Detailed ways

As an important external fixation tool for fractures, the small splint has a history of thousands of years. In the process of treating fractures, it not only perfectly achieves "dynamic and static integration" and "equal emphasis on muscles and bones", but also with its technical principle of "elastic fixation". The reduction, fixation and functional exercise of fractures are skillfully combined to effectively promote the healing of fractures and the recovery of body functions.

The principle of small splint in the treatment of fractures is based on the physiological requirements of the limbs, through the binding force of the tie, the elastic fixation force of the splint, the pressure pad to prevent or correct the angular deformity of the fracture end and the effect of lateral displacement, and the effect of the limb muscle contraction activity. The internal power generated will form a physiological stimulus at the fractured end, so as to achieve the purpose of fixing the fracture and restoring the internal dynamic balance of the limb.

(1) Combination of static and dynamic

"Station" means standing still. When treating fractures with small splints, special emphasis is placed on firm fixation to ensure that the fracture site does not shift, and to create powerful conditions for correct fracture reduction and early healing. The splint fixation technique secures the affected part against angular and lateral displacement of the fracture through the external force of ties, splints, and pressure pads. "Movement" means movement, which refers to all the macroscopic and microscopic movements of the patient in the process of fracture treatment and recovery. Macroscopic movement refers to the active and passive movements performed by the patient on the affected part, including moderate functional exercise and manual therapy by doctors; microscopic movement refers to the changes in blood circulation of the affected part and the voluntary muscle contraction activities. "Combination of dynamic and static" is an important principle in the treatment of fractures. Studies have shown that appropriate activities within the physiological range are conducive to the recovery of fractures, and good fixation is the basis for appropriate activities. What the small splint fixation technology has is a kind of elastic fixation based on the principle of dynamic and static combination.

(2) Elastic fixation

The so-called "elastic fixation" refers to the phenomenon of "micro-movement" between the fracture ends during the fracture healing process. The core of small splint fixation in the treatment of fractures is "elastic fixation" under the guidance of the principle of "dynamic and static integration". There is no stress shielding of the affected limb fixed by the small splint, which can allow the patient to perform functional exercise as soon as possible. The interaction between the external power generated by the external fixation system of the small splint and the internal power generated by the muscle contraction activity during the early functional exercise can increase the stress at both ends of the fracture and produce a kind of similar muscle contraction activity between the fracture ends. Longitudinal extrusion effect, thus forming active fretting stimulation, can promote the growth of blood vessels at the fracture end, increase the activity of osteoblasts at the fracture end, accelerate the formation of periosteal callus, and promote fracture healing.

Hereinafter, the present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, on the premise of no conflict, the embodiments or technical features described below can be combined arbitrarily to form new implementations. example.

There are 3 through holes in each of the 4 plywoods. With one of the plywood as the center, the cable tie 51 passes through the center plywood. After connecting the other plywood in series, it passes through the through hole inside the center plywood again. The cable tie fixing device 15 is used for fixing. Each splint comes with a sticky tissue and a pressure pad. One side of the sticky tissue paper is sticky, and it is covered with a paper film when not in use, which can be adhered to the inner side of the splint by tearing off the paper film; the other side is designed as a Velcro surface, which can be attached to the pressure pad. One side of the pressure pad can be attached to the Velcro surface of the adhesive tissue paper and can be easily removed to change the position, and the other side is soft and smooth to be placed on the fractured end. Each patient's follow-up visit only needs to replace the clean pressure pad, wipe the splint with alcohol, and finally readjust the splint.

As a preferred embodiment, the use steps of the present utility model are: 1. Rehabilitate by manipulation; 2. Paste the pressure pad on the appropriate position on the splint; 3. Thread the cable ties 51 into the four splints; 4. Under the maintenance of traction, two main plastic splints are placed on the volar and dorsal sides, and then the ulnar plate 21 and the radial plate 41 are placed, and the distal end of the plastic splint reaches the middle of the metacarpal; It is advisable that the strap 51 can move up and down in the through hole, and press the strap fixing device 15 on the center splint to fix it; 6. According to the previous clinical research, when the tensile force of the strap 51 is 0.75kg, it can not only maintain the fracture position, but also prevent the fracture. Tension blisters appear. After the plastic splint was fixed for half a month, the normal splint was replaced with a neutral position fixation, and the distal end of the splint was 1.5 cm beyond the wrist joint. Within 1 week after immobilization, the tie 51 is prone to loosening due to the absorption of the hematoma, and it is reviewed every two days to adjust the tightness of the splint. The splint is so tight that the tie 51 can maintain the up and down movement of 1 cm. Immediate, 1 week, half a month, 1 month, and 3 months after the fixation, the radiographs were reviewed.

The meshing of the upper and lower tooth columns is incomplete, only the tooth tips are partially engaged, and the guide rail 153 behind the two engaged teeth is designed to slide in the same guide groove, and the lower tooth column is pushed down by the upper tooth column. After the groove, under the elastic force of the spring 154, the teeth of the lower teeth will slide along the inclined surface of the teeth of the meshed upper teeth. On one side, the lower tooth column is pressed down so that the tie 51 is fixed firmly.

The cable tie 51 passes through the metal frame 52 and the through hole of the center splint in turn after a circle. After adjusting the tightness, it is appropriate that the cable tie 51 can move up and down in the through hole. The tie fixing device 15 above the central splint through hole is used for fixing, so that the splint can fix the affected limb without stress shielding, and can give a certain physiological stimulation to the fractured end to promote the healing of the fracture. Compared with the traditional small splint or most of the improved new splints, the bandage is tied and knotted from the outside of the splint, the fixation is more reliable and the adjustment is more convenient, which effectively avoids the problem of the splint being loosened or fixed too tightly, thereby preventing fractures.
