Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1-5, a universal postoperative external hand support comprises a keel and a strap 200,

the keel is composed of a plurality of keel unit pieces 100, the structure of the keel unit piece 100 is similar to that of a human spine, the keel unit piece 100 comprises a main body part 110, a connecting part 120 and a wing plate part 130, the connecting part 120 is integrally formed at the front end and the rear end of the main body part 110, the connecting part 120 at the front end and the rear end of the main body part 110 is arranged in a central symmetry manner, the connecting part 120 comprises a fixed plate 121 and a movable plate 122, the fixed plate 121 and the main body part 110 are integrally formed, the movable plate 122 is arranged opposite to the fixed plate 121 in a sliding manner, specifically, a T-shaped sliding block 1221 is arranged at the end part of the movable plate 122, a T-shaped sliding groove 1222 is arranged at the end part of the main body part 110, and the sliding groove 1222 is matched with the sliding block 1221, so that the sliding block 1221 can slide linearly along the sliding groove 1222;

a plurality of ring-shaped array of latches 1211 are disposed on the inner side of the fixed plate 121, the width and the interval of the latches 1211 are the same, the array of the latches has a structure similar to that of the face gear, wherein a first threaded hole 1212 is formed at the center of each of the ring-shaped array of latches 1211 of the fixed plate 121, and a second threaded hole 1223 corresponding to the first threaded hole 1212 is also formed at the corresponding position of the movable plate 122; a fixing bolt 140 is threadedly coupled to the first and second threaded holes 1212 and 1223,

the adjacent keel unit pieces 100 are fixedly connected through the corresponding connecting parts 120, namely, the latch 1211 of the fixing plate 121 of the connecting part 120 of the first keel unit piece 100 is butted with the latch 1211 of the fixing plate 121 of the connecting part 120 of the second keel unit piece 100, the two latches 1211 are mutually engaged, then the fixing bolt 140 passes through the two first screw holes 1212 and the two second screw holes 1223 of the two connecting parts 120, the latch 1211 of the two fixing plates 121 is locked and can not rotate by screwing the fixing bolt 140, then the included angle between the adjacent keel unit pieces 100 is fixed, the rest keel 100 is similar, the shape of the whole keel can be adjusted to be attached to the arm of the patient by adjusting the included angle between the adjacent keel unit pieces 100,

meanwhile, the fixing bolt 140 can adopt a plastic screw, and after the angle between the adjacent keel unit pieces 100 is fixed after the fixing is determined, two ends of the plastic screw are directly heated to be clamped, so that the arrangement can ensure that the fixing bolt 140 cannot slip, the keel unit pieces 100 are fixed stably, as the stress between the keel unit pieces 100 is mainly born by the clamping teeth 1211, even the plastic screw with the strength lower than that of a metal material can also sufficiently play a role in fixing, and meanwhile, the arrangement can also play a role in preventing a patient from unscrewing the bolt to adjust the angle between the keel unit pieces 100 through a wrench and a screwdriver to the extent, when the doctor needs to dismantle, the plastic screw is damaged through heating or shearing and other means, and the rest keel unit pieces 100 can be continuously used;

the left side and the right side of the main body part 110 extend upwards in an inclined manner to form the wing plate parts 130, the two wing plate parts 130 are enclosed together in an arc shape, the two wing plate parts 130 are both in an arc shape, the tail ends of the two wing plate parts 130 are fixedly connected with a binding belt 200, the tail end of one binding belt 200 is fixedly connected with a woven belt buckle 201, and the binding belt 200 can be fixed through the woven belt buckle 201.

In the second embodiment, as shown in fig. 6, the difference between the first embodiment and the second embodiment is that the connecting portion 120 may only include the fixing plate 121, but not the movable plate 122, in this arrangement, the thickness of the fixing plate 121 should be the sum of the thicknesses of the fixing plate 121 and the movable plate 122 in the first embodiment, and in this arrangement, the fixing bolt 140 should be a bolt made of metal and provided with a spring washer, and in this arrangement, there is no need to additionally provide a sliding slot in the main body part 110, so that the processing procedure is reduced, and the structural strength of the main body part can be increased.

The utility model has the advantages of simple structure, the shape of the arm of the different condition of laminating patient that can be convenient uses most structure still can continue to use through the disinfection after the while, and of course this practical support only is applicable to slight fracture, joint dislocation, if take place serious fracture condition, for example the fracture of completeness, should implant the steel nail still will implant the steel nail, and this device just is not suitable for.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
