Description

Outer protective sleeve on outer fixing device

Technical Field

The utility model relates to a medical article which can be used as a reusable protective article when an external fixator (hereinafter referred to as an external fixator) is used for treatment, an auxiliary sanitary article for limbs after operation and a protective article for an external fixator component.

Background

Treatment of the osteosynthesis procedure involves the installation of external fixators on the bare limb. In this case, the bone anchors, steel pins or bone screws are passed directly out of the bone through the soft tissue. Therefore, it is necessary to protect the limb to which the external fixator has been attached from adverse effects of the external environment. Sanitary protective sheaths are used for this purpose.

Known protective and cosmetic protective covers for external fixators (data source [1]: patent US 7887495, 17.10.2008). The protective sleeve [1] is made of water-washable waterproof fabrics such as vinyl, chloroprene rubber, nylon and the like, and the shape and the size of the protective sleeve are consistent with those of the external fixator. It comprises a webbing that passes through the fabric to tighten the top or bottom edge and also to create an opening through which the limb can pass. Comprising means for joining the edges of the layers in the parting zone, designed as zippers, buttons, knots, hook and loop fasteners. The edges of the fabric are overlapping. Including an insertion window with a vent. The vent includes an open mesh screen. One vent contains one fan. Comprising a support surface for fixing to an external fixator. A rubber sole fixed on the fabric by bonding or sewing.

Protective sheaths are known (from [2] patent RU 95514, 22.12.2009), made of a single layer of soft, flexible cloth, woven or non-woven material, allowing the free circulation of air. The method comprises the following steps: fixing devices on two opposite (folded) side surfaces of the main body cloth are made into zippers to keep the main body in a folded state; a rope-like tightening member is inserted into a passage along the edge of a fabric (webbing) and tightens a protective sleeve to fit closely to the limbs. The channel is formed by bending and stitching the cloth along the edges where the tensioning members are placed. The body cloth has two tensioning members disposed on opposite sides and holds the sleeve in close proximity to the limb from the two opposite open sides. The protective sleeve can be made in the form of a tube with two straps or a boot for receiving the ankle and the foot, which is closed on one side and has a strap in the region of the lower leg.

Known external fixator foot protection covers (origin [3]: patent RU 174651, 30.03.2017). The protective sleeve is composed of multiple layers of flexible cloth, and is provided with an elastic special-shaped sole, cold-proof rubber and a woven belt and a zipper lock inside. The flexible cloth is composed of an outer layer windproof moisture-proof breathable fabric, an inner layer breathable heat-insulating material and a soft breathable allergy-free textile fabric base material.

During the course of a trans-osteosynthesis treatment, it is possible to vary the design of the external fixator, to vary the position of the structural elements of the external fixator, to vary the surface area of the limb and of the external fixator to be protected. A protective sleeve [ 1; 2; 3] do not allow for size adjustment, nor do they have structural components that allow for the length of the protective sheath (along the length of the limb) or its transverse dimension to be changed in the area between two tension members located on opposite sides of the body portion. Furthermore, the size of the limb varies from patient to patient, and the size of the sleeve, both longitudinally and transversely, should be such as to completely cover the limb and the exposed portion of the external fixator, which would not be possible without resizing.

Thus, the protective sleeve [ 1; 2; 3] it does not allow size adjustment, nor does it allow the sheath to be adjusted in height, width, and volume. When treating a curved foot or extension of a limb, the patient cannot adjust the length of the protective sleeve, such as the length of the heel and toes, which causes inconvenience when walking. For example, when the design of the external fixator is changed, the patient cannot adjust the length of the protective sheath. When installing new parts they may be exposed to the outside, and when removing the external fixator parts the protective sleeve may become too large and the unused part may cause inconvenience.

SUMMERY OF THE UTILITY MODEL

The technical result is that the size of the protective sleeve can be adjusted. The multifunctional protective sleeve is ensured by adjusting the height, the height of the heels and the toes and the internal volume.
