balloon (1) when fluid is injected through the valve (3) will produce a progressive separation of the osteotomy line and consequently an expansion of the cranial cavity.
- a ratchet action mechanism (8) is arranged which prevents the recoil of the sliding part (4) in the event that the pressure in the balloon (1) decreases or ceases ).
- the apparatus consists of two boxes of elongated, very flat, thin walls and constructed as the previous ones of a rigid or semi-rigid material, but not extensible. Both boxes are open for one of their extremes and are likely to be introduced into each other.
- the inner box (10) houses in its entirety a balloon (1) that communicates by means of a tube (2) with a valve (3) through which a fluid can be injected.
- the principle of operation is the same as described in the embodiment of Figures 1 to 6 and consists in the dilation of the balloon when a fluid is injected through the valve.
- Said balloon being confined in the inner box (10) expands through its open limb and pushes the bottom of the outer box (11) in the opposite direction, acting as a whole as a telescopic system also provided with a ratchet retention mechanism (8) between both boxes to prevent recoil in case of pressure loss in the balloon.
- Both the inner box (10) and the outer box (11) are topped by two hook-shaped edges (6 and 7) oriented in opposite directions and resting respectively on each of the ends of osteotomy The force transmitted by the injection of the fluid produces a progressive dilation of the osteotomy line and therefore an expansion of the cranial cavity or facial mass.
- the outer box (11) is provided with a lug (5) that allows its fixation to the bone by means of a micro screw or a wire. A similar fixation may be necessary in some cases for the inner box (10).
- the applications of the linear expanders object of the invention are not limited only to the expansion of cranial bones. They may also be used with some variants for the expansion of soft tissues, such as very short noses of congenital, posttraumatic or yatrogenic origin.
- the embodiment of the expander shown in Figures 9 to 13 is applied.
- the most significant modification consists in the suppression of the hook-shaped ends (6 and 7). and in the formation of a blunt-shaped thickening (4 ') at the end of the sliding piece (4) to push the cartilage of the nose.
