Description

Orthopedic splint fastener

Technical Field

The invention relates to the field of medical instruments related to orthopedics, in particular to an orthopedic splint fastening device.

Background

The splint fixing technology is an external fixation type bone-knitting mode originally created by Chinese medicine orthopedics, has the advantages of easily obtained materials, convenient use, simplicity and easy learning, and less pain for patients without open surgery, but in recent years, the splint is not fixed in advance in the development of China, the main reason is that the splint fixing mode is simpler and is only fixed through a bandage, as is known, the fracture and the adjacent parts can generate serious swelling within 1 to 4 days of the fracture, and the fracture is fixed in a hospital within 1 to 5 days, even if the splint is tightly bound, the swelling begins to subside after 4 to 15 days, the swelling is a sequential process, at the moment, the binding part gradually loosens, and once the binding part loosens, the certain fixing function can be lost, thereby causing the fracture surface healing difficulty and even the condition of staggered healing, therefore, the patients need to go to the hospital to fasten again every 3 to 10 days, in order to solve the problem, some orthopedic doctors propose to fix the bone through a rubber belt with better elasticity, and the method can effectively overcome the problem of looseness caused by later-stage detumescence, but the rubber belt always keeps stronger binding and fastening force and is not beneficial to the combination of the sections, and the first overtightening can directly cause local blood circulation obstacle and aggravate the pain and swelling degree of a patient; the second splint can press the muscle tissue longitudinally too much, so that part of the muscle tissue can be extruded to the edge of the fracture surface, and the formation of external callus is not facilitated; the third excessive radial pressurization can cause the gap between the two sections to be larger, thus being not beneficial to the whole healing, and the callus can be directly generated on the end face seriously to influence the whole healing effect;

therefore, the optimal fixing mode is that the longitudinal position of the fracture of the patient can be always kept with uniform pressurizing degree by means of the splint, meanwhile, the fracture can be axially pressurized, the distance between two end faces is shortened as much as possible, the gap between the end faces can be conveniently absorbed and healed as soon as possible, the longitudinal pressurizing degree can be adjusted in tightness, the muscle of the patient can move conveniently, the limbs of the patient can be exercised, and the condition of joint stiffness or muscle atrophy is prevented.

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a top view of a positioning strip of the present invention.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the technical scheme in the embodiment of the invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the invention.

Referring to fig. 1-2, the present embodiment is realized by the following technical scheme, which comprises two positioning strips 1 made of metal material, wherein a first positioning seat 2 and a second positioning seat 3 which can be sleeved with the positioning strips 1 and are in clearance sliding fit are respectively fixed at two ends of each positioning strip 1, and the positioning strips 1 are bent into an arc-shaped structure which can be sleeved at two ends of a fracture part of a patient under the combined action of the first positioning seat 2 and the second positioning seat 3;

The following will further explain the application method and the principle of the technical solution part in this embodiment with reference to the drawings.

Firstly, placing 4 small splints around a fractured bone, primarily fixing the splints by using gauze, then sleeving two positioning strips 1 which are bent into a ring shape at two ends of each small splint, ensuring that a rubber 11 is in direct contact with the small splints, and a positioning boss 12 is in direct contact with the skin of a patient, then axially pushing the fractured bone near the two ends of the fractured bone and keeping the fractured bone still, then radially pressurizing the small splints by rotating an adjusting nut 8 through a spring 7, completely fixing the distance between the two positioning strips 1 by adjusting a locking nut 14, and axially pushing muscle tissues related to the two fractured bones all the time by the positioning boss 12, so that gaps between the fractured bones are reduced, and the gaps are favorable for later-stage rapid absorption and formation of calluses;

because the swelling of the fractured bone is temporary, the swelling starts from the first day until the swelling reaches the highest peak after 3-4 days, and the swelling slowly decreases within the next 4-20 days (the swelling starts after 15 days, which are extremely individual), the spring 7 can drive the positioning strip 1 to always maintain the optimal radial clamping force on the small splint in the process, so that the radial pressurizing force on the fractured bone is further converted through the small splint, and the radial pressurizing force and the axial pressurizing force are also adjustable and can be correspondingly adjusted according to the actual condition of a patient;

it should be noted that: the axial pressurization in the specific implementation is only suitable for the more common section symptoms that two sections are planar, for example, the X-ray film shows that the inclined section and even the bony spur have punctured the section symptom of the skin, only the radial pressurization needs to be considered at the moment, the fixation in the axial direction is kept, and once the axial pressurization is adopted, the condition of staggered healing is easily caused;

the adjusting nut 8 needs to be loosened as little as possible in the cartilage callus period, so that the young callus newly formed at the broken bone can be prevented from being broken again due to the loss of the axial pressure.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
