The utility model discloses an go up spacing handle and do: the outer surface of the circumference of the shaft of the limiting shaft is provided with a spring, one end of the limiting shaft is provided with a nut, the other end of the limiting shaft is respectively lapped with the upper limiting hole of the forearm rib, and the middle limiting handle, the lower limiting handle and the upper limiting handle have the same structure.

The utility model discloses an installation can remove forearm support piece on the forearm rib, the big arm support piece that the installation can remove on the big arm rib can adjust forearm support piece and big arm support piece's position according to patient actual conditions, the utility model is suitable for a most of patients. One end of the forearm rib is connected with the hand rib, the other end of the forearm rib is movably connected with the upper end of the rotary table through the dividing block, the elbow bending angle in a large range can be fixed, the arc-shaped gripper of the hand rib can reduce fatigue feeling of a wrist, so that the forearm can be subjected to isometric contraction training while being fixed, forearm muscle atrophy can be prevented, fracture healing can be accelerated, and scales are marked on the surface of the rotary table and can conveniently indicate the elbow bending angle. The utility model discloses portable elbow joint orthopedic ware's material is the carbon fiber, and the carbon fiber has nontoxic tasteless, and X ray transmissivity is high, uses light advantage, and whole device need not to demolish, and the observation coaptation that can be clear and the healing condition provide the assurance for the accuracy and the perfection of operation, help the doctor to go deep into and know patient's health, burden when can furthest alleviateing patient's activity.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-3, the portable elbow joint orthosis of the embodiment is formed by connecting a hand tendon 1, a forearm tendon 2, a forearm support member 3, an upper limit handle 4, a middle limit handle 5, an indexing block 6, a turntable 7, a scale 8, a large arm tendon 9, a lower limit handle 10 and a large arm support member 11.

Install forearm support piece 3 on forearm rib 2, install on forearm support piece 3 spacing handle 4, go up spacing handle piece 4 and be: the peripheral surface mounting spring 403 of spacing axle 401, nut 402 is installed to the one end of spacing axle 401, the other end and the last spacing hole b overlap joint on the forearm rib 2, draw upper limit handle 4 through external force, under the effect of spring 403, can adjust the position of forearm support piece 3 on forearm rib 2 according to patient's actual conditions, be applicable to most patients. One end of the forearm rib 2 is connected with the hand rib 1, the other end of the forearm rib is movably connected with the upper end of the rotary table 7 through the dividing block 6, and the arc-shaped gripper of the hand rib 1 can reduce fatigue feeling of the wrist, so that the forearm can be fixed and can be subjected to isometric contraction training, thereby being beneficial to preventing forearm muscle atrophy and accelerating fracture healing. The side surface of the rotary table 7 is provided with a positioning hole a, the indexing block 6 is provided with a middle limiting handle 5, the structure of the middle limiting handle 5 is the same as that of the upper limiting handle 4, the middle limiting handle 5 is lapped with the positioning hole a on the rotary table 7, when the middle limiting handle 5 is pulled, the front arm rib 2 can be positioned in the positioning hole a on the side surface of the rotary table 7 under the action of the spring, and the fixed elbow bending angle is 4-180 degrees. The dial 7 is marked with a scale 8 on the surface, and the scale 8 can conveniently indicate the elbow bending angle. Big arm rib 9 is installed to carousel 7 lower extreme, install big arm support 11 on the big arm rib 9, forearm support 3, big arm support 11 are elastic material, have the advantage of gas permeability, good elasticity and intensity, can bring the comfort for the patient, reduce the extrusion of fixed brace to patient's skin, local skin damage phenomenon appears after effectively preventing patient's arm is fixed, install lower spacing handle 10 on big arm support 11, lower spacing handle 10 is the same with the structure of last spacing handle 4, lower spacing handle 10 is lapped with lower spacing hole c on big arm rib 9, through spacing handle 10 under external force drawing, under the effect of spring, can adjust the position of big arm support 11 on big arm rib 9 according to patient's actual conditions. The material of portable elbow joint orthopedic ware is the carbon fiber, and the carbon fiber has nontoxic tasteless, and X ray transmissivity is high, uses light advantage, the utility model discloses need not to demolish, can be clear observe coaptation and the healing condition, for the accuracy and the perfection of operation provide the assurance, help the doctor to go deep into understanding patient's health, burden when furthest alleviates patient's activity.
