However, clinical use shows that due to the structure of the closed ring, even if the knee joint and the ankle joint of a patient are not fixed by the bracket during the fixing period, the moving range of the knee joint and the ankle joint is limited, and particularly after the existing external fixing bracket is used for a long time, the formation of adhesive bands in the knee joint and the ankle joint is easily caused, and the moving capability of the two joints of the patient is directly influenced.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention is directed to a tibial external fixation bracket that facilitates articulation, thereby solving the above-mentioned problems caused by the structural limitations of the bracket.

The utility model adopts the technical scheme as follows:

the utility model provides a shin external fixation support convenient to joint activity, include and wear to establish a plurality of annular parts of connection by a plurality of pillars, wherein, be located the top and the bottom the arc opening has all been seted up to annular part, and two arc open-ended opposite directions.

In at least one possible implementation, the arc-shaped opening is a quarter of a circular arc.

In at least one possible implementation manner, smooth arc structures are arranged at two ends of the arc-shaped opening.

In at least one possible implementation manner, the two ends of the arc-shaped opening are provided with anti-abrasion devices.

In at least one possible implementation manner, the anti-abrasion device comprises a soft sleeve sleeved at the end heads of the two ends of the arc-shaped opening.

In at least one possible implementation, the wear prevention device includes a gasket disposed on the inner side of each end of the arc-shaped opening.

In at least one possible implementation manner, the pad is made of sponge or gel.

The utility model discloses a main design concept lies in, on current external fixation support structure basis, reform transform the closed ring part of top and bottom, according to knee joint and ankle joint's position and home range, set up out the arc opening with the ring at this both ends, thereby wearing to take off, wear the in-process, showing the convenience in use that has promoted the patient, especially can make patient's knee joint and ankle joint carry out abundant activity, avoided current support to receive the problem of obvious influence at this two joint mobility that leads to after wearing for a long time.

Drawings

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described with reference to the accompanying drawings, in which:

fig. 1 is a schematic structural view of a tibial external fixation frame convenient for joint movement according to an embodiment of the present invention.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

The utility model provides an embodiment of shin external fixation support convenient to joint activity, particularly, as shown in fig. 1, include a plurality of annular part 2 of wearing to establish the connection by a plurality of spinal branch posts 1, wherein, be located the top and the bottom annular part 2 has all seted up arc opening 3, and two arc opening 3's opposite orientation. When the knee joint support is worn, the upper end arc-shaped opening 3 faces the rear side of the lower leg, and the lower end arc-shaped opening 3 faces the front side of the lower leg, so that when a patient bends the knee, the upper end arc-shaped opening 3 provides a movement space for the patient, and the knee joint can move in a full range without being hindered by the support; when the ankle joint of the patient dorsiflexes, the arc-shaped opening 3 at the lower end provides a moving space for the ankle joint, and the ankle joint is not influenced by the bracket any more.

In connection with practical use, the size of the arc-shaped opening 3 is related to the range of motion of the knee joint and the ankle joint, and in consideration of the convenience and cost of manufacturing, in some embodiments, the arc-shaped opening 3 is configured as a quarter of a circular arc.

Further, in order to improve the comfort of the patient, smooth arc structures 4 are provided at two ends of the arc-shaped opening 3 of the annular component 2, and preferably, wear-proof devices are provided at the smooth arc structures 4 or directly at two ends of the opening, so as to avoid discomfort such as injury or pain caused by the arc-shaped opening when the stent is in contact with the body of the patient.

In practical operation, the wear-proof device may be a soft sleeve (such as a rubber sleeve) sleeved on the end heads at the two ends of the arc-shaped opening 3; or the pad can be arranged on the inner side surfaces of two ends of the arc-shaped opening 3, and on the basis, the pad can be made of sponge or gel materials.

To sum up, on current external fixation support structure basis, reform transform the closed ring part of top and bottom, according to knee joint and ankle joint's position and home range, set up the arc opening with the ring at this both ends to wearing to take off, wear the in-process, showing the convenience of use that has promoted the patient, especially can make patient's knee joint and ankle joint carry out abundant activity, avoided current support to receive the problem that obvious influence at these two joint mobility that lead to after wearing for a long time.

In the embodiments of the present invention, "at least one" means one or more, "and" a plurality "means two or more. "and/or" describes the association relationship of the associated objects, and means that there may be three relationships, for example, a and/or B, and may mean that a exists alone, a and B exist simultaneously, and B exists alone. Wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" and similar expressions refer to any combination of these items, including any combination of singular or plural items. For example, at least one of a, b, and c may represent: a, b, c, a and b, a and c, b and c or a and b and c, wherein a, b and c can be single or multiple.

The structure, features and effects of the present invention have been described in detail in the above embodiments shown in the drawings, but the above embodiments are only preferred embodiments of the present invention, and it should be noted that, the technical features related to the above embodiments and their preferred modes can be reasonably combined and assembled into various equivalent schemes by those skilled in the art without departing from or changing the design idea and technical effects of the present invention; therefore, the present invention is not limited to the embodiments shown in the drawings, and all changes made according to the idea of the present invention or equivalent embodiments modified to equivalent changes are within the scope of the present invention without departing from the spirit of the present invention.
