CS209724B1 - Swing runner external skeletal fixation - Google Patents

Abstract

The subject of the invention is a swinging runner for external skeletal fixation, which is a connecting and fixing element of a universal skeletal fixation kit. The swinging runner according to the invention consists of two plates, one of which has at least two pins. The second plate is provided with an opening for a compression-distraction device. In the places of the pins, longitudinal through-holes are provided in both plates for defining the swing, through which drill guide sleeves, provided with a safety device, pass. Between these drill guide sleeves there is another drill sleeve, passing through a circular hole and provided with a tightening nut and a safety device. The subject swinging runner can be advantageously used in external skeletal fixation sets intended for the treatment of infected fractures and sub-articular joints.

Description

(54) Pivotable runner of external skeletal fixation

The object of the invention is a pivotable outer skeletal fixation runner which is a connecting and fixing element of a universal skeletal fixation kit.

The swinging runner according to the invention consists of two plates, one of which has at least two suppositories. The second plate is provided with an opening for the compression distraction device. Longitudinal through holes are provided at the locations of the suppositories in both plates to limit the oscillation through which the drill guide bushes, provided with a fuse, pass. Between these drill guide sleeves there is another drill sleeve, passing through a circular bore and provided with a tightening nut and a lock.

The present oscillating runner can be advantageously used in external skeletal fixation kits intended to treat infected fractures and nonunions.

BACKGROUND OF THE INVENTION The present invention relates to a pivotable outer skeletal fixation slider which is the connecting guiding and locking element of this fixation intended to be used in the treatment of open infected fractures and articular joints in the area of long bones. , including their distraction.

To date, mainly gypsum external fixation has been used, which does not provide a good option for the treatment of open infected fractures and articular joints and it is not possible to shorten and lengthen the bones. In other cases, a rigid ruler plate with fixed pitch holes is used, which greatly restricts the choice of sites for insertion of surgical aids - screws or nails - due to the nature of the bone fracture. Other disadvantages are the possibility of compressing only the elasticity of the established surgical aids wrapped in a rubber bandage and the necessity of using special drill sleeves or templates for drilling holes in the plate and bone. Another known fixation element is telescopic fixators with fixed pitch apertures, which also limit the choice of location for the insertion of surgical aids with different bone marrow characteristics. The use of other known frame fixations is also contingent upon the use of drill sleeves or templates to accurately drill holes in the plate and bone. These fixations have the further disadvantage that the displacement of the individual runners along the threaded rod leads to an uneven distribution of the compression of the bone parts and, in addition, a special aiming device has to be used for drilling the holes. As a common drawback of the fixations used so far for single-plane superstable fixation.

The above-mentioned disadvantages of the known fixation methods are eliminated by the multipurpose fixation, the element of which is the pivoting slider according to the invention, which consists in that at least two suppositories are on one plate and

Claims (3)

SUBJECT Pivotable outer skeletal fixation slider consisting of two guide groove plates, characterized in that at least one fixed pin (3) is on one plate (1) and the other plate (2) is provided with an opening (7) for the compression distraction device and both inserts (2) are provided at the point of the suppositories (3) the second plate is provided with an opening for the compression distraction device and both inserts have longitudinal through holes at the point of the suppositories for deflection through which the drill guide bushings pass is another drill guide bushing through a circular bore and provided with a tightening nut and lock. The advantage of the swiveling runner according to the invention is, in particular, the fact that - together with other elements - it enables the formation of rigid rigid skeletons according to individual needs, the attachment of operating aids - screws or nails - and their displacement for perfect bone reduction. Another advantage is the possibility of introducing the operating aids at an angle which can be changed in the direction of the longitudinal axis and thus also the possibility of additional reduction. Another advantage is that it serves as a drill sleeve and forms the reinforcement of the fixing frames. An exemplary embodiment of a runner according to the invention is. 1 in plan and in FIG. 2 in a side sectional view. The pivotable outer skeletal fixation runner consists of two plates 1, 2 with guide grooves. There are longitudinal through holes 4 in the plates 7 and 2, in the center of which there are fixed pins on one of the plates 7. 3. In addition to the longitudinal through holes 8, both inserts 8, 2 are provided with a through hole for the mounting drill guide 9, provided with a nut 6. The rocker drill guide sleeves 8, like the mounting drill guide 9, are equipped with a fuse 5. The longer plate 2 has a at its end, a through hole 8 is provided for the compression distraction device. The present swinging runner can be advantageously used in external skeletal fixation assemblies. longitudinal through holes (8) for limiting the oscillation through which the drill guide sleeves (kf), provided with a lock (5), are provided, wherein between the drill guide sleeves (4) is another drill guide sleeve (9) passing through a circular hole and provided with a tightening nut / 6 / and fuse / 5 /.
